Touch Screen Display
A lcd touch displayis a combination of a TFT LCD displayand a touch technology overlay, It can be used as a display as well as a keyboard, which enables the users to operate without a mouse or touchpad. And because of its convenience and long lifespan compared with traditional buttons, touch screens adapted themselves into every aspect of our daily life quietly.
There are many types of lcd touch screen paneltechnologies available in the market, the main two types are resistive touch panel (RTP) and projected capacitive touch panel (CTP). The resistive touch screen panel works by detecting pressure changes, A projected capacitive touch panel identify the electrical current by using sensors to sense the human body static electrical capacity, which means if you wear normal gloves, the CTP touchscreens won’t respond.
As a tft panel manufacturer, Exson experts can not only provide you with standard touch solutions but also various manufacturing methods, such as resistive touch screen panel, open frame lcd display tftand custom capacitive touch panel. Whatever the needs of your project, we can build a custom solution for you.

Why IPS display is better for optical bonding with CTP?
It breaks the angel limitation and provides full viewing angles,
It's brighter with higher color contrast, also thinner, as the liquid-crystal molecules aligned in parallel with the glass plates, much less sensitive on cell gap change.
