Abstract

The invention relates to a touch system and a method for increasing report rate. A readout circuit sequentially transmits driving signals to at least each two first sensing lines of a plurality of first sensing lines of a touch panel. The report rate increasing touch system comprises the touch panel and the readout circuit. The touch panel is used for being touched by at least one object, a first axial direction of the touch panel is provided with N first sensing lines, and a second axial direction of the touch panel is provided with M second sensing lines. The readout circuit is used for sequentially transmitting the driving signals to at least each two first sensing lines of the N first sensing lines, sequentially receiving sensing signals corresponding to the at least each two first sensing lines through the M second sensing lines, and calculating and outputting the coordinate of the at least one object touching the touch panel to a main unit according to the sensing signals corresponding to the at least each two first sensing lines, wherein the driving signals corresponding to the at least each two first sensing lines are partially superposed.

Description

technical field [0001] The present invention relates to a touch control system and a method for increasing the report rate of the touch system, especially to a method for sequentially detecting a plurality of first sensing lines of a touch panel by using a readout circuit. Every at least two first sensing lines emit driving signals at the same time, so as to improve the touch control system and method of reporting rate. Background technique [0002] Among the existing touch panels, the mutual capacitive touch panel is the mainstream touch panel. Please refer to FIG. 1 . FIG. 1 is a schematic diagram illustrating a mutual capacitive touch panel 100 . As shown in FIG. 1, when the driving method of the touch panel 100 is to scan the voltage or current in the Y-axis direction (or X-axis direction), and then intercept the touch point in the X-axis direction (or Y-axis direction). sensing signal. The Y-axis direction scans sequentially from the sensing line Y1 to the sensing li...
