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.
Abstract:
A tool cabinet includes a cabinet body, a drawer received by the cabinet body, and an opening and closing device engaged with the cabinet body and the drawer. The opening and closing device includes a first and second holder, a displacing member, a flipping member, and a biasing member. The displacing member is restrained by the first and second holders and is adapted to be inserted into a recessed structure defined by the cabinet body. The displacing member is biased by the biasing member. The flipping member is restrained by the first holder and is pivotal relative thereto. The displacing and flipping members include a first and second slant surface in contact with each other. Upon pivoting the flipping member, the displacing member is adapted to be moved. The drawer is prevented from being opened when the displacing member is inserted into the recessed structure.
Abstract:
A slanted guide drawer opening and closing device separately installed to both sides of a front panel of a drawer includes a displacing member installed and passing transversally into a holder, and the displacing member has a first slant surface, and a flipping member with a second slant surface, and the flipping member and the displacing member abut each other through the first and second slant surfaces. The flipping member is flipped to produce a displacement, so that the displacing member produces a transverse displacement. An end of the displacing member is pushed by the flipping member to extend out from the holder and blocked by a stop portion disposed in a drawer cabinet, so that the drawer is situated in a closed status and cannot be pulled out.
