Bonisa izinga lokuvuselela isiqale ukuzwakala kaningi namuhla. Leli temu, iningi labasebenzisi abebengalazi kuze kube yiminyaka embalwa edlule, manje selidume ngokuvela kwezinga lokuvuselela isibonisi kumadivayisi eselula. Izinga lokuvuselela lokubonisa likalwa nge-Hertz (Hz) futhi libonisa inombolo yozimele ngesekhondi ngayinye idivayisi eyibonisa ekubonisweni. Idivayisi enenani lokuvuselela eliphezulu ingenza umehluko omkhulu. Ngoba izonikeza isipiliyoni samanzi amaningi. Ngaphezu kwalokho, igama esilibiza nge-FPS (uhlaka-ngomzuzwana) lincike ngokuphelele kulo. Ngakho-ke iyini ingqondo yalesi silinganiso sokuvuselela isikrini? Isebenza kanjani? Kungani izinga eliphezulu lokuvuselela isibonisi likhethwa kumadivayisi eprimiyamu?
Umehluko Wezilinganiso Zokuvuselela Isibonisi
Izithombe zivuselelwa njalo esikrinini sanoma iyiphi idivayisi. Kulezi zibuyekezo, inombolo yozimele abalandelanayo ngesekhondi ngalinye ivezwa izinga lokuvuselela. Isibonelo, isikrini esingu-30Hz siletha amafreyimu angu-30 ngomzuzwana esikrinini. Futhi isibonisi esingu-60Hz siletha ozimele abahlukene abangu-60 ngomzuzwana. Abasebenzisi ngeke bakwazi ukubona lawa mafreyimu ngabodwana, kodwa izohlinzeka ngomuzwa oshelela kakhulu ekusetshenzisweni kwansuku zonke.
Ukuchaza kabanzi, kukhona ukubambezeleka okungaba ngu-33.33ms phakathi kokushintshwa kozimele kusikrini esingu-30Hz. Izinga lokuvuselela eliphakeme, lenza leli nani libe phansi kanye nozimele abengeziwe ngesekhondi ngalinye, kanye nemininingwane eyengeziwe. Esibonisini esingu-120Hz, ukubambezeleka phakathi kozimele cishe ku-8.33ms. Kunomehluko omkhulu.
Umqondo we-FPS, owaziwa kakhulu ikakhulukazi ngabadlali bamageyimu, uncike ngokuphelele kuwo. Izilinganiso zokuvuselela zidala izinguquko ezimbi kakhulu ngisho noma kunomehluko omncane kakhulu. Ngisho nomehluko omncane phakathi kwe-60Hz kanye ne-75Hz inikeza umuzwa ongcono kubadlali bamageyimu. Futhi, izinga lokuvuselela isikrini sedivayisi yakho ubuningi be-FPS ongayithola. Isibonelo, unemonitha engu-144Hz futhi udlala umdlalo. Noma ngabe ikhompuyutha yakho enamandla inika ama-FPS angu-200-300 kulowo mdlalo, inani ongase ulizwe likhulu. 144 FPS. Ngakho-ke, njengoba imonitha engu-144Hz ingakhipha ozimele abangu-144 ngomzuzwana, okuningi ngeke kwenzeke.
Ukuvela Kwezilinganiso Zokuvuselela Isibonisi
Amazinga okuvuselela aguquke kakhulu eminyakeni embalwa edlule. Kodwa-ke, eminyakeni edlule (ngisho nanamuhla), ukuboniswa okungu-60Hz bekujwayelekile. Amamonitha angu-75Hz abetholakala ngalesi sikhathi. Akukho ukweqa okukhulu phakathi noma kunjalo, futhi abaningi abaqaphi be-CRT abadala basekela i-75Hz. Ukuvela okukhulu kweza nesilinganiso sokuvuselela esingu-120 Hz. I-BenQ's XL2410T yokuqapha i-LED yemodeli iyiqapha lokuqala lemidlalo le-120Hz emhlabeni. Imonitha yosayizi wamayintshi angu-24 ikhishwe ngo-Okthoba 2010. Ngamanye amazwi, singasho ukuthi imonitha yokuqala engu-120Hz ihlangane nabasebenzisi ngo-2010.
Eminyakeni emi-2 kamuva, umqaphi wokuqala we-144Hz emhlabeni wahlangana nabasebenzisi, i-ASUS VG278HE. Ukuqapha ngosayizi wamayintshi angu-27 kanye nesinqumo se-Full HD (1920×1200) sibe nesilinganiso sokuvuselela esingu-144Hz. Ikhishwe ngoJulayi 2012. Izinga lokuvuselela le-144Hz libe nenguquko kubanikazi bokuqapha okungu-60Hz. Yabe iqhubeka nokuba ngcono, izinga lokuvuselela elingu-165Hz lafinyelelwa ngoFebhuwari 2016, kwase kuba i-240Hz nayo ifinyelelwe. Ngisho namanje, akhona ama-monitor atholakalayo anesilinganiso sokuvuselela esingu-360Hz. Imodeli ye-ASUS ROG Shift PG259QNR ingaba isibonelo esihle.
Kunjalo, lokhu kuthuthukiswa kwabaqaphi nakho kubonakale ngqo ezincwadini zokubhalela. Ngesikhathi esifanayo, izincwadi zokubhalela zishintshele ekuboniseni izinga eliphezulu lokuvuselela. Amalaptop emidlalo ahamba phambili kulokhu. Isibonelo, imodeli ephathekayo ye-Monster Tulpar T7 V25.1.2 inesibonisi esingu-17-inch 300Hz. Lena yindlela ukuvela kwesilinganiso sokuvuselela isibonisi kumakhompyutha, kodwa kuthiwani ngama-smartphone noma amathebulethi? Ingabe siyazi ngezinga lokuvuselela amafoni ethu?
Ukuvela Kwezilinganiso Zokuvuselela Ukuboniswa Kwefoni
Sekunezinkulumo eziningi ngalokhu emakethe yama-smartphone muva nje. Eqinisweni, eminyakeni embalwa edlule, izinga lokuvuselela lokubonisa lalingekho umbuzo kumafoni. ngoba wonke amadivayisi abeza nesibonisi esingu-60Hz. Izilinganiso zokuvuselela ezibonisiwe eziphezulu bezingakatholakali, noma mhlawumbe azidingeki ekusetshenzisweni kwansuku zonke, kuze kube ngu-2017.
Idivayisi yokuqala enezinga eliphezulu lokubonisa izinga lokuvuselela kwakuyiRazer Phone, eyethulwa ngoNovemba 2017. Lokhu kwakuyisinyathelo esidingekayo embonini yemidlalo yeselula ekhula ngokushesha emhlabeni. Eceleni kwama-chipsets akhula ngamandla, imidlalo yeselula enezithombe eziphakeme ibikufuna. I-Razer Phone inikwa amandla yi-chipset ye-Qualcomm's Snapdragon 835 (MSM8998). Idivayisi, enesikrini esingu-5.7″ 120Hz QHD (1440×2560) IPS LCD (IGZO), iyidivayisi yokuqala emhlabeni yokubonisa izinga eliphezulu lokuvuselela.
Khona-ke lobu buchwepheshe buqala kancane kancane ukuthambekela kumadivayisi eselula. Idivayisi yokuqala ye-90Hz i-Asus ROG Phone, enye ifoni yomqondo wegeyimu ekhishwe ngo-Okthoba 2018. Inikwe amandla yi-chipset ye-Qualcomm's Snapdragon 845 (SDM845), idivayisi ibe nesibonisi esingu-90Hz FHD+ (1080×2160) AMOLED. Lena bekungenye idivayisi enomqondo wokudlala. Ngokusobala, imboni yezokudlala iyisici esibalulekile ekuthuthukisweni kwezinga lokuvuselela isikrini. Ulwazi oluthe xaxa mayelana nedivayisi luyatholakala lapha.
Ngo-2019, izinga eliphezulu lokuvuselela, eliye layeka kancane kancane ukuba yisici nje sokudlala, laqala ukuhlangana nomsebenzisi wokugcina. Amadivayisi okuqala anikezela ngezinga eliphezulu lokuvuselela ukuze asetshenziswe nsuku zonke avela ku-OnePlus naku-Google. Idivayisi ye-OnePlus 7 Pro eyethulwe ngoMeyi 2019 kanye namadivayisi we-Google Pixel 4 kanye ne-Pixel 4 XL ezethulwe ngo-Okthoba 2019 aphakathi kwamadivayisi okuqala ukunikeza amanani okuvuselela aphezulu ukuze asetshenziswe nsuku zonke. Idivayisi yokuqala ye-Xiaomi yokuvuselela isikrini esiphezulu idivayisi ye-Redmi K30 eyenziwe yi-Redmi. Idivayisi, enezinga lokuvuselela isikrini esingu-120Hz, yakhululwa ngoDisemba 2019. Ungathola ulwazi olwengeziwe mayelana ne-Redmi K30. lapha.
Impela, amabhrendi abenganelisekile nge-90Hz kanye ne-120Hz. Izinga lokuvuselela elingu-144Hz lifinyelelwe kumadivayisi eselula. Idivayisi yokuqala enombukiso we-144Hz emhlabeni i-ZTE Nubia Magic 5G. Yethulwe ngoMashi 2020, idivayisi inesibonisi esingu-6.65″ FHD+ (1080×2340) 144Hz AMOLED. Futhi amadivayisi okuqala e-Xiaomi 144Hz angamadivayisi we-Mi 10T ne-Mi 10T Pro. Lawa madivayisi wethulwa ngo-Okthoba 2020, uchungechunge lwe-Mi 10T lune-6.67″ FHD+ (1080×2400) 144Hz IPS LCD. Imininingwane ye-Mi 10T lapha, kanye nokucaciswa kwe-Mi 10T Pro kukhona lapha.
Ngemuva kweminyaka yokuthuthuka, izinga le-60Hz alisasebenzi, ngisho nakumadivayisi eselula. Ukuthuthukisa ubuchwepheshe kanye nezinqubo zokuqamba ezintsha zezinkampani kuzosibonisa amanani okuvuselela aphezulu. Izinga eliphezulu lokuvuselela isibonisi lizohlinzeka ngolwazi olunzulu ngomsebenzisi oluzinzile. Ngaphezu kwalokho, izinga lokuvuselela lokubonisa, elibaluleke kakhulu kubadlali bamageyimu, manje seliphenduke into ebalulekile lapho uthenga ifoni. Ungakhohlwa ukuveza imibono yakho kumazwana, futhi uhlale ubukele ukuze uthole okwengeziwe.
