Abstract

The basic principles and characteristics of capacitive touch screen were introduced. The touch-screen data processing algorithms were researched and one method was presented about the pixel mapping between capacitive touch screen and LCD. The edge error problem of the capacitive touch screen system was solved by coordinate correction and the edge com pensation parameters. Software test results show that a good user experience has been achieved.
