Document Type and Number:
WIPO Patent Application WO/2023/220947
Kind Code:
A1
Abstract:
The present invention relates to the field of image display, and in particular to a defocus display system. The defocus display system comprises: a first image source presenting a first image; a second image source presenting a second image; and an optical path system comprising at least one optical imaging device. The optical path system is opposite to the first image source and forms a first image having a first imaging distance for the first image source; the optical path system is opposite to the second image source and forms a second image having a second imaging distance for the second image source; the second imaging distance is greater than the first imaging distance, wherein the optical path system further comprises an observation interface which corresponds to the first image and the second image, such that the first image and the second image can be observed at the same time by means of the observation interface. According to the defocus display system, the imaging distance of more than two images can be respectively adjusted in a targeted manner, such that the defocus display system generates defocus stimulation on an observer to inhibit the elongation of an ocular axis.
