Abstract
A switching circuit is signally-connected to an initial trigger signal, a detection circuit and the GOA circuit. Upon a low voltage level of a low potential signal, the switching circuit is turned on to transmit the initial trigger signal to the GOA circuit so that the LCD panel works normally. Upon a high voltage level of the low potential signal, the switching circuit is turned off so that the GOA circuit does not conduct the initial trigger signal to protect the LCD panel from burn-out.
