Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] Organic Light Emitting Diodes (OLEDs) are one of the most popular flat-panel display technologies, boasting advantages such as simple manufacturing processes, low cost, high contrast, wide viewing angles, and low power consumption. However, due to the need for thinness and lightness, the touchscreen layer on OLED display products has shifted from being an external film layer to being embedded between the light-emitting units of the OLED display, significantly impacting the light output of the units. Summary of the Invention

[0003] The embodiments of the present application provide a display panel and a display device, which can improve the color shift visual effect level in different directions after the display panel is embedded with a grid electrode layer, thereby optimizing the display performance of the display panel.

[0004] In a first aspect, an embodiment of the present application provides a display panel, comprising: a substrate; a light-emitting layer, arranged on one side of the substrate, the light-emitting layer including sub-pixels, the sub-pixels including a first sub-pixel, a second sub-pixel and a third sub-pixel of different colors, the second sub-pixel being arranged in a virtual quadrilateral, the first sub-pixel and the third sub-pixel being alternately arranged at the four vertices of the virtual quadrilateral; a grid electrode layer, arranged on a side of the light-emitting layer away from the substrate, the grid electrode layer including grid traces and grid openings formed by the intersection of the grid traces, the orthographic projection of the sub-pixel on the substrate being located within the orthographic projection of the grid opening on the substrate, the grid trace being provided with at least one break, the orthographic projection of the break on the substrate being located between the orthographic projection of the first sub-pixel and the third sub-pixel on the substrate.

[0005] The display panel provided by the embodiment of the first aspect of the present application has a break between the grid lines between the first sub-pixel and the third sub-pixel alternately arranged at the four vertices of a virtual quadrilateral. Compared with directly setting the break on the grid lines surrounding each sub-pixel, the distance between the break and the first sub-pixel, the second sub-pixel and the third sub-pixel is further increased, and the setting of the break further reduces the impact of the light output of the first sub-pixel, the second sub-pixel and the third sub-pixel. The position of the break is set between the first sub-pixel and the third sub-pixel, so that the color deviation visual effect level of the first pixel and the third pixel in different directions remains consistent, thereby improving the color deviation visual effect level of the display panel in different directions after the embedded grid electrode, and realizing the optimization of the display performance of the display panel.

[0006] In a second aspect, an embodiment of the present application further provides a display device comprising a display panel as described in any of the preceding items. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0037] It will be apparent to those skilled in the art that various modifications and variations can be made in this application without departing from the spirit or scope of this application. Therefore, this application is intended to cover modifications and variations of this application that fall within the scope of the corresponding claims (technical solutions claimed for protection) and their equivalents. It should be noted that the embodiments provided in the examples of this application can be combined with each other without contradiction.

[0038] Before describing the technical solutions provided by the embodiments of the present application, in order to facilitate understanding of the embodiments of the present application, the present application first specifically describes the problems existing in the related art:

[0039] Figure 1 The diagram shows a minimum repeating unit of sub-pixels and an arrangement structure of grid lines in a display panel shown in the related art.

[0040] See also Figure 1 In the related art, the current manufacturing trend of organic light-emitting diode (OLED) display panels is to shift the touch function from an external plug-in type to a built-in integrated design, that is, the touch layer is directly manufactured on the display panel packaging layer, and the touch signal is transmitted through the intermediate inorganic layer via the touch metal layer, such as the first metal trace layer (TM1) and the second metal trace layer (TM2).

[0041] While this integration solution simplifies the structure, it introduces new optical challenges: Because the TM1 / TM2 metal traces are located directly above the light-emitting units and are opaque, their physical layout directly blocks part of the light-emitting path. To distinguish between the touch transmitter electrode (TX) and the receiver electrode (RX), existing technologies require designing slits in the metal layer—breaks in the metal traces—to electrically isolate adjacent electrode units and distinguish signal connections.

[0042] However, existing slot layouts have significant drawbacks. Specifically, green (G) pixels typically have slots evenly distributed in all four directions, while red (R) and blue (B) pixels only have slots along a single direction, such as vertically or horizontally.

[0043] This asymmetrical design results in a significant imbalance in optical properties across different orientations: the metal interruptions in the slit areas increase light output in those directions, while the continuous metal coverage in the non-slit areas reduces light output. When users observe the screen from different viewing angles, the difference in light intensity between the R / B pixels in the slit and non-slit directions is amplified, contrasting with the uniform light output of the G pixels. This ultimately causes four-way color shift, where screen colors shift with viewing angle, particularly when displaying solid colors, resulting in uneven distribution of red and blue.

[0044] Furthermore, the inventors discovered that the existing solution sets the slit in the central area close to the edge of the light-emitting unit, where the distance between the slit and the light-emitting area is extremely close, further amplifying the interference of metal obstruction on light output.

[0045] Furthermore, the unidirectional slit design of the R / B pixels prevents them from balancing the optical path like the multi-directional slits of the G pixels, ultimately resulting in unbalanced chromaticity deviations across the panel at horizontal, vertical, and oblique viewing angles. This defect is particularly pronounced in pixel arrangements using a windmill or virtual quadrilateral arrangement, as the spatial overlap of pixels of the same color along the slit extension direction further exacerbates the optical asymmetry in specific directions.

[0046] In summary, while integrated touch panel technology has become mainstream, the interference of metal traces and slits on the light-emitting units has yet to be effectively resolved. Existing technologies have uneven slit distribution across the R / B pixels and their proximity to the light-emitting area, creating a core issue that causes four-way color shift.

[0047] In this context, a display panel with an optimized layout structure using a new type of grid wiring is urgently needed. In order to solve the above technical problems, technical considerations and technical concepts, the embodiments of the present application provide a display panel and a display device.

[0048] The following combination Figures 2 to 7 The display panel and the display device provided in the embodiments of the present application are described in detail.

[0049] Figure 2 1 shows an arrangement structure of a minimum repeating unit of a sub-pixel 20 of a light-emitting layer 2 and a grid trace 31 of a grid electrode layer 30 in a display panel 100 provided by an embodiment of the first aspect of the present application. Figure 3 1 shows another arrangement structure of the minimum repeating unit of the sub-pixel 20 of the light-emitting layer 2 and the grid traces 31 of the grid electrode layer 30 in the display panel 100 provided by the embodiment of the first aspect of the present application. Figure 4 1 shows another arrangement structure of the minimum repeating unit of the sub-pixel 20 of the light-emitting layer 2 and the grid traces 31 of the grid electrode layer 30 in the display panel 100 provided by the embodiment of the first aspect of the present application. Figure 5 1 shows another arrangement structure of the minimum repeating unit of the sub-pixel 20 of the light-emitting layer 2 and the grid traces 31 of the grid electrode layer 30 in the display panel 100 provided by the embodiment of the first aspect of the present application. Figure 6 1 shows another arrangement structure of the minimum repeating unit of the sub-pixel 20 of the light-emitting layer 2 and the grid traces 31 of the grid electrode layer 30 in the display panel 100 provided by the embodiment of the first aspect of the present application. Figure 7Another arrangement structure of the minimum repeating unit of the sub-pixel 20 of the light-emitting layer 2 and the grid wiring 31 of the grid electrode layer 30 in the display panel 100 provided by the embodiment of the first aspect of the present application is shown.

[0050] See also Figures 2 to 7 In a first aspect, an embodiment of the present application provides a display panel 100 , including a substrate 10 , a light-emitting layer 2 and a grid electrode layer 30 .

[0051] The light-emitting layer 2 is arranged on one side of the substrate 10, and the light-emitting layer 2 includes sub-pixels 20. The sub-pixels 20 include a first sub-pixel 21, a second sub-pixel 22 and a third sub-pixel 23 of different colors. The second sub-pixel 22 is arranged in a virtual quadrilateral R, and the first sub-pixel 21 and the third sub-pixel 23 are alternately arranged at the four vertices of the virtual quadrilateral R.

[0052] The grid electrode layer 30 is arranged on the side of the light-emitting layer 2 away from the substrate 10. The grid electrode layer 30 includes grid lines 31 and grid openings 32 formed by the intersection of the grid lines 31. The orthographic projection of the sub-pixel on the substrate 10 is located within the orthographic projection of the grid opening 32 on the substrate 10. The grid line 31 is provided with at least one port, and the orthographic projection of the break on the substrate 10 is located between the orthographic projections of the first sub-pixel 21 and the third sub-pixel 23 on the substrate 10.

[0053] The display panel 100 provided by the embodiment of the first aspect of the present application has a break between the grid lines 31 set between the first sub-pixel 21 and the third sub-pixel 23 alternately set at the four vertices of a virtual quadrilateral R. Compared with directly setting the break on the grid lines 31 surrounding each sub-pixel 20, the distance between the break and the first sub-pixel 21, the second sub-pixel 22 and the third sub-pixel 23 is further increased, and the setting of the break further reduces the impact of the light output of the first sub-pixel 21, the second sub-pixel 22 and the third sub-pixel 23. Moreover, the position of the break is set between the first sub-pixel 21 and the third sub-pixel 23, so that the color deviation visual effect level of the first sub-pixel 21 and the third sub-pixel 23 in different directions remains consistent, thereby improving the color deviation visual effect level of the display panel 100 in different directions after the embedded grid electrode, and realizing the optimization of the display performance of the display panel 100.

[0054] The substrate 10 of the display panel 100 serves as a basic supporting layer, and a light-emitting layer 2 is provided on one side of the substrate 10 . The light-emitting layer 2 includes a first sub-pixel 21 , a second sub-pixel 22 and a third sub-pixel 23 of different colors to realize the light-emitting and normal display functions of the display panel 100 .

[0055] The second sub-pixel 22 is located inside a virtual quadrilateral R, and the first sub-pixel 21 and the third sub-pixel 23 are distributed at the four vertices of the virtual quadrilateral R in an alternating arrangement, forming a windmill pixel layout.

[0056] The core of the pinwheel-type pixel arrangement structure is to define the pixel layout through a virtual quadrilateral R. The second sub-pixel 22 is located at the center of the virtual quadrilateral R, while the first sub-pixel 21 and the third sub-pixel 23 are alternately arranged at the four vertices of the virtual quadrilateral R.

[0057] The pinwheel arrangement structure creates technical conditions for the design of the break position through geometric symmetry. The advantage is that the first sub-pixels 21 and the third sub-pixels 23 at the vertex positions are naturally equidistantly spaced, allowing the break of the grid electrode layer 30 to be precisely set in the center area of ​​the gap between adjacent first sub-pixels 21 and third sub-pixels 23.

[0058] Exemplarily, the orthographic projection of the grid trace 31 on the substrate 10 is strictly limited to between the orthographic projections of the first sub-pixel 21 and the third sub-pixel 23 on the substrate 10 , that is, within the transition zone formed by the lines connecting the vertices of the virtual quadrilateral R.

[0059] Compared with the traditional solution of placing the fracture close to the edge of the sub-pixel 20, the fracture design in the display panel 100 provided in the first aspect embodiment of the present application fully utilizes the vertex spacing of the virtual quadrilateral R, so that the average distance between the fracture and the light-emitting area of ​​any sub-pixel 20 is further increased, thereby weakening the interference of light scattering at the edge of the metal fracture on the light output.

[0060] Furthermore, the arrangement pattern of the vertices of the virtual quadrilateral R enables the first sub-pixels 21 and the third sub-pixels 23 to be spatially alternately distributed, providing regular layout sites for the fractures.

[0061] A grid electrode layer 30 is provided on a side of the light-emitting layer 2 away from the substrate 10. The grid electrode layer 30 is composed of intersecting grid lines 31 forming a grid opening 32. The breaks provided between the grid lines 31 are used to divide the electrode patterns of different potentials. The orthographic projection of the break on the substrate 10 is strictly located in the gap area between the orthographic projections of the adjacent first sub-pixel 21 and the third sub-pixel 23 on the substrate 10.

[0062] The position of the break is limited to the projected gap between the first sub-pixel 21 and the third sub-pixel 23 rather than on the grid line 31 surrounding each sub-pixel 20, so that the physical distance from the edge of the break to the light-emitting area of ​​the first sub-pixel 21, the second sub-pixel 22 and the third sub-pixel 23 is further expanded, and by balancing the number of breaks in different directions for the first sub-pixel 21 and the third sub-pixel 23 on the entire display panel 100, the color deviation visual effects in different directions are further maintained consistent, thereby improving display performance.

[0063] Here, “the orthographic projection of the break on the substrate 10 is located between the orthographic projections of the first sub-pixel 21 and the third sub-pixel 23 on the substrate 10” means that the position of the break is limited to the edge between any two adjacent vertices of the four vertices of the virtual quadrilateral R, so that the setting position distance of the break is basically consistent with the spacing between the first sub-pixel 21, the second sub-pixel 22 and the third sub-pixel 23 adjacent to the break, so that the distance between the setting of the break and the first sub-pixel 21, the second sub-pixel 22 and the third sub-pixel 23 is further enlarged, and the influence on the light output of the first sub-pixel 21, the second sub-pixel 22 and the third sub-pixel 23 is further reduced.

[0064] At the same time, the position of the break is limited to the edge between any two adjacent vertices of the four vertices of the virtual quadrilateral R, which can ensure that the position of the break can cover different orientations of the first sub-pixel 21 and the third sub-pixel 23 .

[0065] Exemplarily, the first sub-pixel 21 is on the left, the third sub-pixel 23 is on the right, and the break is set between the first sub-pixel 21 and the third sub-pixel 23. At this time, the break is located on the right side of the first sub-pixel 21 and at the same time on the left side of the third sub-pixel 23.

[0066] Exemplarily, the first sub-pixel 21 is on the right, the third sub-pixel 23 is on the left, and the break is set between the first sub-pixel 21 and the third sub-pixel 23. At this time, the break is located on the left side of the first sub-pixel 21 and at the same time on the right side of the third sub-pixel 23.

[0067] Exemplarily, the first sub-pixel 21 is on the top, the third sub-pixel 23 is on the bottom, and the break is set between the first sub-pixel 21 and the third sub-pixel 23. At this time, the break is located below the first sub-pixel 21 and above the third sub-pixel 23.

[0068] Exemplarily, the first sub-pixel 21 is at the bottom, the third sub-pixel 23 is at the top, and the break is set between the first sub-pixel 21 and the third sub-pixel 23. At this time, the break is located above the first sub-pixel 21 and below the third sub-pixel 23.

[0069] The breaks can be distributed at any of the four corners of the first sub-pixel 21 and the third sub-pixel 23. However, when designing the electrode pattern, it is necessary to ensure that the number of adjacent breaks in the four directions of each first sub-pixel 21 and third sub-pixel 23 remains equal across the entire panel.

[0070] Exemplarily, the numbers of breaks configured at the upper left, upper right, lower left, and lower right positions of the first sub-pixel 21 remain consistent, and the numbers of breaks configured at the corresponding positions of the third sub-pixel 23 also remain consistent.

[0071] The balance in the orientation and number of the cutouts ensures that the light leakage intensity of the first sub-pixel 21 and the third sub-pixel 23 is consistent in all viewing angles, eliminating the optical difference caused by unidirectional cutouts.

[0072] Because the second sub-pixel 22 is located at the center of the virtual quadrilateral R and is not directly adjacent to the cutout, the light emission characteristics of the second sub-pixel 22 are unaffected by changes in the orientation variable. The coordinated cutout design on the full display panel 100 allows the color shifts of the first, second, and third sub-pixels 21, 22, and 23 to converge and remain consistent across horizontal, vertical, and oblique viewing angles, ultimately achieving color uniformity across the entire viewing angle of the display panel 100.

[0073] For example, the first sub-pixel 21 is a red light-emitting sub-pixel, the second sub-pixel 22 is a green light-emitting sub-pixel, and the third sub-pixel 23 is a blue light-emitting sub-pixel. Since the light-emitting lifetimes of the first, second, and third sub-pixels 21, 22, and 23 decrease in descending order, the first sub-pixel 21 has the smallest area, the second sub-pixel 22 has the second largest area, and the third sub-pixel 23 has the largest area. This ensures that the light-emitting lifetimes and light-emitting brightness of the first, second, and third sub-pixels 21, 22, and 23 of different colors are consistent, thus avoiding the problem of premature failure or brightness decay of a single sub-pixel.

[0074] See also Figures 2 to 7 In some embodiments, the fracture includes a first section 31a and a second section 31b that are oppositely arranged, and the fracture further includes a first fracture K1 and a second fracture K2, the first section 31a and the second section 31b of the second fracture K2 are oppositely arranged along the first direction X, the first section 31a and the second section 31b of the first fracture K1 are oppositely arranged along the second direction Y, and the first direction X intersects with the second direction Y.

[0075] In these embodiments, the first break K1 and the second break K2 have different orientations. The first section 31a and the second section 31b of the first break K1 are arranged relative to each other along the second direction Y. Therefore, the first break K1 extends in the first direction X, and the first section 31a and the second section 31b of the second break K2 are arranged relative to each other along the first direction X. Therefore, the second break K2 extends in the second direction Y. The positions and numbers of the first breaks K1 and the second breaks K2 in different directions are further balanced on the entire display panel 100, so that the color deviation visual effect level in all directions of the display panel 100 remains consistent.

[0076] Subsequently, by combining and arranging the first break K1 and the second break K2 , boundaries extending in different directions can be formed between the electrode patterns, thereby achieving division of the electrode patterns into different shapes.

[0077] The refined design of the fractures achieves in-depth optimization of azimuthal color shift by introducing the first fracture K1 and the second fracture K2. The first section 31a and the second section 31b of the first fracture K1 are arranged opposite each other along the second direction Y, resulting in the fracture extending along the first direction X. Conversely, the first section 31a and the second section 31b of the second fracture K2 are arranged opposite each other along the first direction X, resulting in an extension along the second direction Y.

[0078] The orthogonal layout of the first and second cutouts K1, K2, complement each other across the entire panel. By precisely controlling the number and spatial distribution of the first and second cutouts K1, K2, the intensity of light leakage around each subpixel 20 is consistent in all directions. This balancing mechanism directly eliminates optical anisotropy caused by the uniformity of the cutout extension direction, minimizing color shift across horizontal, vertical, and oblique viewing angles.

[0079] At the same time, the combined arrangement of the first and second cutouts K1 and K2 further reshapes the electrode pattern boundaries. Cutouts extending in different directions form segmented cut points on the grid trace 31, electrically isolating adjacent electrode units along different directions, thereby creating a differentiated electrode pattern tailored to the pixel layout. The combined design of the first and second cutouts K1 and K2 not only meets touch signal transmission requirements but also maintains optical balance.

[0080] The balance and combination of the number and position of the first break K1 and the second break K2 will be further described in other embodiments of the first aspect of the present application below.

[0081] Please continue reading Figures 2 to 7 In some embodiments, the grid opening 32 includes at least one closed opening formed by the grid lines 31, the orthographic projection of at least one of the first sub-pixel 21, the second sub-pixel 22, and the third sub-pixel 23 of different colors on the substrate 10 is located within the orthographic projection of the closed opening on the substrate 10, and at least one of the first break K1 and the second break K2 is arranged on the peripheral side of a closed opening.

[0082] In these embodiments, in addition to at least one closed opening being arranged around at least one of the first sub-pixel 21, the second sub-pixel 22 and the third sub-pixel 23, at least one of the first break K1 and the second break K2 is also distributed on the peripheral side of the at least one closed opening to further create a basic peripheral wiring layout environment for the balance and combination of the number and position between the first break K1 and the second break K2.

[0083] Regarding the layout of the closed opening, first break K1, and second break K2, the closed opening enclosed by the grid lines 31 encloses at least one of the sub-pixels 20 within its projection, forming an optical isolation zone. The first break K1 or the second break K2 is positioned around the closed opening, leveraging the geometric stability of the closed opening to provide precise anchoring for the break, preventing it from drifting into the light-sensitive area of ​​the sub-pixel 20. Furthermore, the peripheral lines create a basic topological framework for balancing the break in different orientations, ensuring that balancing operations do not disrupt electrode function. Finally, the physical isolation of the closed opening further reduces stray light interference from the break on the light-emitting area, synergizing with the directional balancing of the break to enhance display uniformity across all viewing angles.

[0084] Please continue reading Figure 4 and Figure 7 In some embodiments, at least one first break K1 and at least one second break K2 are adjacently arranged on the circumferential side of the same closed opening.

[0085] In these embodiments, the fracture is arranged on the peripheral side of the closed opening, and there are two adjacent fractures. The extension directions of the two adjacent fractures must intersect, that is, the two adjacent fractures must be a first fracture K1 and a second fracture K2, so that the extension directions of the two adjacent fractures intersect, and further realize the number and directional balance of fractures in different directions.

[0086] The technical feature is that at least one first break K1 and one second break K2 are adjacently arranged on the periphery of the same closed opening. When the first break K1 and the second break K2 are adjacently arranged on the closed opening frame, their extension directions must intersect.

[0087] At the optical level, the intersecting fractures form a local micro-grid structure, which causes multi-directional scattering of light at the intersections, avoiding the linear light leakage band caused by unidirectional fractures, thereby balancing the light intensity in all directions;

[0088] On the electrical level, the orthogonal fractures cut the grid traces 31 into conductive paths alternating along the first direction X and the second direction Y, naturally dividing the grid traces 31 into diamond-shaped or rectangular electrode units, thereby meeting the transmission requirements of touch signals in directions other than the first direction X and the second direction Y.

[0089] In terms of the balancing mechanism, adjacent orthogonal fractures serve as basic combination units, and array replication can be used to achieve global quantity balance in the entire display panel 100.

[0090] The closed opening serves as a carrier to further strengthen the design. The peripheral wiring of the closed opening provides stable physical support for the adjacent orthogonal fractures, so that the fracture spacing and position are strictly controlled to avoid deviation to the light-emitting sensitive area of ​​the sub-pixel 20.

[0091] See also Figures 2 to 4In some embodiments, the closed opening includes a first closed opening O1, the orthographic projection of the first sub-pixel 21 and / or the third sub-pixel 23 on the substrate 10 is located within the orthographic projection of the first closed opening O1 on the substrate 10, and at least one of the first break K1 and the second break K2 is arranged on the peripheral side of a first closed opening O1.

[0092] In these embodiments, the first closed opening O1 is arranged around the first sub-pixel 21 and / or the third sub-pixel 23, and the first break K1 and the second break K2 located on the peripheral side of the first closed opening O1 are balanced in number by being arranged adjacent to each other in sequence, thereby achieving balance of the breaks in different extension directions and maintaining consistent color deviation visual effect levels in all directions.

[0093] Exemplarily, the orthographic projection of the first closed opening O1 on the substrate 10 covers the first sub-pixel 21 and the third sub-pixel 23, forming an exclusive optical isolation area surrounding the first sub-pixel 21 and the third sub-pixel 23, so as to minimize the interference of the grid wiring 31 on the light emission of the first sub-pixel 21 and the third sub-pixel 23.

[0094] Exemplarily, when the first break K1 and the second break K2 are both arranged on the peripheral side of the first closed opening O1, the first break K1 and the second break K2 achieve forced intersection in the extension direction through adjacent arrangement. The first break K1 extends along the first direction X, and the second break K2 extends along the second direction Y. The first break K1 and the second break K2 are alternately connected on the peripheral side line to form a direction difference of a certain angle.

[0095] This adjacent and intersecting arrangement of the first and second breaks K1, K2, automatically balances the number of breaks in different directions through a spatial constraint mechanism. Multiple groups of "first break K1 + second break K2" combination units are evenly distributed around each first closed opening O1, ensuring that the number of breaks extending along the first direction X and the second direction Y are strictly equal.

[0096] In terms of directional compensation, the intersecting first break K1 and second break K2 form a symmetrical scattering point array around the sub-pixel 20, and the light leakage intensities in the horizontal and vertical directions offset each other, eliminating the color cast problem at a specific viewing angle.

[0097] In terms of position stability, the rigid frame of the first closed opening O1 fixes the distance between the breaks, preventing the breaks from shifting to the light-emitting sensitive areas of the first sub-pixel 21 and the third sub-pixel 23 during the balancing process.

[0098] In terms of global consistency, for example, all first sub-pixels 21 and third sub-pixels 23 are surrounded by the first closed opening O1 and the peripheral fracture pattern is uniformly adjusted, so that the distribution ratio of the first fracture K1 and the second fracture K2 in the entire area of ​​the panel is 1:1, ultimately achieving the same level of color deviation visual effects for the first sub-pixels 21 and the third sub-pixels 23 at all viewing angles.

[0099] See also Figures 5 to 7 In some embodiments, the closed opening further includes a second closed opening O2, the orthographic projection of the second sub-pixel 22 on the substrate 10 is located within the orthographic projection of the second closed opening O2 on the substrate 10, and at least one of the first break K1 and the second break K2 is arranged on the peripheral side of one of the second closed openings O2.

[0100] In these embodiments, the second closed opening O2 is arranged around the second sub-pixel 22, and the first break K1 and the second break K2 located on the peripheral side of the first closed opening O1 are balanced in number by being arranged adjacent to each other in sequence, thereby achieving balance of the breaks in different extension directions and maintaining consistent color shift visual effects in all directions.

[0101] The orthographic projection of the first closed opening O1 on the substrate 10 covers the second sub-pixel 22 , forming an exclusive optical isolation region surrounding the second sub-pixel 22 , thereby minimizing interference of the grid traces 31 on the light emission of the second sub-pixel 22 .

[0102] Exemplarily, when the first break K1 and the second break K2 are both arranged on the peripheral side of the second closed opening O2, the first break K1 and the second break K2 achieve forced intersection in the extension direction through adjacent arrangement. The first break K1 extends along the first direction X, and the second break K2 extends along the second direction Y. The first break K1 and the second break K2 are alternately connected on the peripheral side line to form a direction difference of a certain angle.

[0103] This adjacent and intersecting arrangement of the first and second breaks K1, K2, automatically balances the number of breaks in different directions through a spatial constraint mechanism. Multiple groups of "first break K1 + second break K2" combination units are evenly distributed around each second closed opening O2, ensuring that the number of breaks extending along the first direction X and the second direction Y are strictly equal.

[0104] In terms of directional compensation, the intersecting first break K1 and second break K2 form a symmetrical scattering point array around the sub-pixel 20, and the light leakage intensities in the horizontal and vertical directions offset each other, eliminating the color cast problem at a specific viewing angle.

[0105] In terms of position stability, the rigid frame of the first closed opening O1 fixes the distance between the breaks, preventing the breaks from shifting to the light-emitting sensitive area of ​​the second sub-pixel 22 during the balancing process.

[0106] In terms of global consistency, for example, all second sub-pixels 22 are surrounded by the second closed opening O2 and the peripheral fracture pattern is uniformly adjusted, so that the distribution ratio of the first fracture K1 and the second fracture K2 in the entire area of ​​the panel is 1:1, ultimately achieving a similar color deviation visual effect level of the second sub-pixels 22 at all viewing angles.

Figure 9 The structure of the second boundary B2 between the plurality of sub-pixels 20 of the light-emitting layer 2 and the first electrode pattern 30a and the second electrode pattern 30b of the grid electrode layer 30 in a display panel 100 provided by an embodiment of the first aspect of the present application is shown. Figure 10 The structure of the third boundary B3 between the plurality of sub-pixels 20 of the light-emitting layer 2 and the first electrode pattern 30a and the second electrode pattern 30b of the grid electrode layer 30 in the display panel 100 provided by the embodiment of the first aspect of the present application is shown. Figure 11 The structure of the fourth boundary B4 between the plurality of sub-pixels 20 of the light-emitting layer 2 and the first electrode pattern 30a and the second electrode pattern 30b of the grid electrode layer 30 in a display panel 100 provided by an embodiment of the first aspect of the present application is shown. Figure 12 1 shows the arrangement structure of the first electrode pattern 30a and the second electrode pattern 30b of the grid electrode layer 30 in the display panel 100 provided by the embodiment of the first aspect of the present application. Figure 13 This is another arrangement structure of the first electrode pattern 30 a and the second electrode pattern 30 b of the grid electrode layer 30 in the display panel 100 provided in the embodiment of the first aspect of the present application.

[0108] See also Figures 8 to 13 In some embodiments, the grid electrode layer 30 is a touch electrode layer and includes a first electrode pattern 30 a and a second electrode pattern 30 b . The first electrode pattern 30 a and the second electrode pattern 30 b are insulated by a plurality of breakouts.

[0109] In these embodiments, the continuous setting of the fractures serves as the dividing boundary between the first electrode pattern 30 a and the second electrode pattern 30 b in the grid electrode layer 30 serving as the touch electrode layer, thereby achieving physical separation of the first electrode pattern 30 a and the second electrode pattern 30 b that implement different functions, and preparing for the first electrode pattern 30 a and the second electrode pattern 30 b to be connected to different potentials without interfering with each other.

[0110] Exemplarily, the grid electrode layer 30 can be divided into a plurality of diamond-shaped first electrode patterns 30a and second electrode patterns 30b by utilizing the continuous distribution of the fractures. The first electrode patterns 30a and the second electrode patterns 30b are both prismatic, have consistent sizes, and can be nested with each other, thereby maximizing the area utilization of the display panel 100.

[0111] Exemplarily, the grid electrode layer 30 can be divided into a first electrode pattern 30a in a cross-shaped pattern and a second electrode pattern 30b arranged around the first electrode pattern 30a by utilizing the continuous distribution of the fractures. A dummy electrode pattern is also provided between two adjacent "first electrode pattern 30a + second electrode pattern 30b" combinations. The area ratios of the first electrode pattern 30a and the second electrode pattern 30b per unit area are similar, thereby further enhancing the touch effect of the grid electrode layer 30 serving as a touch electrode layer.

[0112] See also Figure 8 and Figure 9 In some embodiments, a plurality of first breaks K1 are arranged along a first direction X to form a first boundary B1, a plurality of second breaks K2 are arranged along a second direction Y to form a second boundary B2, and the first electrode pattern 30a and the second electrode pattern 30b are separated and insulated by the first boundary B1 and the second boundary B2.

[0113] In these embodiments, the first boundary B1 is formed by arranging a plurality of first breaks K1 along the first direction X to realize the division of the first electrode pattern 30a and the second electrode pattern 30b along the first direction X, and the second boundary B2 is formed by arranging a plurality of second breaks K2 along the second direction Y to realize the division of the first electrode and the second electrode pattern 30b along the second direction Y.

[0114] The first boundary B1 cuts off the conductive path of the mesh trace 31 in the first direction X through the continuous first break K1 , so that the adjacent first electrode patterns 30 a and second electrode patterns 30 b are electrically isolated along the first direction X.

[0115] Similarly, the second boundary B2 cuts off the conductive path in the second direction Y through the continuous second break K2, thereby achieving insulation division of the electrode along the second direction Y.

[0116] The design of the intersecting first boundary B1 and second boundary B2 forms an insulating grid coordinate system within the pixel space. The intersection of the fracture boundaries in the first direction X naturally divides the rectangular first electrode pattern 30a and second electrode pattern 30b. Each first electrode pattern 30a and second electrode pattern 30b corresponds to an electrode block with the minimum sensitivity of the touch function.

[0117] On the electrical level, the first boundary B1 and the second boundary B2 divide the grid electrode layer 30 into a regular array of first electrode patterns 30 a and second electrode patterns 30 b , ensuring efficient transmission of touch signals along the first direction X and the second direction Y while avoiding signal crosstalk.

[0118] On the optical level, the discrete arrangement of the first boundary B1 and the second boundary B2 formed by the fracture replaces the traditional long-distance slits, changing the metal shielding from a continuous strip to a discrete dot matrix, significantly reducing light loss.

[0119] At the same time, the positions of the first boundary B1 and the second boundary B2 are strictly aligned with the vertex line of the virtual quadrilateral R, so that the fracture projection completely avoids the luminous core area of ​​the sub-pixel 20, realizing the electrode function division while achieving deep suppression of azimuthal color shift.

[0120] See also Figure 10 and Figure 11 In some embodiments, a plurality of first breaks K1 and a plurality of second breaks K2 are arranged at intervals along a third direction D1 to form a third boundary B3, and a plurality of first breaks K1 and a plurality of second breaks K2 are arranged at intervals along a fourth direction D2 to form a fourth boundary B4. The third direction D1 intersects with the fourth direction D2, and the first electrode pattern 30a and the second electrode pattern 30b are insulated by the third boundary B3 and the fourth boundary B4.

[0121] In these embodiments, the third boundary B3 and the fourth boundary B4 are formed by a plurality of first break points K1 and second break points K2 arranged at intervals, thereby dividing the first electrode pattern 30 a and the second electrode pattern 30 b along the third direction D1 and the fourth direction D2 .

[0122] See also Figure 12 and Figure 13 For example, the first electrode pattern 30a and the second electrode pattern 30b can be divided into the first boundary B1, the second boundary B2, the third boundary B3 and the fourth boundary B4 formed by the first break K1 and the second break K2. Figure 10 The diamond shape shown, or Figure 11 The cross-shaped structure shown in the figure achieves consistent color deviation visual effects in all directions by balancing the quantitative relationship between the first break K1 and the second break K2 on the entire surface.
