Almost any device can be enhanced by the addition of a touch-interactive display panel from  a simple touch screen overlay to a full custom assembly, custom glass and / or bezel. Winstar Display provides TFT LCD touch panel sizes including: 3.5" touch panel (3.5" touch screen), 4.3" touch panel (4.3" touch screen), 5" touch panel (5" touch screen), 5.2" touch panel (5.2" touch screen), 5.7" touch panel (5.7" touch screen), 7 inch touch screen (7" touch panel), 10.1" touch panel (10.1" touch screen). Winstar also provides custom cover glass solution for all sizes of our TFT LCD modules.

The Process

In general there are two classes of touch screen technology. Resistive technology allows single-point touch and is a low-cost solution. Capacitive touch supports multi-finger touch, and a superior optical performance. Capacitive touch is typically seen in higher-end devices, but reducing costs make this technology accessible in a wider range of devices. Projected capacitive touch (PCT) means that the lightest of touches will evoke a response, and allows the addition of a cover lens in glass or plastic for a more mechanically-robust solution.

Our Role

Many of our TFT modules can be supplied with a touch panel option. Touch screen technology is improving all the time so please contact us for the latest information.Winstar offers two options of Capacitive Touch technology: Glass to Glass (G-G) and Glass-Film-Film (GFF). The major differences are detailed below.
