Description

Display panel and display device

[0001] This disclosure claims priority to Chinese Patent Application No. 202411535222.3, filed on October 30, 2024, entitled “Display Panel and Display Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of display technology, and in particular to a display panel and display device. Background Technology

[0003] A display panel is a device used to display images and text.

[0004] In some current display panels, the effect of integrated display and touch is achieved by integrating touch functions. Therefore, in addition to the structure used to realize the display function, a film layer used to realize the touch function is added to the display panel.

[0005] However, the aforementioned film layer used to achieve touch functionality increases the thickness of the display panel, resulting in poor performance in achieving a thinner and lighter display panel. Summary of the Invention

[0053] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0054] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0055] Figure 1 is a schematic diagram of a display panel 20 provided by related technology. The display panel 20 includes: a driving backplate 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 along a direction away from the driving backplate 21. The light-emitting device 22 can be used to emit a large amount of light. However, for large-angle light, such as light rays L1 and L2, the black matrix layer 25 will block the light emitted by the light-emitting device 22, causing some of the light to be lost, resulting in a low forward light emission efficiency of the display panel 20.

[0056] In addition, the color resist layer 24 needs to cover the edge of the black matrix layer 25 to prevent the color resist layer 24 from peeling off. However, at the contact point between the color resist layer 24 and the black matrix layer 25, the flatness of the color resist layer 24 is poor, which easily leads to light reflection and unevenness, thus causing color separation.

[0057] This application provides a display panel. Please refer to Figure 2, which is a schematic diagram of the structure of a display panel provided in this application embodiment. The display panel 10 includes: a driving backplate 11, a light-emitting device 12, a touch layer 13, and a color resist layer 14. Here, the display panel 10 can be an organic light-emitting diode (OLED) display panel. OLED display panels have many advantages such as self-illumination, low driving voltage, high luminous efficiency, short response time, high clarity and contrast, wide operating temperature range, and the ability to achieve flexible display and large-area full-color display.

[0058] There are multiple light-emitting devices 12, all located on the same side of the driving backplate 11. Here, the driving backplate 11 supports other film layers in the display panel 10, and includes a thin-film transistor (TFT) array. The light-emitting devices 12 emit light beams in a direction away from the driving backplate 11. Each of the multiple light-emitting devices 12 can be electrically connected to the TFTs in the driving backplate 11, thus allowing the driving backplate 11 to control the light-emitting state and brightness of each light-emitting device 12. For example, the light-emitting device 12 can be an organic light-emitting diode (OLED), and may include a first electrode, an organic light-emitting layer, and a second electrode stacked together, with the first and second electrodes cooperating to drive the organic light-emitting layer to emit light.

[0059] The touch layer 13 is located on the side of the plurality of light-emitting devices 12 away from the driving back plate 11. The touch layer 13 includes a first touch electrode layer 131, a touch insulating layer 132 and a second touch electrode layer 133 stacked along the direction away from the driving back plate 11. The touch insulating layer 132 has a plurality of dimming holes H1, which correspond to the plurality of light-emitting devices 12. The orthographic projection of the dimming hole H1 on the driving back plate 11 overlaps with the orthographic projection of the corresponding light-emitting device 12 on the driving back plate 11.

[0060] Here, the touch layer 13 can employ Flexible Multi Layer On Cell (FMLOC) technology, which integrates the touch layer 13 into the display panel 10 using a patterning process, thereby achieving integrated display and touch functionality. The first touch electrode layer 131 and the second touch electrode layer 133 can include self-capacitive or mutual-capacitive structures. When a user's finger contacts the touch electrodes, the capacitance value in the self-capacitive or mutual-capacitive structures changes to determine the location of the touch, thus enabling the display panel 10 to perform touch functionality. The touch insulating layer 132 provides insulation between the first touch electrode layer 131 and the second touch electrode layer 133. Multiple dimming holes H1 in the touch insulating layer 132 can accommodate multiple color resist blocks 141, thereby reducing the thickness of the display panel 10. For example, the material of the touch insulating layer 132 may include organic materials. For instance, 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.

[0061] The color resist layer 14 is located on the side of the plurality of light-emitting devices 12 away from the driving back plate 11. The color resist layer 14 includes a plurality of color resist blocks 141, the plurality of color resist blocks 141 corresponding to a plurality of dimming holes H1, and at least a portion of the color resist blocks 141 being located within the corresponding dimming holes H1.

[0062] Here, the color resist layer 14 can employ color filter on encapsulation (COE) technology. COE technology replaces the polarizer by manufacturing the color resist layer 14, achieving the effect of reducing the thickness of the display panel 10 and improving brightness. Since multiple color resist blocks 141 correspond to multiple dimming holes H1, and multiple dimming holes H1 correspond to multiple light-emitting devices 12, the multiple color resist blocks 141 can correspond to multiple light-emitting devices 12, so that the orthographic projection of the color resist block 141 on the driving backplate 11 overlaps with the orthographic projection of the corresponding light-emitting device 12 on the driving backplate 11. In this way, the light emitted from each light-emitting device 12 can pass through the corresponding color resist block 141 before exiting. During the process of the light emitted from the light-emitting device 12 passing through the corresponding color resist block 141, the color resist block 141 can transmit specific colors of light emitted by the light-emitting device 12 while filtering out other colors, thereby ensuring good color accuracy of the display panel 10 during image display.

[0063] Furthermore, for natural light incident from the light-emitting side, it first enters the display panel through the color resist layer 14. The color resist layer 14, which can only transmit a single color of light, can filter out most of the light. A small portion of the light entering the display panel will lose some light when reflected by the metal material and the microcavity of the light-emitting device 12 inside the display panel. When the reflected light exits through the color resist layer 14, it will pass through the filtering effect of the color resist layer 14 again, further reducing the intensity of the outgoing reflected light, thereby reducing the reflectivity.

[0064] It should be noted that at least a portion of the color resist block 141 is located within the corresponding dimming hole H1, including various cases. Figure 2 only shows the case where the entire color resist block 141 is located within the corresponding dimming hole H1, which can improve the flatness of the color resist block 141, but this 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, and another portion of the color resist block 141 can be located outside the corresponding dimming hole H1. Since the materials of the color resist block 141 and the touch insulating layer 132 can both be organic materials, by setting the color resist block 141 to fill the corresponding dimming hole H1, the color resist block 141 and the touch insulating layer 132 can form a whole-layer structure, thereby effectively improving the strength of the touch insulating layer 132, thus ensuring the strength of the display panel 10.

[0065] In summary, the display panel provided in this application embodiment has a touch insulating layer with multiple dimming holes. By setting multiple color resist blocks corresponding to multiple dimming holes, and multiple dimming holes corresponding to multiple light-emitting devices, the multiple color resist blocks can correspond to multiple light-emitting devices, thereby enabling the color resist blocks to filter light for their respective light-emitting devices. Furthermore, by placing at least a portion of the color resist blocks within the corresponding dimming holes, the thickness of the display panel can be reduced, thus achieving a thinner and lighter display panel.

[0066] Optionally, referring 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 that of the touch insulating layer 132. Here, for large-angle light emitted by the light-emitting device 12, for example, light rays L3 and L4 reaching the interface between the color resist block 141 and the touch insulating layer 132, the difference in refractive index between the color resist block 141 and the touch insulating layer 132 can achieve a forward light extraction effect. That is, light rays L3 and L4 can be deflected at the interface in a direction perpendicular to the driving backplate 10, which can avoid the loss of large-angle light, thereby improving the forward light extraction efficiency and brightness of the display panel 10. For example, 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.

[0067] The structure of the dimming aperture is explained below:

[0068] The structure of the dimming aperture provided in this application is shown in Figure 2. The inner wall of the dimming aperture H1 is sloping, and the angle between the inner wall of the dimming aperture H1 and the plane where the lower opening of the dimming aperture H1 is located is an obtuse angle, which facilitates the forward light extraction of large-angle light. When the inner wall of the dimming aperture H1 includes only one slope, the shape of the cross section of the dimming aperture H1 perpendicular to the drive back plate 11 can be an inverted trapezoid, which facilitates manufacturing. The inner wall of the dimming aperture H1 can also include multiple continuous slopes, and the angle between each slope and the plane where the lower opening of the dimming aperture H1 is located can be different. Multiple slopes can also achieve a forward light extraction effect. However, there is still a risk of the color resist 141 peeling off at the inner wall of the dimming aperture H1. This application can arrange the color resist 141 to contact the upper surface of the touch insulating layer 132 to avoid peeling off.

[0069] This application embodiment also provides another structure for the dimming hole, namely, the inner wall of the dimming hole can have a stepped structure to prevent the color resist from peeling off. Please refer to Figure 3, which is a schematic diagram of another display panel structure provided in this application embodiment. At least part of the dimming hole H1 includes: a first sub-via H11, and a second sub-via H12 communicating with the first sub-via H11. The first sub-via H11 is closer to the driving backplate 11 than the second sub-via H12.

[0070] The first sub-via H11 has a first opening K1 on the side facing away from the drive backplate 11, and the second sub-via H12 has a second opening K2 on the side facing the drive 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 drive backplate 11 lies within the orthographic projection of the second opening K2 on the drive backplate 11, forming a stepped surface M1 between the first opening K1 and the second opening K2. Here, the stepped 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 stepped surface M1 can be parallel to the drive backplate 11 to increase the bonding strength between the color resist block 141 and the touch insulating layer 132. Due to manufacturing errors, this application does not strictly require the stepped surface M1 to be absolutely parallel to the drive backplate 11. For example, "parallel" can refer to approximately parallel with a deviation range of less than 5 degrees.

[0071] Among them, the portion of the color block 141 located inside the dimming hole H1 is in contact with the inner wall M2 of the first sub-via H11 and the inner wall M3 of the second sub-via H12, and is in contact with the step surface M1.

[0072] Thus, at the stepped surface M1, the bonding strength between the color resist block 141 and the touch insulating layer 132 is relatively high, thereby reducing the risk of the color resist block 141 peeling off. Therefore, it is unnecessary to ensure that the color resist block contacts the upper surface of the touch insulating layer 132, thus effectively improving the flatness of the color resist block 141 while ensuring it does not peel off. However, this application is not limited to this. For the structure of the dimming hole H1 shown in Figure 3, the color resist block 141 can also contact the upper surface of the touch insulating layer 132, which further ensures that the color resist block 141 adheres to the touch insulating layer 132.

[0073] Optionally, please refer to Figures 3 and 4. Figure 4 is an enlarged schematic diagram of a portion of the structure in the display panel shown in Figure 3. The first sub-via H11 has a third opening K3 on the side facing the drive backplate 11. The angle α1 between the plane containing the third opening K3 and the inner wall M2 of the first sub-via H11 is an obtuse angle. Furthermore, the angle α2 between the stepped surface M1 and the inner wall M3 of the second sub-via H12 is also an obtuse angle. This ensures that large-angle light can be captured in the forward direction, reducing light loss at large angles. For example, the range of angles α1 and α2 can be 105 degrees to 150 degrees. Moreover, the smaller the angles α1 and α2, the more the large-angle light is directed in the forward direction, resulting in better forward light capture for large-angle light.

[0074] Optionally, in the direction parallel to the drive backplate 11, the width D1 of the stepped surface M1 is greater than or equal to 4.5 micrometers. Within this range, the width D1 ensures effective overlap between the color resist 141 and the touch insulating layer 132, thereby preventing the color resist 141 from peeling off.

[0075] Optionally, the second sub-via H12 has a fourth opening K4 on the side facing away from the drive backplate 11. In the direction perpendicular to the drive backplate 11, the distance D2 between the stepped surface M1 and the surface containing the third opening K3 ranges from 1.2 micrometers to 2 micrometers, and the distance D3 between the stepped surface M1 and the surface containing the fourth opening K4 ranges from 1.5 micrometers to 2 micrometers. Distances D2 and D3 falling within this range not only facilitate the fabrication of the dimming hole H1, but also prevent the first sub-via H11 and the second sub-via H12 from being too deep, which could lead to material residue in the color resist block 141, and prevent the touch insulating layer 132 from being too thick, thus affecting light transmittance.

[0076] In this application, a stepped structure of the inner wall of the dimming aperture H1 can be achieved using a halftone mask. For example, after forming the entire touch insulating layer 132, a halftone mask can be used to expose and develop the touch insulating layer 132. Since the halftone mask includes multiple regions with different transmittances, the halftone mask can control the degree of light transmission to achieve different levels of exposure for multiple regions, thereby adjusting the depth of the first sub-via H11 and the second sub-via H12, thus forming multiple dimming apertures H1 with stepped inner walls.

[0077] It should be noted that, due to manufacturing process errors, the embodiments of this application do not strictly require the inner wall of the dimming hole H1 to be flat. For example, the inner wall of the dimming hole H1 can also be curved, thus achieving the effect of forward light extraction.

[0078] This application provides another display panel. Please refer to Figure 5, which is a schematic diagram of the structure of another display panel provided in this application embodiment. 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 emit light of a first color, the second light-emitting devices 12b emit light of a second color, and the third light-emitting devices 12c 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 yet another of red, blue, and green.

[0079] The plurality of color resist blocks 141 includes at least one of the following: a first color resist block 141a with a first color, a second color resist block 141b with a second color, and a third color resist block 141c with a third color. That is, the plurality of color resist blocks 141 can be a color resist block 141 of one color, or a color resist block 141 of two colors, or a color resist block 141 of three colors.

[0080] The following describes the types of color resist blocks included in the display panel using three exemplary embodiments:

[0081] In a first exemplary embodiment, please refer to FIG6, which is a schematic diagram of another display panel structure provided in this application embodiment. Multiple color resist blocks 141 are all first color resist blocks 141a, and each of the multiple first color resist blocks 141a corresponds one-to-one with a multiple first light-emitting devices 12a. The orthographic projection of the first color resist block 141a on the driving backplate 11 overlaps with the orthographic projection of the corresponding first light-emitting device 12a on the driving backplate 11. Thus, the multiple color resist blocks 141 can only filter the light beam emitted by the first light-emitting device 12a, thereby improving the color purity of the light beam emitted by the first light-emitting device 12a.

[0082] The touch insulating layer 132 has light-filtering properties, allowing the transmission of second and third color light while blocking other colors of light. That is, the touch insulating layer 132 can be made of a material that selectively transmits the second and third color light, exhibiting high transmittance only for the second and third color light.

[0083] The orthographic projections of the second light-emitting device 12b and the third light-emitting device 12c on the driving backplate 11 are both located within the orthographic projection of the touch insulating layer 132 on the driving backplate 11. Thus, after the light beams emitted by the second and third light-emitting devices 12b and 12c reach the touch insulating layer 132, the touch insulating layer 132 only allows the second and third colors of light to pass through. Therefore, the touch insulating layer 132 can filter 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 have color resist blocks 141 corresponding to the second and third light-emitting devices 12b and 12c, thus saving two masks and reducing manufacturing costs. Regarding ambient light, the touch insulating layer 132 can also absorb light other than the second and third colors, thus reducing reflectivity.

[0084] For example, in a first exemplary embodiment, the first color blocking block 141a can be green, in which case the touch insulating layer 132 can transmit red and blue light while blocking other colors of light. Alternatively, the first color blocking block 141a can be blue, in which case the touch insulating layer 132 can transmit red and green light while blocking other colors of light. Alternatively, the first color blocking block 141a can be red, in which case the touch insulating layer 132 can transmit blue and green light while blocking other colors of light.

[0085] Since the second touch electrode layer 133 is made of metal, it may reflect ambient light, affecting the display effect of the display panel 10. Furthermore, there may be a risk of crosstalk between adjacent light-emitting devices 12. In this application, various implementation methods can be used to reduce reflectivity and avoid crosstalk. The following describes two implementation methods using a first exemplary embodiment as an example:

[0086] In the first embodiment, please refer to Figure 6. All color resist blocks 141 are located within their corresponding dimming holes H1. Therefore, the color resist blocks 141 do not overlap with the black matrix layer 15, nor with the upper surface of the touch insulating layer 132. Consequently, the flatness of the color resist blocks 141 is good, avoiding the risk of color separation. The display panel 10 also includes a black matrix layer 15, located on the side of the touch layer 13 away from the driving backplate 11. The black matrix layer 15 has multiple light-transmitting holes H2, each corresponding to a multiple light-emitting device 12. The orthographic projection of the light-transmitting hole H2 onto the driving backplate 11 overlaps with the orthographic projection of the corresponding light-emitting device 12 onto the driving backplate 11.

[0087] 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 emitted by two adjacent light-emitting devices 12. On the other hand, the black matrix layer 15 can also block ambient light, thereby improving the display effect of the display panel 10. Since multiple dimming holes H1 correspond to multiple light-emitting devices 12, and multiple light-transmitting holes H2 correspond to multiple light-emitting devices 12, the multiple dimming holes H1 can correspond to the multiple light-transmitting holes H2. The orthographic projection of the dimming hole H1 on the driving backplate 11 can be located within the orthographic projection of the corresponding light-transmitting hole H2 on the driving backplate 11. This can prevent the black matrix layer 15 from blocking too much light emitted by the light-emitting devices 12, thus affecting the brightness of the emitted light.

[0088] The orthographic projection of the second touch electrode layer 132 onto the driving backplate 11 lies within the orthographic projection of the black matrix layer 15 onto the driving backplate 11. This reduces the reflection of ambient light by the second touch electrode layer 133, thus lowering its reflectivity. Furthermore, the orthographic projection of the first touch electrode layer 131 onto the driving backplate 11 also lies within the orthographic projection of the black matrix layer 15 onto the driving backplate 11, further reducing the reflection of ambient light by the first touch electrode layer 131.

[0089] Optionally, the black matrix layer 15 contacts the second touch electrode layer 133 on the side facing the driving backplate 11. The black matrix layer 15 not only reduces the forward reflection of the second touch electrode layer 133 but also provides insulation protection, eliminating the need for an insulating layer on the side of the second touch electrode layer 133 facing away from the driving backplate 11. This reduces the need for a mask and lowers manufacturing costs. For example, the material of the black matrix layer 15 may include 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.

[0090] 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 driving backplane 11 and the touch layer 13. The pixel definition layer 16 has multiple pixel openings H3, and each pixel opening H3 corresponds to a multiple light-emitting device 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 multiple light-emitting devices 12. Since multiple dimming holes H1 correspond to multiple light-emitting devices 12, and multiple pixel openings H3 correspond to multiple light-emitting devices 12, the multiple dimming holes H1 can correspond to the multiple pixel openings H3. The orthographic projection of the pixel opening H3 on the driving backplane 11 can be located within the orthographic projection of the corresponding dimming hole H1 on the driving backplane 11. This allows the large-angle light emitted by the light-emitting device 12 to be filtered by the color resist block 141, and prevents the large-angle light from being blocked by the black matrix layer 15, thus affecting the output brightness.

[0091] 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 be a stacked structure. For example, the encapsulation layer 17 may 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.

[0092] Among them, for the same light-emitting device 12, the orthographic projection of the pixel opening H3 on the driving back plate 11 is located within the orthographic projection of the light-emitting hole H2 on the driving back plate 11, thereby avoiding some light being blocked by the black matrix layer 15, and thus improving the light output efficiency.

[0093] Furthermore, in the direction parallel to the driving backplate 11, the distance D4 between the inner wall of the light-transmitting hole H2 corresponding to the same light-emitting device 12 and the inner wall of the pixel opening H3 is less than or equal to 6 micrometers. Within this range, the light-blocking effect of the black matrix layer 15 can be ensured, effectively reducing reflectivity and the risk of crosstalk. Additionally, since the width of the stepped surface M1 can be greater than or equal to 4.5 micrometers to prevent peeling, the distance D4 can also be greater than or equal to 4.5 micrometers, thereby ensuring the light-emitting efficiency of the display panel 10.

[0094] For the second embodiment, please refer to Figure 7, which is a schematic diagram of another display panel structure provided in this application embodiment. The color resist block 141 includes a main body 1411 and an edge portion 1412. The main body 1411 is located inside the dimming hole H1, and the edge portion 1412 is located outside the dimming hole H1 and is distributed on the side of the second touch electrode layer 133 away from the driving back plate 11.

[0095] In this application, the main body 1411 and the edge portion 1412 are connected to form an integral structure, and the upper surfaces of the main body 1411 and the edge portion 1412 facing away from the driving back plate 11 can be flush, thereby improving the flatness of the color resist 141. In the direction perpendicular to the driving back plate 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 portion 1412. For example, in the display panel shown in FIG7, the thickness of the edge portion 1412 can be equal to the difference between the thickness of the main body 1411 and the thickness of the touch insulating layer 133, so that while ensuring that the upper surfaces of the main body 1411 and the edge portion 141 are flush, the edge portion 141 can cover the second touch electrode layer 133, thereby protecting the second touch electrode layer 133.

[0096] For example, in the structure of the display panel provided in 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 insulating layer 132. Since the first color resist block 141a can block light of colors other than the first color, and the touch insulating layer 132 can block light of colors other than the second and third colors, the stacked edge portion 1412 and the touch insulating layer 132 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, thus achieving the same function as the black matrix layer. It can reduce one mask and thus reduce manufacturing costs.

[0097] The orthographic projection of the second touch electrode layer 133 onto the driving back plate 11 lies within the orthographic projection of the edges 1412 of the multiple color resist blocks 141 onto the driving back plate 11. This reduces the reflection of ambient light by the second touch electrode layer 133, thus lowering its reflectivity. Furthermore, the orthographic projection of the first touch electrode layer 131 onto the driving back plate 11 also lies within the orthographic projection of the edges 1412 of the multiple color resist blocks 141 onto the driving back plate 11, thereby reducing the reflection of ambient light by the first touch electrode layer 131.

[0098] Optionally, the edge portion 1412 faces the driving backplate 11 and contacts the second touch electrode layer 133. The edge portion 1412 can not only reduce the forward reflection of the second touch electrode layer 133, but also provide insulation protection for the second touch electrode layer 133 since the color resist layer 14 is made of organic material. Therefore, there is no need to provide an insulating layer on the side of the second touch electrode layer 133 away from the driving backplate 11, thereby reducing the number of masks and thus reducing manufacturing costs.

[0099] In the second embodiment, please refer to FIG8, which is a schematic diagram of another display panel structure provided in this application embodiment. A portion of the multiple color resist blocks 141 are first color resist blocks 141a, and another portion are second color resist blocks 141b. The multiple first color resist blocks 141a correspond one-to-one with the multiple first light-emitting devices 12a, and the multiple second color resist blocks 141b correspond one-to-one with the multiple second light-emitting devices 12b. Furthermore, the orthographic projection of the first color resist block 141a on the driving backplate 11 overlaps with the orthographic projection of the corresponding first light-emitting device 12a on the driving backplate 11, and the orthographic projection of the second color resist block 141b on the driving backplate 11 overlaps with the orthographic projection of the corresponding second light-emitting device 12b on the driving backplate 11. Thus, the multiple color resist blocks 141 can filter the light beams emitted by the first light-emitting devices 12a and 12b, thereby improving the color purity of the light beams emitted by the first light-emitting devices 12a and 12b.

[0100] The touch insulating layer 132 has light-filtering properties, allowing the transmission of a third color of light while blocking other colors of light. That is, the touch insulating layer 132 can be made of a material that selectively transmits the third color of light, exhibiting a high transmittance only for the third color of light.

[0101] The orthographic projection of the third light-emitting device 12c onto the driving backplate 11 lies within the orthographic projection of the touch insulating layer 132 onto the driving backplate 11. This allows the light beam emitted by the third light-emitting device 12c to reach the touch insulating layer 132, and since the touch insulating layer 132 only allows the third color light to pass through, it can filter the light beam emitted by the third light-emitting device 12c, thereby improving the color purity of the light beam. Furthermore, the display panel 10 does not need to have a corresponding color resist block 141 for the third light-emitting device 12c, thus saving a mask and reducing manufacturing costs. The touch insulating layer 132 can also absorb ambient light other than the third color light, thus reducing its reflectivity.

[0102] For example, in a second embodiment, the colors of the first color resist 141a and the second color resist 141b can be green and blue, respectively. In this case, the touch insulating layer 132 can transmit red light and block other colors of light. Alternatively, the colors of the first color resist 141a and the second color resist 141b can be blue and red, respectively. In this case, the touch insulating layer 132 can transmit green light and block other colors of light. Alternatively, the colors of the first color resist 141a and the second color resist 141b can be red and blue, respectively. In this case, the touch insulating layer 132 can transmit green light and block other colors of light.

[0103] For the second exemplary embodiment, two implementation methods can also be used to reduce reflectivity and avoid crosstalk.

[0104] For the first implementation method, 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 be referred to the relevant content in the first exemplary embodiment, and will not be elaborated here.

[0105] The second embodiment is illustrated in Figure 9, which is a schematic diagram of another display panel structure provided in this application embodiment. The color resist block 141 includes a main body 1411 and an edge portion 1412. The main body 1411 is located inside 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 opposite to the driving back plate 11. The orthographic projection of the second touch electrode layer 133 onto the driving back plate 11 lies within the orthographic projection of the multiple edge portions 1412 of the multiple color resist blocks 141 onto the driving back plate 11.

[0106] In this application, the main body 1411 and the edge portion 1412 are connected to form an integral structure, and the upper surfaces of the main body 1411 and the edge portion 1412 facing away from the drive back plate 11 can be flush, thereby improving the flatness of the color resist block 141. In the direction perpendicular to the drive back plate 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 portion 1412, so that while ensuring that the upper surfaces of the main body 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.

[0107] For example, in the structure of the display panel provided in the second exemplary embodiment, FIG9 only shows one case, that is, the first color block 141a includes: a main body portion 1411 and an edge portion 1412, and the entire second color block 141b is located within the corresponding dimming hole H1.

[0108] The main body 1411 of the first color resist 141a can be used to filter the light beam emitted by the first light-emitting device 12a, and the edge portion 1412 of the first color resist 141a is stacked with the touch insulating layer 132. The second color resist 141b can be used to filter the light beam emitted by the first light-emitting device 12a. Since the first color resist 141a can block light of colors other than the first color, and the touch insulating layer 132 can block light of colors other than the third color, the stacked edge portion 1412 and the touch insulating layer 132 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, thus achieving the same function as the black matrix layer. This reduces the number of masks and thus reduces manufacturing costs.

[0109] In another scenario, please refer to Figure 10, which is a schematic diagram of another display panel structure provided in an embodiment of this application. The first color resist block 141a includes a main body portion 1411 and an edge portion 1412, and the second color resist block 141b also includes a main body portion 1411 and an edge portion 1412. For two adjacent first color resist blocks 141a and second color resist blocks 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 increases the adhesion strength between the first color resist block 141a and the touch insulating layer 132, and also increases the adhesion strength between the second color resist block 141b and the touch insulating 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 block 141a and the edge portion 1412 of the second color block 141b may not be stacked. For example, in the direction parallel to the drive back plate 11, the edge portion 1412 of the second color block 141b may be located between the main body portion 1411 of the first color block 141a and the second color block 141b. This application does not limit this.

[0110] Alternatively, this application may also provide a plurality of first color blocks 141a, some of which include a main body 1411 and an edge portion 1412, while the entire portion of the first color blocks 141a is located within the corresponding dimming aperture H1; and a plurality of second color blocks 141b, some of which include a main body 1411 and an edge portion 1412, while the entire portion of the second color blocks 141b is located within the corresponding dimming aperture H1. For details, please refer to the embodiment shown in FIG9, which will not be elaborated further here.

[0111] In the third embodiment, referring to FIG5, a portion of the multiple color resist blocks 141 are first color resist blocks 141a, another portion of the color resist blocks 141 are second color resist blocks 141b, and yet another portion of the color resist blocks 141 are multiple third color resist blocks 141c.

[0112] Multiple first color resist blocks 141a correspond one-to-one with multiple first light-emitting devices 12a, multiple second color resist blocks 141b correspond one-to-one with multiple second light-emitting devices 12b, and multiple third color resist blocks 141c correspond one-to-one with multiple third light-emitting devices 12c. Furthermore, the orthographic projection of the first color resist block 141a on the driving backplate 11 overlaps with the orthographic projection of the corresponding first light-emitting device 12a on the driving backplate 11; the orthographic projection of the second color resist block 141b on the driving backplate 11 overlaps with the orthographic projection of the corresponding second light-emitting device 12b on the driving backplate 11; and the orthographic projection of the third color resist block 141c on the driving backplate 11 overlaps with the orthographic projection of the corresponding third light-emitting device 12c on the driving backplate 11.

[0113] For the third exemplary embodiment, two implementation methods can also be used to reduce reflectivity and avoid crosstalk.

[0114] For the first implementation method, 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 be referred to the relevant content in the first exemplary embodiment, and will not be elaborated here.

[0115] The second embodiment is illustrated in Figure 11, which is a schematic diagram of another display panel structure provided in this application embodiment. The color resist block 141 includes a main body 1411 and an edge portion 1412. The main body 1411 is located inside 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 opposite to the driving back plate 11. The orthographic projection of the second touch electrode layer 133 onto the driving back plate 11 lies within the orthographic projection of the multiple edge portions 1412 of the multiple color resist blocks 141 onto the driving back plate 11.

[0116] In this application, the main body 1411 and the edge portion 1412 are connected to form an integral structure, and the upper surfaces of the main body 1411 and the edge portion 1412 facing away from the drive back plate 11 can be flush, thereby improving the flatness of the color resist block 141. In the direction perpendicular to the drive back plate 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 portion 1412, so that while ensuring that the upper surfaces of the main body 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.

[0117] For example, in the structure of the display panel provided in the third exemplary embodiment, FIG11 only shows one case, that is, when the two adjacent color resist blocks 141 are the first color resist block 141a and the second color resist block 141b respectively, in the region between the main body portion 1411 in the first color resist block 141a and the main body portion 1411 in the second color resist block 141b, the edge portion 1412 in the first color resist block 141a and the edge portion 1412 in the second color resist block 141b are stacked. Since the first color block 141a can block light of colors other than the first color, and the second color block 141b can block light of colors other than the second color, the edge portions 1412 of the stacked first color block 141a and the edge portions 1412 of the second color block 141b can block these three colors of light, as well as light of colors other than these three colors of light. This can block ambient light and reduce the risk of crosstalk, thus achieving the same function as the black matrix layer. It can reduce the number of masks and thus reduce manufacturing costs.

[0118] Furthermore, at least two of the first color resist 141a, the second color resist 141b, and the third color resist 141c include a main body portion 1411 and an edge portion 1412. For example, two color resists include a main body portion 1411 and an edge portion 1412, while the entire other color resist is located within the corresponding dimming aperture H1. Alternatively, all three color resists include a main body portion 1411 and an edge portion 1412.

[0119] This application can also set the edge portions 1412 of any two of the three color resist blocks to be superimposed, or set the edge portions 1412 of the three color resist blocks to be superimposed to replace the black matrix layer. For details, please refer to the embodiment shown in FIG11, which will not be elaborated here.

[0120] In summary, the display panel provided in this application embodiment has a touch insulating layer with multiple dimming holes. By setting multiple color resist blocks corresponding to multiple dimming holes, and multiple dimming holes corresponding to multiple light-emitting devices, the multiple color resist blocks can correspond to multiple light-emitting devices, thereby enabling the color resist blocks to filter light for their respective light-emitting devices. Furthermore, by placing at least a portion of the color resist blocks within the corresponding dimming holes, the thickness of the display panel can be reduced, thus achieving a thinner and lighter display panel.

[0121] On the other hand, this application also provides a display device, which includes a power supply assembly and a display panel provided in any of the above embodiments.

[0122] Since the display device includes the display panel provided in the above embodiments, the display device can also have a similar effect, that is, the thickness of the display device can be reduced.

[0123] In this application, the term "at least one of A and B" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, "at least one of A and B" can represent three cases: A exists alone, A and B exist simultaneously, and B exists alone. Similarly, "at least one of A, B, and C" indicates that seven relationships can exist, representing seven cases: 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.

Furthermore, it is understood that when an element or layer is referred to as being "on" another element or layer, it can be directly on the other element, or there may be intermediate layers. Additionally, it is understood that when an element or layer is referred to as being "below" another element or layer, it can be directly below the other element, or there may be more than one intermediate layer or element. Furthermore, it is also understood that when a layer or element is referred to as being "between" two layers or two elements, it can be the only layer between the two layers or two elements, or there may be more than one intermediate layer or element.
