Patent ID: 7095391

Claim:
A liquid crystal display (LCD), comprising: a scan signal line for supplying scanning signals to pixels configuring an LCD panel; a source signal line for supplying image signals to pixels configuring the LCD panel; a pixel switch for selectively providing the image signals to a third electrode from a first electrode connected to the source signal line depending on voltage state of a second electrode connected to the scan signal line; a power unit for respectively supplying first power and second power to all pixels from outside of a pixel area of the LCD panel; a control signal line unit including a first control signal line for transmitting a first control signal to all pixels from outside of the pixel area of the LCD panel, and a second control signal line for transmitting a second control signal to all pixels from the outside of the pixel area of the LCD panel; a liquid crystal unit for selectively transmitting light according to voltage difference between the image signals and the second power; and a memory cell unit for receiving the first control signal and the second control signal from the control signal line unit.
