Abstract
The application discloses a touch detection method, a touch detection apparatus and a touch screen system. The touch detection method utilizes a closure strategy to close certain detection processes among three detection processes comprising a Y-direction electrode array detection, an X-direction electrode array detection and an XY-direction electrode array detection. Specifically, when it is detected in one of the three detection processes that no touch signal is generated on the touch screen, the other two of the three detection processes are not to be started; when it is determined that the touch signal on the touch screen is a multi-touch signal, one of the Y-direction electrode array detection and the X-direction electrode array detection that has not been executed is refrained from being started.
