In the present embodiment, the aluminium foil 703 only cover in stent 701 with 702 corresponding region of button, i.e., only with
The region of button 702 carries out heat diffusion, same to reach well compared with the second face of stent 701 is completely covered in aluminium foil 703
Heat dissipation effect.
In the present embodiment, a small amount of LED708 can be used, as shown in fig. 7, in the present embodiment, only with a LED light
Bar, and the direction of LED light bar is corresponding with 701 shortest side of stent, so that, the caloric value of LED708 is further reduced, is avoided
The backlight function of keyboard is opened for a long time, is caused the rise of 702 temperature of button, is influenced the problem of user experience；Also, the stent
701 the second face is bonded successively with the nonmetal film, the light guide plate 704 and the aluminium foil 703, so that the branch
Frame 701 and the aluminium foil 703 close the LED708, the light seal of the keyboard further enhanced, avoid light leak from influencing to use
Experience at family.
