The wear and tear of screens and Smart TVs with OLED technology could be a thing of the past

OLED televisions have positioned themselves in the market thanks to their image quality and the sharpness of vibrant colors. The only drawback that these screens may have is durability. After intense use tests of 20 hours a day for 10 months, all Smart TVs suffer significant damage such as burns or changes in brightness.

This problem may have its days numbered thanks to a study by the University of Cambridge published in the journal Nature. The research team has designed OLED televisions with ultra-thin band blue lights that prevent unwanted energy transfer. This has been discovered to be the main cause of screen burn-in in record time.

Samsung has studied this technology for years to integrate it into its devices. The company intends to switch from blue fluorescent materials to phosphorescent versions to reduce energy consumption. This system could reach the screen iPhone in 2026 with the possible iPhone 18.

Blue OLEDs also have a shorter lifespan due to higher subpixel jitter. By using diodes that emit blue light along the narrowband spectrum, unwanted energy transfer can be avoided and pixel stability improved. All this translates into greater efficiency.

The OLEDs of the future could be more efficient

By eliminating unwanted energy transfer from the panels, the consumption of the screens integrated into televisions, phones and tablets is reduced, reported TechRadar. The challenge of the future will be to make the production of blue OLEDs within the reach of all manufacturers.

The prototype of the University of Cambridge It is in the research phase and will still have to pass various quality tests before it can be mass produced. The potential to extend the life of devices and reduce consumption can accelerate steps to integrate these OLEDs into the market.

At the moment there are some Smart TV models such as the LG C1 OLED or monitors such as the Alienware AW3423DWF with a QD-OLED panel that Resists burn marks relatively well with intense use. These high-end devices have intelligent pixel engraving functions, but this technology is far from lower-end models.
