DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0054] The embodiments of the present disclosure provide a display substrate, a display method thereof, a display device, and a high-precision metal mask. In order to make the objectives, technical solutions, and advantages of the present disclosure clearer, the present disclosure will be described in more detail below with reference to the drawings. It should be apparent that the described embodiments are only a part of the embodiments of the present disclosure, and are not all of the embodiments. All other embodiments that a person skilled in the art can conceive based on the embodiments in the present disclosure without requiring creative efforts are within the scope of the present disclosure.

[0055] The shapes and sizes of each component in the drawings are not to scale but are merely intended to diagrammatically illustrate the contents of the present disclosure.

[0056] In a display substrate according to an embodiment of the present disclosure, as shown in Figures 1a to 1i, a display region of the display substrate includes a first display sub-region A1 and a second display sub-region A2, and as shown in Figures 2 to 7, a plurality of evenly distributed sub-pixels are disposed in the second display sub-region A2. The pixel distribution density in the first display sub-region A1 is greater than the pixel distribution density in the second display sub-region A2.

[0057] In the display substrate according to the embodiment of the present disclosure, the display region is configured as a first display sub-region with a large pixel distribution density (i.e., high resolution) and a second display sub-region with a small pixel distribution density (i.e., low resolution). Since the pixel distribution density in the second display sub-region is small, elements such as a camera, a sensor, and a microphone can be installed in the second display sub-region, that is, the screen occupancy rate of the display substrate is improved by improving the light transmittance of the screen by reducing the local pixel distribution density. Moreover, since the sub-pixels in the second display sub-region are evenly distributed, the uniformity of the luminance distribution in the second display sub-region can be ensured.

[0058] The pixel distribution density refers to the number of pixels evenly distributed in a unit area. The more pixels there are in a unit area, the higher the pixel distribution density and the higher the resolution. Conversely, the fewer the number of pixels in a unit area, the lower the pixel distribution density and the lower the resolution.

[0059] Furthermore, in the embodiment of the present disclosure, the calculation formula for pixel distribution density is specifically as follows:

[0060]

number

[0061] (wherein ρ represents pixel distribution density, x represents the number of display pixels in the row direction, y represents the number of display pixels in the column direction, and S represents the screen area.)

[0062] In a specific embodiment, in the display substrate according to the embodiment of the present disclosure, the second display sub-region may be one or more, and the first display sub-region may be a continuous region, or the first display sub-region may be a discontinuous region, which can be designed according to the actual application scenario and is not limited herein.

[0063] In a specific embodiment, in a display substrate according to an embodiment of the present disclosure, as shown in Figures 1a to 1g, at least some of the sides of the second display sub-region A2 overlap with at least some of the sides of the display region, and the remaining part of the second display sub-region A2 is surrounded by the first display sub-region A1, so that the second display sub-region A2 can be disposed at the edge of the display region.

[0064] In a specific embodiment, in a display substrate according to an embodiment of the present disclosure, the first display sub-region A1 is disposed surrounding the second display sub-region A2, as shown in Figures 1h and 1i, so that the second display sub-region A2 can be disposed inside the display region.

[0065] Furthermore, in certain embodiments, the second display sub-region A2 may be arranged in a regular shape, for example, as shown in FIG. 1a to FIG. 1c, the second display sub-region A2 may be arranged in a rectangular shape. The apex angle of the rectangular shape may be a right angle or an arched angle. As shown in FIG. 1d, the second display sub-region A2 may be arranged in a trapezoid shape. The apex angle of the trapezoid may be a general included angle or an arched angle. As shown in FIG. 1h and FIG. 1i, the second display sub-region A2 may be arranged in a circular shape. Needless to say, the second display sub-region A2 may be arranged in an irregular shape. For example, as shown in FIG. 1e, the second display sub-region A2 may be arranged in a water drop shape. Of course, in practical application, the shape of the second display sub-region may be designed according to the shape of the element arranged in the second display sub-region, and is not limited here.

[0066] Optionally, in the display substrate according to the embodiment of the present disclosure, the first display sub-region A1 and the second display sub-region A2 may form a continuous display region, and the shape of the display region may be substantially rectangular, as shown in Figures 1a-1i. In this manner, the continuous display region is formed by forming the first display sub-region A1 and the second display sub-region A2 into complementary shapes. Furthermore, if the apex angles of the display region are all right angles, the display region will be rectangular. Alternatively, if the apex angles of the display region are arched angles, the shape of the display region will be substantially rectangular.

[0067] In a specific embodiment, in the display substrate according to the embodiment of the present disclosure, the relative positional relationship and shape of the first display sub-region and the second display sub-region are not limited, and may be installed according to the screen design of the display substrate. Taking a mobile phone as an example, as shown in FIG. 1a, the second display sub-region A2 may be installed in the upper left corner of the first display sub-region A1. As shown in FIG. 1b, the second display sub-region A2 is installed in the upper right corner of the first display sub-region A1. As shown in FIG. 1c to FIG. 1e, the second display sub-region A2 is installed above the center of the first display sub-region A1. As shown in FIG. 1f, the first display sub-region A1 and the second display sub-region A2 may be arranged along the row direction. Here, the second display sub-region A2 may be located above or below the first display sub-region A1. In this way, a sensor, for example, a sensor (e.g., an infrared sensor, etc.) that performs face recognition may be installed in the area where the second display sub-region A2 is located. As shown in FIG. 1g, the first display sub-region A1 and the second display sub-region A2 are arranged along the column direction. Here, the second display sub-region A2 may be located on the left or right side of the first display sub-region A1. In this way, a sensor, for example, a sensor for performing face recognition (e.g., an infrared sensor, etc.) may be installed in the area where the second display sub-region A2 is located. As shown in FIG. 1h, the second display sub-region A2 is installed in the center of the first display sub-region A1. As shown in FIG. 1i, the second display sub-region A2 is installed in a corner (e.g., the upper left corner) of the display region. Of course, in practical application, the position of the second display sub-region A2 may be specifically designed according to the practical application scene, and is not limited here.

[0068] Optionally, in the display substrate according to the embodiment of the present disclosure, the pixel distribution density of the second display sub-region is generally set to 1 / 2 to 1 / 8 of the pixel distribution density of the first display sub-region. In a specific embodiment, the pixel distribution density in the second display sub-region is determined according to the elements to be set in the second display sub-region and the display needs, and is not limited here. For example, take the case where a camera is installed in the second display sub-region as an example, if the pixel distribution density is too large, it can ensure a good display effect but will have a negative impact on the clarity of the image, and if the pixel distribution density is too small, it can ensure high clarity of the image but will impair the display.

[0069] In certain embodiments, even at resolutions achievable with conventional display substrates, the pixel distribution density of the second display sub-region is typically at least ¼ of the pixel distribution density of the first display sub-region. For example, the pixel distribution density of the second display sub-region is about ½, ⅓ or ¼ of the pixel distribution density of the first display sub-region. Of course, the higher the resolution of the display substrate, the smaller the ratio of the pixel distribution density of the second display sub-region to the pixel distribution density of the first display sub-region can be set.

[0070] In a specific embodiment, in a display substrate according to an embodiment of the present disclosure, the area of ​​the second display sub-region A2 can be smaller than the area of ​​the first display sub-region A1, as shown in Figures 1a to 1i. Of course, in practical application, the area of ​​the second display sub-region can be designed according to the elements installed in the second display sub-region, and is not limited here.

[0071] In general, a pixel unit is provided in a display region, and a plurality of sub-pixels are provided in the pixel unit. A pixel in the embodiment of the present disclosure may be a combination of sub-pixels capable of independently displaying one pixel point, for example, one pixel may be one pixel unit. In the display substrate according to the embodiment of the present disclosure, as shown in Figs. 2 to 7, the second display sub-region A2 may include a plurality of first sub-pixels 1, a plurality of second sub-pixels 2, and a plurality of third sub-pixels 3, and the centers of the sub-pixels of the same color may be evenly distributed. That is, the centers of the first sub-pixels 1 are evenly distributed, the second sub-pixels 2 are evenly distributed, and the third sub-pixels 2 are evenly distributed. The uniformity of the display is ensured.

[0072] Optionally, in a display substrate according to an embodiment of the present disclosure, sub-pixels of the same color may be arranged at equal intervals in the row direction, and sub-pixels of the same color may be arranged at equal intervals in the column direction, as shown in Figures 2 to 7.

[0073] Optionally, in the display substrate according to the embodiment of the present disclosure, the sub-pixels of the same color in adjacent rows may be staggered, and the centers of two adjacent sub-pixels of the same color in the same row are equidistant from the centers of adjacent sub-pixels of the same color in the adjacent rows, as shown in Figures 2 to 5 and 7. Taking Figure 4 as an example, in the second display sub-region A2, the first first sub-pixel 1 in the second row is located on the connecting line between the centers of the first and second first sub-pixels 1 in the first row.

[0074] Optionally, in a display substrate according to an embodiment of the present disclosure, sub-pixels of the same color in adjacent columns may be staggered, and the centers of two adjacent sub-pixels of the same color in the same column are equidistant from the centers of adjacent sub-pixels of the same color in the adjacent columns, as shown in Figures 2 to 5 and 7. Taking Figure 4 as an example, in the second display sub-region A2, the first first sub-pixel 1 in the first column is on the central connecting line between the first and second first sub-pixels 1 in the second column.

[0075] However, deviations may occur due to limitations in process conditions or other factors, such as the placement of wiring or vias, and therefore, as long as the position and relative positional relationship of each subpixel roughly satisfies the above conditions, it falls within the scope of the present disclosure.

[0076] In a display substrate according to an embodiment of the present disclosure, as shown in Figures 2 to 7, first sub-pixels 1, second sub-pixels 2, and third sub-pixels 3 are arranged in the second display sub-region A2, and the first sub-pixels 1 may be evenly distributed in the second display sub-region A2, the second sub-pixels 2 may be evenly distributed in the second display sub-region A2, and the third sub-pixels 3 may be evenly distributed in the second display sub-region A2.

[0077] In the display substrate according to the embodiment of the present disclosure, the first sub-pixel 1, the second sub-pixel 2 and the third sub-pixel 3 may be uniformly distributed in the row direction, as shown in FIGS.

[0078] In the display substrate according to the embodiment of the present disclosure, as shown in FIGS. 2 to 7, the second display sub-region A2 includes a plurality of third pixel units 30 arranged in a matrix, and each third pixel unit 30 includes a first sub-pixel 1, a second sub-pixel 2, and a third sub-pixel 3. In the same third pixel unit 30, the first sub-pixel 1 and the third sub-pixel 3 may be disposed adjacent to each other in the same row, and the second sub-pixel 2 may be disposed in a row adjacent to the row in which the first sub-pixel 1 and the third sub-pixel 3 are disposed. In this way, in the second display sub-region A2, the three sub-pixels in the third pixel unit 30 are arranged in a triangular shape. Taking the third pixel unit 30 in the first row as an example, the first sub-pixel 1 and the third sub-pixel 3 in the third pixel unit 30 are disposed in the first row of the sub-pixel rows, and the second sub-pixel 2 is disposed in the second row of the sub-pixel rows.

[0079] Optionally, in a display substrate according to an embodiment of the present disclosure, the centers of the first, second and third sub-pixels of the same color in the second display sub-region may be evenly distributed. For example, as shown in Figures 2 to 7, the centers of the first sub-pixels 1 in the second display sub-region A2 are evenly distributed. The centers of the second sub-pixels 2 in the second display sub-region A2 are evenly distributed. The centers of the third sub-pixels 3 in the second display sub-region A2 are evenly distributed.

[0080] Optionally, in a display substrate according to an embodiment of the present disclosure, for subpixels of the same color among the first, second and third subpixels in the second display subregion, the subpixels may be arranged at equal intervals in the row direction and at equal intervals in the column direction. For example, as shown in FIGS. 2 to 7, the first subpixels 1 in the second display subregion A2 are arranged at equal intervals in the row direction and at equal intervals in the column direction. The second subpixels 2 in the second display subregion A2 are arranged at equal intervals in the row direction and at equal intervals in the column direction. The third subpixels 3 in the second display subregion A2 are arranged at equal intervals in the row direction and at equal intervals in the column direction.

[0081] Optionally, in the display substrate according to the embodiment of the present disclosure, for sub-pixels of the same color among the first, second and third sub-pixels in the second display sub-region, the sub-pixels may be arranged in a staggered manner in adjacent rows, and the centers of two adjacent sub-pixels in the same row are equidistant from the centers of the nearest same sub-pixels in the respective adjacent rows. For example, as shown in Figures 2 to 7, the first sub-pixels 1 in the second display sub-region A2 are arranged in a staggered manner in adjacent rows, and the centers of two adjacent first sub-pixels 1 in the same row are equidistant from the centers of the nearest same first sub-pixels 1 in the respective adjacent rows. The rest is similar and will not be described in detail here.

[0082] Optionally, in the display substrate according to the embodiment of the present disclosure, for sub-pixels of the same color among the first, second and third sub-pixels in the second display sub-region, the sub-pixels may be arranged in a staggered manner in adjacent columns, and the centers of two adjacent sub-pixels in the same column are equidistant from the centers of the nearest same sub-pixels in the respective adjacent columns. For example, as shown in Figures 2 to 7, the first sub-pixels 1 in the second display sub-region A2 are arranged in a staggered manner in adjacent columns, and the centers of two adjacent first sub-pixels 1 in the same column are equidistant from the centers of the nearest same first sub-pixels 1 in the respective adjacent columns. The rest is similar and will not be described in detail here.

[0083] Optionally, in the display substrate according to the embodiment of the present disclosure, the sub-pixels of the third pixel units 30 in the same column in the second display sub-region A2 may be arranged in the same manner, as shown in Figures 2, 3 and 5 to 7. In this way, the arrangement of the third pixel units 30 in each column in the column direction is the same, and display uniformity is ensured.

[0084] Optionally, in the display substrate according to the embodiment of the present disclosure, in the second display sub-region A2, the sub-pixel arrangement manners of two adjacent third pixel units 30 in the same column may be opposite, as shown in Fig. 4. Taking the third pixel unit 30 in the first row and the third pixel unit 30 in the second row in the same column as an example, the third pixel unit 30 in the first row forms a triangle in the order of the third sub-pixel 3, the first sub-pixel 1, and the second sub-pixel 2. The third pixel unit 30 in the second row forms a triangle in the order of the first sub-pixel 1, the third sub-pixel 3, and the second sub-pixel 2.

[0085] Optionally, in the display substrate according to the embodiment of the present disclosure, as shown in Figures 2 to 7, in the second display sub-region A2, in the third pixel unit 30, the distance between the centers of the second sub-pixel 2 and the first sub-pixel 1 may be equal to the distance between the centers of the second sub-pixel 2 and the third sub-pixel 3. That is, in the third pixel unit 30, the centers of the second sub-pixel 2, the first sub-pixel 1, and the third sub-pixel 3 form an isosceles triangle. Thus, the light-emitting center of the pixel of the third pixel unit 30 is at the center of the isosceles triangle.

[0086] Optionally, in the display substrate according to the embodiment of the present disclosure, as shown in FIG. 2 to FIG. 7, for two third pixel units 30 adjacent to each other along the row direction in the second display sub-region A2, the first sub-pixel 1 and the third sub-pixel 3 in one third pixel unit 30 and the second sub-pixel 2 in the other third pixel unit 30 may be arranged in the same row. In this way, when displaying, the number of pixels in the second display sub-region A2 is equal to the number of the third pixel units 30. That is, the physical resolution of the pixels in the second display sub-region A2 is the display resolution. In addition, in the third pixel unit 30 in the second display sub-region A2, three sub-pixels are arranged in a triangular shape, and among the two third pixel units 30 adjacent to each other along the row direction, one is an inverted triangle and the other is a normal triangle, thereby avoiding a situation in which the number of sub-pixels in some rows is large and the number of sub-pixels in other rows is small in the second display sub-region A2, and preventing uneven display.

[0087] Optionally, in the display substrate according to the embodiment of the present disclosure, the sub-pixels in the second display sub-region A2 may be arranged uniformly and in a checkerboard pattern, as shown in FIGS.

[0088] Optionally, in the display substrate according to the embodiment of the present disclosure, as shown in FIG. 4, in the same third pixel unit 30 in the second display sub-region A2, the orthogonal projection of the center of the second sub-pixel 2 on the connecting line between the center of the first sub-pixel 1 and the center of the third sub-pixel 3 may be between the center of the first sub-pixel 1 and the center of the third sub-pixel 3. For example, the orthogonal projection of the center of the second sub-pixel 2 on the connecting line L1 between the center of the first sub-pixel 1 and the center of the third sub-pixel 3 is at the intersection point of the connecting line L1 and the straight line L2. In this way, the distance between the center of the second sub-pixel 2 and the center of the first sub-pixel 1 in the third pixel unit 30 is equal to the distance between the center of the second sub-pixel 2 and the center of the third sub-pixel 3, so that the three sub-pixels are arranged in an isosceles triangle shape, and vertical bright and dark stripes are avoided in the second display sub-region A2.

[0089] In certain embodiments, the distance between the center of the second subpixel and the center of the first subpixel and the distance between the center of the second subpixel and the center of the third subpixel may not be exactly the same, and in an actual process, deviations may occur due to limitations in process conditions or other factors, such as the placement of wiring or vias; therefore, as long as the shape, position and relative positional relationship of each subpixel roughly satisfy the above conditions, it falls within the patent scope of the present disclosure.

[0090] Optionally, in the display substrate according to the embodiment of the present disclosure, sub-pixels of the same color may not be adjacent in the third pixel units 30 adjacent along the row direction, as shown in FIGS. 2 to 5 and 7. That is, in two third pixel units 30 adjacent along the row direction, the first sub-pixel 1 in one third pixel unit 30 and the first sub-pixel 1 in the other third pixel unit 30 are not adjacent. In this way, the phenomenon of color bias caused by the sub-pixels of two adjacent columns having similar colors in the second display sub-region A2 is avoided. Of course, as shown in FIG. 6, sub-pixels of the same color may be adjacent in the third pixel units 30 adjacent along the row direction. That is, in two third pixel units 30 adjacent along the row direction, the third sub-pixel 3 in one third pixel unit 30 and the third sub-pixel 3 in the other third pixel unit 30 are adjacent.

[0091] Optionally, in the display substrate according to the embodiment of the present disclosure, as shown in Figures 2 to 7, in the second display sub-region A2, the light-emitting areas of one first sub-pixel 1, one second sub-pixel 2 and one third sub-pixel 3 may be substantially the same. In this way, the light emission can be made uniform. Of course, in certain embodiments, since the light-emitting efficiencies of different sub-pixels are different, the light-emitting areas of the first sub-pixel 1, the second sub-pixel 2 and the third sub-pixel 3 may be different in the second display sub-region A2, and are not limited here.

[0092] Optionally, in the display substrate according to the embodiment of the present disclosure, in the second display sub-region A2, one first sub-pixel 1, one second sub-pixel 2 and one third sub-pixel 3 may be substantially identical in shape, as shown in Figures 2 to 7. In this way, the process difficulty can be reduced.

[0093] Optionally, in the display substrate according to the embodiment of the present disclosure, as shown in FIGS. 2 to 7, the first display sub-region A1 may include a plurality of first pixel units 10 and second pixel units 20 arranged adjacent to each other, where the first pixel unit 10 includes a first sub-pixel 1 and a second sub-pixel 2, and the second pixel unit 20 includes a third sub-pixel 3 and a second sub-pixel 2. When displaying, the number of pixels in the first display sub-region A1 is equal to the sum of the number of the first pixel units 10 and the number of the second pixel units 20. That is, the pixel arrangement in the first display sub-region A1 is a pentile arrangement, and when displaying, a pixel unit can realize a higher resolution than the physical resolution by utilizing sub-pixels in an adjacent pixel unit.

[0094] In a specific embodiment, in a display panel according to an embodiment of the present disclosure, when two pixel units are adjacent to each other, it means that there is no other pixel unit between the two pixel units, and when two sub-pixels are adjacently disposed, it means that there is no other sub-pixel between the two sub-pixels.

[0095] In addition, in the display panel according to the embodiment of the present disclosure, since the space at the edge of the display sub-region is limited, the arrangement of sub-pixels in the first display sub-region and the arrangement of sub-pixels in the second display sub-region mainly refer to the inside of the display sub-region, and at the edge of the display sub-region, the arrangement of some sub-pixels may differ from other regions, and is not limited here.

[0096] In a specific embodiment, the first, second and third subpixels are generally one of red, green and blue subpixels, respectively. In a display substrate according to an embodiment of the present disclosure, the second subpixel may be a green subpixel, the first subpixel may be a red or blue subpixel, and the third subpixel may be a blue or red subpixel.

[0097] In addition, in the display panel according to the embodiment of the present disclosure, the center of the subpixel is the center of the light-emitting region of the subpixel. Taking an organic light-emitting diode (OLED) display panel as an example, the subpixel generally includes a laminated structure composed of an anode layer, a light-emitting layer, and a cathode layer, and when displaying, the light-emitting region corresponding to the laminated structure becomes the light-emitting region of the subpixel. In this way, the area occupied by the light-emitting region can be the light-emitting area. Of course, the light-emitting area may be, for example, the area occupied by an opening region defined by a pixel definition layer, and is not limited here.

[0098] In a specific embodiment, in a display substrate according to an embodiment of the present disclosure, as shown in FIGS. 2 to 7, in the first display sub-region A1, the first pixel unit 10 and the second pixel unit 20 may be arranged in any Pentile arrangement manner, which is not limited here.

[0099] Optionally, in a display substrate according to an embodiment of the present disclosure, in the first display sub-region A1, the first pixel units 10 and the second pixel units 20 may be arranged alternately in the column direction, and the first pixel units 10 and the second pixel units 20 may be arranged alternately in the row direction, as shown in Figures 2 to 7.

[0100] Optionally, in the display substrate according to the embodiment of the present disclosure, as shown in FIG. 2 and FIG. 3, in the first display sub-region A1, in the first pixel unit 10, the second sub-pixel 2 and the first sub-pixel 1 may be arranged in the same row, and in the second pixel unit 20, the second sub-pixel 2 and the third sub-pixel 3 may be arranged in the same row. In addition, for the first pixel unit 10 and the second pixel unit 20 adjacent to each other along the row direction, the second sub-pixel 2 in the first pixel unit 10 and the second sub-pixel 2 in the second pixel unit 20 are not adjacent to each other. For example, for the first pixel unit 10 and the second pixel unit 20 adjacent to each other along the row direction, the third sub-pixel 3 is sandwiched between the second sub-pixel 2 in the first pixel unit 10 and the second sub-pixel in the second pixel unit 20. Of course, the above embodiment may have other embodiments, which will not be described in detail here.

[0101] Optionally, in a display substrate according to an embodiment of the present disclosure, as shown in Figures 2 and 3, within the first display sub-region A1, the emitting area of ​​one first sub-pixel 1, the emitting area of ​​one second sub-pixel 2 and the emitting area of ​​one third sub-pixel 3 may be approximately the same.

[0102] 2 and 3, for each of the first pixel units 10 and each of the second pixel units 20 in the same column, the second sub-pixel 2 in each of the first pixel units 10 and the second sub-pixel 2 in each of the second pixel units 20 are in the same column. For example, taking the first column as an example, the second sub-pixel 2 in each of the first pixel units 10 and the second sub-pixel 2 in each of the second pixel units 20 are in the same column.

[0103] Furthermore, in a display substrate according to an embodiment of the present disclosure, as shown in FIGS. 2 and 3, in a first display sub-region A1, a first sub-pixel 1, a second sub-pixel 2, and a third sub-pixel 3 may have substantially the same shape. In the first display sub-region A1, the first sub-pixel 1 may have a rectangular shape. In the first display sub-region A1, the second sub-pixel 2 may have a rectangular shape. In the first display sub-region A1, the third sub-pixel 3 may have a rectangular shape.

[0104] Optionally, in the display substrate according to the embodiment of the present disclosure, as shown in FIGS. 4 to 7, in the first display sub-region A1, in the first pixel unit 10, the second sub-pixel 2 and the first sub-pixel 1 may be arranged in the same row, and in the second pixel unit 20, the second sub-pixel 2 and the third sub-pixel 3 may be arranged in a shifted row and a shifted column. In the first pixel unit 10 and the second pixel unit 20 adjacent to each other along the row direction, the two second sub-pixels 2 are not adjacent to each other. The first pixel unit 10 and the second pixel unit 20 adjacent to each other along the column direction are one pixel group 100, and in the same pixel group 100, the second sub-pixel 2 in the first pixel unit 10 and the second sub-pixel 2 in the second pixel unit 20 are in the same column. That is, the pixel units in two adjacent rows are shifted by half a column in the column direction.

[0105] 4 to 7, in the display substrate according to the embodiment of the present disclosure, in the same pixel group 100, two second sub-pixels 2 are arranged adjacent to each other along the column direction, and the two second sub-pixels 2 are symmetrical with respect to the row direction, that is, the two second sub-pixels 2 in the same pixel group 100 are arranged in a mirrored manner. Furthermore, in the first display sub-region A1, when the second sub-pixels 2 are green sub-pixels, the light-emitting area of ​​the two second sub-pixels 2 is smaller than the light-emitting area of ​​one first sub-pixel 1, and the light-emitting area of ​​the two second sub-pixels 2 is smaller than the area of ​​one third sub-pixel 3, because the light-emitting efficiency of the green sub-pixel is higher than the light-emitting efficiency of the sub-pixels of other colors.

[0106] As an option, in a display substrate according to an embodiment of the present disclosure, as shown in Figures 4 to 7, in the first display sub-region A1, two adjacent second sub-pixels 2 along the column direction may be grouped into one second sub-pixel group 200, and the distance between the two adjacent second sub-pixel groups 200 along the column direction in the first display sub-region A1 may be equal to the distance between two adjacent second sub-pixels 2 along the column direction in the second display sub-region A2.

[0107] Optionally, in a display substrate according to an embodiment of the present disclosure, as shown in Figures 4 to 7, in the same pixel group 100, the shapes of the first sub-pixel 1 and the third sub-pixel 3 may be the same, and the shape of the combination of two adjacent second sub-pixels 2 along the column direction may be the same as the shape of the first sub-pixel 1.

[0108] Optionally, in a display substrate according to an embodiment of the present disclosure, in the first display sub-region A1, the first sub-pixel 1 and the third sub-pixel 3 may all be hexagonal in shape, and the second sub-pixel 2 may be pentagonal in shape, as shown in Figures 4 to 7. In this way, two second sub-pixels 2 adjacent to each other in the column direction may be combined to form a single hexagon.

[0109] Specifically, in the display substrate according to the embodiment of the present disclosure, in the first display sub-region, the first sub-pixel, the second sub-pixel and the third sub-pixel are not limited in shape and may be regular or irregular, and in certain embodiments, a regular shape is generally preferred for ease of process implementation.

[0110] Specifically, in the display substrate according to the embodiment of the present disclosure, in the second display sub-region, the first sub-pixel, the second sub-pixel and the third sub-pixel are not limited in shape and may be regular or irregular, and in certain embodiments, a regular shape is generally preferred for ease of process implementation.

[0111] Optionally, in the display substrate according to the embodiment of the present disclosure, the interval between two adjacent first subpixels along the column direction in the first display subregion may be equal to or smaller than the interval between two adjacent first subpixels along the column direction in the second display subregion. The interval between two adjacent third subpixels along the column direction in the first display subregion is equal to or smaller than the interval between two adjacent third subpixels along the column direction in the second display subregion. For example, as shown in FIG. 2, FIG. 3 and FIG. 5 to FIG. 7, the interval between two adjacent first subpixels 1 along the column direction in the first display subregion A1 is approximately equal to the interval between two adjacent first subpixels 1 along the column direction in the second display subregion A2. The interval between two adjacent third subpixels 3 along the column direction in the first display subregion A1 is approximately equal to the interval between two adjacent third subpixels 3 along the column direction in the second display subregion A2. 4, the distance between two first subpixels 1 adjacent to each other along the column direction in the first display subregion A1 is smaller than the distance between two first subpixels 1 adjacent to each other along the column direction in the second display subregion A2. The distance between two third subpixels 3 adjacent to each other along the column direction in the first display subregion A1 is smaller than the distance between two third subpixels 3 adjacent to each other along the column direction in the second display subregion A2.

For example, as shown in Figures 2 and 3, the light-emitting area of ​​one second sub-pixel 2 in the second display sub-region A2 is approximately equal to the light-emitting area of ​​one second sub-pixel 2 in the first display sub-region A1, the light-emitting area of ​​one first sub-pixel 1 in the second display sub-region A2 is approximately equal to the light-emitting area of ​​one first sub-pixel 1 in the first display sub-region A1, and the light-emitting area of ​​one third sub-pixel 3 in the second display sub-region A2 is approximately equal to the light-emitting area of ​​one third sub-pixel 3 in the first display sub-region A1. As shown in Figures 4 to 7, the light-emitting area of ​​one second sub-pixel 2 in the second display sub-region A2 is larger than the light-emitting area of ​​one second sub-pixel 2 in the first display sub-region A1, the light-emitting area of ​​one first sub-pixel 1 in the second display sub-region A2 is approximately equal to the light-emitting area of ​​one first sub-pixel 1 in the first display sub-region A1, and the light-emitting area of ​​one third sub-pixel 3 in the second display sub-region A2 is approximately equal to the light-emitting area of ​​one third sub-pixel 3 in the first display sub-region A1.

In this way, the process difficulty can be reduced.

[0114] Optionally, in a display substrate according to an embodiment of the present disclosure, as shown in Figures 2 to 7, within the first display sub-region A1, the light-emitting area of ​​one first sub-pixel 1 may be approximately equal to the light-emitting area of ​​one third sub-pixel 3.

[0115] Optionally, in the display substrate according to the embodiment of the present disclosure, in the first display sub-region, the light-emitting area of ​​one second sub-pixel may be equal to or smaller than the light-emitting area of ​​one first sub-pixel, and the light-emitting area of ​​one second sub-pixel may be equal to or smaller than the light-emitting area of ​​one third sub-pixel. For example, as shown in FIG. 2 and FIG. 3, in the first display sub-region A1, the light-emitting area of ​​one second sub-pixel 2 is approximately equal to the light-emitting area of ​​one first sub-pixel 1, and the light-emitting area of ​​one second sub-pixel 2 is approximately equal to the light-emitting area of ​​one third sub-pixel 3.

[0116] Optionally, in the display substrate according to the embodiment of the present disclosure, the sub-pixels in the second display sub-region A2 may be in the same row as some of the sub-pixels in the first display sub-region A1, as shown in Figures 2 and 3. That is, the sub-pixels in the second display sub-region A2 are not offset from the sub-pixels in the first display sub-region A1 in the row direction, but correspond to them, thereby ensuring that the sub-pixels in the second display sub-region A2 and the sub-pixels in the first display sub-region A1 maintain consistency in the row direction, which is advantageous for wiring the display substrate.

[0117] Optionally, in a display substrate according to an embodiment of the present disclosure, the sub-pixels in the second display sub-region A2 may be in the same column as some of the sub-pixels in the first display sub-region A1, as shown in Figures 4 to 7. That is, the sub-pixels in the second display sub-region A2 are not offset in the column direction from the sub-pixels in the first display sub-region A1, but correspond to them, thereby ensuring that the sub-pixels in the second display sub-region A2 and the sub-pixels in the first display sub-region A1 maintain consistency in the column direction, which is advantageous for wiring the display substrate.

[0118] Optionally, in the display substrate according to the embodiment of the present disclosure, the first subpixel in the second display subregion and the first subpixel in the first display subregion may be in at least one of the same column and the same row. For example, as shown in FIG. 6 and FIG. 7, the first subpixel 1 in the second display subregion A2 and the first subpixel 1 in the first display subregion A1 are in the same column, thereby ensuring that the first subpixel 1 in the second display subregion A2 and the first subpixel 1 in the first display subregion A1 are consistent in the column direction. As shown in FIG. 2 and FIG. 3, the first subpixel 1 in the second display subregion A2 and the first subpixel 1 in the first display subregion A1 are in the same row, thereby ensuring that the first subpixel 1 in the second display subregion A2 and the first subpixel 1 in the first display subregion A1 are consistent in the row direction.

For example, as shown in FIG. 2 and FIG. 3, the second sub-pixel 2 in the second display sub-region A2 and the second sub-pixel 2 in the first display sub-region A1 are in the same row. As shown in FIG. 4 to FIG. 7, the second sub-pixel 2 in the second display sub-region A2 and the second sub-pixel 2 in the first display sub-region A1 are in the same column. This ensures that the second sub-pixel 2 in the second display sub-region A2 and the second sub-pixel 2 in the first display sub-region A1 maintain consistency in the column direction. In addition, in the display substrate, the second sub-pixel 2 is the center of the light-emitting pixel of the pixel unit, so that the center of the light-emitting pixel in the second display sub-region and the center of the light-emitting pixel in the first display sub-region maintain consistency in the row direction. Of course, the second subpixel in the second display subregion and the second subpixel in the first display subregion may be in the same column, and the second subpixel in the second display subregion and the second subpixel in the first display subregion may be in the same row.

[0120] Optionally, in the display substrate according to the embodiment of the present disclosure, the third sub-pixel in the second display sub-region and the third sub-pixel in the first display sub-region may be in at least one of the same column and the same row. For example, as shown in FIG. 6 and FIG. 7, the third sub-pixel 3 in the second display sub-region A2 and the third sub-pixel 3 in the first display sub-region A1 are in the same column, thereby ensuring that the third sub-pixel 3 in the second display sub-region A2 and the third sub-pixel 3 in the first display sub-region A1 maintain consistency in the column direction. As shown in FIG. 2 and FIG. 3, the third sub-pixel 3 in the second display sub-region A2 and the third sub-pixel 3 in the first display sub-region A1 are in the same row, thereby ensuring that the third sub-pixel 3 in the second display sub-region A2 and the third sub-pixel 3 in the first display sub-region A1 maintain consistency in the row direction. Of course, the third subpixel in the second display subregion and the third subpixel in the first display subregion may be in the same column, and the third subpixel in the second display subregion and the third subpixel in the first display subregion may be in the same row.

[0121] Optionally, in the display substrate according to the embodiment of the present disclosure, as shown in FIGS. 5 to 7 , a distance between two adjacent first sub-pixels 1 in the first display sub-region A1 along the column direction is equal to a distance between two adjacent first sub-pixels 1 in the second display sub-region A2 along the column direction; a distance between two adjacent third sub-pixels 3 along the column direction in the first display sub-region A1 is equal to a distance between two adjacent third sub-pixels 3 along the column direction in the second display sub-region A2; In the first display sub-region A1, two second sub-pixels 2 adjacent to each other along the column direction may be grouped into one second sub-pixel group 200, and the distance between two second sub-pixel groups 200 adjacent to each other along the column direction in the first display sub-region A1 may be equal to the distance between two second sub-pixels 2 adjacent to each other along the column direction in the second display sub-region A2.

[0122] Optionally, in a display substrate according to an embodiment of the present disclosure, as shown in Figures 4 to 7, the row-wise distribution density of the first sub-pixels 1 in the second display sub-region A2 may be approximately 1 / 2 of the row-wise distribution density of the first sub-pixels 1 in the first display sub-region A1, or of course, other ratios, such as 1 / 3, 1 / 4, etc., may be used and are not limited thereto.

[0123] The row-direction distribution density of the third sub-pixels 3 in the second display sub-region A2 is approximately 1 / 2 of the row-direction distribution density of the third sub-pixels 3 in the first display sub-region A1, and of course other ratios, such as 1 / 3, 1 / 4, etc., may be used, and are not limited here.

[0124] The row-direction distribution density of the second sub-pixels 2 in the second display sub-region A2 is approximately 1 / 4 of the row-direction distribution density of the second sub-pixels 2 in the first display sub-region A1, and of course other ratios, such as 1 / 6, 1 / 9, etc., may be used, and are not limited here.

[0125] Note that the row direction here refers to a row of subpixels as a unit, and the density ratios according to the embodiments of the present disclosure are all within approximate ratio ranges, and in certain embodiments, the density ratios may not be integers.

[0126] Optionally, in a display substrate according to an embodiment of the present disclosure, as shown in Figures 4 to 7, in the first display sub-region A1, the light-emitting area of ​​the second sub-pixel 2 may be smaller than that of the first sub-pixel 1, and the light-emitting area of ​​the second sub-pixel 2 may be smaller than that of the third sub-pixel 3. This is because, in the first display sub-region A1, while the number of the first sub-pixels 1 is the same as the number of the third sub-pixels 3, the number of the second sub-pixels 2 is one time that of the first sub-pixels 1, and therefore the light-emitting area of ​​the second sub-pixels 2 can be made smaller.

[0127] In addition, the term "having the same shape" means that the shapes of the light-emitting regions of the sub-pixels are similar, and the areas may be the same or different. The light-emitting areas of the sub-pixels may be set according to the light-emitting efficiency of the sub-pixels, and are not limited here.

[0128] In the display panel according to the embodiment of the present disclosure, the shape of the sub-pixel refers to the shape of the light-emitting region of the sub-pixel.

[0129] In a specific embodiment, in a display substrate according to an embodiment of the present disclosure, as shown in Figures 4 to 7, in a first display sub-region A1, when the second sub-pixel 2 is a green sub-pixel, the light-emitting area of ​​two second sub-pixels 2 is smaller than the light-emitting area of ​​one first sub-pixel 1, and the light-emitting area of ​​two second sub-pixels 2 is smaller than the area of ​​one third sub-pixel 3, because the light-emitting efficiency of the green sub-pixel is higher than the light-emitting efficiency of sub-pixels of other colors.

[0130] Based on the same inventive concept, the embodiment of the present disclosure further provides a display device including any one of the above display substrates according to the embodiment of the present disclosure. The display device may be any product or component having a display function, such as a mobile phone, a tablet, a television, a display, a notebook computer, a digital photo frame, a navigator, etc. For the implementation of the display device, reference may be made to the embodiment of the above display substrate, and redundant description will be omitted here.

[0131] Based on the same inventive concept, an embodiment of the present disclosure further provides a high-precision metal mask configured to manufacture any one of the above display substrates according to an embodiment of the present disclosure, the high-precision metal mask including a plurality of opening areas corresponding to the shape and position of the first sub-pixel, the second sub-pixel or the third sub-pixel.

[0132] In a specific embodiment, the sub-pixel generally includes an anode layer, an emitting layer, and a cathode layer, and the emitting layer is generally deposited using the high-precision metal mask. Taking the display substrate shown in FIG. 7 as an example, in the high-precision metal mask arranged to form the first sub-pixel, as shown in FIG. 8, the opening region 01 corresponds to the shape and position of the emitting layer of the first sub-pixel 1 of the display substrate. And, due to process limitations, the area of ​​the opening region 01 is generally larger than the area of ​​the corresponding emitting layer. The principles of the high-precision metal mask arranged to form the second sub-pixel and the high-precision metal mask arranged to form the third sub-pixel are similar to those of the first sub-pixel, and will not be described in detail here.

[0133] Based on the same inventive concept, an embodiment of the present disclosure further provides a display method for any one of the above display panels, as shown in FIG. 9, the display method includes: Step 901 (S901) of receiving original image data; and step 902 (S902) of displaying, for pixels in the first display sub-region, based on the grayscale value of a pixel corresponding thereto in the original image data, and, for pixels in the second display sub-region, determining the number N of pixels corresponding to one pixel in the original image data based on the ratio between the pixel distribution density of the first display sub-region and the pixel distribution density of the second display sub-region, and displaying based on the grayscale value of one pixel or multiple pixels of the N pixels corresponding to the position of the pixel in the original image data.

[0134] In a particular embodiment, according to the above pixel distribution density formula, when the ratio of the pixel distribution density of the first display sub-region to the pixel distribution density of the second display sub-region is n, one pixel in the second display sub-region corresponds to four pixels in the original image data, i.e., N=n*n.

[0135] Optionally, in the display method according to the embodiment of the present disclosure, a pixel in the second display sub-region may be displayed based on an average grayscale value of a number of pixels among the N pixels corresponding to the pixel's position in the original image data, for example, N=4, i.e., each pixel in the second display sub-region corresponds to four pixels in the original image data, in which case each pixel in the second display sub-region may be displayed based on an average grayscale value of k pixels among the four pixels corresponding to the pixel in the original image data, where k=2, 3, or 4. Taking k=4 as an example, if the pixel in the second display sub-region includes a first sub-pixel, a second sub-pixel, and a third sub-pixel, then when displayed, the grayscale value corresponding to the first sub-pixel is X1=(x1+x2+x3+x4) / 4, where x1 to x4 respectively represent the grayscale values ​​of the first sub-pixels in the four pixels corresponding to the pixel in the second display sub-region in the original image data; similarly, when displayed, the grayscale value corresponding to the second sub-pixel is Y1=(y1+y2+y3+y4) / 4, where y1 to y4 respectively represent the grayscale values ​​of the second sub-pixels in the four pixels corresponding to the pixel in the second display sub-region in the original image data; and when displayed, the grayscale value corresponding to the third sub-pixel is Z1=(z1+z2+z3+z4) / 4, where z1 to z4 respectively represent the grayscale values ​​of the third sub-pixels in the four pixels corresponding to the pixel in the second display sub-region in the original image data.

[0136] Optionally, in a display panel according to an embodiment of the present disclosure, a pixel in the second display sub-region may be displayed based on the grayscale value of the brightest pixel among the N pixels corresponding to the position of the pixel in the original image data.

[0137] Optionally, in a display panel according to an embodiment of the present disclosure, a pixel in the second display sub-region may be displayed based on the grayscale value of the pixel having the median luminance value among N pixels corresponding to the position of the pixel in the original image data.

[0138] Optionally, in a display panel according to an embodiment of the present disclosure, a pixel in the second display sub-region may be displayed based on N pixels in the original image data that correspond to the position of the pixel, and the relative positional relationship between the pixel in the second display sub-region and the N pixels in the original image data.

[0139] Similarly, taking the case where N=4, that is, each pixel in the second display sub-region corresponds to four pixels in the original image data, if the pixels in the second display sub-region include a first sub-pixel, a second sub-pixel, and a third sub-pixel, the grayscale value X1 corresponding to the first sub-pixel when displayed is (k1*x1+k2*x2+k3*x3+k4*x4) / 4, where x1 to x4 respectively represent the grayscale values ​​of the first sub-pixels in the four pixels corresponding to the pixels in the second display sub-region in the original image data, and similarly, the grayscale value X1 corresponding to the second sub-pixel when displayed is (k1*x1+k2*x2+k3*x3+k4*x4) / 4. The grayscale value Y1 corresponding to the pixel in the second display sub-region is Y1=(k1*y1+k2*y2+k3*y3+k4*y4) / 4, where y1-y4 represent the grayscale values ​​of the second sub-pixels in the four pixels corresponding to the pixel in the second display sub-region in the original image data, and the grayscale value Z1 corresponding to the third sub-pixel when displayed is Z1=(k1*z1+k2*z2+k3*z3+k4*z4) / 4, where z1-z4 represent the grayscale values ​​of the third sub-pixels in the four pixels corresponding to the pixel in the second display sub-region in the original image data, where k1-k4 are weighting factors determined by the position of the pixel in the second display region and the spacing of each of the corresponding four pixels in the original image data, and the larger the spacing, the smaller the weighting factor.

[0140] Optionally, in the display panel according to the embodiment of the present disclosure, a pixel in the second display sub-region may be displayed based on the grayscale value of one pixel among N pixels corresponding to the pixel's position in the original image data. The display principle is based on the quantitative human visual system, does not flicker, and does not require a redesigned integrated circuit (IC), resulting in low cost.

[0141] Optionally, in the display method according to the embodiment of the present disclosure, when a ratio between a pixel distribution density of the first display sub-region and a pixel distribution density of the second display sub-region is n, where n is an integer greater than 1, Each pixel in the second display region may correspond to each of n*n pixels arranged in a matrix in the original image data.

[0142] In a specific embodiment, n=2, that is, the pixel distribution density of the first display sub-region is twice as high as that of the second display sub-region. Of course, n may have other values ​​according to practical applications and is not limited here.

[0143] Specifically, taking n=2 as an example, as shown in Figure 10, each pixel in the second display area corresponds to each of the 2 rows x 2 columns of pixels arranged in a matrix in the original image data, and in Figure 10, the four pixels within one dashed frame correspond to one pixel in the second display area.

[0144] Optionally, in a display method according to an embodiment of the present disclosure, each pixel in the second display area may use as a reference pixel one pixel located at the same position as the pixel in the original image data that corresponds to the pixel, and each pixel in the second display area may be displayed based on the grayscale value of the reference pixel that corresponds to the pixel.

[0145] Similarly, taking n=2 as an example, as shown in FIG. 11a, each pixel in the second display area uses the pixel in the first row and first column of the 2*2 pixels corresponding to the pixel in the original image data as a reference pixel. Alternatively, as shown in FIG. 11b, each pixel in the second display area uses the pixel in the first row and second column of the 2*2 pixels corresponding to the pixel in the original image data as a reference pixel. Alternatively, as shown in FIG. 11c, each pixel in the second display area uses the pixel in the second row and first column of the 2*2 pixels corresponding to the pixel in the original image data as a reference pixel. As shown in FIG. 11d, each pixel in the second display area uses the pixel in the second row and second column of the 2*2 pixels corresponding to the pixel in the original image data as a reference pixel.

[0146] In a specific embodiment, in a display method according to an embodiment of the present disclosure, each pixel in the second display area is displayed based on the grayscale value of its corresponding reference pixel, specifically, the first subpixel is displayed based on the grayscale value of the first subpixel of its corresponding reference pixel, the second subpixel is displayed based on the grayscale value of the second subpixel of its corresponding reference pixel, and the third subpixel is displayed based on the grayscale value of the third subpixel of its corresponding reference pixel.

[0147] In a particular embodiment, the ratio of the pixel distribution density of the first display sub-region to the pixel distribution density of the second display sub-region may not be an integer, for example, the ratio of the pixel distribution density of the first display sub-region to the pixel distribution density of the second display sub-region is m, where m=n+s, n is an integer equal to or greater than 1, and s is a decimal between 0 and 1. Thus, each pixel in the second display region corresponds to each of n*n pixels arranged in a matrix in the original image data, or each pixel in the second display region corresponds to each of n*(n+1) pixels arranged in a matrix in the original image data, or each pixel in the second display region corresponds to each of (n+1)*(n+1) pixels arranged in a matrix in the original image data. The implementation principle is specifically similar to the case of m=n above, and will not be described in detail here.

[0148] In the display method according to the embodiment of the present disclosure, pixels in the first display sub-region are displayed based on the grayscale value of the corresponding pixel in the original image data, and the specific implementation thereof can be referred to the related art and will not be described in detail here.

[0149] In a specific embodiment, in the display method according to the embodiment of the present disclosure, the algorithm for obtaining the grayscale value of each pixel based on the original image data can be integrated into an IC, an external central processing unit (CPU) or a microprocessor, and of course, can also be a driver installed independently and connected to each pixel, and is not limited thereto.

[0150] In a particular embodiment, in a display method according to an embodiment of the present disclosure, when a pixel on a display substrate is displayed based on its corresponding pixel in the original image data, in order to optimize the display effect, it generally needs to be processed by an image processing module such as SPR, and then processed by the Demura algorithm and displayed on a screen to form an image.

[0151] In the display substrate, the display method, the display device, and the high-precision metal mask according to the embodiments of the present disclosure, the display region is configured as a first display sub-region with a large pixel distribution density (i.e., high resolution) and a second display sub-region with a small pixel distribution density (i.e., low resolution). Since the pixel distribution density in the second display sub-region is small, elements such as a camera, a sensor, and a microphone can be installed in the second display sub-region, that is, the screen occupancy rate of the display substrate is improved by a method of improving the light transmittance of the screen by reducing the local pixel distribution density. Moreover, since the distribution of the sub-pixels in the second display sub-region is uniform, the uniformity of the luminance distribution in the second display sub-region can be ensured.

[0152] Of course, those skilled in the art can make various changes and modifications to the present disclosure without departing from the spirit and scope of the present disclosure. Therefore, if such modifications and modifications of the present disclosure fall within the scope of the claims of the present disclosure and the equivalent techniques, the present disclosure is intended to include these changes and modifications.
