Abstract:
A method for fabricating a low temperature polysilicon organic electroluminescent display panel, comprising the following steps:providing a substrate; forming an amorphous silicon layer on said substrate; forming a plurality of patterned transistor element each having a patterned source, a patterned drain and a patterned gate on said amorphous silicon layer through photolithography and ion doping; annealing said transistor elements having said patterned sources, said patterned drains and said patterned gates by direct radiation of excimer laser; forming a plurality of patterned stripes of second conductive lines connected to said gates on the surface of said substrate; forming a patterned isolation layer on said gate layer and part of said second conductive lines, and also forming a plurality of patterned stripes of first conductive lines and a patterned first electrode on said substrate wherein said first and said second conductive lines sandwich said isolation layer, said first conductive lines are connected to said sources and said first electrode is connected to said drains; forming at least one organic electroluminescent medium on said first electrode; and forming a second electrode layer on said organic electroluminescent medium; wherein said first conductive lines and said second conductive lines are intersected without direct electrical contact.
