Detailed Description

In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.

Fig. 1 is a schematic structural diagram of a multi-layer display panel provided in the present disclosure, and as shown in fig. 1, the multi-layer display panel 10 includes a first display module 100, and the first display module 100 includes: a first display layer 110, a second display layer 120, and a third display layer 130.

The first light emitting surface of the first display layer 110 faces the second display layer 120, the second light emitting surface of the first display layer 110 faces the third display layer 130, and the first light emitting surface and the second light emitting surface are opposite to each other.

The first display layer 110 includes: the array comprises a plurality of first pixel units 111, and each first pixel unit 111 comprises a plurality of first sub-pixel units 1111. The second display layer 120 includes: the display panel includes a first light shielding unit 121 and first display particles 122, the first light shielding unit 121 faces a region between adjacent first sub-pixel units 1111, and the first display particles 122 are located in the region between the adjacent first light shielding units 121. The third display layer 130 includes: a second light shielding unit 131 and second display particles 132, the second light shielding unit 131 directly faces the region between the adjacent first sub-pixel units 1111, and the second display particles 132 are located in the region between the adjacent second light shielding units 131.

The first display layer 110, the second display layer 120, and the third display layer 130 are used to display an image.

For example, as shown in fig. 1, the first pixel units 111 are distributed in an array along the X direction and the Y direction, each first pixel unit 111 may include three first sub-pixel units 1111, which are a red sub-pixel unit, a green sub-pixel unit, and a blue sub-pixel unit, respectively, and each first pixel unit 111 may also include four first sub-pixel units 1111, which are a red sub-pixel unit, a green sub-pixel unit, a blue sub-pixel unit, and a white sub-pixel unit, respectively. In this embodiment, the type of the first sub-pixel unit is not particularly limited.

A certain gap exists between the adjacent first sub-pixel units 1111, metal wirings are disposed in the gap, and the metal wirings are used for electrically connecting the corresponding first sub-pixel units 1111 and the driving circuit, so that the driving circuit can control the first sub-pixel units 1111 to emit light. The first sub-pixel unit 1111 is located in the display area of the first display layer 110, that is, the metal trace is located in the display area, when the external ambient light irradiates the first display layer 110, the metal trace can reflect the external ambient light, and the reflected external ambient light is emitted through the light emitting surface of the first display layer 110, which results in a higher intensity of the external ambient light emitted from the first display layer 110, and a glare problem occurs when a user watches the external ambient light.

For example, the first light-shielding units 121 in the second display layer 120 may be light-shielding bars extending along the X direction and arranged along the Y direction, and/or light-shielding bars extending along the Y direction and arranged along the X direction, and may also be light-shielding blocks arranged along the X direction and the Y direction, and the embodiment does not specifically limit the specific form and color of the first light-shielding units. The regions between the first light shielding units 121 are filled with the first display particles 122, the first display particles 122 include white display particles and black display particles, the white display particles can reflect light beams and thus display white, and the black display particles can absorb light beams and thus display black. In this way, the second display layer 120 can display a black-and-white image by the white display particles and the black display particles.

The second display layer 120 faces the first light emitting surface of the first display layer 110, and the first light shielding unit 121 faces the area between the adjacent first sub-pixel units 1111, so that it is obvious that the first light shielding unit 121 can cover the metal traces in the first display layer 110. If an image is displayed through the first light emitting surface of the first display layer 110, the light beams emitted by the first sub-pixel unit 1111 exit through the area between the adjacent first light shielding units 121, as shown in fig. 1 (the solid arrows indicate the light beams emitted by the first light shielding units), that is, the first light shielding units 121 do not shield the light beams emitted by the first sub-pixel unit 1111, so as to avoid the second display layer 120 from affecting the display effect of the first display layer 110. Meanwhile, the external ambient light also irradiates the inside of the first display layer 110 through the first light emitting surface, and before the external ambient light enters the inside of the first display layer 110, the first light shielding unit 121 shields a portion of the external ambient light, as shown in fig. 1 (the dotted arrow represents the external ambient light), so as to reduce the intensity of the light entering the inside of the first display layer 110. The external ambient light incident into the first display layer 110 is partially reflected by the metal traces, and the first light-shielding unit 121 can block part of the reflected light from being emitted from the first light-emitting surface of the first display layer 110, so as to further reduce the intensity of the external ambient light emitted from the first light-emitting surface of the first display layer 110.

The third display layer 130 faces the second light emitting surface of the first display layer 110, the second light shielding unit 131 in the third display layer 130 has a structure and a function similar to those of the first light shielding unit 121, and the second display particles 132 in the third display layer 130 have a structure and a function similar to those of the first display particles 122, which will be described in detail in the description of the first light shielding unit 121 and the first display particles 122. Similarly, the second light-shielding unit 131 does not shield the light beam emitted by the first sub-pixel unit 1111, so as to avoid the third display layer 130 from affecting the display effect of the second light-emitting surface of the first display layer 110; meanwhile, the second light-shielding unit 131 shields a portion of the external ambient light, so as to reduce the intensity of the light incident into the first display layer 110, and the first light-shielding unit 121 can also block a portion of the reflected light from exiting from the second light-exiting surface of the first display layer 110, thereby further reducing the intensity of the external ambient light exiting from the second light-exiting surface of the first display layer 110.

The second display layer 120 and the third display layer 130 display images, so that double-sided display of the multi-layer display panel can be realized, and meanwhile, when the first display layer 110 displays images, the second display layer 120 and the third display layer 130 do not affect the display effect of the first display layer 110. In addition, can shelter from partial external environment light through second display layer 120 and third display layer 130, reduce the intensity of incidenting to the inside external environment light of first display layer, and then can reduce the intensity of the external environment light that first display layer jetted out, the shading unit can also shelter from the internal metal of first display layer and walk the reflected external environment light of line, further reduces the intensity of the external environment light that first display layer jetted out to can solve the glare problem.

In addition, because the shading unit is located between the adjacent first sub-pixel units, the shading unit can not shield the light beam emitted by the first sub-pixel unit, the influence on the display quality of the first display layer is avoided, the shading unit can shield part of external environment light, the intensity of the external environment light incident to the inside of the first display layer is reduced, namely, the intensity of the external environment light emitted by the first display layer can be reduced, meanwhile, the shading unit can also shield the external environment light reflected by the metal wiring in the first display layer, the intensity of the external environment light emitted by the first display layer is further reduced, and therefore the glare problem can be solved.
