Accompanying drawing explanation
Fig. 1 is the stratiform decomposition texture schematic diagram of the embodiment of the present invention.
Detailed description of the invention
With detailed description of the invention, the present invention is described in further details below in conjunction with the accompanying drawings.
As it is shown in figure 1, the present invention includes backlight 1, transparent ground 2, the preferred LED of backlight 1
And it is positioned at the back side of ground 2.Clean oil it is coated with successively in the front (upper surface of Fig. 1) of ground 2
Enamelled coating 3, prime coat 4, intermediate primer layers 5, top coat layer 6.
Specifically, clean oil enamelled coating 3 is painted the paint such as preferably blue, and it is sprayed at ground 2
Front.Its color is the most unrestricted, though using the colored colored varnish, but specifically what color, take
Certainly in the color of product requirement.Before spraying, in being painted, mixing adds clean oil, after preventing
In phase operation, during laser laser carving, penetrate this layer, calcination ground 2.
Prime coat 4, the Main Function of intermediate primer layers 5 are shading, prevent the light of backlight 1 from bottom
Divulging out, owing to black paint and silvery white colored paint have stronger shaded effect, (i.e. black paint has stronger
Shaded effect, silvery white colored paint can reduce finish paint aberration), therefore prime coat 4 is preferably black, spraying
Region outside key label on clean oil enamelled coating 3, intermediate primer layers is then preferably silvery white, its spraying
Region outside key label on prime coat 4.
Color of paint used by top coat layer 6 is preferably identical with the color of paint of clean oil enamelled coating 3, top coat layer
6 is also preferably blue paint, and it is sprayed on intermediate primer layers 5 region outside key label.Due to face
The color of paint of enamelled coating 5 is identical with the color of paint of clean oil enamelled coating 3, such as, be blueness, therefore may be used
Cleaner and tidier with the color that is button, more glittering and translucent.Certainly, the color of top coat layer 6 does not the most limit,
Actual color is with product demand, such as: white, green, powder etc..Color of paint used by top coat layer 6 is also
Can be different from the color of paint of clean oil enamelled coating 3, by the combination of different colors, button can be made
Abundant color is had to represent.
It is emphasized that four layers are uniformly sprayed paint and can obtain prominent technique effect, such as: light-proofness
By force, it is not required that the region of light leak never light leak；Color will not have aberration, and what color of surface requirements is with regard to energy
Color is required expected from reaching.
For the key label of formation the present embodiment simple, efficient, the present embodiment have employed when being formed
