A grounding structure of a liquid crystal module is disclosed. The grounding structure is adapted for protecting a control printed circuit board of the liquid crystal module from electro-magnetic interference. In one embodiment, the grounding structure comprises: i) a frame configured to receive the control printed circuit board, ii) a grounding conductive sheet, wherein one end of the grounding conductive sheet is electrically connected to the control printed circuit board, and the other end comprises a first engaging member and iii) a metal bezel configured to lock around the frame, the metal bezel including a second engaging member, wherein the second engaging member engages with the first engaging member.

Grounding structure for a liquid crystal module

A liquid crystal module is disclosed. In one embodiment, the liquid crystal module includes a first frame and a second frame configured to support a back light module and configured to fixedly secure a liquid crystal display panel and the back light module together with the first frame. The second frame comprises: i) a plurality of fasteners, each fastener including a first clip piece and a second clip piece opposite to the first clip piece, wherein a gap is disposed between the first clip piece and the second clip piece configured to fixedly secure a flexible printed circuit board therebetween, ii) a recess configured to receive a control printed circuit board, iii) a slot disposed at a periphery of the recess and configured to engage against one end of the control printed circuit board, iv) a plurality of protrusions disposed at the periphery of the recess configured to position the control printed circuit board and v) a plurality of resilient engaging pieces configured to fix the control printed circuit board.

Liquid crystal module

A LCD module comprises a LCD cell, a back light module and a pair of fastening structure including the first frame and the second frame, both capable of joining one with the other. The first frame, which can support the back light module, has a first locking mechanism on its edge, and the second frame, which is around the side of the display area of the LCD cell, has a second locking mechanism adjacent to its edge. By the combination the first locking mechanism and the second locking mechanism, the LCD cell and the back light module can be fastened together.

Liquid crystal display module and fastening structure thereof

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.

Liquid crystal module comprising fasteners for flexible circuit board

A cutting method of a tap carrier package of a liquid crystal display. The cutting method cuts a film comprising a first straight layout along a predetermined direction on a wiring layer comprising a second straight layout along the predetermined direction and a oblique layout, the method comprises the following steps. First, a breach is formed by cutting a part of the first straight layout on the film. Finally, the film is fastened on the wiring layer. Thus, the remaining first straight layout is only connected to the straight layout and the oblique layout is exposed through the breach.
