DETAILED DESCRIPTION OF EMBODIMENTS

Embodiments of the present disclosure will be described below with reference to the accompanying drawings. It should be understood, however, that these descriptions are merely exemplary and are not intended to limit the scope of the present disclosure. In the following detailed description, for ease of interpretation, many specific details are set forth to provide a comprehensive understanding of embodiments of the present disclosure. However, it is clear that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concepts of the present disclosure.

Terms used herein are for the purpose of describing specific embodiments only and are not intended to limit the present disclosure. The terms “including”, “containing”, etc. used herein indicate the presence of the feature, step, operation and/or component, but do not exclude the presence or addition of one or more other features, steps, operations or components.

All terms (including technical and scientific terms) used herein have the meanings generally understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein shall be interpreted to have meanings consistent with the context of this specification, and shall not be interpreted in an idealized or overly rigid manner.

In a case of using the expression similar to “at least one of A, B and C”, it should be explained according to the meaning of the expression generally understood by those skilled in the art (for example, “a system including at least one of A, B and C” should include but not be limited to a system including A alone, a system including B alone, a system including C alone, a system including A and B, a system including A and C, a system including B and C, and/or a system including A, B and C). In a case of using the expression similar to “at least one of A, B or C”, it should be explained according to the meaning of the expression generally understood by those skilled in the art (for example, “a system including at least one of A, B or C” should include but not be limited to a system including A alone, a system including B alone, a system including C alone, a system including A and B, a system including A and C, a system including B and C, and/or a system including A, B and C).

A controller in a display device may be used to control a display module to display at least one image. In a process of switching between two adjacent images, it is needed to firstly eliminate a display of a previous image and then display a current image, and then an evolution process including image clipping, background repainting, and image clipping may occur in an overlapping region of the two adjacent images. Accordingly, a pixel value in the overlapping region may change, resulting in a flickering process from bright to dark and then to bright. The flickering process may be recognized by a user, which affects a user experience.

FIG. 1 schematically shows an example schematic diagram of switching between two adjacent images.

As shown in FIG. 1, in 100, an image 101 and an image 102 are two adjacent images. There is an overlapping region between the image 101 and the image 102. During a process of switching from displaying the image 101 to displaying the image 102, the overlapping region between the image 101 and the image 102 may exhibit a change from bright to dark and then to bright.

Therefore, the embodiments of the present disclosure propose a display device. For example, the display device may include a memory, a controller, and a display module. The memory is used to store at least one pre-stored image. The controller is used to: obtain a first target image and a second target image according to the at least one pre-stored image; control the display module, according to the first control instruction, to display the second target image and hide a display of at least one first sub-region in a first region in a frame displayed after switching from the first target image to the second target image. A size of the first target image is different from a size of the second target image, and/or a position of the first target image in a display picture is different from a position of the second target image in the display picture. The first region represents a region located within an outer contour of the first target image and not overlapping with the second target image.

According to the embodiments of the present disclosure, since the controller controls the display module, according to the first control instruction, to display the second target image in the frame displayed after switching from the first target image to the second target image, the second target image may directly cover the overlapping region between the first target image and the second target image in the frame displayed after switching from the first target image to the second target image, so that the flickering process from bright to dark and then to bright during the switching from the first target image to the second target image may be effectively avoided, thereby improving a display effect and a user viewing experience.

Alternatively, the second parameter information may include an eighteenth position information and a second angle information. In addition, the first parameter information may further include the head address of the first target image, and the second parameter information may further include the head address of the second target image. When it is determined that the first target image is stored in the memory 201, the first target image may be acquired from the memory 201 according to the head address of the first target image. When it is determined that the second target image is stored in the memory 201, the second target image may be acquired from the memory 201 according to the head address of the second target image.

According to the embodiments of the present disclosure, the first region may include at least one first sub-region. The first sub-region may be obtained by dividing the first region according to a positional relationship between the first region and the second target image.

According to the embodiments of the present disclosure, the first control instruction may refer to a control instruction for a complete process of the controller 202 controlling the display module 203 to switch from the first target image to the second target image and completely hide all parts of the first target image. The frame displayed after switching from the first target image to the second target image may refer to a frame in which the second target image is first displayed during the process of switching from the first target image to the second target image.

For example, the first region may include at least one of a first sub-region A1, a first sub-region A2, a first sub-region A3, and a first sub-region A4. In the frame displayed after switching from the first target image to the second target image, the second target image may be displayed, and a display of the first sub-region A1 may be hidden. Alternatively, in the frame displayed after switching from the first target image to the second target image, the second target image may be displayed, and a display of the first sub-region A1 and the first sub-region A2 may be hidden. Alternatively, in the frame displayed after switching from the first target image to the second target image, the second target image may be displayed, and a display of the first sub-region A1, the first sub-region A2 and the first sub-region A3 may be hidden. Alternatively, in the frame displayed after switching from the first target image to the second target image, the second target image may be displayed, and a display of the first region may be hidden.

According to the embodiments of the present disclosure, a display content of the display picture of the display module 203 in the frame displayed after switching from the first target image to the second target image may be determined according to a processing speed of the controller 202. For example, the operations of hiding the display of each first sub-region in the first region are sequentially performed step by step. For example, the first region may include the first sub-region A1, the first sub-region A2, the first sub-region A3, and the first sub-region A4. The controller 202 may eliminate the first sub-region A1, the first sub-region A2, the first sub-region A3 and the first sub-region A4 in a predetermined order. For example, the first sub-region may be set to be consistent with a bottom color of the second target image or a predetermined background color. In a case of a high processing speed of the controller 202, the controller 202 may control the display module 203, according to the first control instruction, to display the second target image and hide the display of the first sub-region A1, the first sub-region A2, the first sub-region A3 and the first sub-region A4. Accordingly, in the frame displayed after switching from the first target image to the second target image, the first target image is completely hidden on the display module 203. For example, in a case of a low processing speed of the controller 202, the controller 202 may control the display module 203, according to the first control instruction, to only hide the display of at least one of the first sub-region A1, the first sub-region A2, the first sub-region A3 and the first sub-region A4. Accordingly, in the frame displayed after switching from the first target image to the second target image, the second target image and the other first sub-regions in the first target image that are not hidden are presented on the display module 203.

It may be understood that the processing speed of the controller 202 may also determine that in the frame displayed after switching from the first target image to the second target image, the second target image and the other two or three first sub-regions in the first target image that are not hidden are presented on the display module 203.

It may be understood that the first region may only include at least one of the first sub-region A1, the first sub-region A2, the first sub-region A3, or the first sub-region A4. In this case, the controller 202 may perform a determination operation of determining the number of first sub-regions in the first region, and only process an existing first sub-region, so as to improve a processing efficiency.

It may be understood that an order in which the controller 202 processes the first sub-regions in the first region may be determined according to actual service needs and is not limited here.

According to the embodiments of the present disclosure, the controller 202 may generate the first control instruction upon a detection of switching from the first target image to the display of the second target image. The controller 202 may control the display module 203, according to the first control instruction, to display the second target image and hide the display of at least one first sub-region in the first region in the frame displayed after switching from the first target image to the second target image, so that the second target image may cover the overlapping region between the first target image and the second target image, and that the at least one first sub-region in the first region is not displayed on the display module 203 when the second target image is displayed on the display module 203. It should be noted that hiding the display of the first sub-region may mean that a color of the first sub-region is consistent with a bottom color of the second target image or a predetermined background color. The bottom color of the second target image may be the predetermined background color.

For example, the controller 202 may control the display module 203, according to the first control instruction, to display the second target image in the frame displayed after switching from the first target image to the second target image, and call a background painting routine to set a pixel value of the at least one first sub-region to be consistent with a pixel value of the bottom color of the second target image or a pixel value of the predetermined background.

The controller controlling the display module, according to the first control instruction, to display the second target image and hide the display of at least one first sub-region in the first region according to the embodiments of the present disclosure will be further described below with reference to FIG. 2B in combination with specific embodiments.

FIG. 2B schematically shows an example schematic diagram of the controller controlling the display module, according to the first control instruction, to display the second target image and hide the display of at least one first sub-region in the first region according to the embodiments of the present disclosure.

As shown in FIG. 2B, in 200B, a region located within the outer contour of the first target image 204 and not overlapping with the second target image 205 is a first region 204_1. The first region 204_1 may include a first sub-region 204_1_1 and a first sub-region 204_1_2. As shown in FIG. 2B, the first sub-region 204_1_1 is located on a right side of the second target image 205, and the first sub-region 204_1_2 is located on a lower side of the second target image 205.

The controller may control the display module to display in the following order according to the first control instruction: displaying the second target image 205 and maintaining the display of the first region 204_1; hiding the display of the first sub-region 204_1_1; hiding the display of the first sub-region 204_1_2. In the frame displayed after switching from the first target image to the second target image, the display module 203 displays the second target image and hides the display of the first sub-region 204_1_1. Alternatively, in the frame displayed after switching from the first target image to the second target image, the display module 203 displays the second target image and hides the display of the first region 204_1.

According to the embodiments of the present disclosure, since the controller controls the display module to display the second target image according to the first control instruction, the second target image may directly cover the overlapping region between the first target image and the second target image in the frame displayed after switching from the first target image to the second target image, so that the flickering process from bright to dark and then to bright during the switching from the first target image to the second target image may be effectively avoided, thereby improving a display effect and a user viewing experience.

According to the embodiments of the present disclosure, the contour shape of the pre-stored image may be a rectangle.

According to the embodiments of the present disclosure, a size of the pre-stored image is less than a size of the display picture of the display module.

According to the embodiments of the present disclosure, the pre-stored image may be obtained by performing an image compression on the original image. For example, the image compression may include at least one of clipping or capturing. The size of the pre-stored image is less than the size of the original image. The size of the original image may be less than or equal to the size of the display picture of the display module. The pre-stored image may include a valid information of the original image.

According to the embodiments of the present disclosure, the pre-stored image may be obtained by clipping the original image based on an edge contour of the valid information of the original image. Alternatively, the controller 202 may clip the original image based on a predetermined clipping box to obtain the pre-stored image. The valid information of the original image may be determined according to a pixel value of a pixel in the original image. A shape of the predetermined clipping box may be determined according to actual service needs and is not limited here. For example, the shape of the predetermined clipping box may include a rectangle.

The parameter information of a pre-stored image 304 may include a component position information and a size information of the pre-stored image 304. The pre-stored image 304 may be obtained by performing an image clipping on the original image 304. The pre-stored image 304 may include a pre-stored sub-image 304_1 and a pre-stored sub-image 304_2.

According to the storage space “1.152 MB” occupied by the original image 303 and the storage space “51 KB=(18+33) KB” occupied by the pre-stored image 304, it may be concluded that the storage space occupied by the pre-stored image 304 is reduced by performing an image clipping on the original image 303.

According to the embodiments of the present disclosure, an expected storage space occupied by the original image may be determined according to a resolution information (i.e., size information) of the display screen of the display module and an interface complexity of UI (User Interface). When it is determined that an actual storage space of the memory 201 is less than the expected storage space, it may be determined that the storage space of the original image is reduced by using a compression algorithm. For example, the storage space occupied by the original image is 1.152 MB, and the storage space occupied by the pre-stored image obtained by clipping the original image is 84.672 KB. The storage space occupied by the original image is 1.152 MB, and the storage space occupied by the pre-stored image obtained by clipping the original image is 33 KB.

According to the embodiments of the present disclosure, by clipping the original image to obtain the pre-stored image stored in the memory, the storage space for the pre-stored image is reduced, thereby maximizing a utilization of the storage space of the memory and reducing a storage cost.

When it is determined that the first region includes a first target sub-region according to the positional relationship, the controller 202 controls the display module 203, according to the first control instruction, to display the second target image and hide the display of the first target sub-region. Alternatively, when it is determined that the first region includes the first target sub-region and a second target sub-region according to the positional relationship, the controller 202 controls the display module 203, according to the first control instruction, to display the second target image and hide the display of the first target sub-region and the second target sub-region. Alternatively, when it is determined that the first region includes the first target sub-region, the second target sub-region and a third target sub-region according to the positional relationship, the controller 202 controls the display module 203, according to the first control instruction, to display the second target image and hide the display of the first target sub-region, the second target sub-region and the third target sub-region. Alternatively, when it is determined that the first region includes the first target sub-region, the second target sub-region, the third target sub-region and a fourth target sub-region according to the positional relationship, the controller 202 controls the display module 203, according to the first control instruction, to display the second target image and hide the display of the first target sub-region, the second target sub-region, the third target sub-region and the fourth target sub-region.

According to the embodiments of the present disclosure, the first target sub-region may be a first sub-region located on a side of the second target image in a first direction, the second target sub-region may be a first sub-region located on a side of the second target image in a second direction, the third target sub-region may be a first sub-region located on a side of the second target image in a third direction, and the fourth target sub-region may be a first sub-region located on a side of the second target image in a fourth direction.

According to the embodiments of the present disclosure, the first direction and the third direction may be perpendicular to each other, and the second direction and the fourth direction may be perpendicular to each other. Alternatively, the first direction and the second direction may be perpendicular to each other, and the third direction and the fourth direction may be perpendicular to each other. Alternatively, the first direction and the fourth direction may be perpendicular to each other, and the second direction and the third direction may be perpendicular to each other.

According to the embodiments of the present disclosure, the first target sub-region may be a first sub-region located on a side of the second target image in the first direction, and the second target sub-region may be a first sub-region located on a side of the second target image in the second direction. When the controller 202 performs the operations of hiding the display of the first sub-region in the order from the first target sub-region to the second target sub-region, if there is an overlapping region between the first target sub-region and the second target sub-region, the operations may be performed by at least four processing methods as follows.

Method 1: The overlapping region is hidden during the process of hiding the display of the first target sub-region, and in a case of performing the operation of hiding the display of the second target sub-region, the display of the second target sub-region is hidden. That is, the operation of hiding the display of the overlapping region is repeatedly performed.

Method 2: The controller 202 may determine a region in the second target sub-region not overlapping with the first target sub-region according to the first parameter information of the first target sub-region and the first parameter information of the second target sub-region. The controller 202 may control the display module 203 to hide the display of the first target sub-region and hide the display of the region in the second target sub-region not overlapping with the first target sub-region. That is, when performing the operation of hiding the display of the second target sub-region, the controller 202 hides the display of the region in the second target sub-region not overlapping with the first target sub-region, and the operation of hiding the display of the overlapping region between the second target image and the first target image is not repeatedly performed.

Method 3: The controller 202 may determine a region in the first target sub-region not overlapping with the second target sub-region according to the first parameter information of the first target sub-region and the first parameter information of the second target sub-region. The controller 202 may control the display module 203 to hide the display of the region in the first target sub-region not overlapping with the second target sub-region and hide the display of the second target sub-region.

Method 4: It is possible to predetermine which first sub-region the overlapping region between the two first sub-regions belongs to. For the overlapping region between the first target sub-region and the second target sub-region, it may be predetermined whether the overlapping region belongs to the first target sub-region or the second target sub-region. If the overlapping region belongs to the first target sub-region, the controller 202 may control the display module 203 to hide the display of the first target sub-region and hide the display of a sub-region other than the overlapping region in the second target sub-region. If the overlapping region belongs to the second target sub-region, the controller 202 may control the display module 203 to hide the display of a sub-region other than the overlapping region in the first target sub-region and hide the display of the second target sub-region. In this way, the operation of hiding the display of the overlapping region may be performed once only.

According to the embodiments of the present disclosure, the first direction and the second direction are perpendicular to each other. For example, the first direction of the second target image is a direction toward a right side of the second target image, and the second direction of the second target image is a direction toward a lower side of the second target image.

For example, the first direction of the second target image is the direction toward the right side of the second target image, and the second direction of the second target image is the direction toward the lower side of the second target image. One or more first sub-regions are respectively located on the sides of the second target image in the first target direction, the second target direction, the third target direction, and the fourth target direction.

For example, the first direction and the third direction may be parallel to the row extension direction of the pixel arrangement of the second target image. The second direction and the fourth direction may be parallel to the column extension direction of the pixel arrangement of the second target image.

For example, the first direction for the second target image may be the direction toward the right side of the second target image, the second direction for the second target image may be the direction toward the lower side of the second target image, the third direction for the second target image may be the direction toward the left side of the second target image, and the fourth direction for the second target image may be the direction toward the upper side of the second target image. According to the embodiments of the present disclosure, two of the first direction, the second direction, the third direction and the fourth direction are parallel to each other, and the other two are parallel to each other.

As shown in FIG. 4B, on the basis of FIG. 4A, in 400B, a first target sub-region 402_1 is the first sub-region located on the side of the second target image 401 in the first direction, and a second target sub-region 402_2 is the first sub-region located on the side of the second target image 401 in the second direction. A first direction 403 and a second direction 404 are perpendicular to each other. The first direction 403 may be parallel to the row extending direction of the pixel arrangement of the second target image 401, and the second direction 404 may be parallel to the column extending direction of the pixel arrangement of the second target image 402.

The first region may represent a region located within the outer contour of the first target image 402 and not overlapping with the second target image 401. The first region may include the first target sub-region 402_1 and the first target sub-region 402_2.

The first target sub-region 402_1 may include a non-overlapping region 402_10 and an overlapping region 402_20. The second target sub-region 402_2 may include a non-overlapping region 402_30 and the overlapping region 402_20. The overlapping region 402_20 may be the overlapping region between the first target sub-region 402_1 and the second target sub-region 402_2.

It may be predetermined whether the overlapping region 402_20 belongs to the first target sub-region 402_1 or the second target sub-region 402_2. When the overlapping region 402_20 belongs to the first target sub-region 402_1, the controller may control the display module to hide the display of the first target sub-region 402_1 and hide the display of the non-overlapping region 402_30. When the overlapping region 402_20 belongs to the second target sub-region 402_2, the controller may control the display module to hide the display of the non-overlapping regions 402_10 and hide the display of the second target sub-region 402_2.

In this way, the operation of hiding the display of the overlapping region 402_20 may be performed once only, so that the display efficiency may be improved.

According to the embodiments of the present disclosure, the controller 202 may control the display module 203, according to the first control instruction, to display the second target image and hide the display of at least partial region on the side of the second target image in the first direction. Alternatively, the controller 202 may control the display module 203, according to the first control instruction, to display the second target image and hide the display of at least partial regions on the sides of the second target image in the first direction and the second direction. Alternatively, the controller 202 may control the display module 203, according to the first control instruction, to display the second target image and hide the display of at least partial regions on the sides of the second target image in the first direction, the second direction and the third direction. Alternatively, the controller 202 may control the display module 203, according to the first control instruction, to display the second target image and hide the display of at least partial regions on the sides of the second target image in the first direction, the second direction, the third direction and the fourth direction. Alternatively, the controller 202 may control the display module 203, according to the first control instruction, to display the second target image and hide the display of the first region.

According to the embodiments of the present disclosure, two of the first direction, the second direction, the third direction and the fourth direction are parallel to the row extending direction of the pixel arrangement of the second target image, and the other two are parallel to the column extending direction of the pixel arrangement of the second target image.

According to the embodiments of the present disclosure, when it is determined that the first target image and the second target image have the translation relationship according to the positional relationship, the controller 202 controls the display module 203 to display the second target image and hide the display of the first sub-region in the translation direction according to the first control instruction, and does not need to perform an operation of determining a presence of the first sub-region in other directions, so that the processing efficiency of the controller 203 may be improved.

When a frame of display picture contains a plurality of target images, if the controller sequentially controls the display module to display each target image according to an execution order, a display order of each target image may be recognized by the user, resulting in a sense of image loading.

In view of this, the embodiments of the present disclosure propose an effective technical solution to avoid the sense of image loading. For example, the controller 202 may include a display buffer and a processor. The display buffer may store a plurality of target images. The processor may generate a second control instruction for the plurality of target images in response to a detection of a synchronous display instruction, and control the display module 203, according to the second control instruction, to synchronously display the plurality of target images in a same frame of display picture.

According to the embodiments of the present disclosure, the plurality of target images may be stored according to respective third parameter information of the plurality of target images. The third parameter information may include a fifth position information. Alternatively, the third parameter information may include a sixth position information and a third size information.

According to the embodiments of the present disclosure, the synchronous display instruction may refer to an instruction for switching to the plurality of target images in the same frame of display picture. A synchronous display may refer to switching to the plurality of target images in the same frame of display picture. In a frame before the same frame, none of the plurality of target images is displayed in the display picture, or in the frame before the same frame, N target images among M target images are displayed in the display picture, where M-N may be greater than or equal to 2, and M may represent a number of the plurality of target images.

According to the embodiments of the present disclosure, the processor may generate the second control instruction for the plurality of target images upon a detection of the synchronous display instruction. The processor may control the display module 203, according to the second control instruction, to synchronously display the plurality of target images stored in the display buffer in the same frame of display picture.

According to the embodiments of the present disclosure, if the sense of image loading is not obvious to the user during the process of switching to the plurality of target images in the same frame of display picture, it may be indirectly determined that the above-mentioned effective technical solution to avoid the sense of image loading has been adopted.

According to the embodiments of the present disclosure, the processor controls the display module, according to the second control instruction, to synchronously display the plurality of target images stored in the display buffer in the same frame of display picture, and the synchronous display of the plurality of target images is achieved, thereby effectively avoiding the sense of image loading caused by sequentially displaying the plurality of target images.

According to the embodiments of the present disclosure, the processor may generate a sixth control instruction according to the plurality of target images and respective third parameter information of the plurality of target images, and store, according to the sixth control instruction, the plurality of target images in the display buffer according to the respective third parameter information of the plurality of target images.

According to the embodiments of the present disclosure, the third parameter information of the plurality of target images may include a head address and a fifth position information. Alternatively, the third parameter information may include the head address, a sixth position information, and a third size information. The processor may generate the sixth control instruction according to the plurality of target images and the respective third parameter information of the plurality of target images, and store, according to the sixth control instruction, the plurality of target images in the display buffer according to the respective third parameter information of the plurality of target images.

According to the embodiments of the present disclosure, for a target image in the plurality of target images, the processor may acquire at least one pre-stored image from the memory 201 according to the head address of the target image. The plurality of target images may be obtained according to at least one pre-stored image.

According to the embodiments of the present disclosure, the processor may store the target image in the display buffer according to the fifth position information of the target image. Alternatively, the processor may store the target image in the display buffer according to the sixth position information and the third size information.

According to the embodiments of the present disclosure, the plurality of target images may include a second target image and a third target image.

According to the embodiments of the present disclosure, a size of the third target image may be different from the size of the first target image, and/or a position of the third target image in the display picture may be different from the position of the first target image in the display screen, which may include the following cases.

The size of the third target image is different from the size of the first target image, and the display position of the third target image in the display picture is different from the display position of the first target image in the display picture.

Alternatively, the size of the third target image is different from the size of the first target image, and the display position of the third target image in the display picture is the same as the display position of the first target image in the display picture. For example, the display position information of the third target image includes a same component position information as the display position information of the first target image.

Alternatively, the size of the third target image is the same as the size of the first target image, and the display position of the third target image in the display picture is different from the display position of the first target image in the display picture.

Alternatively, the size of the third target image is the same as the size of the first target image, and the display position of the third target image in the display picture is the same as the display position of the first target image in the display picture.

According to the embodiments of the present disclosure, the size of the third target image may be different from the size of the second target image, and/or the display position of the third target image in the display picture may be different from the display position of the first target image in the display picture, which may include the following cases.

The size of the third target image is different from the size of the second target image, and the display position of the third target image in the display picture is different from the display position of the second target image in the display picture.

Alternatively, the size of the third target image is different from the size of the second target image, and the display position of the third target image in the display picture is the same as the display position of the second target image in the display picture. For example, the display position information of the third target image includes a same component position information as the display position information of the second target image.

Alternatively, the size of the third target image is the same as the size of the second target image, and the display position of the third target image in the display picture is different from the display position of the second target image in the display picture.

According to the embodiments of the present disclosure, the processor may control the display module 203, according to the second control instruction, to synchronously display the second target image and the third target image in the same frame of display picture.

In order to effectively avoid picture flickering, before controlling the display module to display a fifth target image, the controller needs to determine an overlapping region between a fourth target image and the fifth target image and a region located within an outer contour of the fourth target image and not overlapping with the fifth target image. A time consumption for the above process is limited by the processing speed of the controller. Therefore, when it is needed to rapidly display the fifth target image, it is difficult to achieve a rapid display of the fifth target image due to a limitation of the processing speed of the controller.

In view of this, the embodiments of the present disclosure propose a technical solution for rapidly displaying the second target image based on caching and synchronization. For example, the controller 202 may determine a second region based on an initiation identification according to a fourth parameter information of the fourth target image and a fifth parameter information of the fifth target image.

According to the embodiments of the present disclosure, the controller 202 generates a third control instruction according to the fourth parameter information of the second region, the fourth target image, and the fifth parameter information. The controller 202 controls the display module 203, according to the third control instruction, to display the fifth target image and hide the display of at least one second sub-region in the second region in a frame displayed after switching from the fourth target image to the fifth target image.

According to the embodiments of the present disclosure, the controller 202 firstly determines the second region based on the initiation identification according to the fourth parameter information of the fourth target image and the fifth parameter information of the fifth target image, and then generates the third control instruction according to the fourth parameter information of the second region, the fourth target image, and the fifth parameter information.

According to the embodiments of the present disclosure, the initiation identification may indicate an initiation of an operation of processing the fifth target image while the fourth target image is being displayed.

According to the embodiments of the present disclosure, the second region may represent a region located within the outer contour of the fourth target image and not overlapping with the fifth target image.

According to the embodiments of the present disclosure, the fourth parameter information may include a seventh position information. Alternatively, the fourth parameter information may include an eighth position information and a fourth size information.

According to the embodiments of the present disclosure, the fifth parameter information may include a ninth position information. Alternatively, the fifth parameter information may include a tenth position information and a fifth size information.

The second region may indicate a region located within the outer contour of the fourth target image and not overlapping with the fifth target image. The initiation identification may represent an initiation of the operation of processing the fifth target image while the fourth target image is being displayed.

According to the embodiments of the present disclosure, since the controller initiates the operation of processing the fifth target image while the fourth target image is being displayed, the fifth target image may be processed while the fourth target image is being displayed, thereby improving the display smoothness.

In addition, the operation of displaying the fifth target image is initiated after the display of the fourth target image is completed, thereby further improving the display smoothness. The display of the fourth target image being completed may refer to the end of the display of the fourth target image.

According to the embodiments of the present disclosure, a driving signal and a pre-stored image signal exist simultaneously in the process of the controller 202 controlling the display module 203 to display the fourth target image.

According to the embodiments of the present disclosure, a display duration of the fourth target image may be one frame only. That is, in a first predetermined period, only one frame of the complete fourth target image is presented on the display module 203. Since the controller initiates the operation of processing the fifth target image while the fourth target image is being displayed, the fifth target image may be presented completely in a next frame to the fourth target image, thereby improving the display smoothness. The first predetermined period may be determined according to actual service needs and is not limited here. For example, the first predetermined period may be a period of three frames in length.

According to the embodiments of the present disclosure, a display duration of the fifth target image may be one frame only. That is, in a second predetermined period, only one frame of the complete fifth target image is presented on the display module 203. The second predetermined period may be determined according to actual service needs and is not limited here. For example, the second predetermined period may be a period of three frames in length. In addition, the second predetermined period may be the same as or different from the first predetermined period.

In an embodiment, the third control instruction may be the first control instruction when the fourth target image is the first target image and the fifth target image is the second target image.

According to the embodiments of the present disclosure, the driving signal and the pre-stored image signal exist simultaneously in the process of the controller 202 controlling the display module 203 to display the first target image. For example, the driving signal and the pre-stored image signal existing simultaneously may mean that the driving signal and the pre-stored signal may be detected at a same time instant.

According to the embodiments of the present disclosure, the driving signal may represent a signal allowing the controller 202 to drive the display module 203 to display. The pre-stored image signal may represent a signal allowing the memory 201 to transmit the pre-stored image to the controller 202.

According to the embodiments of the present disclosure, the driving signal may include at least one of RGB signal, LVDS (Low Voltage Differential Signaling), or MIPI (Mobile Industry Processor Interface) signal. The pre-stored image signal may include an SPI signal.

According to the embodiments of the present disclosure, the second target image may be obtained by the controller 202 by acquiring the pre-stored image from the memory, and the pre-stored image signal may be generated in an acquisition process. Therefore, in the process of the controller 202 controlling the display module 203 to display the first target image, if the driving signal and the pre-stored image signal exist simultaneously, it may mean that the second target image is processed during the process of displaying the first target image.

According to the embodiments of the present disclosure, since the driving signal and the pre-stored image signal exist simultaneously during the process of the controller controlling the display module to display the first target image, the second target image may be processed during the display of the first target image, thereby improving the display smoothness.

According to the embodiments of the present disclosure, the display duration of the first target image may be one frame only. That is, in a third predetermined period, only one frame of the complete first target image is presented on the display module 203. Since the controller 202 initiates the operation of processing the second target image during the display of the first target image, the second target image may be presented completely in a next frame to the first target image, thereby improving the display smoothness. The third predetermined period may be determined according to actual service needs and is not limited here. For example, the third predetermined period may be a period of three frames in length. In addition, the third predetermined period may be the same as or different from at least one of the first predetermined period or the second predetermined period.

According to the embodiments of the present disclosure, the display duration of the second target image may be one frame only. That is, in a fourth predetermined period, only one frame of the complete second target image is presented on the display module 203. The fourth predetermined period may be determined according to actual service needs and is not limited here. For example, the fourth predetermined period may be a period of three frames in length. In addition, the fourth predetermined period may be the same as or different from at least one of the first predetermined period, the second predetermined period or the third predetermined period.

In an embodiment, the controller 202 may control the display module 203, according to the first control instruction, to display the second target image and completely hide the display of the first region in the frame displayed after switching from the first target image to the second target image.

In an embodiment, while the second target image is being displayed, the controller 202 initiates an operation of processing the third target image, so that the third target image may be presented completely in a next frame to the second target image, thereby improving the display smoothness.

According to the embodiments of the present disclosure, since the display duration of the complete second target image may be one frame, it may maintain the same refresh rate as the display module 203, so that the display is smooth.

The rapid display of the fifth target image by the display device according to the embodiments of the present disclosure will be further described below with reference to FIG. 5 in conjunction with specific embodiments.

FIG. 5 schematically shows a schematic diagram of a display device rapidly displaying the fifth target image according to the embodiments of the present disclosure.

As shown in FIG. 5, a display device 500 may include a memory 501, a controller 502, and a display module 503.

The controller 501 may determine a second region based on an initiation identification according to the fourth parameter information of the fourth target image and the fifth parameter information of the fifth target image, generate a third control instruction according to the fourth parameter information of the second region, the fifth target image and the fifth parameter information, and control the display module 203, according to the third control instruction, to display the fifth target image and hide the display of the second region in a frame displayed after switching from the fourth target image to the fifth target image.

According to the embodiments of the present disclosure, the controller 202 may determine, in response to a detection of a switching instruction, an eighth parameter information according to a sixth parameter information of a sixth target image and a seventh parameter information of a seventh target image, obtain an eighth target image according to the eighth parameter information, the sixth target image and the seventh target image, generate a fourth control instruction according to the eighth target image and the eighth parameter information of the eighth target image, and control the display module 203 to display the eighth target image according to the fourth control instruction.

According to the embodiments of the present disclosure, the switching instruction may represent an instruction for switching from the complete display of the sixth target image to the display of the seventh target image. The sixth target image and the seventh target image may have a scaling relationship.

According to the embodiments of the present disclosure, the sixth parameter information may include an eleventh position information. Alternatively, the sixth parameter information may include a twelfth position information and a sixth size information.

According to the embodiments of the present disclosure, the seventh parameter information may include a thirteenth position information. Alternatively, the seventh parameter information may include a fourteenth position information and a seventh size information.

According to the embodiments of the present disclosure, the eighth parameter information may include a fifteenth position information. Alternatively, the eighth parameter information may include a sixteenth position information and an eighth size information.

According to the embodiments of the present disclosure, the sixth target image and the seventh target image having a scaling relationship may mean that the seventh target image is obtained by reducing or enlarging the sixth target image. Alternatively, the sixth target image may be obtained by reducing or enlarging the seventh target image.

According to the embodiments of the present disclosure, upon a detection of a switching instruction, the controller 202 may determine the eighth parameter information according to the sixth parameter information and the seventh parameter information. For example, upon a detection of a switching instruction, the controller 202 may obtain a sixteenth position information according to a first predetermined coefficient, the twelfth position information and the fourteenth position information, and obtain the eighth size information according to a second predetermined coefficient, the sixth size information and the seventh size information. The first predetermined coefficient and the second predetermined coefficient may be integers greater than 0 and less than 1. The first predetermined coefficient and the second predetermined coefficient may be determined according to actual service needs and are not limited here. For example, the first predetermined coefficient and the second predetermined coefficient may be 0.5.

For example, the twelfth position information may include the horizontal coordinate of a first lower left vertex and the vertical coordinate of the first lower left vertex of the sixth target image. The fourteenth position information may include the horizontal coordinate of a second lower left vertex and the vertical coordinate of the second upper left vertex of the seventh target image. The sixteenth position information may include the horizontal coordinate of a third lower left vertex and the vertical coordinate of the third lower left vertex. The sixth size information may include a first width information and a first height information. The seventh size information may include a second width information and a second height information. The eighth size information may include a third width information and a third height information.

The horizontal coordinate of the third lower left vertex may be determined according to the first predetermined coefficient, the horizontal coordinate of the first lower left vertex, and the horizontal coordinate of the second lower left vertex. The vertical coordinate of the third lower left vertex may be determined according to the first predetermined coefficient, the vertical coordinate of the first lower left vertex, and the vertical coordinate of the second lower left vertex.

The third width information may be determined according to the second predetermined coefficient, the first width information, and the second width information. The third height information may be determined according to the second predetermined coefficient, the first height information, and the second height information.

According to the embodiments of the present disclosure, the controller 202 may process a target image with a larger size in the sixth target image and the seventh target image according to the eighth parameter information, so as to obtain the eighth target image. For example, when it is determined that the target image with the larger size in the sixth target image and the seventh target image is the sixth target image, the controller 202 may process the sixth target image according to the eighth parameter information to obtain the eighth target image. When it is determined that the target image with the larger size in the sixth target image and the seventh target image is the seventh target image, the controller 202 may process the seventh target image according to the eighth parameter information to obtain the eighth target image.

Obtaining the eighth target image according to the eighth parameter information, the sixth target image and the seventh target image according to the embodiments of the present disclosure will be further described below with reference to FIG. 6 in conjunction with specific embodiments.

FIG. 6 schematically shows an example schematic diagram of obtaining the eighth target image according to the eighth parameter information, the sixth target image and the seventh target image according to the embodiments of the present disclosure.

As shown in FIG. 6, in 600, the sixth parameter information of the sixth target image 601 may include a twelfth position information and a sixth size information. The twelfth position information includes the horizontal coordinate and the vertical coordinate of a first lower left vertex of the sixth target image 601. The sixth size information may include a first width information and a first height information. The horizontal coordinate of the first lower left vertex is “336”. The vertical coordinate of the first lower left vertex is “176”. The first width information is “128”. The first height information is “128”.

The seventh parameter information of the seventh target image 603 may include a fourteenth position information and a seventh size information. The fourteenth position information includes the horizontal coordinate and the vertical coordinate of the second lower left vertex of the seventh target image 603.

The vertical coordinate of the second lower left vertex is “156”. The second width information is “168”. The second height information is “168”.

The controller may determine a first average value of the horizontal coordinate of the first lower left vertex and the horizontal coordinate of the second lower left vertex, and determine the first average value “356” as the horizontal coordinate of a third lower left vertex. The controller may determine a second average value of the vertical coordinate of the first lower left vertex and the vertical coordinate of the second lower left vertex, and determine the second average value “166” as the vertical coordinate of the third lower left vertex. The controller may determine a third average value of the first width information and the second width information, and determine the third average value “148” as a third width information. The controller may determine a fourth average value of the first height information and the second height information, and determine the fourth average value “148” as a third height information.

The seventh target image 603 may be processed according to the horizontal coordinate of the third lower left vertex, the vertical coordinate of the third lower left vertex, the third width information and the third height information included in the eighth parameter information, so as to obtain an eighth target image 602.

According to the embodiments of the present disclosure, in response to a detection of a switching instruction, the controller may determine the eighth parameter information according to the sixth parameter information and the seventh parameter information, and obtain the eighth target image according to the eighth parameter information, the sixth target image and the seventh target image, thereby increasing the number of target images without increasing the storage space. On this basis, the controller generates a fourth control instruction according to the eighth target image and the eighth parameter information of the eighth target image, and control the display module to display the eighth target image according to the fourth control instruction, thereby obtaining a smoother and finer display effect while reducing the number of pre-stored images.

According to the embodiments of the present disclosure, the controller 202 may determine a third region according to the sixth parameter information and the seventh parameter information, generate a fifth control instruction according to the sixth parameter information of the third region, the eighth target image and the eighth parameter information of the eighth target image, and control the display module 203, according to the fifth control instruction, to display the eighth target image and hide the display of at least one third sub-region in the third region in a frame displayed after switching from the sixth target image to the eighth target image.

According to the embodiments of the present disclosure, the fifth control instruction may refer to a control instruction for a complete process of the controller 202 controlling the display module 203 to switch from the sixth target image to the eighth target image. The frame displayed after switching from the sixth target image to the eighth target image may refer to the frame displayed after the display of the eighth target image is completed. A display content of the display picture on the display module 203 in the frame displayed after switching from the sixth target image to the eighth target image may be determined according to the processing speed of the controller 202. For example, the third region may include a third sub-region B1, a third sub-region B2, a third sub-region B3, and a third sub-region B4. In the frame displayed after switching from the sixth target image to the eighth target image, the eighth target image may be displayed, and the display of the third sub-region B1 may be hidden. Alternatively, in the frame displayed after switching from the sixth target image to the eighth target image, the eighth target image may be displayed, and the display of the third sub-region B1 and the third sub-region B2 may be hidden. Alternatively, in the frame displayed after switching from the sixth target image to the eighth target image, the eighth target image may be displayed, and the display of the third sub-region B1, the third sub-region B2 and the third sub-region B3 may be hidden. Alternatively, in the frame displayed after switching from the sixth target image to the eighth target image, the eighth target image may be displayed, and the third region may be hidden.

According to the embodiments of the present disclosure, upon a detection of switching from the sixth target image to a display of the eighth target image, the controller 202 may generate a fifth control instruction. The controller 202 may control the display module 203, according to the fifth control instruction, to display the sixth target image and hide the display of at least one third sub-region in the third region in the frame displayed after switching from the sixth target image to the eighth target image, so that the eighth target image may cover an overlapping region between the sixth target image and the eighth target image, and that the at least one third sub-region in the third region is not displayed on the display module 203 when the display module 203 displays the eighth target image. Hiding the display of the third sub-region may mean that a color of the third sub-region is consistent with a bottom color of the eighth target image or a predetermined background color. The bottom color of the eighth target image may be the predetermined background color.

For example, the controller 202 may control the display module 203, according to the fifth control instruction, to display the eighth target image in the frame displayed after switching from the sixth target image to the eighth target image, and call a background painting routine to set a pixel value of the at least one third sub-region to be consistent with a pixel value of the bottom color of the eighth target image or a pixel value of the predetermined background.

According to the embodiments of the present disclosure, since the controller controls the display module to display the eighth target image according to the fifth control instruction, the eighth target image may directly cover the overlapping region between the sixth target image and the eighth target image in the frame displayed after switching from the sixth target image to the eighth target image, so that the flickering process from bright to dark and then to bright during the switching from the sixth target image to the eighth target image may be effectively avoided, thereby improving the display effect and the user viewing experience.

According to the embodiments of the present disclosure, the sixth target image may be the first target image, and the seventh target image may be the second target image.
