Abstract
A rolling apparatus, comprising a mounting bracket, a supporting platform and a rolling device; the mounting bracket is disposed above the supporting platform, and the rolling device is disposed on the mounting bracket so as to be located above the supporting platform; wherein the supporting platform is configured to support a display panel thereon; and the rolling device is configured to perform a rolling process on the display panel at a predetermined pressure. A rolling method, comprising supporting a display panel; and rolling the display panel at a predetermined pressure to cause an observable defection resulted from a foreign substance within the display panel. With the rolling apparatus and the rolling method, the display panel containing foreign substance will be detected as a defective product during the Cell Test so as not to enter the modular process, thereby avoiding any waste of module materials.
