Blog: Gvision-USA.com HOW DOES A TOUCH SCREEN DETECT INPUT? Touch screen display is an equipment which looks like an invisible keyboard stick to the screen of your monitor, and helps to interact user directly with the system by touching the screen. A Touch display has taken on a vital role in every aspect of our busy and competitive life. We enjoy operating digital devices like smart phones and interact with touch screens throughout the day. It simplifies the efficiency of a device by combining display and input into a single platform of the equipment. But to understand how it actually works, you should know about some main technologies, which have different types and work in different ways. Resistive Resistive touch display is configured with a strong resistance to outside elements like dust or water. It is more affordable and has a low manufacturing cost, but offers average clarity and can be damaged by sharp objects, as it consist of two thin and flexible layers. Surface waves Surface waves touch was developed to overcome the drawbacks of low light transmittance in touch panels. It offers ease of operating. When the screen is touched by the user, panels detect the screen, ultrasonic waves register position of touch event and transfer it to controller for processing. Normally, a user does not sense the vibrations when touching the screen. Capacitive Capacitive touch screen panel is basically developed for small screens to achieve high-precision multi touch function and speedy response. When the screen is touched, circuits of each corner measure the charge first and then transfer the information generated. It enables exact recognition of contact at multi touch pointswith the help of large number of electrodes. These are the three main formats in which touchscreen monitors detect input.
