The arbitrary and all combination of the Listed Items of pass.
As shown in figure 1, to utilize the module map from the multi-screen synchronous contactor control device for holding characteristic.
It is a kind of using from the multi-screen synchronous contactor control device for holding characteristic, including control circuit 101, connector 104, from molar block
103 and mutual tolerance module 102.
It is described to be installed on simultaneously in the control circuit 101 from molar block 103 and the mutual tolerance module 102；The control
Circuit 101 is used to control main touch-screen and multiple from touch-screen；The control circuit 101 is installed in main touch-screen, the master
Touch-screen and multiple induction channels from touch-screen and driving channel multiplexing, from holding, signalling channel is separate；The master touches
Touch screen and multiple lines of induction and drives line from touch-screen between each two and oneself appearance line is connected by the connector 104.
In the present embodiment, one is comprised at least from appearance chip from molar block 103.
In the present embodiment, mutual tolerance module 102 comprises at least a mutual tolerance chip.
The main touch-screen is connected with main frame, and the main frame is used to control the main touch-screen and multiple from touch-screen.
It is connected only with main touch-screen with main frame, it becomes possible to realize the main touch-screen of a host computer control and multiple from touch-screen
Function.Meanwhile main touch-screen and main frame are only connected, therefore, main frame only needs one interface of offer to be connected with main touch-screen, nothing
Need excessive interface.Thus when controlling multiple touch-screens, the annexation between main frame and touch-screen can be simplified.
In the present embodiment, the induction line of reaching the standard grade in the main touch-screen forms mutual tolerance structure with offline driver circuit
Afterwards, it is drawn out in the control circuit 101.
Preferably, the mutual tolerance structure is drawn out in the control circuit 101 by elargol line.
Specifically, in the visible area of touch-screen, induction line of reaching the standard grade forms mutual tolerance structure with offline induction line, these
Mutual tolerance structure is drawn out in the control circuit 101 outside visible area by elargol line.In addition, the line of induction and drives line in touch-screen
Extend on the connector 104 of touch-screen, the line of induction and drives line in other touch-screens are then connected by connector 104.
If there have the line of induction, drives line to occur to be overlapping, come in overlapping region with insulator separation.
In the present embodiment, the line of induction of the main touch-screen, drives line by the connector 104 with it is multiple from touch
The line of induction of screen, drives line are corresponding to be connected.
Specifically, each touch-screen is correspondingly arranged on connector 104.
Fill up between the main touch-screen and multiple every two induction lines of reaching the standard grade from touch-screen and formed certainly from appearance signal
Hold signal wire.
Each the signal wire that holds certainly of touch-screen extends to the total appearance signal wire certainly of integrated one of visible area foreign exchange.Then connect
Onto control circuit 101,
It is described that from holding, signal wire is separate, equal is connected with described from molar block 103.
Particularly, it is all from hold signal wire with from be connected in molar block 103 from holding chip, and every from appearance signal
Line connection differs from the pin for holding chip.
As shown in Fig. 2 the connection schematic diagram for multi-screen synchronous contactor control device in one embodiment.
In the present embodiment, by taking three touch-screens as an example.
Wherein, control circuit 101 is installed in main touch-screen, is respectively provided with control circuit 101 from appearance chip and mutual tolerance
Chip is each at least one.The induction channels of three touch-screens and driving channel multiplexing, and it is separate to hold signalling channel certainly, every two
The line of induction and drives line and oneself appearance line between individual touch-screen are connected by connector 104.
Main touch-screen is connected by USB line with main frame.
Therefore, main frame can control three touch-screens by a USB interface, and control need to be only installed in main touch-screen
Circuit 101 can just complete the control function of three touch-screens.So as to effectively simplify the company between main frame and multiple touch-screens
Relation is connect, compared with traditional needs install control circuit 101 in each touch-screen, significantly reduces multi-screen synchronous touch-control dress
The cost put.
As shown in figure 3, the structural representation for main touch-screen.
In visible area, induction line of reaching the standard grade (Rx1, Rx2, R^3 ... Rxn) and offline driver circuit (Tx1, Tx2,
Tx3 ... Txn) form mutual tolerance structure.Mutual tolerance structure is drawn out in the control circuit 101 outside visible area by elargol line.In addition,
The line of induction and drives line can be extended on the connector 104 of main touch-screen, and then connect the line of induction and the driving of other touch-screens
Line.In the line of induction and driving line overlap, overlapping part is come with insulator separation.
Filled up between every two induction line of layer of reaching the standard grade from signal is held, all extended to from appearance signal outside visible area is converged into
One total appearance signal wire, and being connected with control circuit 101 certainly.Particularly, each touch-screen is independent from signal wire is held
, differed with from the pin held when chip is connected.
It is above-mentioned to utilize the multi-screen synchronous contactor control device from appearance characteristic by installing control circuit 101 in main touch-screen, and
Installed in control circuit 101 from molar block 103 and mutual tolerance module 102, while main touch-screen and multiple senses from touch-screen
Answer passage and driving channel multiplexing, signalling channel is separate from holding.Main touch-screen and multiple from touch-screen between each two
The line of induction and drives line and from hold line connected by the connector 104.Led therefore, it is possible to be controlled by control circuit 101
Touch-screen and multiple from touch-screen, avoids installing control circuit 101 in each touch-screen, is touched so as to reduce multi-screen synchronous
The cost of control.
As shown in figure 4, to utilize the multi-screen synchronous touch control method from appearance characteristic.
