Patent ID: 8736180

Claim:
An organic light-emitting diode (OLED) display, comprising: an OLED panel having a display region formed by a plurality of pixels, the display region being divided into a first sub-display region and a second sub-display region; a first conducting wire disposed on the OLED panel and out of the display region, and a first terminal of the first conducting wire being electrically coupled to each of the pixels in the first sub-display region; a second conducting wire disposed on the OLED panel and out of the display region, and a first terminal of the second conducting wire being electrically coupled to each of the pixels in the second sub-display region, wherein the length of the second conducting wire is longer than that of the first conducting wire so that the resistance of the second conducting wire is larger than that of the first conducting wire; and a power supply electrically coupled to a second terminal of the first conducting wire and a second terminal of the second conducting wire for providing a first voltage and a second voltage to the second terminal of the first conducting wire and the second terminal of the second conducting wire respectively, wherein the second voltage is larger than the first voltage so that the voltage of the first terminal of the second conducting wire is substantially the same with the voltage of the first terminal of the first conducting wire, wherein the second sub-display region is divided into a first sub-sub-display region and a second sub-sub-display region, the OLED display further comprises a third conducting wire disposed on the OLED panel and out of the display region, a first terminal of the third conducting wire is electrically coupled to each of the pixels in the second sub-sub-display region, and the first terminal of the second conducting wire is changed to be electrically coupled to each of the pixels in the first sub-sub-display region, the length of the third conducting wire is longer than that of the second conducting wire so that the resistance of the third conducting wire is larger than that of the second conducting wire, the power supply is further electrically coupled to the second terminal of the third conducting wire to provide a third voltage to the second terminal of the third conducting wire, the third voltage is larger than the second voltage so that the voltage of the first terminal of the third conducting wire is substantially the same with the voltage of the first terminal of the second conducting wire.
