Title:
GATE DRIVING CIRCUIT AND DETECTION METHOD THEREFOR, ARRAY SUBSTRATE, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/152553
Kind Code:
A1
Abstract:
A gate driving circuit and a detection method therefor, an array substrate, and a display device. The gate driving circuit comprises a plurality of cascaded gate driving units (1), access units (2), a first signal line (3), and a second signal line (4), each access unit (2) being connected respectively to the corresponding gate driving unit (1) and the gate driving unit (1) at the next stage of the corresponding gate driving unit (1), the access units (2) to which the gate driving units (1) at odd-numbered stages correspond being connected to the first signal line (3) such that the first signal line (3) detects, by means of the access units (2), the output signals of the gate driving units (1) at the odd-numbered stages; the access units (2) to which the gate driving units (1) at even-numbered stages correspond being connected to the second signal line (4) such that the second signal line (4) detects, by means of the access units (2), the output signals of the gate driving units (1) at the even-numbered stages. Whether a defect is present in the gate driving unit (1) at each stage can be determined just by connecting the first signal line (3) and the second signal line (4) respectively to an oscilloscope when the detection is performed, with simple operation and improved detection efficiency.
