Detailed description of the invention
In order to be more clearly understood from the technical characteristic of the present invention, purpose and effect, now comparison accompanying drawing is detailed
Describe the detailed description of the invention of the bright present invention in detail.
Fig. 2 is the schematic diagram of the bendable printed circuit board (PCB) of one embodiment of the invention.Refer to Fig. 2, this
The bendable printed circuit board (PCB) 200 of embodiment have multiple first connection pad 210, multiple second connection pad 220 with
Multiple 3rd connection pads 230.First connection pad 210 engages the first port 312 of the first assembly 310, and second connects
Second port 322 of pad 220 joint the second assembly 320, the 3rd connection pad 230 engages the 3rd assembly 330
3rd port 332.From the foregoing, the bendable printed circuit board (PCB) 200 of the present embodiment provides three kinds and connects
Pad 210,220 and 230, therefore can be used for connecting three kinds of assemblies 310,320,330.Consequently, it is possible to only
Single bendable printed circuit board (PCB) 200 is wanted just to may replace two bendable printed circuit board (PCB)s of prior art,
The most with low cost, it is possible to alleviate the weight of whole module, also reduce simultaneously and connect the number of times of processing procedure and contract
Short processing time, also can promote assembling yield.
In the present embodiment, first connection pad the 210, second connection pad 220 and the 3rd connection pad 230 are with general institute
As a example by the kenel of the golden finger claimed, that is its width is more than the All other routes on bendable printed circuit board (PCB) 200
The width of (not illustrating), to promote the yield connected.Additionally, first connection pad 210 of the present embodiment and
Two connection pads 220 line up same string.Therefore, the first connection pad 210 be suitable for being connected with the second connection pad 220 line up with
First port 312 and the second port 322 of string.It addition, the bendable printed circuit board (PCB) 200 of the present embodiment
There is a breach 202.Breach 202 separates the first connection pad 210 and the second connection pad 220.By breach 202
Design, can increase the first connection pad 210 and the second connection pad 220 relative between the degree of freedom moved, to carry
High respectively with the first port 312 and convenience of the second port 322, the most also can increase this connection pad region can
The bending ability of bending.Furthermore, first connection pad the 210, second connection pad 220 and the 3rd connection pad of the present embodiment
230 edges being all located at bendable printed circuit board (PCB) 200, the bendable printed circuit board (PCB) 200 being so designed that
It is relatively easy to and with low cost on making.Otherwise, if connection pad is produced at non-edge, not only make relatively
For difficulty, follow-up difficulty when being connected with other assembly is the highest.Additionally, bendable printed circuit board (PCB)
May also set up chip 240 and passive component 250 on 200, the present invention is not intended to its quantity.
Fig. 3 is the schematic diagram of the touch control display module of one embodiment of the invention.Refer to Fig. 3, this enforcement
The touch control display module 50 of example include display floater 310, contact panel 320, drive circuit board 330 and
The bendable printed circuit board (PCB) 200 of Fig. 2.In other words, the present embodiment is by first assembly 310 of Fig. 2,
Second assembly 320 and the 3rd assembly 330 are defined to display floater 310, contact panel 320 respectively and drive
Circuit board 330, but the bendable printed circuit board (PCB) 200 of Fig. 2 can also be used for connecting other kinds of assembly.
Display floater 310 has the first port 312.Contact panel 320 is stacked and placed on display floater 310, and tool
There is the second port 322.Drive circuit board 330 has the 3rd port 332.Bendable printed circuit board (PCB) 200
The first connection pad 210 engage the first port 312 of display floater 310, the second connection pad 220 engages touch surface
Second port 322 of plate 320, the 3rd port 332 of the 3rd connection pad 230 bonding drive circuit board 330.
As long as consequently, it is possible to single bendable printed circuit board (PCB) 200 just may replace prior art two are bendable
Printed circuit board (PCB), the most with low cost, it is possible to alleviate the weight of whole touch control display module 50, also simultaneously
Decrease and connect the number of times of processing procedure and shorten processing time, also can promote assembling yield.
In the present embodiment, above-mentioned display floater 310 is liquid crystal panel.Additionally, display floater 310
The second port 322 of the first port 312 and contact panel 320 the connecing of multiple connection pad may be simply distributed
Closing district, the 3rd port 332 of drive circuit board 330 is then probably an adapter of possessive volume, but
The present invention is not limited to this.For example, the first port 312 of display floater 310 refers to display floater
The marginal distribution of the glass substrate of 310 has the region of multiple connection pad, and these connection pads can be with anisotropic conductive
Or other modes engage the first connection pad 210 of bendable printed circuit board (PCB) 200.The second of contact panel 320
Port 322 refers to that the marginal distribution of the flexible base plate of contact panel 320 has a region of multiple connection pad, and these
Connection pad can engage the second connection pad of bendable printed circuit board (PCB) 200 with anisotropic conductive or other modes
220.3rd port 332 of drive circuit board 330 can be welded to the connection on drive circuit board 330
Device, is made up of insulating body and the metal terminal that is embedded in insulating body.It addition, from direct-view display surface
The direction viewing of plate 310, the first port 312 of the display floater 310 of the present embodiment and contact panel 320
The position of the second port 322 stagger, be therefore easy to connect with the first of bendable printed circuit board (PCB) 200
Pad 210 engages with the second connection pad 220.
In sum, in the bendable printed circuit board (PCB) and touch control display module of the present invention, bendable printing
Circuit board provides three kinds of connection pads.Therefore, as long as using the single bendable printed circuit board (PCB) just can be by touch-control
Panel and display floater are connected to drive circuit board respectively.So, a bendable printed circuit has been saved
The cost of plate and weight, decrease the number of times of connection and can shorten processing time improving product yield.
Above in conjunction with accompanying drawing, embodiments of the invention are described, but the invention is not limited in above-mentioned
Detailed description of the invention, above-mentioned detailed description of the invention is only schematic rather than restrictive, this
The those of ordinary skill in field, under the enlightenment of the present invention, is being protected without departing from present inventive concept and claim
Under the ambit protected, it may also be made that a lot of form, within these belong to the protection of the present invention.
