Title: DISPLAY DRIVE CIRCUIT AND LIQUID CRYSTAL DISPLAY PANEL
Abstract:
A display drive circuit and a liquid crystal display panel. A first AND gate (AND1), a second AND gate (AND2), and a third AND gate (AND3) are added, and a shunt control signal and a regulating signal (BURR) are respectively connected into two input ends of each of the first AND gate (AND1), the second AND gate (AND2), and the third AND gate (AND3). The regulating signals (BURR) respectively perform high-low potential conversion multiple times and then keep a high potential during high potential durations corresponding to the shunt control signals to enable signals output by the output ends of the first AND gate (AND1), the second AND gate (AND2), and the third AND gate (AND3) to perform high-low potential conversion multiple times and then to keep a high potential, so that the on states of control TFTs respectively controlled by the signals output by the output ends of the first AND gate (AND1), the second AND gate (AND2), and the third AND gate (AND3) are different at a signal near end and at a signal far end, and the maximum current appearing time of sub-pixels is inconsistent at the signal near end and at the signal far end, thereby avoiding signal burrs caused by instant overload.
