Kopin Announces ColorMax™ Technology for 1.3” 2.6K x 2.6K OLED Micro Display
July 05, 2020
Kopin announced its latest Lightning® 1.3” 2.6K x 2.6K OLED display (2560 x 2560 resolution) with > 115% sRGB. Kopin uses duo-stack OLED micro displays aimed at high-performance virtual reality/augmented reality/mixed reality (VR/AR/MR) headsets. A duo-stack OLED is two OLED structures on top of each other and connected in a series so that carriers (electrons-holes) pass through the duo-stack OLED and generate photons twice, instead of the conventional single-stack OLED structure currently used in OLED micro displays. Kopin claims their duo stack increases luminance by 4x, while lowering power consumption and increasing lifetime, although they released no supporting measurement data. Previous duo-stack OLED structure introduced color mixing among subpixels, resulting in unacceptable color performance. Kopin’s patent-pending innovation incorporates a specially configured anode structure in the Si backplane to suppress the color mixing. The Duo stack is grown in one step in the OLED chamber, so the additional delta cost is very small compared to cost of single stack .
The display integrates high-speed D-PHY/C-PHY MIPI interface and Display Stream Compression (DSC) circuits to handle compressed video of up to 3:1 ratio. The new micro display has 10-bit color control, the world’s first in OLED micro displays according to Kopin. The 10-bit color control, together with the high color fidelity, efficiency (> 6 candela/ampere), high brightness level (> 1000 nits) and high contrast ratio (> 10,000: 1), enables studio-quality, high dynamic range (HDR) capable VR experience. The results were obtained collaboration with foundry partner, Lakeside Optoelectronic Technology Co., Ltd. Further improvements in the brightness (> 2000 nits) and color fidelity are expected through optimization of OLED deposition process. By incorporating a structure to enhance the output coupling efficiency, Kopin believes it can achieve > 5000 nits within a couple of years.
Kopin touts the design of the backplane requiring integration of many different functional blocks including digital memory, Driver IC (DDIC) and System on Chip. The second generation 2.6K x 2.6K includes 120-Hz frame rate with global shutter and reduced power consumption which will be commercially available to select partners in 2021.” From: Insight Media
