Abstract
The utility model discloses a liquid crystal display screen with a flexible circuit board. The flexible circuit board comprises a front panel and a back panel, wherein a bonding adhesive layer is arranged on the welding contact surface on the front panel or the back panel. The length of a golden finger on the front panel is not the same with the length of a golden finger on the back panel, and the outer ends of the golden finger on the front panel and the golden finger on the back panel are aligned. The flexible printed circuit (FPC) welding of the liquid crystal display screen with the flexible circuit board is more reliable.
Description
Technical field
The utility model relates to a kind of LCDs that has flexible PCB.
Background technology
The LCDs that has flexible PCB, when FPC (flexible PCB is commonly called as soft board) welded, FPC was shifted easily, made bit comparison difficulty, caused solder shorts, and the welding of often need doing over again has increased the time of welding and the waste of material when doing over again.
Because during FPC, the golden finger bending is frequent in welding, the golden finger of the FPC that tends to fracture causes product bad.
The utility model content
The utility model technical matters to be solved provides a kind of LCDs that has flexible PCB, and this FPC that has the LCDs of flexible PCB welds more reliable, and yield rate is high.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
A kind of LCDs that has flexible PCB, flexible PCB comprises front plate and back panel, on the welding surface of contact on front plate or the back panel, is provided with bonding glue-line.
The length of the golden finger on the front plate and the length of the golden finger on the back panel are inequality, and the golden finger on the front plate aligns with the golden finger outer end on the back panel.
The thickness of bonding glue-line is 0.05mm, and the length of the golden finger on the front plate and the length of the golden finger on the back panel differ 0.5mm.
Beneficial effect:
The LCDs that has flexible PCB of the utility model, the welding surface of contact increases one deck adhesive glue, with fixing FPC, prevents the FPC displacement, makes welding successful more easily.
In addition, the welding golden finger adopts the design of staggering, and makes to prevent not frangible of FPC golden finger to cause damage of product because of welding.
Description of drawings
Fig. 1 is the Facad structure synoptic diagram that has the LCDs of flexible PCB;
Fig. 2 is the reverse side structural representation that has the LCDs of flexible PCB.
The bonding glue-line of label declaration: 1-, 2-front golden finger, 3-reverse side golden finger, the 4-LCDs, the 5-front plate, 6-back panel, h1 are front golden finger length, h2 is a reverse side golden finger length.(golden finger on the front plate is the front golden finger, and the golden finger on the back panel is the reverse side golden finger.)
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Embodiment 1:
Like Fig. 1-2, a kind of LCDs that has flexible PCB, flexible PCB comprises front plate and back panel, on the welding surface of contact on front plate or the back panel, is provided with bonding glue-line.The length of the golden finger on the front plate and the length of the golden finger on the back panel are inequality, and the golden finger on the front plate aligns with the golden finger outer end on the back panel.
The adhesive glue layer thickness is 0.05mm (also can be 0.03-0.07mm), and requirement simultaneously can be born high temperature.During welding, tear the protection sheet of adhesive glue, contraposition is fixed on weld to FPC after having got well, and just can weld then.
For the FPC design of staggering, referring to Fig. 1 and Fig. 2, front golden finger length h1 is 1.8mm, and reverse side golden finger length h2 is 2.3mm, the 0.5mm that just staggers, and the size that staggers also can be set between the 0.3-1.0mm.
In addition, need to prove,, can adopt the design of here stagger design and bonding glue-line as long as relate to the welding of FPC, such as the welding of source plate backlight (BL) with main screen FPC, the welding of touch-screen and main screen FPC, the welding of main screen FPC and cell phone mainboard.
Claims (3)
1. a LCDs that has flexible PCB is characterized in that, flexible PCB comprises front plate and back panel, on the welding surface of contact on front plate or the back panel, is provided with bonding glue-line.
2. the LCDs that has flexible PCB according to claim 1 is characterized in that, the length of the golden finger on the front plate and the length of the golden finger on the back panel are inequality, and the golden finger on the front plate aligns with the golden finger outer end on the back panel.
3. the LCDs that has flexible PCB according to claim 2 is characterized in that the thickness of bonding glue-line is 0.05mm, and the length of the golden finger on the front plate and the length of the golden finger on the back panel differ 0.5mm.
