OLED display technology has long been admired for its stunning visual quality, but it is not without its problems. Two of the most prominent issues with OLED displays are limited full-screen brightness and panel degradation known as burn-in. These drawbacks are often directly linked to blue OLED subpixel technology, which is significantly less efficient than its red and green counterparts. As a result, blue OLED consumes more power, produces more heat, and produces less light at a given power level. Addressing these limitations is crucial to improving OLED technology as a whole.
LG’s Innovative Solution
LG has recently introduced a new “Dream OLED” panel technology that aims to address the inefficiencies of blue OLED technology. By utilizing blue phosphorescence in its new panels, LG is able to achieve better efficiency and longevity compared to traditional fluorescent emission tech. The new panels reportedly use a dual-stacked technique that combines phosphorescence and fluorescent blue OLED to improve overall performance. While the implementation of this technology is complex, it holds the promise of significantly enhancing OLED display quality.
Both LG and Samsung, the leading players in OLED panel technology, have faced challenges in creating OLED panels that offer strong full-screen brightness and resistance to burn-in. LG’s WOLED panels utilize an all-white OLED emission layer passed through RGB filters, while Samsung’s panels employ an all-blue OLED emission that excites an RGB quantum dot layer. The incorporation of blue OLED technology at a substructure level is crucial for overcoming these challenges and improving the overall performance of OLED displays.
LG’s new Dream OLED panel technology is currently undergoing production evaluation and could potentially be commercialized within the year. While it may take some time before PC monitors or TVs equipped with these new panels hit the market, LG’s efforts signify a significant step forward in addressing key issues with OLED technology. By enhancing full-screen brightness and longevity while minimizing burn-in concerns, LG’s Dream OLED panels represent a promising advancement in display technology. While the exact impact of these new panels remains to be seen, they are poised to play a critical role in shaping the future of OLED displays.
