Abstract

An embodiment of the present disclosure provides a display device, including: a light source, a light splitting device, a first image source, a second image source, and an image synthesis device. The light splitting device is located in front of the light source, and is used for splitting the light emitted from the light source into a first light ray and a second light ray. The first image source is located on the optical path of the first light, and is used for modulating the first light to project a first image to be displayed on the first focal plane. The second image source is located on the optical path of the second ray for modulating the second ray to project a second image to be displayed on the second focal plane, wherein the focal length of the first focal plane is longer than that of the second focal plane Short focal length. The image synthesizing device is located in front of the projection of the first image and the second image, and is used for synthesizing the first image and the second image into a synthetic image and displaying it to the user. A method for arranging the above-mentioned display device is also provided.

Description

technical field [0001] The present disclosure relates to the field of imaging, and in particular to display devices and methods of arranging them. Background technique [0002] Portable displays, such as head-mounted displays, are becoming more and more popular. Including augmented reality glasses and virtual reality helmets, the optical systems used by the head-mounted displays currently on the market are all single-focal plane, that is, there is only one virtual image formed by the optical system in front of the user's eyes, and the virtual image and The user distance is fixed. When the user uses the head-mounted display, the user may experience dizziness, nausea or even headaches when observing scenes that are relatively close to the user, which greatly reduces the comfort of the head-mounted display. [0003] Therefore, there is a need for a display that enables a user to comfortably observe scenes at different distances. Contents of the invention [0004] An aspect...
