The pixel driving circuit has two or more current paths through a plurality of switching elements for providing the necessary current to the OLEDs in a pixel. The control end of each switching element is connected to the control end of the other switching elements, but each switching element has a separate power source which can be separately adjustable. In some embodiments, in a pixel or sub-pixel, one switching element is located at one end and one switching element is located at the other end of a pixel length, and each pixel is adjacent to a first power source line and a second power source line along the pixel length for separately providing the electrical power to two switching elements.
