摘要： The invention provides a display panel and a power control system of a drive circuit of the display panel. The power control system includes a timer controller, a power manager, and a drive circuit. The timer controller is used for receiving a first video signal and sending a finishing signal to the power manager after reading a decoding code for decoding the first video signal successfully. The power manager is used for sending a first drive voltage and a second drive voltage to the drive circuit after receiving the finishing signal. The power control system reduces the time difference between the video signal and the voltage, thereby avoiding the black screen problem.
