Description

A kind of spliced capacitive touch screen
Technical field
The utility model relates to capacitive touch screen, especially relates to a kind of capacitive touch screen of multiple reduced size that adopts and is spliced to form the large size capacitive touch screen meeting demand.
Background technology
The use of current condenser type display touch apparatus is more and more extensive in the life, work of people, often need larger-size touch-screen for some specific occasions, such as indoor touch-control electronic blank, outdoor touch-control electronic advertisement etc. show the dimensional requirement of touch-screen often beyond 100 inch to condenser type.The manufacture method of existing large size capacitive display touch-screen is the capacitance plate adopting monoblock, its one side is inductive layer, another side is for driving layer, two-layer corresponding signalling channel wherein respectively carrys out FPC(pliability flexible cord plate corresponding to pressing), touch-control IC(integrated circuit is connected by the mode of direct (FPC and IC, at the same area, is aggregated into master control IC by FFC line or LVDS again after splicing and realizes touch-control) or indirect (being connected with patchcord FFC by card extender, connector)) to reach the function of touch.Wherein inductive layer and driving layer multiselect Film(conductive film material), fit one piece at outermost layer and strengthen cover-plate glass, make it to form protective seam.
Touch-screen is larger, the size of the material required is larger, therefore the producer often needs the equipment customized to carry out processing process, manufacturing cost height is caused not looked forward to, and in manufacture process also easily there is damage in many large-sized components and parts, such as because the base material of Film is PET(polyethylene terephthalate), easy injured, size is larger, the probability of injured is higher, and large scale touch-screen need carry out large-area laser-induced thermal etching to Film, to form the conducting wire meeting design, Film laser-induced thermal etching area is too large, easily there is short circuit, the situation of open circuit, when large-sized Film and the laminating of corresponding element device, occur that the bad probability such as foreign material, bubble, concave point is also high.Moreover the material of monoblock just needs integral replacing once go wrong, and the cost of operation and maintenance is high, and also needs higher expense in transportation.
Utility model content
The purpose of this utility model is to provide a kind of capacitive touch screen of multiple reduced size that adopts and is spliced to form the large size capacitive touch screen meeting demand.
The purpose of this utility model can be realized by following technical scheme: a kind of spliced capacitive touch screen, it is characterized in that: the capacitive touch screen unit 1 comprising two or more than two, touch-control pcb board (touch-control printed circuit board (PCB)) 2 and master control IC(integrated circuit) (not shown), wherein said touch-control pcb board is laid with consistent with capacitive touch screen unit 1 quantity, and separate IC region, each capacitive touch screen unit 1 is by its FPC(pliability flexible cord plate) winding displacement is communicated with an IC region of touch-control pcb board, and the IC region that each capacitive touch screen unit 1 is communicated with is separate, the each IC region of described PCB Trackpad is gathered to master control IC.
The spliced capacitive touch screen that the utility model provides, when people touches any capacitive touch screen unit, touch signal enters IC region corresponding to PCB Trackpad through each capacitive touch screen unit 1, PCB Trackpad by its each IC areas accept to inconsistent touch screen signal gather to master control IC and identify, finally unified input operation system, realizes touch operation.
The capacitive touch screen that the utility model provides adopts the capacitive touch screen of some reduced sizes to be spliced into large-sized capacitive touch screen, therefore directly utilize the capacitive touch screen of conventional device fabrication reduced size during fabrication, thus reduce manufacturing cost and difficulty.The connecting method of this capacitive touch screen is succinct, ensure the superperformance of spliced capacitive touch screen, when impact use is broken down in a certain region, only need change this block capacitive touch screen unit, and in transportation, may be split into the smaller capacitive formula touch-screen being convenient to packaging and movement, reduce expense.
Under the prerequisite that the size of single capacitive touch screen unit is fixing, splicing after institute become touch-screen size difference, required capacitive touch screen element number is then different, number is more, then the total data of the required process of master control IC is larger, therefore, on the basis of the above, master control IC described in the utility model is provided with the IC of more than or; To carry out layout master control IC according to concrete design, realize the total data that it processes each group of touch-control IC fast and efficiently, and by process after data feedback or assign touch-control IC.
Single capacitive touch screen unit defines the width of its circuit with human finger or pen control, line width in the touch screen unit that size is fixed is less, the quantity of screen body peripheral disposition circuit is more, to should the IC region of the capacitive touch screen unit data that need process more, therefore on the basis of the above, the single IC region of touch-control pcb board described in the utility model comprises the IC unit of more than or; So that the IC unit of the number of, lines layout suitable quantity according to single capacitive touch screen unit, to meet the demand of data processing process.
Touch operating area be according to LCM(LCD MODULE) viewing area determine, touch operation just can be carried out in region for showing, therefore the splicing gap between adjacent two capacitive touch screen unit on the touch effect of touch-screen without any impact, for adapting to existing LCM(LCD MODULE) technical merit, and avoid that the splicing gap of adjacent two capacitive touch screen unit is excessive affects overall appearance, on the basis of the above, the splicing gap between adjacent two capacitive touch screen unit described in the utility model is 5 ~ 10mm.
On the basis of the above, the FPC winding displacement end of single capacitive touch screen unit 1 described in the utility model is provided with web joint 3, and this web joint is by FFC(flexible flat cable) the 4 IC regions being communicated with PCB Trackpads.The length of FFC is not subject to process technology limit, and flexible, can yield to the setting of other component locations, make whole product have more reasonably layout.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Spliced capacitive touch screen shown in Fig. 1 is embodiment of the present utility model, it comprise in two or more than two capacitive touch screen unit 1(figure be shown as four pieces), touch-control pcb board (touch-control printed circuit board (PCB)) 2 and master control IC(integrated circuit) (not shown), splicing gap wherein between adjacent two capacitive touch screen unit is 5 ~ 10mm, touch-control pcb board is laid with consistent with capacitive touch screen unit 1 quantity, and separate IC region, each capacitive touch screen unit 1 is by its FPC(pliability flexible cord plate) winding displacement end is provided with web joint 3, this web joint is by FFC(flexible flat cable) the 4 IC regions being communicated with touch-control pcb boards, and the IC region that each capacitive touch screen unit 1 is communicated with is separate, the each IC region of PCB Trackpad is gathered to master control IC.Become the concrete size of capacitive touch screen according to institute after splicing, master control IC is provided with the IC of more than or, and size is larger, and the IC number of master control IC setting is more; Simultaneously according to the number of, lines of single capacitive touch screen unit, the single IC region of touch-control pcb board comprises the IC unit of more than or, and the circuit of single capacitive touch screen unit is more, and the IC unit that single IC region is arranged is more.
