Samsung Display announced that its latest 90Hz and 120Hz Smartphone AMOLED displays were certified by Swiss-based SGS (Société Générale de Surveillance) to be "Seamless" displays. It seems as if SDC brands these OLEDs as Seamless OLED (90hz) and Seamless Pro OLED (120Hz).
Such high refresh OLEDs are gaining in popularity for high-end smartphones, as they deliver better gaming and video experience. SDC's 90Hz OLEDs feature blue length (image drag) of less than 0.9 mm (0.7 for the 120Hz OLEDs) and a response speed (MPRT) of less than 14 ms (11 ms for the 120Hz OLEDs). Samsung says these are the best specifications in the industry.
