ILLUMINATED KEYBOARD

摘要

An illuminated keyboard includes a key structure, a sensor board, a light source, a light guide plate, an adhesive layer, and a bottom plate. The sensor board includes a key wiring region for sensing a depressing action of the key structure and thereby generates a key signal. The light source is used for emitting a light beam to the light guide plate. The sensor board is made of a light-transmissible material. The sensor board is disposed over the light guide plate. At least one edge region of the sensor board is coated with a light-shading material or mixed with a light-shading material. Moreover, the at least one edge region of the sensor board is bent to enclose at least one edge of the light guide plate in order to prevent lateral light leakage of the illuminated keyboard.

主权项

1. An illuminated keyboard, comprising:
a key structure, wherein when said key structure is depressed, a key signal is correspondingly triggered; a sensor board comprising a key wiring region for sensing a depressing action of said key structure and thereby generates said key signal; a light source for emitting a light beam; and a light guide plate located at a side of said light source for transferring said light beam, wherein at least one edge region of said sensor board is bent to enclose at least one edge region of said light guide plate and thereby prevents lateral light leakage of said illuminated keyboard.
