Description
Technical field
The present invention relates to a kind of capacitive touch control plate, particularly about a kind of capacitive touch control plate with physical button function.
Background technology
As shown in Figures 1 and 2, traditional push- button input device 100 and 200 is the voltage statuss that change the I/O end of integrated circuit 104 by application of force extruding button 102, whether be depressed to detect button 102, for example, input media 100 among Fig. 1 is not when button 102 is pressed, the current potential of I/O end is a high levle, after button 102 is depressed, the current potential of I/O end then transfers low level to, input media 200 among Fig. 2 is not when button 102 is pressed, the current potential of I/O end is a low level, and after button 102 was depressed, the current potential of I/O end then transferred high levle to.Whether this kind mode is depressed to judge button owing to be to change voltage status by the application of force, therefore except having the clear and definite advantage of operational motion, has also possessed the characteristic of low power consumption.
And along with development of technology, the volume of various electronic installations is more and more littler, mancarried device particularly, but touch-tone input media but can't dwindle because of the relation of button again, thereby become the obstacle that dwindles the electronic installation volume, therefore have the people propose a kind of than the more frivolous Trackpad of button as input media.Fig. 3 is the sectional view of known capacitive touch control plate 300, wherein panel 302 and base plate 306 are the I insulator, conductor layer 308 is first inductor, conductor layer 310 is second inductor, insulation course 304 is between conductor layer 308 and 310, with spaced conductors layer 308 and 310, insulation course 304 and conductor layer 308 and 310 can be considered as a capacitor, when finger 312 touching Trackpads 300, electric capacity on its touch position will change, thereby can learn finger 312 whether on Trackpad 300, with and position on Trackpad 300.The induction mode of relevant capacitive touch control plate can be with reference to United States Patent (USP) the 5th, 920, No. 309, more detailed explanation is arranged wherein.Because capacitive touch control plate 300 has high-resolution advantage, therefore be suitable as the input media of character calligraph.Yet capacitive touch control plate 300 is to utilize the mode of induction to operate, thus can't clear and definite operational motion be arranged as touch-tone input media, and also constantly scanning comes the position of finger sensing, so also comparatively power consumption.Though at present can be on Trackpad the virtual key function, must constantly scan equally and come finger sensing whether to touch virtual key.
Therefore, a kind of input media that has physical button and capacitive touch control plate advantage concurrently is to be the institute Ji.
Summary of the invention
The object of the present invention is to provide a kind of capacitive touch control plate with physical button function.
According to the present invention, but first conductor layer that a kind of capacitive touch control plate with physical button function comprises a soft deformation below the panel, but the insulation course of one second conductor layer and a soft deformation is between this first and second conductor layer, on this insulation course, offer at least one cavity, when pushing with this corresponding position, cavity, first conductor layer produces deformation and passes this cavity and is connected with second conductor layer, voltage on first or second conductor layer is changed, trigger default keypress function; Wherein, first or second conductor layer has an inductor.
Capacitive touch control plate of the present invention changes current potential just as physical button by the mode of pushing, and to judge whether to trigger keypress function, therefore has the advantage of capacitive touch control plate and physical button simultaneously concurrently.
