Abstract
A display panel driver circuit includes multiple drivers adapted for cooperatively driving a display panel and each operable under a protection mode, and an overheat protection device including multiple protection circuits, each of which controls a respective one of the drivers to operate under the protection mode in response to receipt of an enable signal, an interface circuit which transmits the enable signal to each of the protection circuits in response to receipt of a warning signal, and multiple temperature detection circuits, each of which is able to detect a temperature associated with a respective one of the drivers, and outputs the warning signal to the interface circuit based on the temperature thus detected.
