Abstract
The utility model discloses a kind of LCM liquid crystal display die sets with high reliability FPC bending structures, including LCM liquid crystal displays and FPC, FPC main bodys include sequentially connected bonding pad, FPC single layers bent area and FPC bilayers area, the one end in FPC bilayers area is equipped with the golden finger being connect with mainboard, bonding pad is connect with LCM liquid crystal displays, bonding pad be rectangular laminated structure, bonding pad tool is there are one zigzag bottom edge, FPC single layers bent area is provided with several through-holes, and through-hole avoids circuit setting.LCM liquid crystal display die sets provided by the utility model with high reliability FPC bending structures, the setting on zigzag bottom edge, so that when FPC bendings, shearing force is not centered on a line, by the way that the elastic stress of FPC single layers bent area can be released effectively equipped with through-hole, ensure bending effect, the corrugated L-shaped connection end effectively suffered external force of dispersion, it avoids FPC from being broken, improves the reliability of entire LCM liquid crystal display die sets.
Description
Technical field
The utility model is related to liquid crystal display die set fields more particularly to a kind of with high reliability FPC bending structures
LCM liquid crystal display die sets.
Background technology
Existing LCM liquid crystal display die sets, FPC are connected by a bonding pad with LCM liquid crystal displays, bonding pad
Lower end is linear type, is easy, along this section of the lower end this edge edge line of interconnecting piece, to cause product bad when FPC is bent.It was installing
The bonding pad of Cheng Zhong, FPC are bent, and bonding pad bending at this time will produce rebound stress, after FPC bendings, it is easy to go out
Now the case where whole rebound, cause to produce bad.When FPC is under external force active force, FPC, which is easy to happen, to fracture, these are all deposited
In serious quality, the risk of reliability.
Utility model content
The purpose of this utility model is to provide a kind of LCM liquid crystal display die sets with high reliability FPC bending structures,
To achieve the goals above, the utility model provides the following technical solutions：
A kind of LCM liquid crystal display die sets with high reliability FPC bending structures, including LCM liquid crystal displays and FPC,
The FPC main bodys include sequentially connected bonding pad, FPC single layers bent area and FPC bilayers area, the one end in FPC bilayers area
Portion is equipped with the golden finger being connect with mainboard, and the bonding pad is connect with the LCM liquid crystal displays, and the bonding pad is rectangular
Laminated structure, for the bonding pad tool there are one zigzag bottom edge, FPC single layers bent area is provided with several through-holes, described logical
Avoid circuit setting in hole.
Further, it is L-shaped that FPC bilayers area, which is stretched out with the connection end of the golden finger, and the L-shaped connects end
Edge is waveform.
Further, the through-hole is 9, the through-hole equidistant interval distribution.
The setting of FPC single layers bent area can reduce the rebound stress generated the when of being bent at this, increase flexibility, it is ensured that
It will not rebound after module Product Assembly, the corrugated L-shaped connection end effectively suffered external force of dispersion avoids FPC from being broken,
The setting on zigzag bottom edge so that when FPC is bent, shearing force is not centered on a line, and is distributed across sawtooth
Shape edge is attached on a face in FPC bilayers area, thus buckle resistance can be good, and FPC can be released effectively by being equipped with through-hole
The elastic stress of single layer bent area ensures bending effect, without cause due to bent area elastic-restoring force is big and make FPC from
Position after bending is rebounded, and the reliability of entire LCM liquid crystal display die sets is improved.
Description of the drawings
Fig. 1 is the main structure diagram of the utility model FPC.
Label in attached drawing be：1-FPC bilayers area, 2-FPC single layers bent area, the bonding pads 3-, 4- through-holes, 5- golden fingers.
Specific implementation mode
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
In the description of the present invention, it should be understood that term "center", "upper", "lower", "front", "rear",
The orientation or position of the instructions such as "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside", " clockwise ", " counterclockwise "
Relationship is set based on attached orientation or positional relationship shown in FIG. 1, to be merely for convenience of describing the present invention and simplifying the description, and
It is not that the device of instruction or hint meaning or element must have a particular orientation, with specific azimuth configuration and operation, therefore
It should not be understood as limiting the present invention.
As shown in Figure 1, a kind of LCM liquid crystal display die sets with high reliability FPC bending structures, including LCM liquid crystals
Display screen and FPC, the FPC main bodys include sequentially connected bonding pad 3, FPC single layers bent area 2 and FPC bilayers area 1, FPC single layers
The setting of bent area 2 reduces the rebound stress generated when bending at this, increases flexibility, it is ensured that after module Product Assembly not
Can rebound, the one end in FPC bilayers area 1 is equipped with the golden finger 5 connect with mainboard, the stretching of FPC bilayers area 1 with it is described
The connection end of golden finger 5 is L-shaped, and the L-shaped connection end edge is waveform, and corrugated L-shaped connection end is effectively divided
Suffered external force is dissipated, avoids FPC from being broken, the bonding pad 3 is connect with the LCM liquid crystal displays, the bonding pad 3
For rectangular laminated structure, there are one zigzag bottom edge, the settings on zigzag bottom edge for the tool of the bonding pad 3 so that FPC is bent
When, shearing force is not centered on a line, and is distributed across the face that jagged edge is attached to FPC bilayers area 1
On, thus buckle resistance can be good, 2 equidistant interval of FPC single layers bent area is provided with 9 through-holes 4, and the through-hole 4 is avoided
Circuit is arranged, and by that can be released effectively the elastic stress of FPC single layers bent area 2 equipped with through-hole 4, guarantee bends effect, without
Can cause due to bent area elastic-restoring force is big and so that FPC rebounds from the position after bending, improve entire LCM liquid crystal display modes
The reliability of group.
Above example is only to illustrate the technical solution of the utility model, rather than its limitations；Although with reference to aforementioned reality
Example is applied the utility model is described in detail, it will be understood by those of ordinary skill in the art that；It still can be to preceding
The technical solution recorded in each embodiment is stated to modify or equivalent replacement of some of the technical features；And these
Modification or replacement, the spirit and model of various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution
It encloses.
