The present disclosure relates to the field of image display technology, and particularly relates to a display method for inhibiting color separation and a field sequential display device.
Different from a conventional LCD (Liquid Crystal Display) screen, a backlight of a field sequential display device is composed of a plurality of partitions, each partition includes m×n pixels, and the backlight of each partition is composed of three types of LEDs (Light Emitting diodes), i.e., red, green, and blue LEDs, so that the backlight can display three colors and the brightness of each color can be adjusted. In addition, the pixels of the liquid crystal panel of the field sequential display device can display only gray scale images.
A field sequential color display is a novel color display mode, and each frame of image is divided into three sub-frames of R (red), G (green) and B (blue) for sequential scanning. Due to rotation of an eyeball, the RGB components of an image of a same point scanned according to the time sequence in one frame may fall on different positions on the retina, so that human eyes may perceive color separation of the image, i.e., a color separation phenomenon.
The field sequential display device may be applied to aspects of direct-view display, projection display, helmet display, and the like. When the field sequential display device serves as a VR screen, how to effectively inhibit the color separation phenomenon becomes a technical problem which is required to be solved urgently at present.
The present disclosure provides a display method for inhibiting color separation and a field sequential display device, for reducing differences between a plurality of frames, reducing perception of human eyes on subsequent frames, and eliminating the color separation phenomenon, through backlight brightness of different colors in the plurality of frames displayed sequentially.
In a first aspect, a display method for inhibiting color separation according to an embodiment of the present disclosure includes:

These and other aspects of the present disclosure will be more readily apparent in the following description of the embodiments.
In order to explain the technical solutions in the embodiments of the present disclosure more clearly, the drawings to be used in the description of the embodiments will be briefly described below. Apparently, the drawings in the following description are merely some embodiments of the present disclosure, and other drawings may be derived from these drawings by those skilled in the art without any creative labor.
To make the objects, technical solutions and advantages of the present disclosure more apparent, the present disclosure will be further described in detail below with reference to the drawings. Apparently, the described embodiments are merely some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure described herein without paying any creative effort shall be included in the protection scope of the present disclosure.
The term “and/or” in the embodiments of the present disclosure describes an association relationship between associated objects, and indicates that three relationships may exist. For example, A and/or B may indicate: A exists alone, A and B exist simultaneously, and B exists alone. The character “/” generally indicates that the associated objects before and after the character “/” are in an “or” relationship.
The term “refresh rate” in the embodiments of the present disclosure refers to the number of times the electron beam repeatedly scans an image on the screen. The higher the refresh rate is, the better the stability of the displayed image (picture) is. The refresh rate and the resolution are mutually restricted, and the performance of the display which achieves the high refresh rate under the high resolution is better.
The application scene described in the embodiments of the present disclosure is for more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not form a limitation on the technical solution according to the embodiment of the present disclosure. As those skilled in the art know, with the occurrence of a new application scene, the technical solution according to the embodiment of the present disclosure is also applicable to similar technical problems. In the description of the present disclosure, the meaning of “a plurality” is two or more, unless otherwise specified.
Embodiment 1, a conventional LCD (Liquid Crystal Display) screen generally includes a backlight and a panel (liquid crystal panel), where the backlight uses a white normally-bright mode, and the purpose of displaying a picture is achieved by controlling the deflection of the Liquid Crystal of the panel. Different from the conventional LCD screen, a backlight of a field sequential display device is composed of a plurality of partitions, each partition includes m×n pixels, and the backlight of each partition is composed of three types of LEDs (Light Emitting diodes), i.e., red, green, and blue LEDs, so that the backlight can display three colors and the brightness of each color can be adjusted. In addition, unlike the traditional LCD panel controlled by RGB three liquid crystal sub-pixels, a pixel of the field sequential panel has only one hole controlled by the liquid crystal, and can display only gray scale images.
A field sequential color display is a novel color display mode, which, compared with the conventional space color technology, avoids the use of color filters, has the advantages of high light source efficiency, high resolution, low cost and the like, and can be applied to aspects of direct-view display, projection display, helmet display and the like. However, in the field sequential color display, due to rotation of an eye, a viewer may often perceive color separation at an edge of a displayed object, i.e., a color separation phenomenon. In field sequential color display, a color separation phenomenon is caused by a field sequential display mechanism, where each frame of image is divided into three primary color fields to be displayed according to a time sequence, so that time difference exists in RGB components of the same image, when human eyeball rotates, a landing point of the RGB components on the retina is shifted, and human eyes may perceive the color separation.
For the VR display screen, the user can have an immersive sensation only when the frame refresh rate reaches 90 Hz, and when the field sequential screen serves as the VR screen, the refresh rate is required to reach 270 HZ in order to ensure the above effect. When a field sequential screen is used for displaying, an original frame of RGB image is required to be split into R, G, B three sub-frames for displaying, and as an eyeball moves, R, G, B three sub-frames at a certain position on screen fall at different positions of the retina of the human eye, respectively, so that the human perceives the color separation phenomenon. As shown in
In order to effectively inhibite the color separation phenomenon caused by the display mechanism of the field sequential display device, this embodiment provides a method of displaying while inhibiting color separation, which can be applied to a field sequential display device. The core idea is to split an original image into a plurality of frames for display, light up all colors of the backlight of the field sequential display device when any one frame of sub-image is displayed, and light up one color of the backlight each time when the sub-images of the rest frames are sequentially displayed, thereby effectively reducing the color and brightness difference value between a plurality of frames of sub-images during display, reducing the perception of human eyes on the color of the subsequent frames, and effectively inhibiting the color separation phenomenon.
It should be noted that the method of displaying while inhibiting color separation according to this embodiment is designed based on the display mechanism of the field sequential display device, may be applied to, but is not limited to the field sequential display device, and may also be applied to other display devices to eliminate the color separation phenomenon, which is not excessively limited in this embodiment.
In implementation, as shown in
As shown in
At the step 500, an original image to be displayed is acquired and a plurality of frames of sub-images each having a single channel are determined according to the original image, where the plurality of frames of sub-images include a plurality of first sub-images and a second sub-image determined according to the plurality of first sub-images.
In some embodiments, the acquired original image is a multi-channel image, and the original image includes, but is not limited to, an RGB image, an HSV image, a CMYK image, and the like, which is not excessively limited in the embodiments.
Taking an RGB image as an example, this embodiment splits the original image into a plurality of frames of sub-images each having a single channel, where each frame of sub-image is a gray scale image, and pixel values of each frame of sub-image are gray scale values of each gray scale image. Optionally, the number of the sub-images obtained by splitting in this embodiment is greater than the number of channels of the original image. In this embodiment, the first sub-image is obtained by splitting based on the number of channels of the original image, and the second sub-image is generated according to the plurality of first sub-images.
In some embodiments, the first sub-image and the second sub-image are determined by:
In implementation, the original image is split into N images each having a single channel according to the number N of channels of the original image, where N is greater than or equal to 3. Taking an RGB original image as an example, as shown in
In this embodiment, the first sub-image and the second sub-image are both gray-scale images, and the color original image is finally displayed through the colors of the backlight and the gray-scale images of respective frames of sub-images.
At the step 501, backlight data and pixel data of each frame of sub-image are determined, where the backlight data serves to represent a brightness of each color contained in a backlight assembly, and the pixel data serves to represent a pixel value of each pixel unit.
It should be noted that the backlight of the field sequential display device includes a plurality of partitions, each partition includes m×n pixels (units), the backlight of each partition is composed of three types of LEDs, i.e., red, green, and blue LEDs, and a brightness of the backlight is adjustable. The first sub-image and the second sub-image in this embodiment are used as the gray scale images input to the panel, the backlight data serves as the brightness of each color in the backlight of each gray scale image, and the pixel data represents the pixel value of each pixel in each gray scale image to be displayed. The backlight data of respective frames of sub-images are different from each other.
Since the backlight includes a plurality of partitions, the backlight data in this embodiment includes the backlight data of each partition, where the backlight of each partition may be different or the same, which is not excessively limited in this embodiment. The pixel data is not equivalent to the pixel value in each gray scale image, but the pixel data is determined based on the pixel value.
At the step 502, at least part of sub-images in the plurality of frames of sub-images are sequentially displayed in a preset sequence, according to the backlight data and the pixel data of the respective frames of sub-images, where the number of the displayed sub-images is greater than or equal to the number of channels of the original image, the backlight data of any one frame of sub-image serves to light up all colors contained in the backlight assembly, and the backlight data of the sub-images except the any one frame of sub-image serves to light up each time one color contained in the backlight assembly.
In some embodiments, when the at least part of sub-images in the plurality of frames of sub-images sequentially displayed in the preset sequence, according to the backlight data and the pixel data of the respective frames of sub-image, include the second sub-image, the backlight data of the displayed second sub-image serves to light up all colors contained in the backlight assembly, and the backlight data of the sub-images except the second sub-image serves to light up each time one color contained in the backlight assembly.
In implementation, when the sub-images corresponding to respective frames of original images are sequentially displayed according to a predetermined cyclic display sequence, for example, according to XRG-BXR-GBX-RGB, the backlight data of the second sub-image corresponding to the displayed first frame of original image serves to light up all colors of the backlight assembly, and the backlight data of the first sub-images corresponding to the displayed first frame of original image serves to light up each time one color contained in the backlight assembly; the backlight data of the second sub-image corresponding to the displayed second frame of original image serves to light up all colors of the backlight assembly, and the backlight data of the first sub-images corresponding to the displayed second frame of original image serves to light up each time one color contained in the backlight assembly; similarly, the backlight data of the second sub-image corresponding to the displayed third frame of original image serves to light up all colors of the backlight assembly, and the backlight data of the first sub-images corresponding to the displayed third frame of original image serves to light up each time one color contained in the backlight assembly.
In some embodiments, it may alternatively provide the following manner for eliminating the color separation phenomenon:
It should be noted that, in this embodiment, the number of frames of the sub-images determined according to the original image is greater than the number of channels of the original image. Therefore, when displaying, one display mode is to display all the sub-images, and the other mode is to display part of the sub-images, and finally display all the sub-images in a cycle period through a cycle display mode. The specific display modes are described below.
In the first display mode, one frame of original image corresponds to displaying three frames of sub-images.
In implementation, each time an RGB original image is displayed, three frames of sub-images of the original image are displayed. Taking an original image being an RGB image as an example, pixel values of R, G, B channels of the original image are extracted, to obtain three first sub-images, namely an image R, an image G and an image B; a second sub-image is generated according to a minimum pixel value of the image R, the image G and the image B at a corresponding position.
When a plurality of frames of original images are acquired, at least part of sub-images in a plurality of frames of sub-images are sequentially displayed according to a preset sequence in the following way, where every four frames of original images are displayed as a cycle period.
When every four frames of original images are displayed, three sub-images of each frame of original image are sequentially displayed according to the following cyclic sequence:
It should be noted that, in this embodiment, the display is performed in the sequence of the second sub-image (assumed to be X), the image R, the image G, and the image B, every three sub-images are displayed once, and then three sub-images are continuously displayed in the sequence of shifting one sub-image to the left, and the sequence of the cyclic display is XRG-BXR-GBX-RGB. Based on this principle of display, the display in other sequences also belongs to the protection scope of the present disclosure, for example, the cyclic display is performed in the sequence of the image R, the image G, the image B, and the second sub-image, and the sequence of the cyclic display is RGB-XRG-BXR-GBX, where the cyclic display of the sub-images can be completed every four frames of original images. Displaying three sub-images of the original image each time further includes other display sequences, for example, displaying every three sub-image, and then continuously displaying three sub-images in a sequence of shifting one sub-image to the right, or displaying in other defined manners, which all belong to the protection scope of the present disclosure, and are not listed one by one herein.
It should be noted that, when the field sequential display device serves as the VR screen, since the user can have an immersive sensation only when the frame refresh rate reaches 90 Hz, if the field sequential display device displays one frame of original image with three frames of sub-images, in order to ensure the VR display effect, the backlight and the panel of the field sequential display device are required to operate at the refresh rate of 3×90=270 frames.
In the second display mode, one frame of original image corresponds to displaying four sub-images.
In implementation, each time an RGB original image is displayed, four frames of sub-images of the original image are displayed. Taking an original image being an RGB image as an example, pixel values of R, G, B channels of the original image are extracted to obtain three first sub-images, namely an image R, an image G and an image B; a second sub-image is generated according to a minimum pixel value of the image R, the image G and the image B at a corresponding position.
All sub-images in a frame of original image are sequentially displayed according to a preset sequence as follows:
It should be noted that, in this embodiment, the display is performed in the sequence of the second sub-image, the image R, the image G, and the image B. Based on this principle of display, the display in other sequences also belongs to the protection scope of the present disclosure. For example, the display is performed in a sequence of the image R, the image G, the image B, and the second sub-image, or in other display sequences, which are not listed one by one herein.
It should be noted that, when the field sequential display device serves as the VR screen, since the user can have an immersive sensation only when the frame refresh rate reaches 90 Hz, if the field sequential display device displays one frame of original image with four frames of sub-images, in order to ensure the VR display effect, the backlight and the panel of the field sequential display device are required to operate at the refresh rate of 4×90=360 frames.
In some embodiments, the backlight data represents a brightness value of the backlight in each partition. In the at least part of sub-images to be displayed, the brightness values of three colors contained in the backlight of the first frame of sub-image are the same, and the brightness value of one color contained in the backlight of each of the subsequent frames of sub-images may be calculated according to the pixel values of the sub-images. Alternatively, the backlight data in this embodiment is a preset value.
As can be seen from the manner of displaying a plurality of frames of sub-images, the first frame of displayed sub-image of the original image may be the first sub-image or the second sub-image, which is determined according to practical requirements.
In some embodiments, when calculating the backlight data of each frame of sub-image of the current frame of original image, the backlight data of each frame of sub-image of a previous frame of original image may be referred to, to improve the viewing experience as much as possible by reducing the color difference value between a plurality of frames of original images. If the current frame of original image to be displayed is the first frame of original image, the backlight data in the first frame of original image may be set as a preset value without referring to a previous frame of original image, or the backlight data may be determined according to the pixel values in respective frames of sub-images of the first frame of original image.
In some embodiments, when a plurality of frames of original images are acquired and it is determined that a current frame of original image to be displayed is not a first frame of original image, backlight data of a first frame of sub-image in the at least part of sub-images to be displayed is determined by the following steps (1) and (2).
(1) When it is determined that the first frame of sub-image is the first sub-image, determining the backlight data of the first frame of sub-image in each partition in the backlight assembly, according to a mean value of the backlight data of the first sub-image of the current frame of original image in the partition and the backlight data of the first sub-image of a previous frame of original image in the partition.
The backlight data of various positions of each partition is equal. In implementation, the backlight data of each partition of the first sub-image of the current frame of original image in the backlight assembly and the backlight data of the partition of the first sub-image of the previous frame of original image are calculated, then the two backlight data in the same partition are averaged to obtain the backlight data of the partition, and the backlight data serves as the backlight data of the first frame of sub-image.
(2) When it is determined that the first frame of sub-image is the second sub-image, determining the backlight data of the first frame of sub-image in each partition in the backlight assembly, according to a mean value of the backlight data of the second sub-image of the current frame of original image in the partition and the backlight data of the second sub-image of the previous frame of original image in the partition.
In implementation, the backlight data of each partition of the second sub-image of the current frame of original image in the backlight assembly and the backlight data of the partition of the second sub-image of the previous frame of original image are calculated, then the two backlight data in the same partition are averaged to obtain the backlight data of the partition, and the backlight data serves as the backlight data of the first frame of sub-image.
In some embodiments, the backlight data of the first sub-image corresponding to each frame of original image is calculated by the following method, where the first sub-image of the current frame of original image (not the first frame of original image), the first sub-image of the previous frame of original image, and the first sub-image of the first frame of original image all can be calculated by the following method to obtain the respective backlight data.
The following steps are executed for a first sub-image and a second sub-image in each frame of original image:
In implementation, the difference value between the pixel values of the first sub-image and the second sub-image at the corresponding position in each partition is calculated, the maximum difference value between the pixel values in the partition (i.e., the maximum difference value) is screened out, and then the maximum difference value in the partition serves as the backlight data (i.e., the backlight brightness) of the partition.
In some embodiments, the backlight data of the second sub-image corresponding to each frame of original image is calculated by the following method, where the second sub-image of the current frame of original image (not the first frame of original image), the second sub-image of the previous frame of original image, and the second sub-image of the first frame of original image all can be calculated by the following method to obtain the respective backlight data.
The following step is executed for a second sub-image in each frame of original image:
In implementation, the backlight data of the second sub-image is calculated with the maximum pixel value of the second sub-image in each partition, and the maximum pixel value (i.e. the maximum value) in the partition is taken as the backlight data (i.e. the backlight brightness) of the corresponding partition.
In some embodiments, when calculating the pixel data of each sub-image corresponding to the current frame of original image, calculation may be performed according to only respective frames of sub-images of the current frame of original image, or may also refer to respective frames of sub-image of a previous adjacent frame of original image, which is not excessively limited in the embodiments.
In some embodiments, for each frame of original image, the pixel data of the first sub-image corresponding to the frame of original image may be determined by:
In implementation, the difference value between the pixel values of the first sub-image and the second sub-image of the frame of original image at a corresponding position (a position of the same pixel) is calculated first. That is, the difference value between the pixel values of the first sub-image and the second sub-image is calculated at each pixel position of the original image, and at this time, each pixel position corresponds to one difference value. Then, backlight data of the partition in the backlight assembly, where the pixel point on each pixel position is located, is calculated. Finally, the ratio of the difference value at each pixel position to the backlight data of the corresponding partition is calculated, to obtain the ratio at each pixel position, and the ratio at each pixel position is determined as the pixel data of the first sub-image.
In some embodiments, for each frame of original image, the pixel data of the second sub-image corresponding to the frame of original image may be determined by:
In implementation, each pixel value of the second sub-image and the backlight data of the partition in the backlight assembly corresponding to the pixel value are determined, the ratio of each pixel value to the backlight data of the corresponding partition is calculated, and the ratio at each pixel position is determined as the pixel data of the second sub-image.
In some embodiments, when a plurality of frames of original images are acquired and it is determined that a current frame of original image to be displayed is not a first frame of original image, the pixel data of a first frame of sub-image may be calculated with reference to the pixel data of a previous frame of sub-image, and may be determined by the following methods 1 and 2.
Method 1, determining the first frame of sub-image as a first sub-image; and
In some embodiments, when it is determined that the first frame of sub-image is the first sub-image, the pixel data of the first frame of sub-image is determined specifically by:
In implementation, firstly, a difference value between pixel values of the first sub-image and the second sub-image of the current frame of original image at a corresponding position is calculated, where each pixel position of the current frame of original image corresponds to one difference value. Then, a mean value of backlight data of the first sub-image of the current frame of original image in each partition in a backlight assembly and backlight data of the first sub-image of a previous frame of original image at the partition is calculated. Finally, the pixel data of each pixel position is determined, according to the ratio of the difference value corresponding to the pixel position to the mean value of the partition corresponding to the pixel position. Namely, the ratios corresponding to respective pixel positions are determined as the pixel data of the first frame of sub-image.

Finally, the ratio of the difference value corresponding to each pixel position to the maximum difference value of the partition corresponding to the pixel position is calculated, and the ratios corresponding to respective pixel positions are taken as the pixel data of the first sub-image.
In some embodiments, the pixel data of the second sub-image may be alternatively determined by:
