The tech you're reading these words on – you have two Dundee uni boffins to thank for that
Every time you use a smartphone, glance at your smart watch, fire up a computer, watch TV or endure a PowerPoint presentation, you experience a little bit of Dundee. The flat-panel technology we use in modern devices wasn't invented by megacorps in Japan or Silicon Valley but by a pair of academics in Scotland's fourth-largest …

Re: Wonderful.
Which goes to show where the patent process is broken. Unfortunately they created the physics behind the technology but the patent is for the process of creating the technology. As they had no process they had nothing to patent and by the time they worked out the process they'd given the Japanese enough time to work out and patent the process before they could.

That's because the Japanese make stuff.
The sad other side to this story is the fact that we don't.

Re: TFT patent?
They were not a large USA Corporation. Or Maybe German, Finnish or Asian.
Ironic that RCA was gone by 1976. The dregs bought by French Thomson. Now name may be owned by Nokia.
UK from 1850s to 1970s was brilliant at innovation. More rarely at comercialising. By 1960s most of the original UK Electronics had either been morphed to MOD contracts or run by bean counters with no vision. Acorn's ARM was really the only one that escaped the curse and only by giving up making, but licensing.
Thorn went downhill after Jules Thorn retired (and died not long after, he had a long reign).
Mullard was Philips by 1928. EMI (HMV etc) lost their way in 1970s. Ferranti, Plessey, GEC, Inmos, ICL, Ever Ready, Burndept, Vidor, Rank Radio (Bush / Murphy). Sinclair was a serial disaster, certainly a show man. Alan Sugar /Amstrad. The other UK companies in Telecoms & Computers.
Most Edison & RCA patents were bought in, intimidation, ignoring prior art, simply invalid etc. To and extent Bell Labs/AT&T (The UNIX land grab of work done by the Universities) Though all did innovate too.
The USPTO especially needs reformed.

Superb article!
Alistair, this is by far the best non-humorous article of yours that I’ve read. It is a shame that the monument is posthumous, but at least it gives hope to other unsung heroes and will be greatly appreciated by their families. I really appreciated the factual and historical content.
Thanks too for, as usual, producing an article that isn’t full of typos, schoolboy errors and grammatical mistakes. All in all a wonderful (late) breakfast read.

FTFY.
(Seriously, it's amazing quite how prolific the Scottish are at coming up with cool stuff).

Except that neither or the inventors in this case were themselves Scottish, and nor did Alistair actually claim that in the original wording.
The discovery was made at the University of Dundee, but Walter Spear was German, and Peter LeComber was English. They first met and worked together in Leicester and LeComber followed Spear to Dundee in the late 1960s.

TV
Baird didn't invent TV. He was an entrepreneur promoting an updated mechanical system proposed by Nipkow. https://en.wikipedia.org/wiki/Paul_Gottlieb_Nipkow Electronic TV was proposed in 1906 and working versions developed by others, though Baird's nearly instant film to electronic transmission was used in satellites to have high resolution and low data rate. From the beginning the problem was how to make the camera target. The CRT already existed and was the obvious thing to use as part of a camera, not just the display.
Farnsworth didn't invent TV either. His system was technological dead end. The big problem was viable electronic camera. EMI/RCA collaboration based on Vladimir Kosma Zworykin's work started at Westinghouse in 1929.

Funny you should mention Baird but I wrote about him with respect to another IEEE Milestone bronze plaque last year: https://www.theregister.co.uk/2017/01/30/john_logie_baird_bronze_plaque/

Another notable contribution comes from the Stevenson family, famed builders of lighthouses, bridges, harbours, dredgers of estuary channels, they really pushed the science of civil engineering along. There's even Stevenson inspired lighthouses in Japan, such as this still functioning one. Even the lighthouse keeper's house looks like it belongs in Scotland.
One of the saddest episodes was the failure of the Scottish ship yards to adopt block construction, at a time when they were still profitable post WW2, preferring to stick with the old fashioned way. Now the Japanese, Koreans, Chinese, etc dominate ship building using block construction, and the Clyde is a shadow of its former self. It's a most painful lesson; Develop, or Die.

Re: Another British invention making money for elsewhere
Public key encryption.
Another British invention (right down to discovering the algorithm that was later rediscovered as RSA). It is only officially commemorated by an IEEE plaque at GCHQ to James Ellis, Clifford Cocks and Malcolm Williamson. Ellis died before the plaque was unveiled, and indeed before the government agreed their contribution could be made public.

Re: Knighthoods all round!
I posted almost exactly the same response, then deleted it after realising it (broadly) made sense- they're saying it took place too far away from the mainstream media (based in the up-its-own-arse centre of the universe, AKA London) and that the people involved weren't self-promoting or greedy enough.

Spear
> Walter Spear was born in Frankfurt in 1921 but his father, being Jewish, moved the family to London in the nick of time in 1938
Damn immigrants, coming over here, inventing world-changing technologies, become a Fellow of the Royal Society, blah blah

Otto Frisch too, who founded Laser-Scan, which worked with RSRE on liquid crystal displays (see my earlier post).

RSRE and Laser-Scan
RSRE (as it had become by the early 80's) and Laser-Scan in Cambridge worked on an alternative to individually driven LCD pixels, by drawing vector graphics using an infra-red laser to switch the phase of the LCD.
Reference to 1984 paper: Laser-Addressed Liquid Crystal Displays
I can still remember the goggles, locked doors and notice: "Do not stare into laser beam with remaining eye".

Re: I was going to say "how do you know I'm reading this on TFT?"
Definitely window size of browser. Not sure if total screen resolution is reported, but the technology of screen is not at all reported by the browser. They didn't envisage eInk (no animation and really you want to refresh entire page, not part) or mechanical pins for touch/blind(VERY slow) when deciding what browsers report. Even alt text is often useless.
A few folks using OLED (smaller screens but TFT too). Hardly ANYONE actual real LEDs (OLED are not proper LEDs), some CRTs still. I had an orange plasma transportable "laptop" once. The tech of choice for robust. Colour Plasma never really caught on for PCs/Laptops. Not many people using DLP (insane tech) projectors for web.
Most are using colour LCD TFT. OLED also uses TFT for the same reasons!

So where were CRTs heading?
Back in '75 or '76 there was a commercial exhibition in Hong Kong showcasing the developments in CRT technology.
The Japanese companies were showing small (approx 5 inch) CRTs without the shadowmask, but instead had extra phosphor index stripes that registered the beam as it passed over.
The feedback pulses from the index stripes controlled an RGB switch so that the beam was correct for each of the three colours generated.
They were touted as the future for projection TVs with the extra brightness and reduced heat generated.
So without LCD we could still be using CRTs.

Rate this article: 10 out of 10.
"With seven bar patterns per number, you only need 28 connections; add a few other things on the watch display and you still only come to around 50. "
Honourable mention surely needed here for charlieplexing, which allows creative use of circuit design to massively reduce the number of pins needed to control a display e.g. 10 pins for a 90-element display.

Other than that: which adverts do I have to click on to most effectively help fund more articles like this, and the Geek's Guide?
Sorry, 'social media likes' are not now (and have never been, and never will be) an option for some people.
