Yes. Have you ever seen burned-out LCD displays in restaurants with dark blotches all over the picture? This is called burn-out and LCD televisions running at full intensity risk this problem. OLED televisions risk burn-in where television station logos or video game scores remain on the screen for the life of the TV (also known as image retention). TVs also begin looking brown as the blue sub-pixel is in overdrive and burns out the quickest. Corrective video calibration can lengthen the time of enjoying an accurate and pleasing image without these disastrous results.
