OmniVision's new ultra-compact and low-power OVP2200 liquid crystal on silicon (LCOS) solution delivers best-in-class 720p high-definition (HD) video at 60 frames per second (fps) to displays in next-generation wearable electronics. The single-chip OVP2200 is supported by the OVP921 companion chip, which provides image processing and further simplifies system design.
The OVP2200 is a single panel, color field sequential device based on a 4.5-micron pixel with a native resolution of 1280 x 720 pixels and a diagonal measurement of 0.26-inch. 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 provides enhanced system performance without the need for an external image processor. The OVP921 has built-in keystone correction, frame rate conversion, video input scaling, an LED controller, and an embedded 8051 microcontroller (MCU). Additionally, the OVP921 can accept inputs via 24-bit RGB, MIPI or USB.
The HD resolution enabled by the OVP2200 and the OVP921, combined with solid-state light sources, allows customers to create low-cost, compact projection systems with high optical output. These systems are capable of projecting images and video at more than 20 Lumens with LED power at 1.8W with a well-designed optical engine.
