Umntu oqhelekileyo angahlula njani umgangatho wesiboniso se-LED?Ngokubanzi, kunzima ukukholisa umsebenzisi ngokusekelwe ekuziphenduleleni komthengisi.Kukho iindlela ezininzi ezilula zokuchonga umgangatho wombala ogcweleyo wesikrini se-LED.
1. Ukucaba
Umphezulu othe tyaba wesikrini se-LED kufuneka ube ngaphakathi ± 0.1mm ukuqinisekisa ukuba umfanekiso obonisiweyo awugqwethwanga.Iiprotrusions ezingaphelelanga okanye ukuphumla kuya kukhokelela kwi-engile efileyo kwi-engile yokujonga yesikrini se-LED.Phakathi kwekhabhinethi ye-LED kunye nekhabhinethi ye-LED, isithuba phakathi kwemodyuli kunye nemodyuli kufuneka ibe ngaphakathi kwe-0.1mm.Ukuba i-gap inkulu kakhulu, umda wesikrini sokubonisa i-LED uya kubonakala kwaye umbono awuyi kulungelelaniswa.Umgangatho we-flatness umiselwa ikakhulu yinkqubo yemveliso.
2. Ukuqaqamba
Ukukhanya kweIsikrini se-LED sangaphakathikufuneka ibe ngaphezulu kwe 800cd/m2, kunye nokuqaqamba kweumboniso we-LED wangaphandlekufuneka ibe ngaphezu kwe-5000cd/m2 ukuqinisekisa isiphumo esibonakalayo sesikrini se-LED, ngaphandle koko umfanekiso obonisiweyo awuyi kucaca ngenxa yokuba ukukhanya kuphantsi kakhulu.Ukukhanya kwesikrini sokubonisa i-LED akukhanyi kangangoko kunokwenzeka, kufuneka kuhambelane nokukhanya kwephakheji ye-LED.Ukwandisa ngokungaboniyo kwangoku ukwandisa ukukhanya kuya kubangela ukuba i-LED iyancipha ngokukhawuleza, kwaye ubomi bomboniso we-LED buya kuncipha ngokukhawuleza.Ukukhanya kwesiboniso se-LED kunqunywe ngokukodwa ngumgangatho wesibane se-LED.
3. I-engile yokujonga
I-angle yokujonga ibhekisa kwi-engile ephezulu apho unokubona yonke imixholo yesikrini se-LED ukusuka kwiscreen sevidiyo se-LED.Ubungakanani be-engile yokujonga ichaza ngokuthe ngqo abaphulaphuli besikrini se-LED, ngoko ke inkulu ngcono, i-angle yokujonga kufuneka ibe ngaphezu kwe-150 degrees.Ubungakanani be-angle yokujonga ubukhulu becala bunqunywe yindlela yokupakisha yezibane ze-LED.
4. Ibhalansi emhlophe
Impembelelo yokulinganisela emhlophe yenye yezona zibonakaliso ezibalulekileyo zokubonisa i-LED.Ngokuphathelele umbala, umhlophe ococekileyo uya kuboniswa xa umlinganiselo wemibala emithathu ephambili ebomvu, eluhlaza kunye neblue yi-1: 4.6: 0.16.Ukuba kukho ukutenxa okuncinci kumlinganiselo wangempela, kuya kubakho ukutenxa kwibhalansi emhlophe.Ngokuqhelekileyo, kuyimfuneko ukunikela ingqalelo ukuba umhlophe okwesibhakabhaka okanye ophuzi.into eluhlaza.Kwi-monochrome, umncinci umehluko ekukhanyeni kunye nobude be-wavelength phakathi kwee-LED, ngcono.Akukho mahluko wombala okanye umbala owenziweyo xa umi kwicala lesikrini, kwaye ukuhambelana kungcono.Umgangatho webhalansi emhlophe ubukhulu becala ugqitywe ngumlinganiselo wokukhanya kunye nobude bokukhanya kwesibane se-LED kunye nenkqubo yokulawula isikrini sokubonisa i-LED.
5. Ukunciphisa umbala
Ukunciphisa umbala kubhekiselele kumbala oboniswe kwisiboniso se-LED kufuneka uhambelane kakhulu nombala womthombo wokudlala, ukuze uqinisekise ubunyani bomfanekiso.
6. Nokuba kukho i-mosaic kunye ne-dead spot phenomenon
I-Mosaic ibhekisela kwizikwere ezincinci ezihlala zikhanya okanye zihlala zimnyama kwisibonisi se-LED, into eyenzekayo ye-module necrosis.Isizathu esona sizathu kukuba umgangatho we-IC okanye izibane zesibane ezisetyenziswe kwisiboniso se-LED akulungile.Indawo efileyo ibhekisa kwindawo enye ehlala iqaqambile okanye ihlala imnyama kwisibonisi se-LED.Inani lamanqaku afileyo lichongwa ngokukodwa ngumgangatho wokufa kunye nokuba imilinganiselo yokuchasana nomenzi ilungile.
7. Ngombala okanye ngaphandle kweebhloko zemibala
Ibhloko yombala ibhekisa kumahluko ocacileyo wombala phakathi kweemodyuli ezikufutshane.Ukutshintshwa kombala kusekelwe kwimodyuli.Isiganeko sebhlokhi yombala sibangelwa ikakhulu yinkqubo yokulawula engalunganga, inqanaba eliphantsi legrey kunye ne-low scanning frequency.
8. Bonisa uzinzo
Ukuzinza kubhekisela kumgangatho othembekileyo wesiboniso se-LED kwisinyathelo sokuguga emva kokugqiba.
9. Ukhuseleko
Umboniso we-LED uqulunqwe ngeekhabhinethi ezininzi ze-LED, ikhabhinethi nganye ye-LED kufuneka ibekwe phantsi, kwaye ukuchasana komhlaba kufuneka kube ngaphantsi kwe-0.1 ohms.Kwaye inokumelana nombane ophezulu, i-1500V 1min ngaphandle kokuphuka.Iimpawu zesilumkiso kunye nezilogeni ziyafuneka kwi-terminal ye-high-voltage input kunye ne-high-voltage wiring yonikezelo lwamandla.
10. Ukupakisha kunye nokuThumela
Isikrini sokubonisa i-LED siyimpahla exabisekileyo enobunzima obukhulu, kwaye indlela yokupakisha esetyenziswa ngumenzi ibaluleke kakhulu.Ngokuqhelekileyo, ifakwe kwikhabhinethi ye-LED enye, kwaye indawo nganye yekhabhinethi ye-LED kufuneka ibe nezinto ezikhuselayo kwi-buffer, ukwenzela ukuba i-LED inendawo encinci yemisebenzi yangaphakathi ngexesha lokuthutha.
