Patent number: 8109667Abstract: A backlight module and a method for manufacturing a base thereof are provided. The backlight module base includes a back plate and a frame. The back plate has a plate body and at least one sidewall, which includes a wall body and a folding structure bending from the top of the wall body. The folding structure, the plate body, and the wall body together enclose a groove. The frame is formed on the plate body and adjacent to an inner surface of the sidewall. A part of the frame is embedded into the groove. The engagement between the frame and the groove increases the contact area between the frame and the back plate to improve the connection strength. In addition, the folding design of the sidewall increases the rigidity of the whole structure.Type: GrantFiled: February 27, 2009Date of Patent: February 7, 2012Assignee: AU Optronics CorporationInventors: Ping-Fu Wang, Wei-Chih Chen, Yung-Chih Liu

Patent number: 7404663Abstract: A backlight module is suitable for use in a liquid crystal display. The backlight module includes a back plate, and a lamp, over the back plate by a distance. The back plate has a hole under the lamp. The hole can be a hole under the lamp corresponding to an electrode of a high voltage end of the lamp. The hole or a certain number of the holes can be replaced by an indentation, which can also effectively increase the separation distance between the lamp and the back plate. Actually, the hole and the indentation can be used together to form a desired pattern corresponding to the lamp. The lamp can be a plurality of lamp.Type: GrantFiled: April 8, 2005Date of Patent: July 29, 2008Assignee: Hannstar Display CorporationInventors: Chi-Hao Chiu, Ping-Fu Wang
