AI Technical Summary
Existing head-mounted displays struggle to achieve high-resolution image display, and also suffer from issues such as large optical module thickness and low light output efficiency.
The system employs a doublet lens structure, including first and second lenses with different average curvatures on the lens surfaces, and uses a combination of polarizing film and phase retardation film to optimize the optical path, thereby reducing thickness and improving light output efficiency.
It achieves high-resolution image display on the display device, while reducing the thickness of the optical module and improving light output efficiency.
