Abstract: A driving device is configured for driving a display panel and includes a data driver, a plurality of switches, and an image determiner. The switch is electrically coupled between data lines of a first data line group. The data driver is configured to output data signals to the data lines of the first data line group. The data signals transferred by the data lines of the first data line group include a plurality of pulse transitions while the display panel displays an image. The image determiner is configured to determine the image displayed by the display panel and output a driving signal based on a determined result for activating a corresponding switch such that the data lines of the first data line group can perform charge sharing therebetween. Furthermore, a method for driving a display panel is disclosed herein.

Abstract: A high gate voltage generator and a display module are provided. The high gate voltage generator includes a pulse width modulation (PWM) signal generating circuit, a boost circuit, and an amplifier circuit. The PWM signal generating circuit is used for outputting a PWM signal. The boost circuit is electrically connected to the PWM signal generating circuit and used for receiving an input voltage to boost the input voltage according to the PWM signal and then outputting a power voltage. The amplifier circuit is electrically connected to the boost circuit and used for receiving a reference voltage to amplify the power voltage and then outputting a high gate voltage. The reference voltage is greater than the high gate voltage and is provided by a backlight module electrically connected to the amplifier circuit.
