Optical composite film of low reflection and high transmittance

Abstract

The invention relates to the field of optics, and discloses an optical composite film of low reflection and high transmittance. The film comprises a first high-resistant diaphragm layer, a quantum dotlayer and a second high-resistant diaphragm layer, which are sequentially installed from top to bottom, wherein the first high-resistant diaphragm layer is opposite to a backlight source, and the second high-resistant diaphragm layer is opposite to an external environmental light source; a first AR coating layer is installed on the side, toward the backlight source, of the first high-resistant diaphragm layer, and a second AR coating layer is installed on the side, toward the external environmental light source, of the second high-resistant diaphragm layer. A plurality of minitype sunken points are installed on the first AR coating layer and the second AR coating layer. Compared with the prior art, by using a nano-zirconia coating with nanosized silica added to form a coating with bettercompactness in gaps among particles, after finishing spraying, monox on coating surface is corroded by hydrofluoric acid to form the minitype sunken points, and therefore the problem of higher reflectlight of a film surface is solved.

Description

technical field [0001] The invention relates to the field of optics, in particular to a low-reflection and high-transmittance optical combination film. Background technique [0002] The LCD panel itself does not emit light, but uses the light emitted by the backlight to display the picture. The LCDs used in mainstream mobile electronic devices use a group of light-emitting diodes on the back of the device as the white light source. Liquid crystals control the passage of light, and color filters add color to it. White light sources are expensive, so the display screens generally use blue light-emitting diodes, which are covered with phosphors to convert the emitted light into white light. Due to the limitation of fluorescent materials, the rendering ability of red light is weak, and the color mixing effect of the matching color filter is poor, and the final color gamut saturation is not good, which leads to the insufficient color gamut rendering ability of the LCD panel. It...
