Problems solved by technology

Some existing liquid crystal display devices with eye-protection function paste anti-blue light protective film on the light-emitting side of the liquid crystal display panel to filter out blue light with a wavelength below 400nm, but the anti-blue light protective film will reduce the brightness of the liquid crystal display panel at the same time. Display brightness, which affects the backlight rate and transmittance of liquid crystal display devices

Abstract

The invention provides a making method of an eye protection type liquid crystal display device. According to the making method, an ultraviolet luminescence material and ultraviolet light absorber are added to a first flat layer (70) of an array substrate (100) and a second flat layer (240) of a color film substrate (200), the ultraviolet light absorber is made to absorb shortwave blue light and ultrasonic light which are emitted out by a backlight module and with wavelength below 400 nm, and meanwhile the absorbed shortwave blue light and ultrasonic light stimulate the ultraviolet luminescence material to emit out long-wave blue visible light which is over 400 nm in wavelength, in another word, the first flat layer (70) and the second flat layer (240) are utilized to convert the ultraviolet light which harms the human eyes and the shortwave blue light with the wavelength below 400 nm into the long-wave blue visible light not harmful to the human eyes and with the wavelength over 400 nm. By means of the making method, the human eyes are protected, the display brightness of a liquid crystal display panel is not lowered, and the backlight rate and the penetration rate of the liquid crystal display device are guaranteed.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing an eye-protecting liquid crystal display device. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, TVs, personal digital assistants due to their advantages of high image quality, power saving, thin body and wide application range. , digital cameras, notebook computers, desktop computers and other consumer electronics products have become the mainstream of display devices. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates. There are many vertical and...
