Samsung and LG unify their forces for new display technology
Two South Korean tech giants, Samsung and LG, have combined their efforts to develop a new display technology.
Samsung Display and LG Display are delving into the possibilities offered by a new low-refractive index Capping Layer (CPL) technology for small to medium-sized OLED panels. This technology currently uses a high-refractive index CPL, which has been beneficial in reducing power consumption and enhancing light direction. Introducing low-refractive index CPL could improve light utilization, optical efficiency, and potentially increase the product's lifespan.
Nevertheless, there are some obstacles with implementing an additional layer, such as manufacturing challenges and cost implications. It is important for panel manufacturers to demonstrate the advantages of this new CPL to smartphone producers such as Samsung Electronics and Apple. Companies like Dongjin SEMICHEM, Hodogaya, LAPT, and PNH Tech have been developing low-refractive index CPL technology, and have started providing samples and entering preliminary stages with panel manufacturers. The ultimate selection of suppliers will be based on aspects like quality, cost, and existing relationships.
Samsung and LG unify their forces for new display technology
Samsung and LG have previously shown innovation in OLED technology, with Samsung having introduced Eco2 OLED panels last year. These panels offer improved power efficiency and have been used in the Galaxy Z Flip 4 and Galaxy Z Fold 4. However, some Samsung users, particularly those using flagship models, have reported display issues such as pink, green, and white lines appearing on their screens.
Apple is also working together with Samsung Display and LG Display on creating a bezel-less OLED display for iPhones. This endeavor requires the movement of electronic components from the bezel underneath the screen and advances in Thin Film Encapsulation (TFE) and Under Panel Camera technologies. Despite facing challenges such as potential antenna interference and durability concerns, Apple is addressing these technical issues with the support of its partners.
The completion and implementation timeline for these new OLED technologies is not clear yet. However, it is expected that future devices such as smartphones, tablets, and laptops might feature OLED screens that are brighter, more power-efficient, and have longer lifespans.
