Ngokuthuthuka okusheshayo kwe-Isikrini sokubonisa se-LEDembonini, izibonisi ze-LED nazo ziya ngokuya zithandwa ngabantu.Njengemfundamakhwela, ungayihlukanisa kanjani ikhwalithi yezibonisi ze-LED?
Ukukhanya
Ukukhanya kuyinkomba ebaluleke kakhulu yezikrini zokubonisa ze-LED, ezinquma ukuthi isikrini se-LED singabonisa yini izithombe ezinencazelo ephezulu.Lapho ukukhanya kuphezulu, kulapho kucaca khona isithombe esivezwa esikrinini esiboniswayo.Ngokulungiswa okufanayo, lapho ukukhanya kuyancipha, isithombe esivezwa esibukweni sifiphala kakhulu.
Ukukhanya kwezikrini ze-LED ngokuvamile kukalwa ngezinkomba ezilandelayo:
Ezindaweni zasendlini, kufanele ifinyelele ku-800 cd/㎡ noma ngaphezulu;
Ezindaweni ezingaphandle, kufanele ifinyelele ku-4000 cd/㎡ noma ngaphezulu;
Ngaphansi kwezimo zezulu ezihlukile, isikrini sokubonisa i-LED kufanele siqinisekise ukukhanya okwanele futhi sikwazi ukusebenza ngokuqhubekayo amahora angaphezu kwangu-10;
Uma ungekho umoya, isikrini se-LED akufanele sibonise ukukhanya okungalingani.
Umbala
Imibala yezikrini zokubonisa ze-LED ihlanganisa ikakhulukazi: ubuningi bombala, ileveli ye-grayscale, usayizi wombala we-gamut, njll. Ngenxa yomehluko ekuhlanzekeni kombala, umbala ngamunye unezinga lawo kanye nezinga elimpunga, futhi singakhetha imibala ehlukene ngokuya ngezidingo ezihlukene.Izinga elimpunga liphinde libe ngesinye sezinkomba ezibalulekile ezithinta ikhwalithi yezikrini zokubonisa ze-LED.Imele ukukhanya nobumnyama obuqukethwe umbala.Uma iphezulu ileveli ye-grayscale, umbala uzoba mncane, futhi izozwakala icace uma ibukwa.Ngokuvamile, izikrini ezibonisa i-LED zibonisa izinga elimpunga elingu-16, elingasetshenziswa ukunquma ukuthi ikhwalithi yezikrini zokubonisa ze-LED yinhle yini.
Ukufana kokukhanya
Ukufana kokukhanya kwezikrini zokubonisa ze-LED kubhekisela ekutheni ingabe ukusatshalaliswa kokukhanya phakathi kwamayunithi aseduze kuyafana yini phakathi nesibonisi esinombala ogcwele.
Ukufana kokukhanya kwezikrini zokubonisa ze-LED ngokuvamile kuhlulelwa ngokuhlolwa okubukwayo, okuqhathanisa amanani okukhanya ephoyinti ngalinye kuyunithi efanayo phakathi nesibonisi esinombala ogcwele namanani okukhanya ephoyinti ngalinye kuyunithi efanayo ngesikhathi sokuboniswa okuhlukahlukene okunemibala egcwele.Amayunithi anokukhanya okungekuhle noma okungekuhle avame ukubizwa ngokuthi "amabala amnyama".Isofthiwe ekhethekile ingasetshenziswa futhi ukukala amanani okukhanya phakathi kwamayunithi ahlukene.Ngokuvamile, uma umehluko wokukhanya phakathi kwamayunithi udlula u-10%, kuthathwa njengendawo emnyama.
Ngenxa yokuthi izikrini zokubonisa ze-LED zakhiwe ngamayunithi amaningi, ukufana kwazo kokukhanya kuthinteka kakhulu ekusabalaleni okungalingani kokukhanya phakathi kwamayunithi.Ngakho-ke, ukunakwa okukhethekile kufanele kukhokhwe kulolu daba lapho ukhetha.
I-engeli yokubuka
I-Visual angle isho i-engeli enkulu lapho ungabona khona konke okuqukethwe kwesikrini kuzo zombili izinhlangothi zesikrini.Usayizi we-engeli yokubuka unquma ngokuqondile izethameli zesikrini esibonisiwe, ngakho-ke inkulu iba ngcono.I-engeli ebonakalayo kufanele ibe ngaphezu kwama-degree angu-150.Ubukhulu be-engeli yokubuka ikakhulukazi kunqunywa indlela yokupakisha ye-tube core.
Ukukhiqizwa kombala
Ukukhiqizwa kombala kubhekisela ekushintshashintsheni kombala wezikrini zokubonisa ze-LED ezinoshintsho ekukhanyeni.Isibonelo, izikrini ze-LED zibonisa ukukhanya okuphezulu ezindaweni ezimnyama kanye nokukhanya okuphansi ezindaweni ezikhanyayo.Lokhu kudinga ukucutshungulwa kokukhiqizwa kabusha kombala ukwenza umbala uboniswe kuzikrini zokubonisa ze-LED eduze nombala esigcawini sangempela, ukuze kuqinisekiswe ukuzalaniswa kombala esigcawini sangempela.
Okungenhla yizinyathelo okufanele sizithathe lapho sikhetha izikrini zokubonisa ze-LED.Njengomkhiqizi wesikrini esibonisiwe se-LED ochwepheshe, siyazethemba futhi siyakwazi ukukunikeza ngezikrini zokubonisa ze-LED zekhwalithi ephezulu.Ngakho-ke, uma unezidingo zokuthenga, sicela usithinte ngokuqondile futhi sizokuphendula ngokushesha ngangokunokwenzeka.Ngibheke ngabomvu ukusebenza nawe!
