[0004] However, the above-mentioned film layer for realizing the touch function increases the thickness of the display panel, resulting in poor lightness and thinness of the display panel. Utility Model Content

[0052] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0053] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0054] Figure 1FIG2 is a schematic diagram of the structure of a display panel provided by related art. The display panel 20 includes a driving backplane 21, a light-emitting device 22, a touch layer 23, a color resist layer 24, and a black matrix layer 25. The touch layer 23 includes a first touch electrode layer 231, a first touch insulating layer 232, a second touch electrode layer 233, and a second touch insulating layer 234, stacked in a direction away from the driving backplane 21. The light-emitting device 22 can be used to emit a large amount of light. However, for light at large angles, such as light L1 and light L2, the black matrix layer 25 blocks some of the light emitted by the light-emitting device 22, resulting in loss of some of the light, which in turn leads to low forward light extraction efficiency of the display panel 20.

[0055] In addition, the color resist layer 24 needs to cover the edge portion of the black matrix layer 25 to prevent peeling of the color resist layer 24. However, the color resist layer 24 has poor flatness at the contact portion with the black matrix layer 25, which easily leads to uneven light reflection and thus causes color separation.

[0056] The present application provides a display panel. Figure 2 , Figure 2 1 is a schematic diagram of the structure of a display panel provided in an embodiment of the present application. The display panel 10 includes a driving backplane 11, a light-emitting device 12, a touch layer 13, and a color resist layer 14. Here, the display panel 10 may be an organic light-emitting diode (OLED) display panel. OLED display panels have many advantages, including self-luminescence, low driving voltage, high luminous efficiency, short response time, high clarity and contrast, a wide operating temperature range, and the ability to achieve flexible display and large-area full-color display.

[0057] There are multiple light-emitting devices 12, and the multiple light-emitting devices 12 are all located on the same side of the driving backplane 11. Here, the driving backplane 11 is used to carry other film layers in the display panel 10, and the driving backplane 11 includes a thin film transistor (TFT) array. The light-emitting device 12 is used to emit a light beam in a direction away from the driving backplane 11. The multiple light-emitting devices 12 can be electrically connected to the thin film transistor in the driving backplane 11, so that the driving backplane 11 can control the light-emitting state and light-emitting brightness of each light-emitting device 12. Exemplarily, the light-emitting device 12 can be an organic light-emitting diode, and the light-emitting device 12 can include: a first electrode, an organic light-emitting layer, and a second electrode arranged in a stacked manner, and the first electrode and the second electrode cooperate to drive the organic light-emitting layer to emit light.

[0058] The touch layer 13 is located on the side of the multiple light-emitting devices 12 away from the driving backplane 11. The touch layer 13 includes: a first touch electrode layer 131, a touch insulation layer 132 and a second touch electrode layer 133 stacked in a direction away from the driving backplane 11. The touch insulation layer 132 has a plurality of dimming holes H1. The plurality of dimming holes H1 correspond to the multiple light-emitting devices 12, and the orthographic projection of the dimming holes H1 on the driving backplane 11 overlaps with the orthographic projection of the corresponding light-emitting device 12 on the driving backplane 11.

[0059] Here, the touch layer 13 can adopt a flexible multi-layer structure technology (Flexible Multi Layer On Cell, FMLOC), that is, the touch layer 13 is integrated into the display panel 10 using a patterning process, so that the display touch integration can be achieved. Among them, the first touch electrode layer 131 and the second touch electrode layer 133 may include a self-capacitive capacitor structure or a mutual-capacitive capacitor structure. When the user's finger contacts the touch electrode, the capacitance value in the self-capacitive capacitor structure or the mutual-capacitive capacitor structure will change to determine the location where the touch occurs, so that the display panel 10 can achieve the touch function. The touch insulating layer 132 can play an insulating role between the first touch electrode layer 131 and the second touch electrode layer 133. The multiple dimming holes H1 in the touch insulating layer 132 can be used to accommodate multiple color resist blocks 141, which can reduce the thickness of the display panel 10. Exemplarily, the material of the touch insulating layer 132 may include an organic material. For example, the touch insulating layer 132 may be a transparent overcoat (OC) layer, or the touch insulating layer 132 may be an organic layer with light filtering properties.

[0060] The color resist layer 14 is located on a side of the light emitting devices 12 away from the driving backplane 11 . The color resist layer 14 includes a plurality of color resist blocks 141 . The plurality of color resist blocks 141 correspond to the plurality of dimming holes H1 . At least a portion of the color resist blocks 141 is located in the corresponding dimming holes H1 .

[0061] Here, the color filter layer 14 can utilize color filter on encapsulation (COE) technology. COE technology replaces polarizers by manufacturing a color filter layer 14, which can reduce the thickness of the display panel 10 and improve the brightness. Since multiple color filter blocks 141 correspond to multiple dimming holes H1, and multiple dimming holes H1 correspond to multiple light-emitting devices 12, multiple color filter blocks 141 can correspond to multiple light-emitting devices 12. This allows the orthographic projections of the color filter blocks 141 on the driver backplane 11 to overlap with the orthographic projections of the corresponding light-emitting devices 12 on the driver backplane 11. In this way, light emitted by each light-emitting device 12 can pass through the corresponding color filter block 141 before exiting. As light emitted by a light-emitting device 12 passes through the corresponding color filter block 141, the color filter block 141 can transmit light of a specific color from the light emitted by the light-emitting device 12 while filtering out light of other colors, thereby ensuring good color accuracy when the display panel 10 displays images.

[0062] Furthermore, natural light incident from the light-emitting side first passes through the color-resistance layer 14 and enters the interior of the display panel. The color-resistance layer 14, which can only transmit a single color of light, filters out most of the light. The small amount of light that enters the interior of the display panel will be lost when it is reflected by the metal material inside the display panel and the microcavity of the light-emitting device 12. When the reflected light is emitted through the color-resistance layer 14, it will again be filtered by the color-resistance layer 14, further reducing the intensity of the emitted reflected light, thereby reducing the reflectivity.

[0063] It should be noted that at least a portion of the color-resist block 141 is located in the corresponding dimming hole H1 , which may occur in various situations. Figure 2 Only the case where the entire color resist block 141 is located within the corresponding dimming hole H1 is shown. This can improve the flatness of the color resist block 141, but the present application is not limited to this. For example, a portion of the color resist block 141 can be located within the corresponding dimming hole H1, while another portion of the color resist block 141 can be located outside the corresponding dimming hole H1. Since the material of the color resist block 141 and the material of the touch insulation layer 132 can both be organic materials, by arranging the color resist block 141 to fill the corresponding dimming hole H1, the color resist block 141 and the touch insulation layer 132 can form a single layer structure, thereby effectively improving the strength of the touch insulation layer 132, thereby ensuring the strength of the display panel 10.

[0064] In summary, in the display panel provided by the embodiments of the present application, the touch insulating layer has multiple dimming holes. By providing multiple color resist blocks corresponding to the multiple dimming holes, and the multiple dimming holes corresponding to the multiple light-emitting devices, the multiple color resist blocks can correspond to the multiple light-emitting devices, thereby enabling the color resist blocks to filter light for the corresponding light-emitting devices. Furthermore, by disposing at least a portion of the color resist blocks within the corresponding dimming holes, the thickness of the display panel can be reduced, thereby achieving a thinner and lighter display panel.

[0065] Alternatively, refer to Figure 2 , the color resist block 141 contacts the inner wall of the corresponding dimming hole H1, and the refractive index of the color resist block 141 is greater than the refractive index of the touch insulating layer 132. Here, for the large-angle light emitted by the light-emitting device 12, for example, when the light L3 and the light L4 reach the interface between the color resist block 141 and the touch insulating layer 132, the effect of forward light extraction can be achieved based on the difference in the refractive index of the color resist block 141 and the touch insulating layer 132, that is, the light L3 and the light L4 can be deflected to a direction perpendicular to the driving backplane 10 at the interface, which can avoid the loss of large-angle light, thereby improving the forward light extraction efficiency and brightness of the display panel 10. Exemplarily, the refractive index of the color resist block 141 can be in the range of 1.6-1.8, for example, 1.7. The refractive index of the touch insulating layer 132 can be in the range of 1.2-1.5, for example, 1.5.

[0066] The structure of the dimming hole is described below:

[0067] Please refer to the structure of a dimming hole provided in this application Figure 2 , the inner wall of the dimming hole H1 is sloped, and the angle between the inner wall of the dimming hole H1 and the plane where the lower opening of the dimming hole H1 is located is an obtuse angle, which can facilitate the forward light extraction of light at a large angle. When the inner wall of the dimming hole H1 includes only one slope, the shape of the cross section of the dimming hole H1 perpendicular to the driving backplane 11 can be an inverted trapezoid, which can facilitate manufacturing. The inner wall of the dimming hole H1 can also include multiple continuous slopes, and the angles between each slope and the plane where the lower opening of the dimming hole H1 is located can be different. Multiple slopes can also achieve a forward light extraction effect. However, there is still a risk of peeling off the color resist block 141 at the inner wall of the dimming hole H1. The present application can set the color resist block 141 to contact the upper surface of the touch insulation layer 132 to avoid peeling.

[0068] The embodiment of the present application also provides another dimming hole structure, that is, the inner wall of the dimming hole can be a stepped structure to prevent the color block from peeling off. Figure 3 , Figure 3Schematic diagram of another display panel structure provided by an embodiment of the present application. At least part of the dimming hole H1 includes: a first sub-via hole H11 and a second sub-via hole H12 connected to the first sub-via hole H11. The first sub-via hole H11 is closer to the driving backplane 11 than the second sub-via hole H12.

[0069] The first sub-via H11 has a first opening K1 on the side facing away from the driver backplate 11, and the second sub-via H12 has a second opening K2 on the side facing the driver backplate 11. The size of the first opening K1 is smaller than the size of the second opening K2, that is, the orthographic projection of the first opening K1 on the driver backplate 11 is located within the orthographic projection of the second opening K2 on the driver backplate 11, so that a step surface M1 is formed between the first opening K1 and the second opening K2. Here, the step surface M1 is connected to the inner wall M2 of the first sub-via H11 and the inner wall M3 of the second sub-via H12, respectively. The step surface M1 can be parallel to the driver backplate 11 to increase the bonding strength between the color resist block 141 and the touch insulation layer 132. Due to manufacturing errors, etc., this application does not strictly require that the step surface M1 is absolutely parallel to the driver backplate 11. For example, "parallel" can refer to approximately parallelism with a deviation range of less than 5 degrees.

[0070] The portion of the color resist block 141 located within the dimming hole H1 contacts the inner wall M2 of the first sub-via hole H11 and the inner wall M3 of the second sub-via hole H12 , and contacts the step surface M1 .

[0071] In this way, at the step surface M1, the bonding strength between the color resist block 141 and the touch insulating layer 132 is high, thereby reducing the risk of the color resist block 141 peeling off. There is no need to set the color resist block to contact the upper surface of the touch insulating layer 132, thereby effectively improving the flatness of the color resist block 141 while ensuring that it does not peel off. However, the present application is not limited to this. Figure 3 In the structure of the dimming hole H1 shown, the color resist block 141 may also contact the upper surface of the touch insulating layer 132 , which can further ensure that the color resist block 141 is attached to the touch insulating layer 132 .

[0072] Alternatively, refer to Figure 3 and Figure 4 , Figure 4 yes Figure 3An enlarged schematic diagram of part of the structure in the display panel is provided. The first sub-via H11 has a third opening K3 on the side facing the driving backplane 11. The angle α1 between the plane where the third opening K3 is located and the inner wall M2 of the first sub-via H11 is an obtuse angle. And the angle α2 between the step surface M1 and the inner wall M3 of the second sub-via H12 is an obtuse angle. In this way, it can be ensured that light at a large angle can be taken in in the forward direction, reducing the loss of light at a large angle. Exemplarily, the angle range of the angle α1 and the angle α2 can be: 105 degrees to 150 degrees. Moreover, the smaller the angle α1 and the angle α2 are, the more the light at a large angle tends to be emitted in the forward direction, that is, the better the forward light extraction effect for light at a large angle.

[0073] Optionally, the width D1 of the step surface M1 is greater than or equal to 4.5 microns in a direction parallel to the driving backplane 11. When the width D1 is within this range, the color resist block 141 can be effectively overlapped with the touch insulating layer 132, thereby preventing the color resist block 141 from peeling off.

[0074] Optionally, the second sub-via H12 has a fourth opening K4 on the side facing away from the driver backplate 11. In a direction perpendicular to the driver backplate 11, the distance D2 between the step surface M1 and the surface containing the third opening K3 ranges from 1.2 microns to 2 microns, and the distance D3 between the step surface M1 and the surface containing the fourth opening K4 ranges from 1.5 microns to 2 microns. Distances D2 and D3 within this range not only facilitate the manufacture of the dimming hole H1, but also prevent the first and second sub-via holes H11 and H12 from being too deep, which could easily cause material residue on the color resist block 141, and prevent the touch insulation layer 132 from being too thick, which could affect light transmittance.

[0075] In the present application, a halftone mask can be used to achieve a stepped inner wall structure of the dimming hole H1. For example, after forming a full layer of the touch insulation layer 132, the touch insulation layer 132 can be exposed and developed using a halftone mask. Because the halftone mask includes multiple regions with different light transmittances, the halftone mask can control the degree of light transmission to achieve different degrees of exposure in the multiple regions, thereby adjusting the depth of the first sub-via hole H11 and the second sub-via hole H12, thereby forming multiple dimming holes H1 with stepped inner walls.

[0076] It should be noted that, due to the manufacturing process error, the embodiment of the present application does not strictly require the inner wall of the dimming hole H1 to be a plane. For example, the inner wall of the dimming hole H1 can also be a curved surface, which can also achieve the effect of forward light extraction.

[0077] The present application provides another display panel. Figure 5 , Figure 5This is a schematic diagram of the structure of another display panel provided in an embodiment of the present application. The plurality of light-emitting devices 12 include: a plurality of first light-emitting devices 12a, a plurality of second light-emitting devices 12b, and a plurality of third light-emitting devices 12c. The first light-emitting devices 12a are configured to emit light of a first color, the second light-emitting devices 12b are configured to emit light of a second color, and the third light-emitting devices 12c are configured to emit light of a third color. The first color is one of red, blue, and green; the second color is another of red, blue, and green; and the third color is another of red, blue, and green.

[0078] The plurality of color resist blocks 141 include at least one of a first color resist block 141a having a first color, a second color resist block 141b having a second color, and a third color resist block 141c having a third color. In other words, the plurality of color resist blocks 141 may be color resist blocks 141 of a single color, or may be color resist blocks 141 of two colors, or may be color resist blocks 141 of three colors.

[0079] The following describes the types of color blocks included in the display panel using three exemplary embodiments:

[0080] In the first exemplary embodiment, please refer to Figure 6 , Figure 6 This is a schematic diagram of the structure of another display panel provided by an embodiment of the present application. The multiple color-block blocks 141 are each first color-block blocks 141a. Each of the multiple first color-block blocks 141a corresponds one-to-one with each of the multiple first light-emitting devices 12a. The orthographic projections of the first color-block blocks 141a on the driver backplane 11 overlap with the orthographic projections of the corresponding first light-emitting devices 12a on the driver backplane 11. In this way, the multiple color-block blocks 141 can filter only the light beams emitted by the first light-emitting devices 12a, thereby improving the color purity of the light beams emitted by the first light-emitting devices 12a.

[0081] The touch insulating layer 132 has a light filtering property, and is configured to transmit the second and third color lights while blocking other colors of light. In other words, the touch insulating layer 132 can be made of a material that selectively transmits the second and third color lights, and exhibits a high transmittance only for the second and third color lights.

[0082] The orthographic projections of the second and third light-emitting devices 12b and 12c on the driver backplane 11 are both located within the orthographic projection of the touch insulation layer 132 on the driver backplane 11. Thus, after the light beams emitted by the second and third light-emitting devices 12b and 12c reach the touch insulation layer 132, the touch insulation layer 132 only allows the second and third colors of light to pass through. Therefore, the touch insulation layer 132 filters the light beams emitted by the second and third light-emitting devices 12b and 12c, thereby improving the color purity of the light beams emitted by the second and third light-emitting devices 12b and 12c. Furthermore, the display panel 10 does not need to include the color resist block 141 corresponding to the second and third light-emitting devices 12b and 12c, thereby saving two masks and reducing manufacturing costs. Regarding external ambient light, the touch insulating layer 132 can also absorb light except the second color light and the third color light, so the touch insulating layer 132 can reduce the reflectivity.

[0083] For example, in a first exemplary embodiment, the color of the first color resist block 141a can be green, and the touch insulating layer 132 can transmit red and blue light, and block light of other colors. Alternatively, the color of the first color resist block 141a can be blue, and the touch insulating layer 132 can transmit red and green light, and block light of other colors. Alternatively, the color of the first color resist block 141a can be red, and the touch insulating layer 132 can transmit blue and green light, and block light of other colors.

[0084] Because the second touch electrode layer 133 is made of metal, it may reflect ambient light, affecting the display quality of the display panel 10. Furthermore, there is a risk of crosstalk in the area between two adjacent light-emitting devices 12. In this application, various implementations can be used to reduce reflectivity and avoid crosstalk. The following describes two implementations, taking the first exemplary embodiment as an example:

[0085] For the first implementation, please refer to Figure 6 The color resist blocks 141 are all located within the corresponding dimming holes H1. Therefore, the color resist blocks 141 do not overlap with the black matrix layer 15 or the upper surface of the touch insulation layer 132. Therefore, the color resist blocks 141 have good flatness, avoiding the risk of color separation. The display panel 10 also includes a black matrix layer 15. The black matrix layer 15 is located on the side of the touch layer 13 facing away from the driver backplane 11. The black matrix layer 15 has a plurality of light holes H2. The plurality of light holes H2 correspond to the plurality of light-emitting devices 12. The orthographic projections of the light holes H2 on the driver backplane 11 overlap with the orthographic projections of the corresponding light-emitting devices 12 on the driver backplane 11.

[0086] The black matrix layer 15 can be made of a light-shielding material. On the one hand, the black matrix layer 15 can prevent crosstalk between the light of two adjacent light-emitting devices 12. On the other hand, the black matrix layer 15 can also block external ambient light, thereby improving the display effect of the display panel 10. Since the multiple dimming holes H1 correspond to the multiple light-emitting devices 12, and the multiple light-through holes H2 correspond to the multiple light-emitting devices 12, the multiple dimming holes H1 can correspond to the multiple light-through holes H2, and the orthographic projections of the dimming holes H1 on the driver backplane 11 can be located within the orthographic projections of the corresponding light-through holes H2 on the driver backplane 11. This can prevent the black matrix layer 15 from blocking too much light emitted by the light-emitting devices 12, thereby affecting the brightness of the light output.

[0087] The orthographic projection of the second touch electrode layer 132 on the driver backplane 11 lies within the orthographic projection of the black matrix layer 15 on the driver backplane 11. This reduces reflection of ambient light by the second touch electrode layer 133 and lowers reflectivity. Furthermore, the orthographic projection of the first touch electrode layer 131 on the driver backplane 11 also lies within the orthographic projection of the black matrix layer 15 on the driver backplane 11, thereby reducing reflection of ambient light by the first touch electrode layer 131.

[0088] Optionally, the side of the black matrix layer 15 facing the driver backplane 11 contacts the second touch electrode layer 133. The black matrix layer 15 not only reduces forward light reflection from the second touch electrode layer 133 but also provides insulation protection for the second touch electrode layer 133. This eliminates the need for an insulating layer on the side of the second touch electrode layer 133 facing away from the driver backplane 11, thereby reducing one mask and further reducing manufacturing costs. Exemplarily, the material of the black matrix layer 15 may include a black dye, ensuring that the contact between the black matrix layer 15 and the second touch electrode layer 133 does not affect the conductivity of the second touch electrode layer 133.

[0089] Optionally, the display panel 10 may further include a pixel definition layer 16 and an encapsulation layer 17. The pixel definition layer 16 is located between the driver backplane 11 and the touch layer 13. The pixel definition layer 16 has a plurality of pixel openings H3. The plurality of pixel openings H3 correspond one-to-one to the plurality of light-emitting devices 12. At least a portion of the light-emitting device 12 is located within the corresponding pixel opening H3. That is, the pixel definition layer 16 can be used to divide the plurality of light-emitting devices 12. Since the plurality of dimming holes H1 correspond to the plurality of light-emitting devices 12, and the plurality of pixel openings H3 correspond to the plurality of light-emitting devices 12, the plurality of dimming holes H1 can correspond to the plurality of pixel openings H3. The orthographic projection of the pixel opening H3 on the driver backplane 11 can be located within the orthographic projection of the corresponding dimming hole H1 on the driver backplane 11. In this way, the large-angle light emitted by the light-emitting device 12 can also be filtered by the color block 141, and the large-angle light is prevented from being blocked by the black matrix layer 15 and affecting the brightness of the light.

[0090] The encapsulation layer 17 is located between the light-emitting device 12 and the touch layer 13. The encapsulation layer 17 can be used to protect the light-emitting device 12 and prevent external moisture or oxygen from penetrating and corroding the light-emitting device 12. The encapsulation layer 17 can have a laminated structure. For example, the encapsulation layer 17 can include a first inorganic encapsulation layer, an organic encapsulation layer, and a second inorganic encapsulation layer stacked in a direction away from the light-emitting device 12.

[0091] Among them, for the light-through hole H2 and pixel opening H3 corresponding to the same light-emitting device 12, the orthographic projection of the pixel opening H3 on the driving backplane 11 is located within the orthographic projection of the light-through hole H2 on the driving backplane 11, thereby avoiding part of the light from being blocked by the black matrix layer 15, thereby improving the light extraction efficiency.

[0092] Furthermore, in a direction parallel to the drive backplane 11, the distance D4 between the inner wall of the light-through hole H2 and the inner wall of the pixel opening H3 corresponding to the same light-emitting device 12 is less than or equal to 6 microns. Within this range, the black matrix layer 15 can ensure its light-blocking effect, effectively reducing reflectivity and the risk of crosstalk. Furthermore, because the width of the step surface M1 can be greater than or equal to 4.5 microns to prevent peeling, the distance D4 can also be greater than or equal to 4.5 microns, thereby ensuring the light extraction efficiency of the display panel 10.

[0093] For the second implementation, please refer to Figure 7 , Figure 7 This is a schematic diagram of the structure of another display panel provided by an embodiment of the present application. The color resist block 141 includes a main portion 1411 and an edge portion 1412. The main portion 1411 is located within the dimming hole H1, and the edge portion 1412 is located outside the dimming hole H1 and distributed on the side of the second touch electrode layer 133 facing away from the driving backplane 11.

[0094] In the present application, the main body 1411 and the edge 1412 are connected to form an integral structure, and the upper surfaces of the main body 1411 and the edge 1412 facing away from the driving backplane 11 can be flush, thereby improving the flatness of the color resist block 141. In the direction perpendicular to the driving backplane 11, the thickness of the main body 1411 can be greater than the thickness of the touch insulating layer 133, and the thickness of the main body 1411 can be greater than the thickness of the edge 1412. For example, Figure 7 In the display panel shown, the thickness of the edge portion 1412 can be equal to the difference between the thickness of the main body portion 1411 and the thickness of the touch insulation layer 133, so that on the basis of ensuring that the upper surfaces of the main body portion 1411 and the edge portion 141 are flush, the edge portion 141 can cover the second touch electrode layer 133, thereby the edge portion 141 can protect the second touch electrode layer 133.

[0095] For example, in the display panel structure provided by the first exemplary embodiment, the main body 1411 of the first color resist block 141a can be used to filter the light beam emitted by the first light-emitting device 12a. The edge portion 1412 of the first color resist block 141a is stacked with the touch insulation layer 132. Since the first color resist block 141a can block light of colors other than the first color, and the touch insulation layer 132 can block light of colors other than the second and third colors, the stacked edge portion 1412 and touch insulation layer 132 can block these three colors, as well as light of colors other than these three colors. This can block external ambient light and reduce the risk of crosstalk. This achieves the same function as a black matrix layer, reduces one mask, and thus reduces manufacturing costs.

[0096] The orthographic projection of the second touch electrode layer 133 on the driver backplane 11 is located within the orthographic projection of the multiple edge portions 1412 of the multiple color resist blocks 141 on the driver backplane 11. This reduces reflection of ambient light by the second touch electrode layer 133 and lowers reflectivity. Furthermore, the orthographic projection of the first touch electrode layer 131 on the driver backplane 11 is also located within the orthographic projection of the multiple edge portions 1412 of the multiple color resist blocks 141 on the driver backplane 11, thereby reducing reflection of ambient light by the first touch electrode layer 131.

[0097] Optionally, the side of the edge portion 1412 facing the driver backplane 11 contacts the second touch electrode layer 133. The edge portion 1412 not only reduces forward light reflection from the second touch electrode layer 133, but also, because the color resist layer 14 is made of an organic material, provides insulation and protection for the second touch electrode layer 133. This eliminates the need for an insulating layer on the side of the second touch electrode layer 133 facing away from the driver backplane 11, thereby eliminating one mask and reducing manufacturing costs.

[0098] In the second exemplary embodiment, please refer to Figure 8 , Figure 8: This is a schematic diagram of the structure of another display panel provided in an embodiment of the present application. Among the multiple color block blocks 141, some of the color block blocks 141 are first color block blocks 141a, and other color block blocks 141 are second color block blocks 141b. The multiple first color block blocks 141a correspond one-to-one with the multiple first light-emitting devices 12a, and the multiple second color block blocks 141b correspond one-to-one with the multiple second light-emitting devices 12b. Furthermore, the orthographic projection of the first color block 141a on the driver backplane 11 overlaps with the orthographic projection of the corresponding first light-emitting device 12a on the driver backplane 11, and the orthographic projection of the second color block 141b on the driver backplane 11 overlaps with the orthographic projection of the corresponding second light-emitting device 12b on the driver backplane 11. In this way, the multiple color block blocks 141 can filter the light beams emitted by the first light-emitting device 12a and the second light-emitting device 12b, thereby improving the color purity of the light beams emitted by the first light-emitting device 12a and the second light-emitting device 12b.

[0099] The touch insulating layer 132 has a light filtering property, and is used to transmit the third color light and block other colors of light. In other words, the touch insulating layer 132 can be made of a material that has selective transmittance to the third color light, and the material only has a high transmittance to the third color light.

[0100] The orthographic projection of the third light-emitting device 12c on the driver backplane 11 is located within the orthographic projection of the touch insulation layer 132 on the driver backplane 11. This allows the light beam emitted by the third light-emitting device 12c to reach the touch insulation layer 132, which only allows light of the third color to pass through. Therefore, the touch insulation layer 132 can filter the light beam emitted by the third light-emitting device 12c, thereby improving the color purity of the light beam emitted by the third light-emitting device 12c. Furthermore, the display panel 10 does not need to include a color resist block 141 corresponding to the third light-emitting device 12c, thereby saving a mask and reducing manufacturing costs. Regarding external ambient light, the touch insulation layer 132 can also absorb light other than the third color, thereby reducing the reflectivity of the touch insulation layer 132.

[0101] For example, in a second exemplary embodiment, the colors of the first color resist block 141a and the second color resist block 141b can be green and blue, respectively. In this case, the touch insulating layer 132 can transmit red light and block light of other colors. Alternatively, the colors of the first color resist block 141a and the second color resist block 141b can be blue and red, respectively. In this case, the touch insulating layer 132 can transmit green light and block light of other colors. Alternatively, the colors of the first color resist block 141a and the second color resist block 141b can be red and blue, respectively. In this case, the touch insulating layer 132 can transmit green light and block light of other colors.

[0102] For the second exemplary embodiment, two implementation methods can also be used to reduce reflectivity and avoid crosstalk.

[0103] For the first implementation, please refer to Figure 8 A black matrix layer 15 is provided in the display panel. The specific structure of the black matrix layer 15 can refer to the relevant content in the first exemplary embodiment and will not be described in detail here.

[0104] For the second implementation, please refer to Figure 9 , Figure 9 This is a schematic diagram of the structure of another display panel provided by an embodiment of the present application. The color resist block 141 includes a main portion 1411 and an edge portion 1412. The main portion 1411 is located within the dimming hole H1, while the edge portion 1412 is located outside the dimming hole H1 and is distributed on the side of the second touch electrode layer 133 facing away from the driving backplane 11. The orthographic projection of the second touch electrode layer 133 on the driving backplane 11 is located within the orthographic projection of the multiple edge portions 1412 in the multiple color resist blocks 141 on the driving backplane 11.

[0105] In the present application, the main body 1411 and the edge portion 1412 are connected to form an integrated structure, and the upper surfaces of the main body 1411 and the edge portion 1412 facing away from the driver backplane 11 can be flush, thereby improving the flatness of the color resist block 141. In a direction perpendicular to the driver backplane 11, the thickness of the main body 1411 can be greater than the thickness of the touch insulation layer 133, and the thickness of the main body 1411 can be greater than the thickness of the edge portion 1412. This ensures that the upper surfaces of the main body 1411 and the edge portion 141 are flush, and the edge portion 141 can cover the second touch electrode layer 133, thereby protecting the second touch electrode layer 133.

[0106] For example, for the structure of the display panel provided by the second exemplary embodiment, Figure 9 Only one case is shown, that is, the first color resist block 141 a includes a main body portion 1411 and an edge portion 1412 , and the entire second color resist block 141 b is located in the corresponding dimming hole H1 .

[0107] The main portion 1411 of the first color resist block 141a can be used to filter the light beam emitted by the first light-emitting device 12a. The edge portion 1412 of the first color resist block 141a is stacked with the touch insulation layer 132. The second color resist block 141b can be used to filter the light beam emitted by the first light-emitting device 12a. Since the first color resist block 141a can block light of colors other than the first color, and the touch insulation layer 132 can block light of colors other than the third color, the stacked edge portion 1412 and touch insulation layer 132 can block these three colors of light, as well as light of colors other than these three colors. This can block external ambient light and reduce the risk of crosstalk. In other words, it achieves the same function as a black matrix layer, can reduce one mask, and thus reduce manufacturing costs.

[0108] For another case, please refer to Figure 10 , Figure 10 1 is a schematic structural diagram of another display panel provided by an embodiment of the present application. Specifically, a first color resist block 141a includes a main portion 1411 and an edge portion 1412, and a second color resist block 141b also includes a main portion 1411 and an edge portion 1412. For two adjacent first and second color resist blocks 141a, 141b, the edge portion 1412 of the first color resist block 141a and the edge portion 1412 of the second color resist block 141b can be stacked. This can increase the adhesion strength between the first color resist block 141a and the touch insulation layer 132, as well as the adhesion strength between the second color resist block 141b, the touch insulation layer 132, and the first color resist block 141a, thereby preventing the color resist layer 14 from peeling off. In addition, the edge portion 1412 of the first color resist block 141a and the edge portion 1412 of the second color resist block 141b may also be arranged in a non-stacked manner. For example, in a direction parallel to the driving backplane 11, the edge portion 1412 of the second color resist block 141b may be located between the main body 1411 of the first color resist block 141a and the second color resist block 141b. This application does not impose any restrictions on this.

[0109] In addition, the present application may also provide a portion of the plurality of first color resist blocks 141a including: a main body portion 1411 and an edge portion 1412, and another portion of the first color resist blocks 141a are all located in the corresponding dimming hole H1; a portion of the plurality of second color resist blocks 141b include: a main body portion 1411 and an edge portion 1412, and another portion of the second color resist blocks 141b are all located in the corresponding dimming hole H1. For details, please refer to Figure 9 The illustrated embodiments are not described in detail here.

[0110] In the third exemplary embodiment, please refer to Figure 5Among the plurality of color block blocks 141 , a portion of the color block blocks 141 is a first color block 141 a , another portion of the color block blocks 141 is a second color block 141 b , and another portion of the color block blocks 141 is a plurality of third color block blocks 141 c .

[0111] The plurality of first color resist blocks 141a correspond one-to-one to the plurality of first light-emitting devices 12a, the plurality of second color resist blocks 141b correspond one-to-one to the plurality of second light-emitting devices 12b, and the plurality of third color resist blocks 141c correspond one-to-one to the plurality of third light-emitting devices 12c. Furthermore, the orthographic projections of the first color resist blocks 141a on the driver backplane 11 overlap with the orthographic projections of the corresponding first light-emitting devices 12a on the driver backplane 11, the orthographic projections of the second color resist blocks 141b on the driver backplane 11 overlap with the orthographic projections of the corresponding second light-emitting devices 12b on the driver backplane 11, and the orthographic projections of the third color resist blocks 141c on the driver backplane 11 overlap with the orthographic projections of the corresponding third light-emitting devices 12c on the driver backplane 11.

[0112] For the third exemplary embodiment, two implementation methods can also be used to reduce reflectivity and avoid crosstalk.

[0113] For the first implementation, please refer to Figure 5 A black matrix layer 15 is provided in the display panel. The specific structure of the black matrix layer 15 can refer to the relevant content in the first exemplary embodiment and will not be described in detail here.

[0114] For the second implementation, please refer to Figure 11 , Figure 11 This is a schematic diagram of the structure of another display panel provided by an embodiment of the present application. The color resist block 141 includes a main portion 1411 and an edge portion 1412. The main portion 1411 is located within the dimming hole H1, while the edge portion 1412 is located outside the dimming hole H1 and is distributed on the side of the second touch electrode layer 133 facing away from the driving backplane 11. The orthographic projection of the second touch electrode layer 133 on the driving backplane 11 is located within the orthographic projection of the multiple edge portions 1412 in the multiple color resist blocks 141 on the driving backplane 11.

[0115] In the present application, the main body 1411 and the edge portion 1412 are connected to form an integrated structure, and the upper surfaces of the main body 1411 and the edge portion 1412 facing away from the driver backplane 11 can be flush, thereby improving the flatness of the color resist block 141. In a direction perpendicular to the driver backplane 11, the thickness of the main body 1411 can be greater than the thickness of the touch insulation layer 133, and the thickness of the main body 1411 can be greater than the thickness of the edge portion 1412. This ensures that the upper surfaces of the main body 1411 and the edge portion 141 are flush, and the edge portion 141 can cover the second touch electrode layer 133, thereby protecting the second touch electrode layer 133.

[0116] For example, for the structure of the display panel provided by the third exemplary embodiment, Figure 11 Only one scenario is shown, where two adjacent color resist blocks 141 are respectively a first color resist block 141a and a second color resist block 141b. In the region between the main portion 1411 of the first color resist block 141a and the main portion 1411 of the second color resist block 141b, the edge portion 1412 of the first color resist block 141a and the edge portion 1412 of the second color resist block 141b are stacked. Because the first color resist block 141a can block light of colors other than the first color, and the second color resist block 141b can block light of colors other than the second color, the stacked edge portions 1412 of the first color resist block 141a and the edge portions 1412 of the second color resist block 141b can block these three colors of light, as well as light of colors other than these three colors. This can block ambient light and reduce the risk of crosstalk, achieving the same function as a black matrix layer, eliminating one mask, and thus reducing manufacturing costs.

[0117] Furthermore, at least two of the first, second, and third color resist blocks 141a, 141b, and 141c include a main portion 1411 and an edge portion 1412. For example, two color resist blocks may include a main portion 1411 and an edge portion 1412, while another color resist block may be entirely located within the corresponding dimming hole H1. Alternatively, all three color resist blocks may include a main portion 1411 and an edge portion 1412.

[0118] The present application can also set the edge portions 1412 of any two of the three color blocks to overlap, or set the edge portions 1412 of the three color blocks to overlap to replace the black matrix layer. For details, please refer to Figure 11 The illustrated embodiments are not described in detail here.

[0119] In summary, in the display panel provided by the embodiments of the present application, the touch insulating layer has multiple dimming holes. By providing multiple color resist blocks corresponding to the multiple dimming holes, and the multiple dimming holes corresponding to the multiple light-emitting devices, the multiple color resist blocks can correspond to the multiple light-emitting devices, thereby enabling the color resist blocks to filter light for the corresponding light-emitting devices. Furthermore, by disposing at least a portion of the color resist blocks within the corresponding dimming holes, the thickness of the display panel can be reduced, thereby achieving a thinner and lighter display panel.

[0120] On the other hand, an embodiment of the present application further provides a display device, which includes a power supply component and a display panel provided by any of the above embodiments.

[0121] Since the display device includes the display panel provided by the above embodiment, the display device can also have a similar effect, that is, the thickness of the display device can be reduced.

[0122] In this application, the term "at least one of A and B" simply describes an association relationship between associated objects, indicating that three possible relationships exist. For example, "at least one of A and B" can mean: A exists alone, A and B exist simultaneously, and B exists alone. Similarly, "at least one of A, B, and C" means that seven possible relationships exist, indicating: A exists alone, B exists alone, C exists alone, A and B exist simultaneously, A and C exist simultaneously, C and B exist simultaneously, and A, B, and C exist simultaneously.

[0123] It should be noted that in the accompanying drawings, the sizes of layers and regions may be exaggerated for clarity of illustration. It will also be understood that when an element or layer is referred to as being "on" another element or layer, it may be directly on the other element, or there may be an intermediate layer. In addition, it will be understood that when an element or layer is referred to as being "under" another element or layer, it may be directly under the other element, or there may be more than one intermediate layer or element. In addition, it will also be understood that when a layer or element is referred to as being "between" two layers or elements, it may be the only layer between the two layers or elements, or there may also be more than one intermediate layer or element. Similar reference numerals throughout the text indicate similar elements.

[0124] In this application, the terms "first", "second", "third" and "fourth" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more, unless otherwise expressly limited.

[0125] The above description is merely an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
