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. Through the alternate use of the master scanning mode and slave scanning mode, the present invention is able to utilize the strengths of the master scanning and slave scanning are utilized to solve the issue that fails to be resolve by only one scanning mode used; in the meantime, the alternate use of the master scanning mode and slave scanning mode ensures the homogeneity of the data acquisition time, thus enabling the reliability of data; only part of the slave scanning mode is executed, so as to minimize the additional time consumption.
