[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0028] The embodiment of the present application provides a display module and a display panel, and the display module can achieve good display.

[0029] See also Figure 1 , Figure 1 A first structural schematic diagram of a display module provided in an embodiment of the present application.

[0030] The embodiment of the present application provides a display module 100, which includes a first substrate 101, a second substrate 102, a light-emitting unit 103, a driving module 104, and a wiring terminal 105. The first substrate 101 and the second substrate 102 are stacked, the light-emitting unit 103 is arranged on the first substrate 101 away from the second substrate 102, the driving module 104 is arranged between the first substrate 101 and the second substrate 102, the driving module 104 is electrically connected to the light-emitting unit 103, and the wiring terminal 105 is arranged on a side of the second substrate 102 away from the first substrate 101, and the wiring terminal 105 is electrically connected to the driving module 104.

[0031] The base of the first substrate 101 and the second substrate 102 can be a transparent insulator, and the specific material can be phenolic resin, etc. In order to further present the display effect and maintain the good display when the display screen is partially or completely black, the display module 100 also includes a black colorant, which is dispersed in the first substrate 101 so that the first substrate 101 is black as a whole. Among them, the black colorant can be carbon powder or carbon nanotubes. It is worth noting that although carbon powder or carbon nanotubes can be conductive, the carbon powder or carbon nanotubes in this application are dispersed in a transparent insulator, and the concentration is relatively small. The fine carbon powder or carbon nanotubes do not contact each other, so the first substrate 101 as a whole is still an insulator. The second substrate 102 can be transparent, or it can be black or other colors by adding black or other colorants.

[0032] The first substrate 101 and the second substrate 102 may have a high refractive index, and at the same wavelength, the refractive index may be 1.76 to 1.78, which is close to that of sapphire. Because the first substrate 101 and the second substrate 102 are made of resin material, they have the advantages of low manufacturing cost, strong operability and modifiability, and their properties can be further changed through physical and chemical reactions.

[0033] The light-emitting unit 103 may be a Micro LED (Micro Light Emitting Diode Display) or a mini LED (Mini Light Emitting Diode Display). In the embodiment of the present application, Micro LED is taken as an example, specifically an active drive (Active Matrix, AM) type Micro LED. Compared with the traditional passive drive (passive matrix, PM) type Micro LED, active drive can independently control each sub-pixel, the screen is flicker-free, the driving current is lower, and the device life is longer.

[0034] See also Figure 2 as well as Figure 3 , Figure 2 A schematic diagram of the first structure of the light-emitting unit provided in the embodiment of the present application, Figure 3 A second structural schematic diagram of a light-emitting unit provided in an embodiment of the present application. The light-emitting unit 103 can be used as a pixel unit, and the light-emitting unit 103 can include multiple sub-light-emitting units 103, such as three micro LEDs, corresponding to sub-pixels of different colors. For example, the light-emitting unit 103 includes a red sub-light-emitting unit 1031, a green sub-light-emitting unit 1032, and a blue sub-light-emitting unit 1033. The multiple sub-light-emitting units 103 can be arranged in an array on the first substrate 101.

The first substrate 101 and the second substrate 102 are stacked, the light-emitting unit 103 is arranged on a side of the first substrate 101 away from the second substrate 102, and the driving module 104 is arranged between the first substrate 101 and the second substrate 102. That is, the light-emitting unit 103 and the driving module 104 are respectively arranged on both sides of the first substrate 101, the wiring terminal 105 is arranged on a side of the second substrate 102 away from the first substrate 101, and is electrically connected to the driving module 104. The external circuit transmits a signal from the wiring terminal 105 to the driving module 104, and the driving module 104 is used to drive the light-emitting unit 103 to emit light. The light-emitting unit 103 and the driving module 104 are not on the same plane, so that the driving module 104 can avoid blocking the light emitted by the light-emitting unit 103; the wiring terminal 105 is not on the same plane as the light-emitting unit 103 and the driving module 104, so that the wiring between the external circuit and the light-emitting unit 103 and the driving module 104 is avoided and the process steps are reduced. Therefore, the display module 100 in this application sequentially packages the light-emitting unit 103, the driving module 104 and the wiring terminal 105 along the height direction of the display module 100 through the first substrate 101 and the second substrate 102, which can improve the light-emitting performance and have a lower process cost.
