The impact of stress effect to the performance of an IGZO panel is discussed in this paper. Depart from conventional method of observing the threshold voltage (V th ) shift, the time dependency of serial I D ‐V G test is included in building an accurate V th shift model. The model can be used to simulate the IGZO TFT current change under fixed bias for aiding the circuit design and optimization.
