Abstract

The invention discloses a method and a system for using a plurality of resistive touch screens to realize multi-point input, wherein the method is used for a mobile phone provided with at least two blocks of resistive touch screens and includes the following steps of detecting each block of resistive touch screen on the mobile phone; and when detecting that any touch screen is touched, then obtaining the contact coordinate information of the touched touch screen. The system includes: a plurality of blocks of resistive touch screens, a control unit and a driving circuit unit. A plurality of the resistive touch screens are mutually connected in parallel and accessed to the driving circuit unit; the driving circuit unit is connected with the control unit and used for converting a voltage signal generated when the touch screens are touched to the coordinate information of the contact and transmitting the information to the control unit; and the control unit is used for receiving the coordinate information of the contact. Compared with the prior art, the invention can use the low-cost resistive touch screens to realize the input of multi-point touch and combination action, cause user operation to be simpler and more convenient and improve use convenience.

Description

technical field [0001] The invention relates to the field of electronic circuits and their applications, in particular to a method and system for realizing multi-point input by using multiple resistive touch screens. Background technique [0002] As a convenient input device, the touch screen is used more and more widely, and it has almost become a standard configuration on handheld terminals. The types of touch screen implementation technologies are divided into: resistive, capacitive, infrared, surface acoustic wave, electromagnetic, near-field imaging, etc. Resistive touch screens are currently the most widely used and lowest cost touch screens. [0003] The physical structure of the existing four-wire resistive touch screen is as follows: Figure 1A shown. As shown in 103 , the touch screen is composed of three overlapping layers: a layer of X-direction resistor 101 , a layer of Y-direction resistor 102 , and an isolation layer between the two layers of resistors. The...
