720p HD LCOS Chip Set Solution
for Compact Projection Systems
The OVP7200/OVP921liquid crystal on silicon (LCOS)
chip set brings high definition (HD) image resolution to
very small projection systems. The OVP7200 panel has a
resolution of 1280 x 720 pixels and a diagonal
measurement of 0.37-inch, making it ideal for low cost
HD projection systems. The companion driver ASIC, the
OVP921, integrates a host of features that simplify
system design, while saving both space and power.
The OVP7200 is a single panel, color field sequential
device, based on a 6.4-micron pixel in an array with a
native resolution of 1280 x 720 pixels. The OVP7200
uses all-digital technology to drive the liquid crystal,
resulting in stable, reproducible image quality.
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, LED controller, and an
embedded 8051 microcontroller (MCU). Additionally, the
OVP921 can accept inputs via 24-bit RGB, MIPI or USB.
The OVP7200 is large enough to couple well with LED
light sources, yet is small enough to meet the demands of
compact projection systems for mobile and automotive
applications. The HD resolution of OVP7200/OVP921
combined with solid state light sources allows customers
to create low-cost, compact projection systems with high
optical output.
