Description

Technical Field

[0001] The present disclosure relates to the field of display technology, and particularly to a display substrate and a display device. Background Art

[0002] With increasing user demand for diversified display device usage and the emergence of design requirements for high screen-to-body ratios, the "under-screen camera" solution has emerged. In this solution, an imaging module, such as a camera, is embedded within the display area to reduce the size of the display's border area, thereby increasing the screen-to-body ratio. Currently, in this solution, while increasing the screen-to-body ratio of the display device, ensuring the light transmittance and display quality at the location on the display substrate corresponding to the imaging module has become a key issue for R&D personnel.

[0060] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0061] It should be noted that in the drawings, the sizes and relative sizes of elements may be exaggerated for clarity and / or descriptive purposes. Thus, the sizes and relative sizes of the individual elements are not necessarily limited to those shown in the drawings. In the specification and drawings, the same or similar reference numerals indicate the same or similar parts.

[0062] When an element is described as being "on" another element, "connected to" another element, or "bound to" another element, the element may be directly on the other element, directly connected to the other element, or directly bound to the other element, or there may be an intermediate element. However, when an element is described as being "directly on" another element, "directly connected to" another element, or "directly bound to" another element, there is no intermediate element. Other terms and / or expressions used to describe the relationship between elements should be interpreted in a similar manner, for example, "between" versus "directly between", "adjacent" versus "directly adjacent", or "on" versus "directly on", etc. In addition, the term "connected" may refer to a physical connection, an electrical connection, a communication connection, and / or a fluid connection. In addition, the X-axis, Y-axis, and Z-axis are not limited to the three axes of a rectangular coordinate system, and may be interpreted in a broader sense. For example, the X-axis, Y-axis, and Z-axis may be perpendicular to each other, or may represent different directions that are not perpendicular to each other. For the purposes of this disclosure, “at least one of X, Y, and Z” and “at least one selected from the group consisting of X, Y, and Z” may be interpreted as only X, only Y, only Z, or any combination of two or more of X, Y, and Z, such as XYZ, XYY, YZ, and ZZ. As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items.

[0063] It should be noted that although the terms "first," "second," etc. may be used herein to describe various parts, components, elements, regions, layers, and / or portions, these parts, components, elements, regions, layers, and / or portions should not be limited by these terms. Rather, these terms are used to distinguish one part, component, element, region, layer, and / or portion from another. Thus, for example, the first part, first member, first element, first region, first layer, and / or first portion discussed below may be referred to as a second part, second member, second element, second region, second layer, and / or second portion without departing from the teachings of the present disclosure.

[0064] For ease of description, spatially relative terms, such as "upper," "lower," "left," "right," etc., may be used herein to describe the relationship of one element or feature to another element or feature as shown in the figures. It should be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" or "over" the other elements or features.

[0065] As used herein, the term "repeating unit" refers to a combination of multiple sub-pixels, for example, a combination of multiple sub-pixels used to display a single pixel, with multiple "repeating units" being arranged repeatedly in an array on a substrate. For example, a repeating unit may include at least one pixel, such as two, three, four, or more sub-pixels. Furthermore, for ease of description herein, a repeating unit located in the first display area is referred to as a first repeating unit, and a repeating unit located in the second display area is referred to as a second repeating unit.

[0066] Herein, the expression "pixel density" refers to the number of repeating units or sub-pixels per unit area. Similarly, the expression "distribution density" refers to the number of components (eg, repeating units, sub-pixels, spacers, etc.) per unit area.

[0067] An embodiment of the present disclosure provides a display substrate, comprising a first display area and a second display area, wherein the display substrate comprises: a base substrate; a plurality of first repeating units arranged in an array along a first direction and a second direction on the base substrate and located in the first display area, each of the first repeating units comprising a plurality of sub-pixels; and a plurality of second repeating units arranged in an array along the first direction and the second direction on the base substrate and located in the second display area, each of the second repeating units comprising a plurality of sub-pixels. The distance between two adjacent first repeating units along the first direction is a first pitch, and the distance between two adjacent second repeating units along the first direction is a second pitch, wherein the first pitch is greater than the second pitch. Within a first repeating unit, the distance between two adjacent sub-pixels along the first direction is a first distance, and the first distance and the second pitch may have the following relationship: 0.15*second pitch≤first distance≤0.4*second pitch. Thus, in the first display area, the anode structures of the first repeating units and their corresponding light-emitting structures are concentrated and compacted, thereby reducing diffraction of light in the first display area and improving glare.

[0068] Figure 1 is a schematic plan view of a display device according to some exemplary embodiments of the present disclosure, which schematically illustrates a planar structure of a display substrate included in the display device. Figure 2 The display device according to some exemplary embodiments of the present disclosure is Figure 1 Schematic cross-sectional view taken along line AA'.

[0069] like Figure 1As shown, a display device according to an embodiment of the present disclosure includes a display substrate 10. The display substrate 10 includes display areas, which may include a first display area AA1, a second display area AA2, and a third display area AA3. For example, the first display area AA1, the second display area AA2, and the third display area AA3 do not overlap. For example, the second display area AA2 at least partially surrounds (e.g., completely surrounds) the third display area AA3, and the third display area AA3 at least partially surrounds (e.g., completely surrounds) the first display area AA1.

[0070] For a display substrate having an under-screen sensor (e.g., an image sensor), in order to improve the transmittance of the display area of the display substrate corresponding to the under-screen sensor, the unit area distribution density (PPI) of the light-emitting devices corresponding to the display area of the under-screen sensor may be smaller than the unit area distribution density of the light-emitting devices in other display areas of the display substrate.

[0071] like Figure 2 As shown, the display substrate 10 may include a base substrate 1. The sensor 2 may be provided on the back side of the base substrate 1 located at the first display area AA1 (in the Figure 2 The lower side is shown in the figure, for example, the side opposite to the light emitting direction during display), the first display area AA1 can meet the imaging requirements of the sensor 2 for light transmittance.

[0072] For example, the transmittance of the first display area AA1 is greater than the transmittance of the second display area AA2. The sensor 2 is, for example, an image sensor or an infrared sensor. The sensor 2 is configured to receive the display side ( Figure 2 The upper side of the image, for example, displays light in the direction of light, or the direction of the human eye when displaying, so that image capture, distance perception, light intensity perception and other operations can be performed. These lights, for example, pass through the first display area AA1 and illuminate the sensor, thereby being sensed by the sensor.

[0073] It should be noted that in the illustrated exemplary embodiment, the second display area AA2 completely surrounds the third display area AA3, and the third display area AA3 completely surrounds the first display area AA1. However, the embodiments of the present disclosure are not limited to this. For example, in other embodiments, the third display area AA3 may be located at the upper edge of the display substrate. For example, the third display area AA3 is surrounded on three sides by the second display area AA2, and its upper side is flush with the upper side of the display substrate. For another example, the third display area AA3 may be located at the upper edge of the display substrate and arranged along the entire width of the display substrate.

[0074] For example, the shape of the first display area AA1 can be circular or elliptical, and the shape of the second display area AA2 can be circular, elliptical, or rectangular, but the embodiments of the present disclosure are not limited thereto. For another example, the shapes of the first display area AA1 and the second display area AA2 can both be rectangular, rounded rectangular, or other suitable shapes.

[0075] exist Figures 1 to 2 In the display substrate shown, OLED display technology can be used. Due to the advantages of OLED display substrates such as wide viewing angle, high contrast, fast response, low power consumption, foldability, and flexibility, they are increasingly widely used in display products. With the development and in-depth application of OLED display technology, the demand for high screen-to-body ratio displays is becoming increasingly strong. Figures 1 to 2 The display substrate shown uses an under-screen camera solution. This eliminates the notch area, avoids digging a hole in the display, and increases the screen-to-body ratio for a better visual experience.

[0076] In addition, the display substrate may further include a driving circuit layer, a light emitting device layer and a packaging layer provided on the base substrate 1. For example, Figure 2 The figure schematically illustrates a drive circuit layer 3, a light-emitting device layer 4, and an encapsulation layer 5. The drive circuit layer 3 includes a drive circuit structure, and the light-emitting device layer 4 includes light-emitting devices, such as OLEDs. The drive circuit structure controls the light-emitting devices in each sub-pixel to achieve the display function. The drive circuit structure includes thin-film transistors, storage capacitors, and various signal lines. These various signal lines include gate lines, data lines, ELVDD power lines, and ELVSS power lines, etc., to provide various signals such as control signals, data signals, and power supply voltage to the pixel drive circuit in each sub-pixel.

[0077] Figure 3 for Figure 1 The figure shows a partial schematic diagram of the first display area, the second display area and the third display area of the display substrate. Figure 4 for Figure 3 An enlarged view of a portion of the REG1 region, Figure 5 for Figure 3 An enlarged view of a portion of the REG2 region.

[0078] Reference Figures 3 to 5The first display area AA1 includes a plurality of first repeating units P1 arranged in an array, and the second display area AA2 includes a plurality of second repeating units P2 arranged in an array. Each repeating unit P1 and P2 may include multiple sub-pixels. In some embodiments, the first repeating unit P1 may further include multiple sub-pixels, such as red sub-pixels, green sub-pixels, and blue sub-pixels; similarly, the second repeating unit P2 may further include multiple sub-pixels, such as red sub-pixels, green sub-pixels, and blue sub-pixels.

[0079] It should be noted that the embodiments of the present disclosure are described using red, green and blue as examples, but the embodiments of the present disclosure are not limited thereto. That is, each repeating unit may include at least two sub-pixels of different colors, such as a first color sub-pixel, a second color sub-pixel and a third color sub-pixel, and the first color, the second color and the third color are different colors from each other.

[0080] For example, in some exemplary embodiments of the present disclosure, a first repeating unit P1 includes at least one (eg, Figure 4 In the example, two) first color sub-pixels, at least one (for example, Figure 4 In the example, two) second color sub-pixels and at least one (for example, Figure 4 For the convenience of description, the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel included in the first repeating unit P1 are respectively referred to as the first sub-pixel, the second sub-pixel, and the third sub-pixel, and are respectively represented by reference numerals SP1, SP2, and SP3. A second repeating unit P2 includes at least one (for example, Figure 5 In the example, one) first color sub-pixel, at least one (for example, Figure 5 exemplified as one) second color sub-pixel and at least one (eg, Figure 5In the example, two are shown) as the third color sub-pixel. For ease of description, the first color sub-pixel, the second color sub-pixel and the third color sub-pixel included in the second repeating unit P2 are referred to as the fourth sub-pixel, the fifth sub-pixel and the sixth sub-pixel, respectively, and are represented by reference numerals SP4, SP5 and SP6, respectively. For example, the first color can be red, the second color can be blue, and the third color can be green. Among them, a sub-pixel may include a light-emitting device and a pixel driving circuit for driving the light-emitting device to emit light, the light-emitting device may include a first electrode, a second electrode and a light-emitting material layer located therein, the pixel driving circuit may include components such as transistors and capacitors, the pixel driving circuit receives a signal from a signal line provided on the display substrate, generates a current driving the light-emitting device, and achieves the purpose of driving the light-emitting device to emit light by being connected to one of the first electrode or the second electrode. For example, the pixel driving circuit is provided on the base substrate, and the light-emitting device is located on the side of the pixel driving circuit away from the base substrate. In some embodiments, the display substrate further includes a pixel defining layer located on the side of the first electrode away from the pixel driving circuit, the pixel defining layer includes a plurality of openings, each sub-pixel corresponds to at least one pixel defining layer opening (e.g., one), and the actual light-emitting area or display area of the sub-pixel is roughly equivalent to the pixel defining layer opening corresponding to the sub-pixel. In some embodiments, the pixel definition layer opening or actual light emitting area corresponding to each sub-pixel is smaller than the area of the first electrode, and the projection on the substrate completely falls within the projection of the first electrode on the substrate. Figure 4 and Figure 5 In the figures, only the approximate position and shape of the first electrodes (eg, anode structures) of the sub-pixels are shown to illustrate the distribution of the sub-pixels.

[0081] For example, in some embodiments of the present disclosure, the arrangement of sub-pixels in each repeating unit may refer to conventional pixel arrangements, such as GGRB, RGBG, RGB, etc., and the embodiments of the present disclosure are not limited thereto.

[0082] like Figure 3 As shown, the first display area AA1 has a first pixel density, and the second display area AA2 has a second pixel density that is not less than the first pixel density, for example, the second pixel density is greater than the first pixel density. In the first display area AA1, the blank areas between the multiple first repeating units P1 allow more light to pass through, thereby improving the light transmittance of this area. Therefore, compared to the second display area AA2, the first display area AA1 has a higher light transmittance.

[0083] It should be noted that, in this article, the blank area between the plurality of first repeating units P1 may be referred to as a light-transmitting area TRA.

[0084] like Figure 5As shown, each sub-pixel located in the second display area AA2 may include a second light-emitting device 42. For example, the second light-emitting device 42 may include an anode structure, a light-emitting material layer, and a cathode structure that are stacked. It should be noted that, for the sake of clarity, the relevant drawings use the anode structure of the second light-emitting device 42 to schematically illustrate the second light-emitting device 42, thereby schematically representing the sub-pixels located in the second display area AA2. For example, in the second display area AA2, the anode structure of the second light-emitting device 42 includes an anode body 421 and an anode connecting portion 422. The orthographic projection of the anode body 421 on the base substrate 1 may have a regular shape, such as a hexagon. A pixel driving circuit (to be described below) for driving the second light-emitting device 42 is also provided in the second display area AA2, and the anode connecting portion 422 is electrically connected to the pixel driving circuit of the second light-emitting device 42.

[0085] For example, in Figure 5 In the embodiment of the present invention, in the second display area AA2, the orthographic projection of the anode body 421 of each of the fourth and fifth sub-pixels on the base substrate 1 may be a regular hexagonal shape (e.g., a rounded hexagonal shape), and the orthographic projection of the anode body 421 of the sixth sub-pixel on the base substrate 1 may be a regular pentagonal shape (e.g., a rounded pentagonal shape). It should be noted that the shape of the orthographic projection of the anode body 421 on the base substrate 1 is not limited to the above shapes and may be any suitable shape, such as an octagon, a rectangle, a rounded rectangle, etc.

[0086] like Figure 4 As shown, each sub-pixel located in the first display area AA1 may include a first light emitting device 41. For example, the first light emitting device 41 may include a stacked anode structure, a light emitting material layer, and a cathode structure. Figure 4 In the figure, the anode structure of the first light-emitting device 41 is used to schematically illustrate the first light-emitting device 41, thereby schematically representing a sub-pixel. For example, the first display area AA1 includes a plurality of first light-emitting devices 41 arranged in an array, and the first light-emitting devices 41 are configured to emit light. For example, there is no pixel driving circuit in the first display area AA1, and the pixel driving circuit for driving the first light-emitting device 41 is provided in the third display area AA3, thereby reducing the metal coverage area of the first display area AA1 and increasing the transmittance of the first display area AA1, thereby making the transmittance of the first display area AA1 greater than the transmittance of the second display area AA2.

[0087] For example, in Figure 4In the embodiment, in the first display area AA1, the orthographic projection of the anode structure of each of the first sub-pixel, the second sub-pixel, and the third sub-pixel on the base substrate 1 may be substantially circular or elliptical. This increases the light-emitting area of the light-emitting device of each sub-pixel in the first display area AA1, thereby improving the service life of the light-emitting device of each sub-pixel in the first display area AA1.

[0088] It should be understood that the anode structure of the first light-emitting device 41 may include an anode body and an anode connection portion. The orthographic projection of the anode body on the base substrate 1 may be substantially circular or elliptical. The anode connection portion of the first light-emitting device 41 may be electrically connected to the first end of the first connection line 110 (described below), thereby electrically connecting the first light-emitting device 41 to its pixel driving circuit.

[0089] like Figures 3 to 5 As shown, a plurality of first repeating units P1 and a plurality of second repeating units P2 are arranged in an array on the base substrate 1 of the display substrate 10. For example, a plurality of first repeating units P1 are arranged in an array along a first direction (the X direction shown in the figure) and a second direction (the Y direction shown in the figure) in the first display area AA1. A plurality of second repeating units P2 are arranged in an array along the first direction (the X direction shown in the figure) and a second direction (the Y direction shown in the figure) in the second display area AA2.

[0090] The distance between adjacent first repeating units P1 in the first direction X can be referred to as the pitch of the first repeating units P1 or the pitch in the first display area AA1, as shown in the figure, and is represented by the reference symbol PT1. For example, the pitch of the first repeating unit P1 or the pitch in the first display area AA1 is the distance along the first direction X between the centers of two first color sub-pixels located in the same row of two adjacent first repeating units P1, or the distance between the centers of two second color sub-pixels located in the same row of two adjacent first repeating units P1. The distance between adjacent second repeating units P2 in the first direction X can be referred to as the pitch of the second repeating unit P2 or the pitch in the second display area AA2, as shown in the figure, and is represented by the reference symbol PT2. For example, the pitch of the second repeating unit P2 or the pitch in the second display area AA2 is the distance between the centers of the two most adjacent first color sub-pixels in the first direction X, or the distance between the centers of the two most adjacent second color sub-pixels in the first direction X.

[0091] For example, refer to Figure 4The first repeating unit P1 may include a plurality of sub-pixels arranged in four rows and four columns. In the first row, the first sub-pixel SP1 and the second sub-pixel SP2 are arranged in the first and third columns, respectively. In the second row, the two third sub-pixels SP3 are arranged in the second and fourth columns, respectively. In the third row, the second sub-pixel SP2 and the first sub-pixel SP1 are arranged in the first and third columns, respectively. In the fourth row, the two third sub-pixels SP3 are arranged in the second and fourth columns, respectively.

[0092] It should be noted that, in the embodiments of the present disclosure, the first direction X may be referred to as a row direction, and the second direction Y may be referred to as a column direction.

[0093] Figure 8 for Figure 3 FIG. 1 is an enlarged view of a partial region REG1 in FIG. 2 , showing the distance between sub-pixels in the first repeating unit and the pitch between the first repeating units.

[0094] For example, Figure 8 As shown in FIG, the distance between two sub-pixels of the same color located in two adjacent first repeating units P1 and in the same row along the first direction X can represent the first pitch PT1. Figure 8 In the embodiment of the present invention, the “two sub-pixels of the same color” herein may include “two sub-pixels of the first color” or “two sub-pixels of the second color”. In addition, due to Figure 8 In the embodiment, four sub-pixels of the third color are arranged in two adjacent first repeating units P1 and in the same row, so the “two sub-pixels of the same color” here does not include the case of “two sub-pixels of the third color”.

[0095] For example, Figure 5 As shown, the distance along the first direction X between two sub-pixels of the same color located in two adjacent second repeating units P2 can represent the second pitch PT2.

[0096] In some embodiments of the present disclosure, the first pitch PT1 is greater than the second pitch PT2. That is, the spacing between the first repeating units P1 increases. As a result, the distribution density of the first repeating units P1 in the first display area AA1 is less than the distribution density of the second repeating units P2 in the second display area AA2.

[0097] In a first repeating unit P1, the distance between two adjacent sub-pixels in the same row may be referred to as a first distance, which may be represented by reference symbol PD1. Figure 8 As shown, in the first repetition unit P1 on the upper left side, the distance between the first sub-pixel SP1 and the second sub-pixel SP2 in the first row can represent the first distance PD1.

[0098] In a first repeating unit P1, the distance between two adjacent sub-pixels in the same column may be referred to as a second distance, which may be represented by reference symbol PD2. Figure 8 As shown, in the first repetition unit P1 on the upper left side, the distance between the first sub-pixel SP1 and the second sub-pixel SP2 in the first column can represent the second distance PD2.

[0099] For example, the first distance PD1 can be substantially equal to the second distance PD2. In some embodiments, the first distance PD1 and the second pitch PT2 can be in the following relationship: 0.3*PT2≤PD1≤0.8*PT2. For example, PD1 can be substantially equal to 0.65*PT2. In this manner, within the first repeating unit P1, the sub-pixels are clustered and compacted.

[0100] For example, in some embodiments, the second pitch PT2 may be substantially equal to about 102 microns, and the first distance PD1 may be in the range of 30.6 to 81.6 microns, eg, about 70-80 microns, such as about 78 microns.

[0101] In two first repeating units P1 adjacent to each other along the first direction X, the distance between two sub-pixels respectively located in the two first repeating units P1 and adjacent to each other in the first direction X can be referred to as a first spacing, which can be represented by reference symbol PS1. Figure 8 As shown, in two adjacent first repeating units P1 along the first direction X, the distance between the second subpixel SP2 in the first column of one first repeating unit P1 and the first subpixel SP1 in the first column of the other first repeating unit P1 can represent the first spacing PS1.

[0102] In two first repeating units P1 adjacent to each other along the second direction Y, the distance between two sub-pixels located in the two first repeating units P1 and adjacent to each other in the second direction Y can be referred to as a second spacing, which can be represented by reference symbol PS2. Figure 8 As shown, in two adjacent first repeating units P1 along the second direction Y, the distance between the second subpixel SP2 in the first column of one first repeating unit P1 and the first subpixel SP1 in the first column of the other first repeating unit P1 can represent the second spacing PS2.

[0103] For example, the first pitch PS1 can be substantially equal to the second pitch PS2. In some embodiments, the first pitch PS1 and the second pitch PT2 can be in the following relationship: 1.2*PT2≤PS1≤1.7*PT2. For example, PS1 can be substantially equal to 1.35*PT2. In this way, the distance between each first repeating unit P1 in the first display area AA1 is increased.

[0104] For example, in some embodiments, the first pitch PS1 can be in the range of 1228-175 microns, eg, approximately 155-165 microns, such as approximately 162 microns.

[0105] It should be noted that, in the embodiments of the present disclosure, the distance between sub-pixels can be represented by the distance between the centers of the openings of the pixel defining layers corresponding to the sub-pixels, or by the distance between the centers of the anode structures of the sub-pixels. Figure 4 and Figure 8 In the illustrated embodiment, each circle may represent the orthographic projection of the anode structure of each sub-pixel on the substrate. The center of each sub-pixel may be the center of the circle, and the distance between sub-pixels may be represented by the distance between the centers of the sub-pixels.

[0106] Figure 6 and Figure 7 According to some embodiments of the present disclosure Figure 3 An enlarged view of a portion of the REG1 region.

[0107] For example, in Figure 6 In the embodiment, in the first display area AA1, the orthographic projection of the anode structure of each of the first sub-pixel, the second sub-pixel, and the third sub-pixel on the base substrate 1 may be elliptical. In this way, the light-emitting area of the light-emitting device of each sub-pixel in the first display area AA1 can be increased, thereby improving the service life of the light-emitting device of each sub-pixel in the first display area AA1.

[0108] Reference Figure 6 , the major axis of the (elliptical) anode structure of each of the first sub-pixel, the second sub-pixel and the third sub-pixel extends substantially along the second direction Y.

[0109] The first repeating unit P1 may include a plurality of sub-pixels arranged in four rows and four columns. In the first row, the first sub-pixel SP1 and the third sub-pixel SP3 are arranged in the first and second columns, respectively. In the second row, the third sub-pixel SP3 and the second sub-pixel SP2 are arranged in the third and fourth columns, respectively. In the third row, the third sub-pixel SP3 and the second sub-pixel SP2 are arranged in the first and second columns, respectively. In the fourth row, the first sub-pixel SP1 and the third sub-pixel SP3 are arranged in the third and fourth columns, respectively.

[0110] Through such an arrangement, the sub-pixels in the first repeating unit P1 can be arranged closely, thereby achieving the purpose of clustering and compacting the sub-pixels in the first repeating unit P1.

[0111] Similarly, in this embodiment, the first distance PD1 can be substantially equal to the second distance PD2. In some embodiments, the first distance PD1 and the second pitch PT2 can be in the following relationship: 0.3*PT2≤PD1≤0.8*PT2. For example, PD1 can be substantially equal to 0.65*PT2. In this manner, the sub-pixels within the first repeating unit P1 are clustered and compacted.

[0112] The first pitch PS1 can be substantially equal to the second pitch PS2. In some embodiments, the first pitch PS1 and the second pitch PT2 can be in the following relationship: 1.2*PT2≤PS1≤1.7*PT2. For example, PS1 can be substantially equal to 1.35*PT2. In this way, the distance between each first repeating unit P1 in the first display area AA1 is increased.

[0113] For example, in Figure 7 In the embodiment, in the first display area AA1, the orthographic projection of the anode structure of the first sub-pixel on the base substrate 1 can be circular, and the orthographic projection of the anode structure of each of the second sub-pixel and the third sub-pixel on the base substrate 1 can be elliptical. In this way, the light-emitting area of the light-emitting device of each sub-pixel in the first display area AA1 can be increased, thereby improving the service life of the light-emitting device of each sub-pixel in the first display area AA1.

[0114] The major axis of the (elliptical) anode structure of each of the second and third sub-pixels extends substantially along the second direction Y.

[0115] The first repeating unit P1 may include a plurality of sub-pixels arranged in four rows and four columns. In the first row, the first sub-pixel SP1 and the second sub-pixel SP2 are arranged in the first and third columns, respectively. In the second row, the two third sub-pixels SP3 are arranged in the second and fourth columns, respectively. In the third row, the second sub-pixel SP2 and the first sub-pixel SP1 are arranged in the first and third columns, respectively. In the fourth row, the two third sub-pixels SP3 are arranged in the second and fourth columns, respectively.

[0116] Through such an arrangement, the sub-pixels in the first repeating unit P1 can be arranged closely, thereby achieving the purpose of clustering and compacting the sub-pixels in the first repeating unit P1.

[0117] Similarly, in this embodiment, the first distance PD1 can be substantially equal to the second distance PD2. In some embodiments, the first distance PD1 and the second pitch PT2 can be in the following relationship: 0.3*PT2≤PD1≤0.8*PT2. For example, PD1 can be substantially equal to 0.65*PT2. In this manner, the sub-pixels within the first repeating unit P1 are clustered and compacted.

[0118] The first pitch PS1 can be substantially equal to the second pitch PS2. In some embodiments, the first pitch PS1 and the second pitch PT2 can be in the following relationship: 1.2*PT2≤PS1≤1.7*PT2. For example, PS1 can be substantially equal to 1.35*PT2. In this way, the distance between each first repeating unit P1 in the first display area AA1 is increased.

[0119] It should be noted that, in the embodiments of the present disclosure, the distance between sub-pixels can be represented by the distance between the centers of the openings of the pixel defining layers corresponding to the sub-pixels, or by the distance between the centers of the anode structures of the sub-pixels. Figure 6 and Figure 7 In the illustrated embodiment, each circle or ellipse may represent the orthographic projection of the anode structure of each sub-pixel on the substrate. The center of each sub-pixel is the center of the circle or the center of the ellipse, and the distance between sub-pixels may be represented by the distance between the centers of the circles or ellipses of the sub-pixels.

[0120] In the embodiment of the present disclosure, in the first display area AA1, the orthographic projection of the anode structure of each of the first sub-pixel, the second sub-pixel, and the third sub-pixel on the base substrate 1 may be circular or elliptical. Figure 4 、 Figure 6 and Figure 7 Only a few examples are shown, and the embodiments of the present disclosure are not limited to these examples. The embodiments of the present disclosure may also adopt other combinations of circular and elliptical shapes. For example, in some embodiments, the second sub-pixel SP2 may be circular, and the first sub-pixel SP1 and the third sub-pixel SP3 may be elliptical; in some embodiments, the third sub-pixel SP3 may be circular, and the first sub-pixel SP1 and the second sub-pixel SP2 may be elliptical; in some embodiments, the first sub-pixel SP1 may be elliptical, and the second sub-pixel SP2 and the third sub-pixel SP3 may be circular; in some embodiments, the second sub-pixel SP2 may be elliptical, and the first sub-pixel SP1 and the third sub-pixel SP3 may be circular; in some embodiments, the third sub-pixel SP3 may be elliptical, and the first sub-pixel SP1 and the second sub-pixel SP2 may be circular.

[0121] In addition, Figure 6 and Figure 7 In the embodiment of the present disclosure, the major axis of the ellipse extends along the second direction Y, but the embodiments of the present disclosure are not limited thereto. In some embodiments, the major axis of the ellipse may extend along the first direction X.

[0122] Figure 9 yes Figure 3FIG. 1 is an enlarged view of a partial region REG3 in FIG. 1 , which schematically shows the transition region between the first repeating unit and the second repeating unit. Figure 9 As shown, along the first direction X, a gap REG4 exists between the boundary of the first repeating unit P1 in the first display area AA1 and the boundary of the second repeating unit P2 in the second display area AA2. Along the second direction Y, a gap REG5 exists between the boundary of the first repeating unit P1 in the first display area AA1 and the boundary of the second repeating unit P2 in the second display area AA2. It should be understood that the sizes of gaps REG4 and REG5 can be determined based on factors such as the size of the sensor 2 to be set and the size of the first repeating unit P1.

[0123] In the embodiments of the present disclosure, in the first display area AA1, the anode structures of the first repeating units and their corresponding light-emitting structures are clustered and compacted. Accordingly, the spacing between the first repeating units is increased, which can reduce light diffraction in the first display area and improve glare. Furthermore, elliptical or circular shapes of the anode structures of the first repeating units and their corresponding light-emitting structures can also reduce light diffraction in the first display area and improve glare.

[0124] Figure 10 for Figure 3 FIG1 is an enlarged view of a partial region REG1′ in FIG1 , which schematically shows wires for electrically connecting each sub-pixel in the first display area AA1 to its pixel driving circuit. Figure 11 for Figure 3 An enlarged view of a part of the REG3 region, Figure 11 The enlarged view of the area only includes one column of first pixel driving circuits, one column of first light emitting devices, one column of second pixel driving circuits and one column of second light emitting devices. It should be noted that in order to clearly show the connection between the first pixel driving circuit and the first light emitting device, Figure 11 The adjacent first pixel driving circuit and the first light emitting device are shown to be connected to each other, but according to Figure 3 、 Figure 10 and Figure 11 , I can understand, Figure 11 Other first light-emitting devices, not shown, may be further provided on the left side of the first light-emitting device in the figure, and other first pixel driving circuits, not shown, may be further provided on the right side of the first pixel driving circuit.

[0125] It should be noted that, in this article, for the convenience of description, the light-emitting device located in the first display area AA1 is referred to as the first light-emitting device, and accordingly, the circuit used to drive it to emit light is called the first pixel driving circuit; the light-emitting device located in the second display area AA2 is referred to as the second light-emitting device, and accordingly, the circuit used to drive it to emit light is called the second pixel driving circuit.

[0126] For example, Figure 11 As shown, the third display area AA3 includes at least one (e.g., multiple) first pixel driving circuits 412. For example, the first light-emitting devices 41 are electrically connected to the first pixel driving circuits 412 in a one-to-one correspondence, and the multiple first pixel driving circuits 412 are used to drive the multiple first light-emitting devices 41 in a one-to-one correspondence. Figure 11 The rectangular box shown (the black-bordered, white-filled area indicated by reference numeral 412) represents a first pixel driving circuit 412. For example, the first pixel driving circuit 412 is configured to drive a plurality of first light-emitting devices 41 to emit light in a one-to-one correspondence. That is, one first pixel driving circuit 412 drives one corresponding first light-emitting device 41, and different first pixel driving circuits 412 drive different first light-emitting devices 41.

[0127] In the embodiment of the present disclosure, the pixel driver circuit for driving each sub-pixel in the first display area AA1 is not located in the first display area AA1, but is instead provided in the third display area AA3. For example, the anode structure of the first light-emitting device 41 is electrically connected to the first end of the first connection line 110 via a via. The orthographic projection of the first light-emitting device 41 on the substrate 1 is spaced apart from the orthographic projection of the first pixel driver circuit 412 on the substrate 1. This reduces the coverage area of the metal or opaque pattern in the first display area AA1, improving the light transmittance of the first display area AA1 and thereby making the light transmittance of the first display area AA1 greater than that of the second display area AA2.

[0128] For example, Figure 11 As shown, the display substrate further includes a plurality of first connection lines 110 provided on the base substrate 1. The first connection lines 110 include a first end located in the first display area 11 and a second end located in the third display area AA3, that is, the first connection lines 110 extend from the first display area 11 to the third display area AA3.

[0129] The first end of the first connecting line 110 is electrically connected to the anode structure of the first light-emitting device 41 of a sub-pixel, and the second end of the first connecting line 110 is electrically connected to the first pixel driving circuit 412. The first connecting line 110 is configured to transmit the electrical signal provided by the first pixel driving circuit 412 to the anode structure of the first light-emitting device 41, thereby driving the first light-emitting device 41 to emit light.

[0130] like Figure 11 As shown, the second display area AA2 further includes at least one (e.g., multiple) second light-emitting devices 42 and at least one (e.g., multiple) second pixel driving circuits 424. The second light-emitting devices 42 are electrically connected to the second pixel driving circuits 424 in a one-to-one correspondence, and the second pixel driving circuits 424 are used to drive the second light-emitting devices 42 to emit light.

[0131] It should be noted that in Figure 11 In the figure, the rectangular frames indicated by reference numerals 412 and 424 are only used to illustrate the approximate positions of the first pixel driving circuit 412 and the second pixel driving circuit 424, but do not indicate their specific shapes and their specific boundaries.

[0132] In the embodiment of the present disclosure, the pixel driving circuit for driving each sub-pixel in the second display area AA2 is located in the second display area AA2. For example, the orthographic projection of the second light-emitting device 42 on the base substrate 1 at least partially overlaps with the orthographic projection of the second pixel driving circuit 424 on the base substrate 1. This facilitates electrical connection between each light-emitting device 42 located in the second display area AA2 and the corresponding second pixel driving circuit 424.

[0133] Figure 12 for Figure 11 Schematic diagram of the cross section along line BB'. Figure 12 The display substrate 10 includes a pixel driving circuit structure layer sequentially stacked on the base substrate 1, wherein the pixel driving circuit structure layer may include a thin film transistor T, an insulating layer 31, a first connecting line 110, a planarization layer 32, and a first light-emitting device 41. The first light-emitting device 41 includes an anode structure 41A, a cathode structure 41C, and a light-emitting structure 41B located between the anode structure 41A and the cathode structure 41C. The anode structure 41A of the first light-emitting device 41 is electrically connected to the first connecting line 110 via a first via VH1 penetrating the planarization layer 32. The pixel driving circuit structure layer may include a semiconductor layer, a first insulating layer, a first gate layer, a second insulating layer, a second gate layer, an interlayer insulating layer, a source / drain metal layer, etc. In some embodiments, the pixel driving circuit may include seven thin film transistors (e.g., a driving transistor, a data writing transistor, a compensation transistor, a reset transistor, a light-emitting control transistor, etc.), and a storage capacitor, wherein at least one thin film transistor is directly connected to the light-emitting device, such as the light-emitting control transistor. Figure 12 A thin film transistor T (for example, a light emitting control transistor) is schematically shown. The thin film transistor T includes at least an active layer located in a semiconductor layer, a source contact portion, a drain contact portion, a gate located in a first gate layer, and a source and a drain located in a source-drain metal layer. Figure 12 The first connection line 110 in the embodiment is, for example, electrically connected to the drain of the light emitting control transistor located in the source-drain metal layer.

[0134] It should be noted that, in this document, unless otherwise specified, "vias" are used to electrically connect components located in different conductive layers. In the embodiments of the present disclosure, "vias" can also take other alternative forms. For example, "grooves" that can be used to electrically connect components located in different conductive layers can replace the vias.

[0135] For example, the anode structure 41A may include a transparent conductive material such as ITO. The embodiments of the present disclosure do not limit the specific material of the anode structure 41A. For example, the cathode structure 41C may be formed on the entire surface of the display substrate 10 (e.g., at least completely covering the entire display area). The cathode structure 41C may include, for example, a metal material such as lithium (Li), aluminum (Al), magnesium (Mg), or silver (Ag). For example, because the cathode structure 41C can be formed as a very thin layer, the cathode structure 41C has good light transmittance.

[0136] Combined with reference Figure 10 and Figure 12 The orthographic projection of the anode structure 41A on the base substrate 1 is circular and covers the orthographic projection of the via hole VH1 on the base substrate 1 .

[0137] Reference Figure 10 In the first display area AA1, a plurality of first connection lines 110 are provided. For example, each first connection line 110 extends along the first direction X. At least some of the plurality of first connection lines 110 are dummy lines. Figure 10 Some connecting wires are shown as being disconnected, and these connecting wires are not electrically connected to any light emitting device.

[0138] For example, the first connection line 110 may include a transparent conductive material such as ITO, so that the first connection line 110 has good light transmittance.

[0139] Figure 13 for Figure 11 Schematic cross-section along line CC'. Figure 14 Schematic diagram schematically showing the anode structure of a sub-pixel located in the first display area and the planar structure of the pixel opening. Figure 15 Schematic diagram schematically showing the anode structure of a sub-pixel located in the second display area and the planar structure of the pixel opening.

[0140] Combined with reference Figures 11 to 15The display substrate 10 may further include a pixel defining layer 8. For example, the pixel defining layer 8 may have a plurality of first openings 82 and a plurality of second openings 84. The plurality of first openings 82 are located in the first display area AA1, and each first opening 82 exposes a portion of the anode structure of the first light-emitting device 41. The plurality of second openings 84 are located in the second display area AA2, and each second opening 84 exposes a portion of the anode structure of the second light-emitting device 42, for example, exposing at least a portion of the anode body 421 of the second light-emitting device 42.

[0141] In the embodiment of the present disclosure, a portion of the light-emitting structure 41B is filled in the first opening 82 to contact the exposed portion of the anode structure 41A. The actual light-emitting area of each sub-pixel is determined by the area of the portion of the light-emitting structure 41B that contacts the anode structure 41A, that is, by the area of each opening 82 in the pixel-defining layer 8.

[0142] In the embodiment of the present disclosure, the orthographic projection of the first opening 82 on the base substrate 1 may be circular or elliptical, so as to increase the light emitting area of each sub-pixel and thus improve the service life of the light emitting device in the first display area AA1.

[0143] Reference Figure 14 The orthographic projection of the first opening 82 on the base substrate 1 falls within the orthographic projection of the anode structure of the first light-emitting device 41 on the base substrate 1, and the area of the orthographic projection of the first opening 82 on the base substrate 1 is smaller than the area of the orthographic projection of the anode structure of the first light-emitting device 41 on the base substrate 1.

[0144] As described above, the orthographic projection of the anode structure of the first light-emitting device 41 on the base substrate 1 may be substantially circular or elliptical. In the first display area AA1, the pixel defining layer 8 includes a first protrusion 85, the orthographic projection of which on the base substrate 1 covers the orthographic projection of the first via hole or first groove VH1 on the base substrate 1.

[0145] It should be noted that, since the pixel defining layer 8 needs to cover the first via hole or the first groove VH1, the first opening 82 of the pixel defining layer 8 does not expose the first via hole or the first groove VH1. In this way, the pixel defining layer 8 protrudes toward the first opening 82 at a position directly above the first via hole or the first groove VH1, thereby forming the first protrusion 85.

[0146] like Figure 14As shown, the orthographic projection of the combination of the first protrusion 85 and the first opening 82 on the substrate 1 is circular or elliptical, and the orthographic projection of the combination of the first protrusion 85 and the first opening 82 on the substrate 1 falls within the orthographic projection of the anode structure of the first light-emitting device 41 on the substrate 1. The orthographic projection of the combination of the first protrusion 85 and the first opening 82 on the substrate 1 and the orthographic projection of the anode structure of the first light-emitting device 41 on the substrate 1 have the same center. For example, if the orthographic projection of the anode structure of the first light-emitting device 41 on the substrate 1 is substantially circular, the orthographic projection of the combination of the first protrusion 85 and the first opening 82 on the substrate 1 also forms a substantially circular shape, and the two circles are concentric circles, and the radius of the orthographic projection of the anode structure of the first light-emitting device 41 on the substrate 1 is greater than the radius of the orthographic projection of the combination of the first protrusion 85 and the first opening 82 on the substrate 1.

[0147] In an embodiment of the present disclosure, the anode structure of the first light emitting device 41 includes a central portion 416 and a peripheral portion 417 surrounding the central portion. The thickness of at least a portion of the peripheral portion 417 is different from that of the central portion 416 .

[0148] It should be noted that, in this article, the central part of the anode structure may include a part of the anode structure with the center of the anode structure as the center and 1 / 4 of the radius of the anode structure as the radius. For example, when the orthographic projection of the anode structure of the first light-emitting device 41 on the substrate 1 is approximately circular, the orthographic projection of the central part of the anode structure on the substrate 1 is also approximately circular, and the two circles are concentric circles, and the radius of the orthographic projection of the central part of the anode structure on the substrate 1 is approximately 1 / 4 of the radius of the orthographic projection of the anode structure of the first light-emitting device 41 on the substrate 1.

[0149] The peripheral portion 417 may include a first portion, the orthographic projection of which on the base substrate 1 covers the orthographic projection of the first via hole or first groove VH1 on the base substrate 1. In other words, the first portion is the portion of the anode structure of the first light-emitting device 41 within the first via hole or first groove VH1. Because the anode structure of the first light-emitting device 41 is connected to the underlying conductive layer at the first via hole or first groove VH1, the thickness of the first portion of the peripheral portion 417 is greater than the thickness of the central portion 416.

[0150] Similarly, the anode structure of the second light emitting device 42 includes an anode body 421 and an anode connecting portion 422 , and at least a portion of the anode connecting portion 422 has a thickness different from that of the anode body 421 .

[0151] Since the anode connection portion 422 of the second light emitting device 42 is connected to the source or drain of the thin film transistor below at the via hole VH3 (described in more detail below), the thickness of at least a portion of the anode connection portion 422 is greater than the thickness of the anode body 421.

[0152] In the embodiment of the present disclosure, the anode structure of the first light-emitting device 41 is connected to the underlying conductive layer, which is then connected to the source or drain of the underlying thin-film transistor. The anode connection portion 422 of the second light-emitting device 42 is connected to the source or drain of the underlying thin-film transistor. Thus, the thickness of the first portion of the anode structure of the first light-emitting device 41 is less than the thickness of the anode connection portion 422 of the anode structure of the second light-emitting device 42.

[0153] In an embodiment of the present disclosure, the area of the orthographic projection of the anode structure in a sub-pixel in the first repeating unit P1 on the substrate 1 is larger than the area of the orthographic projection of the anode structure in a sub-pixel of the same color in the second repeating unit P2 on the substrate 1. For example, the area of the orthographic projection of the anode structure in a red sub-pixel in the first repeating unit P1 on the substrate 1 is larger than the area of the orthographic projection of the anode structure in a red sub-pixel in the second repeating unit P2 on the substrate 1. For another example, the area of the orthographic projection of the anode structure in a blue sub-pixel in the first repeating unit P1 on the substrate 1 is larger than the area of the orthographic projection of the anode structure in a blue sub-pixel in the second repeating unit P2 on the substrate 1. For another example, the area of the orthographic projection of the anode structure in a green sub-pixel in the first repeating unit P1 on the substrate 1 is larger than the area of the orthographic projection of the anode structure in a green sub-pixel in the second repeating unit P2 on the substrate 1.

[0154] In an embodiment of the present disclosure, the orthographic projection area of a first opening 82 in a sub-pixel in the first repeating unit P1 on the substrate 1 is larger than the orthographic projection area of a second opening 84 in a sub-pixel of the same color in the second repeating unit P2 on the substrate 1. For example, the orthographic projection area of the first opening 82 in the red sub-pixel in the first repeating unit P1 on the substrate 1 is larger than the orthographic projection area of the second opening 84 in the red sub-pixel in the second repeating unit P2 on the substrate 1. For another example, the orthographic projection area of the first opening 82 in the green sub-pixel in the first repeating unit P1 on the substrate 1 is larger than the orthographic projection area of the second opening 84 in the green sub-pixel in the second repeating unit P2 on the substrate 1. For another example, the orthographic projection area of the first opening 82 in the blue sub-pixel in the first repeating unit P1 on the substrate 1 is larger than the orthographic projection area of the second opening 84 in the blue sub-pixel in the second repeating unit P2 on the substrate 1.

[0155] In some embodiments, the orthographic projection of the first opening 82 in a sub-pixel in the first repeating unit P1 onto the substrate 1 along the second direction Y is greater than the orthographic projection of the second opening 84 in a sub-pixel of the same color in the second repeating unit P2 onto the substrate along the second direction. For example, the orthographic projection of the first opening 82 in the red sub-pixel in the first repeating unit P1 onto the substrate 1 along the second direction Y is greater than the orthographic projection of the second opening 84 in the red sub-pixel in the second repeating unit P2 onto the substrate along the second direction. Similarly, the blue and green sub-pixels can be configured in the same manner, and no further details are given here.

[0156] Figure 16 According to other exemplary embodiments of the present disclosure Figure 3 1 ', which schematically illustrates the wires used to electrically connect each sub-pixel in the first display area AA1 to its pixel driving circuit. In some embodiments of the present disclosure, in each of the first repeating units P1, the orthographic projection of the first via hole or first groove VH1 in each sub-pixel on the base substrate 1 is located at the same position relative to the center of the orthographic projection of the anode structure of the sub-pixel on the base substrate 1. For example, in the embodiment shown in FIG20 , relative to the center of the anode structure (i.e., the center of the circle), the orthographic projection of the first via hole or first groove VH1 in each sub-pixel on the base substrate 1 is located to the lower right of the center.

[0157] It should be noted that the "orientation" here can be understood as the relative positional relationship between the orthographic projection of a component (such as a via or groove) on the substrate and the orthographic projection of the center of the anode structure on the substrate 1 in the first direction X and the second direction Y.

[0158] Continue to refer to Figure 16 In each of the first repeating units P1, the first via holes or first grooves VH1 in each sub-pixel located in the same row are located on the same straight line along the first direction X. This arrangement facilitates the formation of the via holes or grooves by patterning during the manufacturing process of the array substrate.

[0159] Figure 17 FIG. 1 is a schematic plan view of a pixel driving circuit of a display substrate according to some exemplary embodiments of the present disclosure. Figure 18 is an equivalent circuit diagram of a pixel driving circuit of a display substrate according to some exemplary embodiments of the present disclosure.

[0160] Below, the structure of the pixel driving circuit is described in detail by taking the 7T1C pixel driving circuit as an example. However, the embodiments of the present disclosure are not limited to the 7T1C pixel driving circuit. Other known pixel driving circuit structures can be applied to the embodiments of the present disclosure unless there is a conflict.

[0161] like Figure 17 and Figure 18 As shown, the pixel driving circuit may include: multiple thin film transistors and a storage capacitor Cst. The pixel driving circuit is used to drive an organic light emitting diode (OLED). The multiple thin film transistors include a first transistor T1, a second transistor T2, a third transistor T3, a fourth transistor T4, a fifth transistor T5, a sixth transistor T6, and a seventh transistor T7. Each transistor includes a gate, a source, and a drain.

[0162] The display substrate may further include a plurality of signal lines, for example, the plurality of signal lines include: a scanning signal line 61 for transmitting a scanning signal Sn, a reset signal line 62 for transmitting a reset control signal RESET (i.e., a scanning signal of a previous row), a light-emitting control line 63 for transmitting a light-emitting control signal En, a data line 64 for transmitting a data signal Dm, a driving voltage line 65 for transmitting a driving voltage VDD, an initialization voltage line 66 for transmitting an initialization voltage Vint, and a power line 67 for transmitting a VSS voltage.

[0163] The gate electrode G1 of the first transistor T1 is electrically connected to one end Cst1 of the storage capacitor Cst, the source electrode S1 of the first transistor T1 is electrically connected to the driving voltage line 65 via the fifth transistor T5, and the drain electrode D1 of the first transistor T1 is electrically connected to the anode electrode of the OLED via the sixth transistor T6. The first transistor T1 receives the data signal Dm according to the switching operation of the second transistor T2 to supply the driving current Id to the OLED.

[0164] The gate G2 of the second transistor T2 is electrically connected to the scan signal line 61, the source S2 of the second transistor T2 is electrically connected to the data line 64, and the drain D2 of the second transistor T2 is electrically connected to the drive voltage line 65 via the fifth transistor T5, and is also electrically connected to the source S1 of the first transistor T1. The second transistor T2 is turned on in response to the scan signal Sn transmitted via the scan signal line 61 to perform a switching operation to transmit the data signal Dm transmitted to the data line 64 to the source S1 of the first transistor T1.

[0165] The gate G3 of the third transistor T3 is electrically connected to the scan signal line 61. The source S3 of the third transistor T3 is electrically connected to the anode of the OLED via the sixth transistor T6, and is also electrically connected to the drain D1 of the first transistor T1. The drain D3 of the third transistor T3 is electrically connected to one end (i.e., the first capacitor electrode) Cst1 of the storage capacitor Cst, the drain D4 of the fourth transistor T4, and the gate G1 of the first transistor T1. The third transistor T3 is turned on in response to the scan signal Sn transmitted via the scan signal line 61 to connect the gate G1 and drain D1 of the first transistor T1 to each other, thereby performing a diode connection for the first transistor T1.

[0166] The gate G4 of the fourth transistor T4 is electrically connected to the reset control signal line 62, and the source S4 of the fourth transistor T4 is electrically connected to the initialization voltage line 66. Furthermore, the drain D4 of the fourth transistor T4 is electrically connected to one end Cst1 of the storage capacitor Cst, the drain D3 of the third transistor T3, and the gate G1 of the first transistor T1. The fourth transistor T4 is turned on in response to the reset control signal Sn-1 transmitted via the reset control signal line 62 to transmit the initialization voltage Vint to the gate G1 of the first transistor T1, thereby performing an initialization operation to initialize the voltage of the gate G1 of the first transistor T1.

[0167] The gate G5 of the fifth transistor T5 is electrically connected to the light emission control line 63, the source S5 of the fifth transistor T5 is electrically connected to the driving voltage line 65, and the drain D5 of the fifth transistor T5 is electrically connected to the source S1 of the first transistor T1 and the drain D2 of the second transistor T2.

[0168] The gate G6 of the sixth transistor T6 is electrically connected to the light emission control line 63. The source S6 of the sixth transistor T6 is electrically connected to the drain D1 of the first transistor T1 and to the source S3 of the third transistor T3. The drain D6 of the sixth transistor T6 is electrically connected to the anode of the OLED. The fifth transistor T5 and the sixth transistor T6 are concurrently (e.g., simultaneously) turned on in response to the light emission control signal En transmitted via the light emission control line 63 to transmit the driving voltage ELVDD to the OLED, thereby allowing the driving current Id to flow into the OLED.

[0169] The seventh transistor T7 includes a gate G7 connected to the reset control signal line 62, a source S7 connected to the drain D6 of the sixth transistor T6 and the anode of the OLED, and a drain D7 connected to the initialization voltage line 66. The seventh transistor T7 transmits the reset control signal Sn-1 from the reset control signal line 62 to the gate G7.

[0170] The other end Cst2 of the storage capacitor Cst is electrically connected to the driving voltage line 65, and the cathode of the OLED is electrically connected to the power line 67 to receive the common voltage ELVSS. Accordingly, the OLED receives the driving current Id from the first transistor T1 to emit light, thereby displaying an image.

[0171] It should be noted that in Figure 18 , each thin film transistor T1, T2, T3, T4, T5, T6 and T7 is a p-channel field effect transistor, but the embodiments of the present disclosure are not limited thereto, and at least some of the thin film transistors T1, T2, T3, T4, T5, T6 and T7 may be an n-channel field effect transistor.

[0172] In operation, during the initialization phase, a reset control signal Sn-1 having a low level is supplied through the reset control signal line 62. Subsequently, the initialization thin film transistor T4 is turned on based on the low level of the reset control signal Sn-1, and the initialization voltage Vint from the initialization voltage line 66 is transmitted to the gate G1 of the driving thin film transistor T1 through the initialization thin film transistor T4. Therefore, the driving thin film transistor T1 is initialized due to the initialization voltage Vint.

[0173] During the data programming phase, a scan signal Sn having a low level is supplied through the scan signal line 61. Subsequently, the switching thin film transistor T2 and the compensation thin film transistor T3 are turned on based on the low level of the scan signal Sn. Therefore, the driving thin film transistor T1 is placed in a diode connection state through the turned-on compensation thin film transistor T3 and is biased in the forward direction.

[0174] Subsequently, a compensation voltage Dm+Vth (for example, Vth is a negative value) obtained by subtracting the threshold voltage Vth of the driving thin film transistor T1 from the data signal Dm supplied via the data line 64 is applied to the gate G1 of the driving thin film transistor T1. Subsequently, the driving voltage ELVDD and the compensation voltage Dm+Vth are applied to both terminals of the storage capacitor Cst, so that charges corresponding to the voltage difference between the corresponding terminals are stored in the storage capacitor Cst.

[0175] During the light emission period, the light emission control signal En from the light emission control line 63 changes from high level to low level. Subsequently, during the light emission period, the first light emission control thin film transistor T5 and the second light emission control thin film transistor T6 are turned on based on the low level of the light emission control signal En.

[0176] Then, a driving current is generated based on the difference between the voltage of the gate G1 of the driving thin film transistor T1 and the driving voltage ELVDD. A driving current Id corresponding to the difference between the driving current and the bypass current is supplied to the OLED through the second emission control thin film transistor T6.

[0177] During the light emitting phase, based on the current-voltage relationship of the driving thin film transistor T1, the gate-source voltage of the driving thin film transistor T1 is maintained at (Dm+Vth)-ELVDD due to the storage capacitor Cst. 2 Therefore, the driving current Id may not be affected by the change in the threshold voltage Vth of the driving thin film transistor T1.

[0178] For example, in conjunction with reference Figures 10 to 18 , the first pixel driving circuit 412 may adopt Figure 17 and Figure 18 In this case, the second end of the first connection line 110 can be electrically connected to the first pixel driving circuit 412 through the via hole VH2.

[0179] For example, the second pixel driving circuit 424 may be configured as Figure 17 and Figure 18 In this case, the positive projection of the anode structure of the sub-pixel located in the second display area AA2 on the base substrate 1 can cover the via hole VH3 (such as Figure 11 In this way, the anode structure of the sub-pixel located in the second display area AA2 is electrically connected to the second pixel driving circuit 424 through the via hole VH3.

[0180] For example, in various embodiments of the present disclosure, the base substrate 1 may be a glass substrate, a quartz substrate, a metal substrate, a resin substrate, etc., and may be a rigid substrate or a flexible substrate, which is not limited in the embodiments of the present disclosure.

[0181] 19A to 19C Shown respectively Figure 4 The extended diffraction simulation diagram, PSF (point spread function) simulation diagram and glare actual photograph of the first display area of the display substrate under the layout shown. 20A to 20C Shown respectively Figure 6 The extended diffraction simulation diagram, PSF (point spread function) simulation diagram and glare actual photograph of the first display area of the display substrate under the layout shown. Figures 21A to 21C Shown respectively Figure 7 The extended diffraction simulation diagram, PSF (point spread function) simulation diagram and glare real-time image of the first display area of the display substrate under the layout shown. Figures 19A to 21C It can be seen that in the embodiment of the present disclosure, in the first display area AA1, the anode structure of the first repeating unit and its corresponding light-emitting structure are concentrated and compacted. Accordingly, the spacing between each first repeating unit is increased, which can reduce the diffraction of light in the first display area and improve the glare phenomenon.

[0182] Return to reference Figure 1 and Figure 2 At least some embodiments of the present disclosure further provide a display device. The display device may include the display substrate described above and a sensor 2 (eg, a camera).

[0183] As described above, the display substrate has a first display area and a second display area, with the first display area having a higher pixel density than the second display area. Sensor 2 is located on the side of base substrate 1 facing away from the pixel array, with its photosensitive surface facing the display substrate. The orthographic projection of sensor 2 on base substrate 1 overlaps with the orthographic projection of second display area AA2 on said base substrate 1. For example, sensor 2 is located within the orthographic projection of second display area AA2 on base substrate 1. This allows imaging using light passing through the second display area, thereby realizing an under-screen camera function.

[0184] The sensor 2 can adopt a structure known in the art, for example, including a complementary metal oxide semiconductor (CMOS) image sensor or a charge coupled device (CCD) image sensor. The sensor 2 can be electrically connected to an image processor. In addition to the image sensor, in order to achieve better imaging effects, the imaging module including the image sensor can also include a lens assembly, for example. The lens assembly and the image sensor can be arranged in sequence along the optical axis of the lens assembly in a direction perpendicular to the substrate 1.

[0185] The display device may include any device or product with a display function. For example, the display device may be a smart phone, a mobile phone, an e-book reader, a desktop computer (PC), a laptop PC, a netbook PC, a personal digital assistant (PDA), a portable multimedia player (PMP), a digital audio player, a mobile medical device, a camera, a wearable device (such as a head-mounted device, electronic clothing, an electronic bracelet, an electronic necklace, an electronic accessory, an electronic tattoo, or a smart watch), a television, etc.

[0186] Although some embodiments of the overall technical concept of the present disclosure have been shown and described, those skilled in the art will understand that changes may be made to these embodiments without departing from the principles and spirit of the overall technical concept, and the scope of the present disclosure is defined by the claims and their equivalents.
