Title: Shift register and image display device
Inventor: WASHIO HAJIME
IPC: G09G3/36
Filed: 2000-10-27
Granted: 2003-06-21
Abstract: In a shift register provided with flip-flops that operate in synchronism with a clock signal, and a switching means, which is opened and closed in response to an output of the preceding stage of each of the flip-flops, is installed. The clock signal is selectively inputted by the switching means, and the selected clock signal is inverted and used as a shift register output from each of the stages. Moreover, two kinds of clock signals, each of which has a duty ratio of not more than 50% and which have no overlapped portions in their low-level periods, are used so as to prevent the outputs of the shift-register from overlapping each other. Thus, it is possible to provide a shift register which is preferably used for a driving circuit of an image display device, can miniaturize the driving circuit, and can desirably change the pulse width of the output signal, and also to provide an image display device using such a shift register.
