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.

Abstract: A display device and a shutdown control method thereof are provided. In the display device, a display panel has multiple pixels. A power supply circuit generates a power supply voltage, a gate high voltage and a common voltage according to an input power. A gate driver generates gate scan signals, and a source driver provides source driving signals to drive the display panel. A shutdown detection circuit detects a variation state of voltages values of the power supply voltage, the input voltage and the gate high voltage, and starts a shutdown process when the variation state is a decreasing state. In the shutdown process, the source driver makes the source driving signals to be equal to a reference ground voltage, the gate driver generates the gate scan signals with a high voltage pulse, and the power supply circuit makes the common voltage to be equal to the reference ground voltage.

Abstract: A display apparatus and a driving method thereof are provided. A data driving chip provides a plurality of data voltages to a plurality of multiplexers through a plurality of output lines. When the display apparatus displays a pure gray pattern, the data voltages are alternately provided to a first data line group and a second data line group during a scan line driving period of each of the scan lines to make two adjacent pixels have different polarities. During a blank period, a plurality of data lines corresponding to a plurality of pixels having the same color and the same polarity on two adjacent scan lines are electrically coupled to each other through the data driving chip to share charges.
