Abstract
A display power circuit is provided. The display power circuit includes a power supply circuit that receives an input voltage and generates an output voltage to power a display. A power switching device couples the output voltage from the power supply circuit to provide a display voltage for the display. A monitor circuit generates a shut down signal based on a change of the output voltage relative to the input voltage exceeding a predetermined threshold indicating a short circuit condition of the display voltage. A control circuit disables the power switching device based on the shut down signal if the short circuit of the display voltage is detected.
