It needs to control full frame, simulates the touch operation of arbitrary point, then conductive module can be subjected to uniform layout.Such as Fig. 3 institute
Show, is a kind of this specification conductive module schematic layout pattern shown according to an exemplary embodiment.In this embodiment, appoint with
Electronic equipment be smart phone for, in order to be adapted to more great the small screen, the panel of larger size, the uniform cloth of panel can be configured
The distance of full conductive module and adjacent conductive intermodule is within a preset range.Panel and touch screen upper left angle alignment are pasted
It closes, then it can be according to information acquisitions conductive module and screens such as location information of the conductive module on panel and screen sizes
The corresponding relationship of location information.
It is understood that can also be laid out according to demand using other placement strategies to conductive module, herein not
It repeats one by one.
Various technical characteristics in embodiment of above can be arbitrarily combined, as long as the combination between feature is not present
Conflict or contradiction, but as space is limited, it is not described one by one, therefore the various technical characteristics in above embodiment is any
It is combined the range for also belonging to this disclosure.
It is illustrated below with one of which combination.
