Description
Technical field
The present invention relates to a kind of input media, particularly relate to a kind of integration electromagnetic type and capacitive sensing multiple spot input media.
Background technology
Depend on the contactant kind, for example user's finger, digital pen (digital pen) or time writer (stylus) etc., and the deciding means of contacting points position, for example contactant when operation close position or distance etc., touch-control or input technology are divided into capacitive sensing (resistive-type), condenser type (capacitive-type), electromagnetic type (electromagnetic-type) and infrared-type touch technologies such as (infrared-type).
But the capacitance touching control input technology is the inductive layer that comprises a store charge in the screen module.The inductor that is positioned at the touch control screen periphery applies electric field in the touch control screen surface, and forms an electric capacity.For example user's finger or electric installation for a passive type touch-control source are when contact touch control screen surface, touch-control source and will produce electric current between the inductor of touch control screen periphery.The current difference that the inductor of different touch control screen peripheries produces can be used for calculating the position that touch point is positioned at the touch control screen surface.Because the passive type touch control screen must could effectively operate with conductor, the operational effect of passive type touch control screen is unsatisfactory when using non-conductive device for example the user wears gloves or nonconductor pointer (stylus).For active electric capacity touch-control input technology, active member sends an excitation signal electric current to inductor from touch point when touch point is sensed the touch-control action, and therefore calculates the position that touch point is positioned at the touch control screen surface.

But electromagnetic type input at present, capacitance touching control input all have its relative merits in individual other field.For instance, the advantage of electromagnetic type input can accomplish to locate accurately, if directly do not click and can respond with hand or other contactant, must need specific time writer and just can operate.The advantage of capacitance touching control input is to carry out input operation with hand or any contactant, and can utilize gesture to change by the multipoint mode touch-control and carry out diversified operation, according to distinctive respective action, can produce multiple application.But the precision of multi-point touch is the matrix density that depends on the capacitive touch control elements, therefore can't accomplish to locate accurately.Therefore, if two kinds of input technologies can be integrated, can have two kinds of input mode advantages concurrently.For in conjunction with the accuracy of electromagnetic induction and the convenience of capacitive sensing, and because the touch control component of capacitive sensing needs in-plant induction, therefore general traditionally way is the top that the touch control component of capacitive sensing is produced on the electromagnetic induction loop.Yet the touch control component of capacitive sensing is produced on the electromagnetic induction loop, the touch control component that causes capacitive sensing is intercepted (Shielding) electromagnetic induction loop receive the electromagnetic wave that input media is launched or reflected, seriously reduced the accuracy of electromagnetic induction detecting.
This shows that above-mentioned existing integration electromagnetic type and capacitive sensing input media obviously still have inconvenience and defective, and demand urgently further being improved in structure and use.In order to solve the problem of above-mentioned existence, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.Therefore how to found a kind of integration electromagnetic type and capacitive sensing input media of new structure, real one of the current important research and development problem that belongs to, also becoming the current industry utmost point needs improved target.
