Abstract text


An AMOLED panel includes an AMOLED pixel unit, a scan driving unit and a data driving unit. The scan driving unit is coupled to the AMOLED pixel unit. The data driving unit is coupled to the AMOLED pixel unit and a voltage source. The data driving unit comprises a reference current source circuit, (N+1) mirror output circuits and (N+1) switch elements. The reference current source circuit is for providing a reference current. (N+1) mirror output circuits are coupled to the reference current source circuits for outputting (N+1) corresponding data currents to the AMOLED pixel unit, wherein N is a positive integer. The m-th data current of the (N+1) data currents is 2m times of the reference current, and m is an integer 0˜N. The switch elements are disposed in correspondence with the mirror output circuits for controlling the data currents to be outputted to the AMOLED pixel unit.
