Imodeli ye-LCD

Izici zobuchwepheshe

I-LCM ingumkhiqizo we-LCD ohlanganisiwe ophezulu uma uqhathaniswa nengilazi.Ngosayizi omncaneIsibonisi se-LCD, i-LCM ingaba lula kakhulu ukuxhuma kuma-microcontrollers ahlukahlukene (njengemishini ye-single-chip);kodwa-ke, ngokuboniswa kwe-LCD yobukhulu obukhulu noma enemibala, ngokuvamile Izothatha ingxenye enkulu yezinsiza noma ayikwazi ukulawula uhlelo lokulawula.Isibonelo, 320 × 240 256 umbala we-LCM uboniswa emidlalweni engu-20/umzuzwana (okungukuthi, izikhathi ezingu-20 kusekhondi elingu-1, izikhathi ezingu-20), kanye nedatha edluliselwa ngomzuzwana owodwa kuphela Inani liphezulu njengalokhu: 320 × 240 × 8 × 20 = 11.71875MB noma 1.465MB.Uma uchungechunge lwe-MCS51 olujwayelekile lwe-single -chip microcomputer lucutshungulwa, kucatshangwa ukuthi kusetshenziswa ngokuphindaphindiwe isiyalo se-MOVX ukuze udlulise le datha ngokuqhubekayo, cabangela isikhathi sokubala ikheli, okungenani amawashi angu-421.875mHz angaqedwa ukuze aqedele Ukudluliselwa kwedatha kubonisa inani elikhulu ledatha. ukucubungula.

Izinyathelo Zokugoqa Hlela lesi sigaba

Imodeli ye-LCDiyingxenye ehlanganisa amadivaysi e-Shanghai LCD nokulawula, isekethe yokushayela kanye nebhodi lomugqa PCB.Angakwazi ukuxhuma ngqo kukhompuyutha.Uma usebenzisa le moduli, ngaphezu kwezinyathelo zokuphepha lapho kusetshenziswa idivayisi yokubonisa i-LCD evamile, kufanele futhi ihlanganiswe.Naka izinto ezilandelayo ngesikhathi sokusebenzisa:

Ifilimu yokuzivikela yokwelapha

Kukhona ifilimu evikelayo ebusweni bedivayisi ye-LCD eqediwe kumojula efakiwe ukuvimbela indawo engaphezulu ekuhlobiseni.Ungayimbuli ngaphambi kokuphela komhlangano womshini, ukuze ungangcolisi noma ungcolise indawo yokubonisa.

Iphedi

Kungcono ukufaka iphedi cishe ngo-0.1mm phakathi kwemojuli nephaneli yangaphambili.Iphaneli kufanele futhi ihlale isicaba ngokuphelele.Iqinisekisiwe ukuthi ayikhiqizi ukuhlanekezela ngemva kokuhlanganiswa.Futhi uthuthukise ukusebenza kokuzamazama komhlaba.

Vimbela ngokuqinile ugesi omile

Isifunda sokulawula nokushayela kulemojula singamasekhethi e-CMOS ane-voltage aphansi kanye ne-micro-power, angena kalula nge-electrostatic, futhi umzimba womuntu ngezinye izikhathi ukhiqiza ambalwa ama-high-voltage static kagesi kagesi kagesi kagesi e-electrostatic, ngakho-ke ekusebenzeni, ukuhlanganisa, kanye nokusetshenziswa okusebenzayo Qaphela ukuvimbela ugesi omile ngokuqinile.kuze kube manje:

1) Ungathinti ukuhola kwangaphandle ngezandla zakho, ibhokisi lesekhethi nelensimbi ebhodini lesifunda.

2) Uma kufanele uxhumane ngokuqondile, gcina imojuli yomzimba womuntu inamandla afanayo noma ugaye kahle umzimba womuntu.

3) I-soldering iron esetshenziselwa ukushisela kufanele isekelwe kahle ngaphandle kokuvuza.

4) Ikhoni kagesi esebenzayo namanye amathuluzi kufanele abekwe kahle ngaphandle kokuvuza.

5) Ungasebenzisi i-vacuum vacuum cleaner ukuze uhlanze.Ngoba ikhiqiza ugesi omile oqinile.

6) Umoya owomile uzophinde ukhiqize ugesi omile.Ngakho-ke, umswakama wegumbi lokusebenza kufanele ube ngaphezu kuka-RH60%.

7) Kufanele kwakhiwe ama-resistors phakathi komhlaba, ibhentshi lokusebenzela, isihlalo, ishalofu, izinqola, namathuluzi okugcina amandla afanayo, ngaphandle kwalokho kuzokwenziwa nogesi omile.

8) Lapho ukhipha noma ubuyela esikhwameni sokupakisha noma endaweni enyakazayo, qaphela ukuthi ungaphehli ugesi omile.Ungashintshi noma ulahle amaphakheji okuqala ngokuthanda kwakho.

Ukuwohloka okungashintshi kuwumonakalo ongenakubuyiseleka.Qiniseka ukuthi unake futhi awunandaba.

Izinyathelo zokuqapha ngesikhathi sokusebenza komhlangano.

I-module iklanywe ngokucophelela futhi ihlanganiswe.Ungawucubunguli ngokuthanda kwakho futhi ulungise.

I-1) Ibhokisi lensimbi alikwazi ukuboshwa ngokuthanda futhi lihlakazwe.

2) Ungashintshi ukuma kwebhodi le-PCB ngokuthanda kwakho, izimbobo ezihlanganisiwe, imigqa kanye nezingxenye.

3) Ungaguquli ibha yokunamathisela enamathelayo.

4) Ungaguquli noma yimuphi ubakaki wangaphakathi.

5) Ungathinti, uwe, usonge, usonte imojuli.

ukushisela

Kumodule ye-welding yangaphandle kanye ne-interface circuit, ukusebenza kufanele kwenziwe ngokuhambisana nezinqubo ezilandelayo.

I-1) Izinga lokushisa lekhanda le-soldering iron lingaphansi kwama-280 ℃

2) Isikhathi sokushisela singaphansi kwama-3-4s

3) Izinto zokushisela: uhlobo olujwayelekile lwekristalu, indawo encibilikayo ephansi.

4) Ungasebenzisi i-acidic welding.

5) Ungadluli izikhathi ezi-3 zokushisela okuphindaphindiwe, futhi isikhathi ngasinye sidingeka ngokuphindaphindiwe sibe imizuzu emi-5/

Ukusetshenziswa nokugcinwa kwamamojula

1) Uma imojula isebenzisa amandla okufinyelela futhi inqamule amandla, kufanele yenziwe kushejuli.Okusho ukuthi, kufanele ufake izinga lesignali endaweni yamandla ephozithivu (5 ± 0.25V) ukuze ufake izinga lesiginali.Uma ufaka ileveli yesiginali ngaphambi kokuthi ukunikezwa kwamandla kuzinzile, noma ngemva kokunqanyulwa, isifunda esihlanganisiwe kumojuli izolimala futhi imojuli izolimala.

2) Imojula ye-matrix yamachashazi ingumgwaqo omkhulu -inombolo yedivayisi ye-LCD yokubonisa.Ukuhluka kwesibonisi, i-engeli yokubuka nezinga lokushisa, kanye ne-voltage yokushayela kuhlobene kakhulu.Ngakho-ke, kufanele ilungiswe kuze kube yilapho umehluko nombono omuhle kakhulu.Uma i-VEE iphezulu kakhulu, ngeke nje ithinte isibonisi, kodwa futhi ithinte impilo yedivayisi yokubonisa.

3) Uma usebenzisa umkhawulo ophansi webanga lokushisa elisebenzayo, impendulo ihamba kancane kakhulu.Lapho kusetshenziswa umkhawulo ongaphezulu webanga lokushisa elisebenzayo, yonke indawo yokubonisa izoba mnyama.Lokhu akonakele.Ibanga lokushisa lokubuyisela lingabuyela kokujwayelekile.

4) Cindezela ingxenye yesibonisi ngamandla, ezoveza isibonisi esingavamile.Inqobo nje uma ugesi uvaliwe, ungatholwa ngokuphinda ufinyelele.

I-5) Lapho i-liquid crystal display device noma ingaphezulu lemojula liyinkungu, ungasebenzi ukusebenza, ngoba impendulo yamakhemikhali e-electrode izokwenzeka ngalesi sikhathi ukukhiqiza ukunqanyulwa.

6) Izithombe ezisele zokusetshenziswa isikhathi eside elangeni nokukhanya okuqinile.

Isitoreji semojuli

Uma isitoreji sesikhathi eside (njengesingaphezu kweminyaka embalwa), sincoma izindlela ezilandelayo.

1) Faka iphakethe le-polyethylene (okungcono i-anti-static coating) bese uvala umlomo.

2) Isitoreji phakathi -10-+35 ° C.

3) Yibeke ebumnyameni ukuze ugweme ukukhanya okunamandla.

4) Ungalokothi ubeke noma yiziphi izinto phezulu.

5) Gwema ngokuqinile isitoreji ngaphansi kwezimo zokushisa/umswakama owedlulele.Kumele igcinwe ngaphansi kwezimo ezikhethekile.Ingabuye igcinwe ku-40 ° C, 85%RH, noma 60 ° C nangaphansi kuka-60% RH, kodwa akufanele idlule amahora angu-168.
