  • Publication number: 20240404486
    Abstract: In a first transition period during which an operation mode transitions from a normal mode to a low power consumption mode, a VCOM generation unit in a power source IC changes a potential of a common electrode drive voltage VCOM from a potential of a first level (for example, 5 V) to a potential of a second level (for example, 12 V) so that a leakage current flowing through a pixel transistor is not generated during a pause period, a gate driver changes a potential of each gate bus line to 0 V, and a source driver changes a potential of each source bus line to 0 V.
