Overview
Noritake offers a variety of TFT modules that can meet your application needs.
Command Controlled Type
Compared with existing ITO-based touch panels, our touch technology achieves superior sensitivity.
This includes its ability to operate with a cover glass and gloves even water spillage conditions.
Wide Operating Temperature model available.
HDMI & Touch via USB
SBC/PC ready. This is suitable as an embedded touch monitor for PCs or single-board computers (SBC) that have digital video output (HDMI Type A connector). GT-VP supports EDID and touch via USB is HID compliant, so plug-and-play is possible.
Wide Operating Temperature model available
TFTs and touch panels have an operating temperature range within which the device can continue to function properly. If the device is used outside the recommended temperature range, various problems may occur. For example, the LCD display speed may slow down, the screen may become dark, or the device may not respond to touch. We supply TFT touch panels that work in a wide temperature range.

How it’s Possible
Compared to existing ITO touch panels, Noritake FLETAS® Metallized Projective Capacitive Touch technology possesses superior sensitivity. This includes its ability to operate with thicker cover glass and gloves.
** ITO = Indium Tin Oxide
Dry Condition Comparison
Noritake’s FLETAS® Touch Panel has a greater signal-to-noise ratio than that of ordinary touch panels. As seen in the animation below, the touch signal does not get anywhere close to the surrounding noise on Noritake touch panels. Ordinary touch panels have a lower signal strength and surrounding noise sometimes comes very close to the same height as the touch signal. This can result in a false touch.
Wet Condition Comparison
Noritake’s FLETAS® Touch Panel has a greater signal-to-noise ratio than that of ordinary touch panels. As seen in the animation below, noise reduction also helps Noritake touch panels perform in a wet environment. Minimal noise promotes a very stable and easy to detect peak point.

GT Series Troubleshooting
This guide shows solutions to frequently asked questions and common problems that users may encounter while using Noritake GT series modules.
Cover Glass
The touch panel on the front of this product uses an ultra-thin glass sheet. Do not apply excessive force to the touch panel directly. It is designed to be used behind a protective and transparent front panel or cover glass.
Additionally, an air gap between the touch and front panels should be designed in to allow for deflection.

What are the different types of touchscreens and how are they used?
Touchscreens are input devices such as touchpads positioned over the TFT panels that allow user input and functional display. There are various types of touchscreen technologies available nowadays, and we described what those differences are and how they are used, in the web article.
