How To The Touch Screen Works

Structure The following figure is a touch screen. How does the touch screen you can see the structures that make the Touch screen.

 

Touch sensor is an outer layer receiving input from the monitor. Input from the touchscreen is a touch, so it means the sensor is also a touch sensor. Usually in the form of a touch sensor panel surface is made of glass which is very responsive to the touch. Touch sensors are placed on the front surface of a touchscreen display, thus the area that is responsive to a touch cover the viewable area of ​​the monitor screen. Therefore when we touch the surface of the screen, input has also been given by us.

Touch sensor technology that is now widely used consists of three kinds, as described above, the resistive touchscreen, touchscreen Capasitive, and Surface wave touchscreen. All of these sensor types may work together, that is capturing changes in currents and electrical signals that exist on these sensors, record it and turn it into coordinate points above the screen, so the exact position of a touch can be directly known correctly .

Touch screens can be run with a controller component .The controller is a device used to link the sensor with a computer device that will process these sentuhansentuhan. When the sensors record a touch event, the data it has transmitted to a controller. The controller will then be to translate  the information from these sensors into information understandable by a computer processor. Once information is entered and processed by the processor, the end result will be issued again to the monitor for display. Return the controller on duty to translate the information  from the processor  to be converted into  a form of  images  displayed  on the monitor  screen.
