Abstract: A display apparatus for a vehicle is disclosed. A display apparatus for a vehicle according to an embodiment of the present disclosure includes: an organic light emitting diode (OLED) panel; a driving controller to output a driving signal; a first temperature detector in a first area of a rear surface of the OLED panel; a second temperature detector in a second area of the rear surface of the OLED panel; and a signal processing device to perform a first degradation compensation mode or a second degradation compensation mode based on a difference between a first temperature and a second temperature, wherein the signal processing device controls a luminance compensation value in the second degradation compensation mode to be greater than a luminance compensation value in the first degradation compensation mode. Accordingly, degradation may be reduced in an adaptive manner based on the temperature of each area of the panel.
