Problems solved by technology

However, due to the conflict between the convergence rotation of the human eye and the constant diopter adjustment (convergence conflict), viewers are prone to eye fatigue and dizziness when they continue to watch dynamic 3D images.

Abstract

The invention relates to an optical display system and a display device. The optical display system comprises M display screens, M lenses and an optical waveguide; the focal lengths of at least two lenses in the M lenses are different, wherein M is a natural number greater than 1; the optical waveguide comprises an optical waveguide body and a light output part. The M display screens are in one-to-one correspondence with the M lenses, and the lenses are configured to transmit light from the corresponding display screens to the optical waveguide body for transmission; the light output part is configured to output the light from the M display screens from the optical waveguide body for imaging, the light from the same display screen forms the same image, the light from the M display screensforms M images, and at least two image distances in the image distances of the M images are different. According to the embodiment of the invention, eye fatigue and dizziness can be relieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an optical display system and a display device. Background technique [0002] When we watch a three-dimensional object, a three-dimensional display image can be formed in the brain. The principle is that the left and right eyes respectively see pictures of the same scene at different angles of view, and these two pictures cause the parallax of the left and right eyes. The brain is able to integrate images from the two viewpoints into a stereoscopic image. [0003] During the viewing process, the two eyes adjust the diopter through the lens respectively, so that the image of the object is focused on the virtual image plane of the retina. When the brain integrates images, due to the depth difference between the three-dimensional object and the virtual image plane, the eyes need to perform vergence rotation to adapt to this depth difference. Based on the muscle memory of human e...
