Abstract
Official abstract text for this publication.
The present invention discloses a method for smear measurement of display device and a device for smear measurement of display device which comprises the following steps: a flash with a moving pattern and an unmovable scale is played in the display device; the smear extent of the moving pattern is judged in accordance with the scale number occupied by the smear in the flash. The present invention plays a flash with a moving pattern and an unmovable scale in the display device and judges smear extent of the moving pattern in accordance with the scale number occupied by the smear in the flash, so that the smear can be quantified by scales and different scale numbers corresponding to different smear extents are formed, to accurately judge the smear extent by observing the scale number occupied by the smear, thereby effectively monitoring the product quality.
