<P>PROBLEM TO BE SOLVED: To provide a current mirror for driving an OLED panel, wherein currents with high uniformity can be supplied to the OLED panel so as to be able to improve the performance of the OLED panel. <P>SOLUTION: The current mirror adopts low voltage MOS transistor as the primary part of the current mirror so as to provide currents with high uniformity to the OLED panel. Further, the current mirror also utilizes high voltage devices to bias the current mirror so that the high voltage used for the OLED panel is used for the current mirror. <P>COPYRIGHT: (C)2007,JPO&INPIT |
