Abstract:
A three-level-driven array substrate row driving circuit includes cascaded multi-level array substrate row driving units. The n-th level array substrate row driving unit includes a clock signal input, a (n−1)-th level signal input, a (n+1)-th level signal input, a (n+3)-th level signal input, a first low level input, a second low level input, and a signal output. The n-th level array substrate row driving unit further includes a pull-up driving unit, a pull-up unit, a first pull-down unit, and a second pull-down unit. The three-level-driven array substrate row driving circuit contributes to reduce the manufacturing cost of the liquid crystal panel and the narrow border design. By adopting the three-level-driven method, the impact caused by the feed-through voltage, which is generated by the data line and the gate line, toward the TFT LCD is effectively eliminated such that the display performance is enhanced.
