Multiple conducting channels in a display pixel, controlled by a single
access electrode are provided in the present invention. Such pixel
circuits operate to set a pixel data voltage by directing a data current
to one of the conducting channels, while deliver a drive current to the
light emitting device in a pixel via the other conducting channel.
Current-controlled drive scheme, independent of threshold voltage, is
achievable in the present invention without substantial increase in pixel
complexity. Such merged pixel structures provide simplicity and greater
flexibility in implementing current drive pixel structure.
