    摘要: A gate driving circuit for providing a high driving voltage includes a first N-type high-voltage transistor and a second N-type high-voltage transistor connected in series between a driving voltage output node and a system low-voltage source. A voltage difference between a system high-voltage source and the system low-voltage source is greater than a withstand voltage of the first or second N-type high-voltage transistor. When the driving voltage output node is to output a system high voltage, the first N-type high-voltage transistor and the second N-type high-voltage transistor are turned off. Deep N-type well regions of the first N-type high-voltage transistor and the second N-type high-voltage transistor are applied with a first bias voltage. A voltage difference between the first bias voltage and the system low-voltage source is smaller than an interface breakdown voltage between the deep N-type well region and a P-type well region of the second N-type high-voltage transistor.

The timing controller includes a refresh mark controller and a pixel controller. The refresh mark controller includes a refresh mark table, and a plurality of refresh marks in the refresh mark table correspond to a plurality of sub-regions of a display region in the display panel. The refresh mark controller determines whether the sub-regions need to be refreshed according to an image signal and responds to a specific sub-region required to be refreshed to adjust a specific refresh mark according to a mapping ratio. The pixel controller sequentially looks up whether the refresh marks in the refresh mark table are adjusted, obtains the sub-regions corresponding to the adjusted refresh marks according to the mapping ratio, and performs a pixel refresh operation to the sub-regions.

    摘要: A position apparatus of a touch device and a position method thereof are provided, wherein the touch device includes a plurality of scan lines. In the position method, a plurality of capacitances in the scan lines are sensed. Next, a plurality of capacitances respectively sensed in an ith scan line of the scan lines and a subset of the scan lines neighboring with the ith scan line are selected. When the capacitance sensed in the ith scan line is larger than each of the capacitances sensed in the subset of the scan lines, the capacitance sensed in the ith scan line is determined as a peak capacitance. Finally, a touch position is calculated according to the peak capacitance and the capacitances sensed in the subset of the scan lines.
