Imodyuli ye-LCD

Iimpawu zobugcisa

I-LCM yimveliso ye-LCD ehlanganisiweyo ephezulu xa kuthelekiswa neglasi.Kubukhulu obuncinciUmboniso we-LCD, I-LCM ingaba lula ngakumbi ukudibanisa kwii-microcontrollers ezahlukeneyo (ezifana noomatshini be-single-chip);nangona kunjalo, ubungakanani obukhulu okanye umbala we-LCD wokubonisa, ngokubanzi Iyakuthatha indawo enkulu yezibonelelo okanye ayikwazi ukulawula inkqubo yokulawula.Ngokomzekelo, i-320 × 240 256 umbala we-LCM uboniswa kwimidlalo engama-20 / okwesibini (oko kukuthi, amaxesha angama-20 kwi-1 yesibini, amaxesha angama-20), kwaye idatha idluliselwe kuphela ngomzuzwana omnye Ubuninzi buphezulu: 320 × 240 × 8 × 20 = 11.71875MB okanye 1.465MB.Ukuba umgangatho we-MCS51 uchungechunge lwe-single-chip microcomputer lucutshungulwa, ucinga ngokuphindaphindiweyo ukusebenzisa umyalelo we-MOVX ukuhambisa ngokuqhubekayo ezi datha, qwalasela ixesha lokubala idilesi, ubuncinane iiwotshi ze-421.875mHz zingagqitywa ukugqiba Ukuhanjiswa kwedatha kubonisa inani elikhulu ledatha. ukuqhubekeka.

Izilumkiso zokuSonga Hlela lo mhlathi

Imodyuli ye-LCDlicandelo elihlanganisa izixhobo LCD Shanghai kunye nolawulo, ukuqhuba isekethe kunye nebhodi line PCB.Uyakwazi ukudibanisa ngqo kwikhompyuter.Xa usebenzisa le modyuli, ukongeza kumanyathelo okhuseleko xa isixhobo sokubonisa i-LCD ngokubanzi sisetyenziswa, kufuneka zidityaniswe.Nika ingqalelo kwezi zinto zilandelayo ngexesha lokusetyenziswa:

Ifilimu ekhuselayo yonyango

Kukho ifilimu ekhuselayo ebusweni besixhobo se-LCD esigqityiweyo kwimodyuli efakwe ukuthintela umphezulu wokuhlobisa.Musa ukuyityhila ngaphambi kokuphela kokuhlanganiswa komatshini, ukuze ungangcolisi okanye ungcolise indawo yokubonisa.

Iphedi

Kungcono ukufaka iphedi malunga ne-0.1mm phakathi kwemodyuli kunye nephaneli yangaphambili.Indawo yolawulo kufuneka ihlale ithe tyaba ngokupheleleyo.Kuqinisekisiwe ukuba ayivelisi ukuphazamiseka emva kokuhlanganisana.Kwaye uphucule ukusebenza kwe-seismic.

Ukuthintela ngokuthe ngqo umbane ongatshintshiyo

Ulawulo kunye nesekethe yokuqhuba kwimodyuli iphantsi-i-voltage kunye ne-micro-power CMOS circuits, ezingenwa lula yi-electrostatic, kunye nomzimba womntu ngamanye amaxesha uvelisa ezimbalwa eziphezulu -voltage static zombane ombane wombane wombane we-electrostatic, ngoko ekusebenzeni, ukudibanisa, kunye nokusetyenziswa ekusetyenzisweni Qaphela ukuthintela umbane osisigxina ngokungqongqo.ukuya koku kuphela:

1) Musa ukuthintela ukukhokela kwangaphandle ngezandla zakho, isiphaluka kunye nebhokisi yentsimbi kwibhodi yesiphaluka.

2) Ukuba kufuneka uqhagamshelane ngokuthe ngqo, gcina imodyuli yomzimba womntu inamandla afanayo okanye ucole kakuhle umzimba womntu.

3) Intsimbi ye-soldering esetyenziselwa i-welding kufuneka ibekwe kakuhle ngaphandle kokuvuza.

4) I-cone yombane esebenzayo kunye nezinye izixhobo kufuneka zibekwe kakuhle ngaphandle kokuvuza.

5) Musa ukusebenzisa i-vacuum vacuum cleaner yokucoca.Kuba ivelisa umbane ongashukumiyo owomeleleyo.

6) Umoya owomileyo uya kuvelisa umbane ongatshintshiyo.Ngoko ke, ukufuma kwegumbi lokusebenza kufuneka kube ngaphezu kwe-RH60%.

I-7) I-resistors kufuneka yenziwe phakathi komhlaba, i-workbench, isihlalo, i-shelf, iinqwelo, kunye nezixhobo zokugcina amandla afanayo, ngaphandle koko umbane ongatshintshiyo uya kuveliswa.

8) Xa ususa okanye ubuyela kwisikhwama sokupakisha okanye indawo yokuhamba, qaphela ukuvelisa umbane omileyo.Musa ukutshintsha okanye ulahle ipakethe yokuqala ngokuthanda kwakho.

Ukophuka okumileyo ngumonakalo ongenakubuyiselwa.Qiniseka ukuba ubeke ingqalelo kwaye ungakhathali.

Izilumkiso ngexesha lokusebenza kwendibano.

Imodyuli iyilwe ngononophelo kwaye idityanisiwe.Musa ukuyiqhuba ngokuthanda kwakho kwaye uyilungise.

I-1) Ibhokisi yensimbi ayinakubanjwa ngokuthanda kwaye ichithwe.

2) Musa ukuguqula imilo yebhodi yePCB ngokuthanda, imingxuma edibeneyo, imigca kunye namacandelo.

3) Musa ukuguqula ibha yokubambelela edibeneyo.

4) Musa ukuguqula nayiphi na i-bracket yangaphakathi.

5) Sukuchukumisa, uwa, usonge, ujije imodyuli.

ukuwelda

Kwimodyuli ye-welding yangaphandle kunye nesekethe ye-interface, ukusebenza kufuneka kwenziwe ngokuhambelana nezi nkqubo zilandelayo.

1) Ubushushu bentloko yentsimbi yokuthambisa bungaphantsi kwama-280 ℃

2) Ixesha le-Welding lingaphantsi kwe-3-4s

3) Izinto ze-Welding: uhlobo oluqhelekileyo lwekristale, indawo ephantsi yokunyibilika.

4) Musa ukusebenzisa i-acidic welding.

5) Ungagqithisi amaxesha ama-3 ngokuphindaphindiweyo kwe-welding, kwaye ixesha ngalinye lifuneka ngokuphindaphindiweyo ukuba libe yimizuzu emi-5 /

Ukusetyenziswa kunye nokugcinwa kweemodyuli

I-1) Xa imodyuli isebenzisa amandla okufikelela kwaye ikhuphe amandla, kufuneka yenziwe kwishedyuli.Oko kukuthi, kufuneka ufake inqanaba lesignali kumandla afanelekileyo (5 ± 0.25V) ukungena kwinqanaba lesignali.Ukuba ufaka umgangatho wesignali ngaphambi kokuba unikezelo lwamandla luzinzile, okanye emva kokuqhawula, isiphaluka esidibeneyo kwimodyuli siya konakala kwaye imodyuli iya konakala.

2) Imodyuli ye-matrix yechaphaza yindlela enkulu-inombolo ye-LCD yokubonisa isixhobo.Umahluko wokubonisa, i-angle yembono kunye nobushushu, kunye nombane wokuqhuba unxulumene kakhulu.Ngoko ke, kufuneka ilungiswe kude kube yeyona nto ingcono kunye nembono.Ukuba i-VEE iphezulu kakhulu, ayiyi kuchaphazela kuphela umboniso, kodwa ichaphazela ubomi besixhobo sokubonisa.

I-3) Xa usebenzisa umda ophantsi womgangatho wokushisa osebenzayo, impendulo icotha kakhulu.Xa umda ophezulu womgangatho wokushisa osebenzayo usetyenziswa, yonke indawo yokubonisa iya kuba mnyama.Oku ayonakaliswanga.Uluhlu lweqondo lokushisa lokubuyisela lungabuyela ngokuqhelekileyo.

4) Cinezela inxalenye yokubonisa ngamandla, eya kuvelisa umboniso ongaqhelekanga.Logama nje umbane ucinyiwe, unokufunyanwa kwakhona ngofikelelo kwakhona.

5) Xa isixhobo sokubonisa i-crystal liquid okanye umphezulu wemodyuli yinkungu, ungasebenzi ukusebenza, kuba impendulo yekhemikhali ye-electrode iya kwenzeka ngeli xesha ukuvelisa ukuqhawula.

I-6) Imifanekiso eseleyo yokusetyenziswa kwexesha elide elangeni kunye nokukhanya okunamandla.

Ukugcinwa kwemodyuli

Ukuba ixesha elide (elifana neminyaka embalwa) yokugcina, sincoma iindlela ezilandelayo.

1) Beka i-pocket polyethylene (ngokukhethekileyo i-anti-static coating) kwaye utywine umlomo.

2) Ukugcinwa phakathi kwe -10-+35 ° C.

3) Yibeke ebumnyameni ukuze ugweme ukukhanya okunamandla.

4) Ungaze ubeke naziphi na izinto phezu komhlaba.

I-5) Gwema ngokungqongqo ukugcinwa phantsi kweemeko ezinzulu zokushisa / ukufuma.Kufuneka igcinwe phantsi kweemeko ezizodwa.Iyakwazi ukugcinwa kwi-40 ° C, i-85% RH, okanye i-60 ° C kwaye ingaphantsi kwe-60% RH, kodwa akufanele idlule iiyure ze-168.
