  • Patent number: 8786538
    Abstract: A display device comprises a display panel including data lines and gate lines crossing each other, a data driving circuit configured to convert digital video data into data voltages which are supplied to the data lines, a gate driving circuit configured to sequentially supply gate pulses to the gate lines, wherein a voltage of each of the gate pulses increases from a gate low voltage to a precharging voltage during a first rising time and thereafter increases from the precharging voltage to a gate high voltage during a second rising time, and wherein the voltage of each of the gate pulses decreases from the gate high voltage to the precharging voltage during a first falling time and thereafter decreases from the precharging voltage to the gate low voltage during a second falling time.
    Type: Grant
