BACK FRAME, MANUFACTURING METHOD OF THE BACK FRAME, AND BACKLIGHT SYSTEM

摘要

A back frame of a flat panel display device, a method for manufacturing the back frame, and a backlight system comprising the back frame. The back frame (23) of the flat panel display device (20) comprises at least two main splicing pieces (261, 262, 281, 282, 283, 231, 232, 233, 234, 61, 62, 63, 64) connected to each other in a splicing manner. The at least two main splicing pieces (261, 262, 281, 282, 283, 231, 232, 233, 234, 61, 62, 63, 64) comprises a main splicing piece (261, 262, 281, 282, 283, 231, 232, 233, 234, 61, 62, 63, 64) for bearing a light source (65, 67). A heat dissipation fin group (611, 711) is arranged on the main splicing piece (261, 262, 281, 282, 283, 231, 232, 233, 234, 61, 62, 63, 64) for bearing the light source (65, 67). In the back frame (23) of the flat panel display device (20), the mold structure is simple, the mold cost of the back frame (23) is reduced, and the material of the back frame (23) is saved to reduce the production cost of the flat panel display device (20), and meanwhile, the back frame (23) is beneficial to heat dissipation of the light source (65, 67).
