NEC Japan has announced a prototype wide-screen LCD panel with enough resolution for use in high-definition television applications.

The TFT (thin film transistor) LCD (liquid crystal display) panel has a wide-screen 16:10 aspect ratio and a diagonal size of 20.1 inches, NEC said. In addition to high-definition TV applications, the new panel could also be used in 3D computer-aided design and desktop publishing, or as a multimedia display, the company said.

The screen's 2.3 million pixels offer a maximum resolution of 1,920-x-1,200 pixels. It‘s compatible with conventional 8-bit RGB signals and supports up to 16.77 million colours. It has a brightness of 400 cd/m2 (candelas per square meter), and a contrast ratio of 280:1.

Compared to high-end NEC flat panel computer monitors available now, the new display offers around double the brightness and contrast while featuring pixels around 20 per cent smaller in size, according to NEC.
