Abstract
The present disclosure relates to a method for filtering touch noise and a touch device. The method includes: when normal signals for at least one row of the touch electrodes are input to the touch panel, obtaining a standard capacitance value of each of the touch electrodes, and obtaining a connection capacitance value of each of the touch electrodes; for each of the touch electrodes: subtracting a connection capacitance value of another touch electrode, which is in the same row with and adjacent to the touch electrode in a first direction, from the connection capacitance value of the touch electrode to obtain a capacitance difference value; from the last touch electrode, calculating the capacitance value of the restoration signal for each touch electrode along a second direction opposite to the first direction. Coordinates are calculated according to the capacitance values of the restoration signals for individual touch electrodes.
