Embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1-2, a kind of novel liquid crystal display device, including LCDs 1, backlight module 2 and FPC 3, institute
State the top that LCDs 1 is located at backlight module 2, the FPC3 is drawn from LCDs 1 to for LCDs
Drive signal is provided.The backlight module 2 includes the backboard 21 with accommodation space, and the FPC3 bendings are fixed on backboard 21
The back side.In order that can be accurately positioned after FPC3 bendings, meet the required precision of product, it is as shown in Figure 3-4, described in the utility model
At least one positioning hole 31 is opened up on FPC3, correspondence position is provided with least one locating dowel 22 on backboard 21, fixed after FPC3 bendings
Position hole 31 and the plugged and fixed FPC3 of locating dowel 22.With in the prior art by position line come the precision that positions compared with, prior art
Positioning precision typically because FPC3 opens up positioning hole 31 precision of positioning hole 31 can be enable to reach in 0.3mm, the utility model
0.05mm, and because the locating dowel 22 on backboard 21 is with screens effect, and then location dimension precision is reached 0.1mm.
As a further improvement, the minimum thickness of the locating dowel 22 is not less than 1mm, to prevent locating dowel to be broken；It is described
The size of positioning hole 31 is more unilateral than the size of locating dowel 22 to be more than 0.1mm, in order to which locating dowel 22 is interted into positioning hole 31,
Such as while take up an official post one one points of the minimum distance in take up an official post one one points and locating dowel 22 of positioning hole should be greater than 0.1mm.
As a further improvement, the locating dowel 22 and positioning hole 31 are respectively two, and the positioning hole 31 is relative
FPC3 is symmetrically disposed on FPC3, can further increase the convenience of positioning.
