OLED is currently the dominant technology in everything that has a screen, especially in the world of smartphones and televisions. However, despite all its advantages, it is still a technology that has a serious problem… Burn-in.
Obviously, all manufacturers have invested in various strategies, techniques, and even changes in production lines to reduce it, but it still exists, and when it attacks… It's ugly. In fact, burn-in was for many years used as a weapon and justification by Samsung against LG, to continue investing in QLED (LED with Quantum Dots) instead of betting everything on OLED or variations of the same technology.
Well, there are advances in defense against burn-in!
OLED's biggest problem seems to have a resolution in sight!
So, as you can imagine, OLED is nothing new to anyone. It's a technology that's starting to appear in mid-range TVs, it's already in almost every smartphone worth its salt, and it's even started to appear in the world of monitors. In fact, the arrival of OLED in the world of monitors created a huge range of business opportunities, which users are now taking full advantage of.
All this investment means that burn-in is, nowadays, almost outdated. However, it is not yet 100% outdated. Especially in the world of computers, where it's completely normal to have static images for hours on end.
Well, to put this problem into the past once and for all, a team of researchers from the University of Cambridge has come to a conclusion. You just need to better control the blue light emitted by the panel's diodes. In other words, to end the problem, it is necessary to attack the root of the problem.
Where does the Burn-In come from?
Typically, burn-in results from insufficient brightness coming from the blue light-emitting diodes present in the OLED panel. Therefore, if it is possible to have finer control of this very light emission, it will be much easier to avoid or circumvent burn-in.
In addition, the team of researchers also came up with a new way of encapsulating light emitters in alkylene insulating strips, improving efficiency, making the entire process simpler, and therefore potentially cheaper for manufacturers.
However, obviously, this discovery will not be implemented immediately. But technology has these things… So many things are discovered, almost every day, that while we wait for something new, another 3 or 4 are already hitting the market.
In short, OLED is getting better and cheaper. It's a reason to be happy.
