Abstract
A display apparatus includes a display panel, a light source part, a light source driving part and a used time calculation part. The light source part includes a light source providing the display panel with lights. The light source driving part includes a boost part outputting a light source driving voltage and a light source driving chip controlling the boost part. The used time calculation part detects an initial drive time during which an initial driving voltage is supplied to the light source driving chip and a normal drive time during which a normal driving voltage is supplied to the light source driving chip, and calculates a used time of the light source by using the initial drive time and the normal drive time. Thus, a real used time of a light source may be provided to correctly estimate lifetime of a light source.
