Blue light wavelength redshift blue light filtering displayer

Abstract

The invention discloses a blue light wavelength redshift blue light filtering displayer which comprises an LED, a light guiding plate, an optical film material, a lower polarizer, an LCD and an upperpolarizer. By means of the blue light wavelength redshift blue light filtering displayer disclosed by the invention, a dominant wavelength of a blue light ingredient entering the eyes of a user is 460nm to 480nm; thus, harm of display equipment to the eyes of the user is reduced. Specifically, blue sub pixel of the blue light wavelength redshift blue light filtering displayer disclosed by the invention can send out blue light with the dominant wavelength as 460nm to 480nm, and the blue light can synthesize different colors with other pixels to enter the eyes of the user. Therefore, harmful blue light as 450nm or lower with very large harm to the human eyes is avoided, and after the user utilizes the blue light wavelength redshift blue light filtering displayer for a long time, cataract ormacular degeneration caused by 450nm blue light is avoided.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a blue light filter display with a red-shifted blue light wavelength. Background technique [0002] When light enters the human eye, the crystalline lens of the human eye absorbs a small amount of blue light, and the remaining blue light is absorbed by the macula; excessive blue light absorbed by the crystalline lens will cause cataracts, and blue light will cause macular lesions. Short-wave blue light, especially blue-violet light between 400-450nm, has extremely high energy and can penetrate the lens to reach the retina. For the highest damage to retinal cells. Therefore, it is necessary to use net blue eye protection products to make up for the defects of the current display screen. At present, there are two main solutions for the net blue eye protection module: [0003] A. The blue light filter film (including tempered film, etc.) pasted on the surface of the LCM, the fun...

Problems solved by technology

For plan B, the blue light filter film is added or replaced in the backlight film. The main wavelength of blue light harmful to the human eye is still 450nm and below. The harm to the human eye still exists, but the intensity is reduced, or consumers face the machine time Too long and there will still be hazards
