Abstract: A self-capacitive touch device includes a transparent substrate, multiple sensing electrodes and multiple trace lines. The sensing electrodes are alternately disposed on the transparent substrate, and each of the sensing units has a polygonal planar contour having M sides, where M is a positive integer equal to or greater than 4. A side of each of the sensing electrodes corresponds to sides of at least two of the remaining sensing electrodes. The trace lines are electrically connected to the sensing electrodes in a way that a part of segments of the trace lines are disposed in an active region of the self-capacitive touch device.

Abstract: A touch detecting method comprises: enabling a sample signal in a period between driving a previous gate line and a previous two gate line before a corresponding gate line of a sense unit, and sampling a readout signal in a corresponding readout line during a sample period corresponding to the enabled sample signal by a readout unit; using the sampled readout signal during the sample period by the readout unit as a sample reference signal; enabling a sense readout signal in a period between driving the corresponding gate line of the sense unit and a next gate line, and reading out the readout signal during a sense readout period corresponding to the enabled sense readout signal; using the readout signal during the sense readout period as a sense signal; and judging whether the sense unit is touched according to the sample reference signal and the sense signal.

Abstract: While correcting and recording initial touch points on a touch panel, a plurality of sensors on the touch panel are classified into a plurality of first sensing groups assigned with serial numbers, and a plurality of sensors of each the first sensing group are equally divided into a plurality of second sensing groups assigned with serial numbers. After detecting initial touch points on the touch panel, a plurality of headers are generated for the plurality of first sensing groups, and a data structure is generated for each of the sensors having detected initial touch points according to whether first sensing groups corresponding to the headers have the sensors having the detected initial touch points or not. At last, the initial touch points are filtered off from a plurality of detected touch points on the touch panel, according to initial touch point information recorded in loaded data structures.

Abstract: A signal processing method is employed to operate a touch panel having a first touch sensing unit and plural second touch sensing units adjacent to the first touch sensing unit. In the operation of the method, a first signal is generated through amplifying the first sensing signal of the first touch sensing unit by N times with N equal to the number of the second touch sensing units, a second signal is generated through summing up the second sensing signals of the second touch sensing unit, a difference signal is generated through subtracting the second signal from the first signal, a comparison result is generated through comparing the difference signal with a difference threshold, and finally the comparison result is utilized for judging whether a touch event is occurring to the first touch sensing unit.
