Problems solved by technology

However, when using virtual reality glasses, the eye muscles are prone to fatigue due to the difference in the amount of focal length that the eyes have to change, the focal length of the matching optical elements, and the changing distance of virtual objects.
In this way, it will cause obvious discomfort to the user, and a good user experience cannot be obtained

Abstract

The invention provides a head-mounted display device. The head-mounted display device comprises an eye movement tracking module, a focusable imaging module and an image generating module, wherein the eye movement tracking module is used for detecting eye movement of a user to obtain eye movement tracking information. The focusable imaging module includes a plurality of imaging layers in an overlapping configuration. Each of the imaging layers includes a liquid crystal layer and a linear reflective polarizer. The image generating module is used for receiving an image signal and generating a polarized image light beam to the focusable imaging module. The image generation module determines one of the imaging layers to be in a reflection state and the other imaging layers to be in a transmission state according to the eye movement tracking information so as to reflect the polarized image beam to the viewing position through the imaging layer in the reflection state.

Description

technical field [0001] The present invention relates to a display device, in particular to a head-mounted display device (Head-Mounted Display) applied to virtual reality (Virtual Reality, VR). Background technique [0002] With the advancement of technology, traditional flat display devices are no longer able to satisfy general consumers. In order to provide users with more realistic and three-dimensional visual entertainment, virtual reality has become a new trend in display technology. The principle of virtual reality is to construct a virtual space, and each virtual object in the virtual space has a specific distance from the user. [0003] Currently, head-mounted virtual reality display devices, such as virtual reality glasses, are widely used. The virtual reality glasses will respectively display different images with perspective difference to the user's left eye and right eye. By making the eyes of two eyes intersect to view a single object, the user can have a thr...
