Title:
LIGHT-EMITTING KEYBOARD
Document Type and Number:
WIPO Patent Application WO/2024/021048
Kind Code:
A1
Abstract:
A light-emitting keyboard provided in the present invention comprises membrane switches, keycaps, scissor feet and light-emitting assemblies. Each light-emitting assembly comprises a bottom plate, an insulating layer on the bottom plate, a circuit layer located on the insulating layer and provided with a plurality of circuits, and a protective layer covering the circuits and exposing end parts of the circuits, light-emitting particles mounted on the two spaced end parts and communicated with the end parts, a layer structure arranged on the outer sides of the light-emitting particles to achieve protection and lens effects. The bottom plate, the insulating layer, the circuit layer and the protective layer form a light-emitting assembly circuit board supporting the membrane switch below. Snap joints that extend upward to pass through the membrane switch and are connected to lower edges of the scissor feet are arranged on the light-emitting assembly circuit board. The positions of the light-emitting particles correspond to the key caps. When the circuit layer is energized, the light-emitting particles emit light to illuminate the key cap, so that the light-emitting function is achieved, and the light effect is good. Because there is no need to provide holes on the bottom plate for light transmission, the strength of the bottom plate is not affected. In addition, the circuit layer, the insulating layer, the protective layer, the light-emitting particles and the layer structure can be conveniently arranged by utilizing the characteristics of high strength of the bottom plate, so that costs are low, the light and thin effect is achieved, and the heat dissipation effect is good.
