INDICATOR CIRCUIT AND ELECTRONIC DEVICE

摘要

An indicator circuit comprises a first logic circuit, a second logic circuit, a third logic circuit, an auxiliary power circuit, a switch circuit, and a light emitting diode (LED) circuit. The switch circuit controls whether the LED circuit lights or not, according to the first logic circuit, the second logic circuit, and the third logic circuit, to indicate connections to different data bandwidths.

主权项

1. An indicator circuit in an electronic device supporting a plurality of different bandwidths, the indicator circuit comprising:
a first logic circuit configured to output a first decision signal dependent upon whether or not the electronic device is receiving data by any one of the different bandwidths; a second logic circuit configured to output a second decision signal dependent upon whether or not the electronic device is connected to any one of the different bandwidths; a third logic circuit configured to receive the first decision signal and the second decision signal, and to output a third decision signal according to the first decision signal and the second decision signal; a light emitting diode (LED) circuit; and a switch circuit electronically connected to the LED circuit and the third logic circuit, configured to receive the third decision signal and control, according to the third decision signal, whether or not the LED circuit lights.
