Over the years, LCD touch screen technology has evolved and changed. Originally hampered by limitations in screen resolution and slow
response rate, LCD touch screens have made huge technological strides to gain momentum as the touch device
of choice for many input-intensive computer applications. This site will
explain the features of one of the latest of such technologies, resistive touchscreens.
Most of today's touch screen systems are composed of a sensor unit attached to the main display unit, the monitor. This sensor unit uses a hardware controller and software device driver to sense a user's touch. The location, or coordinates, of the touch input is then determined and relayed to the computer's operating system. For resistive touch screen flatpanels, these sensors are connected between the monitor and the serial or USB port of the user's computer.
Resistive touch screen technology possesses many attributes that make it more advantageous than other touch screen technologies. As a result, it is ideal for many touch screen applications, such as desktop, rackmount, and open-frame.
