Patent number: 9793007Abstract: A bidirectional shift register capable of performing a stable shift operation in both directions and an image display device using the same are provided. In forward shift operation, when reference point N1 is at H level, (n+4)-th unit register circuit as a rear stage of the bidirectional shift register outputs pulse G(n+4) in synchronization with clock pulse V(n+4) inputted to (n+4)-th unit register circuit. A backward direction trigger signal VSTB is generated not only at the time of start of backward shift, but also, for example, in period (time t4 to t5) of one-phase clock immediately after G(n+4) is outputted in vertical blanking interval of the forward shift. The backward direction trigger signal VSTB is inputted to gate of a transistor provided to set reference point N1 of (n+4)-th unit register circuit to H level at the time of start of the backward shift.Type: GrantFiled: April 5, 2016Date of Patent: October 17, 2017Assignee: Japan Display Inc.Inventors: Takahiro Ochiai, Mitsuru Goto, Hiroyuki Higashijima, Yoshihiro Kotani, Shuuichirou Matsumoto
