OLED display technology has long been praised for its stunning visual quality and vibrant colors. However, it is not without its fair share of problems. One of the major issues with OLED displays is the limitations involving blue OLED subpixel technology. Unlike red and green subpixels, blue OLED technology is much less efficient, producing less light at a given power and requiring more power while producing more heat at comparable brightness. This inefficiency has been a barrier to creating OLED panels that can offer strong full-screen brightness and good longevity with resistance to burn-in.
LG’s Innovative Solution
LG has recently introduced a new “Dream OLED” panel technology that aims to address the longstanding issues with blue OLED technology. The innovation involves a new panel utilizing blue phosphorescence, a more efficient technology compared to the previous fluorescent emission tech used for blue OLED. The new LG panel reportedly uses a dual-stacked technique with both phosphorescence and fluorescent blue OLED, in an effort to achieve better efficiency and longevity.
The implementation of this new technology is complex, as both LG and Samsung, the two main players in OLED panel tech, do not utilize a pure OLED RGB substructure. LG’s WOLED panels have an all-white OLED emission layer that is then passed through RGB filters, while Samsung uses an all-blue OLED emission which then excites an RGB quantum dot layer. The new blue OLED solution is expected to enhance the efficiency and lifespan of OLED panels, addressing concerns related to burn-in and full-screen brightness.
LG’s Dream OLED panel technology is currently under production evaluation and could be commercialized within the year. While this means that LG could begin manufacturing the panels for sale within a year, it will take some time before PC monitors or TVs with the new panels hit the market. The introduction of this new technology by LG signals a significant advancement in OLED display technology, raising hopes for OLED panels that can rival LCD displays in terms of full-screen brightness and longevity, while mitigating issues related to burn-in.
LG’s efforts to improve blue OLED subpixel technology showcase a promising future for OLED display technology. By addressing the inefficiencies associated with blue OLED, LG’s Dream OLED panel technology could revolutionize the industry and pave the way for OLED panels that offer unparalleled visual quality and longevity. While the exact impact of this new technology remains to be seen, it is clear that LG is taking a significant step towards advanced OLED display solutions that can compete with traditional LCD technology.
