  • Patent number: 11521529
    Abstract: An electrostatic ignition protection method of a source driver of a display device and a display device are provided. When a time controller detects that a source driver has static electricity, the time controller controls the source driver not to output a driving signal for a preset duration and the preset duration is greater than an ignition threshold duration. This prevents the source driver having static electricity from accumulating enough heat in a short time to burn and fire.
