While OLED is generally seen as offering the overall best picture quality of any current, consumer-level display technology, one flaw has always been pointed to the technology: its longevity. As time passes, OLED panels tend to lose their vibrancy, and are prone to pixel burn-in (as in, when static images are projected on the same pixels for extended periods of time, they tend to "memorize" the color and be locked in to emitting it). However, the incredible image quality given by OLED's contrast capabilities (where each individual pixel can reproduce pure black, in virtue of being off) means that researchers and companies have poured countless dollars towards improving the technology for commercial use.

Of course, tech is all about iteration, and there are always ways of improving a design - or the underlying technology. In this case, a team of German and Spanish researchers found that raising temperatures in the OLED panel manufacturing process (heating the polymers to within 80 to 90 percent of their glass transition temperature) allows for the creation of "ultrastable glasses." This means that the polymers are now arranged in their best possible configuration - at their lowest energy state - with smaller gaps between the material, which improves panel cohesiveness and reduces particle vibration. The result? Longevity and brightness increased by 15% over their non-heated counterparts. Now, the researchers are working with OLED manufacturers to try and implement this technique at the manufacturing level - at a sustainable cost.
