Patent ID: 7544969

Claim:
A display device comprising: a display panel including a plurality of pixel parts, each pixel part comprising: a transmissive part in which a transmission voltage transmitted through a source line according to activation of a first gate line is charged; a reflective part in which the transmission voltage is charged; and an adjusting part that adjusts the transmission voltage charged in the reflective part to a reflection voltage based on a control voltage transmitted through the source line according to activation of a second gate line; a gate driving part outputting first and second gate signals to the first and second gate lines respectively, the first and second gate signals activating both the first and second gate lines in a first period, and activating only the second gate line in a second period; a source driving part outputting the transmission voltage in the first period; and an output selecting part outputting the transmission voltage to the source line in the first period, and selectively outputting the control voltage to the source line in the second period.
