Abstract
An LCD includes a substrate, gate on array (GOA) units connected in series, a controller, a level shifter, and an over-current protection circuit. The substrate includes a pixel array section and a circuit arrangement section. The GOA units are used for outputting a scanning signal to the pixel array section based on voltage levels of clock signals and a voltage level of a start signal. The controller generates the clock signals and the start signal. The level shifter adjusts the voltage levels of the clock signals and the voltage level of the start signal. The over-current protection circuit outputs 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. Therefore, the LCD is turned off for a while, preventing from being burnt out.
