[0001] This application relates to the field of display technology, and in particular to a display panel and display device. Background Technology

[0002] Display panels that use organic light-emitting diodes (OLEDs) to achieve display functions are called OLED display panels. Due to their high color gamut, thinness, and flexibility, they have become the mainstream display structure.

[0003] However, current OLED display panels have relatively low luminous efficiency. In order to increase brightness, the current can only be increased, resulting in high power consumption and short lifespan of display devices. Summary of the Invention

[0068] 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.

[0069] Please refer to Figures 1, 2, and 3. Figure 1 is a top view of a display panel 000 provided in an embodiment of this application. Figure 2 is an enlarged schematic diagram of point P in Figure 1. Figure 3 is a cross-sectional schematic diagram of the display panel provided in an embodiment of this application at point AA' in Figure 2. The display panel 000 may include: a driving backplate 100, a pixel definition layer 200, a light-emitting layer 301, a first functional layer 400, a second functional layer 500, an auxiliary support layer 600, and a reflective part 700.

[0070] The pixel definition layer 200 in the display panel 000 is located on one side of the driving back panel 100, and the pixel definition layer 200 may have multiple pixel openings K. The pixel definition layer 200 may have light-absorbing properties. For example, the pixel definition layer 200 may be made of a black light-absorbing material, so that the pixel definition layer 200 can absorb ambient light incident on the display panel 000, thereby reducing the reflectivity of the display panel 000 to ambient light.

[0071] The light-emitting layer 301 in the display panel 000 is located on the side of the pixel definition layer 200 away from the driving backplate 100, and at least a portion of the light-emitting layer 301 is located within a plurality of pixel openings K.

[0072] Here, the pixel definition layer 200 and the light-emitting layer 301 in the display panel 000 can be used to form multiple light-emitting devices 300. For example, the display panel 000 may also include a first electrode layer 302 and a second electrode layer 303. The first electrode layer 302 may be located on the side of the pixel definition layer 200 facing the driving backplate 100. The first electrode layer 302 may include multiple separately disposed first electrodes 302a, which may correspond to multiple pixel openings K. The orthographic projection of the pixel opening K onto the driving backplate 100 may lie within the orthographic projection of the corresponding first electrode 302a onto the driving backplate 100. In this case, the portion of the light-emitting layer 301 located within the pixel opening K may contact the first electrode 302a. The second electrode layer 303 may be located on the side of the light-emitting layer 301 away from the driving backplate 100, and at least a portion of the second electrode layer 303 may also be located within the multiple pixel openings K. Thus, for any pixel opening K, the first electrode 302a corresponding to this pixel opening K, and the portions of the light-emitting layer 301 and the second electrode layer 303 distributed within this pixel opening K can constitute a light-emitting device 300.

[0073] Multiple light-emitting devices 300 can be electrically connected to the driving backplate 100, which is used to drive the light-emitting devices 300 to emit light, thereby realizing the display function of the display panel 000.

[0074] At least a portion of the second functional layer 500 in the display panel 000 is located within a plurality of first openings 400a and contacts the inner wall of each first opening 400a. Exemplarily, the angle between the inner wall of the first opening 400a and the side of the first functional layer 400 facing the drive backplate 100 can be an acute angle; for example, the angle between the inner wall of the first opening 400a and the side of the first functional layer 400 facing the drive backplate 100 can be 45 degrees to 85 degrees. Thus, the angle between the portion of the second functional layer 500 located within the first openings 400a and the contact surface of each first opening 400a and the side of the first functional layer 400 facing the drive backplate 100 can also be an acute angle.

[0075] The refractive index of the second functional layer 500 is greater than that of the first functional layer 400. For example, the refractive index of the first functional layer 400 may be 1.45 to 1.5, and the refractive index of the second functional layer 500 may be 1.65 to 1.75.

[0076] In this situation, since the orthographic projection of the pixel aperture K on the driving backplate 100 lies within the orthographic projection of the corresponding first aperture 400a on the driving backplate 100, and at least a portion of the second functional layer 500 lies within the plurality of first apertures 400a, light emitted by the light-emitting device 300 can enter the second functional layer 500. Because the portion of the second functional layer 500 located within the first apertures 400a is in contact with the inner wall of each first aperture 400a, and the refractive index of the second functional layer 500 is greater than that of the first functional layer 400, light rays incident on the contact surface between the portion of the second functional layer 500 located within the first apertures 400a and the first functional layer 400 are highly susceptible to total internal reflection. That is, light rays incident on the inner wall of the first opening 400a are very likely to undergo total emission, thereby changing the light transmission path. This allows the reflected light rays to exit from the side of the second functional layer 500 away from the driving backplate 100, and the angle between the reflected light rays and the normal of the driving backplate 100 is small, which can improve the light emission efficiency of the display panel 000 at small viewing angles.

[0077] The auxiliary support layer 600 in the display panel 000 can be located on the side of the light-emitting layer 301 away from the driving back plate 100. The auxiliary support layer 600 can have a plurality of second openings 600a. The plurality of second openings 600a can correspond to a plurality of pixel openings K. The orthographic projection of the pixel opening K on the driving back plate 100 is located within the orthographic projection of the corresponding second opening 600a on the driving back plate 100.

[0078] The reflective portions 700 in the display panel 000 are at least distributed on the inner walls of each of the second openings 600a. For example, the angle between the inner wall of the second opening 600a and the side of the auxiliary support layer 600 facing the drive back plate 100 can be an acute angle; for instance, the angle between the inner wall of the second opening 600a and the side of the auxiliary support layer 600 facing the drive back plate 100 can be between 45 degrees and 85 degrees. Thus, the angle between the portion of the reflective portions 700 distributed on the inner walls of each of the second openings 600a and the side of the auxiliary support layer 600 facing the drive back plate 100 can also be an acute angle.

[0079] In this case, since the orthographic projection of the pixel opening K on the driving back plate 100 is located within the orthographic projection of the corresponding second opening 600a on the driving back plate 100, and the reflective part 700 is distributed at least on the inner wall of each second opening 600a, some of the light emitted by the light-emitting device 300 with a large viewing angle can be directed to the reflective part 700 and reflected on the surface of the reflective part 700, thereby changing the light transmission path. This allows the reflected light to exit from the second opening 600a, and the angle between the reflected light and the normal of the driving back plate 100 when it exits is small, thereby further improving the light emission efficiency of the display panel 000 in the direction of a small viewing angle.

[0080] Therefore, the display panel can not only achieve total internal reflection of some of the wide-viewing-angle light emitted by the light-emitting device 300 through the cooperation between the second functional layer 500 with a higher refractive index and the first functional layer 400 with a lower refractive index, but also reflect some of the wide-viewing-angle light emitted by the light-emitting device 300 through the reflective part 700 located on the inner wall of the second opening 600a of the auxiliary support layer 600. In this way, the brightness of the display panel 000 at the positive viewing angle can be further improved without increasing the driving current, thereby reducing power consumption and extending the lifespan of the display panel 000.

[0081] In summary, the display panel provided in this application may include: a driving backplane, a pixel definition layer, a light-emitting layer, a first functional layer, a second functional layer, an auxiliary support layer, and a reflective portion. The display panel can not only achieve total internal reflection of a portion of the light emitted from the light-emitting device across a wide viewing angle through the cooperation between the second functional layer with a higher refractive index and the first functional layer with a lower refractive index, but also reflect a portion of the light emitted from the light-emitting device across a wide viewing angle through the reflective portion located on the inner wall of the second opening in the auxiliary support layer. This allows for further improvement in the brightness of the display panel at the forward viewing angle without increasing the driving current, thereby reducing power consumption and extending the lifespan of the display panel.

[0082] It should be noted that, in some possible implementations, the first functional layer 400 in the display panel 000 can be made of a transparent material, and the second functional layer 500 in the display panel 000 can be made of a light-filtering material. The refractive index of the second functional layer 500 is greater than that of the first functional layer 400.

[0083] For example, the second functional layer 500 may include a plurality of color filter blocks, which correspond to a plurality of first openings 400a. The color filter blocks are located at least within the corresponding first openings 400a and are in contact with the inner wall of each first opening 400a.

[0084] As shown in Figure 1, the light-emitting devices 300 in the display panel 000 may include a plurality of first-type light-emitting devices 300a and a plurality of second-type light-emitting devices 300b. The plurality of first-type light-emitting devices 300a and the plurality of second-type light-emitting devices 300b are arranged in multiple columns along a first direction X and in multiple rows along a second direction Y. Here, the first direction X may intersect with the second direction Y; for example, in one possible case, the first direction X may be perpendicular to the second direction Y. Light-emitting devices 300 in adjacent rows may be staggered, and light-emitting devices 300 in adjacent columns may also be staggered. For example, the first-type light-emitting device 300a may be a green light-emitting device 300a, and the second-type light-emitting devices 300b may include alternating red light-emitting devices 300b1 and blue light-emitting devices 300b2.

[0085] The light-emitting device 300 can also have various shapes. For an exemplary embodiment, please refer to Figure 1. The shape of the light-emitting device 300 is circular. In other possible implementations, the light-emitting device 300 can also be other shapes, such as rectangle, rhombus, etc.

[0086] Therefore, the multiple color filters in the second functional layer 500 can be color filters that correspond one-to-one with the multiple light-emitting devices 300. For example, the color filters may include a red filter corresponding to the red light-emitting device 300b1, a green filter corresponding to the green light-emitting device 300a, and a blue filter corresponding to the blue light-emitting device 300b2. Correspondingly, only red light can pass through the red filter, only green light can pass through the green filter, and only blue light can pass through the blue filter. In this way, the display purity of different colors of light in the display panel 000 can be improved, thereby improving the display quality of the display panel 000.

[0087] In other possible implementations, both the first functional layer 400 and the second functional layer 500 in the display panel 000 can be made of transparent material. The refractive index of the second functional layer is greater than that of the first functional layer.

[0088] In this application embodiment, the relative positional relationship between the first opening 400a of the first functional layer 400 and the second opening 600a of the auxiliary support layer 600 can be designed in various ways. This application embodiment will illustrate the following three design methods as examples:

[0089] The first design method is illustrated in Figure 4, which is a schematic diagram of the film layer structure of a display panel provided in an embodiment of this application. The first opening 400a of the first functional layer 400 and the second opening 600a of the auxiliary support layer 600 are nested in a direction parallel to the driving back plate 100, and the orthographic projection of the first opening 400a on the driving back plate 100 is located within the orthographic projection of the second opening 60a on the driving back plate 100.

[0090] In this configuration, the first functional layer 400 can cover the auxiliary support layer 600 and the reflective portion 700. Specifically, in the direction parallel to the drive backplate 100, the portion of the reflective portion 700 located on the inner wall of the second opening 600a is distributed between the first functional layer 400 and the auxiliary support layer 600. The thickness of the auxiliary support layer 600 in the direction perpendicular to the drive backplate 100 can be 1.5 micrometers to 2 micrometers, and the minimum thickness of the first functional layer 400 in the direction perpendicular to the drive backplate 100 can be 1.5 micrometers to 2.5 micrometers.

[0091] In this way, after the light emitted by the light-emitting device 300 passes through the second functional layer 500 and strikes the inner wall of the first opening 400a, the light rays with a larger incident angle that strike the inner wall of the first opening 400a can undergo total reflection, thereby changing the transmission path of the light. This allows the light rays after total reflection to exit from the side of the second functional layer 500 away from the driving back plate 100. Moreover, the angle between the reflected light rays and the normal of the driving back plate 100 is small when they exit. Therefore, the light emission efficiency of the display panel 000 at small viewing angles can be improved. This can improve the brightness of the display panel 000 at the front viewing angle without increasing the driving current, reduce power consumption, and extend the service life of the display panel 000.

[0092] Light rays with a small incident angle that strike the inner wall of the first opening 400a will not undergo total internal reflection. It should be noted that in this embodiment, the first functional layer 400 can be made of a transparent material. Therefore, light rays with a small incident angle that strike the inner wall of the first opening 400a can be refracted into the first functional layer 400, allowing this refracted light to strike the reflective part 700 and be reflected on its surface. This changes the light transmission path, allowing the light reflected by the reflective part 700 to exit from the second opening 600a. Furthermore, the angle between the reflected light and the normal to the driving backplate 100 is smaller, thus significantly improving the light extraction efficiency of the display panel 000 at narrow viewing angles. This allows for further improvement in the brightness of the display panel 000 at its frontal viewing angle without increasing the driving current, thereby reducing power consumption and extending the lifespan of the display panel 000.

[0093] It should be noted that, please refer to Figure 5, which is a schematic diagram of another film layer structure of a display panel provided in an embodiment of this application. In the direction parallel to the driving backplate 100, the distance d1 between the edge of the first opening 400a and the edge of the pixel opening K can be 0 micrometers to 2 micrometers. In this way, it can be ensured that the wide-viewing-angle light emitted by the light-emitting device 300 can be directed as much as possible to the contact surface between the portion of the second functional layer 500 located within the first opening 400a and the first functional layer 400 and undergo total internal reflection, avoiding the wide-viewing-angle light from entering the first functional layer 400 on the side of the first functional layer 400 facing the driving backplate 100, causing light loss, thereby improving the light utilization rate of the display panel 000 and reducing power consumption.

[0094] In the direction parallel to the driving backplate 100, the distance d2 between the edge of the second opening 600a and the edge of the pixel opening K can be 2 micrometers to 4 micrometers. This ensures that as much of the wide-viewing-angle light emitted by the light-emitting device 300 as possible is directed towards and reflected from the portion of the reflective part 700 distributed on the inner wall of the second opening 600a, preventing light from being blocked by the reflective part 700 and thus avoiding light loss due to light not escaping from the display side of the display panel 000. This improves the light utilization rate of the display panel 000 and reduces power consumption.

[0095] Furthermore, when the first opening 400a and the second opening 600a are nested in a direction parallel to the drive backplate 100, the distance d1 between the edge of the first opening 400a and the edge of the pixel opening K is less than the distance d2 between the edge of the second opening 600a and the edge of the pixel opening K.

[0096] It should be noted that the display panel 000 may further include a light-absorbing layer 1200. For example, the light-absorbing layer 1200 may be made of a light-absorbing material; for instance, it may be a black matrix layer. The light-absorbing layer 1200 in the display panel 000 may have multiple fifth openings 1200a, and each of the multiple fifth openings 1200a corresponds one-to-one with a multiple light-emitting device in the display panel 000. The orthographic projection of the pixel opening K in the display panel 000 onto the driving backplate 100 lies within the orthographic projection of the corresponding fifth opening 1200a onto the driving backplate 100. This ensures that the light-absorbing layer 1200 does not block the main light emitted by the light-emitting device 300, thereby improving the light extraction efficiency of the light-emitting device 300.

[0097] It should also be noted that the orthographic projection of the light-absorbing layer 1200 on the driving backplate 100 lies within the orthographic projection of the first functional layer 400 on the driving backplate 100. This ensures that the light rays at small viewing angles after total internal reflection through the sidewall of the first opening 400a and after reflection by the reflective part 700 are not absorbed by the light-absorbing layer 1200. This guarantees that both the light rays at small viewing angles after total internal reflection through the sidewall of the first opening 400a and after reflection by the reflective part 700 are emitted from the fifth opening 1200a as much as possible, thus ensuring high light emission efficiency of the display panel 000 at small viewing angles.

[0098] Here, by setting the light-absorbing layer 1200, the undesirable phenomenon of color bleeding on the display panel 000 can be effectively avoided. Furthermore, the light-absorbing layer 1200 can also absorb ambient light, reducing the reflectivity of the display panel 000 to ambient light and improving the display effect of the display panel 000. In addition, the thicker the light-absorbing layer 1200, the better its effect in preventing color bleeding and reducing ambient light reflectivity. For example, the thickness of the light-absorbing layer 1200 can range from 1 micrometer to 2 micrometers.

[0099] In this embodiment, the distribution of the light-absorbing layer 1200 can be implemented in several ways. When the first opening 400a and the second opening 600a in the display panel 000 are nested in a direction parallel to the driving backplate 100, the distribution of the light-absorbing layer 1200 is illustrated in the following two possible ways:

[0100] In a first possible implementation, as shown in Figure 4, at least a portion of the second functional layer 500 in the display panel 000 is located within a plurality of first openings 400a. The second functional layer 500 further includes a portion distributed outside the first openings 400a. The light-absorbing layer 1200 in the display panel 000 may be located between the portions of the first functional layer 400 and the second functional layer 500 distributed outside the first openings 400a. In a direction parallel to the driving backplate 100, the overlap distance between the portion of the second functional layer 500 distributed outside the first openings 400a and the light-absorbing layer 1200 may be 0 to 6 micrometers. The orthographic projection of the light-absorbing layer 1200 on the driving backplate 100 lies within the orthographic projection of the first functional layer 400 on the driving backplate 100, and the orthographic projection of the reflective portion 700 on the driving backplate 100 overlaps with the orthographic projection of the fifth opening 1200a in the light-absorbing layer 1200 on the driving backplate 100. In this case, the distance between the light-absorbing layer 1200 and the light-emitting device 300 is small, which can ensure that the probability of the light emitted by the light-emitting device 300 with a wide viewing angle being directly absorbed by the light-absorbing layer 1200 is small. This can effectively increase the emissivity of the light emitted by the light-emitting device 300 with a wide viewing angle, which is beneficial to increasing the display viewing angle of the display panel 000.

[0101] In a second possible implementation, as shown in Figure 5, the light-absorbing layer 1200 in the display panel 000 can be located on the side of the second functional layer 500 that is distributed outside the first opening 400a and faces away from the driving backplate 100. In this case, two adjacent color filters in the second functional layer 500 can contact each other. For example, a portion of the green color filter distributed outside the first opening 400a can contact the portion of the adjacent blue color filter distributed outside the first opening 400a; another portion of the green color filter distributed outside the first opening 400a can contact the portion of the adjacent red color filter distributed outside the first opening 400a. This allows for the formation of a relatively flat surface on the side of the second functional layer 500 facing away from the driving backplate 100, ensuring a better effect in forming the light-absorbing layer 1200. In other possible implementations, as shown in Figure 4, two adjacent color filters in the second functional layer 500 may not contact each other.

[0102] The orthographic projection of the light-absorbing layer 1200 on the driving backplate 100 lies within the orthographic projection of the first functional layer 400 on the driving backplate 100, and the orthographic projection of the reflective portion 700 on the driving backplate 100 overlaps with the orthographic projection of the fifth opening 1200a in the light-absorbing layer 1200 on the driving backplate 100. In this case, the light-absorbing layer 1200 can also absorb some of the ambient light incident on the display panel 000, which helps to reduce the reflectivity of the display panel 000 to ambient light and improve the display effect of the display panel 000.

[0103] The second design is illustrated in Figure 6, which is a schematic diagram of the film structure of another display panel provided in an embodiment of this application. The first opening 400a of the first functional layer 400 and the second opening 600a of the auxiliary support layer 600 are arranged in a direction perpendicular to the driving back plate 100, and the first opening 400a is closer to the driving back plate 100 than the second opening 600a.

[0104] In this configuration, the orthographic projection of the first opening 400a onto the driving backplate 100 lies within the orthographic projection of the second opening 600a onto the driving backplate 100, and the orthographic projections of the first opening 400a and the second opening 600a onto the driving backplate 100 do not coincide. For example, in a direction parallel to the driving backplate 100, the distance d1 between the edge of the first opening 400a and the edge of the pixel opening K can be 0 micrometers to 2 micrometers, and the distance d2 between the edge of the second opening 600a and the edge of the pixel opening K can be 1 micrometer to 4 micrometers. Furthermore, the distance d1 between the edge of the first opening 400a and the edge of the pixel opening K is less than the distance d2 between the edge of the second opening 600a and the edge of the pixel opening K.

[0105] The auxiliary support layer 600 is located on the side of the first functional layer 400 facing away from the driving backplate 100, and the orthographic projection of the auxiliary support layer 600 on the driving backplate 100 lies within the orthographic projection of the first functional layer 400 on the driving backplate 100. For example, the thickness of the first functional layer 400 in the direction perpendicular to the driving backplate 100 can be 1.5 micrometers to 2 micrometers, and the thickness of the auxiliary support layer 600 in the direction perpendicular to the driving backplate 100 can be 1 micrometer to 2 micrometers. Specifically, in the direction parallel to the driving backplate 100, the distance d1 between the edge of the first opening 400a and the edge of the pixel opening K is less than the distance d3 between the edge of the area enclosed by the portion of the reflective part 700 located on the inner wall of the second opening 600a and the edge of the pixel opening K. That is, the orthographic projection of the portion of the reflective part 700 located on the inner wall of the second opening 600a on the driving backplate 100 lies within the orthographic projection of the first functional layer 400 on the driving backplate 100. This avoids the light that undergoes total internal reflection on the inner wall of the first opening 400a being blocked by the reflective part 700, ensuring that the light can be emitted from the side of the second functional layer 500 located inside the first opening 400a away from the driving back plate 100, thereby improving the light emission efficiency of the display panel 000 at small viewing angles and reducing power consumption.

[0106] In this design approach, the distribution of the light-absorbing layer 1200 is illustrated in the following two possible implementation methods:

[0107] In one possible scenario, please refer to Figure 7, which is a schematic diagram of the film structure of another display panel provided in an embodiment of this application. The light-absorbing layer 1200 may be located on the side of the second functional layer 500 outside the first opening 400a that faces away from the driving back plate 100, and also on the side of the auxiliary support layer 600 and the reflective portion 700 that faces away from the driving back plate 100. The orthographic projection of the light-absorbing layer 1200 on the driving back plate 100 lies within the orthographic projection of the first functional layer 400 on the driving back plate 100, and the orthographic projection of the reflective portion 700 on the driving back plate 100 overlaps with the orthographic projection of the fifth opening 1200a in the light-absorbing layer 1200 on the driving back plate 100.

[0108] In another possible scenario, please refer to Figure 8, which is a schematic diagram of the film layer structure of another display panel provided in an embodiment of this application. The display panel 000 may further include: a fourth planarization layer 1300, a portion of which is located within each of the second openings 600a, and another portion of which is located on the side of the auxiliary support layer 600 facing away from the driving backplate 100. The light-absorbing layer 1200 may be located on the side of the fourth planarization layer 1300 facing away from the driving backplate 100. Since the fourth planarization layer 1300 may be made of a highly fluid organic transparent material, a relatively flat surface can be formed on the side of the fourth planarization layer 1300 facing away from the driving backplate 100, thereby ensuring a better effect in forming the light-absorbing layer 1200 on the side of the fourth planarization layer 1300 facing away from the driving backplate 100.

[0109] The third design is illustrated in Figure 9, which is a schematic diagram of another display panel film structure provided in an embodiment of this application. The first opening 400a of the first functional layer 400 and the second opening 600a of the auxiliary support layer 600 are arranged in a direction perpendicular to the driving back plate 100, and the second opening 600a is closer to the driving back plate 100 than the first opening 400a.

[0110] In this configuration, the orthographic projection of the second opening 600a onto the driving backplate 100 lies within the orthographic projection of the first opening 400a onto the driving backplate 100. For example, in a direction parallel to the driving backplate 100, the distance d1 between the edge of the first opening 400a and the edge of the pixel opening K can be 1 micrometer to 4 micrometers, and the distance d2 between the edge of the second opening 600a and the edge of the pixel opening K can be 0 micrometers to 2 micrometers. Furthermore, the distance d1 between the edge of the first opening 400a and the edge of the pixel opening K is greater than or equal to the distance d2 between the edge of the second opening 600a and the edge of the pixel opening K.

[0111] The first functional layer 400 is located on the side of the auxiliary support layer 600 opposite to the driving backplate 100, and the orthographic projection of the first functional layer 400 on the driving backplate 100 lies within the orthographic projection of the auxiliary support layer 600 on the driving backplate 100. The thickness of the auxiliary support layer 600 in the direction perpendicular to the driving backplate 100 can be 1.5 micrometers to 2 micrometers, and the thickness of the first functional layer 400 in the direction perpendicular to the driving backplate 100 can also be 1.5 micrometers to 2 micrometers. In the direction parallel to the driving backplate 100, the distance d3 between the edge of the area enclosed by the portion of the reflective part 700 located on the inner wall of the second opening 600a and the edge of the pixel opening K is less than the distance d1 between the edge of the first opening 400a and the edge of the pixel opening K. That is, the orthographic projection of the portion of the reflective part 700 located on the inner wall of the second opening 600a on the driving backplate 100 lies within the orthographic projection of the first opening 400a on the driving backplate 100. In this way, the light reflected by the reflective part 700 can directly enter the second functional layer 500 and exit on the side of the second functional layer 500 away from the driving back plate 100, reducing light loss, improving the light emission efficiency of the display panel 000 at small viewing angles, and reducing power consumption.

[0112] As shown in Figure 9, the display panel 000 may further include: a first planarization layer 800, a portion of which is located within each of the second openings 600a, and another portion of which is located on the side of the auxiliary support layer 600 facing away from the driving backplate 100. The minimum thickness of the first planarization layer 800 in the direction perpendicular to the driving backplate 100 may be 1.5 micrometers to 2 micrometers. The first functional layer 400 and the second functional layer 500 are both located on the side of the first planarization layer 800 facing away from the driving backplate 100.

[0113] Thus, when the second functional layer 500 in the display panel 000 is made of a light-filtering material, since the first planarization layer 800 can be made of a highly fluid organic transparent material, a relatively flat surface can be formed on the side of the first planarization layer 800 facing away from the driving backplate 100. This ensures a better formation of the first inorganic functional layer and the second functional layer 500 on the side of the first planarization layer 800 facing away from the driving backplate 100, thereby ensuring a better light-filtering effect for the multiple color filter blocks in the second functional layer 500 and further improving the display quality of the display panel 000. For example, the thickness of the first planarization layer 800 in the direction perpendicular to the driving backplate 100 can be 1 micrometer to 2 micrometers.

[0114] In this design approach, the distribution of the light-absorbing layer 1200 is illustrated in the following four possible implementation methods:

[0115] In one possible scenario, please refer to Figure 10, which is a schematic diagram of the film layer structure of another display panel provided in an embodiment of this application. The light-absorbing layer 1200 may be located on the side of the first functional layer 400 facing the driving backplate 100. That is, the first functional layer 400 covers the side of the light-absorbing layer 1200 away from the driving backplate 100 and covers the side of the light-absorbing layer 1200 facing the fifth opening 1200a. The orthographic projection of the light-absorbing layer 1200 on the driving backplate 100 lies within the orthographic projection of the first functional layer 400 on the driving backplate 100.

[0116] In another possible scenario, please refer to FIG11, which is a schematic diagram of the film layer structure of another display panel provided in an embodiment of this application. The light-absorbing layer 1200 in the display panel 000 may be located on the side of the first functional layer 400 facing the driving back plate 100, and on the side of the first planarization layer 800 facing the driving back plate 100. That is, the light-absorbing layer 1200 is located on the side of the reflective portion 700 and the auxiliary support layer 600 away from the driving back plate 100. In this case, the orthographic projection of the light-absorbing layer 1200 on the driving back plate 100 is located within the orthographic projection of the first functional layer 400 on the driving back plate 100, and the orthographic projection of the reflective portion 700 on the driving back plate 100 overlaps with the orthographic projection of the fifth opening 1200a in the light-absorbing layer 1200 on the driving back plate 100.

[0117] In another possible scenario, please refer to Figure 12, which is a schematic diagram of the film layer structure of another display panel provided in an embodiment of this application. The light-absorbing layer 1200 in the display panel 000 may be located between the portions of the first functional layer 400 and the second functional layer 500 distributed outside the first opening 400a. The orthographic projection of the light-absorbing layer 1200 on the driving backplate 100 lies within the orthographic projection of the first functional layer 400 on the driving backplate 100.

[0118] In another possible scenario, please refer to Figure 13, which is a schematic diagram of the film structure of another display panel provided in an embodiment of this application. The light-absorbing layer 1200 in the display panel 000 may be located on the side of the second functional layer 500 outside the first opening 400a, facing away from the driving back plate 100. The orthographic projection of the light-absorbing layer 1200 on the driving back plate 100 lies within the orthographic projection of the first functional layer 400 on the driving back plate 100.

[0119] It should be noted that, as shown in Figures 10 to 13, in the above four possible cases, in the direction parallel to the driving backplate 100, the minimum distance d8 between the light-absorbing layer 1200 and the auxiliary support layer 600 is greater than or equal to 1 micrometer, so as to ensure that the light-absorbing layer 1200 will not block the light reflected by the reflective part 700, thereby improving the light extraction efficiency of the light-emitting device 300.

[0120] Please refer to Figures 14 and 15. Figure 14 is another enlarged schematic diagram of point P in Figure 1, and Figure 15 is a cross-sectional schematic diagram of the display panel provided in this embodiment of the application at point BB' in Figure 14. In this embodiment of the application, the display panel 000 may further include: a first metal touch layer 1001, a touch insulating layer 1002, and a second metal touch layer 1003 stacked together, wherein the second metal touch layer 1003 is closer to the driving backplate 100 than the first metal touch layer 1001.

[0121] The first metal touch layer 1001 may include a plurality of first touch electrodes and a plurality of second touch electrodes disposed on the same layer, and a connecting electrode for connecting two adjacent first touch electrodes; the second metal touch layer 1003 may include a bridging electrode for connecting two adjacent first touch electrodes. The bridging electrode and the connecting electrode may be arranged alternately, and they may be insulated from each other by a touch insulating layer 1002. One of the first touch electrodes and the second touch electrode may be a touch driving electrode, and the other may be a touch sensing electrode. Through the cooperation of the touch driving electrode and the touch sensing electrode, the display panel 000 can have touch functionality.

[0122] It should be noted that the first metal touch layer 1001 in the display panel 000 may have multiple grid holes U, which may correspond to multiple pixel openings K, and the orthographic projection of the pixel opening K on the driving back panel 100 is located within the orthographic projection of the corresponding grid hole U on the driving back panel 100. Optionally, the multiple grid holes U and the multiple pixel openings K may be in one-to-one correspondence, and the orthographic projection of the pixel opening K on the driving back panel 100 is located within the orthographic projection of the corresponding grid hole U on the driving back panel 100; or, one grid hole U may correspond to multiple pixel openings K, and the orthographic projections of the multiple pixel openings K on the driving back panel 100 are all located within the orthographic projection of the corresponding grid hole U on the driving back panel 100. For ease of explanation, the embodiments of this application are illustrated using the example of a one-to-one correspondence between multiple grid holes U and multiple pixel openings K.

[0123] In this way, the light emitted by the light-emitting device 300 will not be blocked by the first touch metal layer, but will be able to shine out through their respective grid holes U. This ensures that the display panel 000 can perform the touch function without affecting the normal display of the display panel 000.

[0124] One of the plurality of touch driving electrodes and the plurality of touch sensing electrodes in the first touch metal layer can be connected by a connecting electrode in the first touch metal layer, and the other of the plurality of touch driving electrodes and the plurality of touch sensing electrodes in the first touch metal layer can be connected by a bridging electrode in the second touch metal layer. For ease of explanation, this application illustrates the case where the plurality of touch driving electrodes are connected by connecting electrodes and the plurality of touch sensing electrodes are connected by bridging electrodes. In this case, the touch insulating layer 1002 may have a plurality of first through holes 1002a, which may correspond to a plurality of bridging electrodes. The orthographic projection of the first through hole 1002a on the driving back plate 100 lies within the orthographic projection of the corresponding bridging electrode on the driving back plate 100. The touch sensing electrode overlaps with the bridging electrode through the first through hole 1002a. Therefore, the orthographic projection of the bridging electrode on the driving backplate 100 can coincide with the orthographic projection of the touch sensing electrode on the driving backplate 100. That is, the orthographic projection of the second touch metal layer on the driving backplate 100 can be located within the orthographic projection of the first touch metal layer on the driving backplate 100. The orthographic projection of the second touch metal layer on the driving backplate 100 does not coincide with the orthographic projection of the mesh hole U on the driving backplate 100. In this way, it can be ensured that the light emitted by the light-emitting device 300 will not be blocked by the second touch metal layer, thereby ensuring that the display panel 000 can realize the touch function without affecting the normal display of the display panel 000.

[0125] In this embodiment, the reflective portion 700 in the display panel 000 may be disposed on the same layer as the first metal touch layer 1001 and made of the same material, and / or, the reflective portion 700 in the display panel 000 may be disposed on the same layer as the second metal touch layer 1003 and made of the same material. The reflective portion 700 is insulated from the first metal touch layer 1001 and from the second metal touch layer 1003. This embodiment is illustrated with the following three possible implementations.

[0126] In a first possible implementation, as shown in Figure 15, the reflective portion 700 in the display panel 000 is disposed on the same layer as the first metal touch layer 1001 and is made of the same material. In this case, the touch insulating layer 1002 and the auxiliary support layer 600 can be the same film layer, and the reflective portion 700 includes a plurality of first metal rings 701 corresponding to a plurality of second openings 600a. A portion of the first metal rings 701 can be located on the inner wall of the corresponding second opening 600a, and another portion of the first metal rings 701 can be located on the side of the touch insulating layer 1002 facing away from the driving backplate 100. A plurality of mesh holes U can correspond to a plurality of first metal rings 701, and the orthographic projection of the first metal rings 701 on the driving backplate 100 lies within the orthographic projection of the corresponding mesh holes U on the driving backplate 100. Furthermore, the metal ring lines in the first metal touch layer 1001 used to form the mesh holes U are arranged at intervals from the corresponding first metal rings 701. For example, as shown in Figure 14, in a direction parallel to the drive backplate 100, the shortest distance d6 between the outer boundary of the first metal ring 701 and the edge of the adjacent mesh hole U is greater than or equal to 3 micrometers. This allows the reflective part 700 to be insulated from the first metal touch layer 1001, ensuring that the first metal ring 701 is only used to reflect light and preventing the first metal ring 701 from interfering with the touch signals in the display panel 000.

[0127] For a second possible implementation, please refer to Figures 16 and 17. Figure 16 is another enlarged schematic diagram of point P in Figure 1, and Figure 17 is a cross-sectional schematic diagram of the display panel provided in this embodiment of the application at point CC' in Figure 16. The reflective part 700 in the display panel 000 is only disposed on the same layer as the second metal touch layer 1003 and is made of the same material. In this case, the touch insulating layer 1002 is located on the side of the auxiliary support layer 600 away from the driving back plate 100, and the reflective part 700 includes: a plurality of second metal rings 702 corresponding to a plurality of second openings 600a. Among them, a portion of the second metal rings 702 is located on the inner wall of the corresponding second opening 600a, and another portion of the second metal rings 702 is located on the side of the auxiliary support layer 600 away from the driving back plate 100.

[0128] When the reflective portion 700 in the display panel 000 is disposed in the same layer as the second metal touch layer 1003 and is made of the same material, multiple mesh holes U can correspond to multiple second metal rings 702. The orthographic projection of the second metal ring 702 on the driving back plate 100 is located within the orthographic projection of the corresponding mesh hole U on the driving back plate 100. Furthermore, the orthographic projection of the metal ring lines in the first metal touch layer 1001 used to form the mesh holes U on the driving back plate 100 is spaced apart from the orthographic projection of the corresponding second metal ring 702 on the driving back plate 100. For example, as shown in FIG16, in the direction parallel to the driving back plate 100, the shortest distance d7 between the outer boundary of the second metal ring 702 and the edge of the adjacent mesh hole U is greater than or equal to 3 micrometers. This ensures that the reflective portion 700 is insulated from the second metal touch layer 1003, ensuring that the second metal ring 702 is only used to reflect light, and preventing the second metal ring 702 from interfering with the touch signals in the display panel 000.

[0129] It should be noted that when the second opening 600a is closer to the driving backplate 100 than the first opening 400a, and the display panel 000 includes the first planarization layer 800, as shown in Figure 17, the first planarization layer 800 and the touch insulating layer 1002 can be the same film layer. A portion of the touch insulating layer 1002 is located within each of the second openings 600a, and another portion of the touch insulating layer 1002 is located on the side of the auxiliary support layer 600 facing away from the driving backplate 100. This ensures better flatness on the side of the touch insulating layer 1002 facing away from the driving backplate 100, thereby ensuring a better effect in forming the first metal touch layer 1001 on the side of the touch insulating layer 1002 facing away from the driving backplate 100.

[0130] The display panel 000 may further include a second planarization layer 1100 located on the side of the touch insulating layer 1002 facing away from the driving backplate 100. As shown in FIG17, the first metal touch layer 1001 is located on the side of the touch insulating layer 1002 facing away from the driving backplate 100, and the second planarization layer 1100 is located on the side of the first metal touch layer 1001 facing away from the driving backplate 100. The first functional layer 400 and the second functional layer 500 in the display panel 000 are both located on the side of the second planarization layer 1100 facing away from the driving backplate 100.

[0131] Since the second planarization layer 1100 can be made of a highly fluid organic transparent material, a relatively flat surface can be formed on the side of the second planarization layer 1100 away from the driving backplate 100. This ensures that the first inorganic functional layer and the second functional layer 500 are formed on the side of the second planarization layer 1100 away from the driving backplate 100, thereby ensuring that the multiple color filter blocks in the second functional layer 500 have a good light filtering effect and further improving the display quality of the display panel 000.

[0132] A third possible implementation is illustrated in Figures 18 and 19. Figure 18 is an enlarged view of point P in Figure 1, and Figure 19 is a cross-sectional view of the display panel provided in this embodiment at point DD' in Figure 18. The reflective portion 700 in the display panel 000 may include a plurality of first metal rings 701 and a plurality of second metal rings 702, each corresponding to a plurality of second openings 600a. The first metal rings 701 may be co-layered with the first metal touch layer 1001 and made of the same material, while the second metal rings 702 may be co-layered with the second metal touch layer 1003 and made of the same material.

[0133] The auxiliary support layer 600 may include a support layer body 601 and a touch insulating layer 1002 stacked together. The touch insulating layer 1002 is located on the side of the support layer body 601 opposite to the driving back plate 100, and the orthographic projection of the touch insulating layer 1002 on the driving back plate 100 lies within the orthographic projection of the support layer body 601 on the driving back plate 100. The thickness of the support layer body 601 in the direction perpendicular to the driving back plate 100 can be 1.5 micrometers to 2 micrometers, and the thickness of the touch insulating layer 1002 in the direction perpendicular to the driving back plate 100 can be 1.5 micrometers to 2 micrometers.

[0134] The support layer body 601 may have multiple third openings 601a, and the touch insulating layer 1002 may have multiple fourth openings 1002b. The multiple third openings 601a correspond to the multiple fourth openings 1002b. The orthographic projection of a third opening 601a onto the driving backplate 100 lies within the orthographic projection of the corresponding fourth opening 1002b onto the driving backplate 100, and the boundary of the orthographic projection of the third opening 601a onto the driving backplate 100 does not coincide with the boundary of the orthographic projection of the corresponding fourth opening 1002b onto the driving backplate 100. The third opening 601a and the corresponding fourth opening 1002b constitute a second opening 600a. For example, please refer to FIG20, which is another cross-sectional schematic diagram of the display panel provided in the embodiment of this application at point DD' in FIG18. The distance d4 between the edge of the third opening 601a and the edge of the pixel opening K can be 0 micrometers to 2 micrometers, and the distance d5 between the edge of the fourth opening 1002b and the edge of the pixel opening K can be 1 micrometer to 3 micrometers. Furthermore, the distance d4 between the edge of the third opening 601a and the edge of the pixel opening K is smaller than the distance d5 between the edge of the fourth opening 1002b and the edge of the pixel opening K. This prevents the portion of light reflected from the inner wall of the third opening 601a in the reflective part 700 from being blocked by the portion of light reflected from the inner wall of the fourth opening 1002b in the reflective part 700. This effectively improves the light extraction efficiency of the display panel 000 at small viewing angles, further increases the brightness of the display panel 000 at the forward viewing angle without increasing the driving current, reduces power consumption, and extends the lifespan of the display panel 000.

[0135] It should be noted that when the reflective part 700 of the display panel 000 includes multiple first metal rings 701 and multiple second metal rings 702, and the second opening 600a is closer to the driving back plate 100 than the first opening 400a, the distance d1 between the edge of the first opening 400a and the edge of the pixel opening K can be 2 micrometers to 4 micrometers, and the distance d1 between the edge of the first opening 400a and the edge of the pixel opening K is greater than or equal to the distance d5 between the edge of the fourth opening 1002b and the edge of the pixel opening K.

[0136] It should also be noted that a portion of the first metal ring 701 is located on the inner wall of the corresponding second opening 600a, and another portion of the first metal ring 701 is located on the side of the touch insulating layer 1002 facing away from the driving back plate 100; a portion of the second metal ring 702 is located on the inner wall of the corresponding second opening 600a, and another portion of the second metal ring 702 is located on the side of the support layer body 601 facing away from the driving back plate 100. Multiple mesh holes U in the first metal touch layer 1001 correspond to multiple first metal rings 701 and multiple second metal rings 702. The orthographic projections of the first metal rings 701 and second metal rings 702 onto the driving back plate 100 are all located within the orthographic projections of the corresponding mesh holes U onto the driving back plate 100. Furthermore, the metal ring lines in the first metal touch layer 1001 used to form the mesh holes U are spaced apart from the corresponding first metal rings 701 and spaced apart from the corresponding second metal rings 702. For example, as shown in Figure 18, in a direction parallel to the drive backplate 100, the shortest distance d6 between the outer boundary of the first metal ring 701 and the edge of the adjacent mesh hole U is greater than or equal to 3 micrometers; the shortest distance d7 between the outer boundary of the second metal ring 702 and the edge of the adjacent mesh hole U is greater than or equal to 3 micrometers. This ensures that the first metal ring 701 is insulated from the first metal touch layer 1001, and the second metal ring 702 is insulated from the second metal touch layer 1003, guaranteeing that the first metal ring 701 and the second metal ring 702 are only used for reflecting light, thus preventing the first metal ring 701 and the second metal ring 702 from interfering with the touch signals in the display panel 000.

[0137] The portion of the first metal ring 701 located on the inner wall of the second opening 600a can be connected to the portion of the second metal ring 702 located on the side of the support layer body 601 opposite to the driving back plate 100. This ensures that the first metal ring 701 and the second metal ring 702 can cover the entire inner wall of the second opening 600a, resulting in a larger reflective area of ​​the reflective part 700. This significantly improves the light extraction efficiency of the display panel 000 at narrow viewing angles. Furthermore, without increasing the driving current, the brightness of the display panel 000 at the forward viewing angle can be further improved, thereby reducing power consumption and extending the lifespan of the display panel 000.

[0138] In this embodiment of the application, as shown in Figures 4 to 13, 15, 17, 19, and 20, the display panel 000 may further include an encapsulation layer 1500, located on the side of the light-emitting layer 301 facing away from the driving backplate 100. The encapsulation layer 1500 may include at least a first inorganic encapsulation layer 1501, an organic encapsulation layer 1502, and a second inorganic encapsulation layer 1503 stacked together, with the first inorganic encapsulation layer 1501 further away from the driving backplate 100 than the second inorganic encapsulation layer 1503. Here, the second inorganic encapsulation layer 1503 may contact the side of the second electrode layer 303 facing away from the driving backplate 100; that is, the second inorganic encapsulation layer 1503 may cover multiple light-emitting devices 300. The organic encapsulation layer 1502 ensures good flatness of the portion of the display panel 000 located within the display area, thus guaranteeing the effectiveness of other functional layers (e.g., auxiliary support layer 600) subsequently formed on the portion of the encapsulation layer 1500 within the display area. The first inorganic encapsulation layer 1501 can be used to cover the side of the organic encapsulation layer 1502 facing away from the driving backplate 100. Providing the encapsulation layer 1500 in the display panel 000 prevents water and oxygen from the external environment from corroding the light-emitting device 300 from the display side of the display panel 000, thereby improving the reliability of the display panel 000.

[0139] In the display panel 000, the auxiliary support layer 600 and the first functional layer 400 are both located on the side of the encapsulation layer 1500 away from the driving backplate 100.

[0140] It should be noted that in the implementation shown in Figure 15, the second metal touch layer 1003 may be directly disposed on the side of the encapsulation layer 1500 facing away from the driving backplate 100. However, the ability of the second metal touch layer 1003 to directly bond with the encapsulation layer 1500 is relatively poor. Therefore, the display panel 000 may further include a third planarization layer 900 located on the side of the encapsulation layer 1500 facing away from the driving backplate 100. The third planarization layer 900 may also be made of an organic transparent material. Furthermore, the second metal touch layer 1003 may be located on the side of the third planarization layer 900 facing away from the driving backplate 100.

[0141] Here, the third planarization layer 900 can contact the side of the first inorganic encapsulation layer 1501 opposite to the driving backplate 100, and the second metal touch layer 1003 can directly contact the side of the third planarization layer 900 opposite to the driving backplate 100. Therefore, by providing a third planarization layer 900 made of an organic transparent material between the second metal touch layer 1003 and the first inorganic encapsulation layer 1501, it can be ensured that the second metal touch layer 1003 is not easily separated from the display panel 000, thereby improving the adhesion of the film layers and ensuring high reliability of the display panel 000.

[0142] Optionally, as shown in Figures 4 to 13, 15, 17, 19, and 20, the display panel 000 may further include a cover layer 1400, which may also be made of an organic transparent material. The cover layer 1400 is further away from the driving backplate 100 relative to the reflective portion 700, the second functional layer 500, and the light-absorbing layer 1200. The cover layer 1400 can protect the reflective portion 700, the second functional layer 500, and the light-absorbing layer 1200, and can also improve the flatness of the display panel 000. Furthermore, when the display panel includes multiple organic film layers, the greater thickness of the organic material in the display panel 000 can improve the bending characteristics of the display panel 000, thus making it suitable for display panels 000 with different requirements.

[0143] In summary, the display panel provided in this application may include: a driving backplane, a pixel definition layer, a light-emitting layer, a first functional layer, a second functional layer, an auxiliary support layer, and a reflective portion. The display panel can not only achieve total internal reflection of a portion of the light emitted from the light-emitting device across a wide viewing angle through the cooperation between the second functional layer with a higher refractive index and the first functional layer with a lower refractive index, but also reflect a portion of the light emitted from the light-emitting device across a wide viewing angle through the reflective portion located on the inner wall of the second opening in the auxiliary support layer. This allows for further improvement in the brightness of the display panel at the forward viewing angle without increasing the driving current, thereby reducing power consumption and extending the lifespan of the display panel.

[0144] This application also provides a display device, which includes: a power supply component and a display panel 000 electrically connected to the power supply component. The display panel 000 may include any of the display panels 000 given above. The display device may be any product or component with display function, such as a mobile phone, tablet computer, television, advertising machine, display screen, digital photo frame, etc.

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.
