Patent ID: 7924247

Claim:
A display device comprising: a plurality of data lines; a transmission gate element comprising a first transmission gate, a second transmission gate, and a third transmission gate each supplying a precharqe voltage and a data voltage to each of the data lines in response to a transmission gate signal; a first transmission gate signal line connected to the first transmission gate, a second transmission gate signal line connected to the second transmission gate, and a third transmission gate signal line connected to the third transmission gate, wherein the first, second and third transmission gate signal lines transmit the transmission gate signal; and a plurality of pixels connected to the data lines, wherein a pixel of the plurality of pixels includes a capacitor, wherein the first, second and third transmission gates are simultaneously turned on to apply the precharge to the data lines in a first period, and then, the first, second and third transmission gates are sequentially turned on to apply the data voltages to the data lines in a second period, and a reference voltage is applied to the capacitor in a third period following the second period.
