美国摩托罗拉实验室 (Motorola Labs)日前宣布，已开发出一种可提高反射式液晶显示器图像质量的新技术，称为 Electrically Tunable Color(ETC)。 ETC通过加至液晶盒上的平行 (in plane)电场，控制胆甾相 (cholesteric)液晶螺旋状结构的螺距来改变其反射光的颜色。这种技
Motorola Labs announced that it has developed a new technology that enhances the image quality of reflective liquid crystal displays, called Electrically Tunable Color (ETC). The ETC controls the pitch of the cholesteric liquid crystal spiral structure by changing the in-plane electric field applied to the liquid crystal cell to change the color of the reflected light. This technique
