  • Publication number: 20180080973
    Abstract: The present disclosure provides a gate driving circuit, a method for detecting the gate driving circuit, an array substrate and a display apparatus. The gate driving circuit comprises a plurality of cascaded gate driving units, access units, a first signal line and a second signal line. Each access unit is connected to its corresponding gate driving unit and the gate driving unit at the next stage to its corresponding gate driving unit. The access unit corresponding to the gate driving unit at each odd stage is connected to the first signal line such that the first signal line detects an output signal from that gate driving unit via the access unit, and the access unit corresponding to the gate driving unit at each even stage is connected to the second signal line such that the second signal line detects an output signal from that gate driving unit via the access unit.

  • Publication number: 20170263184
    Abstract: The present disclosure provides a pixel driver circuit, a pixel circuit, a display panel and a display device. The pixel driver circuit includes two pixel driving units having an identical structure. Each pixel driving unit includes a driving transistor and a driving control module. A gate electrode of the driving transistor is connected to the driving control module, a first electrode thereof receives a first power voltage, and a second electrode thereof is connected to the driving control module and a light-emitting element. The driving control module is connected to a data line, a gate line, and the gate electrode and the second electrode of the driving transistor, and controls a potential at the gate electrode of the driving transistor in accordance with a data voltage applied to the data line under control of a gate driving signal from the gate line, so as to turn on/off the driving transistor.
