Patent number: 7980750Abstract: A backlight assembly includes a lamp assembly, a receiving container and a panel guiding frame. The lamp assembly includes a light source to generate light and a lamp cover to reflect the light. The receiving container includes a bottom and a sidewall. The sidewall includes a first sidewall portion facing the lamp cover and separated from the lamp cover by a first interval and a second sidewall portion separated from the lamp cover by a second interval narrower than the first interval. The panel guiding frame includes a first frame portion facing an end of the bottom and a second frame portion extended from the first frame portion along a side face of the second sidewall and having an opening corresponding to the first sidewall portion. Thus, the backlight assembly may have a reduced non-effective display area.Type: GrantFiled: June 2, 2009Date of Patent: July 19, 2011Assignee: Samsung Electronics Co., Ltd.Inventors: Jin-Soo Shin, Jeoung-Gwen Lee

Patent number: 7959344Abstract: In a backlight assembly and a display device having the same, a receiving container includes a bottom plate and sidewalls adjacent to the edges of the bottom plate. A molded frame includes a first plate surrounding the sidewalls and a second plate connected to a side of the first plate. A second plate is substantially parallel with the bottom plate. A lamp assembly includes a lamp cover received in the receiving container and a lamp received in the lamp cover. An optical module is interposed between the molded frame and the receiving container to improve optical characteristics of a light generated from the lamp. A fixing member is combined with fixing portions of the receiving container, the molded frame and the lamp assembly to fix the receiving container, the lamp cover and the molded frame to one another. As a result, the manufacturing process can be simplified and mechanical strength improved.Type: GrantFiled: December 10, 2009Date of Patent: June 14, 2011Assignee: Samsung Electronics Co., Ltd.Inventor: Jin-Soo Shin
