Patent number: 7744265Abstract: A backlight assembly that does not use a bottom chassis is presented. The absence of bottom chassis reduces manufacturing cost, simplifies the assembly process, and facilitates heat dissipation. The backlight assembly includes a lamp, a light guide plate, a mold frame and a securing mold. The lamp unit includes a lamp that generates light and a lamp cover that partially encloses the lamp. The light guide plate receives the light from the lamp unit and guides the light toward the front of the backlight assembly. The mold frame receives the lamp unit and the light guide plate through an open portion. The securing mold is coupled to the lamp unit and combines with the mold frame to secure the first lamp unit. The backlight assembly relies on one mold frame to hold its components together.Type: GrantFiled: August 23, 2006Date of Patent: June 29, 2010Assignee: Samsung Electronics Co., Ltd.Inventors: Sang-Min Kang, Jeoung-Gwen Lee, Tae-Hyung Kim, Jun-Hee Son, Chang-Hoi Kim
