Isibonisi se-LED sakhiwe umugqa wama-diode akhipha ukukhanya, ngakho ikhwalithi ye-LED ithinta ngokuqondile ikhwalithi yesibonisi.
1. Ukukhanya kanye ne-angle yokubuka
Ukukhanya kwesikrini sokubonisa kuncike kakhulu ekuqineni kokukhanya kanye nokuminyana kwe-LED ye-LED.Eminyakeni yamuva, ubuchwepheshe obusha be-LED ku-substrate, i-epitaxy, i-chip kanye nephakheji buye bavela ngokungapheli, ikakhulukazi ukuzinza nokuvuthwa kobuchwepheshe bamanje bokunwebeka kanye nenqubo ye-indium tin oxide (ITO), eye yathuthukisa kakhulu ukukhanya okukhanyayo kwe-LED. .Njengamanje, ngaphansi kwesimo sokuthi i-engeli evundlile yokubuka ingamadigri angu-110 kanye ne-engeli eqondile yokubuka ngamadigri angu-50, ukuqina okukhanyayo kweshubhu eliluhlaza sekufinyelele ku-4000 mcd, ishubhu elibomvu selifinyelele ku-1500 mcd, futhi ishubhu eluhlaza okwesibhakabhaka isifinyelele ku-4000 mcd. ifinyelele ku-1000 mcd.Uma isikhala samaphikseli singu-20mm, ukukhanya kwesikrini sokubonisa kungafinyelela ngaphezu kuka-10,000nit.Isibonisi singasebenza ubusuku nemini kunoma iyiphi indawo
Uma ukhuluma ngombono wesikrini esibonisiwe, kunento okufanele ucabange ngayo: Izikrini zokubonisa ze-LED, ikakhulukazi izikrini zokubonisa zangaphandle, zibukwa ngokuyisisekelo kusukela phansi kuya phezulu, kuyilapho zisesimweni sezikrini ezikhona ze-LED, uhhafu wokukhanya okukhanyayo. liyanyamalala esibhakabhakeni esikhulu.
2. Ukufana nokucaca
Ngokuthuthukiswa kobuchwepheshe bokubonisa i-LED, ukufana sekuyinkomba ebaluleke kakhulu yokukala ikhwalithi yesibonisi.Kuvame ukuthiwa isibonisi se-LED "sicwebezela kukho konke futhi sicwebezela kuyo yonke isiqephu", okuyisingathekiso esicacile sokungalingani okukhulu phakathi kwamaphikseli namamojula.Amagama ochwepheshe athi "umphumela wothuli" kanye "nokwenzeka kwe-mosaic".
Izimbangela eziyinhloko zento engalingani yilezi: imingcele yokusebenza kwe-LED ayihambisani;Ukunemba komhlangano okunganele kwesikrini sokubonisa ngesikhathi sokukhiqiza nokufakwa;Amapharamitha kagesi wezinye izingxenye ze-elekthronikhi awahambisani ngokwanele;Ukwakhiwa kwamamojula nama-PCB akumisiwe.
Isizathu esiyinhloko "ukungahambisani kwemingcele yokusebenza kwe-LED".Ukungqubuzana kwalezi zinhlaka zokusebenza ikakhulukazi kufaka phakathi: ukushuba kokukhanya okungahambisani, i-eksisi ye-optical engahambisani, izixhumanisi zombala ezingahambisani, amajika okusabalalisa amandla okukhanya okungahambisani kombala ngamunye oyinhloko, nezici zokunciphisa ezingahambisani.
Indlela yokuxazulula ukungahambisani kwemingcele yokusebenza kwe-LED, kunezindlela ezimbili eziyinhloko zobuchwepheshe embonini njengamanje: okokuqala, ukuthuthukisa ukuhambisana kokusebenza kwe-LED ngokuqhubeka nokuhlukanisa imingcele yokucaciswa kwe-LED;Okunye ukuthuthukisa ukufana kwesikrini sokubonisa ngokulungisa okulandelayo.Ukulungiswa okwalandela nakho kuthuthukile kusukela ekulungisweni kwamamojula okuqala kanye nokulungiswa kwamamojula kuze kube iphuzu lanamuhla lokulungiswa kwephuzu.Ubuchwepheshe bokulungisa buthuthukile kusukela ekulungiseni ukukhanya kokukhanya kuya ekulungiseni ukuxhumanisa kombala wokukhanya.
Nokho, sikholelwa ukuthi ukulungiswa okulandelayo akunamandla onke.Phakathi kwazo, ukungqubuzana kwe-axis optical, ukungahambisani kwejika lokusabalalisa ukukhanya kokukhanya, ukungahambisani kwezimpawu zokunciphisa, ukunemba komhlangano ompofu kanye nomklamo ongajwayelekile akukwazi ukuqedwa ngokulungiswa okulandelayo, futhi ngisho nalokhu kulungiswa okulandelayo kuzokwandisa ukungahambisani kwe-axis optical. , ukuncishiswa nokunemba komhlangano.
Ngakho-ke, ngokuzijwayeza, isiphetho sethu siwukuthi ukulungiswa okulandelayo kuyikhambi kuphela, kuyilapho ukuhlukaniswa kwepharamitha ye-LED kuyimbangela kanye nekusasa eliyinhloko lemboni yokubonisa i-LED.
Ngokuqondene nobudlelwano phakathi kokufana kwesikrini nencazelo, kuvame ukuba nokungaqondi embonini, okungukuthi, isinqumo sithatha indawo yencazelo.Eqinisweni, incazelo yesikrini sokubonisa iwumuzwa wokuzicabangela weso lomuntu ekulungisweni, ukufana (isilinganiso sesignali-kuya-nomsindo), ukukhanya, ukugqama nezinye izici zesikrini sokubonisa.Ukunciphisa nje isikhala se-pixel esibonakalayo ukuze kuthuthukiswe ukulungiswa, kuyilapho uziba ukufana, ngokungangabazeki ukuthuthukisa ukucaca.Cabanga ngesikrini esibonisiwe "esinomphumela wothuli" kanye "nesenzakalo se-mosaic".Ngisho noma isikhala se-pixel esibonakalayo sincane futhi ukulungiswa kwayo kuphezulu, akunakwenzeka ukuthola incazelo yesithombe esihle.
Ngakho-ke, ngomqondo othile, "ukufana" kunokuthi "isikhala samaphikseli abonakalayo" okwamanje kukhawulela ukuthuthukiswa kwencazelo yesikrini sesibonisi se-LED.
3. I-pixel yesikrini sokubonisa ayilawuleki
Kunezizathu eziningi zokuthi amaphikseli esikrini esibonisiwe angalawuleki, okubaluleke kakhulu "ukuhluleka kwe-LED".
Izimbangela eziyinhloko zokuhluleka kwe-LED zingahlukaniswa zibe izici ezimbili: enye ikhwalithi empofu ye-LED ngokwayo;Okwesibili, indlela yokusebenzisa ayilungile.Ngokuhlaziya, siphetha ubudlelwano obuhambelanayo phakathi kwezindlela zokuhluleka kwe-LED kanye nezimbangela ezimbili eziyinhloko.
Njengoba kushiwo ngenhla, ukwehluleka okuningi kwe-LED akukwazi ukutholakala ekuhlolweni okujwayelekile nokuhlolwa kwe-LED.Ngaphezu kokukhishwa kwe-electrostatic discharge, umthamo omkhulu wamanje (obangela ukushisa okukhulu kwe-junction), amandla angaphandle nokunye ukusetshenziswa okungafanele, ukwehluleka okuningi kwe-LED kubangelwa ukucindezeleka okuhlukahlukene kwangaphakathi okubangelwa ama-coefficients ahlukene okunweba okushisayo kwama-chips e-LED, ama-epoxy resins, izisekelo, ngaphakathi. ukuhola, okuqinile kwe-crystal adhesives, izinkomishi ze-PPA nezinye izinto ezingaphansi kokushisa okuphezulu, izinga lokushisa eliphansi, izinguquko ezisheshayo zokushisa noma ezinye izimo ezinzima.Ngakho-ke, ukuhlolwa kwekhwalithi ye-LED kuwumsebenzi oyinkimbinkimbi kakhulu.
4. Impilo
Izici ezithinta impilo yesikrini sokubonisa se-LED zifaka phakathi izici zangaphakathi nezangaphandle, ezihlanganisa ukusebenza kwezingxenye ze-peripheral, ukusebenza kwamadivayisi akhipha ukukhanya kwe-LED, kanye nokumelana nokukhathala kwemikhiqizo;Izinto zangaphakathi zihlanganisa indawo yokusebenza yesikrini sokubonisa se-LED, njll.
