Method for smear measurement of display device and device for smear measurement of display device

摘要

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.

1. A method for smear measurement of display device comprises the following steps:
A: A flash with a moving pattern and an unmovable scale is played in the display device; B: Smear extent of the moving pattern is judged in accordance with the scale number occupied by the smear in the flash; wherein in step B, a picture displayed on the display device is acquired by using an image acquisition device, wherein, said picture comprises a scale, a moving pattern and a smear thereof then the scale number occupied by the smear on the picture is read to judge the smear extent of said moving pattern; wherein said flash picture has multiple moving patterns with different moving speeds and scales for measuring smears of said different moving patterns; wherein said scale comprises: type marks corresponding to different moving speeds and scales corresponding to type marks, said flash picture has eight scales for measuring smears of the pictures with different moving speeds.
