Abstract

The invention relates to the technical field of liquid crystal displayers, in particular to a narrow frame TFT liquid crystal display module which comprises a backlight module and a display module; the display module comprises a color film substrate and a thin film transistor substrate which are stacked; a light diffusion film is arranged on the backlight module and prepared from polyethylene glycol terephthalate, light diffusion mater batches, an organic light diffusion agent, an anti-oxidant, a light stabilizer, an ultraviolet light absorber and the like. Polyacrylamide microspheres with thegood compatibility are adopted as a carrier of a nanometer inorganic light diffusion agent, the problem that the nanometer inorganic light diffusion agent is likely to be aggregated, is not likely todisperse and is not compatible with PET resin is effectively solved, due to the size effect of the nanometer inorganic light diffusion agent, the light diffusion film has the advantages of being highin haze, refraction, light transmission rate, ground color degree and the like, the good optical performance is achieved, the color gamut of the display module can be improved, the excellent mechanical property is achieved, and the durability and adaptability of the display module can be improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a narrow-frame TFT 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 current mainstream TFT-LCD liquid crystal display refers to a thin film transistor liquid crystal display. Its working principle is to place liquid crystal molecules between two parallel color film substrates and thin film transistor substrates. There are many vertical and horizontal panels between the two glass substrates. The small wires control the liquid crystal molecules to change direction by electrifying or not, refracting the light from the back...
