Patent number: 9411469Abstract: A driving circuit outputs driving waveforms to operation signal lines. The waveforms are formed by combining a first-mode waveform for charging a node capacitor with a positive voltage and a second-mode waveform for charging the node capacitor with a negative voltage in a predetermined binary sequence. A sensing circuit is electrically connected with a plurality of sense signal lines and measures sense voltages delivered to one integration capacitor from a plurality of node capacitors which are electrically connected with the sense signal lines. A sense detector adds or subtracts the sense voltages which are measured by the sensing circuit at driving time points to measure capacitances of the node capacitors. Accordingly, an autocorrelation technique which is generally used in communication systems is applied to driving a touch screen device.Type: GrantFiled: August 18, 2015Date of Patent: August 9, 2016Assignee: ZINITIXInventors: Il Hyun Yun, Hyung Cheol Shin
