Display device based on liquid crystal microlens array

Abstract

The invention provides a display device based on a liquid crystal microlens array, comprising an FOG module, a liquid crystal microlens layer and a glass cover plate, the liquid crystal microlens layer is located between the FOG module and the glass cover plate, the liquid crystal microlens layer comprises two layers of conductive glass and a plurality of liquid crystal molecules located between the two layers of conductive glass, the liquid crystal molecules form a plurality of liquid crystal micro lenses arranged in an array, and the conductive glass is provided with electrodes; when the two layers of conductive glass are in a power-on state, liquid crystal molecules deflect, so that the phase of incident light is changed, a display picture is imaged at any position in a space from the surface of the side, facing the liquid crystal micro-lens layer, of the glass cover plate to the side, away from the liquid crystal micro-lens layer, of the glass cover plate, the picture can be displayed in a regional floating mode, the display effect is enriched, a paper-like effect is achieved during human eye watching, and comfort and nature are achieved.

Description

technical field [0001] The present application belongs to the field of display technology, and more specifically relates to a display device based on a liquid crystal microlens array. Background technique [0002] The LCD (Liquid Crystal Display) display module is composed of a backlight module, a FOG (FPC onglass) module, and a glass cover. The backlight module provides a uniform surface light source for the LCD display, and the FOG module is from top to bottom It is mainly composed of an upper polarizer, an upper glass plate, a color filter layer, a liquid crystal layer, a TFT (Thin Film Transistor, thin film transistor) layer, a lower glass plate, and a lower polarizer in sequence. In order to realize the picture display, the unpolarized light emitted by the backlight module becomes polarized light after passing through the lower polarizer, and the liquid crystal molecules in the liquid crystal layer can change the polarization angle of the polarized light, and the polari...
