The persistence of images on the TV screen during frame transitions can be quite bothersome for viewers. This is one of the challenging problems that TV manufacturers need to solve to provide a more immersive viewing experience.
What is image retention phenomenon?
Image retention occurs when part of an image continues to appear on the TV screen after that frame has disappeared. For example, if you pause on a news broadcast on TV and later switch to watching a movie, you will still see the image of the news anchor on the screen. Although this phenomenon usually disappears after a few seconds, it's still enough to make viewers uncomfortable.
Similarly, if users play an electronic game for extended hours and days, the on-screen display indicators can potentially cause permanent image retention. This occurs when pixel points become 'dead,' causing these blurry spots to continuously display instead of disappearing.
Samsung's approach to solving the issue of image retention. TVs utilizing outdated CRT or Plasma technology may encounter this condition. Image retention not only compromises user experience but is also believed to reduce screen contrast, diminishing the sharpness and vibrancy of images.
The key to addressing this discomfort lies in the TV's display mechanism. In this process, images are reproduced as light passes through pixels with three primary colors - red, green, and blue (RGB). When these pixels wear out or lose functionality, the RGB trio cannot transform into new images while retaining the old ones. This results in the persistence of the old image's blur on the new image.
As a pioneer in optimizing user experience, Samsung has tackled this challenge with Quantum Dot - a quantum inorganic dot technology that remains unaffected over time. Thanks to this, pixels have the ability to display colors seamlessly, completely eliminating the issue of image retention.
Simultaneously, Quantum Dot technology also enhances pixel longevity, combined with features that minimize this phenomenon such as color balance, standby screen, etc. This allows Samsung to confidently offer a 10-year no image retention warranty, enabling users to comfortably enjoy an 8K resolution TV - currently the highest in the market.
The second-generation Quantum Dot technology applied by Samsung in premium QLED TVs, combined with brightness ranging from 1500-2000 nits, ensures the display of images with complete and authentic colors. Thanks to continuous innovative efforts to deliver an excellent user experience, Samsung QLED is certified by the German technology magazine Video as free from image retention, making it one of the most durable screens in the market.
Furthermore, Samsung has become the first company in the TV industry to receive certification for the safety of 'no harm from LED light radiation' from the Underwriters Lab Laboratory (UL) in the United States and eye safety certification from the Verband Deutscher Elektrotechniker (VDE) association in Germany. This enhances the relaxation and ease of users' entertainment time, making the interaction with QLED screens more tranquil, providing a refined and comfortable audio-visual and entertainment experience.
