Which of the following display technologies is self-emissive and therefore does NOT require a separate backlight to illuminate its pixels?
OLED
IPS LCD
TN LCD
Mini-LED LCD
Organic light-emitting diode (OLED) panels generate their own light when an electric current passes through organic compounds, so each pixel acts as its own light source. Because a dedicated backlight is unnecessary, OLED displays can achieve perfect blacks and very high contrast by turning individual pixels completely off. All other options listed-IPS LCD, TN LCD, and Mini-LED LCD-are forms of LCD technology that rely on an LED backlight shining through the liquid-crystal layer to create the image.
