  • Patent number: 9257978
    Abstract: A multiplex driving circuit receives m master signals and n slave signals, and includes m driving modules for generating m×n gate driving signals. Each driving module includes a voltage boost stage and n driving stages. The voltage boost stage is used for receiving a first master signal of the m master signals and converting the first master signal into a first high voltage signal, wherein a high logic level of the first master signal is increased to a highest voltage by the voltage boost stage. The n driving stages receives the n slave signals, respectively, and receives the first high voltage signal. In response to the highest voltage of the first high voltage signal, the n driving stages sequentially generates n gate driving signals according to the n slave signals.

  • Patent number: 8476932
    Abstract: A multiplex gate driving circuit includes plural driving modules. In comparison with the prior art, each driving stage of the driving module has less number of transistors. From the first to the seventh example, each driving stage is implemented by only four transistors. In the eighth example and the ninth example, each driving stage is implemented by only two transistors. In other words, the driving stage of the multiplex gate driving circuit has less number of transistors, thereby reducing the layout area of the invisible zone of the LCD panel.

  • Publication number: 20120113070
    Abstract: An arrangement method, applied to a plurality of gate driver modules coupled in series and arranged on two sides of a panel, includes steps of: placing a first gate driver module on a first side of the panel; placing a gate driver set on a second side of the panel; and placing a fourth gate driver module on the first side of the panel. The gate driver set includes a second gate driver module and a third gate driver module serially connected. The output terminal of the first gate driver module is electrically coupled to the second gate driver module and the output terminal of the third gate driver module is electrically coupled to the fourth gate driver module. A gate driver circuit and an arrangement method applied to a plurality of shift register sets coupled in series and arranged on two sides of a panel are also disclosed.
