Samsung’s Low-refractive CPL for M15 OLED Material
Samsung Display, a trailblazer in display technology, is gearing up to revolutionize the smartphone market yet again. According to reputable sources from Korean media TheElec, the company has ambitious plans to introduce a low-refractive capping layer (CPL) for its OLED screens, marking a significant step forward in display technology. While commercial availability is expected at the earliest in 2025, the potential benefits of this innovation have the industry buzzing with excitement.
Currently, OLED screens dominate the smartphone landscape, widely using high-refractive CPL panels that offer the advantage of reduced power consumption. However, Samsung Display is poised to elevate this technology further by introducing a low-refractive CPL layer on top of the cathode. This layer promises to direct light from the emission layer toward the front of the display panel, minimizing light loss and thereby improving the overall optical efficiency of the display.
Collaborating with partners like Dongjin Semichem, Lapto, and Hodogaya Chemical Company, Samsung Display is meticulously testing this novel technology. Industry insiders suggest that the new low refractive index CPL overlay could debut on M15 OLED materials, with potential incorporation into the Galaxy S series of phones as early as 2025, and possibly extending to iPhones in the future.
Despite the tremendous potential this technology holds, there are challenges to overcome. Implementing low-refractive CPL overlays could lengthen the production process and lead to increased costs. As a result, convincing major customers like Samsung Electronics and Apple to adopt this revolutionary approach will be essential.
As of now, Samsung Display’s flagship OLED panels are constructed using M12 material. These panels have already found their way into popular devices such as the Galaxy Z Fold4, Galaxy Z Flip4, Galaxy S23 series, Galaxy Z Fold5, and Galaxy Z Flip5. Notably, Apple’s iPhone 14 Pro series from the previous year also features these advanced panels. Looking ahead, the upcoming entire iPhone 15 series is set to further showcase the prowess of Samsung Display’s M12 OLED material.
In a bid to cater to a diverse range of customers, Samsung has introduced the M13 OLED material. However, this material hasn’t yet been adopted by Samsung Electronics. Interestingly, speculation suggests that Google’s anticipated folding-screen phone might pioneer the use of M13 material.
In conclusion, Samsung Display’s relentless pursuit of cutting-edge technology continues to reshape the smartphone display landscape. The introduction of a low-refractive CPL overlay holds the promise of enhanced optical efficiency and a superior viewing experience. While challenges in production and cost lie ahead, the potential benefits are too compelling to ignore. As the industry eagerly awaits the unveiling of this groundbreaking innovation, the smartphone user experience stands on the brink of a remarkable transformation.
