SET- UP | OLED SCREEN BURN

OLED’S DIRTY LITTLE SECRET SCREEN TIME

As OLED screen technology enters the professional monitor world, there could be a hitch WORDS JULI AN M ITCHELL T ests by influential technology reviews site, RTINGS, have found screen burn can set in as quickly as two years after buying a new OLED television and by association, monitor. That’s much quicker than previously expected in OLED TVs. Screen burn, or burn-in, refers to an effect where part of an image that is no longer displayed is still visible on a different image, such as static logos that stay on the screen when running timecode, watching news channels and playing video games. The latest tests by RTINGS tested OLED for burn-in on a variety of content, from news and general TV to sports and gaming. During the testing period, the technology reviewers assessed and reported on the screens’ brightness and colour renderings every two weeks. The channels and content were respectively displayed in intervals of a five-hour ‘on’ period and one-hour ‘off’

period during a cycle that was repeated four times per day. The tests found that when the TVs were set to maximum brightness and were showing gaming content and news channels, they were most affected by burn- in, as both pieces of content feature static logos on screen most of the time. After 4000 hours, the TVs testing this content displayed the mark of these logos on the screen, even when the content wasn’t being played. SAMSUNG’S ACTION It is for this reason in part that Samsung decided to stop using OLED technology in its TVs in 2012 and proceeded to develop the new QLED technology. Samsung claims that their QLED TVs’ picture quality lasts for the lifetime of the product and there will not be any visible deterioration in colour

The tests by RTINGS tested OLED for burn-in on a variety of content, from news and general TV to sports and gaming over time due to the advanced Quantum dot technology – QLED uses inorganic Quantum dot material which is known to be durable and stays burn-in free. On the other hand, the organic material of OLED TVs potentially wears out over time. As such, Samsung QLED and LED TV sets have received a perfect score (10/10) for image retention in RTINGS’ test. The impartial tests seem to prove that Samsung’s QLED and Dynamic Crystal Colour UHD TVs aren’t susceptible to screen burn like other TVs and potentially monitors on the market, and as such Samsung is offering a market-leading ten- year screen burn warranty as a testament to the confidence in its QLED technology.
