While LED stands for ” light-emitting diodes”, OLED is “organic light-emitting diodes”. That means the super ability to produce both light and color from one diode when you turn the electricity. OLED TV doesn’t have a separate backlight That makes the OLED screens extremely thin, flexible, and sometimes rollable! Every pixel you see on the screen is a self-contained source of luminance and color, The screen display illuminated only the areas the should be bright and keep the dark areas dark that leads to a superb picture quality.
