As far as I am aware, the OLED is a TV with a curve to it. And the 4K TV just simply has 4 times the quality of a normal HDTV.

kg7or nailed it on the head. I'll just add some food for thought. You are buying for today - you need to keep that in mind. Modern televisions aren't the long life item they used to be, so there is no reason to plan on what is going to be the best set in 5 years when you'll be lucky if your new set lasts 5 years without repair, and most sets aren't repairable. Simple example. I like plasma as I main watch movies in the evening. I am not going to hold out for an OLED set if my plasma set fails. I will buy another plasma set. In 5 years if that plasma set fails, then I will likely (at the rate of change) be buying an OLED set. By then, we will likely be viewing 4K content, but right now we are in a 2K world with the best source.

A familiar 1080p screen is an LCD panel having approximately 2 million pixels. The term "1080" refers to the number of horizontal rows of pixels. A "4K" screen is essentially the same type of LCD panel, except that it has approximately 8 million pixels. The term "4K" comes from the number of pixels on each horizontal row; a bit under 4000. An LCD panel does not illuminate by itself. It's illuminated from behind by a fluorescent lamp in older or cheaper TVs, or by an array of light emitting diodes (LEDs) in so-called "LED" TVs. With an OLED screen, the pixels themselves are LEDs; hence the screen provides its own illumination. OLED TVs are on the market now, but they are very expensive and the screens in the earliest models didn't last long. It's too soon to determine if that fault has been fully resolved. 4K TVs are on the market also, but there is very little 4K program content for them--next to none. Even when fully deployed and implemented, you will be restricted to watching video from some type of media box (disk player, etc., like Blu-ray for 1080p) because you can't send 4K over TV channels. (That's even true today with 1080p.)
