Abstract
A frame structure and a grounding structure of a liquid crystal module are disclosed. The frame structure is adapted for fixedly securing a flexible printed circuit board and a control printed circuit board on the frame, wherein the flexible printed circuit board is electrically connected to a liquid crystal display panel and the control printed circuit board is electrically connected to the flexible printed circuit board. The grounding structure is adapted for fixedly securing a grounding copper foil on a metal bezel.
Claims25
A frame structure of a liquid crystal module, said frame structure being adapted for fixedly securing a flexible printed circuit board which is electrically connected to a liquid crystal display panel, said frame structure comprising:
- a plurality of fasteners, each fastener including:
- a first clip piece;
- a second clip piece arranged around said first clip piece;
- and
- a gap disposed between said first clip piece and said second clip piece.
A frame structure of a liquid crystal module, said frame structure being adapted for fixedly securing a control printed circuit board which is electrically connected to a flexible printed circuit board, said frame structure comprising:
- a recess having a first edge, a second edge, a third edge and a fourth edge, said recess comprising:
- a slot on said first edge of said recess, for receiving said control printed circuit board;
- a plurality of protrusions on said second edge, said third edge and said fourth edge of said recess, for fixing said control printed circuit board in said recess;
- and
- a plurality of resilient engaging pieces disposed at said third edge, which is opposite to said first edge, of said recess for engaging with said control printed circuit board.
A frame structure of a liquid crystal module, said frame structure being adapted for fixedly securing a flexible printed circuit board which is electrically connected to a liquid crystal display panel, and for fixedly securing a control printed circuit board which is electrically connected to said flexible printed circuit board, said structure comprising:
- a plurality of fasteners, each fastener including:
- a first clip piece;
- a second clip piece arranged around said first clip piece;
- and
- a gap disposed between said first clip piece and said second clip piece;
- and
- a recess having a first edge, a second edge, a third edge and a fourth edge, said recess comprising:
- a slot on said first edge of said recess, for receiving said control printed circuit board;
- a plurality of protrusions on said second edge, said third edge and said fourth edge of said recess, for fixing said control printed circuit board in said recess;
- and
- a plurality of resilient engaging pieces disposed at said third edge, which is opposite to said first edge, of said recess for engaging with said control printed circuit board.
A grounding structure of a liquid crystal module, said grounding structure being adapted for protecting a control printed circuit board of said liquid crystal module from electromagnetic interference, said grounding structure comprising:
- a frame for receiving said control printed circuit board;
- a grounding conductive sheet, wherein one end of said grounding conductive sheet is electrically connected to said control printed circuit board, and the other end comprises a first engaging member;
- and
- a metal bezel for locking around said frame, said metal bezel including a second engaging member, wherein said second engaging member engages with said first engaging member.
A liquid crystal module, comprising:
- a first frame;
- a liquid crystal display panel consisting a liquid crystal layer between a pair of substrates;
- a back light module disposed beneath said liquid crystal display panel for providing a planar light;
- a second frame for supporting said back light module, said second frame assembling with said first frame to fixedly secure said liquid crystal display panel and said back light module;
- a flexible printed circuit board, wherein one end of said flexible printed circuit board is electrically connected to one of said substrates, and the other end is bent to be secured at back of said second frame;
- and
- a control printed circuit board, wherein one end of said control printed circuit board is electrically connected to said flexible printed circuit board,
- wherein said second frame comprises:
- a plurality of fasteners, each fastener including a first clip piece and a second clip piece opposite to said first clip piece, wherein a gap is disposed between said first clip piece and said second clip piece for fixedly securing said flexible printed circuit board therebetween;
- a recess disposed at said second frame for receiving said control printed circuit board;
- a slot disposed at a periphery of said recess for engaging against one end of said control printed circuit board;
- a plurality of protrusions disposed at said periphery of said recess for positioning said control printed circuit board;
- and
- a plurality of resilient engaging pieces for fixing said control printed circuit board.
