Abstract

The invention relates to a VR eyepiece system, and the system comprises a lens assembly which comprises a first lens, a second lens, a third lens and a fourth lens which are sequentially and coaxially arranged from the eye side to the image side; the quarter-wave plate is attached to the image side surface of the polarization reflection film; the semi-transparent and semi-reflective film is attached to the image side surface of the third lens; the display assembly is arranged on the image side surface of the fourth lens; the VR eyepiece system satisfies the following relational expressions: 1.35 lt; the method is characterized in that TTL * tan (SEMI-FOV) / IMGhlt; 1.6); wherein TTL is the on-axis distance from the eye side face of the first lens to the display assembly, SEMI-FOV is the half field angle of the VR eyepiece system, and IMGh is half of the diagonal length of an effective pixel area on the image plane of the VR eyepiece system. According to the VR eyepiece system, by designing the ratio relation among the multiple key parameters, the imaging quality can be optimized, the comfortable visual experience can be provided, and the eye fatigue feeling of a user during long-time use can be reduced.
