One of olefin polymer, COP) substrate.
It should be understood that the thermal expansion coefficients due to flexible parent metal are high, and the thermal expansion coefficients of glass baseplate are low, because
During panel pad 11 carries out contraposition with board pads 21 and is bonded, the glass baseplate of liquid crystal display panel 10 is heated for this
Swell increment afterwards can be ignored, and the expansion that the flexible parent metal of flexible circuit board 20 occurs after being heated, so that circuit board welds
The contraposition of disk 21 and panel pad 11 influences the display effect of liquid crystal display there are offset.In the utility model embodiment
In, in order to make board pads 21 and 11 accurate contraposition of panel welding plate, design each board pads 21 of flexible circuit board 20
Spacing between width and adjacent two board pads 21, so as to improve the contraposition weight of board pads 21 Yu panel pad 11
It closes.
Also referring to Fig. 1 to Fig. 4, in a specific embodiment, the swell increment of the flexible parent metal of flexible circuit board 20 by
Spacing between the width of each board pads 21 and adjacent two board pads 21 is accumulated after expanded by heating to be caused.Example
Such as, it is assumed that the total quantity of the board pads 21 of flexible circuit board 20 is n, the total length of the welding section 201 of flexible circuit board 20
For L1, the total length of the welding section after 20 expanded by heating of flexible circuit board is L2.The expansion length of flexible circuit board 20 is Δ l=
L2-L1.The width of each board pads 21 are as follows: W=W0+ Δ w, wherein Δ w=W2-W1 or Δ w=Δ l/ (2 (n-
1)), W is expressed as the width after board pads 21 expand, W0It is expressed as the width before board pads 21 expand, W1 and W2 divide
Do not indicate that the correspondence width after adjacent two board pads 21 expand, Δ w are expressed as the change of the width of single board pads 21
Change value.
The spacing of adjacent two board pads 21 are as follows: D=D0+ Δ d, wherein Δ d=D2-D1 or Δ d=Δ l/ (2
(n-1)), D is expressed as the spacing after the expansion between adjacent two board pads 21, D0It is expressed as adjacent two board pads 21
Between expansion before spacing, D1 and D2 are respectively indicated positioned at any adjacent two-by-two of the side center line A1 of board pads 21
Correspondence spacing after expansion between board pads 21, Δ d are expressed as the change of the spacing between adjacent two board pads 21
Change value.
In a specific embodiment, when panel pad 11 and board pads 21 are aligned, panel pad 11 and circuit
Plate pad 21 is aligned, and is pressed and connected by conducting resinl between panel pad 11 and board pads 21.
Please together referring to Fig. 3 and Fig. 4, in liquid crystal display panel 10 with flexible circuit board 20 during fitting, liquid crystal
After showing that device 100 is heat-treated, welding section 101 is substantially uninflated namely each panel pad 11 welding section 101 position
Substantially do not shift, and after flexible circuit board 20 is heat-treated, the two sides of welding section 201 towards center line A2 expand and
So that towards the direction far from center line A2 certain deviation occurs for each board pads 21 in the position of former welding section 201.Due to
One center bonding pads 111 are located at the center of welding section 101, and the second center bonding pads 211 are located at the center of welding section 201,
To which the first center bonding pads 111 still are able to be aligned with the second center bonding pads 211, and stacking is bonded together.Further, since second
Second outer ring pad 212 of 211 two sides of center bonding pads is deviated from neutral conductor A2 towards far from neutral conductor A2, therefore by designing each electricity
The width of road plate pad 21 is gradually increased from the second center bonding pads 211 towards far from the second center bonding pads 211, and adjacent two circuit board
Spacing between pad 21 is gradually increased from the second center bonding pads 211 towards far from the second center bonding pads 211, so that the second outer lap welding
Disk 212 still is able to pressing connection with corresponding first outer ring pad 112, and the first outer ring pad 112 is perpendicular to welding section
101 projection is all fallen in 212 region of the second outer ring pad, so that the first outer ring pad 112 and the second outer lap welding
Disk 212 is overlapped connection always, so as to improve between panel pad 11 and board pads 21 there are offset and caused by welding
Dislocation, and then improve the fitting quality and display effect of liquid crystal display 100.
The liquid crystal display and flexible circuit board that the utility model embodiment provides, by being arranged in the flexible circuit
The width of the board pads at plate center is less than the board pads of two sides, so as to improve between panel pad and board pads
Dislocation is welded caused by there are offset, and then improves the fitting quality and display effect of liquid crystal display.
