Embodiment

Below in conjunction with accompanying drawing content of the present utility model is described in detail.

With reference to Fig. 2, the utility model embodiment liquid crystal display module LCD encapsulating structure has been shown among Fig. 2, comprise polaroid 1 on, the described LCD2 that goes up polaroid 1 back side is close in one front, once polaroid 6, comprise that also one tightly clings the square shape black and white double faced adhesive tape 5 at the described LCD2 back side, this square shape black and white double faced adhesive tape 5 has the opening that a geomery and described down polaroid 6 are complementary, the described LCD2 back side and described square shape black and white double faced adhesive tape 5 openings that tightly cling the LCD2 back side constitute edge space in, described down polaroid 6 be bumped into described in the edge space, and described polaroid 6 fronts down are close to the residence and are stated the LCD2 back side.

The absolute value of described square shape black and white double faced adhesive tape 5 and the described difference of polaroid 6 thickness down is more than or equal to 0, and less than 0.2mm, wherein, described square shape black and white double faced adhesive tape 5 can be 0 with the described difference of polaroid 6 thickness down, Fig. 3 is edge form synoptic diagram in first kind of the utility model LCD encapsulating structure, here, the edge form comprises a LCD2 in first kind of this LCD encapsulating structure, once polaroid 61 and tightly clings the square shape double faced adhesive tape 51 at the described LCD2 back side, the described LCD2 back side and the described opening that tightly clings the square shape double faced adhesive tape 51 at the LCD2 back side constitute edge space in, described down polaroid 61 be bumped into described in the edge space, and described polaroid 61 fronts down are close to the residence and are stated the LCD2 back side.When if following polaroid 3 thickness of selected following polaroid 61 and existence in the market are identical, then have the thickness that as shown in Figure 3 internally-inlaid LCD encapsulating structure makes liquid crystal display module gross thickness reduce the used square shape black and white double faced adhesive tape 4 of 0.2mm(prior art and be generally 0.2mm).
