Patent 7566161 was granted and assigned to AU Optronics on July, 2009 by the United States Patent and Trademark Office.
A reflector in a backlight module comprises a reflection layer and an electrical conduction layer. The conducting is installed on one side of a reflection layer, and is connected to the ground of the system. Thereby, when the reflector is applied to an edge-type or a direct-type backlight module, by grounding the electrical conduction layer, normal operations of devices in the backlight module will not be affected by electromagnetic interference (EMI) or electrostatic discharge (ESD).
