Abaningi abakaze bavumelane ngokugcwele nomqondo wokuthi izikhathi zokuqapha kanye namathelevishini, ngokusekelwe esimisweni se-electron-beam yesakhiwo sokwakhiwa kwezithombe, sahlala yindawo eyedlule. Kungenzeka ukuthi eminyakeni eyi-12 bayokhunjulwa kuphela kwizifundo zomlando. Sonke manje siphila esikhathini lapho eziningi izikrini kumadivayisi wevidiyo zisekelwe ebuchwepheshe bekristal. Ama-TV, abaqaphi bekhompiyutha , izikrini zefoni nomakhalekhukhwini namakhamera - lokhu akulona uhlu oluphelele lamadivaysi asebenzisa i-TFT. Mhlawumbe manje, ngisho nabantu asebekhulile abamangazi ngesikrini esibucayi, esibizwa ngokuthi i-crystal crystal noma i-LCD - kusukela ngesiNgisi. Ukuboniswa kwe-crystal crystal . Noma kunjalo, maduzane ungase uzwe inkulumo ethi "i-monitor eyinqaba" kaningi. Naphezu kobuciko beli gama, abaningi baye bajwayele. Ngakho, abaqaphi be-Oled basakazwa ngenkuthalo kuthelevishini; Emasilons of communication ephathekayo, amamodeli amasha wezingcingo eziboniswayo ngokusebenzisa lolu buchwepheshe; Emakhasini nasemakhasini e-Intanethi kuqhathaniswa kakade yisikhathi (kunzima ukukholelwa) izikrini ze-LCD kanye nabaqashile abafakiwe. Ngakho-ke, ukuze ufunde ukuthi kunomqapha oleliwe, akudingekile ukufunda izibuyekezo futhi ulandele amanoveli emakethe.
Ikusasa Namuhla
Nakuba ukuboniswa kwe-Oled kuvame ukuvezwa njengento entsha emakethe yesikrini, kuhle kakhulu njenge-TFT. Okungenani izimiso zokuphathwa kwe- matrix zifana kakhulu. Kuyini umqapha oled? Isifushaniso sakhiwa kusukela ezincwadini zokuqala zamazwi angamaNgisi amagama e-Organic Light Emitting Diode - i-diode ekukhanyeni okukhanya okuphilayo. Uma uqhathanisa i-Monitor ye-Oled ne-LCD (i-crystal liquid), khona-ke i-matrix yayo ihlanganiswa ngamakhemikhali akhethekile asemvelo, ekwazi ukukhanya ngaphansi kwethonya lombane kagesi. Kodwa ekugcineni, ngokuphambene nalokho, amangqamuzana ayenziwe ngezinto ezingavamile futhi angeke akhanyise ngokwawo. I-voltage input ingashintsha kuphela ukuma kwendawo yesikristali ngayinye esitokisini ngokunyuka noma ukunciphisa ukukhanya okukhanya okuvela ohlelweni lokubuyiselwa emuva (izibani zamacathode ezibandayo noma ama-LED) asekugcineni komthamo.
Asizange sikhumbule ngokungafani ukufana kwezixazululo ezimbili. Iqiniso liwukuthi basebenzisa uhlelo olufanayo lokulawula: i-transistors efanayo, ilogi efanayo. Ngaphandle kokungabaza, ubuchwepheshe be-Oled ngeke buvele ngaphandle kokubukwa kwe- LCD.
Izici
Enye yezinzuzo zobuchwepheshe obusha ukungabikho kokubuyiselwa emuva. Kuzobukeli bendabuko be-TFT, kunenkinga yokufaniswa kokukhanya kwesikrini okubangelwa ubuqili bokubekwa kwe-backlight (noma ababusi be-diode). Kuyinto engasizi ngalutho kwezomnotho ukwenza indawo ekhanyayo yonke imithwalo, kanti nanoma yiluphi elinye ilungiselelo ukuhwebelana phakathi kokufana kanye nentengo / umnotho. I-Oled isemthethweni ngaphandle kwalesi sici: ukukhanya ngisho, umbala omnyama ujulile futhi ugcwele, njengoba kufanele.
Inzuzo elandelayo yi-angles enhle kakhulu yokubukela: ukuphazamiseka okudumile nokubukwa kombono akukho ngokuphelele.
Ubukhulu beqapha babube buncane kunelezo zemibukiso ene- LED emuva, futhi uhlelo lokulawula lwalungelula (ekugcineni umuntu angakhohlwa nge-PWM).
Mhlawumbe ukuhlukunyezwa kuphela okuhlobene nokuphila komsebenzi omfishane - ama-diode asanda kuphuma. Kodwa-ke, ukuziphatha okubizayo nokuguquka kwezizukulwane zabaqaphi kuyashesha kakhulu, ngakho akufanele ukhathazeke ngakho.
