Abstract
The invention provides a display circuit and a LCD having the display circuit. The display circuit includes a display unit, a level shifter, a timer controller, and scanning circuits. Each scanning circuit includes a first voltage stabilizing circuit including first and second field effect transistors. Source electrodes of the two transistors are connected to the level shifter. The scanning circuits send a first group of scanning signals to the display unit in sequence in a first period of time, and send a second group of scanning signals to the display unit in sequence in a second period of time. The timer controller sends a control signal to the level shifter in a time difference between the two groups of signals. The level shifter converts the control signal to a high level signal and sends it to the two transistors to enable the two transistors to be under reverse bias.
