AI Technical Summary

Technical Problem

The indicator lights on existing head-mounted display devices have poor illumination, resulting in a poor visual experience for users.

Method used

The design employs a light-emitting element located inside the cavity and a light guide plate located at the opening. Light enters the light guide plate through the light-incident surface and is refracted and reflected at the light-out surface, achieving uniform light output. Combined with an optical dot structure and a reflective film, the light utilization rate is improved.

Benefits of technology

It improves the uniformity and utilization of light, enhances the visual experience and the aesthetics of the device, and provides better display effects and ease of operation.
