Umuntu ovamile angayihlukanisa kanjani ikhwalithi yesibonisi se-LED?Ngokuvamile, kunzima ukukholisa umsebenzisi ngokusekelwe ekuziphenduleleni komthengisi.Kunezindlela ezimbalwa ezilula zokukhomba ikhwalithi yesikrini esigcwele sombala we-LED.
1. Ukucaba
Ukucaba kwendawo yesikrini esibonisiwe se-LED kufanele kube phakathi kuka-±0.1mm ukuze kuqinisekiswe ukuthi isithombe esibonisiwe asihlanekezelwa.Ama-protrusions ayingxenye noma ama-recesses azoholela ku-engeli efile ku-engeli yokubuka yesikrini sesibonisi se-LED.Phakathi kwekhabhinethi ye-LED nekhabethe le-LED, igebe phakathi kwemojula nemojula kufanele libe ngaphakathi kuka-0.1mm.Uma igebe likhulu kakhulu, umngcele wesikrini sokubonisa se-LED uzoba sobala futhi umbono ngeke uhlanganiswe.Izinga le-flatness linqunywa ikakhulukazi inqubo yokukhiqiza.
2. Ukukhanya
Ukukhanya kweisikrini se-LED sangaphakathikufanele ibe ngaphezu kuka-800cd/m2, nokukhanya kweisibonisi se-LED sangaphandlekufanele ibe ngaphezu kuka-5000cd/m2 ukuze kuqinisekiswe umphumela obonakalayo wesikrini se-LED, ngaphandle kwalokho isithombe esibonisiwe sizobe singacacile ngoba ukukhanya kuphansi kakhulu.Ukukhanya kwesikrini se-LED akukhanyi ngangokunokwenzeka, kufanele kufane nokukhanya kwephakheji ye-LED.Ukwandisa ngokungaboni ukuze kwandiswe ukukhanya kuzobangela i-LED yehle ngokushesha kakhulu, nempilo yesibonisi se-LED izokwehla ngokushesha.Ukukhanya kwesibonisi se-LED kunqunywa ikakhulukazi ikhwalithi yesibani se-LED.
3. I-engeli yokubuka
I-engeli yokubuka isho i-engeli ephezulu lapho ungabona khona konke okuqukethwe kwesikrini se-LED kusuka kusikrini sevidiyo ye-LED.Usayizi we-engeli yokubuka unquma ngokuqondile izethameli zesikrini sokubonisa se-LED, ngakho-ke uma sikhulu siba ngcono, i-engeli yokubuka kufanele ibe ngaphezu kwamadigri angu-150.Ubukhulu be-angle yokubuka ikakhulukazi kunqunywa indlela yokupakisha yezibani ze-LED.
4. Ibhalansi emhlophe
Umphumela webhalansi omhlophe ungenye yezinkomba ezibaluleke kakhulu zesibonisi se-LED.Mayelana nombala, okumhlophe okumsulwa kuzoboniswa uma isilinganiso semibala emithathu eyinhloko ebomvu, eluhlaza okwesibhakabhaka nokuluhlaza okwesibhakabhaka singu-1:4.6:0.16.Uma kukhona ukuchezuka okuncane esilinganisweni sangempela, kuzoba nokuchezuka kwebhalansi emhlophe.Ngokuvamile, kuyadingeka ukunaka ukuthi umhlophe okwesibhakabhaka noma ophuzi.into eluhlaza.Nge-monochrome, umehluko wokukhanya nobude beza phakathi kwama-LED uba mncane, uba ngcono.Awukho umehluko wombala noma ukufakwa kombala uma umi eceleni kwesikrini, futhi ukuvumelana kungcono.Ikhwalithi yebhalansi emhlophe inqunywa ngokuyinhloko isilinganiso sokukhanya nobude begagasi besibani se-LED kanye nesistimu yokulawula yesikrini sokubonisa se-LED.
5. Ukuncipha kombala
Ukwehliswa kombala kubhekisela kumbala ovezwe kusibonisi se-LED kufanele uhambisane kakhulu nombala womthombo wokudlala, ukuze kuqinisekiswe ubuqiniso besithombe.
6. Ukuthi kukhona i-mosaic ne-dead spot phenomenon
I-Mosaic ibhekisela ezikweleni ezincane ezihlala zikhanya noma ezihlale zimnyama kusibonisi se-LED, okuyisenzakalo se-module necrosis.Isizathu esiyinhloko ukuthi ikhwalithi ye-IC noma ubuhlalu besibani obusetshenziswe kusibonisi se-LED ayilungile.Iphoyinti elifile libhekisela endaweni eyodwa ehlala ikhanya noma ehlala imnyama kusibonisi se-LED.Inani lamaphoyinti afile linqunywa ikakhulukazi ikhwalithi yefa nokuthi izinyathelo zomkhiqizi zokulwa ne-static ziphelele yini.
7. Ngamabhlogo ombala noma ngaphandle kwawo
Ibhulokhi yombala ibhekisela kumehluko osobala wombala phakathi kwamamojula aseduze.Ukushintsha kombala kusekelwe kumojuli.Isici sokuvimba umbala sibangelwa ikakhulukazi uhlelo lokulawula olungalungile, izinga eliphansi elimpunga kanye nemvamisa ephansi yokuskena.
8. Bonisa ukuzinza
Ukuzinza kubhekisela kwikhwalithi ethembekile yesibonisi se-LED esinyathelweni sokuguga ngemva kokuqedwa.
9. Ezokuphepha
Isibonisi se-LED sakhiwe ngamakhabethe e-LED amaningi, ikhabethe ngalinye le-LED kufanele libe phansi, futhi ukumelana nokubekwa phansi kufanele kube ngaphansi kuka-0.1 ohms.Futhi ingamelana ne-voltage ephezulu, i-1500V 1min ngaphandle kokuqhekeka.Kudingeka izimpawu eziyisixwayiso neziqubulo kutheminali yokufaka i-voltage ephezulu kanye nezintambo ezinamandla kagesi.
10. Ukupakisha nokuthumela
Isikrini sokubonisa se-LED siyimpahla ebalulekile enesisindo esikhulu, futhi indlela yokupakisha esetshenziswa umenzi ibaluleke kakhulu.Ngokuvamile, ihlanganiswe ekhabetheni elilodwa le-LED, futhi indawo ngayinye yekhabhinethi ye-LED kufanele ibe nezinto zokuzivikela ukuze i-buffer, ukuze i-LED ibe nesikhala esincane semisebenzi yangaphakathi ngesikhathi sokuthutha.
