CAPACITIVE TOUCH DEVICE

摘要

There is provided a capacitive touch device including a controlling and processing circuit and a touch panel. The touch panel has a plurality of detection cells arranged in matrix. The controlling and processing circuit is configured to input a drive signal to the detection cells of the touch panel and read measurement data from the detection cells for post-processing, wherein the controlling and processing circuit reads a first sampling number of the measurement data of the detection cells in a normal mode and a second sampling number of the measurement data of the detection cells in a sleep mode, and the second sampling number is lower than the first sampling number.
