Problems solved by technology

The backlight and RGB color resistance used to realize the wide color gamut technology have the problem of insufficient color purity
The stray light in the backlight and the overlapping parts of the RGB three chromatograms will significantly affect the color purity, making the primary color of the panel impure, and the display color is not realistic, which affects the display quality of the panel to a certain extent

Abstract

The invention provides a controllable switch optical film and a liquid crystal displayer. The controllable switch optical film includes a transparent substrate and multiple layers of nanowire thin films arranged on the transparent substrate; the multiple layers of nanowire thin films include multiple layers of tungsten oxide nanowire thin films and multiple layers of silver nanowire thin films which are alternately superposed; the two layers of nanowire thin films on the outermost side refer to silver nanowire thin films; the controllable switch optical film has the performance of a controllable switch, when electrified, the film has the light filtering function and can filter out stray light of one wave band in backlight, the purity of the backlight is improved, wide color gamut display of the liquid crystal displayer is achieved, when electricity is cut off, the light filtering capacity is lost, the optical film becomes a transparent thin film, and the normal display of the liquid crystal displayer is not affected. Therefore, the light filtering function of the optical film can be controlled through electrification, conversion, between normal display and wide color gamut display,of the liquid crystal displayer is achieved, and a better visual effect is thus achieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a controllable switch optical film and a liquid crystal display. Background technique [0002] In recent years, wide color gamut technology in the TFT-LCD industry is an important trend in the development of panel color display. The realization of wide color gamut mainly relies on new color rendering technologies such as backlight and RGB color resistance, OLED, QD, Q-LED, and QD-CF. But at present, the color filter (CF) composed of RGB color resistance is still mainly used for color rendering. The backlight source and RGB color resistance used to realize the wide color gamut technology all have the problem of insufficient color purity. The stray light in the backlight and the overlapping parts of the RGB three-color spectrum will significantly affect the color purity, making the primary color of the panel impure, and the displayed color is not realistic, which affects the dis...
