Abstract: A driving method is configured to drive a display device, and the display device includes a display array and a light valve array. The display array includes rows of sub-pixels, the light valve array includes a plurality of sub light valves, a respective one sub light valve of the plurality of sub light valves corresponds to at least one row of sub-pixels, and the light valve array is on a light-emitting side of the display array. The driving method includes: any sub-pixel in the at least one row of sub-pixels being in a response phase of a display operation, the respective one sub light valve being in a light-shielding state, and the respective one sub light valve corresponding to the at least one row of sub-pixels.

Abstract: The present disclosure is related to an image processing method of virtual reality. The image processing method may include obtaining position information of a gaze point; performing a compression process on an original image to obtain a compressed image based on the position information of the gaze point; performing a compression process on a distorted image of the original image in an lens to obtain a compressed distorted image based on the position information of the gaze point; and performing an anti-distortion process on the compressed image to obtain an anti-distortion image based on a relationship between the compressed image and the compressed distorted image. The position information of the gaze point may be position information of a gaze point of a user's eye on an original image.

Abstract: The present disclosure proposes a dual-screen display method for eliminating AR/VR picture tearing and an AR/VR display device, each single screen in a dual-screen for the dual-screen display method being divided into a first half-screen and a second half-screen respectively. The method includes: performing rendering and scanning in parallel for the first half-screen and the second half-screen in unit of half a frame. A start time of scanning the second half-screen is adjusted to eliminate a picture tearing phenomenon.
