Title:
POLARIZER AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/012533
Kind Code:
A1
Abstract:
A polarizer (100, 210) and a display apparatus (200, 300, 400). The polarizer (100, 210) comprises a surface protective layer (170, 217), a stripping protective layer (110, 211) and an organic dye layer (130, 213), wherein the organic dye layer (130, 213) is configured with an organic dye for absorbing light with a wavelength of less than 430 nm. The polarizer can solve the problem that a dark state color point tends to be blue due to the excessive leakage of blue light where the existing display apparatus is in a dark state, can enhance the color performance capability of the display apparatus (200, 300, 400), and can also reduce the damage to human eyes caused by deep blue light.
