Title:
EYEPIECE SYSTEM AND NEAR-EYE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/022407
Kind Code:
A9
Abstract:
An eyepiece system (10) and a near-eye display device. The eyepiece system (10) comprises a plurality of lenses sequentially arranged along the same optical axis from an image side to an object side, the refractive indexes of the plurality of lenses are all greater than 1.65, and the total track length (TL) of the plurality of lenses along a main optical axis is less than or equal to 25 mm. Given that the eyepiece system (10) has high refractive power, the total track length of the plurality of lenses is reduced, thereby ensuring that the eyepiece system (10) has a relatively high imaging quality and also achieving the miniaturization of the eyepiece system (10).
