Liyini izinga lokuvuselela isikrini se-LED? Bangaki?

Manje uhlelo lokubonisa i-LED lwangaphakathi nangaphandle luya ngokuya luyanda, noma ngabe isikhumulo sezindiza, izitolo, amagumbi enkomfa nezitudiyo ziyakwazi ukubona isibalo sesibonisi esiholayo. Ukuthi ekuthengeni kwephikseli led led kungase kubuze ukuthi izinga lokuvuselela isikrini, izinga lokuvuselela lingaki amagama, ukuthi namuhla ukukhuluma nge-LED Screen refresh Rate.

Liyini izinga lokuvuselela isikrini se-LED?

Isilinganiso sokuvuselela isibonisi se-LED, esikwaziwa nangokuthi “imvamisa yokuvuselela okubonwayo”, “imvamisa yokuvuselela”, Izinga lokuvuselela isikrini se-LED lisho izinga lokubuyekezwa kwesikrini, okungukuthi, libhekisela esikrinini esiboniswa ngomzuzwana ngenani lezikhathi lapho isikrini Mu siphinda isibonisi, izinga lokuvuselela isikrini kumayunithi e-Hertz, ngokuvamile afushaniswa ngokuthi “Hz”. Ivamise ukufushaniswa ngokuthi “HZ”. Isibonelo, isilinganiso sokuvuselela isikrini esingu-3840Hz sisho ukuthi isithombe sivuselelwa izikhathi ezingu-3840 ngomzuzwana owodwa. Lapho uthatha izithombe noma amavidiyo okuqukethweIsikrini sokubonisa se-LED, ithole ukuthi izithombe abazithathile noma izithombe ezirekhodiwe zinemigqa eqondile noma evundlile noma ezifiphele, kusho ukuthi Izinga lokuvuselela isikrini se-LED yesipoki.

Yiziphi izilinganiso zokuvuselela ezivamile zesibonisi se-LED?

Amazinga okuvuselela avamile afana no-960Hz, 1920Hz, 2880Hz, 3840Hz, njll. ngokuvamile asetshenziselwa ukubonisa okuholelekile okuncane. I-960Hz ivame ukubizwa ngokuthi ibhulashi eliphansi, i-1920Hz ibizwa ngokuthi ibhulashi lomhlaba wonke, i-3840Hz ibizwa ngokuthi ibhulashi eliphezulu. Ngokuvamile izinga eliphezulu lokuvuselela lisetshenziselwa kakhulu ukuthuthukisa ikhwalithi yesithombe, ukunciphisa ukuklebhuka nokufiphala kwesithombe, ikakhulukazi kwezinye izimo zezinhlelo zokusebenza ezichwepheshile, njengokudlalwa kwesiteji, imiqhudelwano, amabhodi okukhangisa, nezindawo ezidinga ukubhekwa kwevidiyo kwekhwalithi ephezulu.Ubudlelwano phakathi kokuvuselela kwe-LED isilinganiso kanye nekhwalithi yesithombe nayo ibaluleke kakhulu, futhi izinga eliphezulu lokuvuselela linganciphisa ngempumelelo ukufiphala kokunyakaza nokuhudula, futhi kuthuthukise ukucaca nokuba ngokoqobo kwesithombe. Ngakho-ke, izinga lokuvuselela liyipharamitha ebaluleke kakhulu okufanele uyinake lapho ukhetha isibonisi esiholwa yi-pitch.

Uyini umthelela wezinga lokuvuselela isikrini esiholayo?

Izinga lokuvuselela i-LED liyisici esibalulekile esithinta ikhwalithi yesikrini nomthelela obonakalayo. Ngokuvamile, imvamisa yokubuka kabusha engu-3,000Hz noma ngaphezulu isibonisi se-LED esisebenza kahle kakhulu. Izinga lokuvuselela eliphezulu linomthelela omkhulu kakhulu ekusebenzeni nakwikhwalithi yesithombe yesibonisi se-LED. 1920Hz, 2880Hz, 3840Hz, njll. Lezi zinga lokuvuselela eliphezulu zinganikeza ukuboniswa kwesithombe okushelelayo nokucacile, okunobungane kakhulu ekuboniseni ukunyakaza okushesha kwezinto, okuqukethwe kwe-paradigm okuguquguqukayo okuphezulu, kanye nokusetshenziswa kwezimfuneko zokunemba kombala ophezulu. Izinga eliphezulu lokuvuselela Isibonisi se-LED sifanele izinhlelo zokusebenza ezidinga ukuzizwisa okubonakalayo okuphezulu kanye nezikhathi zobungcweti, kuyilapho izibonisi zenhloso evamile, izinga lokuvuselela eliphansi selivele lanele.

Lapho imvamisa yokuvuselela iphezulu, isibonisi sesikrini sizinze kakhulu, kuncane ukucwayiza okubonakalayo, ikhwalithi ephezulu yesithombe abantu abasibonayo, nokudlalwa kwevidiyo nakho kuba bushelelezi kakhulu. Izimo ezishiwo ngaphambilini uma uthatha izithombe noma urekhoda okuqukethwe kwevidiyo I-LED ibonisa imigqa evundlile evundlile, okubonisa ukuthi imvamisa ephansi yokuvuselela yesibonisi se-LED iphansi kakhulu. imvamisa ephansi yokuvuselela yesibonisi se-LED izoholela kuvidiyo, ezithombeni, kunemigqa evundlile evundlile ngaphandle noma usidonse usiklebhule isithombe, kodwa futhi kwenzeka ngokufana namashumi ezinkulungwane zamalambu okukhanya ngesikhathi esifanayo isithombe esicwayizayo. Ngakho-ke iso lomuntu ekubukeni lingase likhiphe ukungakhululeki, futhi libangele nokulimala kwamehlo.

Umehluko phakathi kokuvama kokuvuselela kwesibonisi se-LED nokulungiswa

Ukulungiswa kwesikrini se-LED kubhekisela enanini lamaphikseli abonakala esibukweni, ngokuvamile achazwa njengenani lamaphikseli avundlile x nenani lamaphikseli aqondile, afana no-1920 x 1080. Ukulungiswa okuphezulu kusho amaphikseli engeziwe kusikrini sokubonisa se-LED, ukuze sikwazi ukubonisa. imininingwane eyengeziwe yesithombe nokucaca okuphezulu, futhi uzizwe ngemininingwane imininingwane yekhwalithi yesithombe yencazelo ephezulu.Imvamisa yokuvuselela isikrini se-LED sigxile ekuthuthukisweni kwesithombe Izinga lokuvuselela lesibonisi se-LED ligxile esivinini sokubuyekezwa kwesithombe, kanye nokulungiswa igxile ekucaceni nasemininingwaneni yesithombe. Ukuhlanganiswa kwakho kokubili kunomthelela omkhulu ekusebenzeni kwesibonisi nolwazi lomsebenzisi, ngakho-ke lapho ukhetha isibonisi se-LED sidinga ukulinganisela imvamisa yokuvuselela nokulungiswa ngokuya ngokusetshenziswa okukhethekile nesidingo, izimo zohlelo lokusebenza ezihlukene zidinga ukusebenza kwesibonisi okuhlukile, okudingeka abasebenzisi ngokuya ngokusetshenziswa kwezimo kanye nezabelomali ukuze bangene ebucayini ukuze bathole umphumela ongcono wokubonwayo.
Okwesibili. Ingabe ingqikithi yomehluko, izinga lokuvuselela isibonisi se-LED kanye ne-chip yomshayeli we-LED, lapho ukusetshenziswa kwe-chip evamile, izinga lokuvuselela lingafinyelela kuphela ku-480Hz noma 960Hz, kuyilapho isibonisi se-LED sisetshenziswa ku-chip yomshayeli okhiye kabili, bese izinga lokuvuselela. ingafinyelela ku-1920HZ, lapho ukusetshenziswa kwe-chip yomshayeli we-PWM yezinga eliphezulu, izinga lokuvuselela isibonisi se-LED lingafinyelela ku-3840Hz. Isixazululo sesibonisi se-LED sihlobene nosayizi obonakalayo wesibonisi se-LED, usayizi wesibonisi se-LED mkhulu, uphakama ukulungiswa, ngaphezu kwesinqumo kuhlobene nokuphakama kobuhlalu be-LED, kuncane iphimbo ephakeme isixazululo.

Isiphetho

Uma sivame ukubuka isikhathi sokubonisa i-LED asiside, futhi azikho izidingo zokudubula, khona-ke ukusetshenziswa kwezinga eliphansi lokuvuselela kungaba, uma ngokuvamile udinga ukubuka isikhathi eside, futhi ngokuvamile udinga ukuthatha izithombe noma ukudubula ividiyo. ukuze ubuke, kuzomele usebenzise izinga eliphezulu lokuvuselela isibonisi se-LED. Izinga eliphezulu lokuvuselela intengo yesiboniso se-LED iphakeme kakhulu kunezinga eliphansi lokuvuselela, ngakho ukukhetha okuqondile ukuthi yiliphi izinga lokuvuselela lomkhiqizo, noma ngokuya ngokusetshenziswa okukhethekile kokubuka, ngokuya ngezidingo ezahlukahlukene zohlelo, khetha isibonisi esisebenza ezigcawini ezithile. , ukuze kuzuzwe umphumela wokubonwayo ongcono kakhulu nolwazi lomsebenzisi. Isibonisi se-LED sokuvuselela okuphansi singamehlo okubuka hhayi umthelela omningi, akubonwa ukuthi isikrini siyacwayiza, asikho isidingo sokuthatha izithombe noma amacala evidiyo awanawo umthelela, angonga isabelomali esiningi, yebo, uma ikhwalithi yesithombe Izimfuneko zezigcawu eziqondile eziphakeme kakhulu noma isabelomali sezindleko sanele, bese ukhetha ngokwemvelo izinga lokuvuselela eliphezulu lesibonisi se-LED kungcono.
