Abstract
An n-th stage array substrate row driving unit of a row driving circuit for an array substrate is provided. The n-th stage array substrate row driving unit comprises an (n−3)-th and an (n−2)-th stage signal input terminal and a pull-up controlling unit. The pull-up controlling unit is a first thin film transistor and is connected to the (n−2)-th and a (n−3)-th stage signal input terminal. A peak voltage of the (n−3)-th stage signal input terminal is twice a peak voltage of the (n−2)-th stage signal input terminal. Thus, the threshold voltage shift of the TFT elements can be avoided, and the stability of the output can be improved.
