We're looking for any issues with the TVs as they age, including whether or not brightness decreases over time, uniformity issues (burn-in), or any outright component failures. To do so, we're running an accelerated test with 100 TVs over the next two years. The main goal of the longevity test is to get a better understanding of how long modern TVs should last. We'll post updates to this page and our YouTube channel, keeping you updated every step of the way. Every two months, we'll take uniformity and brightness measurements to see how they age over time and to look for any uniformity issues or change in brightness over time. Each TV will run for either 20 or 15.5 hours per day, for a total of 126 hours per week, turning off eight times a day to simulate normal use. To try to answer this question, we've decided to run 100 TVs that we still have in the lab from the last 2-3 years through a grueling 2-year accelerated longevity test to see how long they last. And the goal of it is to answer what seems like a simple question-how long can I expect my new TV to last? Today we’re changing that with the biggest test we’ve ever done. It keeps our reviews in the best state for when you buy a TV.ĭespite all this, there’s a huge hole in our reviews-a fundamental flaw we haven’t been able to fix. We keep the TVs in our lab until they’re no longer popular, comparing and retesting them with major firmware updates and newer test methodologies. So, it isn’t something we have an answer for at moment.We’ve bought and tested more than 380 TVs over the past nine years with our goal of helping you find the best one for your needs. As I’m sure you know though, we don’t typically feel comfortable speculating without having enough data to back it up. : This is a definitely a great question, and we’re doing our best to get a proper answer for everyone ASAP. I’m definitely not interested in keeping a $2000 TV if it’s vulnerable over time to noticeable burn in. Any idea of why this would be? Is this evidence of the new QD-OLED indeed being less resilient than the older WOLEDs, or can this be attributed to something in the testing methodology? I’m concerned because I just bought a 65-inch S95B and am in a relatively narrow time window to return the TV. Question: The first results seem to be showing image retention on the Samsung S95B, while the LG C2s and others are showing none. And since it’s the ‘fatiguing’ of specific areas of RGB pixels by prolonged exposure to static image elements that causes screen burn, it therefore follows that a pure RGB solution is going to be more susceptible to screen burn than a WOLED one. It all boils down to the fact that since LG Display’s OLED panels use a white subpixel in the creation of their pictures (something that Samsung has criticised them for over the years, on the grounds that they don’t deliver a pure RGB picture), the RGB subpixels in LG’s WOLED panels are subject to much less stress over time than QD OLED’s RGB subpixels are. This independent third party ‘proof’, as LG Display sees it, of QD OLED’s increased susceptibility to screen burn was then further followed up in the presentation with a straightforward explanation of why LG Display’s so-called WOLED technology is less susceptible to screen burn than its rival’s QD OLED system. The issue was particularly clear on Samsung’s S95B. These screen shots showed images from LG Electronics’ 2022 G2 and C2 OLED TVs that appeared to be completely free of any permanent image retention, alongside screen shots of two TVs that use Samsung Display’s QD OLED technology, Samsung’s S95B and Sony’s A95K, that both showed signs of image burn-in. LG’s claims were prompted by the results of ’s longevity tests, which suggest that TVs using Samsung’s QD-OLED panels, such as the S95B, could show signs of burn-in after just two months.įirst, LG Display showed screen shots taken from respected technology review website Rtings of the current results of long-term accelerated image retention tests it’s been running on a range of TVs since November 16th last year. Although engineers have yet to find a solution to this problem aside from workarounds that include pixel refreshing techniques, LG Display is now claiming that its OLED panels are less likely to get burn-in than QD-OLED displays, with a company rep calling out Samsung during a press call this week about how its competing screens are more susceptible to the problem. One of the biggest problems with OLED displays is burn-in, whereby static images (e.g., HUDs in video games) may become permanently affixed to the screen due to the aging of pixels, losing brightness as time goes on.
