[0041] Figure 1 This is a schematic diagram of the structure of a display panel provided in an embodiment of the present utility model. Figure 2 for Figure 1 A schematic diagram of the first type of cross-section along section line A-A'. Figure 3 for Figure 1 A schematic diagram of the second type of cross-section along section line A-A'. Figure 4 for Figure 1 A schematic diagram of the fourth section along section line A-A', see reference. Figures 1 to 4 As shown, this utility model provides a display panel 10, which includes a substrate 100 and a plurality of light-emitting elements 200 located on one side of the substrate 100; the display panel 10 also includes a plurality of light-emitting adjustment structures 300, which are located on the side of the light-emitting elements 200 away from the substrate 100; along the first direction X1, the light-emitting adjustment structure 300 overlaps with the gap S between two adjacent light-emitting elements 200; the first direction X1 is the thickness direction of the display panel 10; the light-emitting adjustment structure 300 includes color resist structures 310 of at least two colors, and there is a cutout K between two adjacent light-emitting adjustment structures 300; along the first direction X1, at least some of the light-emitting elements 200 overlap with the cutout K.

[0042] Among them, reference Figure 1 As shown, the display panel 10 has a plurality of light-emitting elements 200 disposed on one side of the substrate 100. The light-emitting elements 200 emit light to realize the display function of the display panel 10. Further, refer to... Figure 2 As shown, the display panel 10 also has a plurality of pixel circuits 110 on one side of the substrate 100. The pixel circuits 110 are electrically connected to the light-emitting element 200 to drive the light-emitting element 200 and ensure that the light-emitting element 200 emits light for display.

[0043] The pixel circuit 110 can be configured in various ways, and the optional pixel circuit 110 may include transistors and storage capacitors. Based on the configuration of the pixel circuit 110, those skilled in the art can make adaptive adjustments according to their needs. Further, refer to... Figure 2As shown, the film structure of the pixel circuit 110 is disposed on one side of the substrate 100, and from the substrate 100 to the light-emitting side of the display panel 10, the layers can be an active layer 111, a gate layer 112, and a source / drain electrode layer 113, etc., and an insulating layer 120 disposed between the above-mentioned film layers. The specific film structure of the pixel circuit 110 can be adapted to the actual situation, and this embodiment of the present invention does not impose a specific limitation on it.

[0044] Furthermore, the types of light-emitting elements 200 in the display panel 10 are also diverse, including organic light-emitting units and micro-organic light-emitting elements. The specific type of light-emitting element 200 can be adaptively adjusted according to actual needs. For example, refer to... Figure 2 As shown, a micro-organic light-emitting unit, 200, is used as an example. The light-emitting element 200 includes a first electrode layer 200a, a common light-emitting layer 200b, and a second electrode layer 200c. The first electrode layer 200a is electrically connected to the pixel circuit 110. The common light-emitting layer 200b is located on the side of the first electrode layer 200a away from the substrate 100, and the second electrode layer 200c is located on the side of the common light-emitting layer 200b away from the first electrode layer 200a. The light-emitting principle of the light-emitting element 200 can be understood as follows: A certain voltage is applied to the first electrode layer 200a and the second electrode layer 200c, respectively. Holes from the first electrode layer 200a and electrons from the second electrode layer 200c converge in the light-emitting film layer of the common light-emitting layer 200b, where they are further excited to emit light, thus realizing the light emission of the light-emitting element 200.

[0045] Among them, reference Figure 2 As shown, the display panel 10 also includes a plurality of light emission adjustment structures 300, which are located on the side of the light-emitting element 200 away from the substrate 100. Along the first direction X1, the light emission adjustment structure 300 overlaps with the gap S between two adjacent light-emitting elements 200. That is, the orthographic projection of the light emission adjustment structure 300 on the substrate 100 overlaps with the orthographic projection of the gap between two adjacent light-emitting elements 200 on the substrate 100.

[0046] Furthermore, the light emission adjustment structure 300 includes color resist structures 310 for at least two colors. Figure 2The light emission adjustment structure 300 at various positions includes three different colored resist structures 310 (the first colored resist structure 311, the second colored resist structure 312, and the third colored resist structure 313 are illustrated in the figure). For example, the colored resist structure 310 may include a red, blue, green, and black colored resist structure, etc. The light emission adjustment structure 300 may include any two or more of the above-mentioned colored resist structures 310. For example, a light emission adjustment structure 300 composed of a red colored resist structure and a green colored resist structure. Specific combinations are not illustrated here. The number of colored resist structures 310 in the light emission adjustment structure 300 can be adaptively adjusted according to actual needs, and this embodiment of the invention does not impose specific limitations on this. Since the light emission adjustment structure 300 includes at least two different colored resist structures 310, it blocks the light-emitting element 200 that emits a single color of light. Since the orthographic projection of the light-emitting adjustment structure 300 on the substrate 100 overlaps with the orthographic projection of the gap between the two light-emitting elements 200 on the substrate 100, the light-emitting adjustment structure 300 can avoid crosstalk between light from light-emitting elements 200 of different colors, thereby improving the overall display effect of the display panel 10.

[0047] Further reference Figure 2 and Figure 4 As shown, a cutout K is provided between two adjacent light-emitting adjustment structures 300, and the orthographic projection of the cutout K on the substrate 100 overlaps with the orthographic projection of the light-emitting element 200 on the substrate 100. That is to say, at least one light-emitting element 200 in the display panel 10 has its light-emitting side not blocked by the color resist structure 310, which can improve the light emission rate of the corresponding light-emitting element 200, increase the display brightness of the light-emitting element 200, and help reduce the power consumption of the display panel 10.

[0048] For example, Figure 2 The example illustrates this by having four light-emitting adjustment structures 300 on the side of the three light-emitting elements 200 away from the substrate 100, and the four light-emitting adjustment structures 300 include three cutouts K between them. Figure 4 The example illustrates this by having three light-emitting adjustment structures 300 on the side of the three light-emitting elements 200 away from the substrate 100, and two cutouts K are included between the three light-emitting adjustment structures 300. The number of cutouts K can be adjusted adaptively according to the actual situation.

[0049] Optional, see reference Figures 2 to 4As shown, the display panel 10 may further include a thin-film encapsulation layer 500, which includes a first encapsulation layer 510, a second encapsulation layer 520, and a third encapsulation layer 530. The first encapsulation layer 510 is located on the side of the light-emitting element 200 away from the substrate 100, the second encapsulation layer 520 is located on the side of the first encapsulation layer 510 away from the light-emitting element 200, and the third encapsulation layer 530 is located on the side of the second encapsulation layer 520 away from the first encapsulation layer 510. The first encapsulation layer 510 and the third encapsulation layer 530 can be inorganic encapsulation layers, while the second encapsulation layer 520 can be an organic encapsulation layer. By setting the thin-film encapsulation layer 500, the encapsulation effect of the overall structure of the display panel 10 can be guaranteed, the stability of the structure can be improved, and the overall flatness of the display panel 10 can also be improved.

[0050] Optional, see reference Figure 3 As shown, the display panel 10 also includes a cover plate 600 located on the side of the light-emitting adjustment structure 300 away from the substrate 100. The cover plate 600 is used to protect the display panel 10 and prevent the film structure in the display panel 10 from being impacted by external forces. For example, the cover plate 600 can be made of glass, which does not affect the overall display effect of the display panel 10. Furthermore, the display panel 10 also includes a transparent filler 610, which is disposed on the side of the cover plate 600 near the substrate 100 to ensure the cover plate 600 is fixed. Other film structures can also be added or removed from the display panel 10; these will not be described in detail here.

[0051] Optional, see reference Figure 3 As shown, the display panel 10 also includes a planarization film layer 700 located on both sides of the light emission adjustment structure 300 along the first direction X1. By setting the planarization module 700, the overall flatness of the display panel 10 can be ensured. Specifically, the planarization module 700 includes a first planarization layer 710 and a second planarization layer 720, wherein the first planarization layer 710 is located on the side of the light emission adjustment structure 300 closer to the substrate 100, and the second planarization layer 720 is located on the side of the light emission adjustment structure 300 away from the substrate 100.

[0052] In summary, this embodiment of the invention provides a display panel with multiple light adjustment structures disposed on the side of the light-emitting element away from the substrate. Along the thickness direction of the display panel, the light adjustment structures overlap with the gaps between adjacent light-emitting elements, and each light adjustment structure includes color resist structures of at least two colors. Therefore, the light adjustment structures can block light of one color, avoiding crosstalk between light-emitting elements of different colors and improving the display effect of the display panel. Simultaneously, a cutout is provided between adjacent light adjustment structures, and along the thickness direction of the display panel, at least a portion of the light-emitting element overlaps with the cutout. This can increase the light extraction rate of the light-emitting element, improve its display brightness, and help reduce the power consumption of the display panel.

[0053] Continue to refer to Figure 2 and Figure 4 As shown, the plurality of light-emitting elements 200 include a first color light-emitting element 201, a second color light-emitting element 202 and a third color light-emitting element 203. The color purity of the first color light-emitting element 201 is greater than that of the second color light-emitting element 202, and the color purity of the second color light-emitting element 202 is greater than that of the third color light-emitting element 203. Along the first direction X1, at least the first color light-emitting element 201 overlaps with the cutout K.

[0054] refer to Figure 2 and Figure 4 As shown, the light-emitting elements 200 in the display panel 10 include a first color light-emitting element 201, a second color light-emitting element 202, and a third color light-emitting element 203. By driving the first color light-emitting element 201, the second color light-emitting element 202, and the third color light-emitting element 203 to emit light, the display panel 10 achieves a color display effect.

[0055] Specifically, when the light-emitting element 200 emits light of different colors, the purity of the emitted light color varies among the different colored light-emitting elements 200. The purity of the emitted light color of the first-color light-emitting element 201 is greater than that of the second-color light-emitting element 202, and the purity of the emitted light color of the second-color light-emitting element 202 is greater than that of the third-color light-emitting element 203. In other words, the color of the light emitted by the first-color light-emitting element 201 is closer to the first color. Optionally, the first-color light-emitting element 201 may include a green light-emitting element, the second-color light-emitting element 202 may include a blue light-emitting element, and the third-color light-emitting element 203 may include a red light-emitting element.

[0056] The color resist structure 310, which forms the light emission adjustment structure 300, has different colors and can adjust the emitted light from the light-emitting element 200. For example, the third-color light-emitting element 203 has a relatively weak color purity. Figure 4As shown, the third color light-emitting element 203 and the corresponding color resist structure 310 ( Figure 4 (As shown in the diagram with the third color resist structure 313), the light emitted by the third color light-emitting element 203 is adjusted by the corresponding color resist structure 310, resulting in an emitted light that is closer to the third color. Furthermore, for light-emitting elements 200 with higher color purity, the emitted light is closer to the original color, thus eliminating the need for color filtering adjustment on the light-emitting side of the light-emitting element 200. Therefore, along the first direction X1, at least the first color light-emitting element 201 overlaps with the cutout K. In other words, the first color light-emitting element 201 does not need color resist structure 310 to adjust its emitted color on the light-emitting side. In this way, while ensuring the color purity of the first color light-emitting element 201, the light extraction rate of the first color light-emitting element 201 can be increased, the brightness of the first color light-emitting element 201 can be improved, and the power consumption of the display panel 10 can be reduced.

[0057] Optional, see reference Figure 2 and Figure 4 As shown, along the first direction X1, the second color light-emitting element 202 also overlaps with the cutout K. (Reference) Figure 2 As shown, along the first direction X1, the third color light-emitting element 203 also overlaps with the cutout K; Reference Figure 4 As shown, along the first direction X1, the third color light-emitting element 203 also does not overlap with the cutout K. The specific arrangement of the different color light-emitting elements 200 in the display panel 10 can be adaptively adjusted according to actual needs; this embodiment of the invention does not impose specific limitations on this.

[0058] refer to Figure 4 As shown, along the first direction X1, the third color light-emitting element 203 overlaps with the light-emitting adjustment structure 300; the color of the color resist structure 310 included in the light-emitting adjustment structure 300 that overlaps with the third color light-emitting element 203 is the same as the light-emitting color of the third color light-emitting element 203.

[0059] For details, please refer to Figure 4 As shown, along the first direction X1, the third color light-emitting element 203 overlaps with the light-emitting adjustment structure 300, and the orthographic projection of a color resist structure 310 in the light-emitting adjustment structure 300 onto the substrate 100 overlaps with the orthographic projection of the third color light-emitting element 203 onto the substrate 100. The color resist structure 310 overlapping with the third color light-emitting element 203 ( Figure 4 The color of the third color resist structure 310 (shown in the middle) is the same as the color emitted by the third color light-emitting element 203. Therefore, the color resist structure 310 can adjust the light emitted by the third color light-emitting element 203, thereby improving the purity of the emitted color of the third color light-emitting element 203 and improving the overall display effect of the display panel 10.

[0060] Figure 5 for Figure 1 A schematic diagram of the fifth type of cross-section along section line A-A'. Figure 6 for Figure 1 A schematic diagram of the sixth type of cross-section along section line A-A'. Figure 7 for Figure 1 A schematic diagram of the seventh section along the central section line A-A', see reference. Figures 5 to 7 As shown, the light emission adjustment structure 300 includes a first adjustment portion 300a, a second adjustment portion 300b, and a third adjustment portion 300c. Along the second direction X2, the second adjustment portion 300b is located between the first adjustment portion 300a and the third adjustment portion 300c. The second direction X2 intersects the first direction X1. The first adjustment portion 300a includes a color resist structure 310 of one color and the same light emission color as the light-emitting element 200 adjacent to it. The second adjustment portion 300b includes color resist structures 310 of at least two colors stacked along the first direction X1, or the second adjustment portion 300b includes a black color resist structure 320. The third adjustment portion 300c includes a color resist structure 310 of one color and the same light emission color as the light-emitting element 200 adjacent to it.

[0061] Among them, reference Figures 5 to 7 As shown, the light emission adjustment structure 300 includes a first adjustment portion 300a, a second adjustment portion 300b, and a third adjustment portion 300c, wherein the first adjustment portion 300a and the third adjustment portion 300c are located on both sides of the second adjustment portion 300b along the second direction X2. Each of the first adjustment portion 300a, the second adjustment portion 300b, and the third adjustment portion 300c includes at least one color resist structure 310.

[0062] Specifically, the first adjustment section 300a includes a color resist structure 310 of the same color as the light emitted by the nearby light-emitting element 200. Therefore, the arrangement of the first adjustment section 300a will not block the emitted light from the nearby light-emitting element 200, thereby ensuring the light emission efficiency of the light-emitting element 200 and the overall display effect of the display panel 10. Similarly, the third adjustment section 300c includes a color resist structure 310 of the same color as the light emitted by the nearby light-emitting element 200. Therefore, the arrangement of the third adjustment section 300c will also not block the emitted light from the nearby light-emitting element 200, thereby ensuring the light emission efficiency of the light-emitting element 200 and the overall display effect of the display panel 10.

[0063] For example, refer to Figures 5 to 7As shown, taking the light emission adjustment structure 300 between the second color light-emitting element 202 and the first color light-emitting element 201 as an example, the first adjustment portion 300a is closest to the second color light-emitting element 202. The color of the color resist structure 310 (illustrated as the second color resist structure 312 in the figure) included in the first adjustment portion 300a is consistent with the emitted light color of the second color light-emitting element 202, and the first adjustment portion 300a does not block the light emitted by the second color light-emitting element 202. Simultaneously, the third adjustment portion 300c is closest to the first color light-emitting element 201. The color of the color resist structure 310 (illustrated as the first color resist structure 311 in the figure) included in the third adjustment portion 300c is consistent with the emitted light color of the first color light-emitting element 201, and the third adjustment portion 300c does not block the light emitted by the first color light-emitting element 202. This ensures the overall display effect of the display panel 10.

[0064] Furthermore, the second adjustment portion 300b is located along the second direction X2 between the first adjustment portion 300a and the third adjustment portion 300c. The second adjustment portion 300b, on its orthographic projection onto the substrate 100, is positioned between the orthographic projection of the first adjustment portion 300a or the third adjustment portion 300c onto the substrate 100 and the orthographic projection of the adjacent light-emitting element 200 on the substrate 100. In other words, the distance between the second adjustment portion 300b and the light-emitting element 200 is relatively far, and the placement of the second adjustment portion 300b will not affect the normal light emission of the light-emitting element 200. Since the second adjustment portion 300b is located between two adjacent light-emitting elements 200, its placement can be used to block light between light-emitting elements 200 of different colors, preventing color crosstalk in the display panel 10. Specifically, refer to... Figure 5 As shown, the second adjustment section 300b includes at least two color resist structures 310 stacked along the first direction X1. Figure 5 (The example includes a first color resist structure 311, a second color resist structure 312, and a third color resist structure 313.) See reference. Figure 6 and Figure 7 The second adjustment section 300b shown includes a black color resist structure 320. The number and type of the specific color resist structures 310 in the second adjustment section 300b can be adaptively adjusted according to actual needs.

[0065] Continue to refer to Figures 5 to 7 As shown, along the first direction X1, the light emission adjustment structure 300 covers the gap S between two adjacent light-emitting elements 200, and the gap S between two adjacent light-emitting elements 200 covers the second adjustment portion 300b.

[0066] Further reference Figures 5 to 7 As shown, the orthographic projection of the light emission adjustment structure 300 on the substrate 100 covers the orthographic projection of the gap S between two adjacent light-emitting elements 200 on the substrate 100. That is, a portion of the light emission adjustment structure 300 overlaps with the light emission area of ​​the adjacent light-emitting element 200 along the first direction X1. Since the first adjustment portion 300a includes a color resist structure 310 of one color and has the same light emission color as the light-emitting element 200 adjacent to it, or the third adjustment portion 300c includes a color resist structure 310 of one color and has the same light emission color as the light-emitting element 200 adjacent to it, the light emission adjustment structure 300 will not affect the light emission of the light-emitting element 200, and the setting of the light emission adjustment structure 300 will not interfere with the normal display effect of the light-emitting element 200.

[0067] The orthographic projection of the gap S between two adjacent light-emitting elements 200 onto the substrate 100 covers the orthographic projection of the second adjustment portion 300b onto the substrate 100. In other words, the second adjustment portion 300b, which blocks light, will not interfere with the normal light emission of the light-emitting elements 200, thus preventing crosstalk between light-emitting elements 200 of different colors. Therefore, the light emission adjustment structure 300 ensures the overall display effect of the display panel 10.

[0068] Continue to refer to Figures 5 to 7 As shown, along the first direction X1, the first adjustment portion 300a and the portion of the light-emitting element 200 adjacent to it overlap, and the third adjustment portion 300b and the portion of the light-emitting element 200 adjacent to it overlap.

[0069] For details, please refer to Figures 5 to 7As shown, along the first direction X1, the first adjustment portion 300a and the adjacent light-emitting element 200 partially overlap, illustrated as region a1 in the figure; along the first direction X1, the third adjustment portion 300b and the adjacent light-emitting element 200 partially overlap, illustrated as region a2 in the figure. Furthermore, since the first adjustment portion 300a includes a color resist structure 310 of one color and emits the same color as the adjacent light-emitting element 200, the overlapping area between the first adjustment portion 300a and the adjacent light-emitting element 200 will not interfere with the light emission of the light-emitting element 200; similarly, the third adjustment portion 300c includes a color resist structure 310 of one color and emits the same color as the adjacent light-emitting element 200, therefore the overlapping area between the third adjustment portion 300c and the adjacent light-emitting element 200 will not interfere with the light emission of the light-emitting element 200. Furthermore, along the first direction X1, the first adjustment portion 300a and the portion of the light-emitting element 200 adjacent to it overlap, and the third adjustment portion 300b and the portion of the light-emitting element 200 adjacent to it overlap. Color filtering adjustment can also be performed on the edge of the light-emitting element 200 near the light-emitting adjustment structure 300 to ensure that the light-emitting effect of the center and the edge of the light-emitting element 200 is balanced and to improve the light-emitting effect of the light-emitting element 200.

[0070] Figure 8 for Figure 1 A schematic diagram of the eighth section along the central section line A-A'. Figure 9 for Figure 1 A schematic diagram of the ninth section along section line A-A', see reference. Figure 8 and Figure 9 As shown, the plurality of light-emitting elements 200 include a first color light-emitting element 201, a second color light-emitting element 202, and a third color light-emitting element 203; the color purity of the first color light-emitting element 201 is greater than that of the second color light-emitting element 202, and the color purity of the second color light-emitting element 202 is greater than that of the third color light-emitting element 203; the first color light-emitting element 201 and the light-emitting adjustment structure 300 overlapping with it have a first overlapping area M1, the second color light-emitting element 202 and the light-emitting adjustment structure 300 overlapping with it have a second overlapping area M2, and the third color light-emitting element 203 and the light-emitting adjustment structure 300 overlapping with it have a third overlapping area M3; the first overlapping area M1 is less than or equal to the second overlapping area M2, and the second overlapping area M2 is less than or equal to the third overlapping area M3.

[0071] The display panel 10 includes light-emitting elements 200 of different colors. The light-emitting color purity of the first color light-emitting element 201 is greater than that of the second color light-emitting element 202, and the light-emitting color purity of the second color light-emitting element 202 is greater than that of the third color light-emitting element 203. Therefore, the area of ​​the overlapping region between the light-emitting adjustment structure 300 and the light-emitting element 200 along the first direction X1 can be adjusted differently according to the light-emitting color purity of the different color light-emitting elements 200, thereby improving the overall light emission effect of the display panel 10.

[0072] Specifically, since the color purity of the first color light-emitting element 201 is greater than that of the second color light-emitting element 202, the first overlap area M1 between the first color light-emitting element 201 and the light-emitting adjustment structure 300 overlapping with it can be adjusted (see reference). Figure 8 and Figure 9 In the middle, the sum of the areas corresponding to regions b1 and b2 is less than the second overlap area M2 between the second color light-emitting element 202 and the light-emitting adjustment structure 300 overlapping with it (reference). Figure 8 and Figure 9 In the middle, the areas corresponding to regions b3 and b4 are summed. Furthermore, the emission color purity of the second color light-emitting element 202 is greater than that of the third color light-emitting element 203, therefore the first overlap area M2 between the second color light-emitting element 202 and the light-emitting adjustment structure 300 overlapping with it can be adjusted (refer to...). Figure 8 and Figure 9 In the middle, the sum of the areas corresponding to regions b3 and b4 is less than the second overlap area M3 between the third color light-emitting element 203 and the light-emitting adjustment structure 300 overlapping with it (reference). Figure 8 In the middle, the sum of the areas corresponding to regions b5 and b6). Where, reference... Figure 9 As shown, for the third color light-emitting element 203 with low color purity, the second overlap area M3 between the third color light-emitting element 203 and the light-emitting adjustment structure 300 overlapping with it can also be as follows: Figure 9 As shown (reference) Figure 9 (In the text, the area corresponding to region b7 is summed.) (Reference) Figure 8 and Figure 9 As shown, the second overlapping area M2 is less than or equal to the third overlapping area M3.

[0073] In other words, for light-emitting elements 200 with low color purity, the overlap area between them and the light-emitting adjustment structure 300 is increased, and the light-emitting adjustment structure 300 is used to perform color filtering adjustment on the light-emitting element 200 to improve the light-emitting effect of the light-emitting element 200.

[0074] refer to Figures 2 to 9As shown, the display panel 10 also includes a pixel limiting layer 400, which includes a plurality of pixel limiting structures 410 and a pixel opening 411 located between two adjacent pixel limiting structures 410; a light-emitting element 200 is disposed in the pixel opening 411; along the first direction X1, the light-emitting adjustment structure 300 overlaps with the pixel limiting structure 410.

[0075] refer to Figures 2 to 9 As shown, the display panel 10 also includes a pixel defining layer 400, which includes a plurality of pixel defining structures 410. A pixel opening 411 is provided between two adjacent pixel defining structures 410, wherein the pixel opening 411 exposes a portion of the light-emitting element 200. That is, the light-emitting element 200 emits light at the pixel opening 411, thereby achieving the display effect of the display panel 10.

[0076] Further reference Figures 2 to 9 As shown, the orthographic projection of the light-emitting adjustment structure 300 on the substrate 100 overlaps with the orthographic projection of the gap between two adjacent light-emitting elements 200 on the substrate 100. In other words, the light-emitting adjustment structure 300 is located on the side of the pixel-limiting structure 410 away from the substrate 100. The pixel-limiting structure 410 provides space for the light-emitting adjustment structure 300, ensuring that the display panel 10 utilizes the light-emitting adjustment structure 300 to improve the overall display effect of the display panel 10.
