Differences between Resistive and Capacitive Touch Screen

The touch screen is not just limited to use on Smartphone and tablet, but already are applied everywhere, such as at ATM machines, navigation systems, gaming consoles and even the touchpad / laptop. The touch screen now appears everywhere and takes an important role in our lives.

We will find out how the touch screen technology works on the phone or tablet.

Handphone touch screen is divided into two types, namely resistive and capacitive. Both types of these handphone touch screen can be found on some Smartphone and tablets. With this technology the menu list are on the phone or tablet will respond quickly even if only by a small touch. However, there are some devices, which although be touched with a small touch, they do not work, but it should be with a harsh touch.

You may ever feel the difference. When that happens, you may be wondering, why your iPhone does not work when you are wearing gloves? Why the touch screen on a feature phone is different with high-end phone? Why you cannot use the entire stylus pen on your iPad?

All of these questions can be answered only with two answers, namely resistive and capacitive. Differences of the resistive and capacitive touch screen will be described with the explanation below.

Resistive Touch Screen
Touch screen that has a resistive type is most common. As the name, resistive touch screen to rely resistant style (resistive itself is taken from the name of the resistance). From this sense can be known that the working of the resistive touch screen is based on the style of resistant or pressure.

Resistive touch screen takes a bit of pressure to process touch and not always respond quickly like iPhone. In addition, several layers of resistive screen may result in the screen becoming less sharp with lower contrast than that seen on the capacitive screen. Meanwhile, most of the least resistive screen allows performing multi-touch gestures such as pinch to zoom.

Resistive screen has renewed system for many years, and today many mobile phones on the low-end class also apply the resistive touch screen to their cell phone, but still less accurate with mobile phones with high-end class.

Capacitive Touch Screen
Capacitive touch screen found earlier than the resistive touch screen. However, capacitive touch screen is now more accurate and respond instantly when in contact with human fingers.

How the workings of a capacitive touch screen?

Unlike the resistive touch screen that relies on mechanical stresses that created by a finger or stylus, capacitive screen is actually using the electrical properties of human. Capacitive screens are usually made of a single layer of insulation, such as glass that coated with a transparent conductive material in it. Because the human body is conductive, which means electricity can pass through the human body, the capacitive screen can use this conductivity as input. When you touch capacitive screen with your finger, it will lead to changes in the electric field on the screen.

Capacitive layer can receive and forward electric current from your fingers are then directed to the sensor. This allows you to use your fingers to operate it.
