One of the biggest disadvantages of OLED screens to date is the lower brightness compared to LED-backlit screens, therefore, it is not recommended to install digital signage on ultra-thin OLED displays in a bright environment.

Thanks to the latest generation - LG monitors, which are called OLED-EX - the brightness of its displays has been increased by 30%. LG Display has been producing large-format OLED displays since 2013, making it the undisputed global market leader.

EX technology differs from previous OLED technology, which was first used in the display panel instead of hydrogen, an important component of organic light emitting diodes, and deuterium (heavier hydrogen) with a stronger and more stable structure.

Deuterium is twice as heavy as regular hydrogen and occurs naturally as one of about 6,000 hydrogen elements in very small amounts. LG Display extracted deuterium from the water and applied it to organic light emitting panels. This makes the plate on which the deuterium is applied more stable, physically durable and maintains a high level of performance even with increased brightness.

In addition to physical changes, LG Display also uses artificial intelligence to improve image quality. A machine learning-based (ML) personalization algorithm, developed independently of the LG display, allows better control over the organic elements. millions of organic pixels emitting light (based on 8K resolution) and thus more precisely control the amount of power delivered to reproduce the detail and color of the image. A feature that can be useful for digital signage.

Thanks to the new technology platform, the already thin bezel of OLED screens has also been reduced by 30%. Due to the new production technology, the OLED panel aperture, which was considered a technical limitation, was reduced by 30% from the current 6mm (mm) to 4mm based on the screens 65 degrees.

From Q2 2022, all displays manufactured by LG Display in South Korea (Paju) and China (Guangzhou) will be based on OLED.EX.
