That's why Kiwi Semiconductor made the PCB's themselves... to dramatically demonstrate the area savings. (Also significant power savings at even better performance :-)
Kiwi is apparently at some show in Vegas this week showing off my work :-) ...Jim Thompson

Often it's not as much the 'concept' as it is the ability to build it. Take a gander at this: the first 'plasma TV'. And, for the time at least, 'big screen'.

How would you like to be the sucker stuck with hand wiring that thing?
Note down at the bottom a discussion about the hypothesized 'chin rest' that was, instead, for a telephone. Man, Bell has been trying to sell the idea of a 'video phone' for as long as I can remember and, apparently, long before I was even born. There it was 1927.
More Bell work

'Video phone' was featured as one of the whiz bang 'high tech' deals in the movie 2001, A Space Odyssey. Wow! Gasp! 1927 tech.
Btw, here (about half way down) they mention color television in 1929

Of course, you need a 'VCR'.

Prices may have increased since then but the Deforest 8 tube Television and Broadcast Receiver, down at the bottom, looks like one hell of a deal at $47.70. The seller is the 4 THOUSAND milliwatts of undistorted, non motor boating, humless audio.
But you still need a televisor so maybe the See All is a better deal. Depends on how much the tubes are.
"Huge"? I said tube, not mechanical. A bulb per pixel, without printed wiring, is going to be terrible, that much is obvious. In contrast, a proper tube reciever only needs maybe ten tubes for the whole thing (fifteen if you include RF/IF strip, and about double that for color decoding). NTSC TV is actually insanely simple to build, which is no coincidence as that's what they had to work with, back in the day.
Now, a security camera controller, Idunno. If it's just control loops and stuff, no big deal. Heck, they even used vidicons up until quite recently. If it's got a lot of digital decoding and encoding, that makes the solution exponentially more active-device-intensive, which still isn't bad in and of itself, but the difference is, transistors are printed, tubes are not.
Of course, regardless of the tube technology used (including recent field emission research), it's hard to match CMOS current consumption.

Hehe. Well, they did use tubes for transmission and reception. It's just the 'televisor' (and 'camera scanner') that's mechanical.
Well, that was the point and it's not so absurd a comparison as it might at first seem. The 'concept' is not significantly different than an LCD (or modern plasma) screen except, of course, you have to hand wire the matrix and individually manufacture the pixel elements.
Remember, my point was "Often it's not as much the 'concept' as it is the ability to build it."
As to your disdain of the 'mechanical', imagine doing the multiplexing with tubes. That's a lot more devices, and wiring, where a motor contactor is imminently simpler.
That is, as Dr. Daystrom said of the M5, "a whole new approach."
I find it fascinating how, sometimes, 'technology' goes in circles but certain approaches are dismissed based on a perception of what's 'high tech' at the moment. For example. 'digital' is 'the thing' today, right? Well, you can alter the impression by noting that multiplexed neon plasma picture was 'digital' while the CRT is analog. Which is the 'high tech'?
Even in the late 30's there were those who considered mechanical reproduction, various rotating mirror types, superior to the CRT because it could produce brighter and, so, potentially larger displays. 'Mechanical' did not have the automatic disparagement it later acquired; just like, today, we tend to assume digital is inherently superior to analog.
The death knell was the difficulty in keeping up with increased vertical line resolution.
Or was it? Lookie here.

Shazzam!. Guess what, a couple million MECHANICAL mirrors on a die. Mechanical TV is BACK! As the magician said: "it's done with mirrors!"
Back in the 1930's it would have been absurd to suggest building thousands, much less millions, of individually flapped mirrors when a handful of rotating ones could do the job just as well but it's silly to spin that many mirrors when you can make micro mirrors.
All a matter of being able to build it ;)
Of course, the originally 'high tech' CRT is now passe' compared to the multiplexed 'digital' pixel, just like that 1927 display.
Btw, the DLP "color wheel" (mechanical too) is reminiscent of the failed CBS "color wheel" in front of the CRT while the 'three chip' version is like early 3 CRT color systems.
Well, I see it from the other side. That was about as complex as one could practically make for less than astronomical prices and it only seems "insanely simple" to you because you have "insanely simple" manufacturing techniques to work with.
Remember, the basic NTSC concept, serialized video reconstructed with one form or the other of flying spot scanner, goes back to before there was any way to build one.
Right: a manufacturing technique.
Computers used to be tube too, you know, but you couldn't build them small, fast, or cheap enough for ridiculously complex things like that. Didn't stop people from imagining robots, though, or Buck Rogers flying around in what must have been at least a 12 megaton spaceship to carry all those tubes and the hydroelectric dam needed to power them.

That must be the ISC West, International Security Conference. Vicon is around the block from me, they had pretty impressive stuff. And that was 12 years ago.
5 weeks start-to-finish... circuit design that is. 2 weeks for my layout guy to generate GDSII for the mask set. Parts out of XFAB last week.
I know nothing about their board, or how they use it. I design from a spec. They sign off on a spec. If it don't work in their board, but meets their spec, too bad, so sad ;-) ...Jim Thompson

FYI, that chip is a trivial one... high volume consumer stuff.
Last November I finished another design, probably 20X the complexity of the Kiwi chip. It's still in layout, possibly done end of next week. ...Jim Thompson

All you can see there is a dull old chip package, how about a block diagram or something better illustrating what's inside and the chips functionality?
