Problems solved by technology

In the prior art, a high color gamut is generally achieved by adding a quantum dot film between the display modules, but the separate setting of the quantum dot film will increase the thickness of the module, reduce the overall light transmittance, and increase the difficulty of processing, while the quantum dot film As an inorganic substance that is incompatible with organic substances, particles are also difficult to add to other functional layers

Abstract

The invention relates to the technical field of liquid crystal display (LCD), and specifically relates to a high color gamut liquid crystal display (LCD) module, which comprises a liquid crystal module and a backlight module. A quantum dot photo-diffusion membrane is arranged on the backlight module. The quantum dot photo-diffusion membrane comprises polyester resin, quantum dot master batch, a light diffuser, an antioxidant, a light stabilizer, and a UV absorbent. Polyacrylonitrile microspheres with good compatibility are taken as the carriers of nano quantum dot particles; the problems thatthe agglomeration of nano quantum dot particles is easy to happen, and nano quantum dot particles are hard to disperse and are not compatible with matrix resin are solved; light can penetrate the polyacrylonitrile microspheres and is projected on the nano quantum dot particles; after the light penetrates the quantum dot photo-diffusion membrane, the wavelength range of light is enlarged; the LCD module has the characteristic of high color gamut; polyacrylonitrile can be used as a blending modifying material, and the mechanical properties are enhanced through the cooperation between polyester resin and polyacrylonitrile.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a high color gamut liquid crystal display module. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Most of the liquid crystal display devices currently on the market are backlight type liquid crystal display devices, which include a liquid crystal panel and a back light module. The working principle of the liquid crystal panel is to place liquid crystal molecules between two parallel glass substrates. There are many vertical and horizontal small wires between the two glass substrates. The direction of the liquid crystal molecules is controlled by electrifying or not, and the light of the backlight module is refracted. Come out to generate the picture. Since the liquid crystal panel itself does not emit light, the light source pro...
