Thin backlight module and thin light emitting keyboard

Abstract

The invention discloses a thin backlight module and a thin light emitting keyboard, the thin backlight module comprises a thin light guide plate and at least one LED light source, and the thin light emitting keyboard comprises the thin backlight module, a plurality of key structures, a plurality of keycaps and a base plate. The thin light guide plate comprises a light outgoing side, multiple groups of first buckles, multiple groups of second buckles and a plurality of microstructure patterns, wherein a plurality of key installation regions are defined at the light outgoing side, and a first buckle and a second buckle are set oppositely in each key installation region so as to form the corresponding key structure. The LED light source is used for providing light to enter into the thin lightguide plate and forming outgoing light at the key installation region through the microstructure patterns. Each keycap is connected and arranged at the top end of the key structure, and the base plate is arranged at a bottom side of the thin backlight module. Thus, overall thickness of the backlight module and the keyboard can be reduced effectively, and the demand of thinning of the current products is satisfied.

Description

technical field [0001] The invention relates to the field of backlight modules, in particular to a thin backlight module and a thin luminous keyboard. Background technique [0002] With the development of today's light supply technology, various electronic products with light-emitting functions emerge as the times require to provide users with a more excellent experience. For example, the keyboard, which is the main input device of a computer or notebook computer, is a very popular light-emitting electronic product at present. The early keyboards did not have luminous efficiency, and then in order to realize lighting prompts and decorative functions, related manufacturers used light supply structures as light sources to light up each key separately when it was driven. [0003] On the other hand, according to the market demand, electronic products have gradually developed towards thinner and lighter in recent years. The above-mentioned keyboard products also have the same de...

AI Technical Summary

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide a thin backlight module and a thin luminous keyboard in order to overcome the defects of the prior art that the overall thickness of the luminous keyboard product is relatively thick, the assembly takes a long time and the product cost is high.
