Kopin and Goertek Collaborate on OLED Microdisplay Driven VR Headset
June 5, 2017
Kopin Corporation showcased a groundbreaking reference design, codenamed Elf VR, for a new Head-Mounted Display created with its partner Goertek Inc. (“Goertek”). To resolve the issues of bulky and heavy headsets, low resolution and sluggish frame rates causing screen door effect and nausea, Kopin’ engineers created “LightningTM” The OLED microdisplay panel has 2048 x 2048 resolution in each eye, more than three times the resolution of Oculus Rift or HTC Vive, and at a pixel density of 2,940 pixels per inch. The panel runs at 120Hz refresh rate, 33% faster than what traditional HMDs offer - for reduced motion blur, latency and flicker. Kopin’s has integrated driver circuits, and requires much less power, so battery life can be extended, and heat output is substantially reduced. It is lighter and fully 40% smaller than standard solutions, so that it can be worn for long periods without discomfort. In addition to the new design, Kopin previously announced an alliance with BOE Technology Group Co. Ltd. (BOE) and Yunan OLiGHTEK Opto-Electronic Technology Co., Ltd. for OLED display manufacturing. The Microdisplay panels are manufactured with advanced ultra-precise processing techniques. Its pixel density was increased by approximately 400% compared to the conventional TFT-LCD, OLED and AMOLED display, and the screen size can be reduced to approximately 1/5 at similar pixel resolution level. Elf VR adopts an advanced optical solution with a compact Multi-Lens design, which enabled it to reduce the thickness of its optical module by around 60%, and to reduce the total weight of VR HMD by around 50% as well, which can significantly improve the user experiences for longtime wearing. The reference design supports two novel optics solutions – 70 degrees FOV or 100 degrees FOV for deep immersion.
