Further, described key switch layer is transparent membrane switch.
Further, described key switch layer is self-capacitance transparent push switch
Further, described key switch layer is mutual capacitance type transparent push switch.
Compared with prior art, this utility model provides band display backlight and touching of display backlight separated regions control show
Integrally key switch, by panel layer is connected to the upper end of key switch layer, key switch layer is connected to liquid crystal display layer
Upper end, and panel layer, button and liquid crystal display layer be that printing opacity shape is arranged, liquid crystal display layer can be that button and panel provide the back of the body
For the key switch that light, the content shown through liquid crystal display layer needs, and display area are bigger, liquid crystal display layer is from entirety
Lower section divergent rays upward so that the uniform light of whole key switch, structure is the simplest, and integrated level is higher, totally makes
Lower with cost, and display backlight can be with subregion control.
Accompanying drawing explanation
Fig. 1 is band display backlight and the tactile aobvious one of display backlight separated regions control of this utility model embodiment offer
The cutting structural representation of key switch.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
Below in conjunction with specific embodiment, realization of the present utility model is described in detail.
With reference to Fig. 1, the preferred embodiment provided for this utility model.
Band display backlight and touching of display backlight separated regions control that the present embodiment provides show one key switch, including
Panel layer 10, key switch layer 20 and the liquid crystal display layer 30 being sequentially connected with, wherein, panel layer 10 is connected to key switch layer
The upper end of 20, key switch layer 20 is connected to the upper end of liquid crystal display layer 30, and key switch layer 20 is provided with several buttons, liquid
Brilliant display layer 30 is provided with several align with button button viewing areas arranged, therefore, this display backlight separated regions control
Make, and panel layer 10, button and liquid crystal display layer 30 are arranged in printing opacity shape.
What above-mentioned band display backlight and display backlight separated regions controlled touches aobvious one key switch, by by panel layer
10 upper ends being connected to key switch layer 20, key switch layer 20 is connected to the upper end of liquid crystal display layer 30, and panel layer 10, presses
Key and liquid crystal display layer 30 are arranged in printing opacity shape, and liquid crystal display layer 30 can be button and panel offer backlight, through liquid crystal
For display layer 30 needs the content of display, and the display bigger key switch of area, liquid crystal display layer 30 is from overall lower section
Divergent rays upward so that the uniform light of whole key switch, structure is the simplest, and integrated level is higher, overall use cost
