Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0036] An embodiment of the present invention provides a display control method, which is applied to a head-mounted display device. The head-mounted display device includes a graphics card, a display screen, and a liquid crystal light valve. The liquid crystal light valve is located on the near-eye side of the display screen. There are multiple gratings on the valve, and each grating can be independently controlled to change the light transmission state of the grati...

Abstract

The invention discloses a display control method and head-mounted display equipment. The display control method is applied to the head-mounted display equipment. The head-mounted display equipment comprises a display card, a display screen and a liquid crystal light valve, wherein the liquid crystal light valve is located at a near-to-eye side of the display screen. The display control method comprises the steps of detecting a vertical synchronization signal outputted by the display card; and displaying a current frame image in a frame buffer memory of the display card on the display screen based on the vertical synchronization signal, and sequentially controlling multiple Bragg gratings on the liquid crystal light valve to be adjusted from a non-transparent state to a transparent state. The display control method is used for improving the delay of a low-refresh-rate LCD screen, and avoids the phenomena of smearing and blurring of the LCD screen.

Description

technical field [0001] The present invention relates to the field of image display, in particular to a display control method and a head-mounted display device. Background technique [0002] In VR (Virtual Reality; virtual reality) technology, the screen display is a very important part. VR displays the virtual picture through the screen. Due to the limitation of the screen refresh rate, the screen will have a certain delay, and the screen delay will be serious. affect the user experience. Generally speaking, if the screen delay exceeds 20ms, it will easily lead to smearing and blurring on the screen. [0003] In the prior art, the following two solutions can be used to solve the problem of excessive screen delay. [0004] The first solution is to increase the refresh rate of the screen. Because the screen delay depends to a large extent on the refresh rate of the display screen, the higher the refresh rate, the smaller the screen delay. world. [0005] However, achievi...
