What do you think, how difficult and most importantly expensive is it to make at least one working LCD pixel from Nokia 3310 display?
As a kid growing up in the 80's I can't tell you how many LCD screens I pulled apart trying to see how they worked, but the only thing I discovered was how mad my dad got when I pulled his favourite lcd calculator apart. 😂
@MichaelKingsfordGray How exactly does that make me a liar? Show me where it's written that I have to use my first or last name to watch or reply to a bloody KZhead video? The ONLY reason why you'd want my last name is for nefarious purposes. If you want to put your full name up for the world to see, well good for f***** you! I've dealt with enough identity theves and hackers to know better than to post my personal details for the world to see. 🇦🇺
Was one of them using a DSM LCD instead of a TN LCD?
@@HeavenlyNovae I was a kid, the only thing I knew was the pixies went in one way and numbers came out the other.
@@johno9507 pixies?
@TheAutisticTech Yeah...the electrical pixies that come out of a battery. 😉 (It's a silly name for electrons 🙂)
Nice work! I'm really glad you were able to make your own diy LCD. Was the problem with the initial build the power supply (DC vs AC) or something else?
I think the problem was in my photoresist, which I used as a layer for making scratches on glass. When I substituted it with a PVA, it began to work.
@@Thoisoi2 Good Afternoon can I ask question I want know about( Red Sulfur) and (Yellow Sulfur) can you explain to me what they are. Thanks
@@Thoisoi2 up next, an LCD mask resin 3D printer! PLS
How much would this cost without the expensive signal gen? I'd like to try it with an Arduino.
@@JohnDuthie subtract 300€ by 250€ for the signal gen 😇
Never have I ever thought of this question but now I want to know the answer😂 Also huge hit of nostalgia from the Nokia 3310 asteroid
My first phone. Never knew it’s “proper” name. Nostalgia hits so hard and primal I wonder how it evolved
Many thanks for the hint on that DIY centrifuge. Simple and practical!
You cant beat Slavs at improvising
@@srksii No shit, our entire countries are improvisations!
Spincoater
@@rockytom5889 I'll let you know when I decide I should laugh or cry about my own country. Maybe I'll just improvise on it... Cheers from Portugal
I’m really glad to see this! We did this back in 2010 in college with very little info! before we figured out using a thin coating over ITO slides we tried to use tape, glass, plastic wrap, two slides, 10Kv through a full slide etc! Finally we figured it out using thinned clear nail polish! Ours was trash tho because we didn’t think about a spin coater! But it’s really awesome to start from nearly scratch and figure things out yourself this was one of the most rewarding projects I have ever been apart of! We even won a contest at a conference!
In 2010 your research into LCD crystals would (likely) have been more fruitful in the library, rather than the laboratory, because the device had already been mass produced. I do appreciate that there are trade secrets and the info would not always be readily available.
Also they used laminated conductive rubber strips to easily align the tiny power connectors in watches an $1- stick-on clocks.
Can't you just sandwich the glass, the LCD liquid, then another layer of glass, and crush it with some weight? Wouldn't that work? Another method apparently is to use microscopic glass beads between the 2 glass sheets.
What college did you go to? I would like to make my own LCD!
I thought it said “Homemade LSD cost” My bad, carry on.
if only
Hamilton Morris crossover episode time
I thought I saw the same thing at first glance. Thats not hard info to get lol. It also can be sold for more though so ya kno....
Oh well, the search continues
Same
7:00 shout out to Ben from Applied Science, he’s a rockstar!
Notice the end credits. Ben is a Patreon.
@@jimurrata6785 Ben is awesome all around, no surprise.
Fantastic video! This sort of video is why I love chemistry so much. Beyond the theory and applying it to something interesting and useful everyone can relate to (maybe of a certain age in regards to that particular phone) but as a kid I loved pressing hard on the LCD screen wondering what it was. So this made it clear as well learning well beyond. Thank you!! Спасибо!!
I still have one of those Nokias in my personal museum. Last month I've tested it and its battery still accepts charge. And yes, I played the Snake!
They truly are the toughest phone ever made!
@@chemistryofquestionablequa6252 Yes, they can only be destroyed in Mordor!
Nokia original battery is amazing, i syill have 5 BL5C
Fascinating video !! and consummately satisfying !! You teach me something interesting every time...thank you. im starting to feel chemistry is as mind bending as physics and more, and now i must know more of it,and you do such a great job showing it in its full glory , from all angles, clear back to who discovered it. the how and the why of things is so important to me!!!
Only scientists like you provide most accurate and useful information, thanks for your efforts.
Knowing how to provide sufficient info is an art that some people have not mastered. Sometimes, I follow instructions for setting up something for Linux, for compiling a project, for solving some technical issue and quite often, steps are missing. When it comes to chemistry, some of the video makers skip over details.
I really love diy electronic components! You help to demystify the otherwise opaque world around us. Thank you so much.
Thank you for your content! Greetings from Bulgaria!
Thank you for sharing your knowledge - love from the UK!
Great job man!!i asked myself for all my school time how polarized sheet and lcd work in calculators, i disassembled many calculators just for fun and i never understood how theese work, till now. Thank you a lot!
Exceptional. These efforts of presentation and explanation are highly appreciated.
Great in depth details on the evolution of the LCD! 🙂
Amazing! Great job and spectacular results :)
Very useful to learn such detailed notes of science that otherwise seems to be a secret. Also, I give you my appreciation for finding an MIT document in this topic, I have never thought that was possible. Best regard.
You're a great educator. Thanks for your contribution to science.
Cool. Have you thought of doing a video explaining LEL and HEL of petroleum? Through these experiments you could calculate how much fuel is required in a engine cylinder and calculate/ show the efficiency of engines - why they are so inefficient.
Gordon Freeman did indeed graduate from MIT. He's a pretty big deal these days.
Good choice of chems 👍 I love doing experiments with Sigma stuff 😋 always reliable for good experimental results. Greetings from Germany 🇩🇪
OOOOOOOO!!! Perfect Privacy Screen! Strip off the top polarize layer as shown, then only someone with Polarized Glasses can view the Display! You're a Genius!
Very cool! Thanks for the great content!
Great video as usual!
Amazing presentation, congratulations! Also love your home made centrifuge :D
Your projects are going crazy!
Very interesting! Thank you.
I never understood how these types of displays worked until I watched this XD Thx for satisfying my brain :>
I like the DIY centrifuge!!! .........and the rest of the video! Nicely done! & the 1/2 life ref# @ 13:17....that took a second to hit me!
Wish they were more like you you are one of a kind.
Very nice man. This is awesome.
I now know why when the screen breaks it get filled with black liquid. This is the best video you have ever made and most valuable video on YT. ☝️😌
Could you imagine "Cruelty Free, Italian Made, Hand Crafted LCD"
@MichaelKingsfordGray Why would I?
Hail to THE CHEMIST KING! Love your videos!
A good knowledge shareing. Good luck
Power supply should run -6V to +6V because a DC bias from 0V will allow ion transport. Place tape over the indium tin oxide where the electric signal is (alligator clips) before the polymer spin coat and remove after buffing so the ITO makes a good contact. Super glue and many other glues with catalysts and accelerators for cross-linking polymers contaminates liquid crystals with ions so try thermoset or thermoplastic adhesives. Liquid crystal should be free of oxygen, water and salts for best performance. Liquid crystal is also more expensive than gold by weight, as you noticed. Liked your video! Thank you.
I don't know about science but this is awsome! You are the good scientist! From Indonesia!
It's really cool how you do these in more than one language.
I'm always learning from u🤗
Amazing, good show!
the 1 phone that never breaks
Excellent video, I really enjoyed that. I was born before they came out and now look at them and other technology. The snow ball has started rolling… =]
Thank you, great video
Amazing video! Thumbs up!
Hmm, looking at 16:48, it appears that as the LCs align (at the rise of the square wave) they not only cause the liquid to move, but they also push the glass panes, forcing them to flex. The relaxation of this flex then pushes back onto the LCs, disrupting their order; it's only the fast rise of the square wave that triggers enough impulse to overcome the pressure of the glass. Rocky Robinson below points out that, in the industry, they use glass beads to force separation between the panes of glass. This would reduce/eliminate any constant, uneven pressure on the LCs, and the tension in the glass would be eliminated. It'd be interesting to see if this could be described with an altered Ising lattice model. There would be three factors: Temperature, pressure, and applied voltage, where the latter has uneven splotches, like a smooth Voronoi pattern. Higher temperatures and steep pressure gradients would cause the individual crystals to stray from the alignment induced by the voltage (randomly). Maybe I'll throw this together sometime this week and see what kind of patterns arise as a result :D
im glad this alien has decided to teach us the secrets of the universe.
Respect brother, greetings from Tanzania
That was really AWESOME
Remarkable for a DIY setup !
glad to see no bs videos, very neat
So glad to see you back online!
Back from what? He’s been here the whole time. He makes his Russian videos first, then dubs them in English for this channel.
Great video!
Congratulations! Your video is fantastic! I really wonder how do they physically wire so many pixels on screens without actually using wires. I have taken apart monitors but haven't seen cables at all. I guess they somehow multiplex the output for all these pixels nowadays? Must be a nightmare...!
nice vid dude!
Keep up the good work. One day everything could be made at home
This reminds me of algebra in school. The variance between this pixel and the screen on my phone that I am watching the pixel on, is like what you learn in algebra class compared to the test.
It works!! Bravo!!
T.Y. for describing such specialised field of application. And by the way - Applied Science has entered the chat 👍
fascinating!
13:14 I love how the most famous scientist to graduate from MIT is Gordon Freeman.
It is Howard Wollowitz, M.Sc.
Beware pure crystals
Loved the DIY centrifuge.
Really nice.
A half life reference? Stellar.
Indeed
congratulations!!
I'm thinking you could knock the cost down by omitting the dedicated frequency generator and instead drive the display using an oldschool 555 oscillator fed into a simple amplifier, maybe with an extra comparator or two thrown in to make the signal transitions faster. You could similarly use a computer's sound card as the signal source for the ~20Hz to ~22KHz range, and feed that into your amplifier to get your desired voltage.
finally, an LCD screen where the resolution, refresh rate, response time, and colour depth can all be measured as 1. The "perfect" display 😄
ultimate unity
Awesome bro 👍👍👍👍👍👍
nice you recovered your channel
Good job.
IPhone 11: Falls on the floor screen breaks! Nokia 3310: Falls on floor breaks floor!
I'mma make my own comically large calculator
Don't forget, you have to make the CPU using valves.
Awesome. I like your English accent
Awesome you are the best
Remembered about crystals when readig my old IT book yesterday. Today I see this!!!!!😆😆😆😆👍
Dude you are the best
Most LCD screens are IPS panels nowadays, but there are other kinds, for instance TN or VA.
Thanks , Ma friend!
Interesting!
beautiful
Great !
Thanks
glad that one of the best chemistry channels is back!
He didn't go anywhere. We just have a lag time between his Russian videos and the English dubs. His main channel is active as usual.
Wow, the engineering behind making an LCD is actually pretty neat :D Now make a multichrome one!
I mean. that would just require 2 more pixels and color filters. thats it. oh. and a backlight
Would love to see a gameboy screen at that scale.
I'd like to thank you for picking up the slack of Canada's science education system and teaching me something new today.
Awesome display
13:10 was the most profound, he has ever got. It was interesting to see a demo over how crystal screens became obsolete. LED, is already a nuiesence, we tried creating a non-optical screen, which only a night light would've required in dark, it looked like a color glossy prescription magazine, that animated like a video, too many of the expense and material got damaged or lost before illustrated. Could've been a power saver and no optic burdon revolution. Perhaps this host could try.
Nice to see you back online, explaining science, to students. Much appreciated - I trust your videos will start an enquiring mind or two, to explore chemistry & it's related fields, and generate, a 'new to science' application. Namaste 🙏 💟
Спасибо
This guy is a living genius.
Everyone: glue Thoisoi: zzhhglue kha kha khaaaa ;)
Good Job! Now here are the next challenges: 1. Create your own LCD screen [ / ] 2. Program it to adjust brightness [ ] 3. Make the display change to different colors [ ] 4. Make it touch-sensitive [ ] 5. Create an image using multiple LCD [ ] 6. Display motion pictures [ ] 7. Create a simple game using the display [ ] 8. Now test for heat and water resistance [ ] 9. Bend test [ ] 10. Samsung approval [ ] Congratulation in advance!
Step 2 is get enough funding for the next steps
Hello, I would like to ask about the previous video. in which you mixed cholesterol derivatives to arrive at a liquid crystal at different temperatures. Can you kindly refer me to that older video of yours?
I am still very interested in a reply to this.
What is the colourful thing in the display case? Different metal oxydation phases?
8:50 worlds best centrifuge 🤣
I am glad Thoisoi got his acc back. And came with amazing experiment too! Great!
Wtf are you talking about?
Super
where in the heck did you get a signal generator and end up with a 300 eur bill? also, like some other guy already said...the centrifuge is a really nice and effective looking DIY solution. many thanks, if i ever need one!
