Abstract

This application discloses a dual-screen display method and AR / VR display device that eliminates AR / VR screen tearing. It is used for display where the rendering time of each frame is greater than the scanning time, including: dividing each single screen of the dual screen into For the first and second half-screen scans, parallel rendering and scanning are performed in half-frame units, and the second half-screen is the back-scan screen; by adjusting the start time of the second half-screen scan, the screen tearing phenomenon is eliminated. According to the technical solution provided by the embodiment of the present application, the problem of screen tearing can be solved by adjusting the starting time of the second half-screen scan or the second screen scan.

Description

technical field [0001] The present disclosure generally relates to the display field, and in particular relates to a dual-screen display method and an AR / VR display device for eliminating tearing of AR / VR screens. Background technique [0002] VR systems are usually used in fields such as games and video playback, and scenes are switched frequently. In order to increase the visual fluency of users, the display refresh rate is usually greater than 90HZ. Since it takes a few milliseconds for the liquid crystal to respond, smearing will occur due to the untimely liquid crystal response when scenes are switched at high speed, which seriously affects the VR user experience. At present, the method of turning off the backlight when the liquid crystal responds, and turning on the backlight after the response is over is more effective. This method is called backlight insertion black. [0003] When using dual LCD displays and black insertion technology, the screen scanning time is co...
