Kopin Shipping Commercial Versions of Its 1280 X 720 Duo OLED Micro Display
Kopin received an order from a US company is for public safety applications for its 0.5” Duo OLED micro display. The 12.5mm diagonal display uses a dual stack OLED structure for high current efficiency of 10Cd/A. Kopin’s ColorMax technology provides average color fidelity of over 90% sRGB. The duo-stack display has two OLED structures on top of each other and connected in series. As a result, a voltage increase is share equally between the two OLED layers generating twice the luminance of a single stack with the same current. The backplanes are made at foundry partner, Lakeside Optoelectronic Technology in China. This initial order, although quite modest is an important milestone for Kopin’s OLED micro display business, and proof of their fabless OLED display model, Lakeside, manufactures the displays on our ColorMax backplane wafers to meet Kopin specifications. ColorMax uses a specially configured anode structure in the silicon backplane to suppress color mixing among tiny sub-pixels in the display that measure just 2.8μm x 8.4μm which otherwise would be severe for duo-stack structures.
Almost concurrently, Kopin®Corporation announced a multi-year agreement with Jade Bird Display (JBD), to develop monochrome MicroLED micro displays. Jade Bird Display will provide the LED wafers and the hybrid bonding service on Kopin-designed and Si backplane wafers from Lakeside Optoelectronic Technology for monolithic 2K x 2K MicroLED micro displays (2048 x 2048 resolution in about 1” diagonal size). The combination of JBD monochrome micro display and Kopin’s designed backplanes significantly reduces the time-to-market for monochrome MicroLEDs that can purportedly deliver 2m cd/m2.
