CN103744826A - Lead touch film circuit board and layout technology with software no longer distinguishing base and side - Google Patents

Abstract

The invention discloses a lead touch film circuit board and layout technology with software no longer distinguishing base and side. The layout technology includes changing a distribution mode in which a lead is connected with an FPC (flexible printed circuit), namely two original different layout modes for base and side, into a same layout mode shared by base and side. Complexity of the software is lowered, maintenance cost is reduced, and uniform product delivery ability is improved.

Description

A kind of wire touch control film circuit board and software are no longer distinguished the topology of base and side

Technical field

The invention belongs to electronic technology, field of nanometer material technology.

Background technology

Along with universal at smart mobile phone end and panel computer of touch technology, the mankind have formed the custom of touch-control, and touch technology is just progressively to large scale future development, and two kinds of main flow large touch technology are commercial.

Copper conductor (or other plain conductors) printing technology take Japan as representative, another is silver particles (or other conduction metallicss) printing technique.These technology have a common ground, using metallics as raw material, and extremely low resistance, superfine wire, reaches nanoscale, and human eye almost be can't see.

Touch control film can touch area on, transverse axis and the longitudinal axis are distributing and are detecting the wire of finger touch, wire is finally connected to circuit board by FPC, take Fig. 1 as example, side layout, laterally, for long limit, has 36 wires as detecting device, be longitudinally minor face, FPC whipping, longitudinally, has 20 wires.The distribution mode that wire is connected to FPC is: 18, top, to detect laterally, and 20, middle part, detects longitudinally, and 18 of bottoms are detected laterally, just corresponding this distribution mode of the data that software layer obtains.Fig. 2 is base layout, can see that FPC whipping is in long edge position, and same whipping mode has just become 10, top tracerse survey minor face, the long limit of 36, middle part tracerse survey, 10 of bottoms tracerse survey minor face.In conjunction with Fig. 1 and Fig. 2, we can find, two kinds of layouts of base and side, need to select at software layer (or managing in hardware circuit board), just can be them from gathering the Data Integration processing coming up, because the distribution mode of the data that side collects is 18-20-18, and the distribution mode of the data that base collects is 10-36-10.The code (or needing the touch control film that user obtains according to oneself to select on software) that need to manage like this two cover software and hardwares, this has increased the complexity of product.

Summary of the invention

For problem above, a solution has been proposed, no matter this scheme makes base or side layout, the distribution pattern that they are connected to FPC is living, this makes software and hardware drive code no longer to need to distinguish the difference of touch control film, shield the difference of bottom, greatly simplified management process, also increased user's experience.

No matter be the layout of base or the layout of side, on cabling, long limit (36 wire detector), the unified FPC upper end that is connected to, minor face (20 wire detector), the unified FPC lower end that is connected to, the data that circuit board collects like this for the distribution pattern of 36-20, are no longer distinguished base or the layout of side without exception.

Realization is in conjunction with special process: comprise nm-class conducting wire, and copper conductor, the micro wirings such as silver-colored wire are as sensor, in conjunction with printing technique, printing technology and other wire laying technologies.

  

Accompanying drawing explanation

Fig. 1 is side layout, and the distribution pattern that wire is connected to FPC is 18-20-18, and middle 20 wires detect minor face, above 18 add 18 of top and bottom, 36 wires detect long limits altogether.

Fig. 2 is base layout, and the distribution pattern that wire is connected to FPC is 10-36-10, and middle 36 wires detect long limit, above 10 add 10 of top and bottom, 20 wires detect minor faces altogether.

  

In the protection domain of spirit of the present invention and claim, any modification and change that the present invention is made, all fall into protection scope of the present invention.

  

Claims (4)

1. wire touch control film circuit board and software are no longer distinguished a topology of base and side, wire are connected to the layout pattern of FPC, by original base and side two, overlap different layout patterns, change base and side into and share same set of layout pattern.

2. wire touch control film circuit board and software are no longer distinguished Side and Base layout.

3. be not limited to 56 tunnel sensor placements, the sensor placement that the present invention comprises any way.

4. the present invention is contained in the combination of special process: comprise nm-class conducting wire, and copper conductor, the micro wirings such as silver-colored wire are as sensor, in conjunction with printing technique, printing technology and other wire laying technologies.
