Product Brief gm3115
C3115-PBR-01B
Digital-Interface OnPanel XGA LCD Controller
The gm3115 device is an all-in-one image processor targeted on
the “Smart” LCD panel market with resolutions up to XGA
(1024x768). The gm3115 leverages Genesis patented advanced
image-processing technology as well as a Genesis patented
Ultra-Reliable DVI-compliant digital receiver to provide excellent
image quality in simple and cost-effective solutions. The
integrated OnPanel timing controller (TCON) is fully
programmable to interface to a wide range of commercially
available LCD panels. In addition, an integrated microcontroller
is provided. This high level of integration reduces the number of
components by eliminating the need for an LCD controller PCB
and its associated connectors and cables. This reduces system
cost, improves reliability and simplifies monitor design.
