Abstract: A state indicating device, which is adapted in an electronic device, includes a state detecting circuit, a controller, a driving circuit, and an LED device. The state detecting circuit is configured to detect an operation state of the electronic device to generate a detection signal. The controller generates a control signal according to the detection signal. The driving circuit generates a driving signal according to the control signal. The LED device displays an indication state according to the driving signal, in which the indication state is configured to indicate the operation state.
