许多致力于制造大面积彩色LCD平板和等离子平板显示器的公司现在开始提供样品。华盛顿Camas的Sharp Electronics公司在1月份举行的消费电子展览会和显示器成果会议上都展示了一种40英寸对角线的彩色LCD。该LCD在4∶3格式中提供了扩展型图形适配器(XGA)分辨率。该公司估计1997年底这种LCD可开始小批量上市。该平板显示器实际上是两块20英寸平板通过光学耦合而形成一个显示区域,分辨率为800×600个像素。它可以显示1670万种颜色,亮度约为200cd/m~2,对比度达150∶1,这要归功于该公司专有的改进型背光源。该平板显示器的工作功耗约130W,背光源消耗其中的大部分功率。为了保证稳定的高质量图像,该LCD与主机系统之间利用低压的差动信号进行通信,从而减少了可能出现的电磁干扰。 在此次的显示器成果会议上还展出了3种等离子平板显示器:纽约州Highland的Matsushita Electric Indus-trial公司Plasmaco子公司展示了42英 Many companies dedicated to making large-area color LCD and plasma flat panel displays are now sampling. Sharp Electronics Inc. of Camas, Washington, is showing a 40-inch diagonal color LCD at the Consumer Electronics Show and Display Achievement Conference in January. The LCD provides Extended Graphics Adapter (XGA) resolution in the 4: 3 format. The company estimates that by the end of 1997 the LCD will be available in smaller quantities. The flat panel display is actually two 20-inch flat-panel optically coupled to form a display area with a resolution of 800 × 600 pixels. It displays 16.7 million colors with a brightness of about 200 cd / m 2 and a contrast ratio of 150: 1, thanks to the company’s proprietary retrofit backlight. The flat panel display operating power of about 130W, the backlight consumes most of the power. In order to ensure a stable and high quality image, the LCD and the host system use low-voltage differential signals to communicate, thus reducing the possible electromagnetic interference. Three plasma flat panel displays were also featured at the Monitor Achievement Conference: Plasmaco’s subsidiary of Matsushita Electric Industrial-trial, Highland, NY, presented 42-inch
