Display backlight structure capable of reducing bright light harm

Abstract

The invention provides a display backlight structure capable of reducing blue light harm, the display backlight structure including a light guide plate, a reflector plate, a lower diffusion plate, an upper diffusion plate, a brightness enhancement plate, a filer film and positioning holes, wherein the reflector plate is positioned below the light guide plate; the lower diffusion plate, the upper diffusion plate and the brightness enhancement plate are sequentially arranged on the light guide plate; the filter film is positioned on the incident plane of the light guide plate; the filter film filters light waves with wave lengths from 380 microns to 420 microns; the positioning holes are positioned in the invisible ranges of the light guide plate, the reflector plate, the lower diffusion plate, the upper diffusion plate, the brightness enhancement plate and the filer film. The display backlight structure provided by the invention can be applied to various display devices. The display backlight structure is a display product which is low in cost and efficient and can reduce shortwave blue light, and can achieve the purpose of protecting the vision and health of users.

Description

technical field [0001] The invention relates to a backlight source of a display device, in particular to a display backlight structure for reducing the harm of blue light. Background technique [0002] At present, the general public has a relatively deep understanding of the damage of ultraviolet rays to the eyes, but the damage of high-energy short-wave blue light to the human eye is no less than the power of ultraviolet rays, but many people have blind spots in their knowledge of blue light. In fact, in visible light, blue light is a kind of extremely energetic high-energy short-wave light. Blue light can easily penetrate the lens of the glasses and reach the retina, causing a kind of photochemical damage to the whole glasses, which can quickly accelerate Oxidative processes in the macular area of ​​the eye can be extremely damaging to the eye. The damaging effect of high-energy short-wave blue light on the retina and lens of the fundus is called "blue light damage". [...

AI Technical Summary

Problems solved by technology

[0006] In the existing display devices, the device itself cannot reduce or filter the hazards of blue light, mainly through anti-blue glasses or surface film. This method causes considerable inconvenience to users, and requires maintenance, and does not have the convenience of use
