[0037] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0038] In the related art, the color filter layer includes color resist blocks of different colors, and its function is to filter white light to orderly form the three primary colors of RGB (red, green, and blue), and realize full-color display through RGB color mixing. Therefore, the color filter layer plays a crucial role in the silicon-based OLED display device.

[0039] Currently, during the exposure process of the color filter layer, due to the influence of the optical edge effect, the edges and corners of the color resist blocks will be deformed and rounded, resulting in a reduction in the size of each side of the color resist blocks, leading to voids at the overlapping positions of the color resist blocks, causing color bleeding and light leakage defects, affecting display uniformity, and reducing the color gamut. At the same time, the voids of the color resist blocks in the color filter layer mainly appear at the corners, there are differences between rows. The gap differences of the color resist blocks within a row are relatively small, but there are some rows with larger voids of the color resist blocks in the row direction, and the voids of the color resist blocks in another row are small, thus resulting in light leakage differences between rows and affecting the display effect.

[0040] In view of this, embodiments of the present application propose a display panel and a display device, aiming to improve the display uniformity of the display device and reduce the light leakage phenomenon of the display device.

[0041] Referring to Figure 1 As shown, a display panel disclosed in an embodiment of the present application includes a substrate 10, a light-emitting layer 20, and a color filter layer 30.

[0042] Specifically, the substrate 10 can be made of single-crystalline silicon material, and various modules included in the driving chip (including a timing control module, a row and column driving circuit, a power management module, etc.) and pixel circuits are integrated on the substrate 10. The pixel circuits can drive corresponding pixel units in the light-emitting layer 20 to emit light, thereby realizing picture display.

[0043] The light-emitting layer 20 can include a plurality of light-emitting devices, and each light-emitting device includes an anode 21, a light-emitting material layer 22, and a cathode 23. Among them, each light-emitting device corresponds to a pixel unit, and the anodes 21 of each light-emitting device are independent of each other, while the cathode 23 can entirely cover the light-emitting material layer 22. The light-emitting material layer 22 includes small molecule organic materials or polymer molecule organic materials, and the light-emitting material layer 22 can also include functional layers such as an electron injection layer, an electron transport layer, a hole injection layer, and a hole transport layer. The anode 21 can be made of materials such as ITO (indium tin oxide), indium zinc oxide (IZO), zinc oxide (ZnO), etc., and the cathode 23 can be made of metal materials such as lithium (Li), aluminum (Al), magnesium (Mg), silver (Ag), etc.

[0044] Referring to Figure 2 As shown, the color filter layer 30 is disposed on a side of the light-emitting layer 20 facing away from the substrate 10. The color filter layer 30 includes a plurality of color resist units 31 arranged along a first direction X, and each color resist unit 31 includes a plurality of color resist blocks 311 arranged along a second direction Y; wherein, the first direction X and the second direction Y intersect with each other; in the embodiment of the present application, the first direction X and the second direction Y are perpendicular to each other. It can be understood that the color resist blocks 311 correspond one-to-one to the light-emitting devices of the light-emitting layer 20, that is, the color resist blocks 311 correspond one-to-one to the pixel units. In this way, the color resist blocks 31 can convert the white light emitted by each pixel unit into other colors (such as red) corresponding to the colors of the color resist blocks 311. At the same time, there is a gap between two adjacent color resist units 31, that is, the orthographic projections of two adjacent color resist units 31 on the substrate 10 do not overlap.

[0045] In the embodiments of the present application, the color filter blocks 311 include a first color, a second color, and a third color. The color filter blocks 311 of the first color can convert white light into the first color, the color filter blocks 311 of the second color can convert white light into the second color, and the color filter blocks 311 of the third color can convert white light into the third color. And in the color filter unit, the color filter blocks 311 are arranged in sequence along the second direction Y in the order of the first color, the second color, and the third color and repeated. Among them, the first color can be red, the second color can be green, and the third color can be blue( Figure 2 in which the color filter blocks 311 of different colors are characterized by different filling shapes).

[0046] In addition, referring to Figure 2 as shown, the orthographic projection shape of the color filter blocks 311 on the substrate 10 may include a circle, a rectangle, a parallelogram, and a hexagon. In the embodiments of the present application, the orthographic projection shape of the color filter blocks 311 on the substrate 10 is a hexagon. And in two adjacent color filter units 31, the color filter blocks 311 are staggered, that is, the color filter blocks 311 in two adjacent color filter units 31 are not aligned. Due to the hexagonal orthographic projection shape of the color filter blocks 311, the staggered arrangement can make the color filter blocks 311 roughly completely fill the light-emitting area of the entire display panel, thereby better reducing the light leakage phenomenon of the display panel.

[0047] Referring to Figure 2 as shown, in the embodiments of the present application, a plurality of color filter units 31 arranged along the first direction X are divided into a plurality of unit groups 301. Each unit group 301 includes a plurality of color filter units 31, and the plurality of color filter units 31 in each unit group 301 are a plurality of color filter units 31 arranged continuously in the first direction X. For example, if each unit group 301 includes three color filter units 31, then the color filter units 31 included in the first unit group 301 in the first direction X are the color filter units of the first row, the color filter units of the second row, and the color filter units of the third row, and the second unit group includes the color filter units of the fourth row, the color filter units of the fifth row, and the color filter units of the sixth row.

[0048] At the same time, in the first direction X, the gap size between any two adjacent unit groups 301 is approximately equal to the first size C1. That is to say, for any two adjacent unit groups 301, the gap size between them is approximately the same. Among them, the first size C1 is not a definite value, and in different embodiments, the size of the first size C1 is different. And it can be understood that, as used in the present application, "substantially" includes the stated value and the average value within an acceptable deviation range of the specific value, where the acceptable deviation range is determined by those of ordinary skill in the art considering the measurement being discussed and the error associated with the measurement of the specific quantity (i.e., the limitations of the measurement system).

[0049] By making the gap sizes between any two adjacent cell groups 301 substantially the same, the gaps between the color resist cells can uniformly appear in the first direction X. In this way, the light-emitting areas of different regions when light exits the pixel cells can be reduced, so as to ensure that the light-emitting areas and color gamuts of all pixel cells are consistent, thereby improving the display uniformity of the display device and reducing the light leakage phenomenon of the display device.

[0050] Referring to Figure 3 As shown, in an optional embodiment, the embodiment of the present application also discloses a display panel. In this display panel, in the first direction X, the gap size between two adjacent color resist cells 31 located in the same cell group 301 is substantially equal to the first size C1.

[0051] Specifically, the gap size between two adjacent color resist cells 31 within the same cell group 301 is substantially equal to the first size C1. At the same time, the gap sizes between any two adjacent cell groups 301 are also substantially equal to the first size C1. That is to say, in this embodiment, the gap sizes between any two adjacent color resist cells 31 in the first direction X are substantially the same.

[0052] This can make the gaps between the color resist cells 31 in the color film layer more uniform, so as to achieve the purpose of uniformly appearing the gaps between the color resist cells 31 in the first direction X and reduce the light leakage phenomenon occurring in the display device.

[0053] Referring to Figure 4 As shown, in an optional embodiment, the embodiment of the present application also discloses a display panel. In this display panel, in the first direction X, the gap size between two adjacent color resist cells 31 located in the same cell group 301 is substantially equal to the second size C2.

[0054] Specifically, in this embodiment, the gap size between two adjacent color resist cells 31 within the same cell group 301 is substantially equal to the second size C2, and the second size C2 is smaller than the first size C1. That is to say, within the same cell group 301, the gap size between two adjacent color resist cells 31 is smaller than the gap size between two adjacent cell groups 301.

[0055] In this way, the gaps between the color resist cells 31 in the color film layer will be arranged according to a certain rule. For example, referring to Figure 4As shown, when each unit group 301 includes three color filter units 31, in the first direction X, from the first row of color filter units to the ninth row of color filter units, the gap size between the first row of color filter units and the second row of color filter units and between the second row of color filter units and the third row of color filter units is the second size C2, the gap between the third row of color filter units and the fourth row of color filter units is the first size C2, the gap size between the fourth row of color filter units and the fifth row of color filter units and between the fifth row of color filter units and the sixth row of color filter units is the second size C2, the gap between the sixth row of color filter units and the seventh row of color filter units is the first size C1, and the gap size between the seventh row of color filter units and the eighth row of color filter units and between the eighth row of color filter units and the ninth row of color filter units is the second size C2.

[0056] Through such an arrangement, the gaps between the color filter units can also be made more uniform, thereby improving the display uniformity of the display panel.

[0057] In one embodiment, each unit group 301 includes two adjacent color filter units 31.

[0058] Specifically, when the gap size between two adjacent color filter units 31 is approximately equal to the first size C1, then in the first direction X, the gap size between any two adjacent color filter units is the first size C1.

[0059] Refer to Figure 5 As shown, when the gap size between two adjacent color filter units 31 is approximately equal to the second size C2, then in the first direction X, the gaps between the color filter units 31 appear in an alternating distribution pattern of the first size C1 and the second size C2. This can make the gap uniformity between the color filter units 31 higher and better reduce the light leakage phenomenon of the display panel.

[0060] At the same time, for the case where the gap size between two adjacent color filter units 31 is approximately equal to the second size C2, in the first direction X, the gap size between the first row of color filter units and the second row of color filter units is the second size C2, and the center distance between the first row of color filter units and the second row of color filter units is the first distance; the gap size between the second row of color filter units and the third row of color filter units is the first size C1, and the center distance between the second row of color filter units and the third row of color filter units is the second distance; since the second size C2 is smaller than the first size C1, the first distance is different from the second distance, and the size of the first distance is smaller than the size of the second distance.

[0061] In the embodiments of the present application, whether the gap size is approximately equal to the first size C1 or approximately equal to the second size C2, the gap size between two adjacent color filter units 31 can be adjusted by adjusting the position or size of the color filter block 311 in the color filter unit 31.

[0062] For example, when it is necessary to make the gap size between two adjacent color resistance units 31 approximately equal to the first size C1, if the gap size between two adjacent color resistance units 31 is greater than or less than the first size C1, the position of one of the color resistance units 31 can be adjusted to move the color resistance unit 31 towards or away from the other color resistance unit 31, so that the gap size between the two color resistance units 31 is adjusted to the first size C1.

[0063] For another example, when it is necessary to make the gap size between two adjacent color resistance units 31 approximately equal to the first size C1, if the gap size between two adjacent color resistance units 31 is greater than or less than the first size C1, the size of the color resistance block 311 in the first color resistance unit 31 in the first direction X can be adjusted to increase or decrease the size of the color resistance block 311 in the first direction X in the color resistance unit 31, so that the gap size between the two color resistance units 31 is adjusted to the first size C1.

[0064] For the case of adjusting the position of the color resistance unit 31, among two adjacent color resistance units 31 in the color film layer 30, the sizes of the color resistance blocks 311 with the same color included in the two adjacent color resistance units 31 in the first direction X are the same. It can be understood that when adjusting the position of the color resistance unit 31, the sizes of the respective color resistance blocks 311 in the color resistance unit 31 in the first direction X do not change, and the color resistance blocks 311 with the same color in the color resistance unit 31 are formed in the same process step. Therefore, the sizes of the color resistance blocks 311 with the same color included in two adjacent color resistance units 31 in the first direction X are the same. At the same time, the sizes of the color resistance blocks 311 with different colors included in two adjacent color resistance units 31 in the first direction X can also be the same.

[0065] For the case of adjusting the size of the color resistance block 311 in the color resistance unit 31 in the first direction X, refer to Figure 6 As shown, a plurality of color resistance units 31 may include a first color resistance unit 3011 and a second color resistance unit 3012, where the size of the color resistance block 311 included in the first color resistance unit 3011 in the first direction X is greater than the size of the color resistance block 311 included in the second color resistance unit 3012 in the first direction X. If the first color resistance unit 3011 and the second color resistance unit 3012 are two adjacent color resistance units 31, in this way, the gap size between the first color resistance unit 3011 and the second color resistance unit 3012 can be adjusted to the first size C1 or the second size C2.

[0066] Meanwhile, since it is necessary to adjust the gap size between any two adjacent unit groups 301 to the first size C1, or to adjust the gap size between any two adjacent color resistance units 31 in the same unit group 301 to the first size C1 or the second size C2, each unit group 301 includes at least one first color resistance unit 3011 and at least one second color resistance unit 3012. Exemplarily, referring to Figure 6 as shown, each unit group 301 may include one first color resistance unit 3011 and two second color resistance units 3012, and the first color resistance unit 3011 is adjacent to one second color resistance unit 3012 and to the second color resistance unit 3012 of the adjacent unit group 301, so that the gap size between any two adjacent color resistance units 31 is approximately equal to the first size C1, thereby improving the display uniformity of the display panel.

[0067] Referring to Figure 7 as shown, in one embodiment, when the unit group 301 includes one first color resistance unit 3011 and one second color resistance unit 3012. The first color resistance unit 3011 and the second color resistance unit 3012 may be alternately arranged in the first direction X, so that the gap size between two adjacent color resistance units 31 is approximately equal to the first size C1 or the second size C2.

[0068] In addition, referring to Figure 1 as shown, for the display panel provided by the embodiments of the present application, whether it is the adjustment of the position of the color resistance unit 31 or the adjustment of the size of the color resistance block 311 in the color resistance unit 31 in the first direction X, it is necessary to ensure that the positive projection of the anode 21 of each light-emitting device on the substrate 10 is within the positive projection range of the corresponding color resistance block 311 on the substrate 10. This can better reduce the light leakage phenomenon of the display panel and improve the display effect of the display panel.

[0069] Meanwhile, referring to Figure 4 as shown, in one embodiment, in the second direction Y, there is a gap between two adjacent color resistance blocks 311 in each color resistance unit 31, and the gap size between any two adjacent color resistance blocks 311 is approximately equal to the third size C3, that is, in the second direction Y, the gap size between any two adjacent color resistance blocks 311 in the same color resistance unit 31 is also the same. This can better ensure the uniformity between the color resistance blocks 311, thereby improving the display uniformity of the display panel.

[0070] In one embodiment, in the second direction Y, the gap size between any two adjacent color resistance blocks 311 is smaller than the smaller value of the first size C1 and the second size C2. Specifically, the value of the third size C3 is smaller than the smaller value of the first size C1 and the second size C2, so as to ensure that the gap size between two adjacent color resistance blocks 311 in the second direction Y is not greater than the gap size between two adjacent color resistance blocks 311 in the first direction X, thereby ensuring the display uniformity of the display panel.

[0071] In one embodiment, in the first direction X, the color resistance blocks 311 of two adjacent rows of color resistance units 31 are arranged in a staggered manner, and in two adjacent rows of color resistance units 31, the gap between the first color resistance block in the first row of color resistance units and the two second color resistance blocks adjacent to the first color resistance block in the second row of color resistance units is greater than the smaller value of the first size C1 and the third size C3. Specifically, when the color resistance blocks 311 of two adjacent rows of color resistance units 31 are arranged in a staggered manner, for any color resistance block (i.e., the first color resistance block) in two adjacent rows of color resistance units 31, there are two color resistance blocks (i.e., the second color resistance blocks) adjacent to this color resistance block in the other row of color resistance units 31, and the gap between these three color resistance blocks 311 is greater than the smaller value of the first size C1 and the third size C3, so as to ensure that the gap size between these three color resistance blocks 311 is more uniform and better improve the display uniformity of the display panel.

[0072] In one embodiment, referring to Figure 1 As shown, the display mirror panel may further include a packaging structure 40 disposed between the color filter layer and the light-emitting layer. The packaging structure 40 may include a first packaging layer 41, a second packaging layer 42, and a third packaging layer 43 that are sequentially stacked, and the first packaging layer 41 is disposed close to the light-emitting layer 30.

[0073] Specifically, the first packaging layer 41 and the third packaging layer 43 may be made of inorganic materials such as silicon nitride and silicon oxide. The first packaging layer 41 and the third packaging layer 43 may be obtained by chemical vapor deposition twice respectively, or may be formed by physical vapor deposition process; the second packaging layer 42 may be made of organic materials such as acrylic-based polymers and silicon-based polymers, and the second packaging layer 42 may be fabricated by inkjet printing process or may be formed by spraying process.

[0074] Meanwhile, a planarization layer 50 is disposed between the packaging structure 40 and the color filter layer 30. The material of the planarization layer 50 may be selected from silicon nitride or silicon oxide. The setting of the planarization layer 50 can be more conducive to the preparation of the color filter layer 30.

It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application. In addition, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations, nor can they be understood as indicating or implying relative importance. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or terminal device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or terminal device. Without further limitation, an element defined by the statement "comprising one..." does not exclude the existence of additional identical elements in the process, method, article or terminal device comprising the element.
