[0036] In the related art, a display substrate is usually formed by arranging a plurality of basic pixel units in an array. Based on the background technology, it can be known that with the increase in the demand for brightness, the current display substrate cannot effectively improve the brightness without changing the electroluminescent material. Figure 1 and Figure 2 As shown, Figure 1 is a schematic diagram of a top view structure of a display substrate provided by the related technology of this application, Figure 2 is along Figure 1 Schematic diagram of the cross-sectional structure obtained along the A-A' line, wherein the display substrate may include an anode layer 11 and a pixel defining layer 12 arranged on the anode layer 11, the anode layer 11 may include a plurality of anode patterns arranged in an array, the anode pattern is taken as a rectangle in the figure, the plurality of rectangular patterns are isolated by the pixel defining layer 12, and the pixel defining layer 12 includes an opening area for exposing the rectangular pattern, each opening area may define a basic pixel unit P0, and the basic pixel unit P0 is taken as a rectangle in the figure.
[0037] In order to effectively improve the brightness of a microdisplay without changing the electroluminescent material, an embodiment of the present application provides a display substrate, which may be provided with an electrical connection area for electrically connecting at least two adjacent anode patterns and a second opening area for exposing the electrical connection area, that is, an electrical connection area and a second opening area are formed between at least two adjacent basic pixel units (also referred to as first pixel units), thereby effectively improving the anode opening ratio and the hole injection capability, and effectively improving the brightness.
[0038] In some embodiments, the first pixel unit may be rectangular, see Figure 3 As shown, Figure 3 : is a schematic diagram of a top view structure of a display substrate obtained based on a rectangular first pixel unit provided in an embodiment of the present application, which may include:
[0039] The anode layer 31 includes a plurality of anode patterns arranged in an array;
[0040] The pixel defining layer 32 disposed on the anode layer 31 includes an opening region, wherein the opening region includes a plurality of first opening regions W1, each of which exposes an anode pattern to define a first pixel unit P1.
[0041] The opening area further includes a second opening area W2 connecting at least two adjacent first opening areas W1, and the anode layer 31 further includes an electrical connection area exposed by the second opening area W2, and the electrical connection area electrically connects the anode patterns exposed by at least two adjacent first opening areas W1;
[0042] The at least two adjacent first opening areas W1 connected by the second opening area W2 jointly define a second pixel unit P2.
[0043] In this embodiment, the electrical connection area electrically connects four adjacent anode patterns, and the second pixel unit P2 is defined by the second opening area W2 and the four adjacent first opening areas W1 connected thereto. In other embodiments, the second pixel unit P2 can be defined in other ways according to needs.
[0044] In some embodiments, Figure 3 As shown, the display substrate can be composed of a first pixel unit P1 and a second pixel unit P2 arranged in an array, wherein the first pixel unit P1 and the second pixel unit P2 are separated from each other. It should be noted that the array arrangement of the first pixel unit P1 and the second pixel unit P2 can be flexibly set according to requirements.
[0045] By providing an electrical connection area that electrically connects the anode patterns exposed by at least two adjacent first opening areas W1 and a second opening area W2 for exposing the electrical connection area, the anode opening ratio can be effectively improved by increasing the area of the light-transmitting part without changing the electroluminescent material, thereby improving the hole injection capability and effectively improving the brightness.
[0046] In other embodiments, in order to further improve the aperture ratio and effectively increase the brightness, the display substrate may be configured to be composed of a plurality of second pixel units P2 arranged in an array (not shown in the figure).
[0047] In some embodiments, the electrical connection area and the anode pattern electrically connected thereto may be integrated. As an example, a plurality of anode patterns arranged in one piece and an electrical connection area for connecting the plurality of anode patterns may be formed by a process such as chemical deposition or physical deposition, that is, the anode pattern and the electrical connection area are formed by the same deposition process.
[0048] In other embodiments, the electrical connection region and the anode pattern electrically connected thereto may be non-integrated, that is, the electrical connection region and the anode pattern may be formed separately using deposition processes, and their boundaries abut against each other to achieve electrical connection.
[0049] In some embodiments, the display substrate may further include a monochrome light-emitting material layer formed in the second opening area W2 and at least two adjacent first opening areas W1 connected thereto, the monochrome light-emitting material layer corresponding to the second pixel unit P2, that is, the projection of the monochrome light-emitting material layer on the anode layer 32 overlaps with the corresponding second pixel unit P2.
[0050] When the display substrate is composed of the first pixel unit P1 and the second pixel unit P2 , the display substrate may further include a monochromatic light emitting material layer formed in the first opening area W1 .
[0051] The display substrate provided in the embodiment of the present application can be applied to a monochrome display substrate. Accordingly, when the display substrate is composed of a first pixel unit P1 and a second pixel unit P2, the colors of the monochrome light-emitting material layers of the first pixel unit P1 and the second pixel unit P2 are the same; when the display substrate is composed of an array of second pixel units P2, the colors of the monochrome light-emitting material layers of multiple second pixel units P2 are the same.
[0052] In addition, the display substrate provided in the embodiment of the present application can also be applied to a color display substrate. Figure 3 The display substrate shown in the figure can obtain a color display substrate by setting the color of the monochromatic luminescent material layer of the first pixel unit P1 and the second pixel unit P2 to be different. Alternatively, for a display substrate composed of an array of second pixel units P2, a color display substrate can be obtained by setting the color of the monochromatic luminescent material layer of multiple second pixel units P2 to be different.
[0053] For the color display substrate, in order to improve the aperture ratio and display effect, the first pixel unit can be set to a hexagon. The hexagonal design is conducive to forming a more compact layout when splicing, reducing edge effects, thereby improving the display effect, making the display effect more uniform and delicate.
[0054] In some embodiments, the display substrate may be composed of a hexagonal first pixel unit and a second pixel unit connected based on the hexagonal first pixel unit, so as to facilitate the complementary arrangement of the first pixel unit and the second pixel unit and improve the pixel arrangement density and display effect.
[0055] For details, please refer to Figures 4 to 6 As shown, Figures 4 to 6 They are respectively schematic top-view structures of an anode layer, a pixel defining layer and a display substrate provided in embodiments of the present application.
[0056] The display substrate may include: an anode layer 41 and a pixel defining layer 42 disposed on the anode layer 41, wherein Figure 4 As shown, the anode layer 41 includes a plurality of anode patterns S1 arranged in an array, the pixel defining layer 42 includes an opening area, the opening area may include a first opening area W1' and a second opening area W2', a plurality of first opening areas W1' may be provided, each first opening area W1' is used to expose an anode pattern S1 to define a first pixel unit P1', the second opening area W2' is used to connect at least two adjacent first opening areas W1', the anode layer 41 may further include an electrical connection area S2 exposed by the second opening area W2', the electrical connection area S2 electrically connects the anode patterns S1 exposed by at least two adjacent first opening areas W1', and the at least two adjacent first opening areas W1' connected by the second opening area W2' jointly define a second pixel unit P2'.
[0057] In this embodiment, the shape of the anode pattern S1 is hexagonal, and a hexagonal first pixel unit P1 ′ can be defined by the first opening area W1 ′.
[0058] In some embodiments, the electrical connection area S2 and the anode pattern S1 electrically connected thereto may be integrated. As an example, a plurality of anode patterns S1 disposed integrally and an electrical connection area S2 for connecting the plurality of anode patterns S1 may be formed by a process such as chemical deposition or physical deposition, that is, the anode pattern S1 and the electrical connection area S2 are formed by the same deposition process.
[0059] In some other embodiments, the electrical connection region S2 and the anode pattern S1 electrically connected thereto may be non-integral, that is, the electrical connection region S2 and the anode pattern S1 may be formed separately by deposition processes, and their boundaries abut to achieve electrical connection.
[0060] In some embodiments, Figure 6As shown, the display substrate can be formed by arranging the first pixel units P1' and the second pixel units P2' in an array, where the first pixel units P1' and the second pixel units P2' are separated from each other. Among them, multiple anode patterns S1 can be arranged in a hexagonal array with intervals in the row direction and misaligned in the column direction. The second pixel unit P2' can be formed by connecting one first pixel unit P1' and two first pixel units P1' on adjacent rows, presenting an overall "pin" shape. Two adjacent first pixel units P1' located on one side of the second pixel unit P2' and misaligned in the column direction can be used as a first pixel unit group. In the array formed by the first pixel units P1' and the second pixel units P2', in the row direction, the first pixel unit group and the second pixel unit P2' can be arranged alternately, and the same arrangement pattern is repeated in each row.
[0061] In some other embodiments, the second pixel unit P2' can also be formed by connecting one pixel unit P1' and one first pixel unit P1' on an adjacent row. In other embodiments, the second pixel unit P2' can also be flexibly set according to actual requirements. Additionally, the first pixel units P1' and the second pixel units P2' can also be arranged in an array in other ways. For example, in the row direction, the first pixel unit group and the second pixel unit P2' can be arranged alternately, and two adjacent first pixel unit groups are misaligned in the column direction, and two adjacent second pixel units P2' are misaligned in the column direction.
[0062] In some embodiments, the display substrate can further include a monochromatic light-emitting material layer. Among them, the monochromatic light-emitting material layer formed in the second opening region W2' and at least two adjacent first opening regions W1' connected thereto corresponds to the second pixel unit P2', and the monochromatic light-emitting material layer formed only in the first opening region W1' corresponds to the first pixel unit P1'. The colors of the monochromatic light-emitting material layers of the first pixel unit P1' and the second pixel unit P2' are different. For example, the first pixel unit P1' can be a green pixel unit or a blue pixel unit, and the second pixel unit P2' can be a red pixel unit.
[0063] In some other embodiments, for a color display substrate, in order to improve the uniformity of pixel distribution while increasing the brightness, further reduce color deviation, and improve the display effect, the display substrate can be formed by arranging the second pixel units P2' in an array. Among them, the arrangement of the second pixel units P2' in the array includes: the upright second pixel units P2' and the inverted second pixel units P2' are arranged alternately in the row direction, the upright second pixel units P2' and the inverted second pixel units P2' are misaligned in the column direction, and the corresponding sides of any second pixel unit P2' and the adjacent second pixel unit P2' are complementary in shape.
[0064] For details, please refer to Figure 7 as shown. Figure 7 FIG. Figure 7 is a top view structural schematic diagram of a display substrate provided by another embodiment of the present application. The second pixel unit P2' can also be formed by connecting one first pixel unit P1' and two first pixel units P1' on adjacent rows, forming a "pin" shape as a whole. The upright second pixel unit P2' is an upright "pin" shape, and the inverted second pixel unit P2' is an inverted "pin" shape.
[0065] In some embodiments, the display substrate may further include a monochromatic light-emitting material layer formed in the second opening region W2' and at least two adjacent first opening regions W1' connected thereto. The monochromatic light-emitting material layer corresponds to the second pixel unit P2', that is, the projection of the monochromatic light-emitting material layer on the anode layer 42 overlaps with the corresponding second pixel unit P2'. The colors of the monochromatic light-emitting material layers of adjacent second pixel units P2' are different. For example, the colors of the monochromatic light-emitting material layers of multiple second pixel units P2' can be red, green, or blue respectively. By setting multiple second pixel units P2' with the same shape and arranging the second pixel units P2' with different colors, it is beneficial to improve the uniformity of color display while ensuring brightness and avoiding color deviation.
[0066] It should be noted that the shape and arrangement of the pixel units have relatively little influence on the display effect of the monochromatic display substrate. The first pixel unit, the second pixel unit, and the arrangement of each pixel unit can be set according to actual needs. For example, in addition to the setting method in Figure 3 , the setting method in Figure 6 or Figure 7 can also be adopted.
[0067] In some embodiments, the display substrate may further include a cathode, a packaging layer, a planarization layer, and a lens. Refer to Figure 8 shown in Figure 8 FIG.
