Samsung receives a patent for a force-sensitive touchscreen display
Samsung has just received a new patent for a "touch display apparatus sensing touch force". The South Korean manufacturer states that although such force-sensing touchscreens already exist, most of them require a separate force-sensitive sensor, which unnecessarily increases the production costs of the dispay.

Samsung's solution, however, suggests that this additional sensor can be omitted, as the company intends to implement a tiny force-sensing processor into the display itself. This processor includes an electrode resistor and a reference resistor. Both of them are connected to several very thin layers of piezoresistive materials, either graphene or carbon nanotube, which have different resistances. These layers are situated inside the display.

Once you press your finger against the display, the layers provide the miniature on-display chip with feedback about the duration of the touch input. Then, the tiny processor determines whether "the touch is a soft touch or a hard touch". According to Samsung, no additional processing chips are necessary.

Yet, no one can tell when or if Sammy will implement this technology into its mobile devices.

Please dont jinx us and talk that back up. Soooo glad capacitive screens are the norm now. That almost made me dump my Omnia 1 and go to AT&T for the iPhone in 2009.

man i Had an Omnia1 too!! you too suffered the wrath or the resistance too?!?! welcome home Brother!, for the war we fought with our omnias were Real!! the camera was great!! sure!! 5megapxls in 2009!! in America!!! lols took better pics that the iphone!!! oh, an the Optical touchpad!! i know you were sold Too!!, once u saw that the "phone" had a laptop-like "mouse pad"!!! ANNDDD it was a touch screen!!! that ran Windows Pro!, not some crappy symbian OS!!! (android was nothing in 2009 ppl). it even had 8GB of storage ONBOARD!!!, and Still had Expandable memory to a 32GB SD card!!! even had a Google Maps Download...WITH Navagation!!! yea i thought this Omnia phone was an iphone Killer Too, but that damn RESISTIVE touch screen just got worse, and worse... and more worse.... n to the point i was stabbing the damn screen almost w/ the stylus. and ALSO it would like "save" all ur txt messages on the phones "internal" memory 0_o .....NOT the damn 8GB internal storage it came with. to the point it would fill up the memory with Txts n ur phone was so low on memory, it was Bricked practally!!! like this was the phones worst flaw honestly. o n the final nail was the "App store" wasnt that, more like a back alley where they would try n rob u blind with usles productivity apps that woulda sucked on the phone itself with all these other problems. so once sprint came out w/ 4G, i jumped of my shltty omnia to an EVO 4G. THAT phone was an iphone killer baby! (i live in Los Angeles County, so i Actually had, n still do have the 4G service) phone left me with such a bad taste for vzw i still havent paid my last bill from them LOOOOOLLLL!!!!! but they get the last laugh, kuz now i dont qualify to be Granfathered in for unlimited data any more on t that beautiful 4G LTE network they built D': ...oh well.

lol...Yea... It was so bad with my phone I could only type on my phone in landscape mode. The screen got messed up bad, fast. But I gave up on mine quick...I missed Google Maps or didnt know about it at the time. I tried so many hacks to get free GPS on my phone. I got the Droid 1 in early 2010 and havent looked back.

i almost bought an iphone back then, but its camera HAD NO FLASH back then, n also couldnt RUN FLASH on websites. so those two things kept me away from iphones. i might have been able to do w/out running flash online, but no Camera flash?? on a good as hell (at the time) camera the iphone had??? made NO sense whatsoever. apple has just always lagged behind tecnologicaly speaking with the field. they never get all the gud Tech shizzle in their phones in time. yea the google maps on the omnia, u had to go directly to googles compatability page n download the app from there. but....it was a wonderfull app!!! even with the shltty screen. mighta kept usin my omnia if the txt msg memory problem didnt exist. n android phones at the time of the G1, it looked like a glorified Sidekick (remember those?) which wasnt bad. but it was on T-mobile, Before t-mobile was bad ass. lol all my friends that had t-mobile were still "running out of minutes," so yea i was like g-h-e-t-t-o!!! lols, lil did i know how beautiful the app store would become. i mean, could u blame me?? do u REMEMber how bare the windows mobile app store was?? i thought surely "who would make apps for anything but an iphone?" thank the Lord i was wrong!!! low key....i still use the Omnia1 as a Back-up camera incase my actual camera dies......its that good!!

I could see this used in some games. Hard press on the screen for rockets, mild press for machine guns. If they can get different levels of sensitivity on the users touch. Then you could even make an on screen piano that responds with different levels of sound for each piano key that is hit.

I'm curious though, is this really better for the end user? I doubt end user will see a lesser costing phone. So?

Couldn't it make passwords more secure by introducing another variable?

Here's how I would like it to be used. I hate the fact that when I am typing on a touch screen, the moment I touch the screen, it registers the key I am pressing. What I would like to see is a light touch would show visually what key my finger is over and then a harder touch would register pressing the key.

exactly!!! its why i made the jump to touch screens so late. its also y i bought an Omnia 1 when it came out, kuz it was a resistive touch screen (see my previous post above for some laughs). also when the blackberry storm came out i was excited about that too, but it too was a major flop kuz of Major, MAJOR software bugs & glitches. the demo units in the vzw stores were so unusable, they would have probably sold more BB storms if they had Demo Dummy units out there. (god i hate those). so yea thats the one thing i hate most too about capactive, touch screens, but its the best we have 4 now.

"Oh no! Don't touch me! I'm too sensitive down there", said the phone.

This would be good for music production apps... Reminds me of velocity sensitive pads that drum machines have... .................... Come on Microsoft!!!

Ahhh I see. Yea...Samsung ....even tho I dont really like their phones....try to one up the competition with specs n features. Gotta give them props for that.

This would be good for under water use as traditional capacitive screens dont work underwater.as in the "touch" doesnt work underwater.
