Abstract: A method of white balance adjustment and a liquid crystal display are disclosed. The method includes obtaining a total run-time of a liquid crystal display (LCD) panel; finding a corresponding white balance parameter according to the total run-time; and compensating the LCD panel with the corresponding white balance parameter, so as to adjust the corresponding white balance parameter according to a run-time of the LCD panel. The corresponding white balance parameter can be selected according to aging time of liquid crystals.

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.
