Recent reports indicate that two major players in the display industry, Samsung Display and LG Display, are working on developing OLED panels that offer higher efficiency and longer lifespan. As leading manufacturers of OLED panels for smartphones, tablets, laptops, and televisions, their products are utilized by various brands worldwide. Last year, Samsung introduced the Eco2 OLED panel, known for its enhanced energy efficiency, which is already being used in the Galaxy Z Flip 4 and Galaxy Z Fold 4.
The focus of their research lies in the development of OLED panels that incorporate a low-refractive index Cover Layer (CPL). This extremely thin layer covers the cathode and helps reduce light losses caused by reflections from nearby electrodes during emission. The current CPLs used have relatively high refractive indices, but adding a layer of low-refractive index CPL could further minimize light losses, thus improving overall efficiency, energy consumption, and product lifespan. However, it should be noted that incorporating low-refractive index CPLs might potentially increase the cost and complexity of OLED panels.
LG has already employed a similar technology, known as Micro Lens Array (MLA), in their large-sized OLED panels used for televisions. This layer consists of billions of tiny convex lenses that collect and prevent emitted light from reflecting in the surroundings. As a result, OLED panels equipped with MLA can achieve a 20% increase in brightness while maintaining the same power consumption.
Both Samsung Display and LG Display are reportedly in talks with their major clients, including Apple and Samsung Mobile Division, to discuss the possible adoption of these higher-cost OLED panels. Should the clients agree, LG and Samsung can proceed with developing OLED panels for smartphones, tablets, and even laptops.
Currently, several companies are involved in developing CPL layers for OLED panels, including Dongjin Semiconductor, Hodogaya, Labto, and PNH Tech. Dongjin Semiconductor, Hodogaya, and Labto have already engaged with Samsung Display, while PNH Tech is part of LG Display's supply chain. These smaller OLED material manufacturers have sent samples to LG and Samsung Display, and if Apple and Samsung Mobile Division give the green light, OLED panels with low-refractive index CPLs could go into mass production.
Looking ahead, Samsung may introduce smartphones, tablets, and laptops equipped with these new OLED screens, featuring increased brightness, reduced energy consumption, and longer lifespans. The continuous advancements in OLED technology promise even more exciting developments in the display industry, benefiting consumers with enhanced viewing experiences and energy-efficient devices.
