A gate driving circuit includes a plurality of shift registers coupled in series. An nth shift register includes a driving circuit and a pull-down circuit. The driving circuit is electrically coupled to an output node and a first node. The driving circuit is configured to receive a first clock signal and output a gate signal according to the first clock signal. The pull-down circuit is electrically coupled to the output node. The pull-down circuit is configured to receive an (n&#x2212;m)th gate signal and an (n+m)th gate signal, and pull-down the gate signal to a low voltage level according to one of the (n&#x2212;m)th gate signal and the (n+m)th gate signal, wherein m and n are positive integers.

Gate driving circuit

A display device includes a plurality of pixel electrodes arranged in an array. A first switch electrically connected to a first pixel electrode of the pixel electrodes. A second switch electrically connected to a second pixel electrode of the pixel electrodes. The second switch is electrically connected between the first switch and a data line, and the first pixel electrode and the first pixel electrode are respectively located at two row of the pixel electrodes that are not adjacent to each other.

Display device with improved pixel electrode charging

A display apparatus includes a pixel array, a data line and a data driver. The pixel array has adjacent first and second pixels disposed in different rows. The data line transmits first and second pixel voltages to be written into the first and second pixels respectively. The first and second pixel voltages are employed to illustrate a same frame. The data driver is utilized for generating the first and second pixel voltages furnished to the data line based on input image data. The data driver includes a voltage analysis unit and a voltage setting unit. The voltage analysis unit is used for calculating a voltage difference between the first and second pixel voltages, and for comparing the voltage difference with a preset value so as to generate a control signal. The voltage setting unit is utilized for setting the voltage of the data line according to the control signal.
