Display spectacles and driving method thereof

Abstract

The invention discloses display spectacles and a driving method thereof. The display spectacles comprise two display devices arranged on a spectacle frame to serve as lenses. Each display device comprises a backlight source, a lower substrate located on the light outlet side of the backlight source, an upper substrate opposite to the lower substrate, a liquid crystal layer located between the upper substrate and the lower substrate, a polaroid located between the lower substrate and the backlight source, and a plurality of groups of electrode structures and a control unit located between the upper substrate and the lower substrate. During displaying, each group of electrode structures is used for controlling liquid crystal molecules in the corresponding area in the corresponding liquid crystal layer to deflect to form a microprism structure; the control units are used for adjusting the voltage of each group of electrode structures so as to control the microprism structures to conduct total reflection or refraction on light emitted by the backlight source, and then the display gray scale is adjusted. According to the display spectacles, the transmission path of outgoing light of the lenses is controlled through the microprism structures so that the display angle of the lenses can be controlled, and the display spectacles can be used for watching a wearable display device with large visual angle and small 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.
