Kuyini ukukhanyisa LED? izinhlobo ukukhanyisa

Abakhiqizi zokukhiqiza ithelevishini tshela abasebenzisi njalo nge ubuchwepheshe obusha ukuthi ngcono ikhwalithi yesithombe yokudlulisela. Sekuyisikhathi eside Tindlelanchubo ukubuyisana izikrini TV futhi izakhi LED kahle yezinkampani ezinkulu. Muva nje, kucelwe umthombo kukhanya egqamile futhi soft futhi sihamba ekubonisaneni ephathekayo. Hlaziya kokufaneleka ngesinqumo esifana nalesi can futhi abasebenzisi ukukhanyisa bendabuko esekelwe LED, kodwa yebo, ebukeka ezikhanga kakhulu kwasemuva LED-izikrini TV. Lapho ngakho ngoba sigcwalisa nezinye zobuchwepheshe ithuba zisetshenziselwe ukuthuthukisa yaleli su.

Idivayisi ukukhanyisa

Ngaphakathi dalo of amamojuli ukusebenzisa kwasemuva asetshenziswa LED-afanayo lapho kungase kuhilele LED izinto ezimhlophe lowehlukile noma luminescence, ezifana RGB. Ibhodi yakhelwe ukuhlomisa matrix eziklanyelwe ukuhlanganisa idivayisi yenethiwekhi imodeli ethize. Ngokuvamile, ohlangothini lwesobunxele nezixhumi ibhodi ahlelwe, omunye enikeza amandla LED ukukhanya, kuyilapho abanye zenzelwe ukulawula ukucushwa yokusebenza yayo. Futhi ngenxa amamojuli LED ukusebenzisa umshayeli ekhethekile, umsebenzi okuyinto lihlotshaniswa isilawuli.

Ngesimo eseqedile LED strip siqukethe uchungechunge izibani miniature ezixhunywe ngeenqhema 3 izicucu. Ngokuqinisekile, abakhiqizi musa batusa liphazamisane kudivayisi opholile ezinjalo, kodwa bangase ngokomzimba mfushane noma, Ngakolunye uhlangothi, wenze idivayisi eside uma uthanda. Futhi, iyunithi esibukweni LED-kwasemuva inikeza ikhono ulungise ukukhanya, igcina sokuqala bushelelezi futhi ifakwe isivikelo voltage.

Ukwahlukanisa kwasemuva kulungiselelwa uhlobo

Kunezindlela ezimbili ukuhlanganisa okukhanyisa LED - eqondile sekupheleni. Ukulungiselelwa lokuqala kudinga ukuthi afanayo uzobe esemva okucaciswe luketshezi panel. Indlela yesibili ivumela ukudala mncane kakhulu panel izikrini futhi ubizwa ngokuthi Edge-LED. Kulokhu, ukubekwa yemigoqo ethile eminyangweni kahulumeni emhlabeni azungezwe ohlangothini engaphakathi isibonisi. Ngakho distribution umfaniswano LED Kwenziwa esebenzisa panel okuyinto ngokufanele ngemuva LCD - ngokuvamile lolu hlobo kwasemuva LED-screen isetshenziswa ukuthuthukiswa kumadivayisi eselula. Amalungu kwasemuva ngqo abonisa yi qualitative ka luminescence, okuyinto ibangelwa inombolo enkulu LED kanye Ukufiphala wendawo ukunciphisa umbala streaks.

Isicelo se-lwenkanyiso LED

Umthengi isilinganiso ungathola lobu buchwepheshe in the amamodeli we-Sony TV, LG Samsung, kanye Kodak imikhiqizo Nokia. Yiqiniso, i-LED baye zande, kodwa ukwenza imifanekiso yalezi abakhiqizi kuyagcinwa izinguquko qualitative bebheke ekuthuthukiseni izimfanelo umthengi ngalesincumo. Enye yezinkinga eziyinhloko ezibhekene Abaklami ukusekela ukusebenza kwesikrini ezinezici elikhulu ngokuya elangeni. Futhi, LED LED-kwasemuva esanda ngcono ngokuya okwandisa umehluko. Uma sikhuluma intuthuko ohlangothini isakhiwo esikrinini, bese kukhona nokuncipha okukhulu enanini ukushuba we panel, kanye ukuhambisana ne screen ebanzi. Kodwa ukuhlala izinkinga ezingaxazululeki. LED abakwazi ukuthuthukisa ngokugcwele amakhono abo inqubo ukubonisa ukwaziswa. Nokho, lokhu akazange akuvimbele ukukhandwa LED-ubuchwepheshe azixoshe CCFL-nezibani ancintisane isizukulwane esisha plasma zesikrini.

impumuzo umphumela

Amamojuli esekelwe diodes ukukhanya-likhipha Ziningi amakhono ukunikeza imiphumela ehlukile. Kulesi sigaba ukuthuthukiswa abakhiqizi ubuchwepheshe abakhuthalele usebenzisa izixazululo ezimbili stereoscopic. Eyokuqala kunikeza ukuphambuka emincane ye fluxes emisebeni ngokusekelwa umphumela umumo womsebenzi. Umsebenzisi ukwazi ukubona umphumela ngokuhamba wokubuka usebenzisa izibuko noma ngaphandle kwabo, okungukuthi, e holography imodi. Umthelela sesibili sihlanganisa displacement of yokucucuza elikhanyayo okuyinto kudedela izibani LED-asibonisayo indlela predetermined ku okucaciswe luketshezi izingqimba. Sebenzisa lobu buchwepheshe kungenziwa kuhlangene 2D-futhi 3D-nezakhiwo ngemva kokuguquka ezifanele noma ikhodi. Nokho, ngokuphathelene inhlanganisela kungenzeka ngemifanekiso ngakuthathu kusukela backlights LED abayi ngokushelela.

Ihambisana nawo 3D ubuchwepheshe

Asinakusho ukuthi isikrini LED-backlit, zikhona izinkinga ezibucayi nokuxhumana ifomethi 3D, kodwa endleleni kahle umbukeli a "isithombe" ezinjalo zidinga izibuko ezikhethekile. Enye yezindawo ethembisayo kwalentuthuko kukhona izibuko stereo. Ngokwesibonelo, onjiniyela NVIDIA ukhiphe eminyakeni embalwa edlule-yesivalo 3D izibuko nge okucaciswe luketshezi lens. Ukuze deflecting ukukhanya imishayo LCD LED-kwasemuva isikrini sihlinzekela ukusetshenziswa nokwehlukana izihlungi. Kulokhu, amaphuzu abazenzi ngaphandle luhlaka ekhethekile, ngesimo tape. lens Embedded siqukethe nezinto eziningi ayevumela afanayo LED, okuyinto ukuqonda ulwazi ngedivayisi control.

Izinzuzo kwasemuva

Uma uqhathaniswa nezinye izinketho ukukhanyisa, LED kakhulu ukuthuthukisa izinga zesikrini umthengi ithelevishini. Ngokuyinhloko ngcono izici umfanekiso ngqo - lokhu kuphumela okwandisa Ngokuphambene nombala ukukhiqizwa kabusha. The esiphezulu umbala izinga ukucutshungulwa spectrum inikeza RGB--matrix. Ngaphezu kwalokho, LED-kwasemuva ezahlukene low power ukusetshenziswa. Futhi izuzwe ugesi ukusetshenziswa nokwehlisa 40% kwezinye izimo. Futhi uzinake ukuthi kungenzeka esikhiqiza ultrathin zesikrini, okuyinto ngesikhathi esifanayo abe nesisindo ongaphakeme.

amaphutha

Amalungu TV akhona kwasemuva LED bagxekwa imiphumela yabo oluyingozi blue-violet emisebeni phezu kwamehlo. Futhi bluish nasemkhakheni "isithombe" kakhulu siphendukezela yemvelo umbala ukukhiqizwa kabusha. Nokho, izinguqulo TV nge high -resolution LED-kwasemuva sikrini cishe akukho ukukhubazeka okunjalo. Kodwa kukhona izinkinga wokwengamela ukukhanya, lapho ishayela bazibandakanye nobubanzi kwezwi. Kulezo zimo, ungase uphawule kulokolokoza esibukweni.

isiphetho

Kuze kube manje, amamodeli ingxenye TV nge LED-ubuchwepheshe isakhasa. Nakuba umthengi Kuhlola amathuba nesithunzi, elikwaziyo ukunikeza isixazululo ezintsha. Kufanele kuqashelwe ukuthi bokwenza tekusebenta possessed LED LED-izibani, ungayididanisi abasebenzisi izindleko eziphakeme. Ochwepheshe abaningi, lokhu yikona kubhekwa kube umgoqo omkhulu lo popularization ubuchwepheshe. Nokho, liyini ikusasa LED zisekhona ethembisa, njengoba izindleko zabo uzokwehla njengoba funa iyakhula. Parallel kule nezinye ngcono izinga ukukhanyisa, elibuye kwandisa ukukhanga sipho.
