Patent number: 7764761Abstract: A shift register apparatus and a method thereof are provided. The technique manner submitted by the present invention utilizes two NMOS transistors for pulling down the voltage level of the scan signals output by the shift registers within the shift register apparatus to the low level gate voltage, wherein one of the NMOS transistors is controlled by a control unit, and the other NMOS transistor is controlled by a clock signal or the inverted clock signal provided to the shift registers. Therefore, shifting amount of the threshold voltage of those NMOS transistors can trend to be flat, and the reliability of those NMOS transistors can be promoted. In addition, since only one control unit is needed to dispose in each shift register so that the layout area of whole shift register apparatus can be reduced, and the panel with narrow frame size also can be achieved by the present invention.Type: GrantFiled: August 7, 2008Date of Patent: July 27, 2010Assignee: Chunghwa Picture Tubes, Ltd.Inventors: Chih-Jen Shih, Chun-Yuan Hsu, Che-Cheng Kuo, Chun-Kuo Yu
