A NON-TOUCHING TOUCH SCREEN AND A METHOD FOR IMPLEMENTING A MOBILE COMMUNICATION TERMINAL USING THE SCREEN

摘要

A non-touching touch screen and a method for implementing a mobile communication terminal using the screen are disclosed. The non-touching touch screen includes: a glass base layer (1), a conducting layer (2), the isolating dots (3) and a photoelectric sensing layer (4). The glass base layer (1) is a transparent supporting layer, the conducting layer (2) is plated on the surface of the transparent base layer (1), and the conducting layer (2) can obtain a voltage of 0-5 volts from the power supply system. Many tiny isolating dots (3) are set on the surface of the conducting layer (2) regularly, and they are covered by the photoelectric sensing layer (4). When the screen is irradiated by the laser beam (6), the photoelectric sensing layer (4) on the screen is broken down and becomes a short circuit with the underlayer conducting layer (2), and the supporting processing software can measure and calculate the position of the dot broken down, and transmit the position to the micro-processor for the purpose of that the micro-processor processes other judgments and takes the corresponding event action. This mode changes the existing touching mode operating, and supplies the defects on the interactivity, and solves the problem that the abrasion of the mobile communication terminal with a touch screen is fast and the life cycle of it is short.
