1. LCDs that are LED back-lit are NOT top to bottom only; the LEDs are behind the screen, hence the name "back" lit. Both edge and back-lit LEDs ultimately pass the light through the LCD panel from behind. The difference between them is where the LEDs are mounted; along the edges or behind the panel. And yes, it is correct to refer to these TVs as LED because they ARE LED TVs, which brings me to your next point... 2. No. LED and OLED are not the same in that they work in different ways. Unlike LEDs which rely on edge or back lighting, OLED displays emit the light themselves. Those aren't even available for the consumer mass market beyond about 11 inches right now; we're talking about LED lit LCDs here, which yes, are referred to as LED TVs. 3. Edge-lit LED-LCD screens can be thinner than back-lit, but back-lit (also known as full-array) screens have far better local dimming and offer a much better contrast ratio. Most edge-lit models don't even feature local dimming (even some back-lit models don't). Ergo, back-lit with local dimming offers the best picture. |
1. well what were the top and bottom only models that first come out? I know people use to describe them as back-lit (perhaps they used wrong terminology) and the edge-lit models were considered better as they went all around the screen. I must admit that having a full array back-lit is fantastic.
2. I never said they were the same, I said OLED should be know as the true LED tvs, as they will be emitting the light thmselves. using LEDs to light up an LCD screen to me is still an LCD panel with better lighting tech.
