Abstract
Official abstract text for this publication.
A protection circuit of a backlight driver circuit includes a backlight driver circuit. The backlight driver circuit includes a backlight driver integrated circuit (IC), and the backlight driver IC includes a protection pin that controls the backlight driver IC to enter a protection mode. The backlight driver circuit further includes a protection circuit, and the protection circuit includes a monitoring unit that monitors a temperature of the backlight driver circuit. When the temperature of the backlight driver circuit exceeds a preset temperature, the monitoring unit sends the protection signal to the protection pin to control the backlight driver IC to enter the protection mode.
