What is a touch screen?
A touch screen allows user commands to be issued by pressing corresponding buttons on the screen. Since their introduction in the 1970s, touch screens have become popular for computer and media technology. Chances are, if you have used an automated teller machine (ATM), owned a personal digital assistant (PDA), or played with the newer cell phones, you have already used touch screen technology. There are several commonly used systems that allow for touch screens to work. Each method allows for commands to be translated by the computer as a result of touching a certain point on the screen. Many convert the coordinates of the touch locations to specific actions to be taken by the system. One of the most common systems for touch screens is called resistive. Covering the transparent panel of the screen are conductive and resistive metallic layers that have an electric current between them. When the screen is touched, the electrical current can tell the exact spot of contact and send the co
A touch screen is a transparent device integrated into the monitor (or terminal) that allows the operator to interface with the computer by simply touching the image displayed on the screen. When the operator touches the screen a signal is generated that identifies the location of the touch relative to the screen image. This information can then be interpreted and acted on. Touch screen applications are very common on flat panel LCD monitors. StarPanel’s standard touch screens use resistive touch overlays. Resistive touch technology is cost effective, rugged, and offers touch resolution down to the individual pixel.
