In conventional VR displays, there has been a trade-off between the field of view and resolution. Expanding the field of view results in a decrease in pixels per degree (ppd), sacrificing image clarity.

In this study, we propose a new approach to overcome this limitation by combining multiple lenses and displays. Specifically, we achieved a 220-degree wide field of view using two optical lenses. However, this configuration alone results in a low overall resolution of 10 ppd. To address this, we placed a 4K resolution Micro OLED display behind a half-mirror in the center of the field of view, achieving a high resolution of 110 ppd in the central area.

By applying precise calibration and image processing to minimize the visibility of boundaries, we have made it possible to experience a seamless single image. Additionally, we developed a 32K resolution video player and OpenXR runtime, making application development easier.
