In the case of, various modifications and structural change can be carried out wherein, and these are within the scope of the equivalent of claim.
But when connection with figures is read together, construction of the invention and operating method, together with its additional purpose and excellent
Point, it will be got the best understanding from the description of specific examples below.
Brief description of the drawings
Fig. 1 is the diagram decomposition view according to the capacitive touch screen of the present invention；
Fig. 2 is the illustrated section figure for the capacitive touch screen redressed in non homogeneity into the LED of installation region；And
Fig. 3 is the diagrammatic elevational view of the household electrical appliance with capacitive touch screen.
Embodiment
Now in detail referring to the drawings and first especially Fig. 1, illustrated therein is the exploded view of capacitive touch screen 1.
Capacitive touch screen 1 serves as the control panel or forth screen of the touch operation of household electrical appliance, wherein household electrical appliance such as baking box, stove
Stove, refrigerator, washing machine, dryer, dish-washing machine, refrigerator, cooker etc..
Capacitive touch screen 1 is formed using the molded clear substrate 3 with front side (user side) 5 and rear side 7.Multiple recesses
9 form in the rear side 7 of substrate 3.One layer of ornamental screen printing figure 11 is disposed on the substrate 3 also, because substrate 3 is
Bright, it is visible in preceding (user) side 5.Figure 11 show through capacitive touch screen 1 it is available, will by household electrical appliance perform control
Function.
It is printing conductive trace plate 13 to be deployed in behind the layer of ornamental screen printing figure 11.Print conductive trace plate
13 provide the electric trace and connection for all components to be mounted.Be attached to printing conductive trace plate 13 is conductive adhesive
15, surface mounted component 17 or printed circuit board (PCB) (PCB) 19 are also affixed to thereon.Installation elements 17 securely of conductive adhesive 15
With the connection of the trace on PCB 19 and offer to printing conductive trace plate 13.
Multiple LED 21 reversely installed are arranged on via conductive adhesive 15 in the recess 9 of substrate 3.More specifically,
The LED 21 that non homogeneity is redressed to installation is preferably used.Never in chain of command before the use that non homogeneity is redressed to the LED 21 of installation
It is previously used in plate.The LED to be redressed to installation due to non homogeneity is expensive without common LED or not as flushing the LED reversely installed, because
This, except complexity, the cost of control panel also reduces.
Fig. 2 is shown to redress into the LED 21 of installation region by the cross-sectional view of control panel 1 in non homogeneity.Such as figure
Shown, substrate 3 has the recess (well) 9 of LED lens 23 formed wherein, for receiving LED21.LED 21 LED bases
Plate 25 it is non-flush configuration in via conductive adhesive 15 be joined to printing conductive trace layer 13.Via what is formed in substrate 3
Recess 9, LED 21 simple installation is possible and produces that tolerance is less notable, because being mounted flush against what is be not required.It is recessed
Portion 9 allows to redress non homogeneity to be put on substrate 3 to the LED 21 of installation, so as to eliminate to printed circuit board (PCB) or more expensive
The needs of LED encapsulated types.
In itself, redressed present invention teaches non homogeneity and utilize the printing conduction mark that electrical connection is provided to the LED 21 of installation
Installation of the line 13 directly on decorative print substrate 3,11.It will now be described integrated non-directly on decorative print substrate 3,11
The advantages of flushing the LED21 reversely installed.
First, the use of printing touch trace 13 eliminates and due to changing the air gap caused by machinery and manufacturing process
The problem of association.Therefore optical noise problem alleviates.
Secondly, Electrical and Electronic element is installed directly on printed decoration substrate 3,11,13 to eliminate to big printing electricity
The demand of road plate.This causes cost to reduce, reliability increase and robustness increase.
3rd, light emitting diode is installed directly on decorative substrate and eliminated to using additional light blocking and/or light path
By the needs of device.Therefore, optical noise substantially reduces, and production tolerance is hardly important, and optical noise reduces equipment by significantly simple
Change.
