    Abstract: A gate driver includes multiple stages. Each stage has a circuit portion and a wiring portion. The wiring portion delivers first and second clock signals to the circuit portion. Further, the wiring portion includes first and second clock wirings receiving the first and second clock signal, respectively, first connecting wirings electrically connecting the first clock wiring with a first every other stage, and second connecting wirings electrically connecting the second clock wiring with the odd-numbered stages. Further, the wiring portion includes third connecting wirings electrically connecting the first connecting wiring with a second every other stage and fourth connecting wirings electrically connecting the second connecting wiring with the even-numbered stages. This configuration may prevent the gate driver from operating erroneously and reduce power consumed by the gate driver.

    Abstract: A display device includes a display panel including data lines and scan lines coupled, a data driver configured to supply data voltages to the data lines based on digital video data, a scan driver configured to supply scan signals to the scan lines, a timing controller configured to select one of a normal mode and a self-refresh mode based on a panel self-refresh enable signal, where the data and scan drivers are driven by a first frame frequency in the normal mode and by a second frame frequency lower than the first frame frequency in the self-refresh mode, and a power supply source configured to supply driving voltages to the data and scan drivers and the timing controller and to transmits a direct current power voltage to an outside thereof, where a transmission of the direct current power voltage is blocked during a blank period in the self-refresh mode.
