Keeb kwm luv luv ntawm Capacitive Touchscreen Technology

Kov npo yog hom HMI (Human Machine Interface). Ua ntej 2007, tsis muaj coob tus neeg tau mloog nws. Tab sis tom qab xyoo 2007, kov vaj huam sib luag tau siv txhua yam ntawm cov xov tooj ntse thiab ntsiav tshuaj, nws tau dhau los ua lub npe tsev neeg. Cia wb tham me ntsis txog nws zaj dab neeg tsis ntev los no ua ntej.

Kov npo keeb kwm - koj yuav tsum paub dab tsi?

Nws tsis pub leejtwg paub tias Steve Jobs muaj kev cuam tshuam loj heev rau lub ntiaj teb ntawm kev siv thev naus laus zis, tab sis tej zaum nws cov keeb kwm yuav muaj txiaj ntsig zoo tshaj plaws hauv xov tooj. Txawm hais tias lub xov tooj smartphone, nws ua haujlwm li nws ua tam sim no vim tias rov qab rau xyoo 2007 Steve Jobs sawv ntawm ib theem ua ntej cov neeg sau xov xwm thiab hais tias, "Leej twg xav tau lub ntsej muag? ... Yuck!".Apple tsis yog thawj lub tuam txhab uas tsim lub vijtsam kov, tab sis nws yog thawj zaug ua kom nws ua haujlwm ntawm cov xov tooj ntawm tes.

Tseeb tiag, Steve Jobs yuav luag plam tawm capacitive touch technology ntawm iPhone thiab iPad tag nrho. Qhov ntawd yog vim nws tsis pom "ib qho txiaj ntsig rau lub tswv yim" ntawm kev kov ntau:qhov kev ua tiav hauv kov npo zaub thev naus laus zis uas ua rau iOS li niaj zaus xws li "pinch-to-zoom" ua tau.

Thiab nws tau raug tso tseg rau Ive thiab ob peb lwm tus tub ntxhais Apple cov neeg ua haujlwm kom txuag nws. Multi-kov ntawm Apple pib nrog kev ua yeeb yam los ntawm Greg Christie thiab Bas Ording, uas tau siv ob peb lub hlis hauv xyoo 2004 tsim cov qauv ua haujlwm ntawm lub vijtsam zoo li iPad, qhov loj ntawm lub rooj sib tham. Ntawm nws, ib tus neeg tuaj yeem siv ob txhais tes txav cov folders nyob ib puag ncig, qhib cov cim, ntsws thiab nthuav cov ntaub ntawv, thiab "scroll" vertically thiab horizontally siv swipes. Lawv tau nthuav tawm cov thev naus laus zis rau cov thawj coj ntawm Apple los ntawm kev tso nws mus rau qhov screen video. Cov hauj lwm tau zoo siab txog kev tsim cov ntsiav tshuaj, tab sis nws tsis tshua nyiam los ntawm qhov demo.

Tom qab xav txog lub tswv yim rau ob peb hnub, txawm li cas los xij, Txoj Haujlwm tuaj ncig - thiab khiav nws dhau los ntawm Apple cov thawj coj uas nws cov kev xav nws ntseeg. Cov hauj lwm tsis tau ntseeg tam sim ntawd nws tuaj yeem ua rau lub ntsiav tshuaj ua cov khoom lag luam loj, tab sis raws li lub xov tooj nws tuaj yeem pom daim ntawv thov. Nws hais rau Tony Fadell kom "mus xyuas seb yuav ua li cas ntxiv qhov kev sib tham sib kov no rau lub vijtsam ntawm lub xov tooj. Lub xov tooj txias tiag tiag, me me, nyias nyias."

Tus so, raws li lawv hais, yog keeb kwm.

Leej twg invented touch screen?

Xyoo 1965,EA Johnson ntawm Royal Radar Tsim nyob rau hauv Malvern, UK tau suav tias yog thawj tus neeg tsim khoom uas tau tsim lub capacitive touch screen.. Nws luam tawm nws tsab xov xwm hais txog lub tshuab kov npo hauv Ergonomics hauv xyoo 1967.

Xyoo 1971, Dr. Samuel Hurst (tus tsim ntawm Elographics) tau tsim cov khoom siv kov uas tau patented los ntawm University of Kentucky Research Foundation. Tab sis qhov kov sensor tsis yog pob tshab.

Xyoo 1971, Plato IV lub davhlau ya nyob twg hauv University of Illinois yog thawj lub khoos phis tawj dav dav nrog cov tshuab hluav taws xob infrared.

Xyoo 1974, thawj pob tshab kov npo nrog ITO (indium tin oxide) ua tus neeg xyuas pib tsim los ntawm Sam Hurst thiab Elographics.

Xyoo 1977, Elographics tau tsim cov thev naus laus zis thev naus laus zis (RTP) uas tseem siv niaj hnub no. Lub Ob Hlis 24, 1994, lub tuam txhab tau hloov nws lub npe los ntawm Elographics mus rau Elo Touch Systems.

Nyob rau hauv 1982, Thawj multi-touchscreen ntaus ntawv tau tsim nyob rau hauv University of Toronto.

Xyoo 1983, Myron Krueger tau tshaj tawm Video Place, uas tuaj yeem taug qab ob txhais tes, ntiv tes thiab cov neeg uas lawv koom nrog.

Xyoo 1983, HP (Hewlett Packard) tau tshaj tawm HP -150 nrog kov npo thev naus laus zis. Infrared kov vaj huam sib luag tau siv.

Xyoo 1984, Bob Boie ntawm Tswb Labs tsim thawj multitouch screen overlay.

Xyoo 1993, Apple tso tawm Newton PDA nruab nrog kev sau ntawv; thiab IBM tso tawm thawj lub xov tooj hu ua Simon nrog lub vijtsam kov uas tuaj yeem siv los hu xov tooj.

Xyoo 1996, Xibtes tau qhia Pilot series PDA nrog cov cuab yeej siv tshuaj ntsuam xyuas qib siab.

Xyoo 1999, Wayne Westerman thiab John Elias ntawm FingerWorks tau nthuav qhia ntau yam kev taw qhia touchscreen.

Xyoo 2002, Microsoft tau tshaj tawm Windows XP ntsiav tshuaj nrog kov thev naus laus zis.

Nyob rau hauv 2007, thov tso tawm iPhone thiab pib lub era ntawm kov screen technology.

Xyoo 2011, Microsoft thiab Samsung koom tes los qhia txog SUR40 kov muaj peev xwm nto nrog PixelSense thev naus laus zis.

Thaum twg touchscreen computers tawm?

Hauv keeb kwm ntawm lub vijtsam kov nws pib ua lag luam xyoo 1983 thaum HP (tom qab ntawd hu ua Hewlett-Packard) tsim HP -150. Lub khoos phis tawj no tau nthuav tawm 9 "CRT zaub, nrog cov ntsuas hluav taws xob (IR) nyob ib puag ncig ntawm ntug uas tuaj yeem ntes thaum tus neeg siv tus ntiv tes cuam tshuam nrog lub vijtsam.

Puas yog capacitive touch screens hnav?

Peb yuav tsum faib cov "hnav" lub cev los yog hluav taws xob. Lub cev, nws nyuaj rau hnav koj lub vijtsam kov tshwj tsis yog tias koj siv cov yuam sij lossis pob zeb diamond txhawm rau kos lub touchscreen. Qhov hardness ntawm qhov sib txawv touchscreens txawv. Qee qhov qis kawg kov tuaj yeem ua "mos" li 2H, tab sis iPhone nto tuaj yeem nyuaj li 9H ua los ntawm chemically tempered iav vaj huam sib luag.

Dab tsi ua rau capacitive touch screen zaub technology?

Capacitive touchscreens, lossis capacitive touch panels (CTP) yog tsim los ntawm ntau txheej iav los yog insulator. Sab hauv cov khoom siv hluav taws xob ua hluav taws xob thiab yog li txheej txheej sab nrauv los ua lub capacitor. Thaum koj tus ntiv tes kaw lossis kov lub vijtsam, koj lub cev / ntiv tes hloov pauv hluav taws xob los ntawm qee qhov sib txawv. Lub touch sensing circuitry yuav hnov ​​​​qhov kev hloov pauv thiab ua rau qhov kov.

Evolution ntawm capacitive touch screen keeb kwm

Kuj ceeb tias, thawj lub vijtsam kov hauv keeb kwm yog cov khoom siv hluav taws xob ntau dua li cov thev naus laus zis hauv xyoo 1960s.. Thaum lub sij hawm ntawd, lub touchscreen yog loj, qeeb, imprecise thiab kim heev. Lub tshuab yog mono-touch lossis ib qho kov thiab yooj yim. Lub capacitive touchscreen technologies tsis muaj kev vam meej ntau vim yog kev vam meej loj ntawm lubresistive kov vaj huam sib luag. Tab sis tib neeg nyiam tshawb nrhiav cov tswv yim tshiab. Qhov kev hloov pauv tuaj rau xyoo 2007 nrog kev qhia txog iPhone, lub iPhone qhia txog qhov tseeb, pheej yig, ntau lub tshuab kov.

Capacitive touchscreen tam sim no thiab yav tom ntej

Tam sim no, nws yuav luag tsis xav txog yog tias peb tsis muaj lub peev xwm kov lub vijtsam zaub thev naus laus zis. Nws tau dhau los ua ib feem ntawm peb lub neej niaj hnub, coj mus rhaub, luag, flick, zoom hauv / tawm, los so thiab lwm yam.Lub touchscreen zaub technology tsis tsuas yog siv hauv ntsiav tshuaj lossis smartphone. Touchscreens yeej muaj nyob txhua qhov chaw. Tsev, tsheb, tsev noj mov, khw muag khoom, dav hlau, txhab nyiaj hauv ATMs, point-of-muag, kiosks, huab cua tswj thiab lwm yam, nyob qhov twg-lawv sau peb lub neej nyob rau hauv qhov chaw pej xeem thiab ntiag tug. Lub touchscreen hloov los ntawm mono-kov mus rau ntau qhov kov nrog ntau li 16 lub ntsiab lus kov, mus rau 3D kov (yuav tsum kov los ntawm nias down), hover kov (tsis muaj tiag tiag kov), kom haptic kov (xav qhov kev co tom qab kov tau zoo) , rau hnab looj tes kov cov ntaub ntawv (los ntawm latex mus rau nylon rau ntaub plaub nrog txawv thickness), rau ntub kov (nrog dej los yog dej ntsev), nrog rau cov ntaub ntawv sib txawv (los ntawm tus ntiv tes, xaum, stylus thiab lwm yam), rau cov khoom sib txawv ntawm cov khoom nto. (iav, yas, sapphire siv lead ua), mus rau qhov sib txawv (pav, nkhaus, kheej kheej), mus rau txawv thickness ( tuab, nyias, tsis muaj tseeb sensor iav (ntawm-cell), tsis muaj tiag kov vaj huam sib luag (hauv-cell))... capacitive touchscreen technology tuaj yeem laus tab sis peb tuaj yeem pom nws tseem hluas. Raws li lub ntsiab HMI (tib neeg tshuab interface input / output device), tseem muaj ntau yam tuaj.
