TOUCH SCREEN SYSTEM USING TOUCH PEN AND TOUCH RECOGNITION METOD THEREOF

摘要

Touch-screen system is using stylus and touch control identification method and its openly. Touch-screen system includes the stylus of touch screen panel,For by including panel and optical touch-control module,First and second imaging sensors include the top corner panel of two sides to obtain the one or more sensors of touch recognition image,When the panel touched on touch screen passes through infrared light,It is by the panel including side at the top of panel that light emitting diode array, which emits light into,,Photodiode array is received from light emitting diode array by being placed on surface LED display,The top and bottom that diode portions emit or reception light is placed on panel with light emitting diode array correspond to touches dead zone for identification,In dead zone,The side that the reflection infrared light of return reflector plate is radiated panel extends longitudinally through imaging sensor,And the coordinate information of the first touch point is extracted in master controller,Because triangulation method is carried out to it using incidence angle operative algorithm being applied through touch recognition image and being extracted the coordinate information of the second touch point to pass through light emitting diode array,Photodiode array,With diode part,Compare the first coordinate information to the second coordinate information,To identify touch point or pipe dream according to comparison result. ;The 2014 of copyright KIPO submissions
