DESCRIPTION

If your applications require a wider viewing angle, Winstar O Film TFT technology will be what you need. There are many wider view angle technology for TFT displays in the market such as MVA (Multi-domain Vertical Alignment) and IPS (In-Plane Switching). Comparing to the MVA or IPS technology, O Film TFT has the advantage of pricing. More importantly, the specifications and dimensions of MVA and IPS TFT in the market now are more suitable for consumer products (like tablets and smartphones) not for industrial products.

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. Currently, we offer a solution to enhance TN glass viewing angle and can overcome gray scale inversion. This is our TFT O-Film solution.

The modle of WF43HTZAEDNGB is a standard 4.3 inch O Film TFT LCD Capacitive Touchscreen Display which with a wide view angle solution. Winstar offers a wider view angle solution for our TFT product line. We add an O Film on top of the TFT TN-LCD glass to enhance the viewing angle. This will be a cost effectiveness solution in the industrial application for color TFT displays to enhance the view angle.
