Abstract
The present disclosure relates to display technologies, and particularly to a clock signal auxiliary circuit and a display device. The circuit can include a voltage detection circuit, a thermal sensitive sensing circuit, a control circuit, a switch selection circuit, and a signal amplification circuit. The clock signal auxiliary circuit can generate different detection signals according to different ambient temperatures during operation, and generate different control signals according to different detection signals, so as to turn on different channels according to different control signals, pull the clock signal that is finally output to the output end up to the correct potential, and generate correct scan signals at different ambient temperatures according to the clock signal pulled up to the correct potential.
