DESCRIPTION
Winstar Display offers a series of medium size O-Film TFT (Thin Film Transistor) displays featuring with wider viewing angle Technology. Most industrial application of TFT-LCD glasses that are available in the market are TN-LCD type. However, TN technology suffers from phenomenon called gray scale inversion. This means the display have one viewing side in which color of the image change suddenly after exceeding specified view angle. Therefore, the normal TFT models we offer which the viewing angle are limited. Winstar offers an O-Film TFT solution to enhance TN glass viewing angle and can overcome gray scale inversion.
