Ukukhanya kwe-LED backlight kubhekiselele ekusebenziseni ii-LEDs (ii-diode ezikhupha ukukhanya) njengomthombo we-backlight we-liquid crystal display, ngelixa umboniso we-LED backlight ngumthombo we-backlight we-crystal display ephuma kwityhubhu yokukhanya ebandayo ye-CCFL (efana nezibane ze-fluorescent). ) kwi-LED (i-diode ekhupha ukukhanya).Umgaqo wokucinga wekristale yolwelo unokuqondwa ngokulula njengenyaniso yokuba amandla ombane angaphandle asetyenzisiweyo ukuphambukisa iimolekyuli zekristale zolwelo ziya kukuthintela ukungafihli kokukhanya okukhutshwe sisibane esingasemva njengesango, kwaye emva koko kuveliswe ukukhanya kwizihluzi zemibala eyahlukileyo. imibala ukwenza umfanekiso.

Ukukhanya okukhanyayo kwe-LED ngasemva

Isibane esikhanyisa umva se-LED kukulungiselela ukuba i-LED iyafa kumda wesikrini se-LCD, kwaye emva koko ifanise ipleyiti yesikhokelo sokukhanya, ukuze xa imodyuli yokukhanya kwe-LED ikhupha ukukhanya, ukukhanya okuphuma kumda wesikrini kudluliselwe indawo esembindini yesikrini ngepleyiti yesikhokelo sokukhanya., Ukuze isixa lilonke backlight, ukuvumela LCD screen ukubonisa imifanekiso.

Uphuhliso lwe-Edge-lit LED backlight

Ngophuhliso oluqhubekayo lwetekhnoloji, i-backlight ye-LED yecala iya kukhula ukusuka kwi-LED enye kumacala aphezulu nangaphantsi ukuya kwi-LED yokugqibela enecala elinye.Ngokuqhelekileyo, enye i-LED backlit TV kumacala omabini e-32 "enokubonwa kwimarike isebenzisa malunga ne-120 ukuya kwii-LED ze-150. Ukuba ukukhanya kwe-TV kuguqulwe kwi-LED enye, inani le-LED lingancitshiswa libe yi-80-100 ( Okunokuthi ekugqibeleni kuncitshiswe Inani le-LED lixhomekeke kwi-teknoloji ye-brand) Ukuba iteknoloji ihambelana, kwixesha elizayo elibonakalayo, i-LED enye iya kuguqulwa ukusuka kwicala elide (phezulu okanye phantsi) ukuya kwicala elifutshane (ekhohlo okanye ekunene ) Olu hlobo lotshintsho luya kusebenzisa i-LED encinci Inani lamasuntswana.

Ukongezwa kobomi

Ukunciphisa ukusetyenziswa kwe-LED akukona nje ukuba nefuthe elihle ekulawuleni iindleko, kodwa sibona nezinye iziphumo ezilungileyo kwiimodyuli.Umzekelo, ubushushu bemodyuli buya kuncitshiswa ngenxa yokusetyenziswa kancinci kwee-LED.Ukuba sithatha oku ngasentla kwe-32" LCDTV njengomzekelo, ukusetyenziswa kancinci kwenani le-LED kunokunciphisa ubushushu bemodyuli malunga ne-10% -15%. Ii-TV, ukusuka Ngokubanzi, ukucutha ubushushu kufuneka kube nefuthe elihle kubomi bamalungu e-elektroniki.Olu ncedo lubonakala ngakumbi kwindawo enkulu ye-LED backlight TV, kuba kukho ii-LED ezimbalwa ezingafane zisetyenziswe.

I-engile yokujonga ebanzi

Ukongeza, ukusetyenziswa kwezisombululo zefilimu zokuphucula ukuqaqamba komgangatho ophezulu nako kudlala indima entle kwi-engile yokubukela umabonwakude.Kuba umgaqo wobugcisa wefilimu yokuphucula ukuqaqamba komgangatho ophezulu kukuhambisa isibane sepolarized kwimodyuli yesibane esingasemva ukuze sijikeleze kwaye sibonakalise de ingene kwiglasi.Imodyuli yokukhanya kwangasemva esebenzisa ifilimu yokuphucula ukuqaqamba iphucula ukuqaqamba malunga ne-30% xa kuthelekiswa nemodyuli engasebenzisi ifilim yokubona.Kuba ifilimu yokuphucula ukuqaqamba okukumgangatho ophezulu yahlukile kwifilim yeprism ngokubanzi, akufuneki ukuba incame i-engile yokujonga ukwandisa ukuqaqamba, ngoko ke ifilimu yokuphucula ukuqaqamba okukumgangatho ophezulu ithandwa kakhulu ngabavelisi beTV basekhaya nabangaphandle.Ngommandla okhulayo weLCDTVs, abathengi sele beqalisile ukuba neemfuneko ezithile zokujonga ii-angles.I-47" LCD TV ene-intshi ezingaphezulu kwe-10,000 ibekwe embindini wegumbi lokuhlala. Ewe, intloko yekhaya inethemba lokuba iindwendwe ezihleli nakweyiphi na i-engile zingakonwabela umgangatho ofanayo wesikrini sikamabonakude.

Ukonga umbane kunye nokonga amandla

Ngokuqinisekileyo, uluntu lunokufumana ngokuthe ngqo izibonelelo zokukhanya kwe-LED backlights, oko kukunciphisa ukusetyenziswa kwamandla ngokubanzi kweTV.I-32 yesiqhelo ye-TV ye-backlight ye-LED, inqanaba langoku lidla ngokubanzi malunga ne-80W. Eli nqanaba lilingana nenqanaba lesithathu kwimigangatho yamva nje yokusebenza kwamandla kazwelonke.

Ukuba abavelisi bafuna ukuphucula imigangatho yokusetyenziswa kwamandla eTV, kukho izisombululo ezininzi ezihambelanayo, kodwa ukusebenzisa ifilimu yokuphucula ukukhanya okuphezulu kufuneka kube yeyona ndlela ilula kwaye ithe ngqo kwaye isebenzayo yokuphucula ukusebenza kokusetyenziswa kwamandla.Ukuba kudityaniswe nefilimu yokuphucula ukukhanya okuphezulu, ukusetyenziswa kwamandla kungancitshiswa malunga ne-20% -30% ngelixa kugcinwa izinga elifanayo lokukhanya (ukusebenza kokugqibela kuxhomekeke kwiteknoloji yophawu ngalunye).Ukusuka kubalo lwamanani, ukusetyenziswa kwamandla e-TV kunokuphuculwa ukusuka kwi-80W ukuya malunga ne-60W ngefilimu yokuphucula ukukhanya okukumgangatho ophezulu.Ukuphuculwa kokusetyenziswa kwamandla akuvumeli kuphela abavelisi ukuba basebenzisane ngamandla nomgaqo-nkqubo kazwelonke wokukhusela indalo, kodwa kunceda abathengi abaneebhilikhwe zombane ezinxulumene nazo.

Ukusuka kolu hlalutyo lobugcisa lungasentla, siyabona ukuba uyilo olukhanyisa umva oluluphele lunenzuzo enkulu kubavelisi nakubathengi.Kwixesha elizayo elingekude, ii-LED ezinecala elinye ezikhanyiswe ecaleni kufuneka zibe yeyona ndawo igqibeleleyo yezibane ze-LED.
