However, in the using process of the user, microcracks at the edge of the glass substrate in the terminal area easily cause crack expansion, so that a great amount of screen splash and other defects occur in the using process of the end user.
At present, the method for detecting the microcracks in the terminal area of the display panel generally comprises the steps of firstly detaching the backlight module and then detecting the edge of the glass substrate in the terminal area by using an optical microscope. But because the backlight unit who tears down has great probability unable used repeatedly, causes the material waste easily.
