等离子体显示是稳定的平板显示,然而如同 CRT 技术的其它对手那样,在 CRT 显示的严重挑战面前,等离子体显示必须具备多色性能。要想达到多色显示的优质明暗度必须具备多级灰度。法国 Thomson Tubes E lectroniques 公司(位于法国布洛涅一比扬古)研制的 TH7627型单色 AC 等离子体显示板(PDP),195×260mm 屏幕具有4级灰度。显示象素为640×480,点距0.41mm。该板亮度为150新烛光/米~2。该公司计划生产具有600新烛光/米~2的阳光下易读的高亮度型号。此外,该公司正在研制8种色彩的17英寸 AC PDP,1990年拿到样机,1991年开始生产。
Plasma display is a stable flat panel display, however, as is the case with other competitors in CRT technology, plasma displays must have multicolor performance in the face of the serious challenges presented by CRTs. To achieve high-quality multi-color display brightness must have a multi-level gray. The TH7627 Monochrome AC plasma display panel (PDP), developed by Thomson Tubes E lectroniques, Inc. of Boulogne-sur-Mer, France, has a 4-level gray scale on a 195 × 260mm screen. The display pixel is 640 × 480, dot pitch 0.41mm. The board brightness of 150 new candle / m ~ 2. The company plans to produce high-brightness, easy-to-read models with 600 new candle / meter-2 sunlight. In addition, the company is developing an 8-color 17-inch AC PDP that was prototyped in 1990 and started production in 1991.
