Keyboard device and backlight module

Abstract

A keyboard device includes a light-emitting module, which comprises a body and a light-adjusting component. The body includes a light-emitting surface and a light-emitting unit, the light-emitting unit being used to generate primary light. The light-adjusting component is disposed on the light-emitting surface of the body and located in the light-emitting path of the light-emitting unit, to change the optical parameters of the primary light.

Claims

2. The backlight module of the keyboard device as claimed in claim 1, wherein the optical parameters include the color, angle, distribution of light, or a combination of at least two of them.

3. The backlight module of the keyboard device as described in claim 1, wherein the light adjustment element is a lens to change the emission angle of the original light.

4. The light-emitting module of the keyboard device as described in claim 3, wherein the lens is a condenser lens, a diffuser lens, a Fresnel lens, or a curved lens.

5. The backlight module of the keyboard device as described in claim 1, wherein the backlight unit includes a first light-emitting element, a second light-emitting element and a third light-emitting element, the first light-emitting element, the second light-emitting element and the third light-emitting element respectively emit a first color light, a second color light and a third color light to jointly constitute the original light, and the light adjustment element respectively changes the emission angle of the first color light, the second color light and the third color light.

6. The backlight module of the keyboard device as claimed in claim 1, wherein the light adjustment member has a light-emitting surface and the light-emitting surface has an optical microstructure.

7. The backlight module of the keyboard device as described in claim 6, wherein the optical microstructure includes a dot structure, a grating structure, a microlens array, or a combination of at least two thereof.

8. The backlight module of the keyboard device as claimed in claim 1, wherein the light adjustment element is made of an elastic material.

9. The backlight module of the keyboard device as claimed in claim 1, wherein the light adjustment element is made of a composite material comprising a light-transmitting substrate and a color material.

10. The backlight module of the keyboard device as claimed in claim 9, wherein the color material comprises an inorganic pigment, an organic pigment, a colorant, a colorant, or a combination of at least two of these.

11. The backlight module of the keyboard device as described in claim 9, wherein the backlight unit is a white light-emitting element and the original light is white light.

12. The backlight module of the keyboard device as claimed in claim 1, wherein the light adjustment element includes a lens, an optical film, or a combination thereof.

13. A keyboard device, comprising: One substrate; A keycap is mounted on this base plate; A light guide plate is stacked on top of the substrate; And a light-emitting module as described in any one of claims 1 to 12, wherein the light-emitting surface of the body of the light-emitting module faces the light guide plate.

14. The keyboard device as claimed in claim 13, wherein the light guide plate has a receiving groove in which the light-emitting module is disposed.

15. The keyboard device as claimed in claim 13, wherein the material of the light-adjusting element of the light-emitting module is the same as the material of the light guide plate.

16. A keyboard device, comprising: One substrate; A keycap is mounted on this base plate; And a light-emitting module as described in any one of claims 1 to 12, the light-emitting module being connected to the substrate, and the light-emitting surface of the body of the light-emitting module facing the keycap.

17. The keyboard device as claimed in claim 16 further includes a light-transmitting elastomer disposed between the keycap and the substrate, and the light-transmitting elastomer covers the light-emitting surface of the body of the light-emitting module.

18. The keyboard device as claimed in claim 17, wherein the light-transmitting elastomer is made of an elastic composite material comprising an elastic substrate and a coloring material.
