    Most importantly is to make it profitable. No one other than an handful of autists want CRTs.

      no one but a handful of autists would want shit like FPGA gaming consoles yet there's a market for those, probably similar autists that would get a brand new CRT. Hardest thing would be (apart from all the technical knowledge) the lead screens. Maybe somewhere with frick all environmental regulations but even the worst third world shitholes have them.

        Electronic boards are extremely easy to manufacture and all the parts you need are still in production. CRTs are extremely specialized, even the shipping makes them untenable since you gays can't rub more than $100 together. Even if you managed to make a specialized CRT production line each unit would be $5000+ and you'd have to expect to make at least 20,000 units. It would be cheaper and easier to simply spend time making software that properly emulated CRTs.

        Nothing about FPGA consoles is actually custom, it's all off-the-shelf hardware. That's why they're using FPGA chips in the first place.
        Compare that to CRTs where actual custom manufacturing on custom made lines in custom made facilities has to take place instead of just simple assembly.

        with an fpga console the only hard parts are the fpga and the software
        fpga's are used for many things, so such consoles use off-the-shelf fpga's, and the software anybody can work on using only their time
        with a crt, the hard part is the ... crt, the picture tube and electron gun, they are far from simple to manufacture, and you can't use off-the-shelf parts to make one, so they aren't comparable

    It's probably just way more expensive than the shit they pump out by the minute today. Also the market is niche and already cornered. A new wave of CRTs may appease the fanboys and collectors but you need a product people WANT. And people don't WANT heavy CRTs with lower resolutions than what LEDs and OLEDs and LCDs can produce. And what are the relative implicit and explicit costs of manufacturing and distribution?

    Whenever someone asks if CRT manufacturing could come back, show them this. A billion dollar factory, top of the line robotics, hundreds of employees all to make a product which is unequivocally inferior to today’s television sold exclusively to a niche market of retro game enthusiasts. It will never happen again. All the CRTs there are are all there’ll ever be.
    Even still, the few thousand total sales from Redditoids and IQfy incels won't cover it.
    You are making an inferior product for an extremely niche market.

        The weight and depth issue was fixed with flat screen crt but they never hit the market as they were demoed after the release of lcd. The market had already decided to move to lcd.

    no. nobody is interested in making them anymore. there's no demand for CRT. even old televisions' CRT screens will usually last long after every else has died around it so there's no huge demand for replacements to justify opening up a new enterprise to manufacture them. i wouldn't be surprised if someone does start making them again since it's not complicated to make them.

    Why make crt when OLED and lcd tech is getting very close to the same contrast and black level of crt?

    • 2 months ago
      Anonymous

      CRTs had pretty bad static contrast and the black level is worse than LCD if there's any sort of light in the room at all because the screen is grey and not black, so even if it doesn't light up it's still grey. They're only "black" in complete darkness, by which I mean not even having any other screen turned on in the room because that's enough for you to tell it's actually grey.

      crt is 0 response time, lcd are nowhere near that. The response time on paper isn't the actual response time. There is also the issue of ghosting. Crt at 60hz has less ghosting than lcd at 480hz

      CRTs did not support variable refresh rate and cannot run at high refresh rate and high resolution at the same time, so in practice you'd need to run much lower refresh rate than a modern screen to get close to the same resolution. Modern digital screens ARE slower in and of themselves but the CRT running with VSync and low refresh rate would seriously hurt the total system response time compared to high refresh rate with adaptive sync. I'm not sure you'd actually come out ahead, VSync hurts REALLY badly.

    CRT glass is full of lead
    RoHS and similar kills the new CRT manufacturing. Can't sell to EU, UK, California, China and a bunch of other places.

    • 2 months ago

      It doesn't, it just makes it more expensive.
      Only the rear glass is leaded, CRTs are made of two fused sections of glass, the rear bulb and the front glass screen.
      The front glass on color monitors is Barium glass, barium glass is MUCH more expensive than leaded glass, but is needed for the front to display color.
      Barium glass is fine under RoHS, etc.

      But a 21" CRT was already $2k new back in 2004, a fully barium glass 21" would have been $8-10k then, probably closer to $20k now, with the level of barium glass production of 2004 - but since we don't need it as much anymore, we don't make as much, so it's probably really closer to 100k.
      For a 21".

      It's dead and not coming back.

    Would it be difficult to start an egg-packaging plant? I hate our current monopoly but am not a multimillionaire

      You should write a program that starts at 1 chicken
      simulates the time needed for it to grow
      the nutrition it needs for one egg
      the time it needs to gestate and lay said egg
      shit you're fricked you actually needed a rooster to attempt fertilization.

      Okay, so, one chicken and a rooster.

        I think I can acquire the eggs themselves from our local menageries just fine. Our fortè would then be selling worm-free eggs by using better technology to screen them

            Make sure to buy some of the eggs that the egg packer buys so you can DIRECTLY compete, but it would basically come down to output. If the have a so-called monopoly then they probably have a scale of production large enough that competition may not be feasible. Where you may be able to spend $10,000 dollars a day on eggs they can spend $10,000 an hour on eggs. Unless you have some sort of gimmick or special service that warrants a higher price good fricking luck. Only commonfolk wank to pretty products. Industry, ie chefs and kitchens, will take any egg that isn't full of salmonella (and maybe worms?)

            Definitely, the friction of entry is probably what's keeping out competition in the first place. It's relatively small country and big companies have a history of pricedumping until their competitors die out. Other countries probably don't have problems with worms since they use antibiotics, but they're banned here

    no there's not enough demand for there to be a factory. You can make a cathode ray tube, by that i mean a device that shoots electrons(you should probably buy it because making a glass vacuum is hard in itself and so is the rest), you can 3d print a phosphorescent screen maybe with,well, phosphorescent filament. What that'd do (I think) is light up with a greenish hue. I don't know I think. Now listen. You're probably a former web dev. You have bad habits. That half ass approached works for some things. Mostly web dev. I implore everyone on this god forsaken board to read. a.fricking.book.

    There's a youtube channel of some company trying to restart production of nixie tubes, they had some moderate success but it took several years alone to make the glass consistently, think how difficult it would be to make a whole CRT.

    Ok, let's see.

    Security first. Warehouse for incoming and outgoing goods, storage area for all components. Next, an ACI or surface mount department which will also need a smaller stores for specialised components. ICT testing for each completed PCB. Main production line where the line monkeys assemble the screen, PCB, Speaker set, etc. (thankfully , you won't need to pay a monkey to smack the side of each completed set with a rubber hammer to see if the case is seated as this can be done by a robot). Quality check department. Office block for management. Canteen and toilet block. Oh, and a staff car park.

    Have I missed anything?

    Generally a what dedicated hobbyist can make in a home shop is ~100 years behind industry. and without industrial backing you need a prototype before a product. So like 5-10 years until we have someone making a crt in their garage for youtube views and another 5 years or so before very expensive Bespoke new crts start to come out of eastern europe.

    Starting with the assumption that you mean a crt factory that produces all the parts needed, perhaps with circuit boards/plastics made by a 3rd party,
    With $60 million you could get an all-in-one factory that can maybe produce 2,000 units a month. You need a glass foundry, vacuum tubes magnetrons screen apertures etc etc etc. plus the r&d and firmware programming to support the business.

    You'll ROI in like....30 years....if you can manage to sell those 2k units a month without fail.
