Abstract
A touch screen device incorporating a display and a capacitive touch sensor. The device has a mode of operation in which a single touch sensor measurement is made up of multiple charge accumulations, which take place in different display cycles, 'H-sync', and whose time windows, defined by switch 'S', commence with different time delays, 0, Δtand (Δt+Δt) from the drive pulse edge, ‘drive’, whose induced charge transfer they are accumulating. By subdividing the measurement into multiple charge accumulations, the amount of time needed in each display cycle for performing the touch sensor measurement can be reduced to avoid coinciding with periods of high display-induced noise.
