AI Technical Summary
Technical Problem
Existing backlit keyboards face challenges in achieving uniform illumination and a thin profile, making it difficult to improve the overall user experience without affecting other components.
Method used
The design employs a separate second circuit layer and auxiliary layer, combined with a light guide layer and a pattern layer. Signal interference is reduced through the auxiliary layer grounded by the bracket, thereby achieving uniformity and thinness of the light-emitting module.
Benefits of technology
The backlighting uniformity and overall flatness of the backlit keyboard have been improved, reducing interference with signals from components below and enhancing the user experience.

Abstract
The utility model provides a light-emitting keyboard which comprises a bracket, a plurality of keycaps, a first circuit layer and a light-emitting module. The key caps are arranged on the bracket and connected to the bracket. The first circuit layer is arranged between the keycaps and the bracket. The light-emitting module is arranged below the bracket and comprises a substrate, a second circuit layer, an auxiliary layer and a plurality of light sources. The second circuit layer is disposed on the substrate. The auxiliary layer is arranged on the substrate and is separated from the second circuit layer. The light source is disposed on the substrate and electrically connected to the second circuit layer. The luminous keyboard provided by the utility model can improve the luminous uniformity and can be thinned.
