Capacitive vs Resisitive Touch Screen

What is Resistive Touch? Why Resistive Touchscreens?

Resistive touchscreens use pressure as input. Made up of several layers of flexible plastic and glass, the front layer is scratch resistant plastic and the second layer is (usually) glass. These are both coated with conductive material. When someone applies pressure to the panel, the resistance is measured between the two layers highlighting where the point of contact is on the screen.


Some of the benefits of resistive touch panels include the minimal production cost, flexibility when it comes to touch (gloves and styluses can be used) and its durability – strong resistance to water and dust.


What is Capacitive Touch? Why Capacitive Touch Screens?

In contrast to resistive touchscreens, capacitive touchscreens use the electrical properties of the human body as input. When touched with a finger, a small electrical charge is drawn to the point of contact, which allows the display to detect where it has received an input.  The result is a display that can detect lighter touches and with greater accuracy than with a resistive touchscren.


If you want increased screen contrast and clarity, capacitive touch screens are the preferred option over resistive screens, which have more reflections due to their number of layers. Capacitive screens are also far more sensitive and can work with multi-point inputs (gloves and styluses can be used), known as ‘multi-touch’.  


which is better?

Although capacitive touchscreen technology was invented long before resistive touchscreens, capacitive technology has seen more rapid evolution in recent years. Thanks to consumer electronics, particularly mobile technology, capacitive touchscreens are swiftly improving in both performance and cost.


At GreenTouch, we find ourselves recommending capacitive touchscreens more regularly than resitive ones. Our customers almost always find capacitive touchscreens more pleasant to work with and appreciate the vibrancy of image that cap touch TFTs can produce. With constant advancements in capacitive sensors, including new fine-tuned sensors that work with heavy duty gloves, if we had to pick just one, it would be the capacitive touchscreen.
