I-FAQ ye-LED Basics

Yini isibonisi se-LED?

Ngendlela elula kakhulu, i-LED Display iyiphaneli eyisicaba eyenziwe ngama-LED diode amancane abomvu, aluhlaza okwesibhakabhaka nokuluhlaza okwesibhakabhaka ukuze amele ngokubonakalayo isithombe sevidiyo yedijithali.

Izibonisi ze-LED zisetshenziswa emhlabeni wonke ngezindlela ezahlukahlukene, njengamabhodi ezikhangiso, emakhonsathini, ezikhumulweni zezindiza, ukuthola indlela, indlu yokukhulekela, izimpawu zokudayisa, nokunye okuningi.

Isibonisi se-LED sihlala isikhathi esingakanani?

Uma kuqhathaniswa nempilo yesikrini se-LCD emahoreni angu-40-50,000, isibonisi se-LED senziwa ukuthi sithathe amahora angu-100,000 - okuphinda kabili impilo yesikrini.

Lokhu kungahluka kancane kusukela ekusetshenzisweni nokuthi isibonisi sakho sigcinwa kahle kangakanani.

Ngikuthumela kanjani okuqukethwe kusibonisi?

Uma kuziwa ekulawuleni okuqukethwe kusibonisi sakho se-LED, akuhlukile ngempela kune-TV yakho.

Usebenzisa isilawuli sokuthumela, esixhunywe okokufaka okuhlukahlukene njenge-HDMI, i-DVI, njll., futhi uxhume noma iyiphi idivayisi ofuna ukuyisebenzisa ukuze uthumele okuqukethwe ngesilawuli.

Lokhu kungaba induku ye-Amazon Fire, i-iPhone yakho, ikhompuyutha ephathekayo yakho ephathekayo, noma i-USB.

Kulula ngendlela emangalisayo ukuyisebenzisa nokusebenza, njengoba kuwubuchwepheshe osuvele ubusebenzisa nsuku zonke.

Yini eyenza iselula yesibonisi se-LED iqhathaniswa nesaphakade?

Kubalulekile ukwazi uma ufaka unomphela, lapho ungeke uhambise noma uqaqe isibonisi sakho se-LED.

Iphaneli ye-LED engunaphakade izoba nendawo engemuva evalekile, kuyilapho isibonisi seselula sihluke kakhulu.

Isibonisi seselula sinekhabethe elivuleke kakhudlwana elinezintambo eziveziwe kanye nezinsimbi.

Lokhu kuvumela ikhono lokufinyelela ngokushesha nokushintsha amaphaneli, kanye nokusetha okulula nokudiliza.

Ukwengeza, iphaneli yesibonisi enamaselula inezici ezinjengezindlela zokukhiya ezisheshayo nezibambo ezihlanganisiwe zokuphatha.

Imibuzo Ebuzwa Njalo Ubuchwepheshe Besikrini Se-LED

Kuyini ukuphakama kwephikseli?

Ngokuphathelene nobuchwepheshe be-LED, i-pixel iyi-LED ngayinye.

Iphikseli ngayinye inenombolo ehlotshaniswa nebanga elithile phakathi kwe-LED ngayinye ngamamilimitha — lokhu kubizwa ngokuthi ukuphakama kwephikseli.

Ephansi i-umbala we-pixelInombolo iwukuthi, uma ama-LED eseduze esikrinini, okwenza ukuminyana kwephikseli ephezulu nokulungiswa kwesikrini okungcono.

Lapho ukuphakama kwephikseli ephezulu, ama-LED eba kude kakhulu, ngakho-ke kunciphisa ukulungiswa.

Ukuphakama kwe-Pixel yesibonisi se-LED kunqunywa ngokusekelwe endaweni, ngaphakathi/ngaphandle, nebanga lokubuka.

Ayini ama-nits?

I-nit iyunithi yokulinganisa yokunquma ukukhanya kwesikrini, i-TV, ikhompuyutha ephathekayo, nokunye okufanayo.Empeleni, uma inani lama-nits lilikhulu, isibonisi siyakhanya.

Isilinganiso senani lamanithi esibonisi se-LED siyahlukahluka — ama-LED angaphakathi angama-1000 nits noma agqamile, kanti i-LED yangaphandle iqala ku-4-5000 nits noma ngokugqamile ukuze iqhudelane nokukhanya kwelanga okuqondile.

Ngokomlando, ama-TV abe nenhlanhla yokuba nama-nits angama-500 ngaphambi kokuthi ubuchwepheshe buvele - futhi ngokuphathelene namaphrojekhtha, akalwa ngamalumens.

Kulokhu, ama-lumens awakhanyi njengama-nits, ngakho-ke izibonisi ze-LED zikhipha isithombe sekhwalithi ephezulu kakhulu.

Okuthile ongacabanga ngakho lapho unquma ngokulungiswa kwesikrini sakho ngokucabangela ukukhanya, ukwehlisa ukulungiswa kwesibonisi sakho se-LED, ungasithola ngokugqama.

Lokhu kungenxa yokuthi njengoba ama-diode ehlukana kakhulu, okushiya indawo yokusebenzisa i-diode enkulu engakhuphula ama-nits (noma ukukhanya).

Isho ukuthini i-common cathode?

I-cathode evamile iyisici sobuchwepheshe be-LED okuyindlela ephumelela kakhudlwana yokuletha amandla kuma-diode e-LED.

I-cathode evamile inika amandla okulawula i-voltage kumbala ngamunye we-LED diode (Okubomvu, Okuluhlaza Okuhlaza Okuluhlaza) ngawodwana ukuze ukwazi ukudala isibonisi esizonga amandla kakhudlwana, futhi futhi ukhiphe ukushisa ngokulinganayo.

Siphinde sikubizeIsibonisi se-LED esonga amandla

Yini i-flip-chip?

Ukusebenzisa ubuchwepheshe be-flip-chip kuyindlela ethembeke kakhulu yokuhlanganisa i-chip ebhodini.

Yehlisa ukuncishiswa kokushisa kakhulu futhi, yona, i-LED iyakwazi ukukhiqiza isibonisi esikhanyayo nesiwonga kakhudlwana.

Nge-flip-chip, ususa ukuxhumana okuvamile kwentambo futhi uhamba nendlela yokubopha okungenantambo, okunciphisa amathuba okuhluleka kakhulu.

Yini i-SMD?

I-SMD imele i-Surface Mounted Diode - uhlobo olusetshenziswa kakhulu lwe-LED diode namuhla.

I-SMD iwukuthuthuka kobuchwepheshe uma iqhathaniswa nama-Standard LED diode ngomqondo wokuthi ibekwe isicaba ngokuqondile ngokumelene nebhodi lesekethe.

Ama-LED ajwayelekile, ngakolunye uhlangothi, adinga izintambo zocingo ukuze zibambe endaweni ebhodini lesifunda.

Iyini i-COB?

I-COBisifinyezo seI-Chip Ebhodini.

Lolu uhlobo lwe-LED olwakhiwe ngokubopha ama-chips amaningi e-LED ukuze kwakhe imojuli eyodwa.

Izinzuzo kubuchwepheshe be-COB isibonisi esikhanyayo esinezingxenye ezimbalwa okufanele ubhekane nazo ezindlini, esiza ukwehlisa ukushisa okukhiqizwayo nokudala isibonisi esizonga amandla amaningi sisonke.

Ngidinga ukulungiswa okuphezulu kangakanani?

Uma kuziwa ekulungisweni kwesibonisi sakho se-LED, kubalulekile ukucabangela izici ezimbalwa: usayizi, ibanga lokubuka, nokuqukethwe.

Ngaphandle kokuqaphela, ungakwazi ukweqa kalula ukulungiswa okungu-4k noma okungu-8k, okungenangqondo ekuletheni (kanye nasekutholeni) okuqukethwe kulelo zinga lekhwalithi ukuze uqale.

Awufuni ukweqa ukulungiswa okuthile, ngoba ngeke ube nokuqukethwe noma amaseva okukushayela.

Ngakho-ke, uma isibonisi sakho se-LED sibukwa eduze, uzofuna ukuphakama kwephikseli ephansi ukuze ukhiphe ukucaca okuphezulu.

Kodwa-ke, uma isibonisi sakho se-LED sisikali esikhulu kakhulu futhi singabukelwa eduze, ungabalekela ukuphakama kwephikseli ephakeme kakhulu nokulungiswa okuphansi futhi ube nesibonisi esihle kakhulu.

Ngazi kanjani ukuthi iyiphi iphaneli ye-LED engilungele?

Ukunquma ukuthi yiniIsixazululo sokubonisa i-LEDkungcono kuwe kuncike ezicini eziningana.

Udinga ukuzibuza kuqala - ingabe lokhu kuzofakwaendlininomangaphandle?

Lokhu, kusukela ku-bat, kuzonciphisa izinketho zakho.

Ukusuka lapho, udinga ukuthola ukuthi udonga lwakho lwevidiyo ye-LED luzoba lukhulu kangakanani, hlobo luni lokulungiswa, ukuthi kuzodingeka lube yiselula noma unomphela, nokuthi kufanele lufakwe kanjani.

Uma usuyiphendulile leyo mibuzo, uzokwazi ukuthola ukuthi iyiphi iphaneli ye-LED ehamba phambili.

Khumbula, siyazi ukuthi usayizi owodwa awulingani konke - yingakho sinikezaizixazululo ngokwezifisokanjalo.

Ngisigcina kanjani isikrini sami se-LED (noma ngisilungise)?

Impendulo yalokhu incike ngokuphelele ekutheni ubani ofake ngokuqondile isibonisi sakho se-LED.

Uma usebenzise uzakwethu wokuhlanganiswa, uzofuna ukuxhumana naye ngokuqondile ukuze uthole ukulungiswa noma ukulungiswa.

Nokho, uma usebenze ngqo neYonwaytech LED,ungasishayela ucingo.

Okuqhubekayo, isibonisi sakho se-LED sizodinga ukulungiswa okuncane kakhulu, ngaphandle kokusula ngezikhathi ezithile uma isikrini sakho singaphandle ezintweni.

Kuthatha isikhathi esingakanani ukufaka?

Lesi isimo esiwuketshezi kakhulu, kuye ngosayizi wesikrini, indawo, noma ngabe singaphakathi noma ngaphandle, nokuningi.

Ukufakwa okuningi kuqedwa ezinsukwini ezingu-2-5, nokho uhlelo ngalunye luhlukile futhi uzothola umugqa wesikhathi wangempela wesibonisi sakho se-LED.

Iyini iwaranti yemikhiqizo yakho ye-LED?

Isici esibalulekile okufanele sicatshangelwe iwaranti yesikrini se-LED.

Ungafundaiwaranti yethu lapha.

Ngaphandle kwewaranti, lapha e-Yonwaytech LED, lapho uthenga udonga olusha lwevidiyo ye-LED kithi, sikhiqiza futhi sinikeze izingxenye ezengeziwe ukuze ukwazi ukunakekela nokulungisa isikrini sakho iminyaka engu-5-8 ngaphezulu.

Iwaranti ilingana nekhono lakho lokukhanda/ukushintsha izingxenye, yingakho sikhiqiza okwengeziwe ukuze siqinisekise ukuthi uyakhava iminyaka eminingi ezayo.
