Abstract

The invention provides a virtual reality display device. The virtual reality display device includes a display device and a lens system. The display device includes multiple pixel units. The lens system is provided with multiple different optical axes at different time periods. In the different time periods, the multiple pixel units form multiple pixel virtual images through the different opticalaxes. The invention also provides a driving method of the virtual reality display device. The virtual reality display device and the driving method thereof provided by the invention enable the pixel units of the display equipment to generate the different pixel virtual images at the different time periods by arranging the optical axes located at different positions of the lens system in the multiple time periods. When the multiple time periods are quickly switched, a visual effect that resolution is multiplied is formed.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a virtual reality display device capable of improving resolution and a driving method thereof. Background technique [0002] VR (Virtual Reality, virtual reality) display was proposed in the 1980s. It integrates computer graphics technology, computer simulation technology, sensor technology, display technology and other science and technology. It creates a virtual information environment in the multi-dimensional information space. It can enable users to have an immersive sense of immersion, have a perfect interaction ability with the environment, and help to inspire ideas. A virtual reality display device in the prior art generally includes a computer processing system, an image processing system, a display panel, and an optical system. Among them, the computer processing system captures the character's behavior and the external environment through external sensors, and then pr...
