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.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an iodine-based polarizer and a display device. Background technique [0002] Currently, iodine-based polarizers are commonly used as polarizers in liquid crystal display devices, and the iodine-based polarizers are composed of polyvinyl alcohol (Poly Vinyl Alcohol, PVA) and iodine molecules. Since iodine-based polarizers are easy to obtain polarizing characteristics of high polarization degree and high transmittance, iodine-based polarizers are mainly used in liquid crystal displays at present. [0003] The composition and content of the iodine molecule in the polarizer will affect its optical properties. Among them, I5- in the iodine molecule has a high absorption efficiency for red light, and I5- has a large molecular weight and is easy to decompose or volatilize, and can be decomposed into I3-. In order to prevent the polarizer from showing "red change", it is necessary to ...
