Abstract: A touch display panel including scan lines, data lines, pixel units electrically connecting the scan lines and the data lines, at least a sensing-signal line locating between the pixel units, and at least a touch-sensing device is provided. Each touch-sensing element includes a set of sensing pads and a signal transmission element. The set of the sensing pads includes a first pad and a second pad separated from each other. The first pad and the second pad are respectively electrically connected to the scan line and the sensing-signal line. The signal transmission element is located above the set of the sensing pads. When a position where the touch-sensing element is disposed is pressed, the signal transmission element directly contacts the first pad and the second pad. When the position where the touch-sensing element is disposed is unpressed, the first pad and the second pad are electrically insulated.

Abstract: A digital to analog converter is provided comprising a charge sharing circuit, a discharging circuit and a voltage boosting circuit. The charge sharing circuit sequentially receives first to (N-1)th bits of serial digital signals. The charge sharing circuit shares and stores charges between a first capacitor and a second capacitor according to a charging voltage, a ground voltage, a first clock signal and serial data signals. The discharging circuit discharges the charge sharing circuit according to a reset signal. After the voltage boosting circuit receive the (N-1)th digital signal, the charge boosting circuit whether to boost a first terminal and a second terminal of the second capacitor or not based on an Nth digital signal. After the voltage boosting circuit receives the Nth serial digital signal, the charge sharing circuit outputs an analog signal from the second terminal of the second capacitor.

Abstract: A circuit board includes a power switch operable so as to generate a trigger signal upon actuation, a card slot adapted for connecting with a video card, and a controller coupled electrically to the power switch and the card slot. The controller detects connection of the video card to the card slot and further detects operating voltage of the video card. The controller inhibits the power switch from generating the trigger signal upon detection that the operating voltage of the video card that is connected to the card slot is higher than a predetermined voltage.
