Liquid crystal display

A liquid crystal display (LCD), comprising:

• a substrate, comprising a pixel array section and a circuit arrangement section arranged on a first side and a second side of the pixel array section;
• a plurality of gate on array (GOA) units connected in series, disposed on the circuit arrangement section, for outputting a scanning signal to the pixel array section based on voltage levels of a plurality of clock signals and a voltage level of a start signal;
• a controller, for generating the plurality of clock signals and the start signal;
• a level shifter, electrically connected to the controller, for adjusting the voltage levels of the plurality of clock signals and the voltage level of the start signal;
• and
• an over-current protection circuit, electrically connected to the level shifter, for outputting an adjusting signal to the controller to turn off the LCD when a magnitude of one of the plurality of clock signals is over a predetermined value;
• wherein the plurality of clock signals comprise a first clock signal, a second clock signal, and a third clock signal, each of the plurality of GOA circuit units at each stage for outputting a scanning signal at an output terminal according to a scanning signal output by a GOA circuit unit at a previous stage, a scanning signal output by a GOA circuit unit at a next stage, a first constant voltage, a second constant voltage, the first clock signal, the second clock signal, and the third clock signal,
• wherein upon receiving the adjusting signal, the controller switches the clock signals and the start signal to a floating state, and then turns off the LCD.
