Millions of tiny LEDs

LED TVs have been around for some time; the display is lit by LEDs at the sides or rear of the panel. The pixels themselves do not emit light. That's different with OLED TVs. The diodes (tiny lamps) in an OLED TV are all individual sources of light, eliminating the need for back-lighting. OLED screens are ultra-thin and more lightweight.

Because each diode can be turned on or off individually, black appears as pitch black, colours are more intense and details are crystal clear. The high contrast not only improves image quality but also enables a wider viewing angle, as none of the contrast is lost.
