Problems solved by technology

[0004] During the production and assembly process, foreign matter such as dust, dander, and fiber debris may fall between the display screen and the lens group, causing the human eye to observe the display screen through the optical imaging system. The foreign matter will be imaged, resulting in black spots and black lines , Bright spots, bright lines, etc. are poorly displayed

Abstract

The invention provides an optical imaging system and a head-mounted display device. The optical imaging system comprises a display screen and a lens group, the display screen is located on the side, away from the human eyes, of the lens set and comprises a display panel and a cover plate, the cover plate is arranged on the side, facing the lens set, of the display panel, and the thickness range of the cover plate is related to the equivalent image space focal length of the lens set, the refractive index of the cover plate and the photopic vision distance of the human eyes. The invention provides an optical imaging system and a head-mounted display device, which can enable poor display caused by foreign matters between a display screen and a lens group not to be easily perceived by human eyes.

Description

technical field [0001] The present application relates to the field of optical technology, in particular to an optical imaging system and a head-mounted display device. Background technique [0002] Virtual Reality (VR) refers to the projection of digital content to the human eye through an optical imaging system, allowing users to feel as if they are in a virtual world to achieve an immersive virtual experience. With the continuous development of VR technology, users can use the head-mounted display device to see pictures in the virtual world, and the optical imaging system is a key component in the head-mounted display device. [0003] The optical imaging system includes a display screen and a lens group. The light emitted by the display screen is refracted by the lens group and enters the pupil of the human eye. The reverse extension of the light entering the through hole of the human eye converges in the distance to form a virtual image. The image is the virtual image, ...
