开发彩色液晶显示器的美国俄勒冈州 In Focus 系统公司使用一种新的寻址无源矩阵LCD 象素的方法获得个视频速度,而且未损害显示亮度和对比度。用新方法驱动显示器的样机,响应时间达到50ms,对比度达30:1。该公司开发的这种驱动方法称作能动寻址(ac-tive addressing)。它使用复杂的获得专利的方法获得视频速度,即在帧周期内灵活地分配许多小脉冲,而不是用标准多路驱动 LCD 法的单个大的行选择脉冲。其结果是这种高成品率、
In Focus Systems, Oregon, USA, which develops color LCD displays, used a new approach to addressing passive matrix LCD pixels to achieve video speeds without compromising display brightness and contrast. The new method of driving the display prototype, the response time of 50ms, contrast ratio of 30: 1. The drive developed by the company is called ac-tive addressing. Instead of using a single large row select pulse with a standard multiplexed LCD method, it uses a patented approach to get the video speed with the flexibility to allocate many small pulses over the frame period. The result is this high yield,
