摘要： A source driver adaptive to driving a plurality of data lines on a display panel is provided herein. The source driver includes a plurality of channels and an output switch. The channels generate driving voltages to drive the display panel. The output switch includes a plurality of output multiplexers, so as to selectively connect the channels to data lines of the display. Each of the output multiplexers connects at least one of the channels to one of the data lines while being activated, wherein the output multiplexers are sequentially activated within a frame period. The source driver utilizes the output switch to sequentially delay a control signal, for controlling the output multiplexers to be sequentially activated within the frame period. Therefore, an electromagnetic interference can be reduced for ensuring the source driver operates normally.

摘要： A power detecting device, a power supply device using the same, and a reference voltage generator are provided. The power detecting device adapted to detect a power voltage of a display device includes a bandgap voltage generating circuit, a voltage regulating circuit, and a power-on reset circuit. The bandgap voltage generating circuit provides a reference voltage via an output terminal thereof. The voltage regulating circuit and the power-on reset circuit are coupled to the output terminal of the bandgap voltage generating circuit. When the power voltage doesn't reach a threshold voltage, the voltage regulating circuit increases the reference voltage referred by the power-on reset circuit. When the power voltage reaches the reference voltage, the power-on reset circuit generates a reset signal to reset the display device. Therefore, when the power voltage doesn't reach a stable, the power-on reset circuit will not be incorrectly started by increasing the reference voltage.
