[0005] At least one embodiment of the present disclosure provides a display panel, comprising a base substrate; a driving circuit layer, which is arranged on the base substrate and includes a plurality of pixel driving circuits; a light-emitting device layer, which is arranged on a side of the driving circuit layer away from the base substrate and includes a plurality of light-emitting devices; and a color filter layer, which is arranged on a side of the light-emitting device layer away from the base substrate and includes a plurality of color filter patterns, wherein the display panel comprises a plurality of sub-pixels, each of the plurality of sub-pixels comprises at least one pixel driving circuit in the driving circuit layer, at least one light-emitting device in the light-emitting device layer and at least one color filter pattern in the color filter layer, the plurality of color filter patterns comprising a plurality of first color filter patterns, a plurality of second color filter patterns and a plurality of third color filter patterns, so that the plurality of sub-pixels become a plurality of first color sub-pixels, a plurality of second color sub-pixels and a plurality of third color sub-pixels, and the light-emitting areas of the plurality of first color sub-pixels and the light-emitting areas of the plurality of second color sub-pixels are parallel to the base substrate. The substrate is alternately arranged in a first direction to form a plurality of first sub-pixel rows; the light-emitting areas of the plurality of third color sub-pixels are arranged along the first direction to form a plurality of second sub-pixel rows, the first sub-pixel rows and the second sub-pixel rows are alternately arranged along a second direction parallel to the base substrate and crossing the first direction, the plurality of first sub-pixel rows and the plurality of second sub-pixel rows include a sub-pixel row group consisting of a first sub-pixel row, a second sub-pixel row, a first sub-pixel row, a second sub-pixel row and a first sub-pixel row arranged in sequence, the first sub-pixel row located in the middle of the sub-pixel row group is a middle first sub-pixel row, the two second sub-pixel rows in the sub-pixel row group are adjacent second sub-pixel rows, the two outermost first sub-pixel rows in the pixel row group are outer first sub-pixel rows, and the first color filter pattern of the first color sub-pixel in the middle first pixel row extends across the adjacent second sub-pixel row and further extends to the outer first sub-pixel row.

[0006] For example, in the display panel provided in one embodiment of the present disclosure, the first color filter pattern of the first color sub-pixel in the middle first sub-pixel row overlaps with the third color filter pattern of the third color sub-pixel in the adjacent second sub-pixel row that is closest to the first color sub-pixel, and overlaps with the second color filter pattern of the second color sub-pixel in the outer first sub-pixel row that is closest to the first color sub-pixel.

[0007] For example, in the display panel provided in one embodiment of the present disclosure, the first color film pattern of the first color sub-pixel in the middle first sub-pixel row overlaps with the third color film pattern of the two third color sub-pixels in the adjacent second sub-pixel row located on one side of the middle first sub-pixel row, and overlaps with the third color film pattern of the two third color sub-pixels in the adjacent second sub-pixel row located on the other side of the middle first sub-pixel row.

[0008] For example, in the display panel provided in one embodiment of the present disclosure, the first color film pattern of the first color sub-pixel in the middle first sub-pixel overlaps with the second color film pattern of one of the second color sub-pixels in the outer first sub-pixel row located on one side of the middle first sub-pixel row, and overlaps with the second color film pattern of one of the second color sub-pixels in the outer first sub-pixel row located on the other side of the middle first sub-pixel row.

[0009] For example, in the display panel provided by an embodiment of the present disclosure, the first color filter pattern of each first color sub-pixel in the middle first sub-pixel row is continuously distributed.

[0010] For example, in the display panel provided in one embodiment of the present disclosure, in the sub-pixel row group, a straight line along the second direction and passing through the center of the first color filter pattern in the middle first sub-pixel row passes through the second color filter pattern in the outer first sub-pixel row; a straight line along the second direction and passing through the center of the second color filter pattern in the middle first sub-pixel row passes through the first color filter pattern in the outer first sub-pixel row.

[0011] For example, in the display panel provided in one embodiment of the present disclosure, in the sub-pixel row group, a straight line along the second direction and passing through the center of the third color filter pattern in the adjacent second sub-pixel row is located between the first color filter pattern and the second color filter pattern in the outer first sub-pixel row, and is also located between the first color filter pattern and the second color filter pattern in the middle first sub-pixel row.

[0012] For example, in the display panel provided in one embodiment of the present disclosure, in the sub-pixel row group, the first color film pattern of the first color sub-pixel in the middle first sub-pixel row extends to between the light-emitting areas of the adjacent second color sub-pixels and the adjacent third color sub-pixels in the adjacent second sub-pixel row and the outer first sub-pixel row.

[0013] For example, in the display panel provided in an embodiment of the present disclosure, in the sub-pixel row group, along a direction parallel to a line connecting the centers of the luminous areas of the adjacent second color sub-pixels and the third color sub-pixels in the adjacent second sub-pixel row and the outer first sub-pixel row, the minimum size of a portion of the first color film pattern located between the luminous areas of the adjacent second color sub-pixels and the third color sub-pixels is greater than or equal to 7 μm.

[0014] For example, in the display panel provided in an embodiment of the present disclosure, in the sub-pixel row group, a line connecting the centers of the light-emitting areas of adjacent second-color sub-pixels and third-color sub-pixels does not overlap with the first color filter pattern.

[0015] For example, in the display panel provided in one embodiment of the present disclosure, in the overlapping area of ​​the first color filter pattern and the third color filter pattern, the first color filter pattern is located on the side of the second color filter pattern away from the base substrate; in the overlapping area of ​​the first color filter pattern and the third color filter pattern, the first color filter pattern is located on the side of the third color filter pattern away from the base substrate.

[0016] For example, in a display panel provided in an embodiment of the present disclosure, the first color sub-pixel is a red sub-pixel, the second color sub-pixel is a blue sub-pixel, and the third color sub-pixel is a green sub-pixel.

[0017] For example, in the display panel provided in one embodiment of the present disclosure, in the sub-pixel row group, the area where the first color filter pattern and the second color filter pattern overlap with each other includes a strip area extending along the edge of the second color filter pattern, and the area where the first color filter pattern and the third color filter pattern overlap with each other includes a strip area extending along the edge of the third color filter pattern.

[0018] For example, in the display panel provided in one embodiment of the present disclosure, the orthographic projections of the second color filter pattern and the third color filter pattern on the base substrate are roughly circular, the boundary of the overlapping part of the first color filter pattern and the third color filter pattern facing the center of the third color filter pattern is an arc, and the boundary of the overlapping part of the first color filter pattern and the second color filter pattern facing the center of the second color filter pattern is an arc.

[0019] For example, the display panel provided in an embodiment of the present disclosure also includes: a black matrix layer, which is arranged on a side of the light-emitting device layer away from the base substrate, and the black matrix layer has a plurality of avoidance openings that respectively expose the light-emitting areas of the light-emitting devices of the plurality of sub-pixels in a direction perpendicular to the base substrate, and the plurality of avoidance openings include a plurality of first avoidance openings, a plurality of second avoidance openings and a plurality of third avoidance openings corresponding to the plurality of first color sub-pixels, the plurality of second color sub-pixels and the plurality of third color sub-pixels, respectively, and the plurality of first color film patterns, the plurality of second color film patterns and the plurality of third color film patterns of the plurality of color film patterns respectively cover the plurality of first avoidance openings, the plurality of second avoidance openings and the plurality of third avoidance openings.

[0020] For example, in the display panel provided in an embodiment of the present disclosure, the minimum distance between the boundary of the orthographic projection of the color filter pattern on the base substrate and the boundary of the orthographic projection of the avoidance opening covered by the color filter pattern on the base substrate is greater than or equal to 4 μm.

[0021] For example, in the display panel provided in one embodiment of the present disclosure, the driving circuit layer includes a plurality of light-transmitting areas, and the black matrix layer also includes a plurality of light-transmitting openings. Each of the plurality of light-transmitting openings is arranged corresponding to at least one of the plurality of light-transmitting areas for transmitting light within a predetermined angle range with respect to the display panel. The light-transmitting opening is located between the first avoidance opening and the second avoidance opening adjacent to each other in the first direction.

[0022] For example, in the display panel provided in an embodiment of the present disclosure, in a direction perpendicular to the base substrate, the color filter pattern and the light-transmitting opening do not overlap.

[0023] For example, in the display panel provided in one embodiment of the present disclosure, in the sub-pixel row group, a portion of the first color film pattern of the first color sub-pixel in the middle first sub-pixel row extends between the adjacent light-transmitting opening and the light-emitting area of ​​the third color sub-pixel, and this portion of the first color film pattern overlaps with the third color film pattern of the third color sub-pixel in the second direction.

[0024] For example, in the display panel provided in an embodiment of the present disclosure, the minimum distance between the boundary of the orthographic projection of the color filter pattern on the base substrate and the boundary of the orthographic projection of the light-transmitting opening on the base substrate is greater than or equal to 1.3 μm.

[0025] For example, in the display panel provided by an embodiment of the present disclosure, it also includes a planarization layer arranged on the side of the driving circuit layer away from the substrate substrate and a pixel defining layer located on the side of the planarization layer away from the substrate substrate, wherein the pixel defining layer includes a plurality of sub-pixel openings and a plurality of photosensitive openings, and the light-emitting device includes a first electrode layer, a light-emitting material layer, and a second electrode layer stacked in sequence in a direction away from the substrate substrate, the first electrode layer is arranged on the side of the planarization layer away from the substrate substrate, and the pixel defining layer is arranged on the side of the first electrode layer away from the substrate substrate, and the plurality of sub-pixel openings respectively expose the first electrode layer of the light-emitting devices of the plurality of sub-pixels, and the plurality of sub-pixel openings define the light-emitting areas of the plurality of sub-pixels. For a sub-pixel opening and an avoidance opening corresponding to the same sub-pixel, the orthographic projection of the sub-pixel opening on the substrate substrate is located inside the orthographic projection of the avoidance opening on the substrate substrate. For a photosensitive opening and a light-transmitting opening corresponding to the same light-transmitting area, the orthographic projection of the photosensitive opening on the substrate substrate is located inside the orthographic projection of the light-transmitting opening on the substrate substrate.

[0026] For example, in the display panel provided in an embodiment of the present disclosure, the minimum distance between the boundary of the orthographic projection of the photosensitive opening on the base substrate and the boundary of the orthographic projection of the light-transmitting opening on the base substrate is greater than or equal to 1 μm.

[0027] For example, in a display panel provided in an embodiment of the present disclosure, the multiple sub-pixel openings include multiple first-color sub-pixel openings corresponding to the multiple first-color sub-pixels, multiple second-color sub-pixel openings corresponding to the multiple second-color sub-pixels, and multiple third-color sub-pixel openings corresponding to the multiple third-color sub-pixels. The positive projection of the first-color sub-pixel opening on the substrate is approximately elliptical. The first sub-pixel row includes a first type of first sub-pixel row. The major axis of the ellipse of the first color sub-pixel opening in the first type of first sub-pixel row extends approximately along the first direction. In the first type of first sub-pixel row, the two photosensitive openings adjacent to the first color sub-pixel opening are symmetrical about the minor axis of the ellipse of the first color sub-pixel opening, and the two photosensitive openings adjacent to the second color sub-pixel opening are symmetrical about a straight line along the second direction and passing through the center of the second color sub-pixel opening.

[0028] For example, in the display panel provided in one embodiment of the present disclosure, the first sub-pixel row includes a second type of first sub-pixel row, the major axis of the ellipse of the first color sub-pixel opening in the second type of first sub-pixel row extends approximately along the second direction, and in the second type of first sub-pixel row, two photosensitive openings adjacent to the second color sub-pixel opening are symmetrical about a straight line along the second direction and passing through the center of the second color sub-pixel opening.

[0029] For example, in the display panel provided in one embodiment of the present disclosure, the maximum size of the photosensitive openings in the first direction between the sub-pixels located in the second type of first sub-pixel row is larger than the maximum size of the photosensitive openings in the first direction between the sub-pixels located in the first type of first sub-pixel row.

[0030] For example, in the display panel provided in one embodiment of the present disclosure, the opening area of ​​the second color sub-pixel opening is larger than the opening area of ​​the first color sub-pixel opening, and the minimum distance between the edge of the photosensitive opening close to the first color sub-pixel opening and the corresponding light-transmitting area is smaller than the minimum distance between the edge of the photosensitive opening close to the second color sub-pixel opening and the light-transmitting area.

[0031] For example, the display panel provided in one embodiment of the present disclosure further includes: a touch layer, which is arranged on a side of the pixel defining layer away from the base substrate; the touch layer includes a plurality of touch lines, the orthographic projections of the plurality of touch lines on the base substrate are staggered from the orthographic projections of the avoidance opening and the light-transmitting opening on the base substrate, the plurality of touch lines are cross-arranged to form a mesh structure, the minimum distance between the boundary of the orthographic projection of the touch lines on the base substrate and the boundary of the orthographic projection of the light-transmitting opening on the base substrate is greater than or equal to 1.7 μm, and the minimum distance between the boundary of the orthographic projection of the touch lines on the base substrate and the boundary of the orthographic projection of the avoidance opening on the base substrate is greater than or equal to 1.7 μm.

[0032] At least one embodiment of the present disclosure provides a display device, comprising any of the above-mentioned display panels.

[0033] For example, the display device provided in one embodiment of the present disclosure also includes: a photosensitive device located on the non-display side of the display panel, and the photosensitive device is configured to emit light to the display side of the display panel through the light-transmitting area of ​​the driving circuit layer and / or receive light transmitted from the display side of the display panel through the light-transmitting area of ​​the driving circuit layer to the non-display side of the display panel.

[0034] By extending the first color filter pattern, the area of ​​the first color filter pattern can be increased, thereby better absorbing the light incident on the display panel and better reducing the reflectivity of the display panel to external light, thereby improving the display effect of the display panel.

[0046] 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 of the embodiments of the present disclosure. 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.

[0047] Unless otherwise defined, the technical or scientific terms used in this disclosure should have the usual meanings understood by persons of ordinary skill in the field to which this disclosure belongs. The words "first", "second" and similar terms used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Words such as "include" or "comprise" mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0048] Unless otherwise defined, the features such as "parallel", "perpendicular" and "same" used in the embodiments of the present disclosure include the cases of "parallel", "perpendicular", "same" in a strict sense, as well as the cases of "approximately parallel", "approximately perpendicular", "approximately the same" and the like which contain certain errors. For example, the above-mentioned "approximately" may mean that the difference between the compared objects is 10% of the average value of the compared objects, or within 5%. When the number of a component or element is not specifically indicated below in the embodiments of the present disclosure, it means that the component or element may be one or more, or may be understood as at least one. "At least one" refers to one or more, and "multiple" refers to at least two. The "same-layer arrangement" in the embodiments of the present disclosure refers to the relationship between multiple film layers formed by the same material after the same step (for example, a one-step patterning process). The "same layer" here does not always mean that the thickness of multiple film layers is the same or the height of multiple film layers in the cross-sectional view is the same.

[0049] To prevent glare, traditional OLED display panels typically incorporate a polarizer to improve viewing comfort in ambient light. However, the transmittance of polarizers is typically only around 40%, resulting in low light extraction efficiency and, in turn, higher power consumption.

[0050] In some embodiments, COE (Color film On Encapsulation) technology can be used, that is, the technology of replacing the polarizer with a color film (CF) to improve the light extraction rate of the display panel, and this technology is conducive to the development of the display panel towards high integration and thinness. In the COE technology, a black matrix layer is formed on the display panel, and the black matrix layer has an avoidance opening corresponding to the light-emitting area of ​​the light-emitting device of the sub-pixel to pass the light emitted by the light-emitting device of the sub-pixel. The above-mentioned color film is arranged in the avoidance opening, which can not only achieve a light filtering effect, but also absorb the light incident on the display panel, reduce the reflectivity of the display panel to external light, and improve the display effect of the display panel. In some other embodiments, the black matrix layer and the color film can also be set separately, and only the black matrix layer or the color film can be provided. For example, a black matrix layer may not be provided in the display panel, and color filters of different colors may be superimposed on each other to form a color filter layer. The light emitted by the light-emitting device of the sub-pixel passes through the color filter, which performs a filtering effect and absorbs the light entering the display panel. For example, a color filter may not be provided in the display panel, and the black matrix layer may be, for example, a grayscale filter, thereby absorbing the light entering the display panel.

[0051] Embodiments of the present disclosure provide a display panel and a display device. The display panel includes a base substrate, a drive circuit layer disposed on the base substrate, a light-emitting device layer disposed on a side of the drive circuit layer away from the base substrate, and a color filter layer disposed on a side of the light-emitting device layer away from the base substrate. The drive circuit layer includes multiple pixel drive circuits, the light-emitting device layer includes multiple light-emitting devices, and the color filter layer includes multiple color filter patterns. The display panel includes multiple sub-pixels, each of which includes at least one pixel drive circuit in the drive circuit layer, at least one light-emitting device in the light-emitting device layer, and at least one color filter pattern in the color filter layer.

[0052] The plurality of color filter patterns include a plurality of first color filter patterns, a plurality of second color filter patterns, and a plurality of third color filter patterns, such that the plurality of sub-pixels become a plurality of first color sub-pixels, a plurality of second color sub-pixels, and a plurality of third color sub-pixels. The light-emitting regions of the plurality of first color sub-pixels and the light-emitting regions of the plurality of second color sub-pixels are alternately arranged along a first direction parallel to the base substrate to form a plurality of first sub-pixel rows; the light-emitting regions of the plurality of third color sub-pixels are arranged along the first direction to form a plurality of second sub-pixel rows. The first sub-pixel rows and the second sub-pixel rows are alternately arranged along a second direction parallel to the base substrate and intersecting the first direction.

[0053] The plurality of first sub-pixel rows and the plurality of second sub-pixel rows include a sub-pixel row group consisting of a first sub-pixel row, a second sub-pixel row, a first sub-pixel row, a second sub-pixel row, and a first sub-pixel row arranged in sequence. The first sub-pixel row located in the middle of the sub-pixel row group is the middle first sub-pixel row, the two second sub-pixel rows in the sub-pixel row group are adjacent second sub-pixel rows, and the two first sub-pixel rows located on the outermost sides of the sub-pixel row group are the outer first sub-pixel rows. The first color filter pattern of the first color sub-pixel in the middle first sub-pixel row extends across the adjacent second sub-pixel row and further extends to the outer first sub-pixel row. By extending the first color filter pattern, the area of ​​the first color filter pattern can be increased, thereby better absorbing light incident on the display panel and better reducing the reflectivity of the display panel to external light, thereby improving the display effect of the display panel.

[0054] It should be noted that, when describing that the first color filter pattern extends across or extends to a certain pixel row, the pixel row can be regarded as a strip area extending along the row direction. For example, the first sub-pixel row can be a strip area extending along the first direction, and the upper and lower boundaries of the strip area pass through the end points of the second color filter pattern of the second color sub-pixel that are opposite to each other in the second direction; the second sub-pixel row can be a strip area extending along the first direction X, and the upper and lower boundaries of the strip area pass through the end points of the third color filter pattern of the third color sub-pixel that are opposite to each other in the second direction. Under this definition, the first pixel row and the second pixel row can partially overlap. In addition, extending to a certain pixel row can be extending to the boundary of the above-mentioned strip area, or extending into the interior of the above-mentioned strip area.

[0055] Below, the display panel and the display device provided by the embodiments of the present disclosure are described in detail with reference to the accompanying drawings.

[0056] One embodiment of the present disclosure provides a display panel. FIG1A is a plan view schematically illustrating a stack of a black matrix layer and a color filter layer of a display panel provided in at least one embodiment of the present disclosure; FIG1B is a cross-sectional view schematically illustrating a display panel provided in at least one embodiment of the present disclosure. As shown in FIG1A and FIG1B , the display panel includes a base substrate 101, a driving circuit layer 102 disposed on the base substrate 101, a light-emitting device layer disposed on a side of the driving circuit layer 102 away from the base substrate 101, and a color filter layer 114 disposed on a side of the light-emitting device layer away from the base substrate 101. The driving circuit layer 102 includes a plurality of pixel driving circuits, the light-emitting device layer includes a plurality of light-emitting devices EM, and the color filter layer 114 includes a plurality of color filter patterns 1140. The display panel includes a plurality of sub-pixels, each of the plurality of sub-pixels including at least one pixel driving circuit in the driving circuit layer 102, at least one light-emitting device EM in the light-emitting device layer, and at least one color filter pattern 1140 in the color filter layer 114. In order to clearly show the multiple color filter patterns 1140 of the color filter layer 114 , FIG. 1A only shows a partial structure of the stacked layers of the black matrix layer and the color filter layer of the display panel.

[0057] For example, as shown in FIG1B , the pixel driving circuit includes at least one thin-film transistor (TFT) and a storage capacitor (Cst). The thin-film transistor (TFT) includes an active layer (1021), a gate (1022), a source (1024), and a drain (1023) disposed on a base substrate (101). The drain (1023) of the thin-film transistor (TFT) is electrically connected to the first electrode layer (104) of the light-emitting device (EM). The storage capacitor (Cst) includes a first capacitor electrode (C1) and a second capacitor electrode (C2) disposed on the base substrate (101). The first capacitor electrode (C1) and the gate (1022) are disposed on the same layer, and the second capacitor electrode (C2) is disposed on a side of the first capacitor electrode (C1) away from the base substrate (101).

[0058] For example, as shown in FIG1B , the display panel may further include a buffer layer 103 disposed on the base substrate 101, a first gate insulating layer 1025 disposed on the active layer 1021, a second gate insulating layer 1026 disposed on the gate electrode 1022 and the first capacitor electrode C1, an interlayer insulating layer 1027 disposed on the second capacitor electrode CE2, a passivation layer 1028 disposed on the source electrode 1023 and the drain electrode 1024, and the like.

[0059] For example, the pixel driving circuit can be formed into a structure such as 2T1C (two thin film transistors and one storage capacitor), 6T1C (six thin film transistors and one storage capacitor), etc., thereby including multiple thin film transistors, which have a stacked structure similar to or the same as the thin film transistor shown in Figure 1B. Figure 1B only shows the thin film transistor directly connected to the light-emitting device. The thin film transistor can be a driving thin film transistor or a light-emitting control thin film transistor, etc.

[0060] For example, as shown in FIG1A , the plurality of color filter patterns 1140 include a plurality of first color filter patterns 1140a, a plurality of second color filter patterns 1140b, and a plurality of third color filter patterns 1140c, so that the plurality of sub-pixels form a plurality of first color sub-pixels, a plurality of second color sub-pixels, and a plurality of third color sub-pixels. For example, the sub-pixels corresponding to the first color filter pattern 1140a form first color sub-pixels, the sub-pixels corresponding to the second color filter pattern 1140b form second color sub-pixels, and the sub-pixels corresponding to the third color filter pattern 1140c form third color sub-pixels. The light-emitting regions of the plurality of first color sub-pixels and the light-emitting regions of the plurality of second color sub-pixels are alternately arranged along a first direction X parallel to the base substrate 101 to form a plurality of first sub-pixel rows; the light-emitting regions of the plurality of third color sub-pixels are arranged along the first direction X to form a plurality of second sub-pixel rows. The first sub-pixel rows and the second sub-pixel rows are alternately arranged along a second direction Y parallel to the base substrate 101 and intersecting the first direction X. For example, the second direction Y can be perpendicular to the first direction X.

[0061] The plurality of first subpixel rows and the plurality of second subpixel rows include a subpixel row group Gr consisting of a first subpixel row, a second subpixel row, a first subpixel row, a second subpixel row, and a first subpixel row arranged sequentially. The middle first subpixel row in the subpixel row group Gr is the middle first subpixel row Gr11, the two second subpixel rows in the subpixel row group Gr are adjacent second subpixel rows Gr12, and the two outermost first subpixel rows in the subpixel row group Gr are the outer first subpixel row Gr13. The first color filter pattern 1140a of the first color subpixel in the middle first subpixel row Gr11 extends across the adjacent second subpixel row Gr12 and further into the outer first subpixel row Gr13. By extending the first color filter pattern 1140a, the area of ​​the first color filter pattern 1140a is increased, thereby better absorbing light incident on the display panel and reducing the reflectivity of the display panel to external light, thereby improving the display quality of the display panel.

[0062] It should be noted that when describing that the first color filter pattern 1140a extends across or extends to a certain pixel row, the pixel row can be regarded as a strip area extending along the row direction. For example, the first sub-pixel row can be a strip area extending along the first direction X, and the upper and lower boundaries of the strip area pass through the opposite end points of the second color filter pattern 1140b of the second color sub-pixel in the second direction Y; the second sub-pixel row can be a strip area extending along the first direction X, and the upper and lower boundaries of the strip area pass through the opposite end points of the third color filter pattern 1140c of the third color sub-pixel in the second direction Y. Under this definition, the first pixel row and the second pixel row can partially overlap. In addition, extending to a certain pixel row can mean extending to the boundary of the above-mentioned strip area, or extending into the interior of the above-mentioned strip area. As shown in FIG1A , the first sub-pixel row is a strip region Re1 extending along the first direction X. The upper and lower boundaries of the strip region Re1 in the second direction Y are defined by the two endpoints of the second color filter pattern 1140b of the second color sub-pixel in the first pixel row that are furthest apart in the second direction Y. For example, the size of the strip region Re1 in the second direction Y is the largest size among the sizes of all the second color filter patterns 1140b in the first pixel row in the second direction Y. The second sub-pixel row is a strip region Re2 extending along the first direction X. The upper and lower boundaries of the strip region Re2 in the second direction Y are defined by the two endpoints of the third color filter pattern 1140c of the third color sub-pixel in the second pixel row that are furthest apart in the second direction Y. For example, the size of the strip region Re2 in the second direction Y is the largest size among the sizes of all the third color filter patterns 1140b in the second pixel row in the second direction Y. As described above, the description of the first pixel row and the second pixel row here is applicable to describing the extension range of the first color filter pattern, but the embodiments of the present disclosure are not limited to other aspects in which the first pixel row and the second pixel row have other meanings.

[0063] In some examples, as shown in FIG1A , the first color filter pattern 1140a of the first color sub-pixel in the middle first sub-pixel row Gr11 overlaps with the third color filter pattern 1140c of the third color sub-pixel closest to the first color sub-pixel in the adjacent second sub-pixel row Gr12, and overlaps with the second color filter pattern 1140b of the second color sub-pixel closest to the first color sub-pixel in the outer first sub-pixel row Gr13. Thus, the first color filter pattern 1140a overlaps with the second color filter pattern 1140b and the third color filter pattern 1140c, further increasing the area of ​​the first color filter pattern 1140a, thereby better absorbing light incident on the display panel.

[0064] In some examples, as shown in FIG1A , the first color filter pattern 1140a of the first color sub-pixel in the middle first sub-pixel row Gr11 overlaps with the third color filter pattern 1140c of two third color sub-pixels in the adjacent second sub-pixel row Gr12 located on one side of the middle first sub-pixel row Gr11, and overlaps with the third color filter pattern 1140c of two third color sub-pixels in the adjacent second sub-pixel row Gr12 located on the other side of the middle first sub-pixel row Gr11. Thus, the first color filter pattern 1140a can overlap with multiple third color filter patterns 1140c in the adjacent second sub-pixel rows Gr12 on both sides, further increasing the area of ​​the first color filter pattern 1140a and thereby better absorbing light incident on the display panel.

[0065] For example, as shown in FIG1A , the two third color sub-pixels in the adjacent second sub-pixel row Gr12 located on one side of the middle first sub-pixel row Gr11 are at the same distance from the first color sub-pixel. For example, the two third color sub-pixels in the adjacent second sub-pixel row Gr12 located on the other side of the middle first sub-pixel row Gr11 are at the same distance from the first color sub-pixel.

[0066] In some examples, as shown in FIG1A , the first color filter pattern 1140a of the first color sub-pixel in the middle first sub-pixel row Gr11 overlaps with the second color filter pattern 1140b of a second color sub-pixel in the outer first sub-pixel row Gr13 located on one side of the middle first sub-pixel row Gr11, and overlaps with the second color filter pattern 1140b of a second color sub-pixel in the outer first sub-pixel row Gr13 located on the other side of the middle first sub-pixel row Gr11. Thus, the first color filter pattern 1140a can overlap with multiple second color filter patterns 1140b in the outer first sub-pixel rows Gr13 on both sides, further increasing the area of ​​the first color filter pattern 1140a and thereby better absorbing light incident on the display panel.

[0067] In some examples, as shown in FIG1A , the first color filter patterns 1140a of each first color sub-pixel in the middle first sub-pixel row Gr11 are continuously distributed. This can further increase the area of ​​the first color filter patterns 1140a, thereby better absorbing light incident on the display panel. For example, as shown in FIG1A , the first color filter patterns 1140a of the first color sub-pixels in the middle first sub-pixel row Gr11 are alternately distributed along the first direction X.

[0068] In some examples, as shown in FIG1A , in the sub-pixel row group Gr, a straight line L1 along the second direction Y and passing through the center of the first color filter pattern 1140a in the middle first sub-pixel row Gr11 passes through the second color filter pattern 1140b in the outer first sub-pixel row Gr13. For example, the first color filter pattern 1140a and the second color filter pattern 1140b are arranged alternately along the second direction Y. Thus, the light-emitting areas of the light-emitting devices of the sub-pixels can be more reasonably arranged according to the size and dimensions of the light-emitting areas of the light-emitting devices of different sub-pixels, thereby increasing the area of ​​the first color filter pattern 1140a.

[0069] In some examples, as shown in FIG1A , in the subpixel row group Gr, a straight line L2 along the second direction Y and passing through the center of the second color filter pattern 1140 b in the middle first subpixel row Gr11 passes through the first color filter pattern 1140 a in the outer first subpixel row Gr13 .

[0070] For example, as shown in FIG1A , in the sub-pixel row group Gr, a straight line L1 along the second direction Y and passing through the center of the first color filter pattern 1140a in the middle first sub-pixel row Gr11 passes through the center of the second color filter pattern 1140b in the outer first sub-pixel row Gr13. For example, a straight line L2 along the second direction Y and passing through the center of the first color filter pattern 1140a in the middle first sub-pixel row Gr11 passes through the center of the second color filter pattern 1140b in the outer first sub-pixel row Gr13.

[0071] In some examples, as shown in FIG1A , in a sub-pixel row group Gr, a straight line L3, which runs along the second direction Y and passes through the center of the third color filter pattern 1140c in the adjacent second sub-pixel row Gr12, is located between the first color filter pattern 1140a and the second color filter pattern 1140b in the outer first sub-pixel row Gr13, and also between the first color filter pattern 1140a and the second color filter pattern 1140b in the middle first sub-pixel row Gr11. Thus, the light-emitting areas of the light-emitting devices of different sub-pixels can be more reasonably arranged according to their respective sizes, thereby increasing the area of ​​the first color filter pattern 1140a.

[0072] Figure 2 is a partially enlarged schematic diagram of Figure 1A . As shown in both Figures 1A and 2 , within the subpixel row group Gr, the first color filter pattern 1140a of the first color subpixel in the center first subpixel row Gr11 extends between the light-emitting regions of the adjacent second and third color subpixels in the adjacent second subpixel row Gr12 and the outer first subpixel row Gr13. This further increases the area of ​​the first color filter pattern 1140a, enabling better absorption of light incident on the display panel.

[0073] In some examples, as shown in Figures 1A and 2 , in a subpixel row group Gr, along a line L4 connecting the centers of the light-emitting areas of adjacent second and third color subpixels in the adjacent second subpixel row Gr12 and the outer first subpixel row Gr13, the minimum dimension D1 of the portion of the first color filter pattern 1140a located between the light-emitting areas of adjacent second and third color subpixels is greater than or equal to 7 μm. This can meet the process requirements of the color filter pattern 1140 and maximize the area of ​​the first color filter pattern 1140a.

[0074] In some examples, as shown in FIG1A and FIG2 , in a subpixel row group Gr, a first color filter pattern 1140a located between the light-emitting regions of adjacent second and third color subpixels can overlap with both the second and third color filter patterns 1140b and 1140c of the adjacent second and third color subpixels. This can further increase the area of ​​the first color filter pattern 1140a.

[0075] In some examples, as shown in Figures 1A and 2, in a subpixel row group Gr, the center line L4 connecting the light-emitting areas of adjacent second and third color subpixels does not overlap with the first color filter pattern 1140a. Due to the size restrictions between the second and third color filter patterns 1140b and 1140c of adjacent second and third color subpixels, the first color filter pattern 1140a does not overlap with this center line L4. Of course, the disclosed embodiments are not limited to this. For example, when the size between the second and third color filter patterns 1140b and 1140c of adjacent second and third color subpixels meets the minimum process requirements for the color filter pattern 1140, the center line L4 connecting the adjacent second and third color subpixels can overlap with the first color filter pattern 1140a, thereby further increasing the area of ​​the first color filter pattern 1140a. In these examples, because the portion of the first color filter pattern 1140a extending between the light-emitting areas of the adjacent second and third color sub-pixels is located on one side of the line L4 connecting the centers of the light-emitting areas of these two sub-pixels, given a specific level of processing precision for the first color filter pattern 1140a, the first color filter pattern 1140a can cover a larger area without affecting adjacent sub-pixels. For example, the space between the light-emitting areas of the adjacent second and third color sub-pixels and passing through the line L4 connecting their centers is the narrowest. At this location, even if the first color filter pattern 1140a is configured to the minimum size (characteristic line width) that can be produced, it is still possible to affect the normal display of the adjacent second and third color sub-pixels. Therefore, the first color filter pattern 1140a can be first formed to extend to the center line L4 connecting the light-emitting areas of the adjacent second color sub-pixels and the third color sub-pixels, and then the end of the first color filter pattern 1140a at this position can be cut off so that the first color filter pattern 1140a and the center line L4 do not overlap, thereby allowing the first color filter pattern 1140a to cover a larger area without affecting the adjacent sub-pixels. Of course, the first color filter pattern 1140a can also be directly formed so that the first color filter pattern 1140a and the center line L4 do not overlap, thereby allowing the first color filter pattern 1140a to cover a larger area without affecting the adjacent sub-pixels.

[0076] In some examples, as shown in Figures 1A and 2, within a subpixel row group Gr, the first color filter pattern 1140a of the first color subpixels in the middle first subpixel row Gr11 extends between the light-emitting areas of adjacent second color subpixels in the adjacent second subpixel row Gr12. For example, the adjacent second color subpixels can be adjacent along the first direction X or along the second direction Y. This can maximize the area of ​​the first color filter pattern 1140a.

[0077] In some examples, as shown in Figures 1A and 2, in the overlapping area of ​​the first color filter pattern 1140a and the third color filter pattern 1140c, the first color filter pattern 1140a is located on the side of the second color filter pattern 1140b away from the base substrate 101; in the overlapping area of ​​the first color filter pattern 1140a and the third color filter pattern 1140c, the first color filter pattern 1140a is located on the side of the third color filter pattern 1140c away from the base substrate 101.

[0078] For example, when preparing the color filter pattern 1140, the second color filter pattern 1140b can be applied first, followed by the third color filter pattern 1140c, and finally the first color filter pattern 1140a. For example, the second color filter pattern 1140b is a blue color filter pattern, the second color filter pattern 1140c is a green color filter pattern, and the first color filter pattern 1140a is a red color filter pattern. When the first color filter pattern 1140a is a red color filter pattern, the dark state of the display panel becomes darker, thereby achieving a better display effect in the dark state.

[0079] In some examples, as shown in FIG. 1A and FIG. 2 , the first color sub-pixel may be a red sub-pixel, the second color sub-pixel may be a blue sub-pixel, and the third color sub-pixel may be a green sub-pixel.

[0080] In some examples, as shown in Figures 1A and 2, in the overlapping region of the first color filter pattern 1140a and the second color filter pattern 1140b, the distance between the boundary of the orthographic projection of the first color filter pattern 1140a on the base substrate 101 and the boundary of the orthographic projection of the second color filter pattern 1140b on the base substrate 101 can be 4 μm. Of course, the embodiments of the present disclosure are not limited to this. For example, the distance between the two can also be less than 4 μm, for example, the distance between the two can be less than or equal to 2 μm, thereby preventing the first color filter pattern 1140a from affecting the second color sub-pixel. For example, the distance between the two can also be greater than 4 μm, thereby further increasing the area of ​​the first color filter pattern 1140a.

[0081] In some examples, as shown in Figures 1A and 2, in the overlapping region of the first color filter pattern 1140a and the third color filter pattern 1140c, the distance between the boundary of the orthographic projection of the first color filter pattern 1140a on the base substrate 101 and the boundary of the orthographic projection of the third color filter pattern 1140c on the base substrate 101 can be 4 μm. Of course, the embodiments of the present disclosure are not limited to this. For example, the distance between the two can also be less than 4 μm, for example, the distance between the two can be less than or equal to 2 μm, thereby preventing the first color filter pattern 1140a from affecting the third color sub-pixel. For example, the distance between the two can also be greater than 4 μm, thereby further increasing the area of ​​the first color filter pattern 1140a.

[0082] In some examples, as shown in FIG1A and FIG2 , in the sub-pixel row group Gr, the first color filter pattern 1140a has a boundary that is at least partially similar to that of the second color filter pattern 1140b adjacent to the first color filter pattern 1140a. For example, at least a portion of the boundary of the first color filter pattern 1140a can be parallel to at least a portion of the boundary of the second color filter pattern 1140b adjacent to the first color filter pattern 1140a. As a result, the area of ​​the first color filter pattern 1140a can be maximized along the boundary of the second color filter pattern 1140b.

[0083] In some examples, as shown in FIG1A and FIG2 , in the sub-pixel row group Gr, the area where the first color filter pattern 1140a and the second color filter pattern 1140b overlap each other includes a strip region SR12 extending along the edge of the second color filter pattern 1140b. This can maximize the area of ​​the first color filter pattern 1140a.

[0084] In some examples, as shown in FIG1A and FIG2 , in the sub-pixel row group Gr, the first color filter pattern 1140a has a boundary that is at least partially similar to that of the third color filter pattern 1140c adjacent to the first color filter pattern 1140a. For example, at least a portion of the boundary of the first color filter pattern 1140a can be parallel to at least a portion of the boundary of the third color filter pattern 1140c adjacent to the first color filter pattern 1140a. As a result, the area of ​​the first color filter pattern 1140a can be maximized along the boundary of the third color filter pattern 1140c.

[0085] In some examples, as shown in FIG1A and FIG2 , in the sub-pixel row group Gr, the area where the first color filter pattern 1140a and the third color filter pattern 1140c overlap each other includes a strip region SR13 extending along the edge of the third color filter pattern 1140c. Thus, the area of ​​the first color filter pattern 1140a can be increased to a greater extent.

[0086] In some examples, as shown in FIG1A and FIG2 , the orthographic projections of the second color filter pattern 1140b and the third color filter pattern 1140c on the base substrate 101 are substantially circular. The boundary of the overlapping portion of the first color filter pattern 1140a and the third color filter pattern 1140c facing the center of the third color filter pattern 1140c is an arc, and the boundary of the overlapping portion of the first color filter pattern 1140a and the second color filter pattern 1140b facing the center of the second color filter pattern 1140b is an arc.

[0087] In some examples, as shown in FIG. 1A and FIG. 2 , the planar shape of the first color filter pattern 1140 a is different from the planar shape of the second color filter pattern 1140 b , and the planar shape of the first color filter pattern 1140 a is different from the planar shape of the third color filter pattern 1140 c .

[0088] In some examples, as shown in FIG. 1A and FIG. 2 , the area of ​​the first color filter pattern 1140 a is larger than the area of ​​the second color filter pattern 1140 b , and the area of ​​the first color filter pattern 1140 a is larger than the area of ​​the third color filter pattern 1140 c .

[0089] In some examples, as shown in Figures 1A and 1B, the display panel further includes a black matrix layer 113, which is disposed on a side of the light-emitting device layer away from the base substrate 101. The black matrix layer 113 has a plurality of escape openings 1130, which expose the light-emitting areas of the light-emitting devices of the plurality of sub-pixels in a direction perpendicular to the base substrate 101. The plurality of escape openings 1130 include a plurality of first escape openings 1130a, a plurality of second escape openings 1130b, and a plurality of third escape openings 1130c, corresponding to the plurality of first color sub-pixels, the plurality of second color sub-pixels, and the plurality of third color sub-pixels, respectively. The plurality of first color filter patterns 1140a, the plurality of second color filter patterns 1140b, and the plurality of third color filter patterns 1140, respectively, cover the plurality of first escape openings 1130a, the plurality of second escape openings 1130b, and the plurality of third escape openings 1130c. By providing the black matrix layer 113 , light incident on the display panel can be absorbed, thereby reducing the reflectivity of the display panel to external light and improving the display effect of the display panel.

[0090] In some examples, as shown in Figures 1A and 1B, the minimum distance between the boundary of the orthographic projection of the color filter pattern 1140 on the base substrate 101 and the boundary of the orthographic projection of the avoidance opening 1130 covered by the color filter pattern 1140 on the base substrate 101 is greater than or equal to 4 μm. This allows the color filter pattern 1140 to better cover the avoidance opening 1130, preventing the color filter pattern 1140 from peeling off. For example, the color filter pattern 1140 may include a first color filter pattern 1140a, a second color filter pattern 1140b, and a third color filter pattern 1140c.

[0091] In some examples, as shown in FIG. 1A , the plurality of first avoidance openings 1130 a and the plurality of second avoidance openings 1130 b are alternately arranged along a first direction X parallel to the base substrate 101 , and the plurality of third avoidance openings 1130 c are arranged along the first direction X.

[0092] In some examples, as shown in Figures 1A and 1B, the display panel's driver circuit layer 102 includes multiple light-transmitting areas 1029, and the black matrix layer 113 further includes multiple light-transmitting openings 1131. Each of the multiple light-transmitting openings 1131 is configured to correspond to at least one of the multiple light-transmitting areas 1029 to transmit light within a predetermined angle range relative to the display panel, such as light L required by a photosensitive device provided on the non-display side of the display panel. For example, the photosensitive device may include an infrared sensor, a distance sensor, a fingerprint recognition module, and a brightness adjustment module. The light-transmitting opening 1131 is located between a first avoidance opening 1130a and a second avoidance opening 1130b adjacent to each other in the first direction X.

[0093] In some examples, as shown in FIG. 1A , the light-transmitting opening 1131 is located between two adjacent second avoiding openings 1130 b in the second direction Y.

[0094] For example, as shown in FIG. 1A , the light-transmitting openings 1131 are arranged in an array of multiple rows and columns.

[0095] For example, as shown in FIG1B , the light-transmitting region 1029 of the driving circuit layer 102 includes a light-transmitting insulating material, which includes the light-transmitting insulating materials of the first gate insulating layer 1025 , the second gate insulating layer 1026 , the interlayer insulating layer 1027 , the passivation layer 1028 and other insulating layers.

[0096] In some examples, as shown in FIG1A and FIG1B , the color filter pattern 1140 does not overlap with the light-transmitting opening 1131 in a direction perpendicular to the base substrate 101. This prevents the color filter pattern 1140 from entering the light-transmitting opening 1131 adjacent to the color filter pattern 1140, thereby avoiding affecting the light-transmitting opening 1131. For example, the first color filter pattern 1140a does not overlap with the light-transmitting opening 1131, the second color filter pattern 1140b does not overlap with the light-transmitting opening 1131, and the third color filter pattern 1140c does not overlap with the light-transmitting opening 1131.

[0097] In some examples, as shown in FIG1A and FIG2 , in the subpixel row group Gr, a portion of the first color filter pattern 1140a of the first color subpixel in the middle first subpixel row Gr11 extends between the adjacent light-transmitting opening 1131 and the light-emitting region of the third color subpixel, and this portion of the first color filter pattern 1140a overlaps with the third color filter pattern 1140c of the third color subpixel in the second direction Y. Thus, the area of ​​the first color filter pattern 1140a can be further increased.

[0098] For example, as shown in Figures 1A and 2, in the sub-pixel row group Gr, in the second direction Y, at least part of the first color filter pattern 1140a of the first color sub-pixel in the middle first sub-pixel row Gr11 is located between the adjacent light-transmitting opening 1131 and the light-emitting area of ​​the third color sub-pixel.

[0099] In some examples, as shown in FIG1A and FIG2 , in the subpixel row group Gr, in the second direction Y, the minimum dimension D2 of the portion of the first color filter pattern 1140a of the first color subpixel in the middle first subpixel row Gr11 between the adjacent light-transmitting opening 1131 and the third color subpixel is greater than or equal to 7 μm. This can not only meet the process requirements of the color filter pattern 1140, but also maximize the area of ​​the first color filter pattern 1140a.

[0100] In some examples, as shown in FIG. 1A and FIG. 2 , a minimum distance D3 between a boundary of an orthographic projection of the color filter pattern 1140 on the base substrate 101 and a boundary of an orthographic projection of the light-transmitting opening 1131 on the base substrate 101 is greater than or equal to 1.3 μm.

[0101] In some examples, as shown in Figures 1A and 2, the first color filter pattern 1140a has a boundary that is at least partially similar to the light-transmitting opening 1131 adjacent to the first color filter pattern 1140a. As a result, the first color filter pattern 1140a can better extend to the light-transmitting opening 1131 adjacent to the first color filter pattern 1140a, thereby maximizing the area of ​​the first color filter pattern 1140a.

[0102] 1A and 2 , the boundary of the second color filter pattern 1140b is different from the boundary of the adjacent light-transmitting opening 1131. Thus, the area of ​​the first color filter pattern 1140a can be maximized between the adjacent second color filter pattern 1140b and the light-transmitting opening 1131.

[0103] For example, the boundary of the third color filter pattern 1140c is different from the boundary of the adjacent light-transmitting opening 1131 , thereby increasing the area of ​​the first color filter pattern 1140a between the adjacent third color filter pattern 1140c and the light-transmitting opening 1131 to a greater extent.

[0104] FIG3 is a planar schematic diagram of the stacked layers of the pixel definition layer, touch layer, and black matrix layer of a display panel provided in at least one embodiment of the present disclosure. As shown in FIG1B and FIG3 , the display panel further includes a planarization layer 109 disposed on the side of the drive circuit layer 102 away from the base substrate 101, and a pixel definition layer 108 disposed on the side of the planarization layer 109 away from the base substrate 101. The pixel definition layer 108 includes a plurality of sub-pixel openings 1080 and a plurality of photosensitive openings 1081. The light-emitting device EM includes a first electrode layer 104, a light-emitting material layer 105, and a second electrode layer 106 stacked sequentially in a direction away from the base substrate 101. The first electrode layer 104 is disposed on the side of the planarization layer 109 away from the base substrate 101, and the pixel definition layer 108 is disposed on the side of the first electrode layer 104 away from the base substrate 101. The plurality of sub-pixel openings 1080 expose the first electrode layer 104 of the light-emitting device EM of each sub-pixel, respectively, and define the light-emitting areas of the sub-pixels.

[0105] As shown in FIG1B and FIG3 , for a sub-pixel opening 1080 and a avoidance opening 1130 corresponding to the same sub-pixel, the orthographic projection of the sub-pixel opening 1080 on the substrate 101 is located inside the orthographic projection of the avoidance opening 1130 on the substrate 101. For a photosensitive opening 1081 and a light-transmitting opening 1131 corresponding to the same light-transmitting region 1029, the orthographic projection of the photosensitive opening 1081 on the substrate 101 is located inside the orthographic projection of the light-transmitting opening 1131 on the substrate 101. Of course, the embodiments of the present disclosure are not limited to this. For example, the orthographic projection of the photosensitive opening 1081 on the substrate 101 may also be located outside the orthographic projection of the light-transmitting opening 1131 on the substrate 101, or the orthographic projection and the light-transmitting opening 1131 may overlap.

[0106] In some examples, as shown in FIG3 , the minimum distance between the boundary of the orthographic projection of the photosensitive opening 1081 on the base substrate 101 and the boundary of the orthographic projection of the light-transmitting opening 1131 on the base substrate 101 is greater than or equal to 1 μm. For example, the distance between the two can be 1 μm, 1.1 μm, 1.2 μm, 1.3 μm, 1.5 μm, 1.6 μm, 1.8 μm, or 2 μm.

[0107] For example, the pixel defining layer 108 may be made of a black light-absorbing material, which is beneficial for absorbing external natural light, thereby reducing reflectivity.

[0108] In some examples, as shown in FIG3 , for a sub-pixel opening 1080 and a relief opening 1130 corresponding to the same sub-pixel, the shape of the sub-pixel opening 1080 is substantially the same as the shape of the relief opening 1130. For example, the shape may be substantially circular or elliptical. For example, at least a portion of the boundary of the sub-pixel opening 1080 and at least a portion of the boundary of the relief opening 1130 are substantially parallel.

[0109] 3 , for a light-sensing opening 1081 and a light-transmitting opening 1131 corresponding to the same light-transmitting region 1029, the shape of the light-sensing opening 1081 is substantially the same as the shape of the light-transmitting opening 1131. For example, at least a portion of the boundary of the light-sensing opening 1081 is substantially parallel to at least a portion of the boundary of the light-transmitting opening 1131.

[0110] In some examples, as shown in FIG. 3 , the plurality of sub-pixel openings 1080 include a plurality of first color sub-pixel openings 1080 a corresponding to a plurality of first color sub-pixels, a plurality of second color sub-pixel openings 1080 b corresponding to a plurality of second color sub-pixels, and a plurality of third color sub-pixel openings 1080 c corresponding to a plurality of third color sub-pixels.

[0111] In some examples, as shown in FIG. 3 , the opening area of ​​the second color sub-pixel opening 1080 b is larger than the opening area of ​​the first color sub-pixel opening 1080 a .

[0112] In some examples, as shown in FIG. 3 , the orthographic projections of the second color sub-pixel opening 1080 b and the third color sub-pixel opening 1080 c on the base substrate 101 are substantially circular.

[0113] In some examples, as shown in FIG3 , the orthographic projection of the first color sub-pixel opening 1080a on the substrate 101 is substantially elliptical. For example, the orthographic projection of the first color sub-pixel opening 1080a on the substrate 101 may be a non-standard ellipse. For example, the first color sub-pixel opening 1080a has an ellipse major axis La and an ellipse minor axis Lb, where the ellipse major axis La is the longest line segment that can be obtained by connecting two points on the first color sub-pixel opening 1080a, and the ellipse minor axis Lb is the perpendicular bisector of the ellipse major axis La. For example, the areas of the portions of the first color sub-pixel opening 1080a on either side of the ellipse major axis La are unequal, and the first color sub-pixel opening 1080a is not symmetrical about the ellipse major axis La; for example, the areas of the portions of the first color sub-pixel opening 1080a on either side of the ellipse minor axis Lb are substantially equal, and the first color sub-pixel opening 1080a is substantially symmetrical about the ellipse minor axis Lb.

[0114] In some examples, as shown in FIG3 , the first sub-pixel row includes a first type of first sub-pixel row R11, and the major axis La of the ellipse of the first color sub-pixel opening 1080a in the first type of first sub-pixel row R11 extends approximately along the first direction X. In the first type of first sub-pixel row R10, the two photosensitive openings 1081 adjacent to the first color sub-pixel opening 1080a are symmetrical about the straight line where the minor axis Lb of the ellipse of the first color sub-pixel opening 1080a is located, and the two photosensitive openings 1081 adjacent to the second color sub-pixel opening 1080b are symmetrical about the straight line along the second direction Y and passing through the center of the second color sub-pixel opening 1080b.

[0115] In some examples, as shown in FIG. 3 , in the first sub-pixel row R11 , two photosensitive openings 1081 adjacent to the first color sub-pixel opening 1080 a form a first photosensitive opening group, and the first photosensitive opening group is arranged along the first direction X.

[0116] In some examples, as shown in Figure 3, the first sub-pixel row includes a second first sub-pixel row R12, and the elliptical major axis La of the first color sub-pixel opening 1080a in the second first sub-pixel row R12 extends approximately along the second direction Y, and in the second first sub-pixel row R12, the two photosensitive openings 1081 adjacent to the second color sub-pixel opening 1080b are symmetrical about a straight line along the second direction Y and passing through the center of the second color sub-pixel opening 1080b.

[0117] In some examples, as shown in FIG. 3 , in the second type first subpixel row R12 , two photosensitive openings 1081 spaced adjacent to the second color subpixel opening 1080 b are symmetrical about a line along the second direction Y and passing through the center of the second color subpixel opening 1080 b .

[0118] In some examples, as shown in FIG3 , a maximum dimension D4 of the photosensitive openings 1081 between the sub-pixels in the second type first sub-pixel row R12 in the first direction X is larger than a maximum dimension D5 of the photosensitive openings 1081 between the sub-pixels in the first type first sub-pixel row R11 in the first direction X.

[0119] In some examples, as shown in FIG. 3 , the first type of first sub-pixel rows R11 and the second type of first sub-pixel rows R12 are alternately arranged in the second direction Y.

[0120] Figure 4 is another schematic cross-sectional view of a display panel provided in accordance with at least one embodiment of the present disclosure. As shown in Figures 3 and 4 , the display panel further includes a touch layer 116 disposed on the side of the pixel defining layer 108 facing away from the base substrate 101. Touch layer 116 includes a plurality of touch traces 1160. The orthographic projections of touch traces 1160 on the base substrate 101 are staggered from the orthographic projections of the avoidance openings 1130 and the light-transmitting openings 1131 on the base substrate 101. The plurality of touch traces 1160 are arranged in a cross-sectional, lattice-like structure. This prevents exposure of the touch traces 1160, reduces the display panel's reflectivity to external light, and enhances the display quality of the display panel.

[0121] For example, the touch layer 116 can be any type of touch structure, such as a self-capacitive touch structure or a mutual-capacitive touch structure. For example, both the self-capacitive touch structure and the mutual-capacitive touch structure include at least one conductive layer. The embodiments of the present disclosure do not limit the specific type and structure of the touch layer 116.

[0122] For example, the touch layer 116 may be a metal layer or a transparent conductive layer, and its material may include metal materials such as copper and aluminum, or transparent metal oxides such as ITO and IZO.

[0123] For example, as shown in FIG4 , the touch layer 116 may further include a substrate B on a side close to the base substrate 101 , and the touch layer 116 may be bonded to the encapsulation layer EN via the substrate B. For example, the substrate B may include an inorganic insulating material such as silicon oxide, silicon nitride, or silicon oxynitride, or an organic insulating material such as polyimide.

[0124] For example, as shown in FIG4 , the touch layer 116 may be covered with a protective insulating layer P. The protective insulating layer P may also include an inorganic insulating material such as silicon oxide, silicon nitride, or silicon oxynitride, or an organic insulating material such as polyimide, to protect the touch layer 116. The embodiments of the present disclosure do not specifically limit other structures and materials of the touch layer 116.

[0125] In some examples, as shown in FIG3 , the minimum distance between the boundary of the orthographic projection of the touch trace 1160 on the base substrate 101 and the boundary of the orthographic projection of the light-transmitting opening 1131 on the base substrate 101 is greater than or equal to 1.7 μm, and the minimum distance between the boundary of the orthographic projection of the touch trace 1160 on the base substrate 101 and the boundary of the orthographic projection of the avoidance opening 1130 on the base substrate 101 is greater than or equal to 1.7 μm.

[0126] Figure 5 is a partial plan view of another stack of pixel definition layers, touch layers, and black matrix layers of a display panel provided by at least one embodiment of the present disclosure. As shown in Figures 4 and 5 , in a direction perpendicular to the base substrate 101, the minimum distance between adjacent sub-pixel openings 1080 and photosensitive openings 1081 is h, and touch traces 1160 are disposed between adjacent sub-pixel openings 1080 and photosensitive openings 1081. The distance between the boundary of the avoidance opening 1130 corresponding to the sub-pixel opening 1080 and the boundary of the sub-pixel opening 1080 is a, and the minimum distance between the boundary of the avoidance opening 1130 and the touch trace 1160 is b. Therefore, a first boundary L5 defining the touch trace 1160 can be obtained based on the boundary of the avoidance opening 1130 and the minimum distance b. The minimum distance between the light-transmitting opening 1131 and the touch trace 1160 is c. Therefore, a second boundary L6 defining the touch trace 1160 can be obtained based on the light-transmitting opening 1131 and the minimum distance c. Consequently, the touch trace 1160 between adjacent sub-pixel openings 1080 and light-sensitive openings 1081 is confined within the region shown between the first boundary L5 and the second boundary L6. For example, the minimum distance b and the minimum distance c can be equal. The size of the touch trace 1160 is d, and the distance between the boundary of the light-transmitting opening 1131 corresponding to the photosensitive opening 1081 and the boundary of the photosensitive opening 1081 is e. Then the minimum distance between adjacent sub-pixel openings 1080 and photosensitive openings 1081 is h=a+b+c+d+e.

[0127] For example, by reducing the distance a, the areas of the light-transmitting opening 1131 and the photosensitive opening 1081 can be increased, thereby improving the photosensitivity of the photosensitive device. For example, the minimum line width of the black matrix layer 113 between adjacent sub-pixel openings 1080 and photosensitive openings 1081 can also be increased, thereby improving the process of the black matrix layer 113, and the areas of the light-transmitting opening 1131 and the photosensitive opening 1081 can also be increased, thereby improving the photosensitivity of the photosensitive device.

[0128] In some examples, as shown in Figures 1B and 4, the display panel may further include structures such as a spacer 107 provided on the pixel defining layer 108 and an encapsulation layer EN provided on the light-emitting device EM of the sub-pixel. For example, the spacer 107 may be made of a black light-absorbing material, which is conducive to absorbing natural light from the outside, thereby reducing the reflectivity. For example, the encapsulation layer EN may include multiple sub-encapsulation layers to improve its encapsulation effect. For example, the encapsulation layer EN may be a composite encapsulation layer, including a first inorganic encapsulation layer 110, a second organic encapsulation layer 111 and a third inorganic encapsulation layer 112. For example, the first inorganic encapsulation layer 110 and the second inorganic encapsulation layer 112 may be formed of inorganic materials such as silicon nitride, silicon oxide, and silicon oxynitride, and the first organic encapsulation layer 111 may be formed of organic materials such as polyimide (PI) and epoxy resin. The composite encapsulation layer can form multiple protections for the functional structures on the display panel and has a better encapsulation effect.

[0129] The structure and circuit arrangement of each functional layer of the display panel provided by the embodiment of the present disclosure are described in detail below by using a specific example. In this example, a 7T1C pixel driving circuit is used to drive the light emitting device EM in a sub-pixel.

[0130] For example, FIG6A shows a circuit diagram of a 7T1C pixel circuit. As shown in FIG6A , the pixel circuit includes a driving circuit 122 , a data writing circuit 126 , a compensation circuit 128 , a storage circuit 127 , a first light emitting control circuit 123 , a second light emitting control circuit 124 , and a reset circuit 129 .

[0131] For example, the driving circuit 122 includes a control terminal 131, a first terminal 132, and a second terminal 133, which is configured to control the driving current flowing through the light-emitting device EM, and the control terminal 131 of the driving circuit 122 is connected to the first node N1, the first terminal 132 of the driving circuit 122 is connected to the second node N2, and the second terminal 133 of the driving circuit 122 is connected to the third node N3.

[0132] For example, the data write circuit 126 includes a control end, a first end, and a second end, wherein the control end is configured to receive a first scan signal Ga1, the first end is configured to receive a data signal Vd, and the second end is connected to the first end 132 (second node N2) of the driving circuit 122, and is configured to write the data signal Vd to the first end 132 of the driving circuit 122 in response to the first scan signal Ga1.

[0133] For example, in the data writing stage, the data writing circuit 126 can be turned on in response to the first scanning signal Ga1, so that the data signal Vd can be written to the first end 132 (the second node N2) of the driving circuit 122, and the data signal can be stored in the storage circuit 127, so that in the light-emitting stage, for example, a driving current can be generated according to the data signal to drive the light-emitting device EM to emit light.

[0134] For example, the compensation circuit 128 includes a control end, a first end, and a second end. The control end is configured to receive a second scanning signal Ga2, and the first end and the second end are electrically connected to the control end 131 and the second end 133 of the driving circuit 122, respectively. The compensation circuit 128 is configured to perform threshold compensation on the driving circuit 120 in response to the second scanning signal Ga2.

[0135] For example, the storage circuit 127 is electrically connected to the control terminal 131 and the first voltage terminal VDD of the driving circuit 122, and is configured to store the data signal Vd written by the data writing circuit 126. For example, during the data writing and compensation phase, the compensation circuit 128 can be turned on in response to the second scanning signal Ga2, thereby storing the data signal written by the data writing circuit 126 in the storage circuit 127. For example, during both the data writing and compensation phases, the compensation circuit 128 can electrically connect the control terminal 131 and the second terminal 133 of the driving circuit 122, thereby storing information related to the threshold voltage of the driving circuit 122 in the storage circuit 127. For example, during the light-emitting phase, the stored data signal and threshold voltage can be used to control the driving circuit 122, so that the output of the driving circuit 122 is compensated.

[0136] For example, the first light emission control circuit 123 is connected to the first terminal 132 (the second node N2) of the driving circuit 122 and the first voltage terminal VDD, and is configured to apply the first power supply voltage of the first voltage terminal VDD to the first terminal 132 of the driving circuit 122 in response to the first light emission control signal. For example, as shown in FIG6A , the first light emission control circuit 123 is connected to the first light emission control terminal EM1, the first voltage terminal VDD, and the second node N2.

[0137] For example, the second light emitting control circuit 124 is connected to the second light emitting control terminal EM2, the first terminal 510 of the light emitting device EM and the second terminal 132 of the driving circuit 122, and is configured to apply a driving current to the light emitting device EM in response to a second light emitting control signal.

[0138] For example, in the light-emitting stage, the second light-emitting control circuit 123 is turned on in response to the second light-emitting control signal provided by the second light-emitting control terminal EM2, so that the driving circuit 122 can apply a driving current to the light-emitting device EM through the second light-emitting control circuit 123 to make it emit light; while in the non-light-emitting stage, the second light-emitting control circuit 123 is turned off in response to the second light-emitting control signal, thereby preventing current from flowing through the light-emitting device EM and causing it to emit light, which can improve the contrast of the corresponding display device.

[0139] For another example, during the initialization phase, the second light emitting control circuit 124 may also be turned on in response to the second light emitting control signal, thereby being combined with the reset circuit 129 to perform a reset operation on the driving circuit 122 and the light emitting device EM.

[0140] For example, the second light emitting control signal EM2 may be the same as or different from the first light emitting control signal EM1 . For example, the two may be connected to the same or different signal output terminals.

[0141] For example, the reset circuit 129 is connected to the reset voltage terminal Vinit and the first terminal 134 (fourth node N4) of the light-emitting device EM, and is configured to apply a reset voltage to the first terminal 134 of the light-emitting device EM in response to a reset signal. In other examples, as shown in FIG6A , the reset signal may also be applied to the control terminal 131 of the driver circuit, i.e., the first node N1. For example, the reset signal may be the second scan signal, or may be another signal synchronized with the second scan signal, which is not limited in the embodiments of the present disclosure. For example, as shown in FIG6A , the reset circuit 129 is respectively connected to the first terminal 134 of the light-emitting device EM, the reset voltage terminal Vinit, and the reset control terminal Rst (reset control line). For example, during the initialization phase, the reset circuit 129 may be turned on in response to the reset signal, thereby applying a reset voltage to the first terminal 134 of the light-emitting device EM and the first node N1, thereby resetting the driver circuit 122, the compensation circuit 128, and the light-emitting device EM, eliminating the effects of the previous light-emitting phase.

[0142] For example, the light-emitting device EM includes a first terminal 134 and a second terminal 135. The first terminal 134 of the light-emitting device EM is configured to receive a driving current from the second terminal 133 of the driving circuit 122, and the second terminal 135 of the light-emitting device EM is configured to be connected to the second voltage terminal VSS. For example, as shown in FIG6A , the first terminal 134 of the light-emitting device EM can be connected to the third node N3 via the second light-emitting circuit 124. Embodiments of the present disclosure include but are not limited to this scenario. For example, the light-emitting device EM can be various types of OLEDs, such as top-emitting, bottom-emitting, or double-sided emitting, capable of emitting red, green, blue, or white light. The first electrode layer and the second electrode layer of the OLED serve as the first terminal 134 and the second terminal 135 of the light-emitting device, respectively. The embodiments of the present disclosure are not limited to the specific structure of the light-emitting device.

[0143] It should be noted that in the description of the embodiments of the present disclosure, the first node N1, the second node N2, the third node N3 and the fourth node N4 do not necessarily represent actual components, but represent the junction points of related circuit connections in the circuit diagram.

[0144] It should be noted that in the description of the embodiments of the present disclosure, the symbol Vd can represent both a data signal terminal and a data signal level. Similarly, Ga1 and Ga2 can represent both a first scan signal and a second scan signal, or both a first scan signal terminal and a second scan signal terminal. Rst can represent both a reset control terminal and a reset signal. The symbol Vinit can represent both a reset voltage terminal and a reset voltage. The symbol VDD can represent both a first voltage terminal and a first power supply voltage. The symbol VSS can represent both a second voltage terminal and a second power supply voltage. The following embodiments are the same and will not be described in detail.

[0145] FIG6B is a circuit diagram of a specific implementation example of the pixel circuit shown in FIG6A . As shown in FIG6B , the pixel circuit includes first to seventh transistors T1, T2, T3, T4, T5, T6, and T7, and a storage capacitor Cst. For example, the third transistor T3 is used as a driving transistor, and the other transistors are used as switching transistors.

[0146] For example, as shown in FIG6B , the driving circuit 122 can be implemented as a third transistor T3. The gate of the third transistor T3 serves as a control terminal 131 of the driving circuit 122 and is connected to the first node N1; the first electrode of the third transistor T3 serves as a first terminal 132 of the driving circuit 122 and is connected to the second node N2; and the second electrode of the third transistor T3 serves as a second terminal 133 of the driving circuit 122 and is connected to the third node N3.

[0147] For example, as shown in FIG6B , the data write circuit 126 can be implemented as a fourth transistor T4. The gate of the fourth transistor T4 is connected to the first scan signal line (first scan signal terminal Ga1) to receive the first scan signal, the first electrode of the fourth transistor T4 is connected to the data line (data signal terminal Vd) to receive the data signal, and the second electrode of the fourth transistor T4 is connected to the first terminal 132 (second node N2) of the drive circuit 122. For example, the fourth transistor T4 is a P-type transistor, such as a thin film transistor whose active layer is low-temperature doped polysilicon.

[0148] For example, as shown in FIG6B , the compensation circuit 128 can be implemented as a second transistor T2.

[0149] For example, as shown in Figure 6B, the storage circuit 127 can be implemented as a storage capacitor Cst, which includes a first capacitor electrode C1 and a second capacitor electrode C2. The first capacitor electrode C1 is connected to the first voltage terminal VDD, and the second capacitor electrode C2 is connected to the control terminal 131 of the driving circuit 122.

[0150] For example, as shown in FIG6B , the first light emission control circuit 123 can be implemented as a fifth transistor T5. A gate of the fifth transistor T5 is connected to the first light emission control line (first light emission control terminal EM1) to receive a first light emission control signal, a first electrode of the fifth transistor T5 is connected to the first voltage terminal VDD to receive a first power supply voltage, and a second electrode of the fifth transistor T5 is connected to the first terminal 132 (second node N2) of the driving circuit 122.

[0151] For example, the light-emitting device EM may be specifically implemented as a light-emitting diode (OLED), wherein a first electrode layer (herein, an anode) of the light-emitting device EM is connected to the fourth node N4 and configured to receive a driving current from the second terminal 133 of the driving circuit 122 via the second light-emitting control circuit 124. A second electrode layer (herein, a cathode) of the light-emitting device EM is configured to be connected to a second voltage terminal VSS to receive a second power supply voltage. For example, the second voltage terminal may be grounded, that is, VSS may be 0V.

[0152] For example, the second light emission control circuit 124 can be implemented as a sixth transistor T6. A gate of the sixth transistor T6 is connected to the second light emission control line (the second light emission control terminal EM2) to receive the second light emission control signal, a first electrode of the sixth transistor T6 is connected to the second terminal 133 (the third node N3) of the drive circuit 122, and a second electrode of the sixth transistor T65 is connected to the first terminal 134 (the fourth node N4) of the light emitting device EM.

[0153] For example, the reset circuit 129 may include a first reset circuit and a second reset circuit. The first reset circuit is configured to apply a first reset voltage Vinit1 to the first node N1 in response to a first reset signal Rst1, and the second reset circuit is configured to apply a second reset voltage Vinit2 to the fourth node N4 in response to a second reset signal Rst2.

[0154] It should be noted that the transistors used in the embodiments of the present disclosure may be thin film transistors, field effect transistors, or other switching devices with the same characteristics. The embodiments of the present disclosure are described using thin film transistors as examples. The source and drain of the transistors used here may be symmetrical in structure, so the source and drain may be structurally indistinguishable. In the embodiments of the present disclosure, in order to distinguish the two poles of the transistor other than the gate, one pole is directly described as the first pole and the other pole is directly described as the second pole.

[0155] The following is a detailed description of the layout design of the above pixel driving circuit.

[0156] For example, Figure 7 shows a schematic diagram of a shielding layer of the display panel. The shielding layer 136 is disposed between the base substrate and the thin film transistor to reduce the adverse effects of the base substrate on the thin film transistor. For example, the shielding layer 136 is made of metal.

[0157] For example, FIG8 shows a schematic diagram of a stack of a shielding layer and a first semiconductor layer of the display panel. The first semiconductor layer 137 can be used to form an active layer of a thin film transistor of a plurality of pixel driving circuits of a plurality of sub-pixels.

[0158] For example, a first gate insulating layer is further disposed on the first semiconductor layer 137 , which is not shown in the figures.

[0159] For example, FIG9 shows a schematic diagram of a stack of a shielding layer, a semiconductor layer, and a first gate metal layer of the display panel, where the first gate metal layer is disposed on the first gate insulating layer.

[0160] For example, as shown in Figure 9, the first gate metal layer includes multiple first scan signal lines S1, multiple light emission control lines EMT, and multiple second capacitor electrodes C2 of storage capacitors Cst. For example, the portions where the multiple first scan signal lines S1, the multiple light emission control lines EMT, and the second capacitor electrodes C2 of the multiple storage capacitors Cst overlap with the active layers of the multiple thin film transistors constitute the gates of the multiple thin film transistors.

[0161] For example, a second gate insulating layer is further provided on the first gate metal layer, which is not shown in the figure.

[0162] FIG10 is a schematic diagram showing a stacked layer of a shielding layer, a semiconductor layer, a first gate metal layer, and a second gate metal layer of the display panel, wherein the second gate metal layer is disposed on the second gate insulating layer.

[0163] For example, as shown in Figure 10, the second gate metal layer includes a first capacitor electrode C1 of a storage capacitor Cst and multiple reset voltage lines VNT2. For example, the second scan signal line S2 may include a first sub-scan signal line S21 and a second sub-scan signal line S22, wherein the multiple first sub-scan signal lines S21 may be located in the second gate metal layer. For example, the reset control line RST may include a first sub-reset control line RST1 and a second sub-reset control line RST2, wherein the multiple first sub-reset control lines RST1 may be located in the second gate metal layer. The first capacitor electrode C1 and the second capacitor electrode C2 of the multiple storage capacitors Cst at least partially overlap to form a capacitor.

[0164] For example, an interlayer insulating layer is further provided on the second gate metal layer, which is not shown in the figure.

[0165] For example, Figure 11 shows a schematic diagram of the shielding layer, semiconductor layer, first gate metal layer, second gate metal layer and second semiconductor layer stack of the display panel, where the second semiconductor layer 138 is used to form the active layer of multiple thin film transistors of the pixel driving circuit of multiple sub-pixels.

[0166] For example, a third gate insulating layer is further disposed on the second semiconductor layer 138 , which is not shown in the figures.

[0167] For example, FIG12 shows a schematic diagram of a stack of a shielding layer, a semiconductor layer, a first gate metal layer, a second gate metal layer, a second semiconductor layer and a third gate metal layer of the display panel, where the third gate metal layer is disposed on the third gate insulating layer.

[0168] For example, as shown in FIG. 12 , the third gate metal layer includes a plurality of reset voltage lines VNT1 , a plurality of second sub-reset control lines RST2 , and a plurality of second sub-scanning signal lines S22 .

[0169] For example, a plurality of interlayer insulating layers are further provided on the third gate metal layer. For example, the interlayer insulating layer may be provided with a plurality of via holes for connecting signal lines stacked later.

[0170] For example, a first source-drain metal layer and a planarization layer are also provided on the interlayer insulating layer. Multiple connecting electrodes are provided on the first source-drain metal layer, and multiple vias are provided in the planarization layer for connecting multiple thin film transistors or connecting signal lines superimposed thereon.

[0171] FIG13A is a schematic diagram showing a second source-drain metal layer of the display panel, where the second source-drain metal layer is disposed on the planarization layer. FIG13B is a schematic diagram showing a display panel with the second source-drain metal layer superimposed on the planarization layer.

[0172] As shown in Figures 13A and 13B, the second source and drain metal layer includes multiple power lines VDD and multiple data lines DT. The multiple power lines VDD are electrically connected to multiple columns of sub-pixels one-to-one to provide power supply voltages, and the multiple data lines DT are electrically connected to multiple columns of sub-pixels one-to-one to provide data signals.

[0173] 6A and 6B , a first terminal of the data write circuit 126 is connected to the data line DT to receive the data signal, and a control terminal is connected to the first scan signal line S1 to receive the first scan signal. For example, a control terminal of the compensation circuit 128 is connected to the second scan signal line S2 to receive the second scan signal.

[0174] For example, a multi-layer planarization layer is further provided on the second source / drain metal layer, and the multi-layer planarization layer has a plurality of via holes for connecting with the first electrode layer of the light-emitting device.

[0175] In some examples, as shown in Figures 12 and 13B, the orthographic projections of the multiple light-transmitting regions 1029 on the substrate are respectively located between the orthographic projection of a first scanning signal line S1 on the substrate and the orthographic projection of a second scanning signal line S2 on the substrate that is closest to the first scanning signal line S1.

[0176] For example, as shown in Figures 12 and 13B, in the light-transmitting area 1029, no other conductive structure is arranged between the adjacent first scanning signal line S1 and the second scanning signal line S2. Therefore, the area of ​​the light-transmitting area 1029 can be set larger, thereby increasing the area of ​​the photosensitive opening 1081 and further improving the photosensitivity of the photosensitive device.

[0177] For example, as shown in Figures 12 and 13B , the first scan signal line S1 extends along the first direction X, and the second scan signal line S2 extends along the first direction X. The portions of the first scan signal line S1 and the second scan signal line S2 defining the light-transmitting area 1029 are bent away from each other, forming a yielding pattern. As a result, the area of ​​the light-transmitting area 1029 can be designed to be larger, thereby increasing the area of ​​the photosensitive opening 1081 and further improving the photosensitivity of the photosensitive device.

[0178] In some examples, as shown in Figures 13A and 13B , the orthographic projections of multiple light-transmitting regions 1029 on the substrate are located between the orthographic projections of adjacent data lines DT on the substrate. Within the light-transmitting regions 1029 , no pixel driver circuits are provided between adjacent data lines DT. Figure 13B uses a dotted box to select four pixel driver circuits in a row. As a result, the area of ​​the light-transmitting regions 1029 can be set larger, thereby increasing the area of ​​the photosensitive opening 1081 and, in turn, improving the photosensitivity of the photosensitive device.

[0179] For example, as shown in Figures 13A and 13B , the data lines DT adjacent to the light-transmitting region 1029 extend along the second direction Y. The portions of the adjacent data lines DT defining the light-transmitting region 1029 bend away from each other, forming a yielding pattern. As a result, the area of ​​the light-transmitting region 1029 can be set larger, thereby increasing the area of ​​the photosensitive opening 1081 and, in turn, improving the photosensitivity of the photosensitive device.

[0180] For example, as shown in Figure 13B, the first scanning signal line S1, the second scanning signal line S2 and the adjacent data line DT jointly define multiple light-transmitting areas 1029, and the area surrounded by the first scanning signal line S1, the second scanning signal line S2 and the adjacent data line DT is the multiple light-transmitting areas 1029 of the driving circuit layer 102.

[0181] Figure 14 shows a schematic diagram of the display panel, in which a first electrode layer, a pixel definition layer, and a black matrix layer are sequentially stacked on the drive circuit layer. As shown in Figures 13B and 14, the orthographic projection of the photosensitive opening 1081 on the base substrate is roughly the same as the shape of the light-transmitting area 1029, and the orthographic projection of the photosensitive opening 1081 on the base substrate is located within the orthographic projection of the light-transmitting area 1029 on the base substrate 101. This effectively prevents light leakage from the drive circuit layer and increases the area of ​​the photosensitive opening 1081, thereby increasing the proportion of the photosensitive opening 1081 that occupies the light-transmitting area 1029 and improving the photosensitivity of the photosensitive device located on the non-display side.

[0182] 13B and 14 , the light-sensing opening 1081 has a boundary that is at least partially similar to that of the light-transmitting region 1029. For example, at least a portion of the boundary of the light-sensing opening 1081 is parallel to at least a portion of the boundary of the light-transmitting region 1029.

[0183] In some examples, as shown in Figures 13B and 14, the minimum distance between the edge of the photosensitive opening 1081 close to the first color sub-pixel opening 1080a and the light-transmitting area 1029 is smaller than the minimum distance between the edge of the photosensitive opening 1081 close to the second color sub-pixel opening 1080b and the light-transmitting area 1029.

[0184] In some examples, the base substrate may include a flexible insulating material such as polyimide (PI) or a rigid insulating material such as a glass substrate. For example, in some examples, the base substrate may be a stacked structure in which multiple flexible layers and multiple barrier layers are alternately arranged. In this case, the flexible layer may include polyimide, and the barrier layer may include an inorganic insulating material such as silicon oxide, silicon nitride, or silicon oxynitride. For example, the buffer layer 103 may include an inorganic material such as silicon nitride, silicon oxide, or silicon oxynitride. The active layer 1021 may be made of materials such as polysilicon and metal oxide, the first gate insulating layer 1024 and the second gate insulating layer 1025 may be made of inorganic insulating materials such as silicon oxide, silicon nitride, or silicon oxynitride, the gate 1022 and the first capacitor electrode C1 may be made of metal materials such as copper, aluminum, titanium, and cobalt, for example, they may be formed into a single-layer structure or a multi-layer structure, such as titanium / aluminum / titanium, molybdenum / aluminum / molybdenum, etc. The second capacitor electrode C2 may be made of metal or alloy materials such as copper, aluminum, titanium, and cobalt, and the interlayer insulating layer 1 026 can be made of inorganic insulating materials such as silicon oxide, silicon nitride or silicon oxynitride, the passivation layer 1027 can be made of inorganic insulating materials such as silicon oxide, silicon nitride or silicon oxynitride, the source and drain electrodes 1023 and 1024 can be made of metal materials such as copper, aluminum, titanium, cobalt, etc., for example, they can be formed into a single-layer structure or a multi-layer structure, such as titanium / aluminum / titanium, molybdenum / aluminum / molybdenum, etc. The first electrode layer 104 is, for example, an anode layer, including metal oxides such as ITO, IZO or metals such as Ag, Al, Mo or their alloys. The material of the light-emitting material layer 105 can be an organic light-emitting material. For example, the material of the light-emitting material layer 105 can be a light-emitting material that can emit a certain color of light (such as red light, blue light or green light, etc.) according to requirements. Of course, because the display panel according to the embodiment of the present disclosure also includes a color filter pattern of the corresponding color, the light-emitting material layer 105 can also be a light-emitting material that emits white light. The second electrode layer 106 is, for example, a cathode layer, including metals such as Mg, Ca, Li, or Al, or alloys thereof, or metal oxides such as IZO and ZTO, or organic materials with conductive properties such as PEDOT / PSS (poly 3,4-ethylenedioxythiophene / polystyrene sulfonate). The planarization layer 109, the pixel defining layer 108, and the spacer 107 can be made of organic insulating materials such as polyimide. The protective cover 115 can be a transparent cover such as a glass cover. The embodiments of the present disclosure do not specifically limit the materials of the various functional layers.
