Abstract:
An engaging structure of the drawer of a closet includes a fixing element on any one of the two opposite sides of the drawer that have sliding rails. One end of the fixing element is provided with a first guiding part corresponding to the end edge of the lift handle disposed on the front side of the drawer. The other end of the fixing element has an engaging part to engage with a stopping part when the drawer is put into the closet. To pull or push the drawer out of or into the closet, the user uses the lift handle to control the engagement or departure between the engaging part and the stopping part.
Abstract:
A touch apparatus including a touch panel and a touch sensing circuit is provided. The touch panel includes a first transparent substrate, a plurality of first conductive patterns, a second transparent substrate, a plurality of second conductive patterns and a plurality of spacers. The touch sensing circuit includes a first demultiplexer, a second demultiplexer, a first multiplexer, a second multiplexer, a third multiplexer, a fourth multiplexer, a fifth multiplexer, a sixth multiplexer and an analog/digital converter (ADC). The fifth multiplexer and the sixth multiplexer are used for modulating a signal receiving range of the ADC and thus the touch sensing circuit is easily judge a correctness of a sensing signal.
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.
