Description

Technical Field

[0001] The utility model relates to the technical field of display, in particular to a display screen cover plate assembly, a solar display screen and a display module. Background Art

[0002] With the pursuit of diversified appearances of touch display screens by consumers, display screens with wood grain patterns have emerged. The display screen with a wood grain pattern mainly adds a wood grain film to a conventional display screen assembly. Different from ordinary display screens, the display screen with a wood grain pattern is not black when the screen is off, but presents a wood grain pattern. When in the display state, the area around the viewing area presents wood grain instead of black. At present, due to the addition of a solar charging function layer in the display screen with solar charging function, the thickness of the display screen increases. How to couple the solar charging function layer to the display screen with a wood grain pattern will further increase the thickness of the display screen, which does not meet the design and use requirements for thin and light screens. Summary of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a display screen cover plate assembly, a solar display screen and a display module, aiming to meet the thin and light requirements of the wood grain pattern display screen with solar charging function.

[0033] The wood grain film 3 includes a first transparent soft film 31, a wood grain printing layer 32, and a second transparent soft film 33 stacked in sequence;

[0034] The wood grain film 3 is attached to the entire back surface of the cover plate 1 through the first transparent soft film 31 using the optical adhesive layer 2;

[0035] The solar charging function layer 4 is used to convert light energy into electrical energy to supply power to the display screen. The solar charging function layer 4 is disposed around the edge of the second transparent soft film 33 to form a non-light-transmitting (black) area. The area enclosed by the inner edge of the solar charging function layer 4 corresponds to the position of the viewing area 6 (light-transmitting touch area) of the display screen.
