To maintain a QLED TV, use a dry microfiber cloth for daily dusting and a slightly damp one (with distilled water, sprayed on the cloth, not the screen) for smudges, always working gently in circular motions and avoiding harsh chemicals like alcohol or ammonia, which can damage the screen coating; unplug the TV before cleaning, and use built-in features like Samsung's Device Care for software maintenance.
QLED TVs tend to last around seven years, while LED TVs tend to last just over 6 years, thanks to their inclusion of a backlight. However, the lifespan of an average 4K TV will largely depend on the brightness of the screen, and how often it is used. A 4K TV that is well cared for could last well over ten years!
Drawbacks of QLED
Black Levels & Contrast Limitations: Even advanced local dimming cannot match OLED's pixel-level control for perfect blacks. Viewing Angle Fall-Off: When viewed from the side, QLEDs can show color and brightness degradation.
Don't use glass cleaners, like Windex®, on your TV. They may contain harsh solvents like acetone, alcohol, or ammonia that could damage your flat screen.
Turn off the TV and unplug the power cord. Lightly dampen a microfiber cleaning cloth with a few drops of water and gently wipe the stain. Important: Do not wet the sponge before wiping the TV.
This wider colour range means QLED TVs can display vibrant colours at any brightness level, from dark, shadowy scenes to bright explosions.
QLED stands for Quantum Dot LED, meaning that there is an extra layer of nanocrystals between the LED lights and the viewing screen. QLED TVs utilize an extra layer of red and green crystals to produce more pure and saturated colors than typical LED TVs.
OLED panels are also exceptionally thin and can be flexible, creating sleek, art-like displays on your wall. While offering more limited viewing angles, QLED TVs have an edge in bright rooms. Their backlight and anti-reflective layer help reduce glare, making QLEDs a top choice for well-lit spaces.
Under normal use, an LED, OLED, or QLED screen won't suffer image burn. However, if you leave your screen on a single channel for hours every day, then burn-in can become an issue, as it would with almost any screen.
What TVs last a long time? LED, OLED, and QLED TVs are known for their long lifespan, especially models from reputable brands like Sony, LG, Samsung, and Panasonic. LED TVs are particularly durable due to their solid-state nature, with OLED and QLED offering even better longevity.
QLEDs tend to last longer than OLEDs. However, both QLEDs and OLEDs may last thousands of hours before they start to degrade.
Dirty screen effect commonly affects LED, QLED, and other backlit TVs. This is because it directly affects the efficiency of the backlights. However, it is also an issue that can affect OLED TVs too. If any of the OLED pixels burn out at a different rate from the rest, then it will result in a patchy image.
You do not want to use tap water, since tap water often contains minerals that could leave streaks. Start with a dry microfiber cloth, wiping in gentle, circular motions. Then, use a spray bottle to spray another clean lint-free cloth with water.
Realistic QLED TV lifespan in years and hours
In everyday use, a solid QLED TV lifespan is typically around 7–10 years before most people notice clear aging in the picture. In hour terms, that's roughly 40,000–60,000 hours of viewing.
It's worth purchasing a QLED TV in either a 4K or 8K form. The bolstered resolution is perfect for the richer colours achieved by these displays! Just keep in mind that there's more 4K content than 8K content available! However, 8K models are still a worthwhile purchase.
Can TV Burn In Occur On A QLED TV? Not all major TVs on the market are susceptible to developing burn-in! QLED TVs, in particular, are actually invulnerable to burn-in. 4K QLED TVs are very unique in that they don't actually use pixels, but instead make use of 'Quantum Dot Technology' to replicate colours.
Initially, LED and QLED TVs are similar as they each use LCD panels with LED backlights. However, QLED TVs use a Quantum Dot layer that allows them to produce a wider range of colors. In terms of picture quality, QLED takes the cake, but LED is still very much worth looking at.
OLEDs are true emissive components that produce light on their own and do not require a light source. Meaning they produce a light that's more natural and less harsh on your eyes. OLED TVs also provide excellent color and contrast because they do not use light from other sources to display colors, as LCD/LED TVs do.
If you can take advantage of the latest screen technologies to protect your eyes from blue light, then we strongly recommend purchasing QLED screens. In addition to toning down the blue color, the QLED display has exceptional image quality.
But TV watching for long stretches of time can leave your eyes fatigued. What are the best conditions for TV viewing? A normally lit room, suitable for general activities, is best.
Avoid Using Household Chemical Cleaning Products
Ammonia and acetone, on the other hand, damage the screen by causing discolouration and forming a hazy appearance, thereby ruining the TV's visual quality. [Note: Even wet wipes with high alcohol content should not be used on TV screens.]
You should never use any type of window cleaner, soap, scouring powder, or any cleanser with solvents such as alcohol, benzene, ammonia, or paint thinner. Never use abrasive pads or paper towels. If you do, you can scratch the screen or strip the anti-glare coating off the screen and cause permanent damage.
Even a light touch can leave annoying fingerprints and smudges behind. Touching the screen with too much force could cause direct damage to the screen and the pixels. The reason we would recommend against even lightly touching your TV screen is because of the fingerprints that could be left behind.
