Module can use the touching box of touch screen, when touch screen is in PC mode and Android pattern switching, without switching touching box
Signal path, the touch screen after switch mode can be controlled.
By the above embodiment of the utility model, multiple devices to be controlled can receive touching box detection simultaneously
Touch signal, so that in touch screen switchover operation module without switching the signal path of touching box.But work as touch screen simultaneously
When having run multiple modules, multiple modules can receive touch signal, since the content of multiple modules operation is possible to different,
Therefore when touch screen has run multiple modules simultaneously, it may occur that control chaotic situation.
For example, touch screen runs on PC module still by taking the touch screen with PC module and Android module as an example, work as touch screen
When switching to Android module by PC module, if PC module does not have backstage out of service, and being only operate in touch screen, namely
Touch screen current display interface is the operation result of Android module, but PC module still runs on the backstage of touch screen, then user
It can also be received for the touch operation PC module of Android module, but since the touch operation that user is directed to Android module is adapted to
The operation of Android module is not particularly suited for PC module, therefore PC module will appear the chaotic situation of operation.
In order to solve this problem, the utility model above scheme additionally provides the controller communicated with fan out buffer,
Optionally, according to the utility model above-described embodiment, above system further include: controller 40 is communicated with fan out buffer, is used for
Control the output of fan out buffer.
Specifically, above controller can be MCU (Mcrocontroller Unit, micro-control unit).Controller can be with
It is controlled for the output to fan out buffer, thus after touching box receives touch signal, only to multiple devices to be controlled
The one or more of part send touch signal.
Optionally, according to the utility model above-described embodiment, controller, which is also used to control fan out buffer, to be stopped to be controlled
Device processed exports touch signal.
Still in the above-described embodiments, by taking touch screen runs on Android mode as an example, the channel of controller detection touch screen is cut
Instruction is changed, when touch screen detects the channel switching command of touch screen, controller control fan out buffer stops to Android mould
Block output, to avoid Android module while receive the touch signal of touching box, at this point, even if Android module be not turned off and
Backstage is run on, it will not be chaotic due to receiving the touching signals not being inconsistent.
