A:AnswerGolferJim - The QN90D is a Neo QLED TV that uses Mini LED backlighting for hyper-focused brightness and dimming in all the right areas. The S90D is an OLED (Organic Light-Emitting Diode) TV that uses self-lit pixels to control colors of individual pixels to create life-like colors. It also allows the TV to turn individual pixels on and off to create deep blacks for incredible contrast when viewing HDR content.
