Abstract
In this paper, the certain relation between threshold voltage and flat‐band voltage to improve the image sticking for AMOLED display was investigated. Flat band state generally refers to a state in which the energy bands of each region in an ideal MOSFET system are flattened. However, it is requiring an additional voltage to flatten the energy band for actual MOS systems due to the difference in metal and semiconductor work function, which is called the flat‐band voltage. It is investigated that this flat‐band voltage is strongly linked to the short‐term image sticking.
