Patent ID: 7126566

Claim:
A driving circuit for driving an active matrix organic electro-luminescence display panel which is composed of pixels arranged in columns and rows; columns of pixels are divided as a block controlled by the block control line; the driving circuit of each pixel comprising of: a writing TFT having a gate connected to a scan line and having a drain connected to a data line; a switching TFT having a drain connected to the source of the writing TFT and having a gate connected to the block control line; a resetting TFT having a drain connected to the source of the switching TFT and having a source connected to a supply line and a gate connected to the front scan line, wherein the gate of resetting TFT of all pixels on the first scan line is connected to a Start-Erase Line; a storage capacitance with one end connected to the supply line and another end connected to the joint where the source of switching TFT meets the drain of resetting TFT; a driving TFT whose source connected to the supply line. Its gate, the same as one end of storage capacitance is connected to the joint where the source of switching TFT and the drain of resetting TFT meet; a organic electro-luminescence element with the positive electrode connected to the drain of the driving TFT and the negative electrode grounded.
