Feedback circuit, heating circuit, display apparatus and display system
The present disclosure provides a feedback circuit for monitoring a heating loop, comprising a sample input module, a voltage conversion module and a main control chip. The sample input module has an input terminal coupled to the heating loop and configured to collect a voltage signal from the heating loop, and an output terminal electrically coupled to an input terminal of the voltage conversion module. The voltage conversion module has an output terminal coupled to an input terminal of the main control chip, and is configured to convert the voltage signal received from the sample input module into a voltage signal that the main control chip can withstand. The main control chip is configured to send a sample control signal to the heating loop, and calculate and output magnitude of the voltage signal inputted to the sample input module according to the voltage signal outputted by the voltage conversion module.
