  • Publication number: 20040207590
    Abstract: A display driving circuit having a plurality of driving stages and driving lines is provided. The driving stages are electrically coupled in serial, and each of the driving stages comprises a conducting path for transmitting an electric signal from the previous driving stage to the next driving stage via the current driving stage. Each of the driving lines respectively corresponds to a driving stage and electrically connects to an output terminal of the corresponding driving stage. The display driving circuit is characterized in that a redundant device is only installed in one part of the driving stages. The redundant device is capable of supplying an extra conducting path to transmit an electric signal from the previous driving stage to the next driving stage via the current driving stage while the original conducting path in the corresponding driving stage is broken.

  • Publication number: 20040190672
    Abstract: A bi-directional shift-register circuit for outputting data in different sequence. A first shift-register unit includes a first-stage control terminal and a first-stage output terminal outputs a first output signal. A second shift-register unit includes a second-stage input terminal coupled to the first-stage output terminal and a third-stage output terminal, a second-stage control terminal and a second-stage output terminal outputs a second output signal. The second-stage control terminal is selectively coupled to the first-stage output terminal and the third-stage output terminal and disables the second shift-register unit according to the first output signal or a third output signal. A third shift-register unit includes a third-stage control terminal and the third-stage output terminal outputs the third output signal.
