In embodiment of the present invention, two regions are divided by the FPC in LCDs, one region is provided with chip and the device of LCDs, another region is provided with chip and the device of touch screen, ensure that the ground of LCDs and touch screen (compares employing adapter to connect on same FPC, epd now will greatly reduce), thus reducing electromagnetic interference, and then improve electromagnetic performance；Chip and the device of touch screen and LCDs are set by the zones of different on same FPC, reduce cost.

It should be noted that, in this article, term " includes ", " comprising " or its any other variant are intended to comprising of nonexcludability, so that include the process of a series of key element, method, article or device not only include those key elements, but also include other key elements being not expressly set out, or also include the key element intrinsic for this process, method, article or device.When there is no more restriction, statement " including ... " key element limited, it is not excluded that there is also other identical element in including the process of this key element, method, article or device.

The invention described above embodiment sequence number, just to describing, does not represent the quality of embodiment.

One of ordinary skill in the art will appreciate that all or part of step in said method can be carried out instruction related hardware (such as processor) by program and complete, described program can be stored in computer-readable recording medium, such as read only memory, disk or CD etc..Alternatively, all or part of step of above-described embodiment can also use one or more integrated circuit to realize.Correspondingly, each module/unit in above-described embodiment can adopt the form of hardware to realize, such as realize its corresponding function by integrated circuit, the form that can also adopt software function module realizes, for instance the program/instruction performing to be stored in memorizer by processor realizes its corresponding function.The present invention is not restricted to the combination of the hardware and software of any particular form.

These are only the preferred embodiment of the application; not thereby the scope of the claims of the application is limited; every equivalent structure utilizing present specification and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in the scope of patent protection of the application.
