Title:
METHOD AND DEVICE FOR DETECTING DRIVE CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2018/095036
Kind Code:
A1
Abstract:
A method and device for detecting a drive circuit. The method comprises: respectively inputting a data signal Data, a gate line scanning signal GS1, a voltage signal V, and a first control signal S of a first level to a data input end Data, a gate scanning input end G1, a power supply end Vdd and a sensing voltage end Sen of a drive circuit (100); by inputting a second control signal GS2 of a second level to a sensing scanning input end Sen of the drive circuit (100), controlling a pixel storage capacitor Cst of the drive circuit (100) so that same is charged, and measuring a first voltage V1 at an anode end ITO of an organic light-emitting diode (OLED) of the drive circuit (100); by inputting a second control signal GS2 of a third level to the sensing scanning input end Sen, controlling the pixel storage capacitor Cst so that same is discharged, and measuring a second voltage V2 at the anode end ITO of the OLED of the drive circuit (100); and determining whether the drive circuit (100) is abnormal according to the first voltage V1 and the second voltage V2.
