摘要：

We design and fabricate a high-speed, low-voltage, small-pitch, and robust integrated gate driver with organic thin-film transistors (OTFTs). The dual-gate OTFT devices have a field effect mobility of 0.78 cm2/Vs, and on/off current ratio above 108. A single stage of the gate driver consists of ten TFTs and two capacitors, with small pitch of 244 mu m. The fabricated circuit has a minimum pulse width of 5 mu s, which is compatible with full-high definition (FHD, 1920 x 1080) active-matrix displays with 60Hz frame rate. It can work at input swing of as low as 10V, with VGH2, VGH1, and VGL of 5V, 0V, and -10V respectively. With the threshold voltage shift under positive and negative bias stress, the gate driver shows output signals without significant degradation and demonstrates its high reliability through simulation.
