Title:
DETECTION METHOD AND DETECTION DEVICE FOR SCANNING DRIVE CIRCUIT, AND LIQUID CRYSTAL PANEL
Document Type and Number:
WIPO Patent Application WO/2017/000434
Kind Code:
A1
Abstract:
A detection method for a scanning drive circuit. The scanning drive circuit comprises a plurality of cascaded scanning drive units, and the detection method comprises: controlling a plurality of scanning drive units to provide in succession a scanning signal for a corresponding one of a plurality of scanning lines (S11); detecting a pulse signal sequence induced on at least one data line which intersects with and is capacitively coupled to the plurality of scanning lines (S12); and determining the position of a scanning drive unit where abnormality exists in the scanning drive circuit according to the pulse signal sequence (S13). The detection method can effectively detect the position of a scanning drive unit in which abnormality occurs in a scanning drive circuit.
