LG Announces OLED EX Screen with Up to 30% Brighter Brightness

The evolution of OLED screens is here. In CES 2022 mood, LG unveiled its new OLED EX panel, with promise of being up to 30% brighter than the previous generation thanks to the incorporation of a chemical compound called deuterium. With this, the manufacturer intends to solve one of the main pains of OLED TVs today: the lack of brightness in brightly lit environments.

According to LG, the OLED EX panels will use deuterium compounds and custom algorithms to improve the stability and efficiency of organic light-emitting diodes. In practice, the algorithms will allow the screens to analyze both the environment where the device is and the content displayed to deliver the best possible image, with an adequate level of brightness, through machine learning.

Meanwhile, deuterium comes in as a kind of chemical stabilizer on OLEX EX screens. This compound is a gas isotope of hydrogen that is, it has the same number of protons also known as “heavy hydrogen”. The difference between the two atoms is the twice the mass of deuterium, which comes from an extra neutron in its atomic structure.

The light emitting diodes in traditional OLED panels are basically composed of carbon, hydrogen and oxygen. In OLED EX screens, LG managed to replace the common hydrogen atoms with the deuterium isotope, which, being heavier in mass, is able to emit electrons and consequently light with greater stability and efficiency.

The downside of relying on deuterium is its rarity in nature. Out of 6,000 hydrogen atoms, only one is the isotope. LG says it has managed to find a way to extract deuterium from water to apply the compound on a large scale to OLED EX panels, but this does not appear to be a simple process, nor is it cheap. For now, we don’t know how this will affect the price of TVs and monitors in the future.
