Microdisplay company Kopin Corporation has developed what it says is the world’s first ultrahigh-brightness (over 35,000 nits), high-dynamic-range (HDR), green Organic Light Emitting Diode (OLED) microdisplay on silicon, designed for high-performance augmented reality applications.
The microdisplay includes a unique patent-pending pixel structure and backplane architecture for super-high dynamic range operation (14 bits).
According to Kopin, the new microdisplay is ideal for use in ambient scenes ranging from very dark night to very bright daylight. Its duo-stack structure provides increased current efficiency, which leads to much higher brightness, lower power consumption (about half of that of LCD displays of equivalent brightness), and longer lifetime compared to conventional single-stack OLED devices.
“The achievement of very high brightness and long lifetime coupled with an extremely wide luminance range is a culmination of the OLED technology we have been developing over the past several years,” said Dr. John CC Fan, CEO of Kopin.
“The performance levels of the initial builds of this display, which we believe have never been achieved before in OLED microdisplays, is a major milestone in the development of our displays targeted for emerging AR and VR applications. We are working to achieve much higher brightness approaching 100,000 nits.”
