OmniVision Technologies, a leading developer of advanced digital imaging solutions, has announced OmniGlass, a new reference design that combines a 720p LCOS [liquid crystal on silicon] wearable display and a 4MP camera module for the rapidly growing wearable electronics market. The device is also equipped with OVP921, a companion chip that provides image processing support. Actual manufacturers may buy components and license design and then release OmniGlass commercially.
The OmniGlass reference design is a complete optical head-mounted display (OHMD), equipped with a 4MP autofocus camera that delivers high quality 720p HD video, and a best-in-class display enabled by OmniVision’s high-performance OVP2200 LCOS solution. The single-chip OVP2200 is a color field sequential LCOS device with a native resolution of 1280*720 pixels and a diagonal measurement of 0.26”. It uses all-digital technology to produce clear, stable images. The OVP2200’s ultra-compact form factor and low-power consumption make it an ideal LCOS solution for applications ranging from wearable smartphone displays to sports and medical cameras.
The OVP921 companion chip provides enhanced system performance without the need for external memory or an image processor. It has built-in keystone correction, frame rate conversion, video input scaling, interface to LED controller and an embedded microcontroller. The OVP921 can accept video data from three different signal inputs: 24-bit RGB, MIPI or USB. The device’s image processor is capable of supporting various wireless connections, including Wi-Fi and Bluetooth, and enables on-screen display (OSD) features for augmented reality applications.
“We are bringing the OVP2200 to market at a time when the wearable electronics industry is poised for explosive growth. Industry analysts are predicting that the global market volumes for wearable electronics will exceed 130 million units by 2018, reaching an estimated $8 billion in revenues. By building the OVP2200 LCOS display into the OmniGlass reference design, we can help enable our customers and partners to quickly enter the burgeoning wearable display and camera markets with highly competitive offerings,” said Raymond Sun, senior manager, LCOS business at OmniVision
A prototype of OmniGlass is currently available for demonstrations, and a development kit is available for customer sampling upon request. The OVP2200 is currently sampling, with volume production expected to begin during the second quarter of 2014.
