INPUT DEVICE WITH LUMINOUS PATTERNS
First Claim
1. An input device with luminous patterns, comprising:
- an input interface, having a predetermined light shading rate; and
a backlight module, disposed under the input interface, wherein the backlight module comprises;
a light source; and
a light guide plate, having at least a pattern, and the at least a pattern disposed on an upper surface or a lower surface of the light guide plate, wherein when the light source is turned off, the at least a pattern is unable to be shown due to a brightness of the light guide plate is lower than the predetermined light shading rate.

Abstract
The present invention discloses an input device with luminous patterns including an input interface and a backlight module. The backlight module includes a light source and a light guide plate. The input interface has a predetermined light shading rate and at least one pattern formed on the light guide plate. When the light source is turned off, the light passing through the light guide plate is too weak to show the pattern. When the light source is turned on, the luminous pattern is shown. One base plate of the input interface is made from a mixture of transparent plastic particles and light shading particles, and the at least one pattern is formed of the micro light guide structures. The present invention provides the advantages of increasing the light source utilization rate, reducing costs, simplifying the manufacture process, improving the shading uniformity, reducing the thickness of input device and decreasing abrasion.
