Abstract: The present invention relates to touch screen technology, and provide a weight pressure process method and system of the self capacitive touch screen. In the weight pressure process method and system of the self capacitive touch screen provided by the invention, a threshold relationship is used to modify the existing touch threshold, the threshold relationship uses the touch threshold and the minor change of the changes of two channels adjacent to the channel corresponding to the maximum value as variables, if the maximum value is not greater than the value of the threshold relationship, identify the point causing the current change as a fake point and filter out the fake point. In the method, the change of the self capacitor caused by the deformation due to pressure, so the actual touch point can be identified more accurately, a touch application can be performed correctly, and the user experience is improved greatly.

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.

Abstract: A time slot scanning method that enables the capacitive touch screen to implement multiple scanning modes, where the said capacitive touch screen comprises the capacitance matrix and data processing modules that are electrically connected thereto; the said scanning method refers to a data acquisition mode where the signal scanning is initiated in a cycle and the received data generated due to scanning are acquired. The present invention enables the touch screen to execute multiple scanning modes with the time slot scanning method. Under the circumstances where the master scanning mode is executed, the scanning course of the slave scanning mode will be inserted in sections into the scanning course of the master scanning mode.
