UNDER-SCREEN CAMERA ASSEMBLY, BACKLIGHT MODULE AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/015698
Kind Code:
A9
Abstract:
An under-screen camera assembly, a backlight module and a display apparatus. The under-screen camera assembly comprises: an OLED screen (10), wherein an OLED high-transmittance region (20) is arranged on the OLED screen (10); a first polarizer (310) and a second polarizer (320) which are arranged on the OLED high-transmittance region (20), wherein the second polarizer (320) is stacked on the first polarizer (310); liquid crystals arranged between the first polarizer (310) and the second polarizer (320); and a TFT drive circuit (50) arranged on the second polarizer (320), wherein the TFT drive circuit (50) is used to drive the liquid crystal (40) to deflect. The TFT drive circuit (50) is arranged in the under-screen camera assembly and is used to drive the liquid crystal (40) to deflect, such that when the TFT drive circuit (50) is powered on, the liquid crystal (40) deflects, and light may pass through the upper polarizer and the lower polarizer to achieve the effect of eliminating the diffraction of a far-field light source.
