Televisions based on Organic Light Emitting Diode display technology are fundamentally different from LCD TVs. The most basic difference is that each pixel provides its own illumination, while all of the pixels in an LCD TV are illuminated by an LED backlight. That difference leads to all kinds of picture quality effects, some of which favor LCD, but most of which benefit OLED.
Sorry, there was a problem. Please try again later.LCD = Fluorescent bulb backlighting. A fluorescent bulb behind the screen illuminates the picture. Blacks look gray and dark scenes suffer on this type of TV. The pixels on the screen produce the images and color. The bulb produces the lighting. This means that in areas of the screen where the image is supposed to be black, you get a gray from the bleed of the bulb producing light in the background. LED = Still an LCD TV but with LED backlighting, instead of a fluorescent bulb. The pixels still produce the images and color. Better than a plain old LCD because the LED's have much better control over the amount of light produced for each picture and some models can limit the light in dark scenes to just a particular area of the screen so that black areas are closer to the black level that was intended. There are many different types of LED TVs due to the different lighting technologies used such as full-array dimming where the TV can shut off light to different parts of the screen for better dark scenes. There's edge-lit where the LEDs are placed around the outside edge of the tv. Flashlighting and cloudy images are still a problem. OLED = The pixels generate light when producing the image and color. Where there is supposed to be light and color, the pixel creates it. Where there isn't supposed to be any light or color, the pixel shuts off. That means that there is no bleed from a backlighting source and you get much better contrast as close to the way the picture was meant to be seen as possible. Blacks are truly black on an OLED TV and not the cloudy gray that plagued LCD and LED TVs. No more flashlighting. A 4K OLED TV is truly as good as it gets. Other than owning your own movie theater.
Sorry, there was a problem. Please try again later.From a users perspective (I am a user not a techie) The OLED gives you more definition in the blacks and a truer looking color. The black difference give the picture more depth and the color looks more real. The LED is a much brighter picture darn good in the blacks and often a harsher less real color. I chose the OLED but, went back and forth till I saw the same picture on the two different scenes.
