Abstract

The invention provides a virtual reality display device. The device includes an OLED display panel and an optical system. The optical system is arranged between the OLED display panel and a user observation side. The optical system includes a first linear polarizer arranged between the OLED display panel and the user observation side, a first reflective and transmissive optical film arranged between the first linear polarizer and the OLED display panel and a first 1 / 4 wave plate arranged between the first reflective and transmissive optical film and the OLED display panel. According to the invention, through the arrangement of the first reflective and transmissive optical film and the first 1 / 4 wave plate, linear polarized light which cannot pass through the first liner polarizer is converted into linear polarized light which can pass through the first liner polarizer to enter the subsequent optical system, which improves the optical utilization of the virtual reality display device and improves the display brightness of the virtual reality display device.

Description

technical field

[0001] The invention relates to the field of display technology, in particular to a virtual reality display device. Background technique

[0002] VR (Virtual Reality, virtual reality) display was proposed by Jaron Lanier, the founder of the American VPL company in the 1980s. It integrates computer graphics technology, computer simulation technology, sensor technology, display technology and other science and technology. Creating a virtual information environment on the information space can enable users to have an immersive sense of immersion, have a perfect interaction ability with the environment, and help to inspire ideas.

[0003] 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 processes according t...
