How Touchscreen Works In Simple Words

- 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!

Ok?
So???
Yup
What you came for is 3:20
Thank me later.
thx
Fork you.
Thanks
Thank you sooo much I was soo angry that I had to watch a whole 10 minute video for this......
Thanks bruh
Fun fact: Touchscreens work when you touch the screen.
Whoah, new breed discovered. Humans finally evolved

Ohh thank you soo much!!! You simplified a whole complex concept in just 7 words!! 😑😑
More interesting and informative. Thank you bright side
Nice video, Bright Side, thanks!
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. ❤❤❤❤
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?
How touch screen works
Pretty Easy👌
Touch the screen and see how it works😎
Yeah that's easy but somehow crazy 😂😂😂
Here when you only have 34 likes😂
Thanks for telling
TECHNOLOGY WIZARD thanks for telling me, and you're a wizard.
No surprise your name is TECHNOLOGY WIZARD
Its awesome.... Its pretty amazing as I was wandering this question quiet sometime now....nice video :) very informative
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.

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 🎉
TH-cam recommends me this after 1year😂😂😂
Thank you
you really know how to deliver informations as easy as this one.
Wow. I'm learning a lot of new things from this channel!
You are the most authentic channel, whom I can rely on 💡.
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.
How do yo make fascinating videos everytime ? It's just amazing!!!
Outstandingly done!
my teacher made me watch this
EA Johnson, he’s in the game.
😂😂
I get your joke
Nice update bright side, keep up the good work
Thanks for this video bro!
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
Learning this made my life more complicated.
Thank you so much BRIGHT SIDE for giving us such information.....
What an idea can't wait to see what they come out with next
Always wanted this video. Was on my brain for 2 years. And now I know how this works. Thanks a lot BRIGHT SIDE 😉😊😘

Been thinking about this lately! Thank you
Bright side: explains things that we usually don’t think about😅☺️😁. Thank you!
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
Very easy colum row system with touch sensitive.
That was an amazing invention 🥰Thanks to Johnson Sir
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 😂
Am I the only one who now press on its screen?
Yea

Me pausing the video , taking a deep breath and thinking so all these happened when i paused it, i have super powers😂
Thanks for this video of touch-screens., so there are various of touch-screens possible, which one is the best ?
I somehow felt this was the reason of the capacitive touch screen. Because once I touched my screen with a dry cloth, it didn't work, but I used the same cloth but damp, and *it worked.*
Atoms that aren't neutral, they 're called ions!
Ions are positive only tho
@@sandpaperunderthetable6708 those are cations
@@atharvakapile8065 yep and negative are called anions.

Excellent Research
I like how this guy speaks .. he is amazing
I love technology but this video “ surprised me the most”
Jiji did you find it helpful?
It did thank you very much! I just wish I had someone to talk to but this videos answer almost all of my questions!
@@BRIGHTSIDEOFFICIAL i did ....
ps how do i suggest video ideas
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.
Now that the info we need
Thank you! ❤
Touch screen was created in 1965
People in 1964:
How do we do this with hand? We dont like keyboard
.... my device Im Commenting on doesn’t even have touchscreen
wew nice information i got here thanks, i think touch screen just have one type (infrared) but now i know theres many other types
Very useful video.

Nice information 👍
I have Been pocking on this screen since I heard this . It's pretty awsome

*YES EARLY!!!*
*LOVE UR CHANNAL!!!*
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.
Bright side, as always, you have useful information, but the sound of the music is louder than the speaker. I hear him confusingly. THANK YOU BRIGHT SIDE !
The title should be "simple words that last 10 minutes"
*Nah its just my tablet that has feelings*
marvelous inventions for mankind !!!
I always wondered how this worked
Touchscreen actually tracks your Finger.
no
I’ve always been curious 😀❤️ Now I know 😉
Hats off bright side for ur hardwork
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

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?
so cool.... Thank you so much...😁😁😁
Loved and 'Liked 👍' this vedio. 🤓
