摘要
Abstract
Aiming at improving the detecting frequency and sensitivity,mountain-climb searching algorithm was used in projective capacitive touch-screen for the capacitance measuring of the sensor-electrodes. With the control of computer programs and some detecting circuits,the ordinary mountain-climb searching algorithm and the optimized one were realized on a precise projective capacitive touch-screen. The analysis of the program running process indicates that,with the mountain-climb searching algorithm,the detecting frequency of a precise projective capacitive touch-screen can be improved for at less several times compared with the tradition detecting methods. Except this,the optimized mountain-climb searching algorithm can also improved the anti local disturb capability of the touch-screen. Test of sensitivity by line-drawing methods also indicates that the mountain-climb searching algorithm can effectively improve the detecting sensitivity of projective capacitive touchscreen.关键词
