According to media report, Samsung and LG are developing a new low-refractive index Capping Layer (CPL) technology for small to medium-sized OLED panels in order to improve power efficiency.
Samsung & LG new low-refractive (CPL)
High-refractive index CPL is currently used in this industry to reduce power consumption and improve light directionality.
The addition of a low-refractive index CPL to the existing high-refractive index version could improve light usage, increase optical efficiency, and possibly extend the product’s life.
However, the incorporation of an additional layer may present manufacturing and cost challenges. Panel makers must persuade smartphone manufacturers such as Samsung Electronics and Apple of the benefits of this new CPL before it can be introduced.
Dongjin Semichem, Hodogaya, LAPT, and PNH Tech are among the companies actively developing low-refractive index CPL technology.
These firms have begun to deliver samples and form preliminary collaborations with panel manufacturers. The final supplier selection will be based on factors such as quality, cost, and existing partnerships.
According to Sammobile, Samsung and LG have previously demonstrated advances in OLED technology. Last year, Samsung introduced its Eco2 OLED panels, which boasted improved power efficiency and were later used in the Galaxy Z Flip 4 and Galaxy Z Fold 4.
However, some Samsung users, particularly those with flagship models, have recently reported display issues, including the appearance of pink, green, and white lines on their screens.
