Abstract:
Disclosed are an overcurrent protection driving circuit and a display apparatus. The overcurrent protection driving circuit includes a power supply circuit, a current feedback circuit, a current detection circuit, a level output circuit and a switching circuit, the power supply circuit outputs a direct current voltage to a display panel via the switching circuit, the current feedback circuit converts a voltage signal transmitted by the power supply circuit to the display panel to a current signal and feeds the current signal back to the current detection circuit, and when a current value corresponding to the current signal is smaller than an overcurrent protection current threshold value, the current detection circuit outputs a first level signal to control the switching-off of the switching circuit to cut off the supply of power from the power supply circuit to the display panel.
