ukufaka kwisixhobo esinye. Ekubeni amaqhosha ephaneli yokuchukumisa ayisoftware, hayi ihardware,

ii-interfaces zitshintshwa lula ngesoftware.

Ukusetyenziswa okuphambili kweemonitha ze-LCD ezineephaneli zokuchukumisa. Ezi zixhobo zisetyenziswa kwiindawo ezininzi ezibanzi.

Nangona iphaneli yokuchukumisa ifuna uluhlu olubanzi lweempawu, kuquka ukubonakala kwesibonisi ngaphezu kwako konke, kunye nokuchaneka kokuva indawo, impendulo ekhawulezileyo kwingeniso, ukuqina, kunye neendleko zokufakela, iimpawu zazo zahluka kakhulu ngokuxhomekeke kwiindlela ezisetyenziswayo ukuva igalelo lokuchukumisa. Ezinye iindlela eziqhelekileyo zokuva iphaneli yokuchukumisa zixutyushwa ngezantsi.

Iiphaneli zokuchukumisa ifilimu ethintelayo

Ukusukela ngo-2010, ifilimu ekhuselayo yayiyeyona ndlela isetyenziswa kakhulu yokuva kwimarike yephaneli yokuchukumisa. Iiphaneli zokuchukumisa ezisekelwe kule ndlela zibizwa ngokuba ziiphaneli zokuchukumisa ifilimu ezithintela uxinzelelo okanye ezithintela i-analog. Ukongeza kwiimonitha ze-LCD ezizimeleyo, le teknoloji isetyenziswa kuluhlu olubanzi lwezixhobo ezincinci ukuya kweziphakathi, kubandakanya ii-smartphones, iifowuni eziphathwayo, ii-PDA, iinkqubo zokuhambisa iimoto, kunye neNintendo DS.

Ngale ndlela, indawo ekwisikrini edibene nomnwe, istylus, okanye enye into ifunyanwa ngokusebenzisa utshintsho kuxinzelelo. Isikrini sinesakhiwo sangaphakathi esilula: isikrini seglasi kunye nesikrini sefilimu esahlulwe ngumngxuma omxinwa, ngasinye sinefilimu ye-electrode ebonakalayo (umaleko we-electrode) eqhotyoshelweyo. Ukucinezela umphezulu wesikrini kucinezela ii-electrode kwifilimu kunye neglasi ukuba ziqhagamshelane, nto leyo ebangela ukuhamba komsinga wombane. Indawo yokunxibelelana ichongwa ngokubona olu tshintsho kwi-voltage.

Iingenelo zale nkqubo ziquka ukwenziwa kwayo okungabizi kakhulu, ngenxa yesakhiwo sayo esilula. Le nkqubo ikwasebenzisa umbane omncinci kunezinye iindlela, kwaye ulwakhiwo oluvelayo luyakwazi ukumelana nothuli namanzi kuba umphezulu ugqunywe yifilimu. Ekubeni igalelo libandakanya uxinzelelo olusetyenziswa kwifilimu, ingasetyenziselwa igalelo kungekuphela nje ngeminwe engenanto, kodwa nokuba unxibe iiglavu okanye usebenzisa i-stylus. Ezi zikrini zingasetyenziselwa ukufaka umbhalo obhalwe ngesandla.

Iingxaki ziquka ukuhanjiswa kokukhanya okuphantsi (umgangatho wokubonisa ophantsi) ngenxa yefilimu kunye neeleya ezimbini ze-electrode; ukuqina okuphantsi kunye nokumelana nokutshayiswa; kunye nokuchaneka okunciphileyo kokufunyanwa ngeesayizi zesikrini esikhulu. (Ukuchaneka kunokugcinwa ngezinye iindlela—umzekelo, ukwahlula isikrini kwiindawo ezininzi zokufunyanwa.)

Iiphaneli zokuchukumisa ezikwaziyo ukuthwala amandla

Iiphaneli zokuchukumisa ezikwaziyo ukuchukumisa zimele indlela yesibini yokuva esetyenziswa kakhulu emva kweephaneli zokuchukumisa ifilimu ezikwaziyo ukuchukumisa. Ngokuhambelana namagama asetyenzisiweyo kwiiphaneli zokuchukumisa ezikwaziyo ukuchukumisa ezichazwe apha ngasentla, ezi zikwabizwa ngokuba ziiphaneli zokuchukumisa ze-analog capacitive. Ngaphandle kweemonitha ze-LCD ezizimeleyo, ezi zihlala zisetyenziswa kwizixhobo ezifanayo neephaneli zokuchukumisa ifilimu ezikwaziyo ukuchukumisa, ezifana neefowuni eziphathwayo kunye neefowuni eziphathwayo.

Ngale ndlela, indawo apho ukuchukumisa kwenzeka khona ichongwa kusetyenziswa ii-sensors ukuze zive utshintsho oluncinci kumbane obangelwa kukudibana nomnwe okanye utshintsho kumthamo we-electrostatic (umthwalo). Ekubeni ii-sensors zisabela kumthamo wombane ozinzileyo womzimba womntu xa umnwe usondela kwisikrini, zingasetyenziswa ngendlela efana nokuhambisa isalathisi kwindawo echukunyiswe kwisikrini.

Iindidi ezimbini zeephaneli zokuchukumisa zisebenzisa le ndlela: iiphaneli zokuchukumisa ezinomthamo ophezulu kunye neephaneli zokuchukumisa ezinomthamo obonakalayo. Izakhiwo zangaphakathi zahlukile phakathi kwezi ntlobo zimbini.

Iiphaneli zokuchukumisa ezinomthamo ophezulu

Iipaneli zokuchukumisa ezinomphezulu zidla ngokusetyenziswa kwiipaneli ezinkulu. Ngaphakathi kwezi paneli, ifilimu ye-electrode ebonakalayo (umaleko we-electrode) ibekwa phezu kwe-substrate yeglasi, igqunywe yisigqubuthelo esikhuselayo. I-voltage yombane ifakwa kwii-electrodes ezibekwe kwiikona ezine ze-substrate yeglasi, ivelisa intsimi yombane ene-voltage ephantsi efanayo kuyo yonke ipaneli. Ii-coordinates zendawo apho umnwe uchukumisa isikrini zichongwa ngokulinganisa utshintsho oluvelayo kumthamo we-electrostatic kwiikona ezine zepaneli.

Nangona olu hlobo lwephaneli yokuchukumisa ene-capacitive lunesakhiwo esilula kunephaneli yokuchukumisa ene-capacitive eqikelelweyo kwaye ngenxa yesi sizathu inika ixabiso eliphantsi, kunzima ngokwesakhiwo ukubona unxibelelwano kwiindawo ezimbini okanye ngaphezulu ngaxeshanye (ukuchukumisa okuninzi).

Iiphaneli zokuchukumisa ezicwangcisiweyo

Iiphaneli zokuchukumisa ezicwangcisiweyo zihlala zisetyenziselwa ubungakanani obuncinci besikrini kuneephaneli zokuchukumisa ezicwangcisiweyo eziphezulu. Ziye zatsala ingqalelo enkulu kwizixhobo eziphathwayo. I-iPhone, i-iPod Touch, kunye ne-iPad zisebenzisa le ndlela ukufezekisa ukusebenza okuchanekileyo kokuchukumisa okuninzi kunye nesantya esiphezulu sokuphendula.

Ulwakhiwo lwangaphakathi lwala maphaneli okuchukumisa luqulathe isiseko esiquka itshiphu ye-IC yokucubungula izibalo, apho kukho umaleko wee-electrode ezininzi ezicacileyo ezibekwe kwiipateni ezithile. Umphezulu ugqunywe ngeglasi ekhuselayo okanye isigqubuthelo seplastiki. Xa umnwe usondela kumphezulu, amandla e-electrostatic phakathi kwee-electrode ezininzi ayatshintsha ngaxeshanye, kwaye indawo apho unxibelelwano lwenzeka khona inokuchongwa ngokuchanekileyo ngokulinganisa umlinganiselo phakathi kwale mijelo yombane.

Uphawu olukhethekileyo lwephaneli yokuchukumisa eqikelelweyo kukuba inani elikhulu lee-electrode lenza ukuba kubonwe ngokuchanekileyo uqhagamshelwano kwiindawo ezininzi (ukuchukumisa okuninzi). Nangona kunjalo, iiphaneli zokuchukumisa eziqikelelweyo ezine-indium-tin-oxide (ITO) ezifumaneka kwiifowuni eziphathwayo nakwizixhobo ezifanayo azifanelekanga ukusetyenziswa kwizikrini ezinkulu, kuba ubungakanani besikrini obukhulayo bubangela ukuxhathisa okwandileyo (oko kukuthi, ukuhanjiswa kancinci kombane), okwandisa ubungakanani bempazamo kunye nengxolo ekufumaneni iindawo ezichukunyisiweyo.

Iipaneli ezinkulu zokuchukumisa zisebenzisa iipaneli zokuchukumisa ezicwangcisiweyo zocingo oluphakathi apho iingcingo zombane ezincinci kakhulu zibekwe kwigridi njengomaleko we-electrode ocacileyo. Nangona ukumelana okuphantsi kwenza iipaneli zokuchukumisa ezicwangcisiweyo zocingo oluphakathi zibe novakalelo olukhulu, azifanelekanga kakhulu kwimveliso yobuninzi kune-ITO etching.

Ngaphezulu, sishwankathele umahluko phakathi kweentlobo ezimbini zeepaneli zokuchukumisa ezikwaziyo ukuchukumisa. Iimpawu zizonke zeepaneli ezinjalo ziquka into yokuba ngokungafaniyo neepaneli zokuchukumisa ifilimu ezikwaziyo ukuchukumisa, aziphenduli xa zichukunyiswa yimpahla okanye isitayile esiqhelekileyo. Zinokumelana okukhulu nothuli kunye namaconsi amanzi kwaye zihlala ixesha elide kwaye ziyaxhathisa ukukrwela. Ukongeza, ukuhanjiswa kwazo kokukhanya kuphezulu, xa kuthelekiswa neepaneli zokuchukumisa ifilimu ezikwaziyo ukuchukumisa.

Kwelinye icala, ezi paneli zokuchukumisa zifuna umnwe okanye i-stylus ekhethekileyo. Azinakusetyenziswa xa zinxibe iiglavu, kwaye zichaphazeleka lula zizakhiwo zesinyithi ezikufutshane.

Iiphaneli zokuchukumisa ze-surface acoustic wave (SAW)

Iiphaneli zokuchukumisa ze-Surface acoustic wave (SAW) zaphuhliswa ikakhulu ukuze kujongwane neengxaki zokuhanjiswa kokukhanya okuphantsi kwiiphaneli zokuchukumisa zefilimu ezikhuselayo—oko kukuthi, ukufezekisa iiphaneli zokuchukumisa ezikhanyayo ezinamazinga aphezulu okubonakala. Ezi zikwabizwa ngokuba ziiphaneli zokuchukumisa ze-surface wave okanye ze-acoustic wave. Ngaphandle kweemonitha ze-LCD ezizimeleyo, ezi zisetyenziswa kakhulu kwiindawo zikawonke-wonke, kwizixhobo ezifana nee-terminals ze-point-of-sale, ii-ATM, kunye nee-kiosk ze-elektroniki.

Ezi paneli zibona indawo yesikrini apho unxibelelwano lwenzeka khona ngomnwe okanye ngenye into kusetyenziswa ukuncitshiswa kwamaza e-ultrasound elastic kumphezulu. Ulwakhiwo lwangaphakathi lwala maphaneli lwenzelwe ukuba ii-transducers ezininzi ze-piezoelectric ezicwangciswe kwiikona ze-substrate yeglasi zidlulise amaza e-ultrasound elastic kumphezulu njengeentshukumo kumphezulu wephaneli, ezifunyanwa zii-transducers ezifakwe ecaleni kwezo zithumelayo. Xa isikrini sichukunyiswa, amaza e-ultrasound ayafunxwa kwaye ancitshiswe ngumnwe okanye enye into. Indawo ichongwa ngokubona olu tshintsho. Ngokwemvelo, umsebenzisi akaziva ezi ntshukumo xa echukumisa isikrini. Ezi paneli zibonelela ngokulula kokusetyenziswa.

Amandla olu hlobo lwephaneli yokuchukumisa aquka ukuhanjiswa kokukhanya okuphezulu kunye nokubonakala okuphezulu, kuba isakhiwo asifuni ifilimu okanye ii-electrode ezicacileyo kwisikrini. Ukongeza, iglasi yomphezulu inika ukuqina okungcono kunye nokumelana nokukrwela kunephaneli yokuchukumisa ekwaziyo ukuthwala. Enye inzuzo kukuba nokuba umphezulu uyakrwela ngandlela ithile, iphaneli ihlala ivakalelwa kukuchukunyiswa. (Kwiphaneli yokuchukumisa ekwaziyo ukuthwala, ukukrwela komphezulu ngamanye amaxesha kunokuphazamisa imiqondiso.) Ngokwesakhiwo, olu hlobo lwephaneli luqinisekisa uzinzo oluphezulu kunye nobomi benkonzo ende, ngaphandle kotshintsho ngokuhamba kwexesha okanye ukuphambuka kwindawo.

Amanqaku abuthathaka aquka ukuhambelana neminwe kunye nezinto ezithambileyo kuphela (ezifana neeglavu) ezifunxa amaza e-ultrasound surface elastic. Ezi paneli zifuna ii-styluses ezikhethekileyo kwaye zinokusabela kwizinto ezifana namaconsi amanzi okanye izinambuzane ezincinci kwipaneli.

Nangona kunjalo, ezi paneli zokuchukumisa azinazo iingxaki ezininzi. Uphuhliso lwakutshanje olufana nokuphuculwa kwetekhnoloji yokuvelisa lukwaphucula ukusebenza kwazo ngeendleko.

Iiphaneli zokuchukumisa ezibonakalayo (iiphaneli zokuchukumisa zemifanekiso ye-infrared optical)

Udidi lweephaneli zokuchukumisa ezibonakalayo luquka iindlela ezininzi zokuva. Inani leemveliso ezisebenzisa iiphaneli zokuchukumisa ze-infrared optical imaging ezisekelwe kwiisensa zemifanekiso ye-infrared ukuze ziva indawo ngokusebenzisa unxantathu likhule kwiminyaka yakutshanje, ikakhulu phakathi kweephaneli ezinkulu.

Iphaneli yokuchukumisa kolu didi ine-infrared LED enye nganye kwiziphelo zasekhohlo nasekunene zephaneli, kunye nesenzi somfanekiso (ikhamera). Iteyiphu yokubonakalisa ukukhanya kwesiganeko ecaleni kwe-axis yesiganeko incamathiselwa kumacala asekhohlo, asekunene, nasezantsi aseleyo. Xa umnwe okanye enye into ichukumisa isikrini, isenzi somfanekiso sibamba izithunzi ezenziwe xa ukukhanya kwe-infrared kuvaliwe. Ii-coordinates zendawo yokunxibelelana zifunyanwa yi-triangulation.

Iiphaneli zokuchukumisa ze-induction ye-electromagnetic

Nangona olu hlobo lwahlukile kancinci kwiiphaneli zokuchukumisa ezingentla, makhe siqwalasele umxholo weephaneli zokuchukumisa ze-electromagnetic induction. Le ndlela isetyenziswa kwizixhobo ezinje ngeethebhulethi zemizobo ye-LCD, iiPC zeethebhulethi, kunye neebhuthi zesitikha seefoto ze-purikura.

Le ndlela yokufaka iitablethi zemizobo, ezazingenazo iimonitha ekuqaleni, ifikelela kwiipaneli zokuchukumisa ezichanekileyo ngokudibanisa isenzi kunye nephaneli yeLCD. Xa umsebenzisi echukumisa isikrini ngestylus ekhethekileyo evelisa intsimi yemagnethi, iisenzi ezikwiphaneli zifumana amandla e-electromagnetic kwaye ziyisebenzisele ukuva indawo yepeni.

Ekubeni kusetyenziswa i-stylus ekhethekileyo xa kufakwa, ukufaka usebenzisa umnwe okanye i-stylus eqhelekileyo akunakwenzeka, kwaye le ndlela inezicelo ezimbalwa. Sekunjalo, oku kuneendawo ezilungileyo nezimbi. Isusa iimpazamo zokufaka ngenxa yendawo engqongileyo okanye ukuphathwa kwesikrini okungacwangciswanga. Ekubeni le teknoloji yayijoliswe ekusetyenzisweni kwiithebhulethi zemizobo, inika ukuchaneka okuphezulu kwe-sensor—okwenza kube nokwenzeka, umzekelo, ukutshintsha ububanzi bomgca kakuhle ngokubona ngokuchanekileyo uxinzelelo olucinezelwa ngalo i-stylus kwisikrini (umthamo we-electrostatic). Le ndlela yoyilo ikwanika isikrini ukuhanjiswa kokukhanya okuphezulu kunye nokuqina.
