Description
Technical field
The present invention relates to a kind of handset touch panel, refer more particularly to a kind of handset touch panel with multi-point recognition function.
Background technology
In at present common on the market touch-screen mobile phone, become the standard configuration of mobile phone and operating personnel's human-computer interaction interface by the touch-screen input.People can come into contacts with as input interface and mobile phone by touch-screen, are implemented in intuitive visualization interface operation on the mobile phone.But, present common on the market touch-screen mobile phone, it only possesses discerns the single contact position on the touch-screen, can not discern mode of operation and the motion conditions of two or more contacts on touch-screen simultaneously, therefore it can only discern some simple single contact or actions, for example press, decontrol and grow by action recognition, thereby limited the identification quantity of touch-screen to the contact action.And the handset touch panel with multi-point recognition function can be discerned multifinger position and moving situation on the touch-screen.Enterprising row distance stretches for example same time two fingers in the position of touch-screen simultaneously, or the athletic performance of reduction.Handset touch panel with multi-point recognition function can amplify picture realization picture selected on the mobile phone or dwindle.When refer to be the center with one on handset touch panel, when another referred to make an arc line on touch-screen, this handset touch panel with multi-point recognition function can be realized the picture spinfunction to picture selected on the mobile phone.
Summary of the invention
The technical problem to be solved in the present invention is: overcome existing handset touch panel and only can discern some the simple single contacts of carrying out or the shortcoming of action recognition on touch-screen, a kind of handset touch panel with multi-point recognition function that can discern multifinger position and moving situation on the touch-screen simultaneously is provided.
In order to solve the problems of the technologies described above, the present invention proposes following technical scheme: a kind of handset touch panel with multi-point recognition function, it comprises a touch-screen module Touchpad Module, a host computer communication Host.This touch-screen module Touchpad Module mainly is made up of touch screen induction device Touchpad Sensor and touch screen controller Touchpad Controller.Electrically connect between this touch screen induction device Touchpad Sensor and the touch screen controller Touchpad Controller.Between this touch screen controller TouchpadController and the host computer communication Host by DVDD, SDI_RX on this touch screen controller Touchpad Controller, SDO_TX, INT, SCK, SS, DGND pin respectively with host computer communication Host on VDD, UART_TX, UART_RX, GPIO, GND pin electrically connect.
Originally the basic functional principle of handset touch panel that has multi-point recognition function is as follows: when finger contact touch-screen, touch screen induction device Touchpad Sensor promptly can pass to touch screen controller Touchpad Controller to the induction field electric weight and handle, touch screen controller Touchpad Controller converts this analogue value to two-dimensional coordinate numerical value, send to upward UART_TX end of host computer communication Host by the SDO_TX pin on this touch screen controller Touchpad Controller after being packaged into Serial No., Serial No. is sent on the host computer communication Host.Because host computer communication Host can receive the coordinate data information that comprises two positions point, when pointing actions such as on touch-screen, doing stretching, gathering, host computer communication Host according to real-time coordinate information promptly can be regarded as 2 distance between two fingers on the touch-screen, image processing module is determined the picture amplification coefficient according to this distance, amplifies or calculation process such as dwindles thereby make picture.When finger is made an arc the line action on touch-screen, host side according to real-time coordinate information promptly calculate the angle of line segment between 2 between two fingers on the touch-screen, the image processing module that is installed on the host computer communication Host can be determined the picture coefficient of rotary according to this angle, thereby makes the calculation process of picture rotation.Last host computer communication Host is apparent in the calculation process result on the handset touch panel, can manifest on this touch-screen image amplification, dwindle, effect such as rotation.
