Abstract
A couple of gate drivers are fabricated with LTPS TFTs in this paper. In order to improve the stabilization of the circuit output, the three TFTs’ structure are utilized in the scan circuit and the method of inserting a TFT is adopted in the emission circuit. Moreover, high temperature operation at 85 °C within 240 hours and low temperature operation at −40 °C within 240 hours without failure show the useful stabilization of the proposed circuits. Finally, a 5.5‐in. QHD OLED panel on substrate was successfully demonstrated with the gate driver circuits.
