- How do touchscreens work anyway? Johnson was the first to create touchscreen technology, these displays hadn't gained popularity till the 1970s, when the resistive touchscreen was accidentally invented. Further developing on that new technology, scientists at the University of Toronto invented the first multi-touch display in the 1980s. As for the very first touchscreen cell phones, they came out a little later in the 90s.

SUMMARY
The scientists needed to use some equipment that was so overworked that it was only available at night. You can imagine how much that inconvenience was slowing down their progress! It was then when Dr. Hurst and his colleagues thought of using some electrically conductive paper in their research. By developing this idea, they eventually created the first computer touchscreen ever!
What’s the magic behind the touchscreens we know and love today? If you thought that just one technology stands behind this "swipable" phenomenon of our time, think again! In fact, there are more than half a dozen approaches to make touchscreens work.
The technology is simple: you press on the screen hard enough, and it bends and resists your touch (hence the name). But what happens next? The thing is that a resistive screen consists of two layers that can conduct electricity.
Capacitive touch screens are made from either indium tin oxide or copper. Both these materials keep electrical charges in super-tiny wires, with each of them way thinner than a human hair.
Ever wondered why your cell phone won't respond when you're wearing gloves? The problem is that clothes don't conduct electricity (unless you have special gloves fitted with conductive threads of course!).
Most people don't realize just how widely used touchscreens are! In fact, nowadays it's hard to find a field that doesn’t make use of them. Airplanes, stores, banks, schools and universities, hospitals, you name it!

Thank you sooo much I was soo angry that I had to watch a whole 10 minute video for this......
Thanks bruh
Touchscreen’s are taken for granted
No
1000 subs without content do you think so?
Yes they are. Look up "what happens when you shred 20 i phones"or "putting smart phone in hydraulic press" then come back. So YES they are taken for granted
Everyone wish touch screen can touch twitch stuff at one time instead of one every time
Touchscreen's _whats_ are taken for granted (according to you), Rokunii? Which possessions of a touchscreen did you mean?
Fun fact: Touchscreens work when you touch the screen.

There was a touch screen in 1955 using a light pen. The first light pen was created around 1955 as part of the Whirlwind project at MIT. I also had a touch screen on my Commodore computer in the 80's it was a grid you clipped over the screen a bit like the infrared on demonstrated in your video.

I have to say I love your video's. They are so informative and that's what I love and so interesting. I am a big fan and thank you for all the video's that is posted. ❤❤❤❤
Incredible, I remember that I owned some phones in 2008/2009 which had plastic touch screens which needed calibration 😂 They had something like a thin plastic film which was pressed inside the LCD with a little bit of force in order to recognise the imput. Great techincal advance 🎉

More interesting and informative. Thank you bright side
Even before they became popular I was able to use touch screens regularly around 25 years ago. I was a child and my baby sitter also worked for a company that was completely perfecting the technology before releasing it and since I was super intelligent and had already built a really good computer I was used as a human test animal for many technology products before they became popular back then.
EA Johnson, he’s in the game.
😂😂
I get your joke
Bright side: explains things that we usually don’t think about😅☺️😁. Thank you!
Me pausing the video , taking a deep breath and thinking so all these happened when i paused it, i have super powers😂
I think I am the only one who was messing around with my screen😂😂
Brandon Ortiz why were you messing around with it?
BRIGHT SIDE because of the vid
yes you were
@@BRIGHTSIDEOFFICIAL u really asking?😂
I learn something new everyday from Bright side! 😊🇺🇸
Sincerely!
Learning this made my life more complicated.
When the first cell phones with touchscreens came out, the touchscreen was still some fancy technology and I thought most of these will show problems and will ultimately fail as a type of phone. Oh, boy was I wrong! :D
I remember when I touched the screen first time , felt like magic.
No…it was horrible 😂

Who else is fascinated and now touching your screen weirdly during the vid 😂
This is why i touch my screen and i clicked youtube and i see Bright side just uploaded a video and i clicked and this how touch screen works

Nice update bright side, keep up the good work
I’ve always been curious 😀❤️ Now I know 😉
Thank you so much BRIGHT SIDE for giving us such information.....
i was always told that resistive touch screens work with invisible lasers making a grid that goes underneath the screen, with one side being the emitter and the other side being a receiver. you press the screen and it disrupts the grid, and it can tell where you touched through that

What an idea can't wait to see what they come out with next
Holoparabolic projected imaging will replace tactile screens altogether, most likely.
I remember touchscreens before smartphones came along and they were just awful to use. That was one of the most amazing things when I first used an iPhone, just how responsive the screen was.

This is a very useful video for kids .I make my child see this channel sometimes and he really likes it and he tells that this channels videos are very funny and intresting. Thank you
Wow I didn't think of that
I always wonder how the touch screen works... this video really answer my curiosity
.... my device Im Commenting on doesn’t even have touchscreen
I remember seeing the first "touch screen" ATMs and noticed that what was actually there was a sheet with a grid of wires over the display. So the screen itself wasn't touch sensitive, just the overlay. Very basic but also very easy to control. It takes no more technology than you find in the average keyboard. Just an X/Y detection grid using a couple of micro controllers to read the key taps and then interrupts to transmit them to the main processor. It was kind of a cheat, but it served its purpose and USUALLY worked pretty well. However the grid spacing was fairly wide and that meant the wires were far enough apart and the distance from the overlay to the display was enough that it your eyes were too far off center (like looking down at an ATM display that isn't positioned right), you could sometimes press the wrong location because of the parallax.
U should of said one word
SENSORS

Its awesome.... Its pretty amazing as I was wandering this question quiet sometime now....nice video :) very informative
The title should be "simple words that last 10 minutes"
Thanks for this video of touch-screens., so there are various of touch-screens possible, which one is the best ?
Atoms that aren't neutral, they 're called ions!
Ions are positive only tho
@@infrakazos those are cations
@@atharvakapile8065 yep and negative are called anions.
Excellent presentation ..insightful indeed...!
*Nah its just my tablet that has feelings*
Yesterday I was thinking how touch screens today I check and boom I love you bright side❤
2:20
"i Guess they never miss huh"
Lol
Bro it’s summer but this video has wayyyy toooo many science
I just realised that technology is really advanced
marvelous inventions for mankind !!!
Sir, please replay my one question
1. When we inserting screen guard how does work? ( glass is act insulation or it's not cary electric charge)
gitesh patil the screen guard that we use nowadays is actually a really thin plastic sheet and I don’t think it has insulating power to completely eliminate the electrical impulse that you give out upon touching the screen.
@@hke.4475 insulation breakdown! capacitance is all about insulation property, if insulation breakdown occurs, there is no capacitance
This video is describing few things wrongly. Touch screens don't work this way.
Outstandingly done!
Panibagong kaalaman, salamat😍
Lol I don't know if it's a new approach but I found this video a lot funnier than the old ones, such cheesy jokes, yet I liked it :'D
Touchscreen actually tracks your Finger.
no
I'm old and my hands shake. As a result, the touch screen on my android must get confused. Phones need an "old people" mode.
I click this as fast as it came out and it already have 23 comments and lots of likes!
God save me XD
Love ur vids!
Really Helpful!!!
Thanks 👍👍👍
Actually it’s easy it’s the screen feeling your finger from heat and electricity from your body.
but how i press the screen with magnet
@Antony Ruiz i wrote that comment with magnet
I put finger 1 mm from the phone and it reacted
WELL DONE! U DID IT AGAIN BRIGHT SIDE!
PLS GIMME LIKES LOH YEH MOH YEH
Remember the calculator screen?
It had a strange smear-like effect when you point toward the screen with enough pressure contacted?
You were squeezing the Liquid crystal deforming the display
Did the liquid crystal help prevent condensation from happening?
What else was it about?
@@jonathansantos6009 the display was LCD and that stands for - Liquid Crystal Display when you pass a current through the liquid the crystals polarise making them visable. my calculator once froze in my bag and shattered the display.
Do you remember what temperature it was when your screen shattered?
Current or pressure?
What’s the inference?
Nice information 👍
That's mind-blowing....
Can I get a new mind?
Very useful video.
Exactly 10 mins and 01 seconds. To place unlimited ads. Nice nice.
10:00 only
Hats off bright side for ur hardwork
Touchscreen works when you touch the screen.
so cool.... Thank you so much...😁😁😁
I miss my old nokia now :(
Start at 2:38
From 0:00 to 2:38 there is only history
Am I the only one thinking that why we don’t get taught this in school ???
cb_ reeba what do u have TH-cam for?;)
@@BRIGHTSIDEOFFICIAL tbh I never really thought that but I'm trying talk about how the teachers be talking about listening then explaining in the most boringest ways like having u watched bright side or wat ??????
Very touchy video.. 😁😁
When your super early
And you dont know what to comment
Nokia developed multi touch resistive touch tech for cheap touch phones in India during 2011 and 2012.
Nokia Asha series.
3.5" resistive touch screens with 2 finger touch detection for zooming in and out of images.
Sold at around 60$ at that point of time.
People used to consider resistive vs capacitive screens 10 yrs ago.
Now its LCD vs LED.
What will be 10 yrs later??
Will screens be used ? Or holograms? Or laser projection with motion trackin with radar tech?
