A kind of display glasses and its driving method

Abstract

The invention discloses display glasses and a driving method thereof, comprising two display devices arranged on the glasses frame as lenses; the display device includes a backlight source, a lower substrate located on the light emitting side of the backlight source, and an upper substrate opposite to the lower substrate , a liquid crystal layer located between the upper substrate and the lower substrate, a polarizer located between the lower substrate and the backlight source, multiple sets of electrode structures and a control unit located between the upper substrate and the lower substrate. When displaying, each group of electrode structures is used to control the deflection of liquid crystal molecules in the corresponding regions of the liquid crystal layer to form a microprism structure; Reflect or refract, so as to realize the adjustment of display gray scale. The above-mentioned display glasses control the transmission path of light emitted by the lens through the formed microprism structure, thereby controlling the display angle of the lens, which can adapt to the characteristics of wearable display devices with a large viewing angle and a short viewing distance.

Description

technical field [0001] The invention relates to the field of display technology, in particular to display glasses and a driving method thereof. Background technique [0002] Existing liquid crystal display panels generally include an array substrate and a color filter substrate arranged opposite to each other, a liquid crystal layer, a common electrode and a pixel electrode located between the array substrate and the color filter substrate, and polarizers respectively located on the array substrate and the color filter substrate. . [0003] The display principle of the existing liquid crystal display panel is to convert natural light into linearly polarized light through the polarizer on the array substrate, apply voltage to the pixel electrode and the common electrode to form an electric field on both sides of the liquid crystal layer, and the liquid crystal molecules in the liquid crystal layer are under the action of the electric field Rotation occurs, thereby changing t...

AI Technical Summary

Problems solved by technology

[0004] Due to the characteristics of the wearable display, the viewing distance of the human eye to the display lens is relatively short and the viewing angle is large, when the existing liquid crystal display panel is used as the eyeglass lens to make display glasses, the display effect is not ideal.
