Description

TECHNICAL FIELD

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

[0002] With the development of display technology, the application of organic light-emitting diode (OLED) display technology in display panels is becoming more and more widespread.

[0003] In order to keep a safe distance between the display panel and the evaporation mask, a support block (SPC) needs to be arranged on the surface of the pixel defining layer, but the introduction of the support block causes a large viewing angle color shift problem when the display panel emits white light. SUMMARY

[0004] The present application provides a display panel and a display device to alleviate the large viewing angle color shift problem of the display panel when emitting white light and improve the display effect of the display panel.

[0005] According to an aspect of the present application, a display panel is provided, comprising:

[0006] a substrate;

[0007] a pixel defining layer located on one side of the substrate, a plurality of sub-pixel openings being arranged in the pixel defining layer;

[0008] a support block, the support block being located on the surface of the pixel defining layer;

[0009] Each adjacent four support blocks form a first rhombus unit, the four sub-pixel openings adjacent to the four support blocks forming the first rhombus unit are of the same color, and two sub-pixel openings in the first direction are located outside the first rhombus unit, and two sub-pixel openings in the second direction are located inside the first rhombus unit.

[0010] In the technical solution, each four adjacent support blocks form a first rhombus unit, four sub-pixel openings adjacent to the four support blocks of the first rhombus unit are of the same color, and two sub-pixel openings in the first direction are located outside the first rhombus unit, and two sub-pixel openings in the second direction are located inside the first rhombus unit, so that the support blocks of the first rhombus unit are distributed in the same position relative to the four sub-pixel openings of the same color adjacent thereto. Therefore, in different directions, the support blocks of the first rhombus array have the same shielding effect on the light of each sub-pixel of the four sub-pixel openings of the same color adjacent thereto. Further, the support blocks have the same shielding effect on the light of the sub-pixels of the sub-pixel openings of different colors in the display panel, which reduces or even eliminates the large-viewing-angle color deviation problem of the display panel. When each sub-pixel of the sub-pixel openings of different colors emits white light, the above technical solution can reduce or even eliminate the large-viewing-angle color deviation problem of the display panel when the display panel emits white light, and improve the display effect of the display panel.

[0011] Optionally, the sub-pixel openings include first color sub-pixel openings, second color sub-pixel openings, and third color sub-pixel openings.

[0012] The support blocks are located at the intersection of four adjacent sub-pixel openings including three colors.

[0013] The sub-pixel openings in the same row in the second direction are of the same color.

[0014] Preferably, the first color is blue, the second color is red, and the third color is green.

[0015] The technical solution reduces the distance between the support blocks and the adjacent sub-pixel openings, ensures that the support blocks do not affect the normal display of the sub-pixels in the adjacent sub-pixel openings, and makes the size and density of the sub-pixel openings comparable to those of conventional products. On the other hand, the arrangement of the support blocks can achieve the function of the mask used in the evaporation process.

[0016] Optionally, in the first direction, the support blocks are located between two sub-pixel openings of different colors.

[0017] In the second direction, the support blocks are located between two sub-pixel openings of the same color.

[0018] The support blocks include a first support block, a second support block, and a third support block.

[0019] In the second direction, the first support block is located between two second color sub-pixel openings.

[0020] In the second direction, the second support block is located between two first color sub-pixel openings.

[0021] The third support block is located between two third color sub-pixel openings in the second direction.

[0022] The technical solution further limits the color distribution of the sub-pixel openings on both sides of one support block of the first rhombus unit in the first direction and the color distribution of the sub-pixel openings on both sides of one support block in the second direction, so that the position distribution of the support block relative to the three color sub-pixel openings is the same, and therefore the blocking of the light of the three color sub-pixels of the three color sub-pixel openings by the support block is the same in different directions, thereby weakening or even eliminating the large-viewing-angle color deviation problem existing when the display panel emits white light.

[0023] Optionally, in the first direction, the first support block, the third support block, and the second support block are arranged in a periodic alternating order.

[0024] In the first direction, three rows of sub-pixel openings are arranged between two adjacent support blocks.

[0025] The technical solution further limits the arrangement rule of the three types of support blocks in the first direction, so that the position distribution of the support block relative to the three color sub-pixel openings is the same, and therefore the blocking of the light of the three color sub-pixels of the three color sub-pixel openings by the support block is the same in different directions, thereby weakening or even eliminating the large-viewing-angle color deviation problem existing when the display panel emits white light.

[0026] Optionally, the support blocks in the same row in the second direction are of the same type.

[0027] In the second direction, three rows of sub-pixel openings are arranged between two adjacent support blocks.

[0028] The technical solution further limits the arrangement rule of the support blocks in the same row in the second direction, so that the position distribution of the support block relative to the three color sub-pixel openings is the same, and therefore the blocking of the light of the three color sub-pixels of the three color sub-pixel openings by the support block is the same in different directions, thereby weakening or even eliminating the large-viewing-angle color deviation problem existing when the display panel emits white light.

[0029] Optionally, every four adjacent support blocks form a second rhombus unit, four sub-pixel openings adjacent to the four support blocks forming the second rhombus unit include three colors, and the four sub-pixel openings are all located in the second rhombus unit, wherein the colors of the two sub-pixel openings in the first direction are different, and the colors of the two sub-pixel openings in the second direction are the same.

[0030] The technical scheme further limits the relative positions of the four adjacent sub-pixel openings including three colors in the second rhombus unit in the first direction and the second direction with the support block, so that the position distribution of the support block relative to the three color sub-pixel openings is the same, and therefore the blocking of the light rays of the three color sub-pixels of the three color sub-pixel openings by the support block in different directions is the same, thereby weakening or even eliminating the large-viewing-angle color shift problem of the display panel.

[0031] Optionally, the second rhombus unit includes a first repeated rhombus unit, a second repeated rhombus unit, and a third repeated rhombus unit.

[0032] In the second direction, the two sub-pixel openings in the second direction in the first repeated rhombus unit are second color sub-pixel openings; in the first direction, the two sub-pixel openings in the first repeated rhombus unit are a first color sub-pixel opening and a third color sub-pixel opening, respectively.

[0033] In the second direction, the two sub-pixel openings in the second direction in the second repeated rhombus unit are first color sub-pixel openings; in the first direction, the two sub-pixel openings in the second repeated rhombus unit are a third color sub-pixel opening and a second color sub-pixel opening, respectively.

[0034] In the second direction, the two sub-pixel openings in the second direction in the third repeated rhombus unit are third color sub-pixel openings; in the first direction, the two sub-pixel openings in the third repeated rhombus unit are a second color sub-pixel opening and a first color sub-pixel opening, respectively.

[0035] In the first direction, the third color sub-pixel opening in the first repeated rhombus unit and the second color sub-pixel opening in the third repeated rhombus unit share a second support block, the third color sub-pixel opening in the second repeated rhombus unit and the first color sub-pixel opening in the third repeated rhombus unit share a first support block, and the first color sub-pixel opening in the first repeated rhombus unit and the second color sub-pixel opening in the second repeated rhombus unit share a third support block.

[0036] The technical scheme further limits the color distribution of the two sub-pixel openings in the second direction in the sub-pixel openings in the second rhombus unit, so that the position distribution of the support block relative to the three color sub-pixel openings is the same, and therefore the blocking of the light rays of the three color sub-pixels of the three color sub-pixel openings by the support block in different directions is the same, thereby weakening or even eliminating the large-viewing-angle color shift problem of the display panel.

[0037] Optionally, in the first direction, the first repeated rhombus unit, the third repeated rhombus unit, and the second repeated rhombus unit are arranged in order and periodically alternately.

[0038] The technical solution further limits the distribution of the second rhombus units in the first direction, so that the position distribution of the support blocks relative to the three-color sub-pixel openings is the same. Therefore, in different directions, the blocking of the light of the three-color sub-pixels of the three-color sub-pixel openings by the support blocks is the same, thereby weakening or even eliminating the large-viewing-angle color shift problem of the display panel.

[0039] Optionally, the second rhombus units in the same row in the second direction are the same.

[0040] The technical solution further limits the distribution of the second rhombus units in the second direction, so that the position distribution of the support blocks relative to the three-color sub-pixel openings is the same. Therefore, in different directions, the blocking of the light of the three-color sub-pixels of the three-color sub-pixel openings by the support blocks is the same, thereby weakening or even eliminating the large-viewing-angle color shift problem of the display panel.

[0041] According to another aspect of the present application, a display device is provided, which comprises the display panel of any of the embodiments of the present application.

[0042] The technical solution has the beneficial effects described in any of the above embodiments.

[0043] The technical solution provided in the embodiment has the following beneficial effects. Each of the four support blocks adjacent to each other constitutes a first rhombus unit. The four sub-pixel openings adjacent to the four support blocks constituting the first rhombus unit are of the same color, and the two sub-pixel openings in the first direction are located outside the first rhombus unit, and the two sub-pixel openings in the second direction are located inside the first rhombus unit. Therefore, the position distribution of the support blocks of the first rhombus unit relative to the four sub-pixel openings of the same color adjacent thereto is the same. Therefore, in different directions, the blocking of the light of the sub-pixels of the four sub-pixel openings of the same color adjacent to each other by the support blocks of the first rhombus array is the same. Therefore, in the display panel, the blocking of the light of the sub-pixels of the sub-pixel openings of different colors by the support blocks is the same, thereby weakening or even eliminating the large-viewing-angle color shift problem of the display panel. When each of the sub-pixels of the sub-pixel openings of different colors emits white light, the above technical solution can weaken or even eliminate the large-viewing-angle color shift problem of the display panel when emitting white light, thereby improving the display effect of the display panel.

[0057] In the following, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application, so that those skilled in the art can better understand the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present application.

[0058] It should be noted that the terms "first", "second" and the like in the description and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not necessarily have to include only those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0059] As described in the above background, the introduction of the support block on the surface of the pixel defining layer causes the large viewing angle color shift problem when the display panel emits white light. Figure 1 is a structural schematic diagram of a display panel provided by the prior art. Figure 2 is a sectional view of a display panel provided by the prior art. Referring to Figure 2 , the display panel includes a substrate 10, a pixel defining layer 20, the pixel defining layer 20 is located on one side of the substrate 10, a sub-pixel opening 21 is arranged in the pixel defining layer 20, and a support block 30 is arranged on the surface of the pixel defining layer 20. A sub-pixel, i.e. a light emitting unit 60, is arranged in each sub-pixel opening 21. The inventors have found through careful research that the introduction of the support block 30 on the surface of the pixel defining layer 20 causes differences in the shielding of light emitted by different color sub-pixels of the display panel, thereby causing a large viewing angle color shift problem when the display panel emits white light. Therefore, the inventors arrange a support block 30 on the same side of a part of the second color sub-pixel openings 210. Referring to Figure 3 , the support block 30 is located on the right side of the second color sub-pixel openings 210. Referring to Figure 4 , the support block 30 is located on the left side of the first color sub-pixel openings 211. Referring to Figure 5 , the support block 30 is located in the middle of the two third color sub-pixel openings 212. Referring to Figures 3-5Since the relative positions of the support blocks 30 relative to the second color sub-pixel openings 210, the first color sub-pixel openings 211 and the third color sub-pixel openings 212 are different. In the OX1 direction, the OX2 direction, the OY1 direction and the OY2 direction, the blocking of the light rays of each sub-pixel of the second color sub-pixel openings 210, the first color sub-pixel openings 211 and the third color sub-pixel openings 212 by the support blocks 30 is different, thereby causing the standard white light in the normal view to still have color deviation problems at a large viewing angle, affecting the display effect and product performance. Therefore, the embodiment of the present application provides the following technical scheme:

[0060] Figure 6 is a structural schematic diagram of a display panel provided by the embodiment of the present application. Referring to Figure 6 and Figure 2 , the display panel comprises: a substrate 10; a pixel definition layer 20 located on one side of the substrate 10, the pixel definition layer 20 being provided with a plurality of sub-pixel openings 21; and support blocks 30 located on the surface of the pixel definition layer 20; referring to Figures 7-9 , each adjacent four support blocks 30 form a first rhombus unit S0, the four sub-pixel openings 21 adjacent to the four support blocks 30 forming the first rhombus unit S0 are the same color, and two sub-pixel openings 21 in the first direction are located outside the first rhombus unit S0, and two sub-pixel openings 21 in the second direction are located inside the first rhombus unit S0.

[0061] Optionally, the first direction and the second direction are arranged perpendicularly. In the embodiment, the first direction is, for example, a direction parallel to OX1, and the second direction is, for example, a direction parallel to OY1. The sub-pixel openings 21 are provided with sub-pixels, i.e., light emitting units 60, and the sub-pixels comprise a stack of an anode 61, an organic light emitting layer 62 and a cathode 63. The anode 61 and the cathode 63 are connected to an electrical signal, a large number of carriers are generated in the organic light emitting layer 62, and light is emitted by recombination of the carriers. It should be noted that the substrate 10 and the pixel definition layer 20 further comprise an array layer 40 and a planarization layer 50, the array layer 40 is provided with a driving circuit composed of a thin film transistor, the source or drain of the thin film transistor is electrically connected to the anode 61 of the sub-pixel 60 in the sub-pixel opening 21, and the driving signal is provided for the sub-pixel 60.

[0062] Referring to Figure 6 , the sub-pixel openings 21 comprise second color sub-pixel openings 210, first color sub-pixel openings 211 and third color sub-pixel openings 212. Referring to Figure 6 and Figure 7Each of the four support blocks 30 adjacent to each other constitutes a first rhombic unit S0, and the four support blocks 30 constituting the first rhombic unit S0 are arranged adjacent to four first color sub-pixel openings 211, and two first color sub-pixel openings 211 in the first direction are located outside the first rhombic unit S0, and two first color sub-pixel openings 211 in the second direction are located inside the first rhombic unit S0.

[0063] Referring to Figure 6 and Figure 8 Each of the four support blocks 30 adjacent to each other constitutes a first rhombic unit S0, and the four support blocks 30 constituting the first rhombic unit S0 are arranged adjacent to four first color sub-pixel openings 211, and two first color sub-pixel openings 211 in the first direction are located outside the first rhombic unit S0, and two first color sub-pixel openings 211 in the second direction are located inside the first rhombic unit S0.

[0064] Referring to Figure 6 and Figure 9 Each of the four support blocks 30 adjacent to each other constitutes a first rhombic unit S0, and the four support blocks 30 constituting the first rhombic unit S0 are arranged adjacent to four third color sub-pixel openings 212, and two third color sub-pixel openings 212 in the first direction are located outside the first rhombic unit S0, and two third color sub-pixel openings 212 in the second direction are located inside the first rhombic unit S0.

[0065] Referring to Figures 7-9 The positions of the support blocks 30 constituting the first rhombic unit S0 relative to the four adjacent second color sub-pixel openings 210, the four adjacent first color sub-pixel openings 211 and the four adjacent third color sub-pixel openings 212 are the same, so in the OX1 direction, the OX2 direction, the OY1 direction and the OY2 direction, the support blocks 30 have the same blocking effect on the light rays of each sub-pixel of the second color sub-pixel openings 210, the first color sub-pixel openings 211 and the third color sub-pixel openings 212, thereby weakening or even eliminating the large viewing angle color shift problem when the display panel emits white light.

[0066] The technical scheme provided by the embodiment is characterized in that each four adjacent support blocks form a first rhombus unit, four sub-pixel openings adjacent to the four support blocks forming the first rhombus unit are of the same color, two sub-pixel openings in the first direction are located outside the first rhombus unit, and two sub-pixel openings in the second direction are located inside the first rhombus unit, so that the support blocks of the first rhombus unit are distributed in the same position relative to the four sub-pixel openings of the same color adjacent to the support blocks. Therefore, in different directions, the support blocks of the first rhombus array have the same shielding effect on the light of each sub-pixel of the four sub-pixel openings of the same color adjacent to the support blocks. Further, in the display panel, the support blocks have the same shielding effect on the light of the sub-pixels of the sub-pixel openings of different colors, thereby weakening or even eliminating the large-viewing-angle color difference problem of the display panel. When each sub-pixel of the sub-pixel openings of different colors emits white light, the above technical scheme can weaken or even eliminate the large-viewing-angle color difference problem of the display panel when the display panel emits white light, thereby improving the display effect of the display panel.

[0067] Optionally, referring to Figure 6 , the sub-pixel openings 21 include a second-color sub-pixel opening 210, a first-color sub-pixel opening 211, and a third-color sub-pixel opening 212; and the support block 30 is located at the intersection of the four adjacent sub-pixel openings 21 of three colors. Preferably, the first color is blue, the second color is red, and the third color is green.

[0068] Specifically, the second-color sub-pixel is arranged in the second-color sub-pixel opening 210. The first-color sub-pixel is arranged in the first-color sub-pixel opening 211. The third-color sub-pixel is arranged in the third-color sub-pixel opening 212. When the first color is blue, the second color is red, and the third color is green, the three primary colors emitted by the blue sub-pixel, the red sub-pixel, and the green sub-pixel can be combined to form white light. Since the support block 30 is located at the intersection of the four adjacent sub-pixel openings 21 of three colors, on the one hand, the distance between the support block 30 and the adjacent sub-pixel openings 21 is reduced, so that the support block 30 does not affect the normal display of the sub-pixels in the adjacent sub-pixel openings 21, and the size and density of the sub-pixel openings 21 are comparable to those of conventional products; on the other hand, the support block 30 can play the role of a mask used in the evaporation process.

[0069] Optionally, in the first direction, the support block is located between two sub-pixel openings of different colors; in the second direction, the support block is located between two sub-pixel openings of the same color; the support block includes a first support block, a second support block, and a third support block; in the second direction, the first support block is located between two second-color sub-pixel openings; in the second direction, the second support block is located between two first-color sub-pixel openings; and in the second direction, the third support block is located between two third-color sub-pixel openings.

[0070] For example, referring to Figure 6 The support blocks 30 include a first support block A, a second support block B, and a third support block C. In the first direction, the first support block A, the second support block B, and the third support block C are all located between two different color sub-pixel openings 21. In the second direction, the first support block A, the second support block B, and the third support block C are all located between two sub-pixel openings 21 of the same color. In the second direction, the first support block A is located between two second color sub-pixel openings 210; in the second direction, the second support block B is located between two first color sub-pixel openings 211; and in the second direction, the third support block C is located between two third color sub-pixel openings 212. For example, referring to Figure 7 The above technical solution makes each adjacent first support block A, second support block B, third support block C, and first support block A form a first rhombus unit S0, and the four support blocks 30 constituting the first rhombus unit S0 are arranged adjacent to four second color sub-pixel openings 210; for example, referring to Figure 8 The above technical solution makes each adjacent first support block A, second support block B, third support block C, and second support block B form a first rhombus unit S0, and the four support blocks 30 constituting the first rhombus unit S0 are arranged adjacent to four first color sub-pixel openings 211; for example, referring to Figure 9 The above technical solution makes each adjacent first support block A, second support block B, third support block C, and third support block C form a first rhombus unit S0, and the four support blocks 30 constituting the first rhombus unit S0 are arranged adjacent to four third color sub-pixel openings 212.

[0071] Specifically, the above technical solution further limits the color distribution of the sub-pixel openings 21 on both sides of one support block 30 of the first rhombus unit S0 in the first direction, and the color distribution of the sub-pixel openings 21 on both sides of one support block 30 in the second direction, so that the position distribution of the support block 30 relative to the three color sub-pixel openings 21 is the same, and therefore the blocking of the light rays of the three color sub-pixels of the three color sub-pixel openings 21 by the support block 30 is the same in different directions, thereby reducing or even eliminating the large viewing angle color deviation problem when the display panel emits white light.

[0072] Optionally, in the first direction, the first support block, the third support block, and the second support block are arranged in a periodic sequence alternately; and in the first direction, three rows of sub-pixel openings are arranged between two adjacent support blocks.

[0073] For example, referring to Figure 6 The first support block A, the third support block C, and the second support block B are arranged in a periodic sequence alternately; and in the first direction, three rows of sub-pixel openings 21 are arranged between two adjacent support blocks 30.

[0074] Specifically, the technical solution is further limited to the arrangement rule of the three types of support blocks 30 in the first direction, so that the position distribution of the support blocks 30 relative to the three-color sub-pixel openings 21 is the same, and thus the blocking of the light of the three-color sub-pixels of the three-color sub-pixel openings 21 by the support blocks 30 is the same in different directions, thereby weakening or even eliminating the large-viewing-angle color deviation problem of the display panel when emitting white light.

[0075] Optionally, the support blocks located in the same row in the second direction are the same type of support blocks; and three rows of sub-pixel openings are arranged between the two adjacent support blocks in the second direction.

[0076] For example, referring to Figure 6 , the support blocks 30 located in the same row in the second direction are the same type of support blocks; and three rows of sub-pixel openings 21 are arranged between the two adjacent support blocks 30 in the second direction.

[0077] Specifically, the technical solution is further limited to the arrangement rule of the support blocks 30 in the same row in the second direction, so that the position distribution of the support blocks 30 relative to the three-color sub-pixel openings 21 is the same, and thus the blocking of the light of the three-color sub-pixels of the three-color sub-pixel openings 21 by the support blocks 30 is the same in different directions, thereby weakening or even eliminating the large-viewing-angle color deviation problem of the display panel when emitting white light.

[0078] Optionally, each four adjacent support blocks also form a second rhombus unit, four sub-pixel openings adjacent to the four support blocks forming the second rhombus unit include three colors, and the four sub-pixel openings are all located in the second rhombus unit, wherein the colors of the two sub-pixel openings in the first direction are different, and the colors of the two sub-pixel openings in the second direction are the same.

[0079] For example, referring to Figure 10 , each four adjacent support blocks 30 also form a second rhombus unit S1, four sub-pixel openings 21 adjacent to the four support blocks 30 forming the second rhombus unit S1 include three colors, and the four sub-pixel openings 21 are all located in the second rhombus unit S1, wherein the colors of the two sub-pixel openings 21 in the first direction are different, and the colors of the two sub-pixel openings 21 in the second direction are the same.

[0085] Specifically, the technical solution is further limited to the distribution rule of the second rhombus unit S1 in the first direction, so that the position distribution of the support block 30 relative to the three-color sub-pixel openings 21 is the same, and therefore the blocking of the light of the three-color sub-pixels of the three-color sub-pixel openings 21 by the support block 30 is the same in different directions, thereby weakening or even eliminating the large-viewing-angle color shift problem of the display panel.

[0086] Optionally, the second rhombus units in the same row in the second direction are the same.

[0087] For example, referring to Figure 10 , the types of the second rhombus units S1 in the same row in the second direction are the same.

[0088] Specifically, the technical solution is further limited to the distribution rule of the second rhombus unit S1 in the first direction, so that the position distribution of the support block 30 relative to the three-color sub-pixel openings 21 is the same, and therefore the blocking of the light of the three-color sub-pixels of the three-color sub-pixel openings 21 by the support block 30 is the same in different directions, thereby weakening or even eliminating the large-viewing-angle color shift problem of the display panel.
