The light guiding plate is disposed under the light shielding plate. The reflecting plate is disposed under the light guiding plate. The light shielding plate, the light guiding plate and the reflecting plate are stacked with each other so as to form a middle area of the backlight module. An edge of one of the light shielding plate and the reflecting plate is folded and stacked with the other one of the light shielding plate and the reflecting plate so as to form an edge area of the backlight module. The middle area and the edge area are at equal height."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light keyboard","description":"A light keyboard includes a base, a plurality of keyswitches and a backlight module.
