Problems solved by technology

[0003] In the existing spatial multiplexing light field display, the microlens array projects the light field sub-images of the panel display into the user's retina, and the user can see a virtual light field image composed of many sub-images stacked on top of each other. When the user looks at the microlens array along different viewing angles, the light field image at a large viewing angle will be blurred, and the blurring phenomenon will become more and more obvious when the viewing angle is larger, which leads to the existing spatial multiplexing method. Poor optical quality of light field displays

Abstract

A near-eye light field display device comprises a first lens, a micro lens array, a second lens and a display panel. The display panel is used for providing an image light beam. The eye side surface of the micro-lens array is provided with a plurality of eye-side micro-lenses, and the display side surface of the micro-lens array is provided with a plurality of display-side micro-lenses. The multiple eye side micro lenses are arranged at equal intervals according to a first interval, the multiple display side micro lenses are arranged at equal intervals according to a second interval, and the first interval is different from the second interval. The near-eye light field display device provided by the invention has good display quality.

Description

technical field [0001] The present invention relates to a display device, and in particular to a near-eye optical field display device. Background technique [0002] Generally speaking, light field displays can be divided into two types: spatial multiplexing and time multiplexing. Time-multiplexed light field displays use micro-electromechanical elements to change the position of virtual images to adjust the clarity of the front and back scenes. The spatially multiplexed light-field display uses display elements such as Micro-LED, Micro-OLED, and LCD to pass the light-field sub-image through optical elements, such as : Micro-lens array (Miro-LensArray), and the parallax image is stacked on the retina, so that the user can watch the light field image with depth. [0003] In the existing spatially multiplexed light field display, the microlens array projects the light field sub-images of the panel display into the user's retina, and the user can see a virtual light field ima...
