Background

Referring to fig. 1 and 2, in the liquid crystal display module, when the backlight FPC 2 needs to be welded to the main FPC 1, the welding position of the backlight FPC 2 and the main PFC needs to be protected by attaching the insulating tape 3, and the main FPC 1 and the backlight FPC 2 need to be bent and then attached to the back of the display module by the double-sided tape 4 disposed on the back of the main FPC 1, in the prior art, the position of the double-sided tape 4 overlaps with the welding position of the main FPC 1 and the backlight FPC 2, so that the following problems may occur: the parts overlapped at the position comprise a backlight FPC 2, a main FPC 1, soldering tin height, double-sided adhesive tape 4, insulating adhesive and the like, the thickness is generally thicker, and the requirement on the structure of the whole machine (the whole machine needs to avoid the position) is higher; after the welding is performed, the adhesion of the double-sided tape 4 may be affected due to the high temperature.

Accordingly, the prior art is deficient and needs improvement.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provides a liquid crystal display module.

The technical scheme of the utility model is as follows: the utility model provides a liquid crystal display module, comprising: the module body, the module body includes FPC and main FPC in a poor light, the FPC welding that is shaded is in main FPC's front, be equipped with the cover on the main FPC the insulating cement of FPC and main FPC welding position is shaded, the insulating cement surpasses main FPC's appearance certain length, main FPC's the back is equipped with the double faced adhesive tape, the double faced adhesive tape corresponds keeps away the sky backlight FPC and main FPC's welding position works as main FPC and the FPC buckle the setting of being shaded are in when the module body back, the double faced adhesive tape is connected the back of module body with main FPC, the insulating cement tape stretches out the part of main FPC appearance is attached in the back of display module body.

Further, the certain length is 2 mm to 7 mm.

Preferably, the certain length is 4 mm.

Furthermore, the double faced adhesive tape correspondingly keeps away any two of the backlight FPC, the main FPC and the insulating adhesive tape from having overlapped positions.

Furthermore, the main FPC is provided with an alignment silk-screen printing device for aligning the joint margin adhesive paper.

By adopting the scheme, the utility model has the beneficial effects that: the double-sided adhesive tape keeps away the position where the backlight FPC and the main FPC are welded, so that the thickness of the position of the bent main FPC can be reduced, too much space of a subsequent complete machine is not occupied, and the subsequent complete machine design and the space arrangement of components are facilitated; the problems of softening of double-sided adhesive tape and the like during welding are avoided, and the pasting quality and the bonding effect are improved; through being used for pasting the back of main FPC and display module body with the extension of insulated adhesive tape, can promote and paste fixed effect, avoid main FPC to rise to stick up.

Detailed Description

The utility model is described in detail below with reference to the figures and the specific embodiments.

Referring to fig. 3 to fig. 5, in the present embodiment, the present invention provides a liquid crystal display module, including: the module body, the module body includes FPC 20 and main FPC 10 in a poor light, FPC 20 welding in a poor light is in the front of main FPC 10, be equipped with the cover on the main FPC 10 the insulating adhesive tape 30 of FPC 20 in a poor light and main FPC 10 splice site, insulating adhesive tape 30 surpasses the appearance certain length of main FPC 10, the back of main FPC 10 is equipped with double faced adhesive tape 40, double faced adhesive tape 40 corresponds the clearance of keeping away the splice site of FPC 20 in a poor light and main FPC 10 works as main FPC 10 is in with FPC 20 in a poor light buckle and is set up when the module body back, double faced adhesive tape 40 connects the back of module body with main FPC 10, insulating adhesive tape 30 stretches out the part of main FPC 10 appearance is attached at the back of display module body.

Further, the certain length may be 2 mm to 7 mm, and in this embodiment, 4 mm.

Further, in this embodiment, the double-sided adhesive tape 40 corresponds to a position where any two of the backlight FPC 20, the main FPC 10, and the insulating adhesive tape 30 are overlapped, and the double-sided adhesive tape 40 corresponds to a position where the backlight FPC 20 is overlapped with the main FPC 10, a position where the backlight FPC 20 is overlapped with the insulating adhesive tape 30, and a position where the main FPC 10 is overlapped with the insulating adhesive tape 30, which are not only the welding positions of the backlight FPC 20 and the main FPC 10, but also the thickness of the bent position can be further reduced.
