Head-mounted display device based on liquid crystal lens array

Abstract

The invention provides a headset display device based on a liquid crystal lens array, relating to the stereo display technology field. The headset display device comprises a display screen and a liquid crystal lens array which is arranged in the front of the display screen and opposite to the human eye; the crystal liquid lens array comprises a plurality of liquid crystal lenses; the plurality of liquid crystal lenses are arranged in M rows and N lists; the liquid crystal lens comprises a first glass substrate and a second glass substrate which are arranged in opposition; the first glass substrate is coated with level electrodes; the second glass substrate is coated with n annular electrodes which are arranged in a concentric ring manner; and liquid crystal is filled between the first glass substrate and the second glass substrate. Each liquid crystal lens in the liquid crystal array is adjustable, which can regulate the whole part or the local part of the display screen and performs 2D or 3D displaying through partitioning, and the definition is adjustable. The invention can perform scene dynamic zooming according to the different display content, and can realize the human eye initiative selection and focusing.

Description

technical field [0001] The invention relates to the technical field of stereoscopic display, in particular to a head-mounted display device based on a liquid crystal lens array. Background technique [0002] The head-mounted 3D display device has good portability, and plays an irreplaceable role in both life entertainment and medical industry. Head-mounted 3D display devices can enjoy 3D video and game entertainment anytime and anywhere. Engineers can see architectural drawings during work, and maintenance personnel can see installation instructions. Doctors can see the patient's major organs, MRI, and X-ray scans during the operation. Therefore, it is of practical value to develop a head-mounted integrated imaging 3D display device. [0003] The current mainstream head-mounted virtual reality (VR) display device displays two images with parallax in the left eye and the right eye. The left eye sees the left viewpoint image, and the right eye sees the right viewpoint image,...

AI Technical Summary

Problems solved by technology

[0004] In the existing head-mounted virtual reality (VR) display device, the liquid crystal lens and the multi-dimensional whole lens used can only realize the overall adjustment, but cannot realize the partial adjustment of the area of ​​the display screen.

In addition, the current liquid crystal lens structure can provide users with a relatively narrow field of view, and users can only watch from a small angle. In this case, users are prone to eye swelling or eye fatigue and other discomfort symptoms over time.

[0005] At the same time, users with different eyesight will see different images when wearing VR display devices.

The same picture is very clear for users with normal eyesight, but it will be blurred for users with nearsightedness or farsightedness, and the effect of the picture seen by users with different degrees of myopia or hyperopia will also be different. During the viewing process, it is impossible to find a suitable viewing point or feel dizzy, which affects the overall experience. This is another difficulty in the popularization of VR display devices
