1. An integrated current driver structure for an active matrix OLED, comprising:
- a panel;
a pixel matrix consisting of a plurality of pixels arranged in matrix on the panel;
a current driver having a plurality of driver units arranged in a row on the panel, wherein an output of the driver unit is connected to a column of pixels by a data line;
a plurality of current controllers in charge of refreshing sequence of current data of the current driver;
a plurality of current input lines, each of which is connected to an input of one driver unit; and
a scan driver connected to the pixels in charge of refreshing sequence of current data of the pixels in a row. The scan driver may be integrated on the panel or impleamented outside the panel with driver ICs.
