Problems solved by technology

[0003] In the optical system of the virtual display, a projection lens is needed to transmit light beams. However, the projection lens is easily affected by the heat generated by other components in the optical system, causing thermal expansion and contraction, which leads to the shift of the focal point of the projection lens. , which in turn causes blurring of the final displayed picture

Abstract

The invention provides a virtual display. The virtual display comprises an optical assembly, a heat dissipation part and a heat conduction assembly, wherein the optical assembly comprises a projectionlens; the heat dissipation part is arranged on one side of the projection lens; and the heat conduction assembly is arranged between the projection lens and the heat dissipation part, and when the heat conduction assembly is in contact with the projection lens and the heat dissipation part, the heat conduction assembly is used for transmitting heat on the projection lens to the heat dissipation part. According to the virtual display, the stability of the display effect of the virtual display can be improved.

Description

technical field [0001] The present disclosure relates to the field of virtual displays, in particular to a virtual display. Background technique [0002] Virtual displays, such as AR (Augmented Reality, Augmented Reality) glasses, VR (Virtual Reality, Virtual Reality) glasses and MR (Mixed Reality, Mixed Reality) glasses often add virtual scenes to real scenes when they are working; A good visual experience has high requirements on the effect of virtual display. [0003] In the optical system of the virtual display, a projection lens is needed to transmit light beams. However, the projection lens is easily affected by the heat generated by other components in the optical system, causing thermal expansion and contraction, which leads to the shift of the focal point of the projection lens. , which in turn causes blurring of the final displayed picture. [0004] The above information disclosed in this Background section is only for enhancement of understanding of the backgrou...
