A gate driver IC includes a first diode, a second diode, a first comparator, a second comparator, and a judgement circuit. The first comparator compares a first potential difference between both ends of the first diode and a first threshold. The second comparator compares a second potential difference between both ends of the second diode and a second threshold. Based on comparison results of the first comparator and the second comparator, the judgement circuit determines occurrence of disconnection.

Drive circuit, liquid crystal drive controller, and liquid crystal display device

A drive device according to the present invention is located in a liquid crystal panel. The drive device is a source driver IC that drives a pixel region of the liquid crystal panel. The drive device includes a comparison circuit and a determination circuit. The comparison circuit detects a potential difference between a potential of a first analog power supply and a potential of a second analog power supply, an analog power supply input from the outside being divided into the first analog power supply and the second analog power supply. The determination circuit determines that it is an abnormal condition when the potential difference detected by the comparison circuit is greater than or equal to a predetermined threshold value.
