The World's Smallest 720p High Definition
LCOS Display for Wearable Electronics
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 ultracompact 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.
