Abstract: A display driving device is provided. The display device includes a first data line, a first switch, a first storage unit, and a data output unit. The first switch is electrically connected between the first data line and the data output unit, and the data output unit is further electrically connected to the first storage unit. In a first closing period of the first switch, the data output unit outputs a first data signal to the first data line through the first switch, and the first storage unit stores the first data signal received from the data output unit. After the first closing period and before a second closing period of the first switch, the first storage unit charges the data output unit with the first data signal so that the data output unit and the first data line are at the voltage level.

Abstract: A display panel includes multiple data lines, a scan lines, pixel circuit and a driving circuit. The data lines are configured to receive multiple data signals in a display period. There is a buffer period before the display period. The scan line is configured to receive a scan signal during the display period. The pixel circuit is electrically connected to the data lines and the scan line for receiving the data signals and the scan signal. The driving circuit is electrically connected to the data line, and configured to receive multiple charging signals during the buffer period. The charging signals are corresponding to the data lines and gradually increase so that the driving circuit charges the data lines according to the charging signals.

Abstract: A multiplexer circuit includes a first switch unit and a second switch unit. The first switch unit is electrically connected to a first data line and a first pixel circuit, and configured to turn on according to a first signal in a first time duration. The second switch unit is electrically connected to the first data line and a second pixel circuit, and configured to turn on according to a second signal in a second time duration. The first time duration and the second time duration substantially start or end at a same time, so that the first time duration and the second time duration have overlap.

Abstract: The present disclosure provides a source driver module for driving a display panel. The source drive module includes a source driver circuit, a first conductive wire and a first switch unit. The first conductive wire is electrically connected to the source driver circuit. The first switch unit is connected between the first conductive wire and a first data line of the display panel to conduct current therebetween during a first data outputting period and a second data outputting period, and to interrupt current therebetween during a first switch-off period connecting the first data outputting period and the second data outputting period. The source driver circuit outputs a first voltage signal during the first data outputting period and the first switch-off period; it outputs a second voltage signal during the second data outputting period; and it outputs the first voltage signal during the first switch-off period.

Abstract: A display device includes an output circuit, a multiplexer, and a controller. The output circuit is configured to output a data voltage to an output pin. The multiplexer is configured to sequentially output the data voltage to different data lines according to a first multiplexing signal and a second multiplexing signal. The controller is configured to generate a control signal according to a variation of the data voltage to make the output pin output a default voltage level different from the data voltage corresponding to the data voltage.
