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 WF70GTZAGDNT0 is a 7 inch O-Film TFT-LCD display with RTP on module. This TFT module can be operating at temperatures from -20℃ to +70℃; its storage temperatures range from -30℃ to +80℃.
