Title:
OPTICAL DIAPHRAGM ASSEMBLY, DIRECT TYPE BACKLIGHT MODULE, LIQUID CRYSTAL DISPLAY SCREEN AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/082536
Kind Code:
A1
Abstract:
The present application discloses an optical diaphragm assembly, a direct type backlight module, a liquid crystal display screen and a terminal device, wherein the optical diaphragm assembly comprises an optical soft film and a connecting part, the edge of the optical soft film is connected with the connecting part, the hardness of the connecting part is greater than that of the optical soft film. The direct type backlight module comprises a back plate, a light-emitting structure arranged on the back plate and an optical diaphragm assembly facing the light-emitting structure, a middle frame is arranged on the periphery of the back plate, the connecting part of the optical diaphragm assembly is connected with the middle frame. The optical diaphragm assembly is arranged to be a structure that the optical soft film is connected with the connecting part, the structure can replace the optical diaphragm and the diffusion plate of the prior direct type backlight module, the structural complexity of the backlight module is effectively reduced, and the weight of the optical soft film is far smaller than the sum of the weight of the optical diaphragm and the weight of the diffusion plate, therefore the supporting structure does not need to be arranged to support the optical soft film, shadows are avoided, and the display effect is improved.
