Description

Technical Field

[0001] The embodiments of the present disclosure relate to, but are not limited to, the field of display technology, and in particular to a display method of a display panel, a display control device, and a display device. Background Art

[0002] The resolution of a display refers to the number of pixels that make up the display screen. For example, a 4K display refers to a display device with a 4K (4096×2160) resolution, that is, there are 4096 pixels horizontally and 2160 pixels vertically on the display screen. Image resolution refers to the number of pixels in an image, such as 2K (2048×1080), 4K (4096×2160), 8K (7680×4320) and other resolution images.

[0003] When the image resolution is higher than the monitor resolution, there are two display methods. One is partial display, that is, the number of pixels displayed is the same as the number of pixels on the screen. In this case, only a part of the image can be seen, and the image can be moved up, down, left, and right to see the complete content. The other method is to display the complete image on the screen. In this case, the pixels of the image will be compressed. For example, an 8K resolution image will delete some pixels to be displayed on a 4K resolution screen. Although the complete image content can be seen at this time, some pixels will be lost in the details, so the picture details are lost, which seriously affects the user's viewing experience.

[0041] The display method of the display panel of the embodiment of the present disclosure divides the pixel units on the display panel into odd display groups and even display groups, so that the odd display groups display odd-numbered row images and the even display groups display even-numbered row images, thereby realizing sub-pixel time-division multiplexing, thereby improving the resolution display effect of the display panel, so that the display panel can display clearer and more detailed images.

[0042] Figure 1 1 is a schematic diagram of a display panel provided by an exemplary embodiment of the present disclosure. The display panel 10 may include: M*N pixel units P, each pixel unit P includes one or more first sub-pixels P1 arranged along a first direction D1, one or more second sub-pixels P2 arranged along the first direction D1, and one or more third sub-pixels P3 arranged along the first direction D1, the first sub-pixels P1, the second sub-pixels P2, and the third sub-pixels P3 are arranged along a second direction D2, and the first direction D1 and the second direction D2 intersect.

[0043] In some exemplary embodiments, the first sub-pixel P1 may be a red sub-pixel (R) that emits red light, the second sub-pixel P2 may be a green sub-pixel (G) that emits green light, and the third sub-pixel P3 may be a blue sub-pixel (B) that emits blue light. In other exemplary embodiments, the first sub-pixel P1, the second sub-pixel P2, and the third sub-pixel P3 may be sub-pixels of other colors, or the number of sub-pixels of different colors included in each pixel unit may exceed 3, such as 4 sub-pixels of different colors, which is not limited in the present disclosure.

[0044] In an exemplary embodiment, the shape of the sub-pixel may be a rectangle, a diamond, a pentagon, a hexagon, or the like.

[0045] In some exemplary embodiments, the first sub-pixel P1, the second sub-pixel P2 and the third sub-pixel P3 may be arranged in a vertical parallel manner to form an RGB pixel arrangement. In other exemplary embodiments, the plurality of sub-pixels may be arranged in a square, a diamond or in a horizontal parallel manner, which is not limited in the present disclosure.

[0046] In some exemplary embodiments, the first direction D1 may be an extension direction (row direction) of a scan signal line in the display area, and the second direction D2 may be an extension direction (column direction) of a data line in the display area. The first direction D1 and the second direction D2 intersect, and exemplary, the first direction D1 and the second direction D2 may be perpendicular to each other.

[0047] 3D display has gradually become popular in recent years. The main principle of 3D display technology is to make the viewer's left eye and right eye receive different images respectively. The two images of the left and right eyes are analyzed and overlapped by the human brain, so that the viewer can perceive the layering of the image and produce a sense of three-dimensionality. Among them, naked-eye 3D display technology is a hot research topic in 3D display technology.

[0048] Naked-eye 3D display technology mainly includes holographic 3D display technology, volumetric 3D display technology, free stereoscopic 3D display technology, etc. Among them, free stereoscopic 3D display technology has been considered to be the fastest naked-eye 3D display technology for commercialization because it can achieve dynamic, colorful and wide-angle three-dimensional display effects. Free stereoscopic 3D display technology includes naked-eye 3D display technology based on geometric optics, such as cylindrical lens array technology, parallax barrier technology, microlens array technology, etc. This type of technology is mainly based on the principles of rectilinear propagation, reflection, and refraction of light. Through structural design, the emission direction of each pixel in the display panel is changed, and each perspective image is projected at a different viewpoint position, so that the left and right eyes of a person can see different perspective images, forming a sense of three-dimensional vision.

[0049] Currently, naked-eye 3D displays generally use multi-view technology, that is, multiple viewpoints are set so that users can see the 3D display image at multiple locations. Figure 2 As shown, a vertically arranged grating structure 20 is provided in front of the display panel 10, and the display panel 10 is used to display four viewpoint images (1, 2, 3 and 4). The viewer can see the 3D image at multiple positions, thereby providing the viewer with greater viewing freedom.

[0050] The display panel of the embodiment of the present disclosure changes the conventional horizontally arranged RGB pixels into vertically arranged RGB pixels. At the same time, each pixel unit has multiple same-color display sub-pixels in the row direction, which can be controlled separately (such as Figure 1 As shown, each pixel unit has 4 same-color display sub-pixels in the row direction that can be controlled separately, and there can actually be 16 or more. For example, the number of same-color display sub-pixels in each pixel unit P can be an even number). The advantage of this display arrangement is that it can achieve naked-eye 3D multi-viewpoint display with a resolution of M*N by fitting the vertically arranged grating structure (4 same-color display sub-pixels realize 4-viewpoint display, and 16 same-color display sub-pixels realize 16-viewpoint display), where M is the number of rows of pixel units and N is the number of columns of pixel units. At the same time, the optical properties of the grating structure are controlled by a voltage control circuit, and the 2D and 3D display modes can be switched. When 2D display is required, each pixel unit P can display a 2D picture. At this time, multiple same-color display sub-pixels in the same pixel unit P are input with the same grayscale value, so that the viewer can see the 2D picture with a resolution of M*N.

[0051] Image resolution refers to the number of pixels in an image, such as 2K (2048 × 1080), 4K (4096 × 2160), 8K (7680 × 4320) and other resolution images. Since the current image resolution is usually large, the display panel resolution is often lower than the image resolution.

[0052] When the image resolution is higher than the monitor resolution, there are two display methods. One is partial display, that is, the number of pixels displayed is the same as the number of pixels on the screen. In this case, only a part of the image can be seen, and the image can be moved up, down, left, and right to see the complete content. The other method is to display the complete image on the screen. In this case, the pixels of the image will be compressed. For example, an 8K resolution image will delete some pixels to be displayed on a 4K resolution screen. Although the complete image content can be seen at this time, some pixels will be lost in the details, so the picture details are lost, which seriously affects the user's viewing experience.

[0053] The present disclosure provides a display method of a display panel, such as Figure 3 As shown, the display panel includes M*N pixel units P, each pixel unit P includes a plurality of first sub-pixels P1 arranged along a first direction D1, a plurality of second sub-pixels P2 arranged along the first direction D1, and a plurality of third sub-pixels P3 arranged along the first direction D1. The first sub-pixels P1, the second sub-pixels P2, and the third sub-pixels P3 are arranged along a second direction D2, and the first direction D1 intersects the second direction D2. The display method includes:

[0054] Acquire multiple frames of images to be displayed, wherein one of two adjacent frames of images to be displayed is an odd-numbered row image, and the other is an even-numbered row image, the resolution of the odd-numbered row image is M*2N, and the resolution of the even-numbered row image is M*2N or (M-1)*2N;

[0055] The odd display group displays an odd-numbered row image, and the even display group displays an even-numbered row image, the odd display group includes M*2N odd display units, the even display group includes (M-1)*2N even display units, the i-th row of odd display units includes the first sub-pixel in the i-th row of pixel units, the second sub-pixel in the i-th row of pixel units, and the third sub-pixel in the i-th row of pixel units, the j-th row of even display units includes the second sub-pixel in the j-th row of pixel units, the third sub-pixel in the j-th row of pixel units, the first sub-pixel in the (j+1)-th row of pixel units, and the second sub-pixel in the (j+1)-th row of pixel units, i is a natural number between 1 and M, and j is a natural number between 1 and (M-1).

[0056] The display method of the display panel provided by the embodiment of the present disclosure divides the display panel with an original resolution of M*N into a resolution of 2N in the vertical direction, that is, the original one pixel unit is cut into two and controlled separately, and the horizontal direction is multiplexed by two frames, one frame constructs M resolution with the second sub-pixel as the pixel center of gravity, and the other frame constructs (M-1) resolution with the third sub-pixel and the first sub-pixel as the pixel center of gravity. The two frames are displayed alternately to construct a (2M-1) resolution display, thereby enhancing the image display resolution and achieving resolution improvement in the 2D display mode.

[0057] The display method can be integrated into the driver chip of the display panel as an algorithm IP (Intellectual property) module. By processing the data of the input image, the 2M*2N high-resolution image is split into 2 frames of M*2N images for alternating display, thereby achieving an improvement in resolution. On the other hand, since the two frames of display are fused into one frame, the actual display frequency is half of the display frequency of the display. Therefore, the higher the display frequency, the better. On a display panel with a low refresh rate, it will cause jitter of the two frames of display. The current display technology can generally reach a refresh rate of 120Hz. After using the display method of the embodiment of the present disclosure, the refresh rate can reach 60Hz, which can also achieve a better visual effect.

[0058] In some exemplary embodiments, each frame of the image to be displayed is split into odd-numbered lines of images and even-numbered lines of images by the video generation end, or split into odd-numbered lines of images and even-numbered lines of images by the video playback end.

[0059] like Figure 4 As shown, when each frame of the image to be displayed is split into odd-numbered row images and even-numbered row images by the video generation end, the system at the video generation end divides a frame of high-resolution (2M*2N) image into two frames of odd-numbered row images and even-numbered row images (usually a graphics processing unit (GPU) processes according to the requirements of extracting data from odd and even rows), and transmits them to the display panel. In this way, each frame of 2M*2N image can be divided into two frames of M*2N resolution images, and transmitted to the display panel through two frames F1 and F2, and this pattern is repeated. At this time, the display panel needs to pre-store a row of display data in the cache.

[0060] like Figure 5As shown, when each frame of the image to be displayed is split into odd-numbered row images and even-numbered row images by the video playback end, the system at the video generation end does not need to change the shape of the picture transmitted by the system, and directly splits the image transmitted from the system at the video generation end at the display panel end. At this time, the display panel needs to pre-store half of the frame data in the cache (when the image to be displayed is an 8K image, the display panel needs to cache 4K image data), which occupies more storage resources of the display panel driver chip.

[0061] like Figure 6 As shown, the video generation end generates an image with a resolution of 2M*2N, which is then split into odd-numbered row images and even-numbered row images by the video generation end or the video playback end, so that the odd-numbered display group displays the odd-numbered row images line by line, and the even-numbered display group displays the even-numbered row images.

[0062] The image segmentation method can be referred to Figure 7 As shown, the odd and even rows are split according to the row numbers, wherein the odd row image data constitutes the odd row image, and the even row image data constitutes the even row image, and the odd row image and the even row image are transmitted to the display panel one by one. Since the even row display group will lose one row of data when displaying the even row image, the last row of the original image does not need to be transmitted, that is, the even row image (F2 frame) transmits one less row of data than the odd row image (F1 frame).

[0063] In some exemplary embodiments, each pixel unit includes 2b first sub-pixels arranged along the first direction, 2b second sub-pixels arranged along the first direction, and 2b third sub-pixels arranged along the first direction, where b is a natural number greater than or equal to 1, and each pixel unit is divided into 2 sub-pixel units, each sub-pixel unit includes b first sub-pixels arranged along the first direction, b second sub-pixels arranged along the first direction, and b third sub-pixels arranged along the first direction. For example, Figure 3 As shown, b=2.

[0065] For 1≤X≤M, 1≤Y≤2N, the first sub-pixel in the sub-pixel unit in the Xth row and Yth column displays the grayscale value of the first image pixel unit in the Xth row and Yth column in the odd-numbered row image, the second sub-pixel in the sub-pixel unit in the Xth row and Yth column displays the grayscale value of the second image pixel unit in the Xth row and Yth column in the odd-numbered row image, and the third sub-pixel in the sub-pixel unit in the Xth row and Yth column displays the grayscale value of the third image pixel unit in the Xth row and Yth column in the odd-numbered row image.

[0066] In this embodiment, if it is an F1 frame image, according to Figure 8The image is displayed with a resolution of M*2N. The RGB of the "00" pixel in the input F1 frame image corresponds to the RGB pixels centered at the second sub-pixel "00" in the displayed image. Figure 8 As shown, each rectangular box of the input image on the left represents the input RGB pixel data; each bold black rectangular box in the display image on the right corresponds to an odd display unit, wherein an odd display unit in the i-th row includes b first sub-pixels in the i-th row pixel unit, b second sub-pixels in the i-th row pixel unit, and b third sub-pixels in the i-th row pixel unit, i is a natural number between 1 and M, and several sub-pixels of the same color in each odd display unit give the same display grayscale value. The assignment of input data to display pixels is in a one-to-one correspondence, refer to the following formula.

[0067] Display R(X, Y)(1-b) = input R(X, Y); Display G(X, Y)(1-b) = input G(X, Y); Display B(X, Y)(1-b) = input B(X, Y); where X = 1~M, Y = 1~2N.

[0068] In some exemplary embodiments, causing the even-numbered display group to display an even-numbered line image includes:

[0069] For 2≤c≤M, 1≤Y≤2N, the first sub-pixel in the sub-pixel unit in the c-th row and the Y-th column displays the grayscale value of the first image pixel unit in the c-1-th row and the Y-th column in the even-numbered row image;

[0070] For 1≤Y≤2N, the second sub-pixel in the 1st row and the Yth column sub-pixel unit displays A times the grayscale value of the second image pixel unit in the 1st row and the Yth column in the even-numbered row image, where A is a real number between 0 and 1;

[0071] For 2≤d≤(M-1), 1≤Y≤2N, the second sub-pixel in the d-th row and Y-th column sub-pixel unit displays the sum of A times the grayscale value of the second image pixel unit in the d-th row and Y-th column in the even-numbered row image and (1-A) times the grayscale value of the second image pixel unit in the (d-1)-th row and Y-th column in the even-numbered row image;

[0072] For 1≤Y≤2N, the second sub-pixel in the Mth row and Yth column sub-pixel unit displays (1-A) times the grayscale value of the second image pixel unit in the (M-1)th row and Yth column in the even-numbered row image;

[0073] For 1≤e≤(M-1), 1≤Y≤2N, the third sub-pixel in the sub-pixel unit of the e-th row and the Y-th column displays the grayscale value of the third image pixel unit of the e-th row and the Y-th column in the even-numbered row image.

Fig. 9 As shown, each rectangular box of the input image on the left represents the input RGB pixel data; each bold black rectangular box in the display image on the right corresponds to an even display unit, wherein an even display unit in the jth row includes b second sub-pixels in the jth row pixel unit, b third sub-pixels in the jth row pixel unit, b first sub-pixels in the (j+1)th row pixel unit, and b second sub-pixels in the (j+1)th row pixel unit, j is a natural number between 1 and (M-1), and two adjacent even display units located in the jth row and the j+1th row, respectively, need to share b second sub-pixels in the (j+1)th row pixel unit, and several sub-pixels of the same color in each even display unit are given the same display grayscale value. The assignment of input data to display pixels can refer to the following steps (assuming that the first sub-pixel is a red sub-pixel, the second sub-pixel is a green sub-pixel, and the third sub-pixel is a blue sub-pixel):

[0079] (1) The first row of red sub-pixels is specially processed and can be set to 0 or the same as the value in the F1 frame (in this case, a row of data in the F1 frame can be stored for use in the F2 frame).

[0080] Display R(1, Y)(1-b)=0; or, Display R(1, Y)(1-b)(F2)=Display R(1, Y)(1-b)(F1), 1≤Y≤2N.

[0081] The non-first row red sub-pixel data is processed according to the following formula:

[0082] Display R(c, Y)(1-b)=input R(c-1, Y), 2≤c≤M.

[0083] (2) Green sub-pixel processing: The displayed "10" G sub-pixel splits the input "10" G sub-pixel into two sub-pixels, G1 and G2. G1 is displayed for "10" G, and G2 is stored in the cache (linebuffer). After the "30" pixel is split, it is added to and assigned to "30" G. The G2 corresponding to "30" is also stored again, and after the "50" G is split, it is added and assigned, and so on. The splitting algorithm can directly divide the original G pixel value by 2. You can refer to the following formula:

[0084] First row G: Display G(1, Y)(1-b)=A*input G(1, Y);

[0085] Other rows G: Display G(d, Y)(1-b)=A*input G(d, Y)+(1-A)*input G(d-1, Y), 2≤d≤(M-1);

[0086] Last line G: Display G(M, Y)(1-b)=(1-A)*input G(M-1, Y);

[0087] A can be set to any value between 0 and 1, and for example, A=0.5.

[0088] (3) The non-tail blue sub-pixel data is processed according to the following formula:

[0089] Display B(e, Y)(1-b)=input B(e, Y), 1≤e≤(M-1).

[0090] The blue sub-pixels in the last row are specially processed and can be set to 0 or the same as the value in the F1 frame (storing a row of data in the F1 frame for use in the F2 frame).

[0091] Display B(M, Y)(1-b)=0; or Display B(M, Y)(1-b)(F2)=Display B(M, Y)(1-b)(F1).

[0092] In some exemplary embodiments, acquiring multiple frames of images to be displayed includes:

[0093] Receive the original image, the resolution of the original image is M*N;

[0094] Perform stretching processing on the original image to obtain a fourth intermediate processed image, wherein the resolution of the fourth intermediate processed image is 2M*2N;

[0095] The fourth intermediate processed image is split into odd-numbered line images and even-numbered line images to obtain an image to be displayed.

[0096] In this embodiment, Fig.10 and Fig.11As shown, the low-resolution image (resolution of M*N) input from the video generation end needs to be enlarged at the display panel driver chip end, which can usually be processed using interpolation algorithms such as bicubic interpolation to obtain a high-resolution image (resolution of 2M*2N). The obtained high-resolution image is then split into odd-row images and even-row images using the above display method, and displayed according to the above display method. At this time, the display panel needs to pre-store 1 / 4 of the frame data in the cache (when the image to be displayed is an 8K image, the display panel needs to cache 2K image data).

[0097] In some exemplary embodiments, the display method further includes:

[0098] Receive multiple frames of original images, the resolution of the original images is M*N;

[0099] Determine the moving speed of objects in multiple frames of original images;

[0100] When the movement speed of the object in the multiple frames of original images is greater than a preset first movement speed, the original images are horizontally copied to obtain a first intermediate processed image, the resolution of the first intermediate processed image is M*2N, and the grayscale value of the image pixel unit in the 2Z-1th column is the same as the grayscale value of the image pixel unit in the 2Zth column, 1≤Z≤N, so that the M*2N sub-pixel units display the grayscale value of the M*2N image pixel units in the first intermediate processed image;

[0101] When the movement speed of an object in multiple frames of original images is less than or equal to a preset first movement speed, the original images are stretched to obtain a second intermediate processed image, the resolution of the second intermediate processed image is 2M*2N, and the second intermediate processed image is divided into odd-numbered row images and even-numbered row images to obtain an image to be displayed, which is displayed according to the display method of the aforementioned embodiment.

[0102] In this embodiment, Fig.12 and Fig.13 As shown, for the image with a resolution of M*N transmitted by the system, the multiplexing (MUX) module or the driving chip in the display panel can be used to judge and select subsequent processing. When the object in the image transmitted by the system moves slowly and is similar to a static image, the display method described above is used to stretch it to obtain a second intermediate processed image with a resolution of 2M*2N. The second intermediate processed image is split into an odd-numbered row image and an even-numbered row image to obtain an image to be displayed, and is displayed according to the above display method; when the difference between each frame of the image transmitted by the system is large, only the vertical 2x replication method is used to maintain the original vertical resolution, and there is no need to increase the horizontal resolution. By means of this, a high refresh rate for dynamic images and a high resolution for static images can be achieved, which is more in line with the characteristics of the human eye.

[0103] The present disclosure also provides a display method for a display panel. Fig.14 As shown, the display panel includes M*N pixel units P, each pixel unit P includes a first sub-pixel P1, a second sub-pixel P2, and a third sub-pixel P3, and the first sub-pixel P1, the second sub-pixel P2, and the third sub-pixel P3 are arranged along a second direction D2. The display method includes:

[0104] Acquire multiple frames of images to be displayed, wherein one of two adjacent frames of images to be displayed is an odd-numbered line image, and the other is an even-numbered line image, the resolution of the odd-numbered line image is M*N, and the resolution of the even-numbered line image is M*N or (M-1)*N;

[0105] The odd display group displays an odd-numbered row image, and the even display group displays an even-numbered row image, the odd display group includes M*N odd display units, the even display group includes (M-1)*N even display units, the i-th row of odd display units includes the first sub-pixel P1 in the i-th row of pixel units, the second sub-pixel P2 in the i-th row of pixel units, and the third sub-pixel P3 in the i-th row of pixel units, the j-th row of even display units includes the second sub-pixel P2 in the j-th row of pixel units, the third sub-pixel P3 in the j-th row of pixel units, the first sub-pixel P1 in the (j+1)-th row of pixel units, and the second sub-pixel P2 in the (j+1)-th row of pixel units, i is a natural number between 1 and M, and j is a natural number between 1 and (M-1).

[0106] The display method of the display panel provided by the embodiment of the present disclosure converts the display panel whose original resolution is M*N into two frames in the horizontal direction, wherein one frame constructs M resolution with the second sub-pixel as the pixel centroid, and the other frame constructs (M-1) resolution with the third sub-pixel and the first sub-pixel as the pixel centroid, and the two frames are displayed alternately to construct a (2M-1) resolution display, thereby enhancing the image display resolution and achieving resolution improvement in the 2D display mode.

[0107] The display method can be integrated into the driver chip of the display panel as an algorithm IP (Intellectual property) module. By processing the data of the input image, the 2M*N high-resolution image is split into 2 frames of M*N images for alternating display, thereby achieving an improvement in resolution. On the other hand, since the two frames of display are fused into one frame, the actual display frequency is half of the display frequency of the display. Therefore, the higher the display frequency, the better. On a display panel with a low refresh rate, it will cause jitter of the two frames of display. The current display technology can generally reach a refresh rate of 120Hz. After using the display method of the embodiment of the present disclosure, the refresh rate can reach 60Hz, which can also achieve a better visual effect.

[0108] In some exemplary embodiments, each frame of the image to be displayed is split into odd-numbered lines of images and even-numbered lines of images by the video generation end, or split into odd-numbered lines of images and even-numbered lines of images by the video playback end.

[0109] When each frame of the image to be displayed is split into odd-numbered row images and even-numbered row images by the video generation end, the system at the video generation end divides a frame of high-resolution 2M*N images into two frames of odd-numbered row images and even-numbered row images (usually the GPU processes according to the requirements of extracting data from odd and even rows), and transmits them to the display panel. In this way, each frame of 2M*N images can be divided into two frames of M*N resolution images, and transmitted to the display panel through two frames F1 and F2, and this pattern is repeated. At this time, the display panel needs to pre-store a row of display data in the cache.

[0110] When each frame of the image to be displayed is split into odd-numbered row images and even-numbered row images by the video playback end, the system at the video generation end does not need to change the shape of the picture transmitted by the system, and directly splits the image transmitted from the system at the video generation end at the display panel end. At this time, the display panel needs to pre-store half of the frame data in the cache (when the image to be displayed is an 8K image, the display panel needs to cache 4K image data), which occupies more storage resources of the display panel driver chip.

[0111] In this embodiment, the video generation end generates an image with a resolution of 2M*N, which is then split into odd-row images and even-row images by the video generation end or the video playback end, so that the odd display group displays the odd-row images line by line, and the even display group displays the even-row images.

[0112] When splitting the image, the odd and even rows are split according to the row numbers, wherein the odd row image data constitutes the odd row image, and the even row image data constitutes the even row image. The odd row image and the even row image are transmitted to the display panel one by one. Since the even row display group will drop a row of data when displaying the even row image, the last row of the original image does not need to be transmitted, that is, the even row image (F2 frame) transmits 1 row less data than the odd row image (F1 frame).

[0113] In some exemplary embodiments, causing the odd display group to display an odd-numbered line image includes:

[0114] For 1≤x≤M, 1≤y≤N, the first sub-pixel in the pixel unit of the x-th row and y-th column displays the grayscale value of the first image pixel unit of the x-th row and y-th column in the image of the odd rows, the second sub-pixel in the pixel unit of the x-th row and y-th column displays the grayscale value of the second image pixel unit of the x-th row and y-th column in the image of the odd rows, and the third sub-pixel in the pixel unit of the x-th row and y-th column displays the grayscale value of the third image pixel unit of the x-th row and y-th column in the image of the odd rows.

[0115] In this embodiment, if it is an F1 frame image, according to Fig.15 The image is displayed with a resolution of M*N. The RGB of the pixel "00" in the input F1 frame image corresponds to the RGB pixel centered at the second sub-pixel "00" in the displayed image. Fig.15 As shown, each rectangular box of the input image on the left represents the input RGB pixel data; each bold black rectangular box in the display image on the right corresponds to an odd display unit, wherein an odd display unit in the i-th row includes a first sub-pixel in the i-th row pixel unit, a second sub-pixel in the i-th row pixel unit, and a third sub-pixel in the i-th row pixel unit, and i is a natural number between 1 and M.

[0120] For 2≤d≤(M-1), 1≤y≤N, the second subpixel in the pixel unit in the d-th row and the y-th column displays the sum of A times the grayscale value of the second image pixel unit in the d-th row and the y-th column in the even-numbered row image and (1-A) times the grayscale value of the second image pixel unit in the (d-1)-th row and the y-th column in the even-numbered row image;

[0121] For 1≤y≤N, the second sub-pixel in the pixel unit of the Mth row and the yth column displays (1-A) times the grayscale value of the second image pixel unit of the (M-1)th row and the yth column in the even-numbered row image;

[0122] For 1≤e≤(M-1), 1≤y≤N, the third sub-pixel in the pixel unit in the e-th row and the y-th column displays the grayscale value of the third image pixel unit in the e-th row and the y-th column in the even-numbered row image.

The assignment of input data to display pixels can refer to the following steps (assuming that the first sub-pixel is a red sub-pixel, the second sub-pixel is a green sub-pixel, and the third sub-pixel is a blue sub-pixel):

After the "30" pixel is split, it is added to it and assigned to "30" G; and the G2 corresponding to "30" is also stored again, and after the "50" G is split, it is added and assigned, and so on. Exemplarily, the splitting algorithm can directly divide the original G pixel value by 2. The following formula can be used as a reference:

[0132] First row G: Display G(1, y) = A* Input G(1, y);

[0133] Other rows G: Display G(d, y) = A*input G(d, y) + (1-A)*input G(d-1, y), 2≤d≤(M-1);
