Ukukhanya kwangasemva kwescreen se-LCD esikhulu kunye nokukhanya ngokubanzi kuvuselela ukukhula okukhawulezileyo

Kwi-2015 kunye ne-2016, ingeniso yoshishino lokukhanyisa i-slid-state iye yagcina izinga lokukhula elilinganayo ledijithi enye, kodwa ngo-2017 imboni kulindeleke ukuba ikhuthaze izinga lokukhula kwengeniso ye-LED ukufikelela kwidijithi ephindwe kabini.

I-iSuppli iqikelela ukuba i-turnover yemakethe ye-LED ngo-2017 iya kukhula malunga ne-13.7%, kwaye izinga lokukhula ngonyaka ka-2016-2012 liya kuba malunga ne-14.6%, kwaye liya kufikelela kwi-12.3 yeebhiliyoni zeedola zaseMelika ngo-2012. Ngo-2015 kunye no-2016, i Inguqu kwimarike ye-LED yehlabathi inyuke kuphela nge-2.1% kunye ne-8.7% ngokulandelelanayo.

La manani abandakanya zonke izixhobo zokunyuka kwendawo (SMD) kunye nezibane ze-LED eziphuma kumngxuma kunye ne-alphanumeric display LEDs-kubandakanywa nokukhanya okusemgangathweni, ukukhanya okuphezulu (HB) kunye nokukhanya okuphezulu okuphezulu (UHB) ii-LED.

Inxalenye enkulu yokukhula okulindelekileyo okukhankanywe ngasentla iya kuvela ekukhanyeni okuphezulu okuphezulu kunye nokukhanya okuphezulu kwee-LED ezisetyenziselwa ukukhanyisa izicelo.Ngo-2012, ii-LED eziqaqambe kakhulu ziya kwenza malunga ne-31% yembuyekezo ye-LED iyonke, ngaphezulu kwe-4% ngo-2015.

Umqhubi ophambili wokukhula kweemarike

“Kwinqanaba elitsha lokukhula kwe-LED, imakethi iyaqhubeka nokuba nemfuno eqinileyo yokukhanya okuqinileyo kwizibane zasemva kunye nokuboniswa kwesixhobo esiphathwayo.Le yeyona nto iphambili ekhuthaza ukukhula kweemarike ze-LED, "utshilo uDkt. Jagdish Rebello, umlawuli kunye nomhlalutyi oyintloko we-iSuppli.“Izibane zemoto ngaphakathi, kunye nokukhanya ngasemva kweeLCD ezinkulu zeTV kunye neelaptops, ezi marike zivelayo ziyakukhuthaza ukukhula koshishino lweLED.Ukongeza, uphuhliso oluqhubekayo lwetekhnoloji yokukhanya kobume obuqinileyo kuya kwenza ukuba ii-LED zifumane izicelo ezitsha kwizibane zokuhombisa kunye neemarike zokukhanyisa izakhiwo.Indawo yekarati.”

Ukukhanya kwasemva kwe-LCD kusesona sicelo siphambili se-LED

Kutshanje, imiboniso ye-LCD yesikrini esincinci kunye nezibane zeqhosha lefowuni eziphathwayo ziseyeyona ntengiso inkulu yesicelo kwii-LEDs.Kwi-2017, ezi zicelo ziya kuphendula ngaphezu kwe-25% ye-turnover ye-market ye-LED.

I-LED ijolise kwizibane ezinkulu ze-LCD

Ukuqala ngo-2017, ukukhanya ngasemva kweeLCD ezinkulu ezifana neencwadi kunye ne-intuitive LCD TVs iba lusetyenziso olulandelayo olubalulekileyo lwee-LED.

Iindleko ze-LCD backlight module (BLU) zisephezulu kakhulu kunezo zendabuko ze-CCFL BLU, kodwa iindleko zezi zimbini zisondela ngokukhawuleza.Kwaye i-LED BLU ineenzuzo zokusebenza, ezifana nokuchasana okuphezulu, ixesha lokuvula ngokukhawuleza, i-gamut yombala obanzi, kunye nokungabikho kwe-mercury kunceda ukuba yamkelwe kwi-LCDs.

Abanye ababoneleli be-LED, abavelisi be-BLU, abavelisi beepaneli ze-LCD kunye nabavelisi be-TV / ukubonisa abavelisi be-OEM ngoku sele beqalisile ukusebenzisa ii-LED njenge-backlight ye-LCDs zesikrini esikhulu.Izikrini ezinkulu zeLCD ezisebenzisa i-LED BLU nazo ziqalisile ukuthunyelwa kwezorhwebo.

I-LED: Ikamva lokukhanyisa ngokubanzi

Ukuphuhliswa kwee-LED eziguquguqukayo eziphezulu kunye nokusebenza okukhanyayo okungaphezulu kwe-100 lumens / watt kunye nokuvela koyilo olutsha luye lwavumela ii-LEDs ukuba zisebenze ngokutshintshana ngoku ngaphandle kwesidingo se-inverters, ngaloo ndlela zityhala ii-LED kufutshane nemarike yokukhanyisa ngokubanzi.

Ii-LED zisetyenziswe kwiindidi ezahlukeneyo zokukhanyisa ngaphakathi nangaphandle, kwaye ziqala ukugxila kwizicelo zokukhanyisa ngokubanzi ezifana nezibane, izibane zegadi, kunye nezibane zesitrato.Olu setyenziso luvula iimarike zokukhanyisa kwe-LED kwintsimi yokukhanya kwekhaya kunye nenkampani.

Ukongezelela, ihlabathi liye lanyusa umthetho wokuthintela ukusetyenziswa kwezibane ze-incandescent kunye nokukhuthaza ukusetyenziswa kwemithombo yokukhanya egcina amandla.Kwixesha elizayo elingekude, iityhubhu ze-compact fluorescent (CFL) ziya kuzuza kwizenzo zomthetho ezivimbela ukusetyenziswa kwezibane ze-incandescent.

Kodwa kwixesha elide, izibonelelo zokukhanya kwe-slid-state ziya kugqithisa umahluko weendleko phakathi kwee-LED kunye neeCFL.Kwaye njengoko ukusebenza kwe-LED kuqhubeka nokuphucula, umahluko weendleko uya kuncitshiswa ngakumbi.

I-iSuppli iqikelela ukuba ngo-2020 ii-bulbs ze-LED ziya kuqala ukusetyenziswa ekukhanyeni ngokubanzi kwindawo yokuhlala kunye nezibane zenkampani.
