OLED Display Technology Improving
There are numerous technology improvements coming to OLED displays such as
- deuterium (30% power savings),
- tandem RGB OLED stack (20%-40% power savings, increased brightness),
- phosphorescent blue OLED emitter (25% power saving as per UDC, improves lifetime),
- eLEAP/VIP (photo patterning, eliminates FMM, larger aperture ratio boosting brightness, efficiency and lifetime),
- CoE (reducing number of photomasks and increasing power savings) and other features that will increase OLED battery life, brightness and lifetime.
LGD is improving WOLED technology every year. It reached 3,000 nits peak brightness in 2024 using MLA+, optimizing lens shape, improved materials, improved polarizers, and optimization algorithm.
According to Ross Young’s presentation,
“LGD has been continuously developing a 4-stack WOLED solution, which could potentially allow them to remove MLA due to the high cost of the MLA materials and a narrower viewing angle. It is expected in 2025 with a peak brightness of 3,700 nits.” In 2024, QD-OLED by SDC also achieved peak brightness of 3,000 nits at the same power consumption level as 2023 models through new AI algorithms and luminance boosting technology.
As per Ross,
“In 2025/2026 – QD-OLED eliminating the separate CF/QD substrate. QD would be printed on the encapsulation layer with just 1 substrate used. It would boost brightness to 3,600 nits+ as targeting 4,000 nits in 2025.”
