AI Technical Summary

Problems solved by technology

If each viewpoint pixel is designed to be the size of the original pixel, then the area of ​​each pixel is four times the original pixel area, not only the display resolution is greatly reduced, but also in the use of near-eye display, because the screen is very close to the human eye, Pixel patterns are easily discernible by the human eye, so they can greatly affect the display
If the original pixel is divided into 4 parts, then the area of ​​each viewpoint pixel is 1 / 4 of the original pixel area. Although it will not affect the display resolution and display effect, it is difficult to achieve an effective pixel size due to the current technological level. decrease

Abstract

Embodiments of the present invention provide a near-eye display device and a near-eye display method. The near-eye display device includes a light source device, a light guide device, a display panel and a light splitting device. The light source device is used to sequentially emit multiple monochromatic lights, and the light of each monochromatic light is incident on the light guide device at a set angle; the light guide device It is used to make the light incident on the display panel at the set position; the display panel is used to control the color and gray scale of the light emitted by each pixel; the light splitting device is used to make the light emitted by each pixel respectively directed to multiple viewpoints of the human eye. In the present invention, by setting a light source device that generates a variety of monochromatic light, the light is incident on the light guide structure of the display panel at a set position, the display panel that controls the color and gray scale of the light emitted by each pixel, and controls the direction of light emission. The controlled light splitting device not only realizes the near-eye display of single-eye multi-viewpoint, but also greatly improves the display resolution.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a near-eye display device and a near-eye display method. Background technique [0002] In recent years, virtual reality (Virtual Reality, VR) / augmented reality (Augmented Reality, AR) devices have been gradually applied to fields such as display, games, and medical care, and near-eye display technology has received more and more attention and research. At present, the near-eye display device used to realize 3D display usually divides the display screen into left and right display areas, the left display area displays the image for the left eye, and the right display area displays the image for the right eye, by displaying the same scene in the left and right display areas Different parallax images, using binocular parallax to achieve 3D display effect. Since this near-eye display device utilizes binocular parallax, the focus position of the single eye is on the display screen i...
