Abstract
Pointing to the deviation of touch screen in actual application, a kind of five-point calibration algorithm was presented. We designed a system with high-performance MCU as the control unit. The data, after AD converted by ADS7845, are calibrated and transmitted to the LCD display. The five-point calibration algorithm system has been used in Ethane Producer Department, Guangzhou Petrifaction Ltd, which realizes calibration error of touch screen.
