Non-contact type touch screen and method for realizing mobile communication terminal by same

Abstract

The invention discloses a noncontact touch screen and a method for implementing mobile communication terminal using this screen. And the screen comprises: glass substrate, conducting layer, isolating points and photoelectric inductive layer, where the glass substrate is a transparent support layer, the conducting layer is coated on the glass substrate, and able to obtain 0-5V voltage by power supply system, the isolating points with very small granularity are regularly arranged on the conducting layer, and the photoelectric inductive layer is arranged on these isolating points. When a laser irradiates the screen, the photoelectric inductive layer on the screen is broken down to be short-circuited with the conducting layer, and here, a supporting processing software can calculate position of the current breakdown point according to the breakdown place and transmits the position to a microprocessor to make other judgments and corresponding event actions. And it changes the existing touch mode operation, makes up for interactive defect and solves the problems that mobile communication terminals with touch screens have large losses and short life.

Description

technical field [0001] The invention relates to a method for realizing the operation of a mobile communication terminal in the field of mobile communication, in particular to a non-contact touch screen and a method for realizing a mobile communication terminal using the screen. Background technique [0002] At present, the rapid development of the entire communication industry has led to the rapid development of a series of industries, and mobile terminal products have also been rapidly updated, from the small monochrome display at the beginning to a slightly larger monochrome display or a certain The monochrome display screen of the color scale, followed by the development of technology, the intensity of competition has increased. In order to find differentiation and individuality and improve the profitability of products, 256-color display screens have begun to be used on mobile terminals, so a Out of control, 4096-color, 65535-color and even 260,000-color color displays h...
