Led Bonisa iziseko
Umboniso we-LED ngumboniso wepaneli eyisicaba, eyenziwe ngeepaneli zemodyuli ezincinci ezininzi ze-LED, ezisetyenziselwa ukubonisa umbhalo, imifanekiso, ividiyo, iimpawu zevidiyo kunye nezinye izixhobo zolwazi ezahlukeneyo.
Isetyenziswa ikakhulu kwintengiso yangaphandle yangaphakathi, umboniso, umdlalo, imvelaphi yokusebenza kunye nezinye iinjongo. Ngokuqhelekileyo zifakwe kwiindawo zorhwebo, iifacade zokwakha, iindlela zendlela, iindawo zoluntu, isiteji sangaphakathi, amagumbi enkomfa, ii-studios, iiholo zesidlo, amaziko omyalelo kunye nezinye iindawo, zidlala indima ekuboniseni.
Ⅰ. umgaqo wokusebenza wokuboniswa kwe-LED
Umgaqo osisiseko wokusebenza wokuboniswa kwe-LED kukuskena okuguquguqukayo. Ukuskena okunamandla kwahlulwe kumgca wokuskena kunye nekholamu yokuskena iindlela ezimbini, indlela esetyenziswa ngokuqhelekileyo kukuskena ngelayini. Ukuskena komgca kwahlulwe kumgca we-8 kunye ne-16 yokuskena.
Kwimowudi yokukhangela umgca wokusebenza, isiqwenga ngasinye se-matrix ye-dot ye-LED sineseti yesekethe ye-column drive, i-column drive circuit kufuneka ibe ne-latch okanye irejista yokutshintsha, esetyenziselwa ukutshixa umxholo oza kuboniswa kwidatha yemowudi yegama. Kwindlela yokukhangela umgca wokusebenza, umgca ofanayo we-LED dot-matrix isiqwenga segama elifanayo izikhonkwane zokulawula umgca zixhunywe ngokuhambelana kumgca, i-8 iyonke imigca, kwaye ekugqibeleni idibaniswe kwisekethe yokuqhuba umgca; Umgca wesekethe ye-drive kufuneka ube ne-latch okanye irejista yokutshintsha, esetyenziselwa ukutshixa isignali yokuskena umgca.
Umboniso we-LED we-column drive circuit kunye ne-line drive circuit zisetyenziswa ngokubanzi ukulawula i-microcontroller, i-microcontroller esetyenziswa rhoqo yi-MCS51 series. Umxholo wesiboniso se-LED ngokuqhelekileyo ugcinwe ngendlela yemo yegama kwimemori yedatha yangaphandle ye-microcontroller, igama elithi imo yinombolo ye-binary ye-8.
Ⅱ. ulwazi olusisiseko lomboniso weLed
1, yintoni i-LED?
I-LED sisishunqulelo se-diode ekhupha ukukhanya (LIGHT EMITTING DIODE), ngolungiselelo lwe-diode ekhupha ukukhanya eyenziwe sisixhobo sokubonisa. Umzi-mveliso wokubonisa uthe i-LED ibhekisa kwi-LED inokukhupha amaza abonakalayo.
2, yintoni umboniso we-LED?
Ngeendlela ezithile zolawulo, uluhlu lwesixhobo se-LED luqulunqwe sisikrini sokubonisa.
3, yintoni imodyuli yokubonisa i-LED?
Kukho iisekethe kunye nesakhiwo sofakelo ukumisela, kunye nemisebenzi yokubonisa, inokuqondwa ngokusebenzisa umsebenzi wokubonisa indibano elula yeyunithi esisiseko.
4, Yintoni imodyuli yokubonisa i-LED?
Idityaniswe inani leepikseli zokubonisa, ezizimeleyo ngokwesakhiwo, zinokwenza eyona yunithi incinci yomboniso we-LED. Eqhelekileyo 8 * 8, 8 * 7, njl.
5. Yintoni inowuthi yepixel (inowuthi yechaphaza)?
Umgama osembindini phakathi kweepikseli ezimbini ezikufutshane, i-pitch encinci, imfutshane umgama obonakalayo. Ishishini lidla ngokufinyezwa ngo-P ukubonisa isithuba samanqaku.
6, Yintoni pixel density?
Ikwaziwa kwakhona njengoxinaniso lwamachaphaza, idla ngokubhekisa kwinani leepikseli ngemitha yesikwere kwisibonisi.
7, Yintoni ukukhanya okuqaqambileyo?
Indawo yeyunithi yokubonisa i-LED ekhutshwe ngamandla okukhanya, iyunithi yi-CD / imitha yesikwere, ibekwe ngokulula ngumboniso wemitha yesikwere ekhutshwe ngamandla okukhanya;
8, yintoni ukukhanya kwesiboniso se-LED?
Ukukhanya komboniso we-LED kubhekiselele ekusebenzeni okuqhelekileyo komboniso, indawo yeyunithi yokubonisa yobukhulu obukhanyayo, iyunithi yi-cd / m2 (okt, zingaphi ii-cd zobukhulu obukhanyayo ngemitha yesikwere yendawo yomboniso.
11, Yintoni inqanaba elingwevu?
Umgangatho ongwevu wesiboniso se-LED sisalathisi esibonisa umgangatho womfanekiso wesiboniso. Inqanaba elimpunga lesikrini sevidiyo lihlukaniswe ngamanqanaba angama-64, amanqanaba e-128, amanqanaba angama-256, amanqanaba angama-512, amanqanaba e-1024, amanqanaba angama-2048, amanqanaba angama-4096 njalo njalo. Ukuphakama kwenqanaba le-grayscale, ngokucacileyo umgangatho womfanekiso, umgangatho we-grayscale jikelele we-256 okanye ngaphezulu, umehluko wesithombe awukhulu kakhulu.
12, yintoni i-dual-color, pseudo-color, full-color display?
Ngokusebenzisa imibala eyahlukeneyo yokukhanya-emitting diode inokuqulunqwa ngemiboniso eyahlukeneyo, umbala ombini uqulunqwe ngombala obomvu, oluhlaza okanye otyheli-luhlaza emibini, umbala ongeyonyani wenziwa ngombala obomvu, omthubi-luhlaza, oluhlaza okwesibhakabhaka ngemibala emithathu eyahlukileyo, epheleleyo. -umbala wenziwa ngombala obomvu, oluhlaza ococekileyo, oluhlaza okwesibhakabhaka ngemibala emithathu eyahlukeneyo.
13, yintoni moire?
Kumsebenzi wokudubula we-LED egcwele umbala ogcweleyo, isikrini sokubonisa i-LED kuya kuba ne-ripples yamanzi engaqhelekanga, ezi zixhobo zamanzi kwi-physics zibizwa ngokuba yi "moiré".
14, yintoni i-SMT, yintoni i-SMD?
I-SMT yitekhnoloji exhonywe phezulu (i-SURFACE MOUNTED technology ngokufutshane), okwangoku yeyona teknoloji idumileyo kunye nenkqubo kushishino lweendibano zombane; I-SMD sisixhobo esixhonywe phezulu (isixhobo esifakwe kumphezulu ngokufutshane).
Umboniso we-LED luhlobo olutsha lwemithombo yeendaba ebonisa ulwazi, lulawulo lwemowudi yokubonisa i-diode ekhanyayo yesikrini somboniso wephaneli ecaba, ingasetyenziselwa ukubonisa okubhaliweyo, imizobo kunye nezinye iintlobo zolwazi olungatshintshiyo kunye noopopayi, ividiyo kunye nezinye iintlobo ulwazi oluguquguqukayo, umboniso we-elektroniki we-LED usete iteknoloji ye-microelectronics, iteknoloji yekhompyutha, ukusetyenzwa kolwazi kwelinye, kunye nemibala eqaqambileyo, uluhlu olubanzi oluguquguqukayo, ukukhanya okuphezulu, ubomi obude, obuzinzileyo kunye nokuthembeka, njl. Izinto eziluncedo, ezisetyenziswa ngokubanzi kumajelo orhwebo, imarike yokusebenza kwenkcubeko, iindawo zemidlalo, ukusasazwa kolwazi, ukukhutshwa kweendaba, ukurhweba ngezibambiso, njl., kunokuhlangabezana neemfuno zeendawo ezahlukeneyo. Ngokombala wesiseko sombala unokwahlulwa ube ngumboniso wombala omnye kunye nomboniso ogcweleyo wombala.
