OLED display technology has revolutionized the way we view screens, but it is not without its flaws. One of the main issues with OLED panels is the limited full-screen brightness and the problem of burn-in. These challenges can be directly linked to the inefficiency of blue OLED subpixel technology. Blue OLED technology is less efficient than red and green subpixels, leading to lower light production, higher power consumption, and increased heat generation.
LG has recently introduced a new technology called “Dream OLED” panel, which aims to address the limitations of blue OLED technology. The new panel utilizes blue phosphorescence technology, which is more efficient and long-lasting compared to traditional fluorescent emission tech. By using a dual-stacked technique with both phosphorescence and fluorescent blue OLED, LG hopes to achieve better efficiency and longevity in their OLED panels.
The implementation of this new technology is complex, with LG not using a pure OLED RGB substructure in their panels. LG’s WOLED panels have an all-white OLED emission layer passed through RGB filters, while Samsung uses all-blue OLED emission to excite an RGB quantum dot layer. This new Dream OLED technology aims to improve full-screen brightness and longevity while reducing burn-in concerns.
LG’s Dream OLED panels are currently under production evaluation and could be commercialized within the year. While actual monitors or TVs with these panels may take a little longer to hit the market, LG is making significant progress in addressing the challenges of OLED display technology. The Dream OLED panels could potentially match LCD technology in terms of full-screen brightness while alleviating burn-in worries.
LG’s innovative approach to OLED display technology with the Dream OLED panel shows promise in overcoming the limitations of traditional OLED panels. By improving the efficiency and longevity of blue OLED technology, LG is taking a significant step towards creating brighter, longer-lasting OLED displays. While the full potential of Dream OLED panels remains to be seen, it is clear that LG is moving in the right direction towards optimizing OLED technology for a better viewing experience.
