Abstract :
An calibration algorithm of the touch-screen is researched which exploring an eliminating noise method after the analysis of linear principle. The block diagram of the touch-screen system is introduced, and the calibration program is designed based on the four-point linear calibration algorithm in this paper. An embedded system with touch-screen software is designed with the development tool ADS. The stability and precision of touch screen system with the improvement of algorithm calibration is proved by the testing and valid dating of the algorithm in practical system.
