Isikrini sokuchukumisa iintambo ezine
Isikrini se-touch screen sine-resort ezimbini.Omnye umaleko unebhasi ethe nkqo kumaphethelo asekhohlo nasekunene kwesikrini, kwaye omnye umaleko unebhasi ethe tye ezantsi nangaphezulu kwesikrini, njengoko kubonisiwe kuMfanekiso 1.
Umzobo 1 Isahluli sombane siphunyezwa ngokudibanisa izichasi ezimbini kuthotho [6]
Ukulinganisa kwicala le-X-axis, calanye ibhasi ekhohlo ukuya ku-0V, kunye nebhasi ekunene eya kwi-VREF.Xhuma ibhasi ephezulu okanye esezantsi kwi-ADC, kwaye umlinganiselo unokwenziwa xa iileya eziphezulu kunye nezantsi zidibene.
Umzobo 2 Iileya ezimbini ezixhathisayo zesikrini esinentambo ezine
Ukwenzela ukulinganisa kwicala le-Y-axis, ibhasi ephezulu ityekele kwi-VREF kwaye ibhasi esezantsi ityekele kwi-0V.Xhuma i-terminal yokufaka i-ADC kwibhasi ekhohlo okanye ibhasi elungileyo, kwaye i-voltage inokulinganiswa xa umgca ophezulu udibanisa nomgangatho ongezantsi.Umzobo we-2 ubonisa imodeli elula yesikrini socingo olune-wire xa iileya ezimbini zidibene.Kwisikrini esinentambo ezine, indlela efanelekileyo yokudibanisa kukudibanisa ibhasi ethambekele kwi-VREF kwi-terminal ye-reference ye-reference ye-ADC, kunye nokudibanisa i-bus set kwi-0V kwi-terminal ye-reference ye-reference ye-ADC.

Izaleko ezimbini ezixhathisayo zesikrini socingo esichukumisayo ezine
Isikrini sokuchukumisa iintambo ezintlanu
Isikrini esine-five-wire touch screen sisebenzisa i-resissive layer kunye ne-conductive layer.Uluhlu lwe-conductive lunoqhagamshelwano, ngokuqhelekileyo kumda walo kwelinye icala.Kukho unxibelelwano kwikona nganye kwezine zomaleko ochasayo.Ukuze ulinganise kwicala le-X-axis, susa iikona eziphezulu zasekhohlo kunye nezisezantsi ekhohlo ukuya kwi-VREF, kwaye iikona eziphezulu zasekunene nezisezantsi zisekelwe.Ekubeni iikona ezisekhohlo nasekunene zine-voltage efanayo, umphumo ufana nebhasi edibanisa emacaleni asekhohlo nasekunene, afana nendlela esetyenziswe kwi-screen touch touch screen.Ukuze kulinganiswe ecaleni kwe-axis ye-Y, ikona ephezulu ekhohlo kunye nekona ephezulu ngasekunene i-offset ukuya kwi-VREF, kwaye ikona esezantsi ekhohlo kunye nekona esezantsi ekunene i-offset kwi-0V.Ekubeni iikona eziphezulu kunye nezantsi zikwi-voltage efanayo, umphumo uphantse ufana nebhasi edibanisa imida ephezulu nangaphantsi, efana nendlela esetyenziswe kwisikrini socingo olune.Inzuzo yale algorithm yokulinganisa kukuba igcina i-voltage kwikona ephezulu ngasekhohlo nasezantsi ingatshintshi;kodwa ukuba ulungelelwaniso lwegridi luyasetyenziswa, i-X kunye ne-Y axes kufuneka ibuyiselwe umva.Kwisikrini sokuchukumisa iintambo ezintlanu, eyona ndlela yoqhagamshelo kukudibanisa ikona ephezulu ekhohlo (icalanye njenge VREF) kwiterminal yegalelo elilungileyo lereferensi yeADC, kwaye uqhagamshele ikona esezantsi ekhohlo (icalanye ukuya ku-0V) kwigalelo elibi lereferensi. itheminali yeADC.
I-Glas substrate yimathiriyeli ekrwada ebalulekileyo yokuveliswa kwe-TFT-LCD, kwaye i-akhawunti yeendleko zayo malunga ne-15% ukuya kwi-18% yexabiso lilonke le-TFT-LCD.Iphuhliswe ukusuka kumgca wesizukulwana sokuqala (300mm × 400mm) ukuya kumgca wesizukulwana seshumi sangoku (2,850mm × 3,050).mm), ihambe ixesha elifutshane leminyaka engamashumi amabini.Nangona kunjalo, ngenxa yeemfuno eziphezulu kakhulu zokwakheka kweekhemikhali, ukusebenza kunye neemeko zenkqubo yemveliso ye-TFT-LCD substrates zeglasi, itekhnoloji yemveliso yeglasi ye-TFT-LCD yeglasi yehlabathi kunye nentengiso kudala isetyenziswa yiCorning eUnited States, iAsahi Glass kunye. Electric Glass, etc. Monopolized ziinkampani ezimbalwa.Ngaphantsi kokukhuthazwa okunamandla kophuhliso lweemarike, ilizwe lelizwe lam laqala ukuthatha inxaxheba ngokusebenzayo kwi-R & D kunye nokuveliswa kwe-TFT-LCD substrates zeglasi ngo-2007. Okwangoku, inani le-TFT-LCD imigca yokuvelisa i-glass substrate yesizukulwana sesihlanu kwaye ngasentla zakhiwe China.Kucwangciswe ukusungula iiprojekthi ezimbini ze-8.5 zesizukulwana esiphezulu semveliso yolwelo lweglasi yeglasi kwisiqingatha sesibini sowama-2011. Oku kubonelela ngesiqinisekiso esibalulekileyo sokwenziwa kwasekhaya kwemathiriyeli ekrwada enyukayo kubavelisi be-TFT-LCD kwilizwe lam kunye nokubaluleka okubalulekileyo. ukuncitshiswa kweendleko zokuvelisa.
Seven-wire touch screen
Indlela yokuphunyezwa kwesikrini se-7-wire touch screen iyafana ne-five-wire touch screen ngaphandle kokuba umgca omnye wongezwa kwikona eliphezulu lasekhohlo kunye nekona elisezantsi lasekunene.Xa usenza umlinganiselo weskrini, qhagamshela ucingo olunye kwikona ephezulu ekhohlo kwi-VREF, kunye nolunye ucingo kwi-positive reference terminal ye-SAR ADC.Ngelo xesha, enye intambo ekhoneni elisezantsi lasekunene ixhunywe kwi-0V, kwaye enye intambo ixhunyiwe kwi-terminal ye-reference ye-negative ye-SAR ADC.I-conductive layer isasetyenziselwa ukulinganisa i-voltage ye-voltage divider.
Isikrini sokuchukumisa iintambo ezisibhozo
Ngaphandle kokongeza ucingo kwibhasi nganye, indlela yokuphunyezwa kwesikrini socingo olusibhozo lufana nelo locingo olune-screen touch.Kwibhasi ye-VREF, olunye ucingo lusetyenziselwa ukuqhagamshela kwi-VREF, kwaye olunye ucingo lusetyenziswa njengegalelo elichanekileyo lereferensi ye-SAR ADC's digital-to-analog converter.Kwibhasi ye-0V, olunye ucingo lusetyenziselwa ukuqhagamshela kwi-0V, kwaye olunye ucingo lusetyenziswa njenge-negative reference input ye-SAR ADC's digital-to-analog converter.Nayiphi na iingcingo ezine kumaleko angakhethi cala angasetyenziselwa ukulinganisa umbane wesahluli sombane.
