Abstract
The invention discloses a VR optical system, the VR optical system comprises a light path folding module, and a first light-emitting assembly and a second light-emitting assembly which are arranged on the peripheral side of the light path folding module, the first light-emitting assembly emits a first optical image towards the light path folding module along a first direction, the first optical image is emitted to a development area along a third direction, and the second light-emitting assembly emits a second optical image towards the development area along a fourth direction. The second light-emitting assembly emits a second optical image towards the light path folding module in the second direction, and the second optical image is emitted to the development area from the light path folding module in the fourth direction and is overlapped with the first optical image in the development area; the light path folding module is configured to change the angle of the second included angle by changing the angle of the first included angle, so that the overlapping area of the first optical image and the second optical image is adjusted. Compared with the prior art, the VR optical system provided by the invention can reduce the screen window effect and improve the display effect of the display picture.
Description
technical field [0001] The invention relates to the technical field of virtual reality display devices, in particular to a VR optical system. Background technique [0002] Virtual reality technology (English name: Virtual Reality, abbreviated as VR) is a new practical technology developed in the 20th century. Virtual reality technology includes computer, electronic information, and simulation technology. Its basic implementation method is to simulate a virtual environment by computer to give people a sense of environmental immersion. [0003] In the existing VR equipment, there are two main optical solutions, one is the Fresnel single lens solution, which is low in cost, but the imaging resolution is low and the total optical length is longer; the other is the folded ultra-short focus optical path, The total optical length is about double that of the Fresnel single lens solution, but due to the optical system, the light utilization rate is less than 20%, so the projection b...
