Abstract

A touch-type transparent keyboard includes a touch screen, a transparent plate, and a light module. The touch screen is located on the transparent plate. The light module is located at a side of the transparent plate. When the light from the light module shines on the key icons and the key icons are displayed.

Claims

1. A touch-type transparent keyboard, comprising:

a touch screen;

a transparent plate including a plurality of key icons; and

a light module;

wherein the touch screen is located on the transparent plate, the light module is located at a side of the transparent plate;

when the light from the light module shines on the key icons and the key icons are displayed.

2. The touch-type transparent keyboard as claimed in claim 1, wherein the transparent plate is made of transparent glass or transparent resin.

3. The touch-type transparent keyboard as claimed in claim 2, wherein the key icons are formed on the transparent plate by sandblasting or frosting.

4. The touch-type transparent keyboard as claimed in claim 3, wherein the light module includes a cover and a light source;

one side wall of the cover defines a receiving slot, and the light source is located in the receiving slot.

5. The touch-type transparent keyboard as claimed in claim 4, wherein the light source is light emitting diode or cold cathode fluorescent lamp.

6. The touch-type transparent keyboard as claimed in claim 4, wherein the transparent plate includes an top surface and two side surfaces;

the key icons are formed on the top surface, each side surface defines a latch groove.

7. The touch-type transparent keyboard as claimed in claim 6, wherein two latch posts are oppositely located in the receiving slot, each latch post is locked in one latch groove.

8. The touch-type transparent keyboard as claimed in claim 4, further including a support assembly located under the light module, wherein the support assembly includes a power circuit board and a control circuit board electronically connected to the power circuit board.

9. The touch-type transparent keyboard as claimed in claim 8, wherein the light source is electronically connected to the power circuit board, the touch screen is electronically connected to the control circuit board.

10. The touch-type transparent keyboard as claimed in claim 9, wherein the support assembly includes a sleeve, a holder, a latch component, and a switch actuator;
