Abstract:
     The present invention relates to pixel structure and drive method for active matrix type organic light emitting display. The pixel structure consists of four transistors, one capacitor and three signal lines, where the first transistor and the second transistor act as switching transistors controls with the first scanning line and the second scanning line; and the third transistor and the fourth transistor constitute one current mirror to make the current through each organic LED in each of the pixel equal to the current written through the data line. Therefore, the organic LED's in different pixels are homogeneous without being affected by the critical voltage.
