UHD TV qu's

Some questions I'd like to have the answers to, if you would not mind?
1. Would you say the Number of pixels (for want of better word) per square inch on a LARGE 52" UHD TV are the same as a HD 1080P 21" TV ?
2. How does a DVD playback look on a UHD TV ? My collection is on DVD not Bluray.
3. On an OLED TV the pixels light up themselves right? There is no neon tubes behind the screen. How to they do that (light up themselves)?
4. Is therefore the power consumption of an OLED less than a 4K because there are no neon tubes?

1. http://kingscalculator.com/en/other-calculators/pixel-density-calculator
2. Depends on how good the upscale algorithms are.

3. Similar way a bulb does, converts electrical energy into photons.
4. Yes because you are only lighting up the dots you need, CCFL tubes are permanently on, LED vs OLED is different.

CCFL tubes are not filled with neon.
