More Information
Summary:The present invention relates to a touch sensing system comprising first and second ROICs driving a touch screen partitively; and an MCU analyzing raw touch data received from the ROICs and calculating coordinates of each touch input position. The ROICs transceive a synchronization signal through one pin, alternately supply a driving signal to Tx lines of the touch screen in charge, and are synchronized with the driving signal to receive a touch sensor voltage through Rx channels of the touch screen in charge.
