Embodiment Construction

[0015] refer to figure 1 , the present invention proposes a blue light filter display with blue wavelength red shift, comprising: LED, light guide plate, optical film material, lower polarizer, LCD and upper polarizer.

[0016] LED, light guide plate, optical film material, lower polarizer, LCD and upper polarizer are fixed and assembled in the display frame through plastic frames as a display function module. In the display function module, LED is used as a light source to emit blue light with a dominant wavelength of 460-480nm and into the light guide plate.

[0017] In this embodiment, the dominant wavelength of the light emitted by the LED is red-shifted from about 450nm to 460-480nm by red-shifting the blue light, so that the dominant wavelength of the blue light entering the user's eyes is 460nm-480nm, thereby reducing the impact on the user's eyes of the display device. hazards.

[0018] In this embodiment, the red-shifting of the blue light emitted by the LED can be ...

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...
