Abstract

The present invention provides a display driving circuit and a liquid crystal display panel with adding a first AND gate (AND), a second AND gate (AND) and a third AND gate (AND). Two input ends of each of the three gates receives a branch control signal and a conditioning signal (BURR), and the conditioning signal (BURR) first performs several high and low voltage level conversions and then maintains the high voltage level, respectively in the high voltage level durations of the respective branch control signals to make the signal outputted by the output end of the first AND gate, the signal outputted by the output end of the second AND gate and the signal outputted by the output end of the third AND gate first perform several high and low voltage level conversions and then maintain the high voltage level.
