Patent ID: 8022900

Claim:
An organic light emitting diode (OLED) display, comprising: a pixel comprising four sub-pixels each displaying a different color; two gate lines transmitting gate signals to the pixel and having first control electrodes extended from the two gate lines; a second control electrodes separated from the two gate lines; a semiconductor at least partially overlapping the second control electrode; two data lines transmitting data signals to the pixel; and a driving voltage line transmitting a driving voltage to the pixel, wherein the driving voltage line includes a first portion extending substantially parallel to the two data lines, wherein the semiconductor comprises a portion at least partially overlapping the first portion of the driving voltage line, and wherein the first portion of the driving voltage is divided into a left side that corresponds to two left sub-pixels of the four sub-pixels and a right side that corresponds to two right sub-pixels of the four sub-pixels and that a portion of the semiconductor that corresponds to the two left sub-pixels overlaps a portion of the left side of the first portion of the driving voltage line and does not overlap the right side of the first portion of the driving voltage line.
