Burn In On Sharp LCD HDTV
“Burn In” is a commonly used term to describe image retention; a condition that occurs when a previously displayed video image, such as a stock ticker, channel logo, video game score, for example, remains visible on a display well after it originally appeared.

It can be short-term visible (for hours to days) medium term (days to weeks) or permanent. The HD Guruoften reads about or hears HDTV salespeople claiming that LCD HDTV panels don’t burn in. The attached photos should dispel any such notion. They clearly show image retention on an LCD HDTV.
An industry source supplied the pictures, which were taken at a Bic Camera, an electronics retail chain store in Japan. Pictured is a Japanese model Sharp LCD HDTV used for a computer software ad. The retained images appear at the top-right as Japanese text and on the bottom-right as the price in yen .

The HD Guru spoke to Bob Scaglione, Senior Vice President of Marketing for Sharp Electronics USA. He acknowledged that pixels can get “stuck” on its LCD HDTVs, leaving a retained image. But, he added, powering off the display for an unspecified period can reverse the condition.
Mr. Scaglione alluded to consumers who ship their TVs back to Sharp USA complaining about burn in, but days later, when their LCDTVs are unpacked and tested at Sharp, the retained images were gone. He also stated the condition can be reversed by “exercising” the panel by playing “snow” (video noise) for an unspecified period of time.
