[0018] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific embodiments of the present application will be described in detail in conjunction with the accompanying drawings to make the technical solutions and advantages of the present invention clearer.

[0020] Hereinafter, the technical solutions in the embodiments of the present application will be described clearly and completely with reference to the accompanying drawings, but it is clear that the described embodiments are merely some of the embodiments of the present application, and are not all of the embodiments. All other embodiments that a person skilled in the art can obtain without inventive efforts based on the embodiments of the present application belong to the scope of protection of the present application. In addition, it should be understood that the specific embodiments described in this specification are merely for explaining and interpreting the present application, and are not intended to limit the present application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" used generally refer to the upper and lower sides in the actual use or operating state of the device, specifically, the drawing direction in the accompanying drawings. Meanwhile, "inner" and "outer" refer to the contour of the device.

[0021] Based on the above technical problem, the present application discloses the following technical solution.

[0022] Referring to Figures 1 and 2, the present invention provides a display panel, which includes a plurality of first sub-pixels 10, a plurality of second sub-pixels 20, and a plurality of third sub-pixels 30 having different emission colors, wherein two adjacent first sub-pixels 10 form one group, two adjacent second sub-pixels 20 form one group, and two adjacent third sub-pixels 30 form one group, a minimum spacing between the centers of the first sub-pixels 10 of the plurality of groups is a first spacing, a minimum spacing between the centers of the second sub-pixels 20 of the plurality of groups is a second spacing, and a minimum spacing between the centers of the third sub-pixels 30 of the plurality of groups is a third spacing, the first spacing is greater than the second spacing, and the first spacing is greater than the third spacing.

[0023] The present application reduces interference between two adjacent first subpixels 10, thereby improving the problem of color separation caused by light interference, by setting the minimum distance between the centers of two adjacent first subpixels 10 of a display panel to be larger than the minimum distance between the centers of two other types of adjacent pixels of the same color.

[0024] 1 and 2, which are schematic diagrams of two types of arrangements of a plurality of subpixels of a display panel, in which the centers of any two adjacent first subpixels 10 have a plurality of different intervals, where the minimum interval is the first interval. The centers of any two adjacent second subpixels 20 have a plurality of different intervals, where the minimum interval is the second interval. The centers of any two adjacent third subpixels 30 have a plurality of different intervals, where the minimum interval is the third interval. For ease of explanation, in this application, any two adjacent first subpixels 10 are referred to as a group, any two adjacent second subpixels 20 are referred to as a group, and any two adjacent third subpixels 30 are referred to as a group, and the interval between the centers of the first subpixels 10 of the plurality of groups refers to the interval between the centers of the first subpixels 10 of any one group, where the minimum interval is the first interval. Similarly, the center-to-center spacing of the second subpixels 20 in the groups refers to the center-to-center spacing of any one of the second subpixels 20 in the groups, where the minimum spacing is the second spacing, and the center-to-center spacing of the third subpixels 30 in the groups refers to the center-to-center spacing of any one of the third subpixels 30 in the groups, where the minimum spacing is the third spacing.

[0025] By setting the first interval to be larger than the second interval and the first interval to be larger than the third interval, the interference between two adjacent first sub-pixels 10 is reduced, and the color separation problem is improved.

[0026] In this embodiment, the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30 have different colors. For example, the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30 may be any one of a red sub-pixel, a green sub-pixel, and a blue sub-pixel, respectively.

[0027] 3, the display panel includes an array substrate 40 and an anode electrode 131 disposed on the array substrate 40, the array substrate 40 including a plurality of thin film transistors (not shown) arranged in an array, the source-drain layers of the thin film transistors being electrically connected to the anode electrode 131 for supplying driving signals to the anode electrode 131. The array substrate 40 may include a planarization layer 136, the planarization layer 136 being located on a side of the anode electrode 131 farther from the light-emitting surface of the display panel. The display panel further includes a pixel definition layer 137, the pixel definition layer 137 including a plurality of openings, one sub-pixel corresponding to one opening.

[0028] The display panel further includes a hole injection layer 132, a hole transport layer 133, a light emitting material layer 110, an electron transport layer 134, and a cathode 135, which are stacked on the anode electrode 131. The anode electrode 131 is used to provide holes, the hole transport layer 133 is used to transport the holes to the light emitting material layer 110, the cathode 135 is used to provide electrons, and the electron transport layer 134 is used to transport the electrons to the light emitting material layer 110, where the holes and electrons combine to emit light. One pixel corresponds to one anode electrode 131. The cathodes 135 of the display panel may be arranged in series to supply voltage signals to all the pixels.

[0029] The light emitting material layer 110 of the display panel can be prepared by a deposition process or an inkjet printing process. If it is prepared by an inkjet printing process, the use of a photomask can be reduced, and the material cost of the light emitting material layer 110 can also be reduced.

[0030] The display panel may further include a package layer 140 disposed on the cathode 135, and the package layer 140 may be a thin-film package layer. For example, the package layer 140 may include, but is not limited to, a multi-layer structure formed by sequentially stacking an inorganic layer, an organic layer, and an inorganic layer. The organic layer of the package layer 140 has a planarizing effect and can form a flat upper surface. For example, when the number of layers of the light-emitting material layers 110 of the sub-pixels of different colors is different, the organic layer can fill the uneven step and make the surface of the organic layer farther from the array substrate 40 flat, thereby not affecting the surface flatness of the display panel.

[0031] The display panel may further include a cover plate 150 disposed on the package layer 140, and the cover plate 150 may be, but is not limited to, ultra foldable glass (UFG), ultra-thin glass (UTG), colorless polyimide, etc. The cover plate 150 has a certain degree of impact resistance function, can protect the display panel, and prevents the display panel from being damaged by an external force.

[0032] The technical solution of the present application will now be described with reference to specific embodiments.

[0033] As shown in FIG. 1, in this embodiment, at least two groups of two adjacent first sub-pixels 10 have different intervals. As shown in FIG. 1, four adjacent first sub-pixels 10 are divided into two rows and two columns. The two pixels in the first row are grouped as a first group, and the interval between the centers of the first sub-pixels 10 in the first group is L1. The two first sub-pixels 10 in the first column are grouped as a second group, and the interval between the centers of the first sub-pixels 10 in the second group is L2. L1 is not equal to L2. This arrangement allows the intervals between adjacent first sub-pixels 10 to be different, reducing the interference between two adjacent first sub-pixels 10 in multiple directions and improving the color separation problem.

[0034] Similarly, at least two groups of two adjacent second subpixels 20 have different intervals, and / or at least two groups of two adjacent third subpixels 30 have different intervals. That is, by making the intervals between two adjacent subpixels in at least one of the first subpixels 10, the second subpixels 20, and the third subpixels 30 different, the effect of improving the color separation problem is achieved.

[0035] By making the intervals between adjacent first sub-pixels 10, adjacent second sub-pixels 20, and adjacent third sub-pixels 30 different, it is possible to further reduce the interference of light between the sub-pixels and improve the color separation problem. That is, the more the intervals between two adjacent sub-pixels are different, the better the effect of improving color separation.

[0036] As shown in FIG. 1, in this embodiment, the display panel includes a plurality of overlap units 100 arranged along a first direction Y and a second direction X, where the second direction X is perpendicular to the first direction Y, and the overlap unit 100 includes a first sub-overlap unit 103 and a second sub-overlap unit 104. The first sub-overlap unit 103 includes a first sub-pixel 10, a second sub-pixel 20, and a third sub-pixel 30, and a line connecting the centers of the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30 forms a first virtual triangle 101. The second sub-overlap unit 104 includes a first sub-pixel 10, a second sub-pixel 20, and a third sub-pixel 30, and a line connecting the centers of the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30 forms a second virtual triangle 102. Here, the first virtual triangle 101 and the second virtual triangle 102 may be arranged along the first direction Y, but are not limited thereto. The first virtual triangle 101 and the second virtual triangle 102 are point-symmetric, and in the first sub-overlapping unit 103 or the second sub-overlapping unit 104, the line connecting the center of the second sub-pixel 20 and the center of the third sub-pixel is parallel to the first direction Y.

[0037] In the first sub-overlapping unit 103, the centers of the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30 form the vertices of a first virtual triangle 101, and in the second sub-overlapping unit 104, the centers of the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30 form the vertices of a second virtual triangle 102.

[0038] FIG. 1 shows two overlap units 100 arranged along the second direction X. In the same overlap unit 100, the first virtual triangle 101 and the second virtual triangle 102 are point-symmetric, that is, in the same overlap unit 100, the first virtual triangle 101 can overlap the second virtual triangle 102 after rotating 180°. In any one virtual triangle, a line connecting the center of the second sub-pixel 20 and the center of the third sub-pixel 30 is parallel to the first direction Y. By using the above method, the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30 are arranged in a tiled shape, and the first interval is larger than the second interval, and the first interval is larger than the third interval. In addition, since sub-pixel rendering (SPR) is applied to the tiled shape arrangement, a display effect of pixel density (pixel per inch) can be realized.

[0039] In this embodiment, the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30 may be circular, polygonal, etc. When the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30 are polygonal, the polygon may be a regular regular polygon or an irregular polygon, for example, the polygon may be a square, a regular pentagon, a regular hexagon, etc., but is not limited thereto. When the polygon is a regular regular polygon, the sub-pixel has symmetry and the display effect is better.

[0040] As shown in FIG. 2, in this embodiment, the third sub-pixels 30 are polygonal, and the centers of the third sub-pixels 30 are collinear at least in the direction of the first straight line S1.

[0041] The direction of the first straight line S1 can be adaptively adjusted according to the shape of the sub-pixel.

[0042] For example, if the subpixel has a square shape, the first line S1 may be perpendicular to a side of the square. If the subpixel has a circular shape, the first line S1 may be in any direction passing through the center of the circle. If the subpixel has a polygonal shape, the first line S1 may be perpendicular to a side of the polygon.

[0043] Preferably, the first straight line S1 may be perpendicular to the shortest side of the polygon. Since the diffraction is strongest in the direction perpendicular to the shortest side of the polygon, when the first straight line S1 is perpendicular to the shortest side of the polygon, the diffraction effect can be better reduced and the color separation problem can be improved. Preferably, the first straight line S1 is a middle perpendicular to the shortest side of the polygon, and the centers of the third sub-pixels 30 are positioned on the first straight line S1, thereby increasing the symmetry of the arrangement of the sub-pixels and improving the display effect.

[0044] In the direction of the first straight line S1, the centers of the third subpixels 30 of the multiple groups are spaced apart from one another. As shown in Fig. 2, in the direction of the first straight line S1, the center distance between two adjacent third subpixels 30 of one group is D1, and the center distance between two adjacent third subpixels 30 of another group is D2, and the magnitudes of D1 and D2 are different. The direction of the first straight line S1 may be a direction that overlaps with another diagonal line of the first sub overlap unit 103, but the present application is not limited thereto.

[0045] This arrangement reduces the interference of reflected light between the third sub-pixels 30 in the direction of the first straight line S1, thereby improving the problem of color separation caused by the interference of light rays.

[0046] 1, in this embodiment, the second interval is larger than the third interval. By setting the second interval to be larger than the third interval, the first interval, the second interval, and the third interval are not different from each other, so that the interference between any one subpixel of the same color can be mitigated and the color separation problem can be improved.

[0047] In this embodiment, as shown in FIG. 2, the third sub-pixel 30 may be rectangular, and at least one side of the third sub-pixel 30 forms an angle of 45° with the first direction Y.

[0048] As shown in Fig. 3, Fig. 3 is a schematic diagram showing a cross-sectional structure of another display panel of the present application. In this embodiment, the display panel includes light emitting material layers 110 arranged in an array, and the third sub-pixel 30 includes at least two stacked light emitting material layers 110, the number of the light emitting material layers 110 of the third sub-pixel 30 is greater than the number of the light emitting material layers 110 of the first sub-pixel 10, and the number of the light emitting material layers 110 of the third sub-pixel 30 is greater than the number of the light emitting material layers 110 of the second sub-pixel 20.

[0049] In this embodiment, the light emitting material layer 110 of the second subpixel 20 includes a second light emitting material layer 112. The second subpixel 20 includes a hole injection layer 132, a hole transport layer 133, the second light emitting material layer 112, and an electron transport layer 134, which are stacked in order.

[0050] The light emitting material layer 110 of the first subpixel 10 includes a first light emitting material layer 111. The first subpixel 10 includes a hole injection layer 132, a hole transport layer 133, the first light emitting material layer 111, and an electron transport layer 134, which are stacked in this order.

[0051] The light emitting material layer 110 of the third sub-pixel 30 includes a third light emitting material layer 113, which includes a first sub-layer 1131 and a second sub-layer 1132. The first sub-layer 1131 and the second sub-layer 1132 are formed by tandem stacking. This arrangement can improve the light emitting efficiency of the third sub-pixel 30. Specifically, a charge generation layer 122 (Charge Generation Layer, CGL) and a first hole transport layer 123 may be disposed between the first sub-layer 1131 and the second sub-layer 1132, and the charge generation layer 122 may be an N-type charge generation layer N-CGL or a P-type charge generation layer P-CGL, and the first hole transport layer 123 may be a P+HTL layer doped with a P-type material, but is not limited thereto.

[0052] In this embodiment, the third subpixel 30 may include a hole injection layer 132, a hole transport layer 133, a first sublayer 1131, a first electron transport layer 121, a charge generation layer 122, a first hole transport layer 123, a second sublayer 1132, and an electron transport layer 134, which are stacked in order. The above arrangement constitutes a tandem OLED, which can increase the luminous efficiency of the third subpixel 30 and reduce the reflectance of the third subpixel 30. By reducing the reflectance of the third subpixel 30, the interference effect between the third subpixel 30 and the second subpixel 20 or the first subpixel 10 can be destroyed, and the diffraction effect of the third subpixel 30 can be reduced, thereby further improving the color separation problem.

[0053] In some embodiments, the third subpixel 30 further includes an auxiliary functional layer 124, which is disposed between the hole transport layer 133 and the first sublayer 1131. The auxiliary functional layer 124 can be adjusted to achieve a better display effect for the OLED device. For example, the auxiliary functional layer 124 can adjust the hole injection efficiency of the lower layer or block the electrons of the first sublayer 1131.

[0054] Furthermore, in some embodiments, the third subpixel 30 is a blue subpixel. Since the blue subpixel has a lower luminous efficiency than the red and green subpixels, the tandem design for the blue subpixel can not only increase the luminous efficiency of the blue subpixel and make the luminous efficiencies of the three color pixels of the display panel closer to each other, but also reduce the reflectance of the blue subpixel, thereby reducing the interference efficiency between the blue subpixel and other red or green subpixels in one white pixel, and reducing the diffraction effect of the blue subpixel.

[0055] Furthermore, in some embodiments, the number of light-emitting material layers 110 of the third subpixel 30 is two, the number of light-emitting material layers 110 of the first subpixel 10 is one, and the number of light-emitting material layers 110 of the second subpixel 20 is one.

[0056] Preferably, the third subpixel 30 may be a blue subpixel, and at the same time, the second interval is greater than the third interval. At this time, the interval between the centers of the two adjacent blue subpixels is the closest, but the number of the luminescent material layers 110 of the blue subpixel is greater than the number of the luminescent material layers 110 of the other two color pixels, so the reflectance of the anode electrode 131 of the blue subpixel is the lowest. The final effect is that the interference between adjacent blue subpixels is weak. Accordingly, the number of the luminescent material layers 110 of the red subpixels and the green subpixels is less than the number of the luminescent material layers 110 of the blue subpixel, so the reflectance of the anode electrode 131 of the red subpixels and the green subpixels is higher than the reflectance of the anode electrode 131 of the blue subpixel, but the interval between adjacent red subpixels and the interval between adjacent green subpixels are relatively large, so the interference is also weak. With the above arrangement, the number of luminescent layers can be matched to the interval between adjacent pixels, so that the interference can be reduced in two aspects.

[0057] 4, in this embodiment, the display panel includes a first display section 16 and a second display section 17, and the light transmittance of the first display section 16 is greater than that of the second display section 17. The first display section 16 may correspond to a functional component of the display panel, and for example, the functional component may be, but is not limited to, a camera or the like.

[0058] 4, the first display unit 16 and the second display unit 17 are both located within a display area AA of the display panel, and both the first display unit 16 and the second display unit 17 can be used as a display screen. The display panel further includes a non-display area NA located around the display area AA.

[0059] By arranging the camera on the backlight surface side of the display panel and positioning the orthogonal projection of the camera on the display panel on the first display section 16, the light transmittance of the first display section 16 becomes greater than that of the second display section 17, thereby improving the problem of color separation in the camera area and also improving the problem of degradation of image quality caused by diffraction of light rays. Compared to conventional display panels, the first display section 16 of the display panel of the present application has a weaker diffraction effect, so the problem of degradation of image quality caused by diffraction effect can also be improved.

[0060] Furthermore, in all the above embodiments, the first sub-pixel 10 is a green sub-pixel, the second sub-pixel 20 is a red sub-pixel, and the third sub-pixel 30 is a blue sub-pixel. This arrangement can increase the luminous efficiency of the blue sub-pixel and make the luminous efficiency of the three color pixels relatively close to each other. Meanwhile, the third interval of the blue sub-pixels in the direction of the first straight line S1 is minimized to reduce the refractive index of the blue sub-pixels and reduce the interference of the blue sub-pixels in the direction of the first straight line S1. In addition, the intervals of the adjacent blue sub-pixels in the direction of the first straight line S1 are made different, i.e., D1 and D2 are made different, so that the interference of the blue sub-pixels can be further weakened and the color separation problem can be further improved.

[0061] The present application further provides a display terminal, which includes the above-mentioned display panel.

[0062] In this embodiment, the display terminal may be a product or part having a display function, such as a mobile phone, a tablet computer, a television, a display device, a notebook computer, a digital photo frame, or a navigation system.
