Abstract
The invention discloses a touch control identifying method, wherein a touch control screen related to the touch control identifying method comprises a distance sensing layer and a signal processor which is electrically connected with the distance sensing layer; the distance sensing layer senses capacitance change caused by an external object; the signal processor receives a capacitance change signal of the distance sensing layer and judges the position of a touch control point according to the capacitance change of the distance sensing layer, thus preventing contact between fingers and the touch control screen, wherein no fingerprint is left on the touch control screen to influence the definition of the touch control screen, and the operation is simple and convenient.
Description
Technical field
The present invention relates to a kind of touch-control recognition methods of touch screen, especially a kind of touch-control recognition methods that need not to touch touch screen.
Background technology
Along with science and technology development, touch screen has replaced the mechanical type push button panel gradually becomes the new operation interfaces of electronic equipment such as mobile phone, notebook.Touch screen comprises resistance type touch control screen, capacitance type touch control screen, and they obtain coordinate by different modes.Existing resistance type touch control screen or capacitance type touch control screen all need can collect touch signal by finger with contacting just of touch screen, and then judge the touch location of finger.For a long time, can shorten the serviceable life of touch screen, and after touching touch screen, touch screen all can stay finger mark at every turn, influences the sharpness of touch screen to the pushing of touch screen.So be necessary to provide a kind of need not directly to contact, just can discern the method for touch information with touch screen.
Summary of the invention
Technical matters to be solved by this invention provides a kind of touch-control recognition methods that need not to touch touch screen.
In order to address the above problem, the invention provides a kind of touch-control recognition methods, the related touch screen of described touch-control recognition methods comprise every empty inductive layer and with the signal processor that is electrically connected every empty inductive layer, the described capacitance variations that causes every empty inductive layer induction exterior object; Described signal processor receives described every empty inductive layer capacitance variations signal, and judges the touch point position according to described every empty inductive layer capacitance variations.
Compared with prior art, the method every the blank operation touch screen of the present invention can avoid pointing with touch screen between contact, do not stay finger mark on the touch screen again, influence the sharpness of touch screen, and simple to operation.
Description of drawings
Fig. 1 is the method block diagram of the present invention every the blank operation touch screen.
Fig. 2 is that the present invention singly refers to the method block diagram every the blank operation touch screen.
Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Please in conjunction with Fig. 1 and Fig. 2, the related touch screen of touch-control recognition methods of the present invention comprise every empty inductive layer and with the signal processor that is electrically connected every empty inductive layer, the described capacitance variations that can responsive perception exterior object causes every empty inductive layer, described exterior object can be that finger or other can cause every the pointer of empty inductive layer capacitance variations etc.Described signal processor receives described every empty inductive layer capacitance variations signal, and handles described signal, and described signal processor is judged the finger position according to described capacitance variations every empty inductive layer.Described change every empty inductive layer electric capacity is relevant with the position of exterior object, and described position every empty inductive layer capacitance variations maximum be exterior object with every the immediate position of empty inductive layer, just the user wants the position of the function items selected, and, reduce gradually every empty inductive layer changes in capacitance amount along with increasing gradually every empty inductive layer and finger distance; Described change every empty inductive layer electric capacity also relevant with the mobile alignment of exterior object, described position every empty inductive layer capacitance variations maximum corresponding to described exterior object move through every empty inductive layer relevant position.
Described touch-control recognition methods can refer to touch-control and refer to touch-control more by identification form.When the user singly refers to touch control operation to touch screen, user's finger moves closer to described touch screen, arrival is in the appreciable scope of empty inductive layer, the electric capacity every empty inductive layer of described touch screen changes, described position every empty inductive layer capacitance variations maximum be exterior object with every the immediate position of empty inductive layer, just the user wants the position of the function items selected, and along with increasing gradually every empty inductive layer and finger distance, reduce gradually every empty inductive layer changes in capacitance, signal processor receives every the capacitance variations signal of empty inductive layer and according to every empty inductive layer capacitance variations, judge user's finger position, promptly judge the function items that the user selects.When the user carries out referring to touch control operation to touch screen more, described mobile alignment every empty inductive layer finger sensing, mobile alignment according to finger, described electric capacity every empty inductive layer changes, and described every empty inductive layer capacitance variations maximum the position corresponding to described exterior object move through every empty inductive layer relevant position.Signal processor receives and handles the capacitance variations every empty inductive layer, judges the sky information of pointing out more.
The user can comprise that selection operation, page turn over operation and amplification dwindle etc. to the operation that touch screen carries out.When the user will carry out selection operation to touch screen, only need finger is pointed to function items to be selected, enter in the touch screen reconnaissance range but point, finger causes every empty inductive layer capacitance variations, signal processor receives and handles every empty inductive layer capacitance variations, finishes selection operation.When the user will carry out page turn over operation to touch screen, but a plurality of finger in the touch screen reconnaissance range and on the plane parallel with touch screen simultaneously left or move right, finish forward or page turn over operation backward.When the user will amplify reduction operation to touch screen, only need two fingers in the scope that touch screen can be detected, to carry out move toward one another or opposing motion, promptly two simultaneously close towards each other directions of finger slide or two fingers towards each other away from direction slide, finish touch screen amplified the operation of dwindling.
Compared with prior art, the method every the blank operation touch screen of the present invention can avoid pointing with touch screen between contact, do not stay finger mark on the touch screen again, influence the sharpness of touch screen, and simple to operation.
