Abstract:
1. A back frame of a flat panel display device, wherein: the back frame comprises primary assembling pieces, secondary assembling pieces, and a bracing piece for fixing a circuit board, the primary assembling pieces having a number of at least two, at least one of the primary assembling pieces having an end forming joint sections, the secondary assembling pieces being joined to the primary assembling pieces; the at least two primary assembling pieces are joined through corresponding joint sections thereof, at least one of the primary assembling pieces comprising a reinforcement structure formed on the joint sections thereof; and the bracing piece comprises a bracing body, a first suspension section, a first bearing section, and a first resilient bent section, the bracing body being mounted to the primary assembling pieces or the secondary assembling pieces or is mounted to both the primary assembling pieces and the secondary assembling pieces, the first suspension section extending from the bracing body toward one side of the bracing body, the first bearing section being spaced from the bracing body and extending from the first suspension section toward one side of the first suspension section, the bracing body being connected to a first end of the first suspension section, the first bearing section being connected to a second end of the first suspension section, the first end and the second end being two ends of the first suspension section which are opposite with each other, and the bracing body and the first bearing section being not arranged in one same surface, the first resilient bent section being located between the first bearing section and the bracing body and being bent from the first suspension section toward one side of the first suspension section, the first resilient bent section comprises a fixed end connected to the first suspension section and a free end far away from the first suspension section, the first bearing section and the first resilient bent section resiliently clamping a first side edge of the circuit board between the first bearing section and the free end of the first resilient bent section.
