Ipuleti lomhlahlandlela wokukhanya we-LED
Indima yepuleti lomhlahlandlela wokukhanya ukuqondisa indlela yokukhanya ehlakazekayo ukuze kuthuthukiswe ukukhanya kwephaneli nokuqinisekisa ukufana kokukhanya kwephaneli.Izinga elihle lepuleti lomhlahlandlela wokukhanya linethonya elikhulu kupuleti le-backlight.Ngakho-ke, ukuklama nokukhiqizwa kwepuleti lomhlahlandlela wokukhanya epuleti le-backlight elikhanyiswe onqenqemeni Kungobunye bobuchwepheshe obubalulekile.
Ipuleti eliqondisayo elikhanyayo lenziwa ngokusebenzisa indlela yokubumba umjovo ukuze ucindezele i-propylene ibe ipuleti elinendawo ebushelelezi.Bese, kusetshenziswa into ebonisa ukukhanya okuphezulu nokumunca okungakhanyi, iphoyinti lokusabalalisa liphrintwa endaweni engaphansi yepuleti lomhlahlandlela wokukhanya ngokuphrinta isikrini.Isibani esibandayo se-cathode fluorescent sitholakala epuleti lomhlahlandlela wokukhanya.Engxenyeni ewugqinsi yohlangothi, ukukhanya okukhishwa yishubhu le-cathode elibandayo kudluliselwa ekugcineni okuncanyana ngokuzindla.Uma ukukhanya kushaya iphoyinti lokusabalalisa, ukukhanya okubonisiwe kuzosabalalisa kuma-engeli ahlukahlukene, bese kucekela phansi izimo zokubonisa futhi kukudubula kuphume ngaphambili kwepuleti lomhlahlandlela wokukhanya.
Amaphoyinti okusabalalisa amancane futhi aminyene amasayizi ahlukahlukene angenza ipuleti likamhlahlandlela wokukhanya likhiphe ukukhanya ngokulinganayo.Injongo yepuleti elikhanyayo ukukhombisa ukukhanya okuveziwe endaweni engaphansi kubuyele epuleti lomhlahlandlela wokukhanya ukuze kuthuthukiswe ukusebenza kahle kokusetshenziswa kokukhanya.
EL ipuleti elibandayo
Ipuleti lomhlahlandlela wokukhanya lingahlukaniswa ngohlobo lokuphrinta kanye nohlobo olungaphrinti ngokuya ngokugeleza kwenqubo ehlukile.Uhlobo lokuphrinta luwukusebenzisa ukukhanya okuphezulu kanye nezinto ezingakumunyi ukukhanya epuleti le-acrylic.Indawo engezansi yepuleti yomhlahlandlela wokukhanya iphrintwa ngendingilizi noma isikwele ngokuphrinta isikrini.Iphuzu lokusabalalisa.Uhlobo olungaphrinteki lusebenzisa isikhunta esinembayo ukwenza ipuleti lomhlahlandlela okhanyayo kunqubo yokubumba umjovo, okwengeza inani elincane lezinto eziyimbudumbudu ezinezinkomba ezihlukile zokuphinda zikhanye kokubalulekile kwe-acrylic ukuze kwakheke ngokuqondile amaqhuqhuva amancane asabalaliswe kakhulu, asebenza njengamachashazi.
Indlela yokuphrinta ayisebenzi njengeyona ndlela yokungaphrinti.Indlela yokungaphrinti inomphumela omuhle kakhulu, inombolo encane yabasebenzisi, isivinini esikhulu nokusebenza kahle okuphezulu, kodwa umkhawulo wezobuchwepheshe uphezulu kakhulu.Kudingeka ukwazi ukubumba umjovo ngokunemba, ukubumba okunembayo, okokubona kanye nobunye ubuchwepheshe.Njengamanje, kunezinkampani ezintathu emhlabeni ezinekhono kulokhu, futhi imakethe ilawulwa yilaba abathathu.Ngokwezibalo ze-Taiwan IEK ngo-2002, amasheya emakethe yi-Asahi Kasei (35%), iMitsubishi (25%), i-Kuraray (18%), kanye nokunye.
Iningi lazo amapuleti aqondisayo alula akhiqizwa izindlela zokunyathelisa.Ngasikhathi sinye, u-Asahi Kasei futhi ungumnikezeli omkhulu wezinto zengilazi eziphilayo, ezithatha ngaphezu kwe-50% yemakethe.Futhi iMitsubishi ihamba phambili emhlabeni mayelana nokukhiqizwa kwe-plexiglass kanye nobuchwepheshe bokucubungula.Njengamanje, abakhiqizi abaningi basekhaya basasebenzisa amapuleti omhlahlandlela wokukhanya aphrintiwe njengezingxenye zomhlahlandlela wokukhanya.Amapuleti omhlahlandlela wokukhanya aphrintiwe anezinzuzo zezindleko eziphansi zokuthuthukiswa kanye nokukhiqizwa okusheshayo.Amapuleti omhlahlandlela wokukhanya angaphrintiwe anzima ngokwezobuchwepheshe, kodwa anokukhanya okuhle kakhulu.
