Abstract
A liquid crystal (LC) panel includes a plurality of data lines and a plurality of leads connected to the data lines, the driving circuit of the LC panel includes a monitor module and a data-driving module, the data-driving module includes a data latch unit coupled to the lead of the LC panel. The monitor module outputs a time sequence signal to control the data latch unit to output a display signal to the data line. The driving circuit of the LC panel includes a delay unit corresponding to the data line, and the time sequence signal is sent to the data latch unit through the delay unit. When the delay unit reaches a preset delay time, the time sequence signal controls the data latch unit to the display signal to a corresponding data line, and a delay time of a delay unit coupled to a long lead of the LC panel is shorter than a delay time of a delay unit coupled to a short lead of the LC panel.
