Description

Technical Field

[0001] The present disclosure relates to the field of display technologies, and particularly to a display panel, a display device, and a display driving method. Background Art

[0002] Modern consumer electronic devices are mostly equipped with a liquid crystal display (LCD) panel or an organic light-emitting diode (OLED) display panel as a human-machine interface. Each display panel includes an array of pixel elements. Usually, the array of pixel elements is based on electronic data generated from an original image. The image is divided into pixels of equal areas, and the number of pixels is equal to the number of pixel elements on the display panel. With the gradually increasing application requirements of display screens, especially mobile phone display screens, setting an under-screen camera module has become the current development trend of display panels.

[0003] For a display panel with an under-screen camera module, on the display panel, the display area corresponding to the under-screen camera module can present a picture display in the display state, and the entire display panel shows a full-screen display effect; when not in the display state, the display area corresponding to the under-screen camera module can be transparent so that external ambient light can pass through for image acquisition by the camera module.

[0004] Currently, in order to make the display area corresponding to the under-screen camera module on the display panel meet the display effects of the above two states, pixel deletion is usually performed on this display area. However, with this setting structure, the pixel unit density of the display area is less than that of the normal display area, which will cause the display resolution of this display area to be less than that of the normal display area, thus seriously affecting the display effect. Summary of the Invention

[0068] To make the technical problems, technical solutions, and advantages to be solved by the present disclosure clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

[0069] To solve the problem that for a display panel with an under-screen camera, in order to meet the light transmission requirements, the pixel deletion is performed in the display area corresponding to the camera compared to the normal display area, which will cause the display resolution of the display area corresponding to the camera to be less than that of the normal display area, seriously affecting the display effect. The embodiments of the present disclosure provide 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 the maximum transmittance of the display area corresponding to the camera, the display effect of this area is closer to that of the normal display area.

[0070] As Figure 1 shown, the display panel according to an embodiment of the present disclosure includes adjacent first display area 11 and second display area 12.

[0071] Among them, the second display area 12 is formed as a light-transmitting display area. When the display panel is installed on an electronic device, inside the electronic device, at the position corresponding to the second display area 12, a photosensitive element such as a camera can be installed to collect images through the second display area 12, forming an under-screen camera display structure.

[0072] 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 implementation manner, the entire display area of the display panel can be a light-transmitting display area, or only the second display area 12 is the light-transmitting display area of the display panel for realizing image acquisition of the under-screen camera. Optionally, the display panel is an OLED display panel.

[0073] As Figure 2 and Figure 3 shown, for the display panel according to an embodiment of the present disclosure, the first display area 11 has a first pixel density, the second display area 12 has a second pixel density, and the first pixel density is greater than the second pixel density;

[0074] Among them, the first display area 11 and the second display area 12 respectively include a plurality of pixel repeating units 110. Each pixel repeating unit 110 respectively includes a first sub-pixel 111 of a first color, a second sub-pixel 112 of a second color, a third sub-pixel 113 of a third color, and a fourth sub-pixel 114 of the first color arranged in sequence along the first direction a. Among them, the light-emitting areas of the first sub-pixel 111 of the first color and the fourth sub-pixel 114 of the first color are both smaller than the light-emitting areas of the second sub-pixel 112 of the second color and the third sub-pixel 113 of the third color.

[0075] In the second display area 12, among three adjacent pixel rows, a virtual pixel space 3 is formed on the second pixel row between the first pixel repeating unit 1 of the first pixel row and the second pixel repeating unit 2 of the third pixel row. The area of the virtual pixel space 3 is at least greater than or equal to the area occupied by one pixel repeating unit 110. Among them, the length extension direction of the pixel row is parallel to the first direction a.

[0076] For the display panel according to the embodiment of the present disclosure, optionally, the sub-pixels of the plurality of pixel repeating units 110 in the first display area 11 are connected and arranged in sequence, and there is an interval space between the plurality of pixel repeating units 110 in the second display area 12, forming a structure in which the first pixel density of the first display area 11 is greater than the second pixel density of the second display area 12. It should be noted that in Figure 2 In the second display area 12, the shaded filled part is the actual sub-pixels, forming a plurality of pixel repeating units 110; the RGB sub-pixels marked in the blank part between the plurality of pixel repeating units 110 are not actual sub-pixels, which are marked with sub-pixel areas and are only used to illustrate the positional relationship between the plurality of pixel repeating units 110.

[0077] For the display panel according to the embodiment of the present disclosure, on the basis of setting the pixel repeating unit 110 according to the above-mentioned implementation structure, in three adjacent pixel rows in the second display area 12, the first pixel repeating unit 1 and the second pixel repeating unit 2 located on the spaced pixel rows, a virtual pixel space is formed on the pixel row between the two pixel repeating units 110, that is, there is no actually arranged pixel repeating unit. When performing image display driving, through the virtual pixel space, the SPR driving algorithm can be used to form a virtual pixel unit in the virtual pixel space, ensuring the maximum transmittance of the camera corresponding display area while achieving the effect of improving the resolution of the display area, making the display effect of the second display area closer to the display effect of the normal display area (the first display area).

[0078] In the embodiment of the present disclosure, optionally, as Figure 2 and Figure 4As shown, in the first display area 11, among three adjacent pixel repeating units 110, the first sub-pixel 111 of the first color in the second pixel repeating unit 1102 and the fourth sub-pixel 114 of the first color in the first pixel repeating unit 1101 are arranged along the second direction b, and the fourth sub-pixel 114 of the first color in the second pixel repeating unit 1102 and the first sub-pixel 111 of the first color in the third pixel repeating unit 1103 are arranged along the second direction b; the second direction b is perpendicular to the first direction a, and the first pixel repeating unit 1101, the second pixel repeating unit 1102, and the third pixel repeating unit 1103 are arranged in sequence along the first direction a.

[0079] Based on this implementation structure, in each pixel repeating unit 110, the widths of the first sub-pixel 111 and the fourth sub-pixel 114 in the second direction b are respectively one-half of the widths of the second sub-pixel 112 and the third sub-pixel 113 in the second direction b. Additionally, optionally, in each pixel repeating unit 110, the widths of the first sub-pixel 111, the second sub-pixel 112, the third sub-pixel 113, and the fourth sub-pixel 114 in the first direction a are all equal.

[0080] Based on this implementation manner, in the first display area 11, among two adjacent pixel repeating units 110, after the two first-color sub-pixels of the two adjacent pixel repeating units 110 are combined and arranged along the second direction b, the total width in the second direction is equal to the widths of the second-color sub-pixel and the third-color sub-pixel in the second direction, and the total area of the two first-color sub-pixels of the two adjacent pixel repeating units 110 after combination is equal to the area of one second-color sub-pixel, and is also equal to the area of one third-color sub-pixel.

[0081] In the embodiments of the present disclosure, optionally, the first color is green, the second color is red, and the third color is blue. It should be noted that for the display panel described in the embodiments of the present disclosure, when the first display area 11 and the second display area 12 are arranged according to the above manner, the first color, the second color, and the third color are not limited to only the above-listed colors respectively.

[0082] With the display panel described in this embodiment, in the first display area 11, it is formed into a structure where multiple Rs, Gs, and Bs are arranged in sequence. However, the G sub-pixel includes two pixel parts arranged along the second direction (i.e., the pixel column direction). Compared with the prior art, the two pixel parts of this G sub-pixel belong to different pixel repeating units respectively, and the two pixel parts can be respectively connected to different driving lines and driven to emit light respectively. In each pixel repeating unit 110 of the second display area 12, one sub-pixel of the first color is respectively arranged on one side of the second sub-pixel 112 of the second color and the third sub-pixel 113 of the third color, that is, the first sub-pixel 111 and the fourth sub-pixel 114. In this way, each pixel repeating unit 110 in the second display area 12 includes one second-color sub-pixel, one third-color sub-pixel, and two first-color sub-pixels.

[0083] The display panel described in the embodiment of the present disclosure, optionally, as Figure 2 and Figure 3 shown, in the second display area 12, in the same pixel row, two adjacent pixel repeating units 110 are arranged at intervals; that is, an interval space is formed between two adjacent pixel repeating units 110, and no pixel repeating unit is provided.

[0084] In addition, the multiple pixel repeating units 110 on two pixel rows separated by one row are arranged staggeredly. Specifically, as Figure 2 and Figure 3 shown, in three adjacent pixel rows, the positive projection of the first pixel repeating unit 1 in the first pixel row on the third pixel row separated by one row is at least partially located between the second pixel repeating unit 2 and the third pixel repeating unit 4 in the third pixel row. Optionally, the positive projection includes a part located between the second pixel repeating unit 2 and the third pixel repeating unit 4, and also includes parts that overlap with the second pixel repeating unit 2 and the third pixel repeating unit 4 respectively.

[0085] Referring to Figure 2 and Figure 3 shown, in the second display area 12, the interval space formed between two adjacent pixel repeating units 110 is an integer multiple of the width L of the sub-pixels of the pixel repeating unit 110 along the first direction a. Wherein, L is a non-zero natural number.

[0086] Specifically, along the first direction a, the widths of the first sub-pixel 111, the second sub-pixel 112, the third sub-pixel 113, and the fourth sub-pixel 114 are all L; wherein, in the second display area 12, on each pixel row, the width of the interval between two adjacent pixel repeating units 110 in the first direction a is an integer multiple of L.

[0087] Optionally, in the embodiments of the present disclosure, in the second display area 12, on each pixel row, the width of the interval between two adjacent pixel repeating units 110 in the first direction a is at least twice that of L.

[0088] Optionally, in the embodiments of the present disclosure, on the second pixel row, the width of the interval between two adjacent pixel repeating units 110 in the first direction a is an integer multiple of 3L.

[0089] With this implementation structure, a virtual pixel space 3 is formed on the second pixel row between the first pixel repeating unit 1 of the first pixel row and the second pixel repeating unit 2 of the third pixel row, and it is ensured that the area of the virtual pixel space 3 is at least greater than or equal to the area occupied by one pixel repeating unit 110.

[0090] Furthermore, in the embodiments of the present disclosure, as Figure 2 and Figure 3 shown, the orthographic projection of the first pixel repeating unit 1 on the third pixel row at least partially overlaps with the second pixel repeating unit 2, and the orthographic projection of the fourth pixel repeating unit 5 adjacent to the first pixel repeating unit 1 in the first direction a on the third pixel row also overlaps with the second pixel repeating unit 2. Specifically, when the first pixel repeating unit 1 is orthographically projected on the third pixel row, the orthographic projection of the fourth sub-pixel of the first color overlaps with the first sub-pixel of the first color of the second pixel unit 2. Optionally, on the first pixel row, when the fourth pixel repeating unit 5 adjacent to the first pixel repeating unit 1 in the first direction a is orthographically projected on the third pixel row, the orthographic projection of the first sub-pixel of the first color overlaps with the fourth sub-pixel of the first color of the second pixel repeating unit 2.

[0091] As Figure 3 shown, in the display panel described in the embodiments of the present disclosure, in the first display area 11 and the second display area 12, in each pixel repeating unit 110, the widths of the first sub-pixel 111 and the fourth sub-pixel 114 in the second direction b are respectively half of the widths of the second sub-pixel 112 and the third sub-pixel 113 in the second direction b.

[0092] In addition, optionally, as Figure 2 shown and combined with Figure 3 , on the second display area 12, compared with the first edge 121 where the second display area 12 is connected to the first display area 11, the first sub-pixel 111 and the fourth sub-pixel 114 of each pixel repeating unit 110 are both arranged on the side close to the first edge 121;

[0093] Among them, the second display area 12 further includes a second edge 122 connected to the first display area 11. The second edge 122 is opposite to the first edge 121, and the direction from the first edge 121 to the second edge 122 is parallel to the second direction b.

[0094] That is, specifically, in the second display area 12, for each pixel repeating unit 110, the first sub-pixel 111 and the fourth sub-pixel 114 are disposed on the pixel portion close to the first edge 121.

[0095] In addition, optionally, in the embodiments of the present disclosure, as Figure 2 shown, on the first display area 11 and the second display area 12, the sub-pixels of two adjacent pixel rows are arranged in a staggered manner.

[0096] Specifically, as Figure 2 shown, in the first display area 11, the sub-pixels of each pixel row and the sub-pixels of the adjacent row are respectively arranged in a staggered manner. That is, in each pixel row, the orthographic projection of any sub-pixel in the adjacent row overlaps with at least two adjacent sub-pixels in the adjacent row. Specifically, among two adjacent pixel rows, the first sub-pixel of the first color in the fourth pixel repeating unit 1104 of the first pixel row is offset by 1.5 sub-pixel widths along the first direction compared with the first sub-pixel of the first color in the fifth pixel repeating unit 1105 adjacent to the fourth pixel repeating unit 1104 in the second pixel row.

[0097] In the display panel according to the embodiments of the present disclosure, among the multiple pixel repeating units 110, the first sub-pixel 111 and the fourth sub-pixel 114 in the same pixel row are respectively connected to the first driving line, and the second sub-pixel 112 and the third sub-pixel 113 in the same pixel row are respectively connected to the second driving line. The first driving line and the second driving line are adjacent driving lines. Optionally, as Figure 4 shown, two first-color sub-pixels arranged along the second direction belong to the same pixel column but different pixel repeating units. In the embodiments of the present disclosure, they are respectively connected to different driving lines. For example, for two first-color sub-pixels arranged vertically, the upper sub-pixel is connected to the first driving line, and the lower sub-pixel is connected to the second driving line. Optionally, the first driving line belongs to the scanning signal input line of the upper row of the second driving line.

[0098] Optionally, when the first color is green, the second color is red, and the third color is blue, the G sub-pixels on both sides of the R sub-pixel and the B sub-pixel belong to the control sub-pixels of the upper row of lines, and the R sub-pixel and the B sub-pixel of this row belong to the control sub-pixels of this row of lines.

[0099] For the display panel adopting the implementation structure as Figure 2As shown, in the first display area 11, multiple pixel repeating units 110 are connected in sequence. When driving the display, the SPR algorithm is adopted. For two G sub-pixels arranged in sequence in the second direction, they can share the R sub-pixel and the B sub-pixel with the adjacent pixel repeating unit 110. Specifically, when driving the display, the addressing part for addressing the virtual pixel unit can be considered to include two addressing pixels, RG and BG.

[0100] Optionally, when driving the display, the two adjacent Gs addressed in the previous row are on both sides of the sub-pixels distributed horizontally and vertically, and the R and B addressed in this row are in the middle of the pixel. The G sub-pixel in this row is not lit. That is, the two G sub-pixels are controlled by the previous row on the driving row, the R sub-pixel and the B sub-pixel in this row are in the middle of the pixel, and the G sub-pixel controlled by this row is not lit.

[0101] In the first display area 11 and the second display area 12, each pixel repeating unit 110 is formed into Figure 4 the structure shown, and in every three adjacent pixel rows, the first pixel repeating unit 1 in the first pixel row and the second pixel repeating unit 2 in the third pixel row form a group of adjacent pixels, and no pixel structure is set between the first pixel repeating unit 1 and the second pixel repeating unit 2 within a group of adjacent pixels, forming a virtual pixel space for forming a virtual pixel unit through the SPR driving algorithm.

[0102] In the embodiment of the present disclosure, optionally, within a group of adjacent pixel repeating units, between the first pixel repeating unit 1 and the second pixel repeating unit 2, the center distance between two sub-pixels of the second color (the R sub-pixel in the embodiment of the present disclosure) is: X: 30um, Y: 76um; the center distance between two sub-pixels of the third color (the B sub-pixel in the embodiment of the present disclosure) is: X: 30um, Y: 83um.

[0103] It should be noted that the distance between sub-pixels is not limited to the above settings, and can be specifically determined according to the overall size of the display panel, the manufacturing process conditions, the light emission requirements, etc.

[0104] In the display panel according to the embodiment of the present disclosure, optionally, in the second display area 12, for the virtual pixel unit formed by multiple pixel repeating units 110, one virtual pixel unit shares the R and B sub-pixels with the adjacent virtual pixel unit on one side, as Figure 5 shown, the virtual pixel unit 6 and the virtual pixel unit 7, two adjacent virtual pixel units share the R and B sub-pixels.

[0105] In addition, when displaying an image, the G sub-pixel in each virtual pixel unit correspondingly represents the g signal of the actual pixel unit, and the R sub-pixel and the B sub-pixel respectively represent the r signal and the b signal of two adjacent actual pixel units.

[0106] Specifically, according to the line scanning signal on the target driving line when the display image is input, data signals are input to at least two adjacent pixel lines corresponding to the target driving line to form virtual pixel units. For example, refer to Figure 6 As shown, through the first pixel repeating unit 1 and the second pixel repeating unit 2, a virtual display pixel 100 can be formed. Combining Figure 2 、 Figure 3 As shown, and referring to Figure 6 , taking the image display of the second display area 12 as an example. Of course, the rules for image display in the first display area 11 and the second display area 12 are the same. When performing pixel addressing, in each pixel repeating unit 110, if the first sub-pixel of the first color is a G sub-pixel, it is assigned to the addressing of the virtual display pixel in the previous row. If the fourth sub-pixel of the first color is a G sub-pixel, it is assigned to the addressing of the adjacent virtual display pixel of the virtual display pixel in the previous row. Wherein, in this setting method, when inputting image data to the second display area 12, the virtual pixel space forms a virtual display pixel 100. The determination method of the SPR driving algorithm adopted during pixel addressing is, that is, the relationship between the formed virtual display pixel and the sub-pixels of the pixel repeating unit is expressed as:

[0107] G i,j = g i,j ; G i+1,j = g i+1,j ;

[0108]

[0109] G i+2,j = g i+2,j ; G i+2,j+2 = g i+2,j+2 ;

[0130] where γ is a preset gray function, and the gray function can be determined in advance according to experimental measurements.

[0131] Based on the above, in at least two adjacent pixel rows, some sub-pixels in the pixel repeating units on one pixel row and some sub-pixels in the pixel repeating units on the adjacent pixel row are lit in response to the row scanning signal to form virtual display pixels, including:

[0132] forming the sub-pixel of the first color of the virtual display pixel in the first row (the i-th row) through the first sub-pixel of the first color in a pixel repeating unit on the first pixel row (the i-th row);

[0136] forming the sub-pixel of the first color of the virtual display pixel in the third row (the (i + 2)-th row) through the first sub-pixel of the first color in a pixel repeating unit on the third pixel row (the (i + 2)-th row);

[0139] According to the above, when inputting data signals to at least two adjacent pixel rows corresponding to the target driving row in response to the line scanning signal, a virtual display pixel is formed by different pixel repeating units on at least three adjacent pixel rows.

[0140] By adopting the display panel described in the embodiments of the present disclosure, through arranging sub-pixels of a first color to be non-uniform in the second display area and performing brightness modulation on the sub-pixels of the second color and the sub-pixels of the third color, uniform distribution of the brightness center of virtual pixels can be achieved.

[0141] In addition, for the display panel described in the embodiments of the present disclosure, adjacent two pixel repeating units share adjacent sub-pixels of the second color and the sub-pixels of the third color (such as R sub-pixels or B sub-pixels), thereby adding virtual display pixels on the basis of normal physical pixels. In this way, 2 physical pixels become 3 pixel units in visual perception, so the resolution is increased by 1.5 times compared with a normal display panel, achieving an increase in the resolution of the second display area, that is, the area corresponding to the camera, and reducing the difference in display effects compared with the first display area.

[0142] For example, in order 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. If the setting density of pixel units of a conventional OLED display panel is 720p, the setting density of pixel units in the second display area is 180p. By adopting the display panel described in the embodiments of the present disclosure and using the above-mentioned SPR driving algorithm, the actually viewed resolution on the second display area can reach 270p, so that the display effect can be ensured while meeting the light transmission requirements of the display area corresponding to the under-screen camera module.
