The present disclosure relates to a display panel and its driving method and driving device.
With the unceasing development of display technology, requirements on a display resolution of a display panel also become higher and higher. According to the display resolution, display panels can be divided into Ultra-High-Definition (UHD) display panels, Full-High-Definition (FHD) display panels, and High-Definition (HD) display panels. However, a majority of module products adopt an unchanged pixel structure, that is, the resolution cannot be changed. For example, if a display panel is an Ultra-High-Definition display panel, and a resolution of an image to be displayed is relatively low but still is within a range of Ultra-High-Definition display resolution, then when the image is displayed on the Ultra-High-Definition display panel, before displaying, it needs to increase the resolution of the image to a value which is the same with that of the display panel.
Therefore, in the module products, the resolution of the display panel cannot be changed. The display panel can only carry out Ultra-High-Definition (UHD) displaying, or Full-High-Definition (FHD) displaying, or High-Definition (HD) displaying. Thus, in some cases, for example, when displaying a video, the display panel is always in an Ultra-High-Definition display state, but cannot change the display resolution flexibly, increasing display power consumption of the display panel.
In a summary, the display panels known to the inventor cannot selectively reduce the display resolution of the display panel, and increase the display power consumption of the display panel.

In order to make the objects, technical solutions, and advantages of the present application to be more apparent, hereinafter, the present disclosure will be described in detail in conjunction with the drawings. Obviously, the described embodiments are merely parts of the embodiments of the present disclosure, rather than all of the embodiments thereof. All the other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts fall into the protection scope of the present disclosure.
It should be noted that, in the embodiment of the present disclosure, setting at least one switching unit between different gate lines means that one switching unit may be set between a pair of two adjacent rows of gate lines in the display panel, or that one switching unit may be set respectively between several pairs of two adjacent rows of gate lines, or that one switching unit may be set between each pair of two adjacent rows of gate lines. However, as to how many switching units are to be set, the present disclosure makes no limitations. In addition, the switching unit is configured to control two rows of gate lines to be conducted, to which the switching unit are connected, so that the two rows of gate lines perform scanning concurrently. And thus, the switching unit may be set only between two adjacent rows of gate lines.
When one switching unit is switched on, the two rows of gate lines connected to the switching units are conducted, so that the two rows of gate lines concurrently scan subpixel cells to which the two rows of gate lines correspond. According to the switching on state of the switching unit, when an image signal is inputted to the data lines, it only needs to input to one data line to which the two rows of gate lines correspond. Inputting to one data line to which the two rows of gate lines correspond may be that the image signal is inputted to one of the first two data lines if the first two rows of gate lines are conducted.
In the display panel according to the embodiment of the present disclosure, at least one switching unit is provided between different gate lines to control whether at least two rows of gate lines are conducted. The switching units are connected one by one to the second output terminals of the driving control module to receive a control signal outputted by the driving control module for controlling whether to switch on the switching unit; the data lines in the display panel are connected one by one to the second output terminals of the driving control module to receive an image signal outputted by the driving control module. When the switching unit receives the control signal outputted by the driving control module via the first output terminals for controlling the switching unit to be switched on, the switching unit is switched on, so that two rows of gate lines connected to the switching unit perform scanning simultaneously; according to the switching on state of the switching unit, the driving control module outputs the image signal to the data lines to which the two rows of gate lines correspond, so that the display resolution of the display panel is reduced, and the display power consumption of the display panel is decreased.
Referring to
By means of providing a switching unit between each pair of two adjacent rows of gate lines, and based on switching on of the switching unit, the display resolution of the display panel is reduced to a larger extent, and the display power consumption of the display panel is decreased.
Referring to
It should be noted that the switching unit is used to make the two adjacent rows of gate lines conducted. Therefore, the switching unit in the present disclosure is not limited to the thin film transistor. Any device capable of making the two rows of gate lines connected to the switching unit conducted via the control signal belongs to the protection scope of the present disclosure.
The driving control module 14 is configured to:
It should be noted that the driving control module in the embodiment of the present disclosure is a driving IC (DIC) or a Gate IC for driving a gate. Of course, in the embodiment of the present disclosure, determining a display mode to which the resolution of the image to be displayed corresponds based on a resolution of an image to be displayed which is transmitted by a signal source may be executed by the driving IC or the Gate IC or an application processor (AP), the present disclosure makes no limitation thereto.
The image to be displayed in the embodiment of the present disclosure refers to an image that is to be displayed by the panel but has not yet been displayed, and the image signal refers to image content that needs to be displayed on the display panel of the image to be displayed.
By controlling the switching unit and the data lines by the driving control module, the display resolution of the display panel is reduced, and the display power consumption of the display panel is decreased. The driving control module determines, based on a resolution of an image to be displayed which is transmitted from a signal source, a display mode to which the resolution of the image to be displayed corresponds, and then determines, based on the display mode, switching units that need to be switched on and switched off, and outputs a control signal to each switching unit, and outputs an image signal of the image to be displayed to a corresponding data line based on an on/off state of the switching unit.
The driving control module 14 is further configured to:
In the embodiment of the present disclosure, the static display mode may be a mode for displaying static information such as a static picture or text, and the dynamic display mode may be a mode for displaying information such as a dynamic picture or a video.
The driving control module in the display panel according to the embodiment of the present disclosure can be further used to: receive a voltage signal of an image to be displayed which is transmitted by a signal source; determine an image display mode of the image to be displayed based on the voltage signal; when the image display mode is determined as a static display mode, based on a resolution of the image to be displayed, the driving control module determines the switching unit that needs to be switched off, and outputs a control signal for controlling a corresponding switching unit to be switched off to the corresponding switching unit, and outputs an image signal to a corresponding data line based on the state of the switching uint. Thus, when the image display mode of the image to be displayed is the static display mode, by switching off the switching unit, the display resolution in the display panel can change from low to high so that the resolution of the image to be displayed during static displaying is increased and user experience is improved.
The driving control module 14 is further configured to:
When the driving control module determines that the image display mode is a dynamic display mode, a frame frequency for image transmission is increased, so that fluency when the display panel displays a dynamic image such as video is improved, and user experience is improved.
To sum up, in the display panel according to the embodiment of the present disclosure, at least one switching unit is provided between different gate lines to control whether at least two rows of gate lines are conducted; each switching unit is connected one by one to first output terminals of the driving control module to receive a control signal outputted by the driving control module for controlling whether to switch on the switching unit; each data line in the display panel is connected one by one to the second output terminals of the driving control module to receive an image signal outputted by the driving control module. When the switching unit receives a control signal outputted by the driving control module via the first output terminals for controlling the switching unit to be switched on, the switching unit is switched on, so that two rows of gate lines connected to the switching unit perform scanning simultaneously, and meanwhile, according to the switching on state of the switching unit, the driving control module outputs the image signal to the data lines to which the two rows of gate lines correspond, so that the display resolution of the display panel is reduced, and the display power consumption of the display panel is decreased. In addition, the driving control module further receives a voltage signal of an image to be displayed which is transmitted by a signal source, and determines an image display mode of the image to be displayed based on the voltage signal. When the image display mode is determined as a static display mode, based on a resolution of the image to be displayed, the driving control module determines the switching unit that needs to be switched off, and outputs a control signal for controlling a corresponding switching unit to be switched off to the corresponding switching unit, and outputs an image signal to a corresponding data line based on the state of the switching unit. When the image display mode of the image to be displayed is the static display mode, the frame frequency is improved for transmitting the image. Thus, when the image display mode of the image to be displayed is determined as the static display mode, by switching off the switching unit, the display resolution in the display panel changes from low to high, so that the resolution of the image to be displayed during static displaying is increased and user experience is improved, and when it is determined that the image display mode of the image to be displayed is a dynamic display mode, a frame frequency for image transmission is increased, so as to improve fluency when the display panel displays a dynamic image such as video. Therefore, the display panel is capable of automatically determining the image display mode of the image to be displayed, automatically decreasing the resolution of the image to be displayed or automatically increasing the resolution of the image to be displayed, so that, based on the image display mode of the to be-displayed image, resolution of the image in the static display mode can be increased, or fluency of the image in the dynamic display mode can be improved and in turn user experience is improved.
In step S401, a resolution of the image can calculated based on received image information of an image to be displayed which is transmitted from a signal source so that a resolution of image to be displayed transmitted from the signal source is determined.
In step S402, the display mode may be an ultra-high-definition display mode, a full-high-definition display mode, or a high-definition display mode.
In the embodiment of the present disclosure, a resolution to which the ultra-high-definition display mode corresponds may be 2160*3840, wherein 3840 is the number of pixels in rows, and 2160 is the number of pixels in columns; a resolution to which the ultra-high-definition display mode corresponds may be 1080*1920, wherein 1920 is the number of pixels in rows, and 1080 the number of pixels in columns; and a resolution to which the high-definition display mode corresponds may be 720*1280, wherein 1280 is the number of pixels in rows, and 720 is the number of pixels in columns.
Further, in step S402,
In the embodiment of the present disclosure, the display panel may be an ultra-high-definition display panel. For example, the resolution of the display panel may be 2160*3840, wherein 3840 is the number of pixels in rows and 2160 is the number of pixels in columns. In this case, a maximum resolution of the display panel is 2160*3840; a half resolution of the maximum resolution is 1080*1920, wherein 1920 is the number of pixels in rows and 1080 is the number of pixels in columns; and one third resolution of the maximum resolution is 720*1280, wherein 1280 is the number of pixels in rows and 720 is the number of pixels in columns.
Of course, for the full-high-definition display panel whose maximum resolution is 1080*1920, the structure and driving method of the display panel in the embodiment of the present disclosure are also applicable. The display panel in the embodiment of the present disclosure may also be an ultra-high-definition display panel or a full-high-definition display panel, and the present application makes no limitations thereto.
After it is determined that the display mode to which the resolution of the image to be displayed corresponds is the ultra-high-definition display mode, the method further comprises:
After it is determined that the display mode to which the resolution of the image to be displayed corresponds is the full-high-definition display mode, the method further comprises:
The user instruction message for changing the display mode into the high-definition display mode may be provided to the user for selecting in form of a pop-up interface in the display panel, and the user instruction message may be either selected by the user during the display process, or selected by the user before the display panel displays the image to be displayed. The present disclosure makes no limitations to the form of and time for providing the user instruction message.
The resolution of the image to be displayed may be decreased when being displayed as needed. For example, when the image to be displayed is a dynamic video, the resolution of the image to be displayed may be decreased properly, so as to reduce display power consumption of the display panel. If the resolution of the panel to be displayed is 2160*3840, the resolution may be decreased to 1080*1920 or 720*1280 by the driving IC or the application processor based on algorithms. And then the display resolution of the display panel is reduced through a control signal transmitted by the driving IC or a control signal for controlling switched on/off of the switching unit transmitted by the Gate IC, and display power consumption for displaying the dynamic video is decreased.
Step S403 may comprises:
In a case where the switching units are N-type thin film transistors, a signal controlling the switching units to be switched on is a high level, and a signal controlling the switching units to be switched off is a low level. In a case where the switching units are P-type thin film transistors, a signal controlling the switching units to be switched on is a low level and a signal controlling the switching units to be switched off is a high level.
Next, the method will be described in more details in conjunction with

Referring to
In step S505, it is determined whether a user instruction message for changing the display mode into the high-definition display mode is received; if yes, step S506 is executed, otherwise step S507.
In step S506, the first and second switching units within each group of switching units are controlled to be switched on and the third switching unit within each group of switching units is controlled to be switched off, and an image signal of the image to be displayed is transmitted to the first, fifth, and ninth data lines within each group of data lines.
Each group of switching units includes three adjacent switching units in each column, wherein the switching units included by different groups may be different. Each group of data lines includes every nine adjacent data lines, and the date lines included by different groups may be different.
It should be noted that the purpose of building a group of data lines by nine adjacent data lines is to ensure the finally retained data lines to be a complete RGB structure, as well as a ratio between the output signal terminals and the resolution aspect ratios which meets the three resolutions of the ultra-high-definition display mode, the full-high-definition display mode and the high-definition display mode.
Referring to
In step S507, each switching unit is controlled to be switched off, and the image signal of the image to be displayed is transmitted to each data line.
Referring to
In step S508, in a case where the display mode is the full-high-definition display mode, it is determined whether a user instruction message for changing the display mode into the high-definition display mode is received; if yes, step S506 is executed, otherwise step S504 is executed.
In step S509, the first and second switching units within each group of switching units are controlled to be switched on and the third switching unit within each group of switching units is controlled to be switched off, and an image signal of the image to be displayed is transmitted to the first, fifth, and ninth data lines within each group of data lines, wherein the switching on states are the same with those in step S506.
According to the above, when the display mode of the image to be displayed is the ultra-high-definition display mode, the display mod of the image can be reduced to the full-high-definition display mode or the high-definition display mode as required, and a reduction of the display resolution of the display panel can be achieved by switching on the switching units, so as to reduce the display resolution of the image to be displayed in the display panel as well as the display power consumption of the display panel. When the display mode of the image is the full-high-definition display mode, the display mode of the image can be reduced to the high-definition display mode as required, and a reduction of the display resolution of the display panel can be achieved by switching on the switching units, so as to reduce the display resolution of the image to be displayed in the display panel as well as the display power consumption of the display panel.

In this embodiment, the two adjacent frames may be the frame when preparing the voltage signal for transmitting the image to be displayed and a previous frame of this frame.
Determining the current image display mode based on a voltage signal of an image to be displayed of two adjacent frames may comprise:
It should be noted that, when determining the image display mode, the comparison may also be performed based on the voltage signal of the image to be displayed and a voltage of an already displayed image in the previous frame or previous two frames or previous more frames. In other words, the present disclosure is not limited to a comparison only with the voltage signal of the previous frame.
In addition, step S703 may comprise:
For example, when it is determined that the image display mode is the static display mode, in order to enhance user experience, the resolution of the image to be displayed may be increased to a resolution to which the full-high-definition display mode corresponds or to a resolution to which the ultra-high-definition display mode corresponds. For example, if the resolution of the image to be displayed is 720*1280, the resolution of the image to be displayed may be increased to 1080*1920 or 2160*3840 by algorithms.
Referring to the display panel shown in
As another example, in order to increase the resolution of the image to be displayed to 2160*3840, the first output terminals of the control driving module can be controlled to output a control signal for controlling each of K1, K2, K3, K4 . . . K3837, K3838, K3839, K3840 to be switched off, and meanwhile, the image signal of the image to be displayed is transmitted to each gate line.
By the above driving method, the image display mode of the image to be displayed is determined according to the voltage signal of the image to be displayed. Thus, when it is determined that the display mode of the image to be displayed is the static image mode, the switching unit that needs to be switched off are determined based on the resolution of the image, and the control signal for controlling to switch off the switching unit is transmitted to the corresponding switching unit, and meanwhile the image signal is transmitted to the corresponding data line based on the state of the switching unit, so that when the display mode of the image to be displayed is the static image mode, through the switching off of the switching unit, the display resolution in the display panel changes from low to high, and accordingly, the resolution of the image to be displayed during static displaying is increased, user experience is improved. The driving method further comprises, when the image display mode of the image to be displayed is a dynamic display mode, increasing a frame frequency for image transmission so as to improve fluency when the display panel displays a dynamic image such as video. Thus, by means of automatically determining the image display mode of the image to be displayed, automatically decreasing the resolution of the image to be displayed or automatically increasing the resolution of the image to be displayed, based on the image display mode of the to be-displayed image, either resolution of the image in the static display mode is increased, or fluency of the image in the dynamic display mode is improved, so that user experience is improved.

Determining the current image display mode based on a voltage signal of an image to be displayed of two adjacent frames may comprise:
It should be noted that, when determining the image display mode, the comparison may also be performed based on the voltage signal of the image to be displayed and a voltage of an already displayed image in the previous frame or previous two frames or previous more frames. In other words, the present disclosure is not limited to a comparison only with the voltage signal of the previous frame.
In the embodiment of the present disclosure, the static display mode may be an image in a case where the display panel will not change such as in a state of reading or a static picture, and the dynamic display mode may be an image in a case where the display panel changes constantly such as in a state of a dynamic picture or a video.
In addition, step S803 may comprise:
For example, when it is determined that the image display mode is the static display mode, in order to enhance user experience, the resolution of the image to be displayed may be increased to a resolution to which the full-high-definition display mode corresponds or to a resolution to which the ultra-high-definition display mode corresponds. For example, if the resolution of the image to be displayed is 720*1280, the resolution of the image to be displayed may be increased to 1080*1920 or 2160*3840 by algorithms.
Referring to the display panel shown in
As another example, in order to increase the resolution of the image to be displayed to 2160*3840, the first output terminals of the control driving module can be controlled to output a control signal for controlling each of K1, K2, K3, K4 . . . K3837, K3838, K3839, K3840 to be switched off, and meanwhile, the image signal of the image to be displayed is transmitted to each gate line.
The driving method may further comprise:

According to the above, in the display panel according to the embodiment of the present disclosure, at least one switching unit is provided between different gate lines to control whether at least two rows of gate lines are conducted. Each switching unit is connected one by one to second output terminals of the driving control module to receive a control signal outputted by the driving control module for controlling whether to switch on the switching unit; and each data line in the display panel is connected one by one to the second output terminals of the driving control module to receive an image signal outputted by the driving control module. When the switching unit receives the control signal outputted by the driving control module via the first output terminals for controlling the switching unit to be switched on, the switching unit is switched on, so that two rows of gate lines connected to the switching unit perform scanning simultaneously; according to the switching on state of the switching unit, the driving control module outputs the image signal to the data lines to which the two rows of gate lines correspond, so that the display resolution of the display panel is reduced, and the display power consumption of the display panel is decreased. In addition, the driving control module further receives a voltage signal of an image to be displayed which is transmitted by a signal source, and determines an image display mode of the image to be displayed based on the voltage signal.

Thus, the display panel can automatically determining the image display mode of the image to be displayed, automatically decreasing the resolution of the image to be displayed or automatically increasing the resolution of the image to be displayed. And thus, based on the image display mode of the image to be displayed, either resolution of the image in the static display mode is increased, or fluency of the image in the dynamic display mode is improved, so that user experience is improved.
