Onetsani mtengo wotsitsimutsa zayamba kumveka pafupipafupi masiku ano. Mawu awa, omwe ogwiritsa ntchito ambiri samadziwa mpaka zaka zingapo zapitazo, tsopano atchuka chifukwa cha kusintha kwa mawonekedwe otsitsimutsa pazida zam'manja. Mawonekedwe otsitsimula amayezedwa mu Hertz (Hz) ndipo akuwonetsa kuchuluka kwa mafelemu pa sekondi iliyonse yomwe chipangizocho chimawonetsa pachiwonetsero. Chida chotsitsimutsa kwambiri chingapangitse kusiyana kwakukulu. Chifukwa idzapereka chidziwitso chochuluka chamadzimadzi. Kuphatikiza apo, mawu omwe timatcha FPS (frame-per-sekondi) amadalira kwathunthu. Ndiye pali malingaliro otani pamlingo wotsitsimutsa zenerali? Zikuyenda bwanji? Chifukwa chiyani chiwonetsero chapamwamba chotsitsimutsa chimakondedwa pazida zoyambira?
Kusiyana kwa Mawonedwe Otsitsimutsa Owonetsera
Zithunzi zimasinthidwa pafupipafupi pazenera la chipangizo chilichonse. Muzosinthazi, kuchuluka kwa mafelemu otsatizana pa sekondi iliyonse kumawonetsedwa ndi mtengo wotsitsimutsa. Mwachitsanzo, chophimba cha 30Hz chimabweretsa mafelemu 30 pa sekondi iliyonse. Ndipo chiwonetsero cha 60Hz chimabweretsa mafelemu 60 osiyanasiyana pamphindikati. Ogwiritsa sangathe kuwona mafelemu awa payekhapayekha, koma apereka chidziwitso chosalala kwambiri pakugwiritsa ntchito tsiku ndi tsiku.
Kuti mufotokoze mwatsatanetsatane, pali kuchedwa kwa pafupifupi 33.33ms pakati pa masinthidwe azithunzi pazithunzi za 30Hz. Kuchuluka kotsitsimutsa, kumachepetsa mtengowo komanso mafelemu ambiri pamphindikati, ndi zambiri. Pa chiwonetsero cha 120Hz, kuchedwa pakati pa mafelemu ndi pafupifupi 8.33ms. Pali kusiyana kwakukulu.
Lingaliro la FPS, lomwe limadziwika kwambiri makamaka ndi osewera, limadalira kwenikweni. Mitengo yotsitsimutsa imapanga kusintha kwakukulu ngakhale ndi kusiyana kochepa kwambiri. Ngakhale kusiyana kochepa pakati pa 60Hz ndi 75Hz kumapereka chidziwitso chabwinoko kwa osewera. Komanso, mawonekedwe otsitsimutsa pazenera la chipangizo chanu ndiye FPS yayikulu kwambiri yomwe mungakumane nayo. Mwachitsanzo, muli ndi chowunikira cha 144Hz ndipo mukusewera masewera. Ngakhale kompyuta yanu yamphamvu ikupereka 200-300 FPS mumasewerawa, mtengo womwe mungakhale nawo ndiwopambana. Zithunzi za 144FPS. Chifukwa chake, popeza chowunikira cha 144Hz chimatha kutulutsa mafelemu 144 pamphindikati, zambiri sizingatheke.
Kusintha kwa Mawonekedwe Otsitsimutsa
Mitengo yotsitsimutsa yasintha kwambiri pazaka zingapo zapitazi. Komabe, zaka zapitazo (ngakhale lero), zowonetsera 60Hz zinali zokhazikika. Zowunikira za 75Hz zinalipo panthawiyi. Palibe kudumpha kwakukulu pakati, komabe owunikira ambiri akale a CRT amathandizira 75Hz. Kusintha kwakukulu kunabwera ndi 120 Hz yotsitsimutsa. BenQ's XL2410T LED monitor ndiye woyamba padziko lonse lapansi pamasewera a 120Hz. Chowunikira cha kukula kwa mainchesi 24 chinatulutsidwa mu Okutobala 2010. Mwanjira ina, titha kunena kuti polojekiti yoyamba ya 120Hz idakumana ndi ogwiritsa ntchito mu 2010.
Zaka 2 pambuyo pake, wowunikira woyamba padziko lonse lapansi wa 144Hz adakumana ndi ogwiritsa ntchito, ASUS VG278HE. Kuwunika ndi kukula kwa mainchesi 27 ndi Full HD (1920 × 1200) kusamvana kunali ndi kutsitsimula kwa 144Hz. Idatulutsidwa mu Julayi 2012. Mtengo wotsitsimula wa 144Hz udali wosintha kwa eni ma monitor a 60Hz. Kenako idapitilirabe bwino, kutsitsimula kwa 165Hz kudakwaniritsidwa mu February 2016, kenako 240Hz idakwaniritsidwanso. Ngakhale pano, pali zowunikira zomwe zilipo zotsitsimutsa 360Hz. Mtundu wa ASUS ROG Shift PG259QNR ungakhale chitsanzo chabwino.
Zowonadi, zomwe zikuchitika mu oyang'anira zidawonekeranso mwachindunji m'mabuku. Nthawi yomweyo, zolemba zolembera zidasinthidwa kukhala zowonetsa zotsitsimutsa kwambiri. Ma laptops amasewera akutsogolera pankhaniyi. Mwachitsanzo, laputopu yachilombo ya Monster Tulpar T7 V25.1.2 ili ndi chiwonetsero cha 17-inch 300Hz. Umu ndi momwe kusinthika kwamawonekedwe otsitsimutsa pamakompyuta kulili, koma nanga bwanji mafoni kapena mapiritsi? Kodi timadziwa za kutsitsimula kwa mafoni athu?
Kusintha kwa Mawonekedwe Otsitsimutsa Mafoni
Pakhala zokamba zambiri za izi pamsika wa smartphone posachedwa. M'malo mwake, zaka zingapo zapitazo, chiwonetsero chotsitsimutsa sichinali chofunsidwa pama foni. chifukwa zida zonse zinali kubwera ndi chiwonetsero cha 60Hz. Mawonekedwe apamwamba otsitsimutsa sanapezeke, kapena mwina osafunikira pakugwiritsa ntchito tsiku ndi tsiku, mpaka 2017.
Chipangizo choyamba chokhala ndi chiwonetsero chapamwamba chotsitsimutsa chinali Razer Phone, yomwe inayambitsidwa mu November 2017. Ichi chinali kusuntha koyenera kwa makampani othamanga omwe akukwera mofulumira padziko lonse lapansi. Pamodzi ndi ma chipsets amphamvu kwambiri, masewera amafoni apamwamba kwambiri amafunikira. Razer Foni idayendetsedwa ndi Qualcomm's Snapdragon 835 (MSM8998) chipset. Chipangizochi, chomwe chili ndi chophimba cha 5.7 ″ 120Hz QHD (1440 × 2560) IPS LCD (IGZO), ndiye chida choyamba chowonetsera zotsitsimutsa kwambiri padziko lonse lapansi.
Kenako ukadaulo uwu pang'onopang'ono unayamba kuyenda pazida zam'manja. Chipangizo choyamba cha 90Hz ndi Asus ROG Phone, foni ina yamasewera yomwe inatulutsidwa mu October 2018. Mothandizidwa ndi Qualcomm's Snapdragon 845 (SDM845) chipset, chipangizocho chinali ndi 90Hz FHD + (1080 × 2160) chiwonetsero cha AMOLED. Ichi chinali chida china chokhala ndi lingaliro lamasewera. Mwachiwonekere, makampani amasewera ndichinthu chofunikira kwambiri pakukula kwa chiwonetsero chazithunzi. Zambiri zokhudzana ndi chipangizochi zilipo Pano.
Mu 2019, kutsitsimuka kwakukulu, komwe kunasiya pang'onopang'ono kukhala chinthu chamasewera, kudayamba kukumana ndi ogwiritsa ntchito kumapeto. Zida zoyamba zoperekera zotsitsimutsa kwambiri pakugwiritsa ntchito tsiku ndi tsiku zidachokera ku OnePlus ndi Google. Chipangizo cha OnePlus 7 Pro chomwe chinayambitsidwa mu Meyi 2019 ndi zida za Google Pixel 4 ndi Pixel 4 XL zomwe zidatulutsidwa mu Okutobala 2019 ndi zina mwa zida zoyambira kupereka mitengo yotsitsimula kwambiri yogwiritsidwa ntchito tsiku ndi tsiku. Chipangizo choyamba cha Xiaomi chotsitsimutsa chophimba kwambiri ndi chipangizo cha Redmi K30 chopangidwa ndi Redmi. Chipangizocho, chomwe chili ndi chiwonetsero cha 120Hz chotsitsimutsa, chidatulutsidwa mu Disembala 2019. Mutha kudziwa zambiri za Redmi K30. Pano.
Zachidziwikire, mitundu sinakhutire ndi 90Hz ndi 120Hz. Mtengo wotsitsimula wa 144Hz wafika pazida zam'manja. Chipangizo choyamba chokhala ndi chiwonetsero cha 144Hz padziko lapansi ndi ZTE Nubia Magic 5G. Choyambitsidwa mu Marichi 2020, chipangizocho chili ndi chiwonetsero cha 6.65 ″ FHD+ (1080 × 2340) 144Hz AMOLED. Ndipo zida zoyamba za Xiaomi 144Hz ndi zida za Mi 10T ndi Mi 10T Pro. Zida izi zidayambitsidwa mu Okutobala 2020, Mi 10T mndandanda uli ndi 6.67 ″ FHD+ (1080×2400) 144Hz IPS LCD. Mafotokozedwe a Mi 10T ndi Pano, ndi mawonekedwe a Mi 10T Pro ndi Pano.
Pambuyo pazaka za chitukuko, muyezo wa 60Hz tsopano watha, ngakhale pazida zam'manja. Kupanga ukadaulo ndi njira zatsopano zamakampani kudzatiwonetsa zotsitsimutsa zapamwamba. Mawonekedwe apamwamba otsitsimutsa adzapereka mawonekedwe amadzimadzi komanso okhazikika ogwiritsa ntchito. Kuphatikiza apo, chiwonetsero chotsitsimutsa, chomwe chili chofunikira kwambiri kwa osewera, tsopano chakhala chinthu chofunikira pogula foni. Osayiwala kufotokoza malingaliro anu mu ndemanga, ndipo khalani maso kuti mumve zambiri.
