[QUOTE="skyliner2, post: 594695, member: 65697"] [b]AW: LED TVs[/b] Well, I think there are a few more things to say about LED TVs. Of course it are simple LCD-TVs with a different kind of backlight. Actually there a 2 types of LED-Backlight. Most common is the "sidelight". The LEDs are located at the side of the LCD Panel. Some (more expensive and thicker LED-TVs) use real LED BACKlight. In this case, a lot more LEDs are located behind the LCD Panel. Why? Well, one big advantage beside the lower power consumption of LED TVs is the better contrast. Okay, the contrast of the LCD panel is not better than in a common LCD TV. But LEDs are capable to dim. So they dim down when you watch a dark scene in a movie and light up in a bright scene. This makes you see a deeper black in dark scenes. At this point you see the difference between sidelight and backlight. Sidelight LEDs can only dim the backlight intensity for the whole image. So, of course, bright details in a dark scene get become darker, too. With a real LED backlight, only dark areas in dark scenes get dimmed. The LED's behind a bright spot in a dark scene stay bright. This gives you a really better contrast. Of course, there's a disadvantage, too: The backlight LEDs are connected and dimmed as clusters. So no single LED is dimmed or bright, but a cluster. So you will see some "glow" about small, bright objects in a dark background, if the object is smaller than the LED cluster behind it. At the moment, there is no backlight LED TV, which can control every single backlight led seperately according to the image displayed on the screen. IMHO, LED TV's are a good choice to save energy, especially at big screen sizes. But the better contrast they offer is nothing else than cheating your eyes. I'm waiting for the upcoming release of OLED-TV's. :) BTW, excuse my poor english, please. I'm out of practise :P [/QUOTE]
