BACK FRAME OF FLAT PANEL DISPLAY DEVICE, MANUFACTURING METHOD OF THE BACK FRAME, AND BACKLIGHT SYSTEM

摘要

A back frame (23) of a flat panel display device (20) comprises at least two main splicing pieces (261, 262). The at least two main splicing pieces (261, 262) comprise splicing portions (2611, 2621). The at least two main splicing pieces (261, 262) are spliced and fitted to each other through corresponding splicing portions (2611, 2621) to form a main frame (27) of the back frame (23). The splicing portions (2611, 2621) of the at least two main splicing pieces (261, 262) are provided with fool-proofing structures fitted to each other. Also provided are a manufacturing method of the back frame (23) and a backlight system (21). In the back frame (23) of the flat panel display device (20), the manufacturing method of the back frame (23), and the backlight system (21), the structure is simple, the mold cost of the back frame can be reduced, the material of the back frame (23) can be saved to reduce the cost of the flat panel display device (20), and the fool-proofing design can be satisfied, thereby further reducing the misoperation and improving the production efficiency.
