Abstract
A luminous keyboard and a membrane circuit luminous structure are provided. The membrane circuit luminous structure includes a first conductive layer, a second conductive layer and a plurality of IC-embedded luminous assemblies. When the first conductive layer and the second conductive layer are contacted with each other in response to a pressing action, the conduction between them is established. The plurality of IC-embedded luminous assemblies are installed on the second conductive layer. Each IC-embedded luminous assembly has a power terminal, a signal input terminal, a ground terminal and a signal output terminal. The power terminals are connected with each other in parallel. The ground terminals are connected with each other in parallel. The signal input terminals and the signal output terminals of the plurality of IC-embedded luminous assemblies are connected with each other in series to transmit signals.
