Isikrini sokuthinta esilinganiselwe

Ukuchazwa Komkhiqizo

Iphaneli yesikrini esingu-21,5 esilinganiselwe esine-ILitek Touch Controller IC ingasekela ukusebenza ngamagilavu aminyene, ingilazi emnyama enolaka kanye ne-PC ebanzi phezulu, ikakhulukazi esetshenziswa emishini yezimboni, ezokwelashwa. Ukwenza ngokwezifiso okujulile kufaka phakathi ukwelashwa okukhona, okungaphezulu komhlaba afana ne-AG AS neminye imiphumela ekhethekile kusekelwa; Zonke izinhlobo uma amabhodi wokuguqula ama-interface kanye namabhodi wokushayela ahlinzekwa ukuze ahlangabezane nezidingo ezivela kumakhasimende ahlukahlukene.

Q & a

Q: Yiziphi iziphakamiso ekusebenzeni kwe-anti-esd yesikrini se-capacide Touch ukufanisa amakhasimende aphela imikhiqizo?

A: Ngakolunye uhlangothi, uthuthukise amandla okulwa ne-esd we-IC, ngakolunye uhlangothi, ukufeza ukuvikela okuhle kwe-TP ngokumelene ne-ESD. Izivikelo eziningi ze-ESD akufanele zibe yinkinga. Uma isikhala sinqunyelwe impela, indinganiso ingancishiswa ngokufanele, futhi amandla okulwa ne-esd anqunywa ngokwesakhiwo somshini wonke. Kunconywe ukuthi i-FPC yenyuse ukumelana nentambo ye-2K noma engeza umjikelezo ofanele wesikhumba kanye ne-TVS tube. Ngokuphathelene nenkinga kagesi ophelele, kufanele siqale siqonde iqiniso lokuthi uhlelo lwe-ESD luhlukile kwi-IC ESD. I-System ESD iqinisekiswe ikakhulukazi ngokwakheka kwesistimu. Ukuthuthukiswa kwe-IC ESD kuyisici esisodwa sohlelo lwe-ESD sexD. Ngakho-ke, noma ngabe i-ESD ye-IC ithuthukiswa, ukwakheka komzimba wesikrini kusadinga ukwelashwa kwe-ESD ukuqinisekisa izidingo zohlelo lwe-ESD. Okwesistimu ESD, into ebaluleke kakhulu ukwakheka komshini. Uma inqubo yenzelwe kahle futhi amandla ahambisana nomzimba wesikrini mancane, ukwakheka kwe-ESD kwesikrini kungavuselelwa.

Q: Ayini amasu we-ESD ekuhlolweni kwe-EMC yemikhiqizo ephelele yokugcina?

A: Isixazululo esiphelele ukugeleza ugesi ophelele emhlabathini. Kuneziphakamiso ezilandelayo: 1), ukuhlinzekwa kwamandla kanye ne-TV TV TV TV TV: Ukuvikelwa kwamandla okunikezela kwamandla i-VCC, i-TVS tube ingaxhunyaniswa futhi ixazululwe. I-TV TV TUBE ifana kakhulu ne-voltage Regulator Diode. Ine-voltage ekalwe. Umehluko ukuthi isivinini sayo sokuphendula sishesha kakhulu futhi sinomphumela omuhle wegesi ngogesi we-static.2) Ukuvikelwa kwe-ESD yangaphandle kwe-Interface Signal Line: Ungabheka futhi uxhume i-Refper Diode ukukhombisa ukunikezwa kwamandla abucayi: Ezinye izihlungi ze-IC zitholakala kakhulu kugesi ovuselelayo. Lapho ukuhlolwa kwe-ESD kwenziwa, setha kabusha kabusha noma ukufa kwenzeka njalo. Isizathu ukuthi i-PIN ye-Power Supply ivame ukuphazamiseka. Kulokhu, ukuhlunga kwe-LC kungangezwa ku-Power Vaires.4) Izidingo zePCB ezihamba ngezinyawo: I-PCB kufanele ivezwe ngangokunokwenzeka. Uma kuyiphaneli ephindwe kabili, zombili izinhlangothi kufanele zifakwe ngethusi endaweni enkulu, futhi kufanele kube nezimbobo ezanele zomhlaba. Uma kuyibhodi elinobungqingili noma ngaphezulu, ungqimba oluseduze lwendiza yengxenye enkulu kufanele isethwe kwizidingo ze-.5) eziphansi: Ukukhipha ngempumelelo ugesi we-tuli, ukukhulula ugesi kahle, isisekelo esihle kufanele siqinisekiswe. Isibonelo, ama-elekthronikhi wezokwelapha, imikhiqizo ejwayelekile yezokwelapha yezokwelapha enjengeziqapheli, kuzoba nesisekelo esilinganayo sokuphela ngemuva kwe-fuselage. Lapho wenza izivivinyo ze-ESD, lesi sisekelo sesisekelo sixhumeke emhlabeni, ngakho-ke kunendlela yokukhipha i-static Electricity.6) I-PCB Layout Wiring: Uma i-capacitor ye-PCB yasheshi Uma umugqa wezimpawu ezibucayi yinde kakhulu, kuzokwethulwa imali engalindelekile ye-electromagnetic. Ngokwe-anti-esd, amadivaysi abucayi noma imigqa yesiginali (efana nokusetha kabusha) kufanele igcinwe kude namaphethelo we-PCB ukuvikela ukuphuma komoya ekuphazanyisweni ngqo namadivayisi nemigqa yesiginali. Unqenqemeni lwe-PCB kufanele lube nobubanzi obuthile begebe noma ithusi.
