Isilinganiso sokuqabuleka kweIzikrini zokubonisa ze-LEDiparamitha ebaluleke kakhulu. Siyazi ukuthi kunezinhlobo eziningana zamanani wokuvuselela izikrini zokubonisa eziholwayo, ezinjenge-480hz, 960hzz, ngo-1920hz, njll., Ezibhekiselwa kuzo njengebhulashi eliphansi embonini. Ngakho-ke buyini ubudlelwano phakathi kwezinga lokuqabuleka kwezikrini zokubonisa ze-LED? Yini enquma isilinganiso sokuqabula? Kunamuphi umthelela kokuhlangenwe nakho kwethu kokubuka? Ngaphezu kwalokho, yini isilinganiso esifanele sokuqabula sokuvuselela okuholwa esikrinini esikhulu? Le yiminye imibuzo enobungcweti, futhi abasebenzisi bangabuye badideke lapho bekhetha. Namuhla, sizonikeza impendulo eningiliziwe yombuzo wezinga lokuvuselela le-LED!
Umqondo wokuvuselela isilinganiso
Isilinganiso sokuqabuleka kweIsikrini sokubonisaKubhekiswa kwinani lezikhathi isithombe esibonisiwe sikhonjiswa kaningi esikrinini ngomzuzwana, silinganiswe ku-HZ, esaziwa nangokuthi uHertz. Isibonelo, isikrini sokubonisa esiholayo esinesilinganiso sokuvuselela sango-1920 sibonisa amahlandla we-1920 ngomzuzwana. Izinga lokuvuselela ikakhulukazi lithinta inkomba enkulu yokuthi ama-flickers wesikrini ngesikhathi sokuboniswa, futhi ikakhulukazi athinta izici ezimbili: umphumela wokudubula kanye nesipiliyoni sokubuka umsebenzisi.
Yini ephakeme futhi ephansi ukuvuselela?
Ngokuvamile, izinga lokuvuselela lemibukiso ye-LED yombala owodwa neyembili le-480hz, kuyilapho kunezinhlobo ezimbili zamanani wokuvuselela athola imibukiso eholwa ngombala ogcwele: 960hz, ngo-3840hz. Ngokuvamile, 960hz no-1920HZ babizwa ngokuthi ngamanani okuqabula aphansi, futhi 3840hz kubhekiselwa kuwo njengamazinga wokuvuselela aphezulu.
Yisiphi isilinganiso sokuqabuleka kwezikrini zokubonisa eziholwayo ezihlobene?
Izinga lokuvuselela lezi zikrini zokubonisa eziholwayo zihlobene ne-chip ye-LED Driver. Lapho usebenzisa i-chip ejwayelekile, izinga lokuqabuleka lingafinyelela kuma-480hz noma nge-960hz. Lapho isikrini esibonisa isibonisi sisebenzisa i-Chip ekhiya i-Dual yokukhiya, izinga lokuqabuleka lingafinyelela ngo-1920hz. Lapho usebenzisa i-chip ye-pwm ephakeme ye-PWM ye-PWM, izinga lokuvuselela lesikrini sokubonisa esiholayo lingafinyelela ku-3840hz.
Sithini isilinganiso esifanele sokuqabula?
Ngokuvamile, uma kungukubonisa kwesikrini esisodwa noma ezimbili sombala we-LED. Kodwa-ke, uma kuyisikrini esikhanyayo esinemibala egcwele, kungcono ukufeza isilinganiso sokuqabuleka kuka-1920HZ, esingaqinisekisa isipiliyoni esijwayelekile sokubuka futhi sivikele ukukhathala okubonakalayo ngesikhathi sokubukwa isikhathi eside. Kepha uma kuvame ukusetshenziselwa ukudubula nokuphakanyiswa, kungcono ukwenza isikrini sokubonisa esiholayo ngesilinganiso esiphakeme sama-3840hz, ngoba isikrini sokubonisa esiholayo esinezilinganiso zamanzi ngesikhathi sokudubula, okuholela emiphumeleni yezithombe ezingcono futhi ezicacile.
Umthelela wamazinga aphezulu okuqabuleka aphansi naphansi
Ngokuvamile, inqobo nje uma izinga lokuqabuleka kwezikrini zokubonisa ze-LED liphakeme kune-960hz, licishe livikelekile yiso lomuntu. Ukufinyelela ngo-2880hz noma ngaphezulu kubhekwa njengokusebenza kahle. Izinga lokuvuselela eliphakeme lisho ukuthi isibonisi sesikrini sizinzile, ukunyakaza kubushelelezi futhi kungokwemvelo, futhi isithombe sicace. Ngasikhathi sinye, ngesikhathi sokuthwebula izithombe, isithombe esikhonjiswe kwizikrini zokubonisa ama-LED asinazo izimbambo zamanzi, futhi iso lomuntu ngeke lisakwazi ukuzizwa lingakhululekile lapho bebukele isikhathi eside, benza ukukhathala okubonakalayo mancane.
Ngakho-ke izinga lokuqabuleka kwesikrini sethu sokubonisa esiholayo ikakhulukazi kuya ngenhloso yethu nohlobo lwe-LED olusetshenzisiwe. Uma kungumbala owodwa noma oyedwa oholwa kabili, asikho isidingo sokunaka kakhulu isilinganiso sokuqabuleka. Kodwa-ke, uma kungenye yezikrini eziholwa imibala ezinemibala egcwele ngaphakathi, kusetshenziswa isilinganiso sokuvuselela esingu-1920HZ futhi sanele, futhi manje sisetshenziswa kabanzi. Kepha uma uvame ukudinga ukuyisebenzisa ngokudubula kwevidiyo noma izinhloso zokuphromotha, zama ukusebenzisa isilinganiso sokuvuselela esiphakeme se-3840hz.
