MICROCHIP
C2126-PBR-01A
Analog-Interface OnPanel SXGA LCD Controller with RSDS Transmitter
•
RealColor Technology
The gm2126 device is an all-in-one image processor targeted for
the OnPanel LCD monitor market with resolutions up to SXGA.
The gm2126 leverages Genesis patented advanced image-
processing technology and a proven integrated ADC/PLL to
provide excellent image quality in a simple and cost-effective
solution. The integrated OnPanel timing controller (TCON) is
•
•
Digital brightness and contrast controls
TV color controls including hue and saturation
controls
Flesh-tone adjustment
Full color matrix allows end-users to experience
the same colors as viewed on CRTs and other
displays (e.g. sRGB compliance)
•
•
fully programmable to interface with
a wide range of
commercially available LCD panels. A dual channel RSDS
(reduced swing differential signaling) 6 or 8 bit transmitter is
provided for direct connection to column drivers with RSDS
inputs. This high level of integration reduces the number of
components, which eliminates a PCB along with its associated
connectors and cables. This reduces system cost, improves
reliability and simplifies monitor design.
