Abstract
A stack of light guide plates is proposed. Each light guide plate includes a light guide plate body and an incident side, thickness of the incident side is more than thickness of the light guide plate body, two light guide plates are reversely arranged and laminated when the two light guide plates are processed, and then a plurality of a pair of laminated light guide plates are stacked. The present embodiment provides a method for processing light guide plates. Even though the thickness of the incident side or the wedged shape of the incident side changes, the method can be adopted. The stack of light guide plates remain neat and flat using the method. Because a batch of light guide plates are cut and polished using the method, the efficiency in processing light guide plates improves. In this way, utilization of the equipment improves as well.
