Izinto ezininzi ezintle zokwahlula umgangatho wesiboniso se-LED

Kwi-"foreman" indlela yokuchonga umgangatho wesiboniso se-LED, akayiqondi ngokupheleleyo isiboniso se-LED. Phantsi kweemeko eziqhelekileyo, kunzima ukwenza umsebenzisi aqiniseke, kwaye iintsuku ezilandelayo zizo zonke iintlobo zokunyaniseka. Umboniso ulungile kwaye umgangatho ulungile, ndiyathemba ukukunceda xa uthenga umboniso ogcwele umbala.

Umboniso ulungile kwaye umgangatho ulungile, ndiyathemba ukukunceda xa uthenga umboniso ogcwele umbala.

1.Umgangatho wesiboniso se-LED usayinwe ikakhulu kule miba ilandelayo: Ukuthe tyaba Umphezulu othe tyaba wesiboniso ungaphakathi ± 1 mm ukuqinisekisa ukuba umfanekiso oboniswayo awuwuphambanisi umfanekiso, uqikelelo lwendawo okanye uphumlo lubangela i-angle efileyo ngaphakathi. i-engile ebonakalayo yomboniso. Phakathi kwebhokisi kunye nekhabhinethi, isithuba phakathi kwemodyuli kunye nemodyuli ingaphakathi kwe-1 mm. I-gap inkulu kakhulu, ibangela ukuba umda wokubonisa ubonakale, imbonakalo ayilungelelaniswa. Umgangatho we-flatness umiselwa ikakhulu yinkqubo yemveliso.

2. Ukukhanya kunye ne-angle ebonakalayo Ukukhanya kwesikrini sombala ogcweleyo wangaphakathi kungaphezulu kwe-800 cd / m2, kunye nokukhanya kwesikrini esigcweleyo sangaphandle singaphezulu kwe-5000 cd / m2 ukuqinisekisa ukusebenza okuqhelekileyo kwesiboniso, ngaphandle koko umfanekiso obonisiweyo ayicacanga kuba ukukhanya kuphantsi kakhulu. Ukukhanya kwesiboniso akukhanyisi, kungcono, kufuneka kuhambelane nokukhanya kwephakheji ye-LED. Incasa enye yonyusa ukuqaqamba kwangoku, okuya kubangela ukuba ubuhle be-LED bukhawuleze kakhulu, kwaye ubomi bomboniso buyancipha ngokukhawuleza. Abathengisi banokufuneka ukuba banikeze iingxelo zeparameter ukuqinisekisa. Ubungakanani besikrini bumiselwa ikakhulu zizigqibo ezilungileyo nezingalunganga zokufa kwe-LED. I-engile ebonakalayo ibhekisa kowona mgangatho uphezulu onokuwubona ngawo wonke umxholo wesikrini kwiscreen. I-angle yokubonwayo imiselwe ngokuthe ngqo ngabaphulaphuli ababonisayo, ngoko ke inkulu ingcono. I-angle ebonakalayo ingaphezulu kwe-150 degrees. Ubungakanani be-angle ebonakalayo bunqunywe ngokukodwa yindlela yokupakishwa kwefa. Bangaphi abaqeshwayo "abasemzini" abachonga umgangatho wesiboniso se-LED

3. I-White balance effect Ibhalansi emhlophe yenye yezona zibonakaliso ezibalulekileyo zesiboniso. Umlinganiselo wombala ngu-1: 4.6: 0.16, uya kubonisa umhlophe ococekileyo, ukuba kukho ukutenxa okuncinci, kuya kubakho ukulungelelaniswa kwebhalansi emhlophe, ngokubanzi ingqalelo ukuba umhlophe uluhlaza okwesibhakabhaka, isiganeko esiluhlaza okwesibhakabhaka. Xa i-monochrome, umehluko wokukhanya phakathi kwee-LED kunye nokwahlukana kwe-wavelength kukuba, kungcono, ukuma kwicala lesikrini, akukho mahluko wombala okanye i-bias, ukuhambelana kuhle. Umgangatho webhalansi emhlophe umiselwa ikakhulu yinkqubo yolawulo ye-LED dolumin yokukhanya kwe-wavelength ratio kunye nesikrini sokubonisa, kwaye ukufa kukwachatshazelwa yipropati yokunciphisa umbala.

4. Ukunciphisa Umbala Ipropati yokunciphisa umbala ibhekisela ekunciphiseni ukubonakaliswa kombala, kwaye umbala womboniso wokubonisa uhambelana nombala womthombo wokudlala, ukwenzela ukuba ukuvakalelwa kwangempela komfanekiso kuqinisekiswe.

5. Ine-mosaic, indawo efileyo I-Mosaic ibhekisa kwibhloko eqhelekileyo okanye eqhelekileyo emnyama encinci yesikwere evela kumboniso. Isizathu esona sizathu sokuba kutheni i-IC okanye umgangatho wokudibanisa osetyenziswe kwisiboniso awukho. Indawo efileyo ibhekisela kwindawo enye ebonakala kwisiboniso, kwaye indawo efileyo inqunywe ngokukodwa ngumgangatho womgangatho wokuhla kunye nokuba imilinganiselo yokuchasana nomenzi iphelele.

6. Kukho ibhloko engenambala Ibhloko yombala ibhekiselele kumahluko ombala ocacileyo phakathi kwamaqela emowudi akufutshane. Ukutshintshwa kombala kwiiyunithi zeemodyuli. Isenzeko esibangelwa yibhlokhi yombala ikakhulu ihlwempuzekile, inqanaba lokunyuswa alikho phezulu, kwaye i-frequency yokuskena iphantsi.

7. Bonisa ukuzinza Ukuzinza kuthetha ukuba umboniso we-LED unokwethenjelwa kumgangatho wesigaba sokuguga emva kokwenza umkhiqizo ogqityiweyo. Kunokuvunyelwa umenzi ukuba aguge ukuze afumane imeko yemeko ngexesha lokuguga kwesikrini.

8. Ukhuseleko Isiboniso se-LED senziwe ngeebhokisi ezininzi. Icala ngalinye kufuneka libe ngukhuseleko lomhlaba, kwaye ukuchasana komhlaba kufuneka kube ngaphantsi kwe-0.1 Euro. Kwaye inokumelana noxinzelelo oluphezulu, i-1500V 1min ayibetheki. ISILUMKISO kunye nezilogeni kufuneka zilumkiswe kwigalelo lamandla ombane aphezulu kunye nonikezelo lwamandla kwiitheminali zamandla ombane aphezulu.

9. Ukupakishwa kunye nokuthutha Umboniso we-LED ungowezinto ezixabisekileyo, ubunzima bukhulu kakhulu, kwaye indlela yokupakisha esetyenziswa ngumenzi ibalulekile. Ngokubanzi, ngokwemeko enye, iikhabhini kufuneka zibe nendima ye-buffer ebhokisini, kwaye ibhokisi ayinkulu ngexesha lokuhamba. Ukupakishwa kwangaphandle kufuneka kube nokuchongwa okucacileyo.
