日本松下电器产业公司开发出一种高速液晶显示技术,该技术显示动画不失真,视场较宽,可再现清晰图像.该公司既采用适应高速响应的光学自补偿双折射方式(OCB方式),同时又采用光学模拟方式,研制出了光学补偿薄膜,进而实现了高速响应和宽视场显示.另外,根据液晶动作模拟开发了易排列、且温度范围宽的液晶材料.该技术的特点如下:(1)具有16ms以下的高响应速度为使动画图像不失真,响应时间的上升和下降之和必须在1帧(16.6ms)以内.该液晶显示器的响应特性是,白黑2值间为7ms,中间调为16ms以下,适合于动画图像显示.(2)具有上下120°,左右140°的宽视场该液晶显示具有上下120°,左右140°(对比率10:1以上)的视场范围.没有灰度反弹问题,视场色度变化约为过去扭曲向列(TV)液晶的1/3,实现了多色再现.(3)可用制造TN液晶的工艺制作可用制造TN液晶的相同工艺制作高速响应液晶显示器,且加工工艺不需大的变动.主要性能指标:显示屏的对角尺寸:18cm像元数:462×240亮度:350cd/m~2对比率:200:1以上机场范围:上下120°,左右140°(对比率10:1以上不反弹)响应时间:7ms(室温下)(No.40)
Japan’s Matsushita Electric Industrial Co., Ltd. has developed a high-speed liquid crystal display technology, which shows the animation is not distorted, wide field of view, can reproduce clear images. The company uses both high-speed adaptive optical self-compensating birefringence method (OCB mode) At the same time, an optical compensation film was developed by using optical simulation method to realize high-speed response and wide field of view display.Furthermore, a liquid crystal material with easy arrangement and wide temperature range was developed according to the liquid crystal movement simulation. The characteristics of the technique are as follows: (1) High response speed of less than 16 ms In order to keep the moving picture from being distorted, the sum of the rise and fall times of the response time must be within one frame (16.6 ms). The response characteristic of this LCD is that the black and white 2 values are 7 ms , The middle tone of 16ms or less, suitable for animated image display (2) has a wide field of view 120 ° up and down, left and right 140 ° The liquid crystal display has a vertical and horizontal 120 °, left and right 140 ° (contrast ratio of 10: 1 or more) Range.Without the problem of grayscale bounce, the change of field chromaticity is about 1/3 of that of the past twisted nematic (TV) liquid crystal, so as to realize the multi-color reproduction. (3) The process of manufacturing the TN liquid crystal can be used to make the same Process production of high-speed response Crystal display, and the processing technology without major changes. Main performance indicators: Diagonal size of the display: 18cm Number of pixels: 462 × 240 Brightness: 350cd / m ~ 2 Contrast ratio: 200: 1 and above Airport range: up and down 120 °, left and right 140 ° (contrast rate of 10: 1 or more does not bounce) Response time: 7ms (room temperature) (No. 40)
