Claim Text:
1. A pixel comprising: a plurality of organic light emitting diodes, each of which comprising a cathode electrode coupled to a second power source; a pixel circuit coupled to a scan line and to a data line, the pixel circuit configured to control current supplied from a first power source to the organic light emitting diodes corresponding to a data signal supplied to the data line; and first transistors between the pixel circuit and respective ones of the organic light emitting diodes, the first transistors configured to be turned on or to be turned off when a low emission control signal is supplied to a first emission control line, wherein a scan signal supplied to the scan line is a first voltage, wherein the low emission control signal is a second voltage that is different than the first voltage, and wherein the first transistors are implemented as same channel type transistors.
