Abstract

A bright reflective LCD without a backlight is a key device for portable information systems. The guest-host LCDs use the absorption anisotropy effect of dichroic dyes and have a wide viewing angle cone. The GH-LCD does not need complicated designs of optical compensation in birefringence or optical rotatory power modes. One of the applications of GH-LCDs is a black and white display which works as a light shutter of a full color reflective display with micro-color filters. It is necessary to mix dyes for an achromatic display. The Newton-Raphson method is useful for the calculation of optimum dye concentrations in order to display the designed color. In this work, the judgement of the calculated results is discussed. As a result, the calculated result with Newton-Raphson method is quickly and easily evaluated. The process gives us a helpful guideline in the fabrication of the reflective color LCDs and it is expected that the precise color matching improves the quality of LCDs.
主动式液晶显示器的比色特性
无背光的明亮反射LCD是便携式信息系统的关键器件。主客液晶显示器利用二向色性染料的吸收各向异性效应,具有宽视角锥。在双折射或光旋转功率模式下,高功率液晶显示器不需要复杂的光补偿设计。gh - lcd的应用之一是作为带有微彩色滤光片的全彩反射显示器的光快门的黑白显示。要使显示无色差,必须混合染料。牛顿-拉夫逊法用于计算最佳染料浓度,以显示所设计的颜色。本文讨论了计算结果的判断问题。因此,牛顿-拉夫逊法的计算结果可以快速、方便地进行评价。该工艺为反射彩色液晶的制作提供了有益的指导,并期望精确的颜色匹配能够提高液晶的质量。
