back to article 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 …

      Even though I'm blind & no longer use one, I still remember fondly my old flat screen monitor. I'll doff my cap, lift my tankard, & buy the next round to help commemorate. Good job!

        While I don't remember Spear, I do remember LeComber as a genuinely nice guy as well as being a bright as they come. We were all shocked when he died so young (younger than myself now) and I even made it to his funeral service. RIP.

    Wonderful.

    Anyone know the reason why their patent failed?

    An excellent story, bravo.

      Re: Wonderful.

      In summary, the publication of their paper prior to the application made it easy for the competition to be first out the gate with the application.

      I think this court case may shed some light on it.

        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.

          "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.

        Joe, if you really make the grade, you could ask for a Tektronix 4010, perhaps?

    TFT patent?

    Anyone know why the team couldn't patent TFT?

    1. Mage Silver badge

      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.

          RCA name is on the digital terrestrial TV boxes here in Philippines.

          Don't know who owns it though.

          Probably a similar setup that Polaroid went through where the name was still a trusted brand no matter who was making the boxes.

      Re: TFT patent?

      Prior art. There were plenty of TFT papers published in the sixties.

      The real breakthrough with this work was getting the amorphous silicon to perform well enough. The older TFT designs used materials like Cadmium Selenide as the semiconductor.

    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.

      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.

      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.

      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.

    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.
