8. Handling precautions
8-1 Mounting method
A panel of LCD module made by Dalian Eastern Display Co., Ltd. consists of
two thin glass plates with polarizers that easily get damaged.
And since the module is constructed and fixed by utilizing fitting holes in the
Printed Circuit Board (PCB), extreme care should be used when handling the
LCD modules.
