Patent ID: 10215628

Abstract:
The present disclosure relates to an image calibrating method and device of a testing apparatus for thin film transistor (TFT) substrate. The method comprises following steps of: calculating an image offset value by using coordinate information of each pixel in a prescribed target image obtained by the testing apparatus for the thin film transistor substrate; and determining whether the offset value is smaller than a prescribed threshold value, in a case where the offset value is not smaller than the prescribed threshold value, adjusting the image by using the offset value and recalculating the offset value by using the coordinate information of each pixel in the adjusted image; in a case where the offset value is smaller than the prescribed threshold value, calibrating the image obtained by the testing apparatus for the thin film transistor substrate with the offset value as a calibrating value. The calibrating efficiency and calibrating accuracy of the testing method for the thin film transistor substrate are enhanced according to the present disclosure.
