What Are Basic Types Of Touch Screen?

For fundamental understanding, a touch screen device comes with the ability to analyze a touch on the display screen area.

It is essential to mention that a touch screen was developed by integrating three essential elements- a sensor, a controller, and a software driver.

Here’s a detailed breakdown of all the significant touch screens, which are actively used at present.

What is a Resistive Touchscreen?

Resistive Touchscreen is one of the most common touch screen types available in the industry. This particular screen type can be split up into 8-wired models, which effectively sets apart the touch coordinates.

It’s essential to mention that a resistive screen is entirely dependent on a touch overlay while basing on a flexible top layer and rigid bottom layer. Insulating spacer dots further separate this.

It is necessary to mention that a resistive touchscreen can only offer 75% clarity, although being durable and easy to integrate.

What is Capacitive Touchscreen?

Capacitive Touchscreen is heavily used for industrial purposes in modern times. This touch screen type features a glass overlay and a conductive material coating, namely Indium Tin Oxide.

It is essential to mention that any contact with a capacitive screen triggers an electrostatic charge, immediately sending the command to the touch panels for action.

It is necessary to mention that capacitive screen provides good quality clarity and durability. However, they are structured to only respond to actions initiated by simple finger touch or special gloves until the industrial touch panel is capacitively charged.

What is SAW (Surface Acoustic Wave) Touch Screen?

Surface Acoustic Wave Touch Screen or SAW Touchscreen is constructed on two transducers and a reflector strategically placed on the glass surface.

This effectively causes the waves to disperse all over the screen using the reflector arrangement as a bouncing board, a transducers layer. The device detects any touch when those waves are absorbed.

The SAW  screens are capable of offering superior clarity, resolution, and durability. Additionally, the screen comes with the ability to detect gloves.

What is Infrared Touchscreen?

It’s essential to mention that infrared touchscreen technology doesn’t follow suit with the other touch screen types- with no overlay for incorporation. Instead of the overlay, the display has a surrounding frame that features LEDs and phototransistor detectors on both sides. The infrared type is widely used in outdoor locations due to its increased durability.

Other touch screen variants are available in the market, each having its individual and distinctive characteristics and functions for excellent benefits.
