Abstract: A backlight driving circuit includes a pulse width modulator, at least one time-delay sub-circuit and a driving sub-circuit. The pulse width modulator is configured to transmit a control signal including a plurality of pulses. The at least one time-delay sub-circuit is configured to delay at least one pulse of the control signal from the pulse width modulator that is transmitted to the at least one time-delay sub-circuit by a set time. The driving sub-circuit is coupled to the at least one time-delay sub-circuit, and the driving sub-circuit is configured to drive at least one of a plurality of light-emitting devices in a backlight module to be turned on or off according to a control signal from the at least one time-delay sub-circuit obtained after the at least one pulse is delayed.

Abstract: The present disclosure provides a communication method, an Internet of Things (IoT) terminal, a gateway device and an IoT system. A timestamp and a mask are used for operation, and a key is searched from a key table based on an operation result, such that the key can be dynamically generated based on changes of the timestamp without human intervention. Thus, the security of the IoT system is effectively improved without significantly increasing the computational consumption.
