OLED displays use a backlight to illuminate their pixels.
False
True
OLED displays are known for their ability to emit light without the need for a backlight. Unlike LCD screens, which do use a backlight to illuminate their pixels, OLED screens have organic compounds that emit light when an electric current is applied. This allows for deeper blacks and more contrast because each pixel can be turned off completely rather than just being blocked by a liquid crystal.
