Electronic device
An electronic device includes a display module, a base and a keyboard module. The display module is pivoted on the base. The keyboard module is disposed on the base. The keyboard module has a plurality of keys. Each of the keys includes a main body and an imprinted structure. The main body has a top surface. The imprinted structure is disposed on the top surface of the main body and includes a light guiding portion and a light scattering portion. A light emitted by the display module illuminates the keyboard module. The light is guided towards a specific direction when the light passes through the light guiding portion, and the light is scattered in other directions when the light passes through the light scattering portion.
1. An electronic device comprising:
a display module;
a base on which the display module is pivoted; and
a keyboard module disposed on the base, wherein the keyboard module has a plurality of keys, and each of the keys comprises:
a main body with a top surface; and
an imprinted structure disposed on the top surface of the main body and comprising a light guiding portion and a light scattering portion, wherein a light emitted by the display module illuminates the keyboard module, the light is directed towards a specific direction when the light passes through the light guiding portion, and the light is scattered in other directions when the light passes through the light scattering portion.
2. The electronic device according to claim 1 , wherein there is an included angle between the specific direction and the top surface of the main body, and the included angle is approximately 45 degrees.
3. The electronic device according to claim 1 , wherein the light guiding portion of the imprinted structure has a first concave-convex structure, and the light scattering portion of the imprinted structure has a second concave-convex structure, wherein an arrangement density of the first concave-convex structure is lower than an arrangement density of the second concave-convex structure.
4. The electronic device according to claim 1 , wherein the light guiding portion of the imprinted structure has a first concave-convex structure, and the light scattering portion of the imprinted structure has a second concave-convex structure, wherein a thickness of the first concave-convex structure is larger than a thickness of the second concave-convex structure.
5. The electronic device according to claim 1 , wherein the light guiding portion has a first concave-convex structure, the first concave-convex structure has a plurality of protrusions, each of the protrusions has a top corner, and the top corner has an angle between 80 and 100 degrees.
6. The electronic device according to claim 1 , wherein each of the keys further includes a print layer disposed between the main body and the imprinted structure.
7. The electronic device according to claim 6 , wherein the print layer has a text symbol area, and the light guiding portion is disposed corresponding to the text symbol area.
8. The electronic device according to claim 6 , wherein the print layer has a non-text symbol area, and the light guiding portion is disposed corresponding to the non-text symbol area.
9. The electronic device according to claim 1 , wherein the imprinted structure is a transparent paint, and after the transparent paint is disposed on the main body, a mold imprints the paint to simultaneously form the light guiding portion and the light scattering portion.
10. The electronic device according to claim 1 , wherein a material of the imprinted structure is a heat cured resin, a radiation cured resin, or an electron beam cured resin.
