Izikrini zokubonisa ze-LED njengamanje zisetshenziselwa ukuboniswa kwesikrini okukhulu nangaphakathi, ngakho-ke kufanele sikhethe kanjani aIsikrini esiphakeme sokubonisa ukusebenza kwe-LED? Ubuhlalu be-LED yingxenye esemqoka ethinta umphumela wabo wokubonisa. Yimiphi imishini enokunemba ephezulu edingekayo kwinqubo yokupakisha ukuze wenze umkhiqizo wokubonisa osebenza ngokuphezulu we-LED? Ngezansi, sizokwethula kafushane ukusebenza kwemibukiso ye-LED.
Amandla we-antistatic
I-LED ingeyamadivayisi we-semiconductor futhi inaka ugesi ojwayelekile, ongaholela kalula ekuhlulekeni okulo. Ngakho-ke, ikhono le-anti-tuli libalulekile kwisikhumbuzo sokuphila kwe-LED. I-voltage yokwehluleka kokuhlolwa kwemodi kagesi kagesi yakwa-LED akufanele ibe ngaphansi kune-2000V.
Izici ze-Attenuation
Ngokuvamile, izikrini zokubonisa ze-LED zidinga umsebenzi wesikhathi eside, ezingaholela ekunciphiseni ekukhazimuleni nasemibalani yokubonisa engahambisani, konke okubangelwa ukuvela kokukhanya kwamadivayisi aholwa. Ukufakwa kokukhanya kwe-LED kubangela ukwehla kokukhanya kwesikrini sonke se-LED. I-aclitude ekhanyayo egqamile ye-atchituation ebomvu, eluhlaza okwesibhakabhaka, futhi i-LED eluhlaza iholela emibalani engavumelani esikrinini sokubonisa esiholayo, okuholela emcimbini wokuhlanekezela kwesikrini. Isikrini esibukweni sekhwalithi ephezulu singalawula ngempumelelo i-amplitude yokuphakama futhi silungise ukukhanya kwayo.
Ukugqama
Ukukhanya kobuhlalu be-LED bokubonisa ubuhlalu kuyinto ebalulekile ekunqumeni ukuphakama kwesikrini sokubonisa. Lapho kukhuphuka ukukhanya kwe-LED, kukhuliswa okukhulu kwamanje okusetshenzisiwe, okuzuzisa ukonga amandla nokugcina ukuqina kwe-LED. Uma i-chip isibekiwe, incane i-angle ye-LED, okugqagele ukugqama kwe-LED. Uma i-angle yokubuka yesikrini sokubonisa incane, i-100 degree LED kufanele ikhethwe ukuze kuqinisekiswe i-angle eyanele yokubuka kwesikrini sokubonisa.Izikrini zokubonisa ze-LEDNge-spacesing ehlukile kanye nomugqa ohlukile wokubona kufanele ucabangele ukugqama, i-angle, nentengo yokuthola iphuzu lokulinganisa.
I-angle yokubuka
I-angle yamahlalu aholwayo inquma i-angle yokubuka yesikrini sokubonisa esiholayo. Njengamanje, iningi le-LED LED lisebenzisa ubuhlalu be-elliptical ball beads nge-angle yokubuka evundlile yama-degree ayi-120 kanye ne-engela yokubuka okuqondile yama-degrees angama-70. Isibonelo, izikrini zokubonisa ze-LED emigwaqweni emikhulu sebenzisa i-LED eyindilinga nge-angle yokubuka degree engama-30. Izikrini zokubonisa eziholwayo ezakhiweni eziphakeme kakhulu zidinga i-angle ebukeke mpo, futhi ama-engeli akhudlwana akhudlwana anciphisa ukukhanya. Ngakho-ke ukukhetha kombono kuya ngenhloso ethile.
Izinga lokuhluleka
Isikrini esibonisa sombala esigcwele sakhiwa amaphikseli aqukethe amashumi ezinkulungwane noma amakhulu ezinkulungwane zezinto ezibomvu, eziluhlaza okotshani, kanye ne-LED eluhlaza okwesibhakabhaka. Ukwehluleka kwanoma iyiphi i-LED yombala kuzoholela emphumeleni wokubuka wesikrini sokubonisa.
Phina
Isikrini sokubonisa esisebenza ngombala ogcwele sakhiwa amaphikseli angenakubalwa ahlanganiswe abomvu, aluhlaza okwesibhakabhaka, kanye ne-LED eluhlaza. Ukukhanya kanye ne-wavelength yombala ngamunye we-LED kudlala indima enqumayo ekukhazimuleni, ukuguquguquka okuningana okulinganiselayo, nokuvumelana kokukhanya kwesikrini sokuboniswa kwesibonisi. I-LED inama-angles, izikrini zokubonisa ezinemibala egcwele futhi zinomqondo we-angle. Lapho kubukwa kusuka kuma-engeli ahlukene, ukukhanya kwawo kuzokhuphuka noma kwehle. Ukuguquguquka kwe-angle yokubomvu, okuluhlaza okotshani, kanye ne-Blue LED kuthinta kakhulu ukungalingani okulinganiselwe okumhlophe ngama-angles ahlukene, okuthinta ukwethembeka kombala wamavidiyo we-LED Display Screen. Ukufeza ukungaguquguquki kokuqhathanisa ukuguquguquka kokukhanya okubomvu, okuluhlaza okotshani, kanye nohlaza okwesibhakabhaka kuholele emangele ehlukene, kuyadingeka ukuklama ilensi ehlanganisiwe ukwakhiwa kwesayensi kokukhethwa kwezobuchwepheshe kuncike kumazinga obuchwepheshe. Lapho ukuguquguquka kwama-angles aholwa kumpofu, umphumela wokulinganisa omhlophe wesikrini sokubonisa esiholayo kuma-engeli ahlukene awethemba.
Isikhathi sokuphila
Isilinganiso esijwayelekile sokuphila kwezikrini zokubonisa ama-LED zingamahora ayi-100000. Uma nje ikhwalithi yamadivayisi aholwayo ilungile, okusebenzayo okusebenzayo kufanelekile, ukwakheka kokushisa okushisa kunengqondo, futhi inqubo yokukhiqiza yezikrini zokubonisa eziholwayo zingenye yezindlela ezihlala isikhathi eside ku-LED Display Screens. Intengo yamadivayisi aholwa ama-akhawunti ama-70% entengo yezikrini zokubonisa ze-LED, ngakho-ke ikhwalithi yezikrini zokubonisa eziholwayo zinqunywa ngamadivayisi aholwa.
Ubungako
Ubukhulu bamadivayisi aholwayo buhlobene futhi futhi bubalulekile, njengoba buthinta ngqo ibanga le-pixel, ie resolution, izikrini zokubonisa ze-LED. Ngokuvamile, izibani ze-oval ezingama-5mm zisetshenziselwa izikrini zokubonisa ezingaphandle ngenhla kwe-P16, kanti izibani ze-oval ezingama-3mm zisetshenziselwa izikrini zokubonisa zangaphandle ze-P12.5, P12, futhiI-P10. Lapho izikhala zihlala zihlala zihlala zinjalo, zanda usayizi wamadivayisi aholwa ngaphandle zingandisa indawo yazo yokubonisa futhi zinciphise ukudliwa.
