Controllable Viewing-Angle Display Using GHLC Cell as Backlight Panel

Abstract:

Article Preview

There is a desire for a display technology which can change the display viewing angle. Controllable Viewing Angle (CVA) device has been developed by using a Guest-Host liquid crystal cell which allows a high light-shielding effect and the control with a wide range of available viewing angle. By putting the CVA device on a Thin-Film Transistor ( TFT ) Liquid-Crystal Panel, or placing a Guest-Host Liquid Crystal (GHLC) device between the LED and the backlight, we have realized a simple controllable viewing-angle LCD which could be switched in the narrow and normal(wide) viewing angle. The viewing angle can decrease to 40° when power is on but it also can shift to normal viewing angle when power is off.
