Preferably, the shading strip of a plurality of intersection, two two-phase of shading strip interval are provided with above the upper reflectance coating
Adjacent just luminous light emitting source.It is provided with shading strip between per two adjacent keys, can avoid the light beam phase of adjacent key
Mutually influence.
Preferably, the lower end surface of the upper reflectance coating, the upper surface of lower reflectance coating are respectively provided with structure in curved surface.On guaranteeing
Transmitting film downwards and emit around and lower reflectance coating can by light upwards and emit around so that the range that light is reflected
It is wider.
Preferably, the light guide plate uses transparent acrylic resin, and the light guide plate upper surface is provided with multiple grooves,
The arc-shaped shape of groove, and its inner wall is curved-surface structure, so that the range of light diffusion is wider.
Preferably, just luminous light emitting source side and surface is arranged in the upper reflectance coating, and the light guide plate setting exists
The just other side of luminous light emitting source.So that the light beam that just luminous light emitting source is issued from top and around is spread to side.
Wherein, light beam can preferably can be reflexed to the light guide plate of side by the upper arc-shaped shape of reflectance coating, the reflectance coating of arc shape
On.
Preferably, the light beam issued from top and around in addition to just luminous light emitting source is spread to side, can also set
It sets in just luminous light emitting source from top and the light beam issued around is spread around.Realize the structure of this function are as follows: institute
The surface that just luminous light emitting source is arranged in reflectance coating is stated, the light guide plate is located at the surrounding of just luminous light emitting source.
Preferably, the substrate is using any one in PET, FPC, BT.
