Display apparatus and control method thereof
First Claim
1. A display apparatus comprising a displayer which displays a picture and a brightness adjuster which adjusts a brightness of the displayer, further comprising:
- an optical sensor detecting circumferential brightness; and
a controller calculating criterion brightness data of the displayer on a basis of the circumferential brightness, and calculating brightness data of the displayer according to a variation of the circumferential brightness on a basis of the criterion brightness data so as to control the brightness adjuster to adjust the brightness of the displayer according to the brightness data.
