Patent ID: 7221337

Claim:
An electro-luminescence display device, comprising: a first electro-luminescence diode for a first pixel for displaying a first color, the first electro-luminescence diode having a first electrical characteristic; a second electro-luminescence diode for a second pixel for displaying a second color, the second electro-luminescence diode having a second electrical characteristic; a first driving circuit which receives a first driving voltage and applies a first driving current to the first electro-luminescence diode; a second driving circuit which receives a second driving voltage equal to the first driving voltage and applies a second driving current different from the first driving circuit to the second electro-luminescence diode, a difference between the first driving current and the second driving current being set based on a difference between the first electrical characteristic of the first electro-luminescence diode and the second electrical characteristic of the second electro-luminescence diode; a first data line supplying a first data voltage to the first driving circuit; a second data line supplying a second data voltage to the second driving circuit; a first power supply line supplying a first common voltage to the first driving circuit; and a second power supply line supplying a second common voltage to the second driving circuit, wherein the first data voltage and the second data voltage are substantially equal, the first common voltage and the second common voltage are substantially equal, and the first driving current and the second driving current are different.
