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.
