DISPLAY APPARATUS

Abstract: a display apparatus includes a boost converter configured to boost a voltage input thereto to a high potential voltage and to output the high potential voltage; a pixel power circuit configured to generate a pixel driving voltage for operation of pixels disposed in the display apparatus based on the high potential voltage, and to supply the generated pixel driving voltage to the pixels; a buck converter configured to receive the high potential voltage to convert the received high potential voltage to a logic voltage, and to output the converted logic voltage; and a driver power circuit configured to receive the output logic voltage, to convert the received logic voltage to an operating voltage for operation of the display apparatus, and to output the operating voltage. thus, even when power supplied from the vehicle's battery to the display apparatus is cut off, screen flashing is prevented from occurring.
