Abstract
A GIP circuit, a method for driving the GIP circuit and a flat panel display device incorporating the GIP circuit. The GIP circuit is simple in structure and is capable of producing GIP signals that can be neatly pulled from a high level down to a low level. This allows better driving, avoids ripples and achieves higher display quality of the flat panel display device.
