The two main types of flat-screen TVs that consumers are buying today include:
LED:
LED TVs have LCD technology and a high-quality picture; they come in a variety of sizes from a number of manufacturers and have proven longevity.
OLED:
OLED TVs have self-illuminating pixels and don’t require a backlight. Their picture quality is superior to LED TVs, but OLED TVs are more expensive, made by fewer brands and come only in larger sizes. Because they are more recent introductions to the market, their durability is still unproven.
