Advanced Study of Optical Imaging Systems for Virtual Reality Head-Mounted Displays

Abstract

Driven by the rapid innovation of science and technology and industrial manufacturing technology, virtual reality display technology has developed rapidly. At present, the application of virtual reality display technology is expanding in many fields such as military, medical, aviation and education. This paper analyzes the imaging principle of the human vision system and the optical performance requirements of VR heads-up display, summarizes the current design scheme of VR heads-up optical imaging system, focuses on the principle and index parameters of each optical system, and compares the advantages and disadvantages of different schemes. The development prospects and directions of virtual reality headset displays are also prospected.

High‐luminance, large‐size 4K OLED microdisplays for VR/MR applications

“…Additionally, increasing panel brightness is a crucial factor in head-mounted devices with modern pancake lenses, which have significantly low optical efficiencies. [9][10][11][12][13] Although the pancake lens may be inefficient for the luminance of microdisplays, it may be necessary to use such optical elements in VR/MR headsets because they can reduce the space required between the display and the lens, allowing for more compact glasses in VR/MR head-mounted devices. Our full-color OLED microdisplay panel exhibits sufficiently high brightness, exceeding 10,000 nits, to overcome the high loss of the optical system used.…”
