Description
The application is dividing an application of patented claim of the same name (application number 03108495.8) submitted on April 14th, 2003.
Technical field
The present invention relates to a kind of capacitive touch control plate, particularly a kind of capacitive touch control plate that has combined button and handwriting functions.
Background technology
Trackpad be widely known by the people and be widely used in electronic product, Trackpad provides a kind of simple, light and cheap indicating device, the Trackpad that for example is applied to notebook computer provides mouse function.Fig. 5 is the principle of operation synoptic diagram of capacitive touch control plate, and it comprises insulcrete (not shown), ground plate 36, Y direction circuit 38, the X-direction circuit 40 of the superiors, and the three is connected to control circuit 46.Between Y direction circuit 38 and ground plate 36, equivalent capacity 42 is arranged, between x direction of principal axis circuit 40 and ground plate 36, equivalent capacity 44 is arranged.When finger or conductor when touching panel, control circuit 46 can be judged the touch location of finger or conductor according to changes in capacitance, and further does suitable processing.
Known Trackpad has three kinds of resistance-type, electromagnetic type and condenser types, and capacitance type touch control screen has been applied to public telephone or the guide system that for example can surf the Net, yet does not have hand-write input function.Resistance type touch control screen has been applied to for example PDA(Personal Digital Assistant) or electronic dictionary, but can't import according to touching of user's finger.Present Tablet PC or e-schoolbag or the like all dispose the Trackpad that has combined handwriting recognition and button input function, but are resistance-type or electromagnetic type as the one of which.Exert pressure in the set of contacts that need crash during the resistor type touch control plate operation, the electromagnetic touch-control plate then need use a kind of input pen that battery is housed to import.
With regard to performance and cost, capacitive touch control plate has obviously surpassed resistance-type and electromagnetic touch-control plate.The principle of work of capacitive touch control plate is to be utilized in user's finger or the capacity effect that moment produced that conductor touches Trackpad, thereby can confirm the position of finger or conductor according to the variation of capacitance.Therefore, capacitive touch control plate must be by means of the input pen of consumed power unlike electromagnetic touch-control plate that kind, and uses capacitive touch control plate also unlike using resistor type touch control plate that kind to need concentrated exerting pressure, so its serviceable life is longer.Moreover the composition of capacitive touch control plate is simple, and element is few, and yield rate is high, makes that cost was lower when capacitive touch control plate was produced in a large number.
Can know that by above-mentioned explanation capacitive touch control plate obviously has more advantage,, the input interface that another kind of cost is lower, use is more convenient can be provided if can capacitive touch control plate and for example keyboard and input function such as hand-written be used in combination.
Summary of the invention
One of the object of the invention has been to provide a kind of capacitive touch control plate that has combined button and handwriting functions.
According to the present invention; A kind of capacitive touch control plate that has combined button and handwriting functions; Multiple modes of operation such as button, handwriting input or mouse can be provided, and the panel of this Trackpad is divided into a plurality of zones, shows on it and a corresponding a plurality of pattern of the operator scheme that provides; Comprise mode selector switch in these patterns, it is used for select operating mode.Under the button pattern, these patterns have comprised the button pattern of simulating keyboard.Under handwriting input mode, these zones have comprised the handwriting recognition zone that is used for handwriting input.Under mouse mode, these zones comprise cursor zone of action and level, vertical scrolling zone.
