High Dynamic Range (HDR) is now entering the market, traditional light emitting diode (LED) TVs are benefiting from the extra performance. If you watch movies with the lights off HDR is fine, but the best HDR-equipped full back lit LED TVs can also look good in a bright room.
Among LED TVs, there are two backlight types: Direct LED (full-array) where a large back-light shines through the whole screen, and edge-lit where lights emit from the edges.
Organic light emitting diode (OLED) TVs tend to shine, especially when the lights are off. This is because every pixel emits its own light. OLED is still the best, but if you want a TV above 65 inches you likely will be choosing an LED TV, unless you have a spare $30,000, which is the current cost of large OLED TVs.
