Ross Young, co-founder and CEO of DSSC (recently acquired by CounterPoint Research) has since shared some information on the topics discussed.
And many technological improvements are coming for Oled displays. We can mention the generalization of deuterium material (with an expected result of about 30% energy saving), the double layer of Oled RGB diodes used in tandem (prospects of 20% to 40% energy saving and increased brightness, see our news Samsung Display aims for 50% less power-hungry Oled screens), the integration of the phosphorescent blue Oled emitting material (25% energy saving according to the UDC and improved lifespan, see our news LG Display on the verge of significantly advancing Oled technology?) or the development of the eLEAP/VIP lithography process (eliminates the FMM mask, offers increased brightness, the same for energy efficiency and lifespan). These are the main development paths explored for some time now or in the process of being explored.
Focus on the White Oled developments by LG Display££££
LG Display has done a great job since the launch of the first Oled TVs in 2013. In 2024, thanks to the MLA 2.0 (or MLA+) process which optimizes the shape of the billions of lenses on the screen, the materials, the polarizers and the panel control algorithm, the peak brightness will reach 3,000 nits. A figure that was thought impossible just a few years ago. In 2025, the peak should reach 3,700 to 4,000 nits (see our CES 25 news > LG G5 Oled TV: 4,000 nits target). The question is: how does LG Display achieve this result? Is this a new improvement of the MLA 2.0 technology or a completely new White Oled panel with four layers of Oled materials plus the phosphorescent blue emitter for increased brightness and efficiency? As a reminder, LG Display had presented this 4-layer Oled panel to the world at the IMID (International Meeting on Information Display) conference held in the city of Jeju in South Korea in August. Ross Young, following the Display 360 Summit event, specified that this new panel with capacities substantially equivalent to those of the MLA 2.0 panels could allow LG Display to put this latter process, which is very expensive and therefore difficult to use on other TV series in the LG Oled range, on the shelf.
Focus on QD Oled developments by Samsung Display££££
On the Samsung Display side, QD Oled technology also allows for a peak brightness of 3,000 nits to be displayed in 2024, with unchanged energy consumption compared to the 2023 references, by the way. According to Ross Young, corroborating our information (see our CES 25 news > Samsung S95F QD Oled TV: 4,000 nits in sight), the 2025 QD Oled panels would display a peak of 4,000 nits thanks to the removal of the Quantum Dot film. The nanocrystals being directly printed on the encapsulation layer via the use of a single substrate would offer higher efficiency.
Other innovations could also soon see the light of day in Oled televisions, for example the Max Oled solution by Applied Materials (see our news Max Oled, new technology for Oled screens up to 3x brighter). In short, Oled technology, which faces strong competition from Mini LED with similar performance in many areas, absolutely must progress to withstand LCD screens offered at considerably lower prices, particularly very large specimens that are increasingly popular with consumers.
