摘要:
A set of measurement voltages having different voltage values are subsequently inputted to a measurement voltage input terminal of the pixel driving circuit, a light emitting state of a light emitting device under each measurement voltage is detected, and it is determined whether a storage capacitor in the pixel driving circuit is normal based on the light emitting state of the light emitting device.
