OmniVision Technologies describes its OP02220 as the industry’s first 1080p liquid crystal on silicon (LCOS) micro display with integrated driver functions and memory. It is deemed valuable for augmented reality (AR) applications such as glasses and head-mounted displays that need durability, compactness and lightweight. Sam Yoshikawa, product marketing manager at OmniVision, says, “A single-chip LCOS architecture is not only perfect for compact and lightweight systems, but it is also capable of reducing heat and extending battery life through lower power consumption, which are all key requirements for the next generation of AR glasses. These AR glasses and other head-mounted devices need to incorporate many components, including an optical engine and light source. By integrating the driver function into the micro display, our OP02220 saves board space and streamlines the development process, allowing designers to accelerate the time-to-market and create lighter, more comfortable products for their customers.”
The OP02220 has a pixel resolution of 1920 x 1080 and is built with the company’s 4.5-micron pixel technology, allowing it to have a 0.39-in. diagonal display size. With the integrated driver design, power consumption is significantly lower when compared with two-chip solutions, which extends battery life.
