S9255 Product Brief
DVI Interface with TCON Display Processor
C9255-PBR-01B September 2002
DESCRIPTION
The Genesis s9255 is a highly integrated, feature-rich
digital input LCD monitor controller targeted at SXGA
resolution monitors. It inputs DVI-compliant signals and
will perform advanced image processing to ensure the
best display on a TFT LCD Monitor. It features an
advanced scaling architecture with five zone variable
scaling and edge enhancement capabilities in the native
resolution modes. A programmable poly phase filter
ensures smooth natural images and enhanced sharper
text to provide excellent image quality.
A proprietary video window detection algorithm detects
coordinates of any video data overlayed on the image.
The flexible scaling architecture also allows prog-
rammable scaling coefficients in either a defined region
or on the entire screen. A state of the art and industry-
first Adaptive Color and Contrast (ACC) along with the
Auto Backlight Level Control (ABL) ensure excellent
viewing quality for both static and dynamic images.
s9255 has second generation Active Color
Management TM. This technology provides accurate
flesh tone compensation, color space conversion and
hue / saturation control over either a programmable
window or the entire screen. Dual 10 - bit color look up
tables allow independent gamma control for a
programmable window and the background image.
Integration of a state of the art 135 MHz DVI receiver,
industry's best scalar and a host of other advanced
features for video and color control make the s9255 an
excellent solution for DVI monitors.
