The great Achilles heel of OLED televisions has to do with their brightness peaks, which are much more limited on an LCD model. It is true that little by little we are seeing new technologies that improve this limitation, such as the new LG OLED.EX panels that will debut the Philips OLED807, but it is still a problem that greatly affects when choosing a TV.
As expected, hehe R&D divisions of the main manufacturers of this type of OLED panels are working at full capacity to come up with a solution. But they are not the only ones, since the main universities in Korea have been working on a solution for years.
Will improve the brightness level of an OLED TV by 30%
Recently, we told you about the discovery made by the Korea Advanced Institute of Science and Technology (KAIST) and the Electronics and Telecommunications Research Institute (ETRI) that promises to improve the brightness level.
Now researchers at the National Taiwan University, led by Professor Chung-Chih Wu, have just announced that they have succeeded in developing a 3D pixel configuration for OLED devices that improves light extraction, achieving an emission that exceeds the performance of a traditional OLED panel by up to 30%.
To do this they use a structure of 3D reflective pixels filled with a patterned high-index material. Created with different sizes, they found that the smaller the pixel, the greater the efficiency. Furthermore, the used filler is introduced into the concave region of the pixel by vacuum evaporation through small openings in the aligned thin metal mask (FMM), completing the configuration of reflective 3D pixels.
The truth is that the results achieved by this group of researchers from the National Taiwan University are impressive, although the bells should not yet be launched on the fly. We are facing an investigation just been published so there is still a long way to go.
But it is also true that these advances are excellent news for the sector. There are more and more options to allow the next generations of OLED televisions achieve brightness levels that bring them closer to their great rivals.
Little by little, organic light-emitting diode panels have significantly improved their performance. It is true that the first generations did suffer many retention and burn-in problems, but as new technologies have been implemented, such as LG’s Brightness Booster, the results have been improving, with higher quality OLED Smart TVs arriving without so many problems. after prolonged use.
And it is clear that the next generations of OLED TVs will have much higher brightness levels than the first models. In addition, if they continue to lower the price of these types of panels and improve their great problem, we are sure that LCD technology will give way to OLED, just as it happened at the time with plasma screens.
