LG has unveiled a groundbreaking OLED technology named 'Dream OLED,' which significantly enhances the efficiency and lifespan of blue pixels.

This innovative Dream OLED technology utilizes a two-stack tandem structure that merges fluorescent and phosphorescent materials for blue light, resulting in a 10-20% improvement in efficiency.

Traditionally, blue pixels in OLED displays have been less efficient and degrade more quickly than their red and green counterparts, which contributes to burn-in issues.

Burn-in is a phenomenon where static images displayed for extended periods lead to permanent 'ghost' images due to pixel degradation.

To combat burn-in, manufacturers often implement techniques like pixel dimming and pixel shifting to alleviate the stress on static images.

In a related development, Apple has introduced a similar tandem OLED technology in their 2024 iPad Pros, which enhances brightness and lifespan but does not specifically tackle blue pixel degradation.

The blue phosphorescent material essential for LG's Dream OLED technology is supplied by Universal Display Corporation.

LG is set to assess the performance of Dream OLED for mass production within the year, with expectations for commercialization in one to two years.
