Look ma, pretty lights
Ever drive by a Sonic or other business that has one of those large full-color video screens? You see how bright they are and maybe wonder how in the world they can be cost effective.
Let me show you one of the reasons they are¬†dissimilar¬†to the common house hold LCD, Plasma, or even LED TV’s.
The human eye is very tricky. Percived resolution is not as it seems. Look at a video billboard while driving and you think….. “it would be AWESOME to watch the Superbowl on that!”
Fact is, nope, it would stink. It is also the same reason a 720p TV looks just as good as a 1080p TV at 15 feet. The human eye cannot see that much detail as distance grows.
The picture today is an¬†up-close¬†shot of a Sonic video board, as you can see it is made up of Red, Green, and Blue leds. Big ones.
Before you jump on board with the new 1440p super-duper-HD coming down the pike, remember our ability to see the improved resolution is directly related to screen size and distance. I love my 50″ 720p Plasma, especially since we sit 15 feet away. For those wondering… Plasma is still the best image for flat-panel TV’s. Not as high of profit as their LED and LCD counterparts, so the marketing is skewed that direction.
More information on this may be found¬†here. Funny thing is, he is making the argument FOR higher resolutions, but look at the applications he is¬†describing¬†– not your average living room. For a home-theater, 1080p, 1440p, and beyond could really be mind blowing thanks to close seating and huge screens.
An amazing company called¬†RED is making motion picture cameras that shoot over 4000p – yea. What is amazing is current technology, even though 3x lower resolution, still benefits from super high def cameras – the images are just stunning. FYI… RED has a small Topeka office with super smart programmers working on the¬†back end¬†coding that makes these sweet machine tick. I am hoping to shoot some video someday on one of these amazing cameras.
