[0038] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below with reference to the accompanying drawings.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0040] Secondly, the present application is described in detail with reference to the schematic diagram. When describing the embodiments of the present application in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present application. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0041] In order to better understand the technical solution and technical effects of the present application, specific embodiments will be described in detail below with reference to the accompanying drawings.

[0042] refer to Figure 1 FIG. 1 is a structural diagram of a display panel provided in an embodiment of the present application, referring to FIG. Figure 2 As shown, Figure 1 The display panel is a cross-sectional schematic diagram along the AA direction, wherein the display panel includes a first display panel and a second display panel stacked along a first direction, and the first display panel is located at the light emitting side of the second display panel.

[0043] The first display panel includes a plurality of first light-emitting units 11, and the second display panel includes a plurality of second light-emitting units 21. The first light-emitting units 11 and the second light-emitting units 21 do not overlap in the first direction, and the second light-emitting units 21 are located in the transparent area of ​​the first display panel, so that the light emitted by the second light-emitting units 21 can be emitted through the first display panel. The plurality of first light-emitting units 11 include red light-emitting units, green light-emitting units, and blue light-emitting units, so that the first display panel can realize full-light display, and the plurality of second light-emitting units 21 include red light-emitting units, green light-emitting units, and blue light-emitting units, so that the second display panel can realize full-light display.

[0044] The first display panel may include a first driving substrate 10 and a plurality of first light emitting units 11 on the first driving substrate 10. The first driving substrate 10 has a driving circuit, and the driving circuit is used to provide a control signal to the first light emitting unit 11. Figure 3 As shown, it is a structural schematic diagram of a first display panel provided in an embodiment of the present application, and the first driving substrate 10 may be a transparent substrate having a transparent area. The first driving substrate 10 may be a glass substrate. When only the first display panel is used for display, there are problems of low display quality, such as low display resolution or low display contrast. For example, due to the transparent display of the first display panel under strong light, the display contrast is not high when the first display panel is displayed alone, resulting in poor display quality. This is because in the existing glass-based Micro LED display technology, due to the eutectic process capability, it is impossible to achieve a small pixel pitch eutectic, so it is impossible to achieve a high pixel PPI display high-resolution design, which limits the resolution of the display panel.

[0045] The second display panel may include a second driving substrate 20 and a plurality of second light emitting units 21 on the second driving substrate 20. The second driving substrate 20 has a driving circuit, and the driving circuit is used to provide a control signal to the second light emitting unit 21. Figure 4 , which is a schematic diagram of the structure of a second display panel provided in an embodiment of the present application, wherein the second drive substrate 20 may be a transparent substrate or a non-transparent substrate. The second drive substrate 20 may be a glass substrate. The second display panel may assist the first display panel in displaying to improve the display quality, for example, by improving the overall display contrast or display resolution through the second light-emitting unit 21, broadening the application scenarios of the display panel, improving product performance, and enhancing product competitiveness, so that it can be used in fields such as public information display and vehicle-mounted display.

[0046] It is equivalent to the display panel including at least two driving substrates. The first display panel and the second display panel can be independently controlled, that is, the driving circuit in the first display panel and the driving circuit in the second display panel can be independently controlled, so that the first light-emitting unit 11 and the second light-emitting unit 21 can be independently controlled, so that the display panels work in different modes.

[0047] Specifically, the display panel may include a first operating mode and a second operating mode. In the first operating mode, the first light-emitting unit 11 emits light, and the second light-emitting unit 21 does not emit light, which is similar to the traditional operating mode. This can save power consumption. In the second operating mode, the first light-emitting unit 11 and the second light-emitting unit 21 both emit light, and the second light-emitting unit 21 assists the first light-emitting unit 11 in emitting light, thereby improving the display quality. For example, the second light-emitting unit 21 improves the display contrast or the display resolution.

[0048] In addition, the display panel may further include a third operating mode, in which the first light emitting unit 11 does not emit light, and the second light emitting unit 21 emits light, so that when the display performances of the first display panel and the second display panel are different, the first display panel or the second display panel may be controlled to operate according to actual needs. For example, the display resolutions of the first display panel and the second display panel may be different, so that the display panel may operate at the display resolution corresponding to the first display panel, or may operate at the display resolution corresponding to the second display panel.

[0049] A support column 22 may be provided between the first display panel and the second display panel. Figure 5 , which is a cross-sectional schematic diagram of another display panel provided in an embodiment of the present application, can solve the problem of cracking of the driving substrate due to pressure during lamination of the driving substrate.

[0050] The orthographic projection of the first light-emitting unit 11 on the second display panel has an overlapping area with the position of the support column 22, so that the arrangement of the support column 22 does not affect the density of the second light-emitting unit 21. The support column 22 may be an island structure, or a filling colloid filled between the first display panel and the second display panel, and the filling colloid may be an organic glue, which is arranged in the gap between the second light-emitting unit 21 to provide support for the gap between the first display panel and the second display panel.

[0051] Specifically, the density of the support columns 22 in the central area of ​​the display panel is greater than the density in the edge area of ​​the display panel. In this way, the supporting force provided by the support columns 22 in the central area is greater than the supporting force in the edge area. This is because the bonding force in the central area of ​​the display panel is usually greater and it is more likely to break due to bonding. The arrangement of the support columns 22 makes it difficult for the first display panel and the second display panel to break during the bonding process.

[0052] The second display panel may include a plurality of sub-panels sequentially attached along the first direction, each sub-panel includes a plurality of second light-emitting units, the plurality of second light-emitting units belonging to different sub-panels do not overlap in the first direction, and each light-emitting unit faces the transparent area of ​​other sub-panels on its light-emitting side, so that the light emitted by each light-emitting unit can be smoothly emitted, the sub-panel includes a driving circuit for providing a driving signal to the corresponding second light-emitting unit, the sub-panel may be called a driving substrate, which is equivalent to the display panel including at least three driving substrates, each driving substrate including a plurality of light-emitting units, so that the light-emitting unit density of the second display panel is further improved, and the display improvement effect of the second display panel on the first display panel is further enhanced. The second light-emitting units in the plurality of sub-panels do not overlap in the first direction, for example, further improving the display resolution of the second display panel, and when the resolution of a single display panel is limited, high-resolution display is achieved through a plurality of display panels.

[0053] refer to Figure 6 FIG. 1 is a schematic diagram of another display panel structure provided in an embodiment of the present application, referring to FIG. Figure 7 As shown, Figure 6 The cross-sectional view of the display panel along the AA direction in FIG. 1 further improves the resolution of the display panel or the contrast of the display panel. When the second display panel includes a plurality of sub-panels, support columns may also be provided between the plurality of sub-panels, that is, a sub-support column 222 is provided between the first sub-panel and the second sub-panel. The first sub-panel includes a first sub-driving substrate 200, and the second sub-panel includes a second sub-driving substrate 300.

[0054] In the present application examples, reference Figure 8 As shown, it is a cross-sectional view of another display panel provided by an embodiment of the present application. The display panel may also include a color film substrate 40 located on the light emitting side of the first display panel. The color film substrate 40 has a color film filter 41 and a black matrix 42. The color filter 41 includes a first group of filters directly opposite to the first light emitting unit 11 and a second group of filters directly opposite to the second light emitting unit 21, wherein the color filter includes a red filter, a green filter and a blue filter. The black matrix 42 is arranged between adjacent color filters 41, the red filter corresponds to the red light emitting unit, the green filter corresponds to the green light emitting unit, and the blue filter corresponds to the blue light emitting unit. In this way, the problem of light leakage and color deviation caused by the bonding between the driving substrates can be prevented.

[0055] A support column 12 may be further provided between the first display panel and the color filter substrate to provide support between the first display panel and the color filter substrate to prevent the two from being broken due to lamination.

[0056] In the embodiment of the present application, the first light-emitting unit 11 can be located on a side of the first display panel away from the second display panel, that is, the light-emitting side of the first display panel, and the second light-emitting unit 21 is located on a side of the second display panel facing the first display panel, that is, the light-emitting side of the second display panel, that is, the first display panel and the second display panel can be directly attached, refer to Figure 2 , Figure 5 , Figure 7 and Figure 8 As shown, the distance between the first light emitting unit 11 and the second light emitting unit 21 in the vertical light emitting direction is not limited, and it is easier to combine to improve the display quality. For the existing first display panel, a second display panel can be added to obtain a display panel with higher display quality without modifying the structure of the first display panel itself.

[0057] The density of the second light emitting units 21 in the central area of ​​the display panel can be lower than that in the edge area of ​​the display panel, which is conducive to setting more support columns to prevent the display panel from breaking. Correspondingly, the density of the first light emitting units 11 in the central area of ​​the display panel can be higher than that in the edge area of ​​the display panel to ensure the uniformity of the overall resolution of the display panel.

[0058] In a display scenario where the first light-emitting unit 11 and the second light-emitting unit 21 emit light simultaneously, that is, in the second working mode of the display panel, the second light-emitting unit 21 can emit monochromatic light or gray light to increase the display contrast of the first light-emitting unit 11 and save power consumption. In this way, when the display panel is in a strong light environment, the second display panel can provide a grayscale background to improve the transparent display effect of the display panel.

[0059] Specifically, in the second working mode of the display panel, the grayscale value of the second light-emitting unit 21 can be set according to the ambient light intensity of the display environment, for example, the ambient light intensity and the grayscale value are set in an inverse correlation. When the display panel is in the first display environment, the light emitted by the second light-emitting unit 21 has a first grayscale value, and when the display panel is in the second display environment, the light emitted by the second light-emitting unit 21 has a second grayscale value. When the ambient light intensity of the first display environment is greater than the ambient light intensity of the second display environment, the first grayscale value is less than the second grayscale value. In this way, a corresponding grayscale background or even a black background is provided in a strong light environment, thereby improving the display contrast of the display panel and the display effect.

[0060] In a display scenario where the first light-emitting unit 11 and the second light-emitting unit 21 emit light at the same time, that is, in the second operating mode of the display panel, the second light-emitting unit 21 can emit colored light and cooperate with the first light-emitting unit 11 for display, which is equivalent to splicing two display panels together. The density of the light-emitting units is improved to improve the resolution of the display panel, thereby obtaining a high-resolution and high-PPI display panel including multiple driving substrates.

[0061] In an embodiment of the present application, the driving circuit in the second display panel is arranged in the transparent area of ​​the first display panel. Since the driving circuit may be a light-proof setting, the overall light transmittance of the display panel can be reduced to reduce the impact of strong light on the display effect in a strong light environment and improve the display effect.

[0062] In the embodiment of the present application, the brightness of the first light-emitting unit 11 can be set according to the ambient light intensity, for example, it is positively correlated with the ambient light intensity. Specifically, in the second working mode of the display panel, if the display panel is in the first display environment, the first light-emitting unit 11 has a first brightness, and if the display panel is in the second display environment, the first light-emitting unit 11 has a second brightness. The ambient light intensity of the first display environment is greater than the ambient light intensity of the second display environment. The first brightness can be set to be greater than the second brightness, so that the display panel has a better display effect in a strong light environment.

[0063] In the embodiment of the present application, the brightness of the first light-emitting unit 11 and the brightness of the second light-emitting unit 21 can also be set according to the display environment. In the second working mode of the display panel, if the first display panel belongs to the third display environment, the brightness of the first light-emitting unit 11 can be set to be greater than the brightness of the second light-emitting unit 21; if the display panel is in the fourth display environment, the brightness of the second light-emitting unit 21 is greater than the brightness of the first light-emitting unit 11, so that the first light-emitting unit 11 and the second light-emitting unit 21 can adjust the brightness according to the display environment to meet the needs of more display scenarios.

[0064] The embodiment of the present application provides a display panel, including a first display panel and a second display panel stacked along a first direction, the first display panel is located at the light emitting side of the second display panel, the first display panel includes a plurality of first light emitting units, the second display panel includes a plurality of second light emitting units, the first light emitting units and the second light emitting units do not overlap in the first direction, the second light emitting units are located in the transparent area of ​​the first display panel, so that the light emitted by the second light emitting units can be emitted through the first display panel. The display panel may include a first operating mode and a second operating mode. In the first operating mode, the first light emitting unit emits light and the second light emitting unit does not emit light, so as to realize lower power consumption of the display panel. In the second operating mode, both the first light emitting unit and the second light emitting unit emit light, and the second light emitting unit assists the first light emitting unit in emitting light, so as to improve the display quality, for example, the second light emitting unit improves the display contrast or the display resolution.
