Abstract

This application provides a drive circuitry for a display panel and a display device. The drive circuitry includes a drive circuit board, a power chip, a driving chip, a detection circuit, and a control circuit. The detection circuit detects a logic voltage at a logic signal receiving terminal and outputs a control signal. The power terminal of the driving chip is coupled to the power chip through the control circuit. The control circuit controls to turn on or turn off the coupling between the power chip and the driving chip according to the control signal.
