Description
Technical Field
[0001] The present disclosure relates to the field of display technology, and in particular to a display panel, a display device, and a display driving method. Background Art
[0002] Modern consumer electronic devices are often equipped with liquid crystal display (LCD) or organic light-emitting diode (OLED) display panels as a human-machine interface. Each display panel includes a pixel array. Typically, the pixel array is based on electronic data generated from the original image. The image is divided into pixels of equal area, and the number of pixels is equal to the number of pixel elements on the display panel. With the increasing demand for display screens, especially mobile phone display screens, the installation of under-screen camera modules has become a current development trend of display panels.
[0003] For the display panel with an under-screen camera module, the display area corresponding to the under-screen camera module on the display panel can present a picture display when in the display state, and the entire display panel presents a full-screen display effect; when not in the display state, the display area corresponding to the under-screen camera module can be transparent to allow external ambient light to pass through for image capture by the camera module.

[0057] In order to make the technical problems, technical solutions and advantages to be solved by the present disclosure clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.
[0058] To address the problem that, for a display panel using an under-screen camera, pixels in the display area corresponding to the camera are reduced compared to the normal display area in order to meet the light transmittance requirements, which results in the display resolution of the display area corresponding to the camera being lower than that of the normal display area, seriously affecting the display effect, the present disclosure provides a display panel and a display driving method. By designing the pixel structure of the display area and formulating a corresponding pixel rendering technology (Sub Pixel Rendering, SPR), while ensuring that the display area corresponding to the camera achieves maximum transmittance, the display effect of this area is made closer to that of the normal display area, thereby reducing the regional difference between the normal display area and the display area corresponding to the camera.
[0059] like Figure 1 As shown, the display panel described in the embodiment of the present disclosure includes a first display area 11 and a second display area 12 that are adjacent to each other.
[0060] Among them, the second display area 12 is formed as a translucent display area. When the display panel is installed on an electronic device, a photosensitive element such as a camera can be installed inside the electronic device at a position corresponding to the second display area 12, which is used to capture images through the second display area 12, forming an under-screen camera display structure.
[0061] Optionally, the first display area 11 is arranged around the second display area 12, and the first display area 11 and the second display area 12 are combined to form the entire display area of the display panel. In one embodiment, the entire display area of the display panel can be a light-transmitting display area, or only the second display area 12 is a light-transmitting display area of the display panel, for enabling image acquisition by the under-screen camera. Optionally, the display panel is an OLED display panel.
[0062] like Figure 2 As shown, in the display panel described in the embodiment of the present disclosure, the first display area 11 includes a plurality of pixel repeating units 100 connected in sequence, and the second display area 12 includes a plurality of pixel repeating units 100 spaced apart from each other. The first display area 11 has a first pixel density, and the second display area 12 has a second pixel density, where the first pixel density is greater than the second pixel density. By reducing the pixel distribution density of the second display area 12, the transmittance of the second display area 12 is increased, meeting the image acquisition requirements of the under-screen camera.
[0063] It should be noted that in Figure 2In the figure, the shaded areas on the second display area 12 are actual sub-pixels, forming a plurality of pixel repeating units 100; the RGB sub-pixels indicated by the blank areas between the plurality of pixel repeating units 100 are not actual sub-pixels, and are indicated by the sub-pixel areas only for illustrating the positional relationship between the plurality of pixel repeating units 100.
[0064] Among them, such as Figure 2 As shown, combined with Figure 3 The first display area 11 and the second display area 12 each include a plurality of pixel repeating units 100. Each pixel repeating unit 100 includes two pixel groups 101 located in adjacent pixel rows. The distance between the two pixel groups 101 located in the same pixel repeating unit 101 is the shortest compared to the distance between the two pixel groups 101 located in different pixel repeating units 101.
[0065] Each pixel group 101 includes multiple sub-pixels of different colors, and in the two pixel groups 101 located in the same pixel repeating unit 100, the sub-pixels of different colors are arranged in a different order along the pixel row. The sub-pixels of the first color and the sub-pixels of the third color in the first pixel group are respectively adjacent to the sub-pixels of the second color in the second pixel group, and the sub-pixels of the first color and the sub-pixels of the second color in the second pixel group are adjacent to the sub-pixels of the third color in the first pixel group.
[0066] Using the display panel described in this embodiment, each pixel repetition unit 100 includes two pixel groups 101 located in adjacent rows. When performing display driving, the sub-pixels in each pixel repetition unit 100 can be shared to determine the corresponding driving pixel unit, and the SPR driving algorithm is used to form a virtual pixel unit, thereby achieving the effect of improving the resolution of the display area corresponding to the camera, ensuring that the display area corresponding to the camera achieves the maximum transmittance, and achieving the effect of improving the resolution of the display area, so that the display effect of the second display area is closer to the display effect of the normal display area (the first display area).
[0067] In addition, the display panel described in the embodiment of the present disclosure utilizes two pixel groups, in which the sub-pixels of the first color and the sub-pixels of the third color in the first pixel group are respectively adjacent to the sub-pixels of the second color in the second pixel group, and the sub-pixels of the first color and the sub-pixels of the second color in the second pixel group are adjacent to the sub-pixels of the third color in the first pixel group, so that in the two pixel groups, the sub-pixels of one color in the first pixel group are adjacent to the sub-pixels of a different color in the second pixel group. In this way, when the SPR driving algorithm is used to form a virtual pixel unit, the sub-pixels of different pixel groups in each pixel repetition unit 100 can be shared, thereby achieving the effect of improving the resolution of the corresponding display area of the camera.
[0068] In the embodiment of the present disclosure, optionally, combined with Figure 2 and Figure 3 As shown, the pixel repeating unit 100 includes two pixel groups 101. In the first pixel group 1011, a blue B sub-pixel, a green G sub-pixel, and a red R sub-pixel are arranged in sequence; in the second pixel group 1012, a red R sub-pixel, a blue B sub-pixel, and a green G pixel are arranged in sequence. The blue B sub-pixel and the green G sub-pixel in the first pixel group 1011 are adjacent to the red R sub-pixel in the second pixel group 1012, and the green G sub-pixel in the first pixel group 1011 and the red R sub-pixel in the first pixel group 1011 are adjacent to the blue B sub-pixel in the second pixel group 1012. Similarly, the red R sub-pixel and the blue sub-pixel in the second pixel group 1012 are respectively adjacent to the green G sub-pixel in the first pixel group 1011; and the blue B sub-pixel and the green G sub-pixel in the second pixel group 1012 are respectively adjacent to the red R sub-pixel in the first pixel group 1011.
[0069] In the embodiment of the present disclosure, Figure 3 As shown, the pixel repeating unit 100 includes two pixel groups 101, and the second pixel group 1012 is offset by half of a sub-pixel width L compared to the first pixel group 1011 along the row extension direction a (first direction); that is, the second pixel group 1012 is offset by a width of L / 2 compared to the first pixel group 1011 along the row extension direction a.
[0070] It should be noted that in the disclosed embodiments, the row extension direction a can be defined as the horizontal direction from left to right when the display panel displays an image, i.e., the direction pointing toward one edge of the pixel row of the display panel; the opposite row extension direction b is the direction opposite to the row extension direction a, i.e., the second direction. The column extension direction c can be defined as the vertical direction from top to bottom when the display panel displays an image. Similarly, the opposite column extension direction d is the direction opposite to the column extension direction c.
[0071] Optionally, in the display panel described in the embodiment of the present disclosure, in the two pixel groups 101, the width of each sub-pixel on the pixel row is equal, and the sub-pixels of the first color in the second pixel group 1012 are offset by 1.5 sub-pixel widths L along the extension direction a of the row compared to the sub-pixels of the first color in the first pixel group 1011.
[0072] Furthermore, the sub-pixels of the second color in the second pixel group 1012 are offset by 1.5 sub-pixel widths along the direction b opposite to the extending direction of the row, compared to the sub-pixels of the second color in the first pixel group 1011 .
[0073] Specifically, if Figure 3As shown, taking two pixel groups 101 including blue, red and green sub-pixels respectively, with the first color being blue, the second color being red, and the third color being green as an example, the sub-pixels of the first color (i.e., blue) in the second pixel group 1012 are offset by 1.5 sub-pixel widths L along the row extension direction a compared to the sub-pixels of the first color (i.e., blue) in the first pixel group 1011.
[0074] Furthermore, in the two pixel groups 101, the sub-pixels of the second color (i.e., red) in the second pixel group 1012 are offset by 1.5 sub-pixel widths L in the opposite direction b of the row extension direction compared to the sub-pixels of the second color (i.e., red) in the first pixel group 1011.
[0075] On this basis, the sub-pixels of the third color (ie green) in the third pixel group 1012 are offset by 1.5 sub-pixel widths L along the row extension direction a compared to the sub-pixels of the third color (ie green) in the first pixel group 1011 .
[0076] In the embodiment of the present disclosure, Figure 2 and Figure 3 As shown, each pixel group 101 includes a sub-pixel of the first color, a sub-pixel of the second color, and two sub-pixels of the third color arranged along the extension direction of the column (arranged along the pixel column), wherein the total luminous area of the two sub-pixels of the third color is equal to the luminous area of the sub-pixel of the first color, and the luminous area of the sub-pixel of the first color is equal to the luminous area of the sub-pixel of the second color.
[0077] Alternatively, as Figure 2 and Figure 3 As shown, in the first pixel group 1011 of the two pixel groups 101, along the extension direction a of the row, the sub-pixels of the first color, the two sub-pixels of the third color arranged along the direction of the column, and the sub-pixels of the second color are arranged in sequence; in the second pixel group 1012 of the two pixel groups 101, along the extension direction a of the row, the sub-pixels of the second color, the sub-pixels of the first color, and the two sub-pixels of the third color arranged along the direction of the column are arranged in sequence.
[0078] In the embodiment of the present disclosure, optionally, the first color is blue, the second color is red, and the third color is green.
[0079] That is, specifically, Figure 2 and Figure 3As shown, in a pixel repetition unit 100, along the extension direction a of the row, in the first pixel group 1011 of the adjacent row, the blue sub-pixel, two green sub-pixels arranged along the column direction, and the red sub-pixel are arranged in sequence; in the second pixel group 1012, along the extension direction a of the row, the red sub-pixel, the blue sub-pixel, and two green sub-pixels arranged along the column direction are arranged in sequence.
[0080] It should be noted that, in the first pixel group 1011 and the second pixel group 1012 of adjacent rows, the arrangement order of sub-pixels of different colors is not limited to the above-listed forms. As long as the arrangement order of sub-pixels of different colors in the two pixel groups 101 is different, and the sub-pixels of the first color in the second pixel group 1012 are offset by 1.5 sub-pixel widths along the extension direction of the row compared to the sub-pixels of the first color in the first pixel group 1011, and the sub-pixels of the second color in the second pixel group 1012 are offset by 1.5 sub-pixel widths along the opposite direction of the extension direction of the row compared to the sub-pixels of the second color in the first pixel group 1011, in the two pixel groups, the sub-pixels of one color in the first pixel group are adjacent to the sub-pixels of different colors in the second pixel group, which belongs to the setting structure of the pixel repetition unit 100 in the display panel described in the present disclosure.
[0081] Furthermore, in the display panel of the embodiment of the present disclosure, in the second display area 12 , along the row extension direction a and along the column extension direction c, each pixel repeating unit 100 is separated from the adjacent pixel repeating unit 100 by an area of at least one pixel repeating unit 100 .
[0082] Specifically, if Figure 2 As shown, along the row extension direction a, adjacent first pixel repeating units 110 and second pixel repeating units 120 are separated by an area of one pixel repeating unit 100, that is, by a width of one pixel repeating unit along the row extension direction a; along the column extension direction b, adjacent first pixel repeating units 110 and third pixel repeating units 130 are separated by an area of one pixel repeating unit 100, that is, by a width of one pixel repeating unit along the column extension direction b, specifically, the width of two pixel rows.
[0083] The display panel described in the embodiment of the present disclosure adopts the above-described structure and includes multiple pixel repeating units 100. In a first display area 11, the multiple pixel repeating units 100 are sequentially connected and arranged along the row and column extension directions. In a second display area 12, the multiple pixel repeating units 100 are spaced apart from each other along the row and column extension directions. Furthermore, in each of the first and second display areas 11 and 12, each pixel repeating unit 100 includes two pixel groups 101, which are distributed in two adjacent pixel rows.
[0084] Optionally, in a pixel repetition unit 100, when the first color is blue, the second color is red, and the third color is green, the above-mentioned arrangement of sub-pixels in the first pixel group 1011 and the second pixel group 1012 is adopted, and the distance between the center of the red sub-pixel in the first pixel group 1011 and the center of the red sub-pixel in the second pixel group 1012 along the extension direction of the row is between 28um and 32um, optionally 30um; the distance along the extension direction of the column is between 30um and 36um, optionally 34um; the distance between the center of the blue sub-pixel in the first pixel group 1011 and the center of the blue sub-pixel in the second pixel group 1012 along the extension direction of the row is between 28um and 32um, optionally 30um; the distance along the extension direction of the column is between 40um and 45um, optionally 42um.
[0085] Optionally, in the plurality of pixel repeating units 100, each pixel group 101 includes four sub-pixels, namely red R, green G, green G, and blue B. The light-emitting area of the red sub-pixel is equal to the light-emitting area of the blue sub-pixel, the two green sub-pixels are arranged along the extension direction of the column, and the total light-emitting area of the two green sub-pixels is equal to the light-emitting area of the red sub-pixel and the light-emitting area of the blue sub-pixel.
[0086] By utilizing the arrangement of sub-pixels in the aforementioned pixel repeating unit 100 and employing an SPR driving algorithm, a virtual pixel unit is formed, wherein the G sub-pixel in each virtual pixel unit corresponds to the g signal in the red, green, and blue pixels, and the R and B sub-pixels correspond to the r and g signals in the adjacent red, green, and blue pixels according to an algorithm for sharing adjacent virtual pixels in the same row (i.e., a sub-pixel sharing algorithm).
[0087] Optionally, during display driving, in a pixel group 101, two G sub-pixels are arranged along the extension direction of the column, wherein the upper G sub-pixel is assigned to the previous row addressing, and the lower G sub-pixel is assigned to the current row pixel addressing.
[0088] Specifically, when performing display driving and receiving a row scan signal on a target row, in response to the row scan signal, the first pixel group 1011 and the second pixel group 1012 in each pixel repeating unit 100 are used to borrow sub-pixels, and multiple driving pixel units along the target row are sequentially illuminated, where each driving pixel unit includes a first portion of sub-pixels in the first pixel group 1011 in one of the pixel repeating units 100 and a second portion of sub-pixels in the second pixel group 1012 in the same pixel repeating unit 100.
[0089] The first pixel group 1011 or the second pixel group 1012 is located in the target row.
[0090] Optionally, the first portion of sub-pixels and the second portion of sub-pixels in each driven pixel unit include sub-pixels of different colors respectively.
[0091] It should be noted that, in the first pixel group 1011 and the second pixel group 1012 , multiple sub-pixels can be connected to driving signal lines of different rows respectively, that is, multiple sub-pixels in the same pixel group can belong to different pixel addressing rows.
[0092] Specifically, if Figures 2 to 5 As shown, when a target row receives a row scan signal, data signals are sequentially input to a plurality of driving pixel units 200 arranged along the extension direction a of the target row.
[0093] Optionally, when the target row is an odd-numbered row, in every two adjacent driven pixel units 200, the first driven pixel unit 201 includes a sub-pixel of the first color and a sub-pixel of the third color in the first pixel group 1011 of the pixel repeating unit 100, and a sub-pixel of the second color in the second pixel group 1012; the second driven pixel unit 202 includes a sub-pixel of the third color and a sub-pixel of the second color in the first pixel group 1011 of the pixel repeating unit 100, and a sub-pixel of the first color in the second pixel group 1012;

[0121] g i-1,j is the grayscale value of the G sub-pixel located in the i-1th row and jth column in the multiple pixel repeating units;
[0122] γ is the preset grayscale function.
[0123] Taking the first pixel group 1011 and the second pixel group 1012 as an example, in which the first color is blue, the second color is red, and the third color is green, when a data signal is input to the second pixel driving unit 202, the second pixel driving unit 201 includes the blue sub-pixels and green sub-pixels of the target row (even rows, that is, the row where the second pixel group 1012 is located), and also includes the red sub-pixels of the first pixel group 1011 (odd rows).
[0124] Specifically, when the target row is an even row and is row i, the virtual pixel unit formed by using the first driving pixel unit 201 can be expressed as (that is, when the target row i is an even row, the second virtual pixel unit formed by using the second driving pixel unit 202 can be expressed as):
[0125]
[0126] Among them, G i,j 、R i,j 、B i,j are the grayscale values of the G sub-pixel, B sub-pixel, and R sub-pixel of the virtual pixel unit in the i-th row and j-th column respectively;

[0131] γ is a preset grayscale function. Optionally, γ can be determined based on a pre-test.
[0132] Based on the above, and combined with Figure 4 and Figure 5 In the display driving method of the embodiment of the present disclosure, in a first pixel group of the two pixel groups, a sub-pixel of a first color, two sub-pixels of a third color arranged along a pixel column direction, and a sub-pixel of a second color are sequentially arranged along a pixel row direction; and in a second pixel group of the two pixel groups, a sub-pixel of the second color, a sub-pixel of the first color, and two sub-pixels of the third color arranged along a pixel column direction are sequentially arranged along a pixel row direction, when the target row i is an odd row, the sub-pixels in the driven pixel unit are illuminated, and in two adjacent virtual pixel units in the formed i-th row, when the first virtual pixel unit is in the i-th row and the j-th column, the illuminated sub-pixels include:
[0133] a sub-pixel of the second color (R color) located at the i-th row and the j+1-th column;
[0134] The sub-pixel of the first color (color B) located at the i-th row and the j-th column;
[0135] a sub-pixel of the third color (G color) located at the j-1th row and j-1th column;
[0136] a sub-pixel of the third color located in the i-th row and the j-th column;
[0137] When the second virtual pixel unit is in the i-th row and the j-th column, the sub-pixels that are lit include:
[0138] a sub-pixel of the second color located in the i-th row and the j+1-th column;
[0139] a sub-pixel of the first color located in the i+1th row and j+1th column;
[0140] a sub-pixel of the third color located at the i-1th row and j-1th column;
[0141] The sub-pixel of the third color located in the i-th row and the j-th column.
[0142] With the above-mentioned display driving method, when a row scan signal is input to an odd row, the first pixel drive unit 201 and the second pixel drive unit 202, which are adjacent to each other for data signal input, share adjacent green sub-pixels; when a row scan signal is input to an even row, the first pixel drive unit 201 and the second pixel drive unit 202, which are adjacent to each other for data signal input, share adjacent blue sub-pixels. Therefore, compared with a normal physical pixel, a virtual intermediate pixel is added, and the original two pixel groups become four pixel groups in visual perception, thereby doubling the resolution compared with a normal display panel, thereby increasing the resolution of the second display area, i.e., corresponding to the camera area, and reducing the difference in display effect compared with the first display area.
[0143] By adopting this implementation structure, in order to increase the aperture ratio of the second display area, the number of physical pixels in the second display area can be reduced to one-fourth of the number of pixels set in conventional technology based on the original number.
[0144] To increase the aperture ratio of the second display area, the distribution density of physical pixels can be reduced to one-fourth of the pixel distribution density of the first display area. For example, if the pixel unit density of a conventional OLED display panel is 720p (the virtual reality resolution calculated using the SPR driving algorithm is 1080p), that is, the setting density of the virtual pixel unit formed is 720p, the physical pixel of the display area corresponding to the camera is 720 / 4=180p. The use of the SPR driving algorithm increases the resolution by 2 times, so the virtual resolution observed by the display area corresponding to the camera can be 360p.
[0145] Therefore, by using the display panel provided in the embodiment of the present disclosure, while ensuring that the display area corresponding to the camera reaches the maximum transmittance, the display effect of this area can be made closer to the display effect of the normal display area, so as to reduce the regional difference between the normal display area and the display area corresponding to the camera.
