Capacitive Touch Screen In Smartphones
Capacitive touch screens in smartphones have become the most popular choice for the cellphone screen. The reasons for this is an increased responsiveness and potentially higher resolutions that can be achieved over resistive touch screens.
What Does Capacitive Touch Mean?
To answer this more easily, it would be better to understand the technology behind capacitive touch through glass. At ITO Touch, we use an ITO (Indium Tin Oxide) coating in our capacitive touch screen in smartphones production.
ITO is both transparent and electrically conductive, making it ideal for use in capacitive touch screens. The ITO coating is integral to the device being able to register a touch (or command).
As we mentioned, the coating is conductive, meaning electricity can pass through it. Touching the ITO coated screen will draw some of its voltage to your finger. The device will register this change in voltage (the touch, pinch or swipe) as a command.
To answer the question, in short – when the voltage changes, the capacitive touch screen device will identify this change of capacitance as a touch command.
Capacitive Touch Screen In Smartphones
Capacitive touch screens in smartphones will not register your touch commands if you are wearing gloves as the commands are only registered as your skin is semi conductive. Not a huge deal as you can get specialist conductive gloves or conductive pointers.
ITO Touch run their own state of the art coating plant and have perfected the process of manufacturing capacitive touch screens. As we can apply a coating direct, we have become more competitively priced – our competitors mostly apply to film which does need more labour costs and processing stages.
