According to the China Patent Publication Announcement of the State Intellectual Property Office (Application Publication No.: CN115407504A), the patent application for a virtual display device and virtual display method applied by Huawei Technologies Co. Ltd. was announced.
The abstract shows that this embodiment can avoid problems such as vergence and adjustment conflicts in the process of providing virtual display functions, thereby avoiding human eye fatigue.
The specific solution is: the first optical display module is used to realize the following functions under the control of the processor: display the first object, the depth of convergence of the first object is the first depth of convergence, and the first optical display module The imaging surface depth is the first depth. The second object is displayed, the depth of convergence of the second object is the second depth of convergence, and the depth of the imaging plane of the first optical display module is the second depth. When the first depth of convergence is different from the second depth of convergence, the optical display module adjusts the difference between the first depth and the second depth.
Video terminals such as computers, TVs, and mobile phones are an indispensable part of modern life, and after long-term use, it is easy to cause eye fatigue. Generally speaking, reading, playing games, watching the computer, etc. should not exceed one hour. Looking from a distance or looking at the green plants afterward is not only beneficial to the relief of visual fatigue but also beneficial to physical and mental health.
