发明名称 IN-CELL CAPACITIVE TOUCH SCREEN AND TOUCH CONTACT DETECTING METHOD AND SYSTEM THEREOF
摘要 A method and system for detecting at ouch contact on an in-cell capacitive touch screen includes, based on the different gray scale pictures displayed by the in-cell capacitive touch screen in a non-touch state as well as a distribution of the intersections of rows and columns of the in-cell capacitive touch screen, obtaining noise values corresponding to different gray scales for each intersection, obtaining a theoretical noise value for each intersection under a condition of a current picture, and, for each intersection, compensating a detected signal with the theoretical noise value in the current picture to locate a position of the touch contact.
