Technology is constantly evolving, giving people something new to experience from time to time. Consider the touch screen technology that has replaced the buttons and keys system, and now has many wide ranging applications. We can now see touch screen technology being incorporated in cell phones, computers, ATMs, cash tills and several gadgets. Touch screens are efficient, user friendly and attractive as well. Visit your local touch screen rentals service and you will find several equipment and gadgets boasting of a sleek touch screen.

Resistive touch screen

This screen consists of a conductive and a metallic layer separated by spacers. A scratch resistant glass layer is placed over the entire set-up. When pressure is applied on the surface of the screen using a stylus or a finger, the two layers touch and an electric current passes through them. The system’s controller registers the touch and determines the area on the screen at which the contact has been made.

Touch screens of this kind are inexpensive as well as water and dust proof. They have a working life of approximately 35 million clicks. While a stylus or a finger can be used to make contact on the screen, sharp objects would damage the screen. Resistive touch screens let out only 85% of light, don’t recognize multiple touches and are prone to scratches that eventually affect the screens’ sensitivity. This touch screen is widely used in cell phones. Determine the type of touch screen you need before you go for touch screen rentals. For instance, 5-Wire resistive touch screens are ideal for restaurant systems and industrial controls while 4-Wire resistive touch screens are suitable for less demanding environments

Capacitive touch screen

It has just one layer that is completely coated with an electro-conductive material constantly passing a current of a specific frequency. When the screen is touched, the frequency changes and locates the point of touch. This touch screen is moisture and scratch proof. It is more expensive compared to the resistive touch screen. A capacitive touch screen is of two varieties: one that detects a single touch and the other that detects simultaneous multiple touches. It is calculated to have a life span of 225 clicks and lets out about 92% of light. Such screens/displays are widely used in kiosks and industrial controls.

Infrared touch screen

There are two types of infra red touch screens: optical and heat sensitive. An optical touch screen has infrared beams that are invisible to the naked eye. These beams cover the layer of the screen with the help of sensors located around the screen. A gentle touch disrupts the rays and the area of touch is determined. Infrared touch screen is the costliest of all and the most durable as well. It lasts for about seven years. The major drawback of an infrared touch screen is that it can get damaged when exposed to a powerful source of light. Such screens are most commonly used in point-of-sale systems.

It is useful to understand how different types of touch screens work and their applications before investing in a purchase. Touch screen rentals are also a great idea to try out various types before you invest in one.
