Quantum dot blue light filtering film and display thereof

Abstract

A quantum dot blue light filtering film and a display thereof relate to the technical field of a flat display, and solve the problem that the brightness of a display module after filtering will be reduced in different degrees if conventional blue light filtering films absorb part of blue light components. The quantum dot blue light filtering film comprises a substrate, a quantum dot coating layer evenly coating the substrate, and a protective film covering the quantum dot coating layer. The quantum dot coating layer comprises more than one quantum dot that emits non-blue light through stimulation of part of blue light in white incident light so as to reduce brightness of blue light in white outgoing light. Compared with the solution of the prior art, the solution of the invention utilizes blue light in white light to simulate quantum dots in the quantum dot blue light filtering film to emit light of other colors instead of just simply filtering blue light, so that brightness of blue light in white light is reduced, a clean blue light eye protection purpose is achieved, the intensity of light of other colors is increased, and the overall brightness of white light will not be lost or will be lost quite slightly.

Description

Technical field [0001] The invention relates to the technical field of flat panel displays. Background technique [0002] The existing various types of displays emit short-wave blue light that is harmful to the eyes. When light enters the human eye, the human eye lens absorbs a small part of the blue light, and the remaining blue light is absorbed by the macula; the lens absorbs excessive blue light , Can cause cataracts, and blue light can cause macular lesions. Short-wave blue light, especially blue-violet light between 415-450nm, has extremely high energy and can penetrate the lens directly to the retina. The highest damage to retinal cells. Therefore, it is necessary to use pure blue eye protection products to make up for the defects of current display screens. At present, there are three main directions for the net blue eye protection products: [0003] A. The blue light filter film (including tempered film, etc.) attached to the surface of the LCM. The film material of th...

Problems solved by technology

[0006] To sum up, the purpose of the present invention is to solve 1. Existing types of blue light filter films (points A and B) absorb part of the blue light component and reduce its energy, resulting in different brightness of the display module after filtering. 2. Using backlight LED lights to move the main wavelength of blue light to a longer direction, the excitation efficiency of phosphor powder is reduced, resulting in loss of brightness, which affects the overall brightness of the module. A quantum dot blue light filter is proposed Membranes and their displays
