High-definition LCD controller tackles harsh environments

By Warren Webb, Technical Editor -- EDN, 3/6/2008

Targeting manufacturers developing rugged panel-display systems with high resolution and high definition, Digital View recently introduced the HE-1920 COTS (commercial-off-the-shelf) LCD controller. The fully buffered, multisynchronous interface controller provides analog and digital connections for a wide range of TFT (thin-film-transistor) LCD panels with resolutions as great as 1920×1200 pixels. It features full-screen image expansion of lower resolutions, image-flip and -invert functions, and onscreen picture-in-picture functions.

The HE-1920 also features a 16-bit bus connector that permits developers to independently create proprietary hardware interfaces for the controller. The interfaces provide software-managed selection pins to manage multiple input configurations, including optical inputs and additional ports. The HE-1920 targets use in the harsh environments of military and rugged industrial applications. It features silicon-resin conformal coatings, an operating-temperature range of –40 to +80°C, and calculated MTBF greater than 100,000 hours, and full compliance with ROHS (restriction-of-hazardous-substances) directives. The HE-1920 sells for $269 (1000).
