As you can see in the picture above, these things make up a touch screen. You have your LCD Display Layers, Glass Substrate, Non-conductive Separator Dots, Transparent Conductive Layer, and Flexible Transparent Surface. All of these things combine to make it easier for you to use your iPhone, or any phone with a touch screen.
Some phones use sensors and circuitry to monitor changes in the present state of the screen. Others, such as the iPhone, monitor electrical current changes to detect changes on the screen. Another way certain phones and other touch screen devices use, is the detection of waves such as sound waves or infrared light beams coming in contact with the phone. Other systems use transducers to measure changes in vibrations; these vibrations are detected when your fingers hit the screen. Some use cameras to look for changes in light.
Phones are very interesting things that help us in our everyday lives, now we know one more thing that helps them work. If you can find out anything else that you think is interesting about smart phone and the like, feel free to comment with your discoveries.
(I thank my findings to this website)
I was curious as to how sound waves coming in contact with the phone can change the phone?
ReplyDeleteI found out that vibrations in a phone are due to a stimulus, and the physics does the rest of the work. But I'm not so sure about it because I don't have a source.
Thats really cool I never knew that. It was also cool to know that the screen senses a change in vibration
ReplyDeleteEmily, that sounds like a reasonable reason why the sound waves would work. I wouldn't be able to come up with that without a source so I would say you're probably correct.
ReplyDeleteAnthony, yeah I thought it was cool too I have a touch screen phone so I always wondered how it worked exactly.
ReplyDeleteI never knew all that. I have been using touch screen phones for awhile now and I never got exactly how they worked.
ReplyDeleteIt's interesting to think about how something we do everyday really works. I mean, it's not like I actually sit there and go "I wonder what is going on inside my iPod as I touch these buttons." But it's cool to really actually think about it. I also never knew the makeup of a touch screen like the layers so that was interesting to see.
ReplyDeleteYeah when I read about this topic I was like wow that never crossed my mind!
