Abstract

The invention provides a touch panel. The touch panel comprises a circuit board, a first substrate for carrying the circuit board, a second substrate for carrying a plurality of keys and a plurality of key trigger parts. The second substrate comprises a plurality of contacts arranged facing the circuit board, and each of the contacts corresponds to an operable part and a key trigger part. Each key trigger part comprises a trigger layer, an insulating layer and a sensing layer which are arranged orderly; the trigger layer is arranged on and electrically connected with the circuit board. When one operable part is pressed by an object, the second substrate in the corresponding position is compressed downwards so that the corresponding contact moves downwards to contact with the corresponding key trigger part to generate a key trigger signal. When an object comes into contact with the surface of one key, the sensing layer of the corresponding key trigger part senses the approach of the object and generates a corresponding sensing signal. With the touch panel, the user can touch the surfaces of the keys so that the sensing layers generate corresponding trigger signals and press down the keys to trigger the corresponding trigger parts to generate the trigger signals; in addition, inconvenient operation of a specific operation action is also prevented.

Description

Touch panel

Technical field

The present invention relates to touch input field, relate in particular to a kind of touch panel with button.

Background technology

Along with the develop rapidly of mechanics of communication, the application of touch-screen is more and more general.Key-press input mainly comprises mechanical key and the large class of touch-screen two at present.Wherein, the advantage of mechanical key is that reliability is higher, and operating handle is good; Shortcoming is while using as information terminal, uses inconvenience when click, inquiry, browsing page.Touch-screen is just the opposite compared with mechanical key, easy to use when its advantage is click, inquiry, browsing page, uses inconvenience but carry out routine when input, and feel is poor when operation.Although touch-screen product has carried out certain improvement from software, for example, increase vibration feedback, keypad sounds etc., but input not as good as mechanical key in operating handle and routine.Existing input equipment, as telepilot, because great majority all adopt the mechanical key of traditional type, makes user use inconvenience clicking, when the operation such as inquiry.

Summary of the invention

In view of this, be necessary to provide a kind of touch panel with button, use mechanical key separately and make user's unhandy technical matters in the time carrying out specific operation action to solve input equipment of the prior art.

The invention provides a kind of touch panel, comprise circuit board and for carrying the first substrate of this circuit board, this touch panel also comprises:

Second substrate, for carry multiple can operating portion, this second substrate comprises multiple contacts, be arranged at this second substrate in the face of this circuit board one side, and each contact is corresponding with a button.

Multiple button trigger units, each button trigger unit is corresponding with a contact, and each button trigger unit comprises trigger layer, insulation course and inductive layer, and this trigger layer is arranged on this circuit board, and be electrically connected with this circuit board, this insulation course is arranged between this trigger layer and this inductive layer.When this trigger layer is touched contact for the button of sensing correspondence position, produce corresponding induced signal.Can be to the second substrate of lower compression correspondence position in the time that an object is pressed a button, be arranged on contact on correspondence position thereupon moving downward with corresponding button trigger unit contact, further trigger corresponding trigger layer and produce button trigger pip.

With respect to prior art, touch panel provided by the invention, by forming inductive layer on button trigger unit surface, and arranges button on touch panel surface with button trigger unit accordingly, user can make corresponding inductive layer produce trigger pip by touch key-press surface, realizes common touch function.User triggers corresponding button trigger unit by pressing keys and produces trigger pip, gives user to press the sensation of mechanical key, thereby has solved user's unhandy technical matters in the time carrying out specific operation action.

Embodiment

Below in conjunction with accompanying drawing, the present invention is described in further detail.

Refer to Fig. 1, the touch panel 10 in an embodiment of the present invention comprise first substrate 11, second substrate 12, circuit board 13, multiple button trigger unit 14 and multiple can operating portion 15.Wherein, this first substrate 11 is for bearer circuit plate 13, on this second substrate 12, arrange the plurality of can operating portion 15.Multiple button trigger units 14 are arranged on circuit board 13, and each button trigger unit 14 be arranged on second substrate 12 one can operating portion 15 position corresponding.In the present embodiment, this second substrate 12 is made up of elastomeric material, the plurality of can being made up of plastic resin material by operating portion 15.

Each button trigger unit 14 comprises trigger layer 140, insulation course 141 and inductive layer 142, and wherein, this trigger layer 140 is arranged on circuit board 13, and itself and this circuit board 13 is electrically connected, and this insulation course 141 is arranged between trigger layer 140 and inductive layer 142.In the present embodiment, this insulation course 141 is made up of tygon (polyethylene, PE) membraneous material.

This inductive layer 142 is formed at the surface of button trigger unit 14, and this inductive layer 142 is for when object contact one button surperficial, sense object with the contacting of button, produce corresponding induced signal.In the present embodiment, this inductive layer 142 is sprayed at the surface of insulation course 141 by ag material.

On this second substrate 12, a side of face circuit board 13 also arranges multiple contacts 120, these 120 positions, each contact respectively be arranged on this second substrate 12 one can operating portion 15 position corresponding.When pressing one can operating portion 15 time, second substrate 12 correspondence positions are bent downwardly owing to being pressed, conflicting with corresponding button trigger unit 14 thereupon moving downward in the contact 120 being arranged on second substrate 12 correspondence positions, makes trigger layer 140 produce button trigger pip.Thereby what be pressed can produce button trigger pip by triggering corresponding trigger layer 140 by operating portion 15.

Thereby in the time that user touches a button, first inductive layer 142 produces induced signal, when user presses this button until when the trigger layer 140 of this button trigger unit 14 of conflicting, trigger layer 140 further produces button trigger pip.

Use above-mentioned touch panel, by forming inductive layer on button trigger unit surface, and with button trigger unit, button being set accordingly on touch panel surface, user can make corresponding inductive layer produce trigger pip by touch key-press surface, realizes common touch function.User triggers corresponding button trigger unit by pressing keys and produces trigger pip, gives user to press the sensation of mechanical key, thereby has solved user's unhandy technical matters in the time carrying out specific operation action.

Be understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change the protection domain that all should belong to the claims in the present invention with distortion.
