China Patent Publication No.：105045421A, publication date：2015-11-11, discloses a kind of touch-screen, comprising：Touch
Control chip and some lines of induction；Touch chip is used for the touch scanning signal that high frequency is sequentially output to some lines of induction；Should
Touch-screen also includes：Heating module, the heating module is added by being superimposed DC voltage on each line of induction to touch-screen
Heat.Embodiment of the present invention in terms of existing technologies, adds heating module on the touchscreen, the heating module by
DC voltage is superimposed on each line of induction, touch-screen is heated, so as to lift the temperature of touch-screen, this way is that is, favourable
There is steam in avoiding touch-screen because of excessive temperature differentials (such as environment temperature is much larger than the temperature of screen surface), lift the experience of user
Sense；It can be effectively prevented from causing touch-screen thickness to increase because separately adding one layer of zone of heating in touch-screen and influenceing Consumer's Experience again
The problem of.Still there is button in this technical scheme and display screen is provided separately, and there is interval between such button and panel, so
Structure the problem of can be made troubles to product.
Utility model content

IC is connected with MCU, the front covering matcoveredn of the substrate, and the one side of the protective layer and contact of going with is etched with several
Each described button is corresponding with a button figure on button figure, substrate.Touch-screen on substrate by setting button
And display device, display screen and button are packaged together so that its compact conformation, improve properties of product；Plated on substrate
Upper metal key-press, button and substrate are realized no matter it is all an entirety to see or seen outside protective layer inside protective layer
Real integrative-structure, simplifies the structure of button, has saved cost.
Preferably, the position of the protective layer correspondence display screen is protective clear layer.
Preferably, the capacitance touch IC is arranged on the substrate.
Preferably, described substrate is plastic base, the button is the button that fine silver or pure chromium make.This practicality is new
Type is in use, when finger is close to the button of corresponding pattern, touching IC just can detect the capacitance variations between finger and button, MCU
Corresponding operation is made according to the change of electric capacity, and corresponding content is shown on screen.
Preferably, the display device is LED light, digital screen or LCDs.
The substantial effect of utility model is：Touch-screen on substrate by setting button and display device, by display screen
It is packaged together with button so that its compact conformation, improves properties of product；Metal key-press, button and base are plated on substrate
Plate realizes real integrative-structure, simplified no matter it is all an entirety to see or seen outside protective layer inside protective layer
The structure of button, has saved cost.The utility model is in use, when finger is close to the button of corresponding pattern, touching IC and just can
The capacitance variations between finger and button are detected, MCU makes corresponding operation according to the change of electric capacity, and corresponding content is existed
Shown on screen.
