Light emitting device display circuit and drive method thereof
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.
