Abstract: A display apparatus includes a display panel, a timing controller and a power management integrated circuit (PMIC). The timing controller is to control an operation of the display panel and to store a plurality of fault patterns to be displayed on the display panel to represent that a plurality of defective phenomena have occurred. The PMIC is to supply a first power supply voltage to the timing controller and to monitor whether the plurality of defective phenomena have occurred. When a first defective phenomenon among the plurality of defective phenomena is sensed, the PMIC is to store first fault data and to shut down the display panel. When the first defective phenomenon is sensed, the timing controller is to control the display panel to display a first fault pattern corresponding to the first defective phenomenon among the plurality of fault patterns before the display panel is shut down.
