Patent ID: 7619602

Claim:
A display device comprising: a display area including a plurality of data lines for transmitting data currents for displaying images, and a plurality of pixel circuits coupled to the data lines; a plurality of first signal lines; a data driver coupled to the first signal lines for time-dividing a first current corresponding to the data currents and transmitting the time-divided first current to the first signal lines; a demultiplexer unit including a plurality of demultiplexers for respectively receiving the first current from the first signal lines and transmitting the data currents to at least two data lines; and a precharge unit coupled between the demultiplexer unit and the data driver for transmitting a precharge voltage to the first signal lines before the data driver transmits the time-divided first current to the first signal lines for each of the data currents, wherein each of the pixel circuits includes a transistor to which the data current flows from a corresponding one of the data lines, a capacitor coupled between the source and the gate of the transistor and for storing a voltage corresponding to the current flowing to the transistor; and a light emitting element for emitting light corresponding to the current flowing to the transistor according to the voltage stored in the capacitor.
