Abstract
The utility model discloses a structure of a printed circuit board bonded with an adhesive layer of a liquid crystal display panel, which comprises the printed circuit board and the panel. The printed circuit board is connected with the panel through a flexible printed circuit. The printed circuit board is bonded with the flexible printed circuit by using adhesive at the position of a connecting finger on the printed circuit board. The adhesive layer is arranged on the printed circuit board and is bonded on the edge of the other side of the printed circuit board corresponding to the connecting finger. The flexible printed circuit is fixed on the printed circuit board through the adhesive layer. Since the adhesive layer is bonded on the printed circuit board to fix the flexible printed circuit onto the printed circuit board, the stress effect on the edge of the side of the connecting finger is reduced, the flexible printed circuit is prevented from being damaged, and the display abnormality of a product is reduced further.
Description
Technical field
The utility model relates to the liquid crystal display field, and the printed circuit board (PCB) (PCB) that is specifically related to a kind of display panels adds the structure of sticking adhesive layer.
Background technology
Display panels, generally connect panel (CELL) and printed circuit board (PCB) (PCB) by flexible printer circuit (FPC), golden finger position on printed circuit board (PCB) (PCB), utilize the glue material that printed circuit board (PCB) (PCB) and flexible printer circuit (FPC) is bonding, and add that chase is in order to fix this flexible printer circuit (FPC) and printed circuit board (PCB) (PCB).And in the thinning machine, flexible printer circuit (FPC) is horizontally placed on the printed circuit board (PCB) (PCB), has following situation: 1, printed circuit board (PCB) (PCB) need not to bend and is fixed in chase (no chase); 2, the flexible printer circuit (FPC) that is positioned on the panel (CELL) is shorter; 3, flexible printer circuit (FPC) prolongation is across on the printed circuit board (PCB) (PCB); 4, replace chase protection flexible printer circuit by the aluminium insulating trip, thereby cause protective medium weak.
Above situation causes that printed circuit board (PCB) (PCB) and flexible printer circuit (FPC) easily form certain angle after printed circuit board (PCB) (PWB) process operations, in transportation and assembling process, connect the flexible printer circuit (FPC) of panel (CELL) and printed circuit board (PCB) (PCB) and be subject to the bending effect owing to there is no support fixed structure, and cause flexible printer circuit (FPC) injured bad, and then cause the goods display abnormality, it is bad (as square to be commonly called as function, go out picture etc.), and because mechanics limit, can't overcome very that this is bad.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, provides a kind of printed circuit board (PCB) of display panels to add the structure of sticking adhesive layer.
The technical solution adopted in the utility model is: a kind of printed circuit board (PCB) of display panels adds the structure of sticking adhesive layer, comprise a printed circuit board (PCB) and a panel, described printed circuit board (PCB) is connected with panel by flexible printer circuit, golden finger position on this printed circuit board (PCB), utilize the glue material that this printed circuit board (PCB) and described flexible printer circuit is bonding, described printed circuit board (PCB) is provided with glue-line, glue-line is attached to the edge with the another side of corresponding this printed circuit board (PCB) of described golden finger, and described flexible printer circuit is fixed on this printed circuit board (PCB) by described glue-line.
When described flexible printer circuit was one, as preferably, described glue-line covered Far Left cabling and rightmost cabling on this flexible printer circuit, and described glue-line does not exceed a left side and the right both sides of this flexible printer circuit.
When described flexible printer circuit is two and two when above, as preferably, described glue-line covers leftmost cabling on the flexible printer circuit of the leftmost side, and glue-line does not exceed the left side of this flexible printer circuit; Rightmost cabling on the flexible printer circuit of the described glue-line covering rightmost side, and glue-line does not exceed the right of this flexible printer circuit.
As preferably, described glue-line width is 1/4-3/5 of a described printed circuit board width.
As preferably, the quantity of described glue-line is one or two.
As preferably, described flexible printer circuit covers more than 2/3 and the bonding printed circuit board (PCB) of this flexible printer circuit at least.
Because the flexible printer circuit bending place is by copper golden finger and protective layer (polyamides Asia amine; PI) handing-over constitutes; both soft durometer differences; so causing flexible printer circuit golden finger seam crossing circuit folding during bending hinders; and then influence goods and normally show; the utility model makes flexible printer circuit tightly be fixed on the printed circuit board (PCB) plate by adding sticking adhesive layer, and the flexible printer circuit golden finger can't be hindered by folding.
Beneficial effect: the utility model printed circuit board (PCB) adds sticking adhesive layer, and flexible printer circuit is fixed on the printed circuit board (PCB) plate, to reduce the effect of PWB side golden finger edge stress, prevents the flexible printer circuit damage, and then reduces the display abnormality of goods.
