ELI5: What's the difference between LCD, LED, and Plasma HDTV's?

I have no idea which one to really look at when buying a HDTV for Gaming & Netflix. They all look ok, but what's the difference?

**LCD - Liquid Crystal Display**

Behind every pixel on an LCD display is a set of RGB subpixels containing the liquid crystal cells. An electric current varies the amount of light the cell allows through, a color filter sets the cell as red green or blue. LCD's need a backlight, which is usually flourescent lamps.

**LED: Light Emitting Diode**

Any TV marked as LED is actually an LCD. The difference is the backlight, which uses a matrix of white LED's instead of standard bulbs. The advantage with an LED TV is that the amount of backlight can vary across the screen, increasing contrast and allowing deeper blacks

**Plasma**

Plasma TVs have each subpixel being it's own flouresent bulb, so there is no need for a backlight. Plasma had a bad reputation for "burn in" where a stationary image left on screen for a long time (like a game HUD) affected the subpixels and left a ghost image even when watching something else. Modern plasmas have technology to counteract this.

**OLED - Organic Light Emitting Diode**

OLED tvs are true LED TV's and work similar to Plasmas, in that each subpixel is an individual LED with no backlight.  Like a plamsa TV this allows rich colors and contrasts, but OLEDS can be printed at much higher reolution than Plasma TVs, allowing for 4K resolution, or more subpixels per pixel.
