Abstract: A display device includes a gate scanning circuit and a driver IC. The driver IC includes a voltage detection circuit for detecting a voltage level of an external power supply, a voltage generation circuit for generating the voltage for driving the gate line, a switching circuit for switching between the output voltage of the voltage generation circuit and the voltage of the external power supply, and a drive circuit. Upon detection of the voltage outside of the predetermined voltage range by the voltage detection circuit, the switching circuit supplies the voltage of the external power supply to the gate scanning circuit. The gate scanning circuit selects all gate lines for outputting the voltage of the external power supply. The drive circuit supplies the GND level to all the source lines.

Abstract: According to one embodiment, a liquid crystal display device includes a first substrate, a second substrate, a liquid crystal layer, and a first drive module. A first source line is located between a first divisional electrode and a second divisional electrode. One frame period includes a first display period, a second display period, a sense period, and a first pre-charge period. The first drive module supplies a first image signal having a first polarity to the first source line in the first display period, supplies a first pre-charge signal having a second polarity to the first source line in the first pre-charge period, and supplies the first image signal having the first polarity to the first source line in the second display period.
