Patent number: 7483012Abstract: Disclosed is an LCD having an integrated amorphous-silicon TFT row driver. The LCD includes at least one shift register integrated in an LCD panel. The LCD uses a reset signal by shifting phase of gate drive pulse in a gate line direction according to a clock period. The LCD has a 1-bit shift register having a dummy function formed at a final terminal of the shift register. An input signal of drive pulse is used as the reset signal of a shift register formed at a final terminal of a shift register row.Type: GrantFiled: December 24, 2003Date of Patent: January 27, 2009Assignee: Hydis Technologies Co., Ltd.Inventors: Se Jong Yoo, Cheon Hong Kim
