Description

Many assume LCDs will quickly dominate the TV market by simply scaling existing LCD monitor panels to wider formats (e.g. 16:9 HDTV) and larger sizes. However, a number of TV requirements push beyond the state-of-the-art monitors of today; response time, brightness, contrast, color envelope, color temperature, and progressive scan-and-hold issues require a reengineering of the monitor solution.

Building upon the strengths of National’s LVDS and RSDS technology solutions in digital video-data communications, we have created a completely new architecture that fully addresses the needs of TV while supporting existing platforms. The Point-to-Point Differential Signaling (PPDS TM) architecture is more than a data link between the timing controller and the column driver. It is an architecture that supports very large displays with features like multiple windows each with its own gamma, various gamma optimizations, color balance at every gray level, minimal bezel size, a 30-bit and beyond color path to the display surface, four-color mosaics and numerous other benefits.
