Ukuba sithetha nawe malunga I-HiDPI, ngokuqinisekileyo aniyazi into esiyithethayo, kodwa ukuba siyanikhankanya 'Umboniso weretina', usenokuba sele uyazi apho izithonga ziya khona. Ngelixa wonke umntu esazi ngetekhnoloji ye-Apple yoxinaniso oluphezulu, i-HiDPI sisihloko esingaqondwayo ngabantu abaninzi kuba ulwazi esilufumana kwi-Intanethi luyabhidisa. Kule post siza kusombulula amathandabuzo akhoyo malunga neli gama legama elizama ukuba ngumgangatho omtsha.
Ithetha ukuthini iHiDPI?
I-HiDPI imele "Amachaphaza aPhakamileyo nge-intshi nganye", nto leyo ngesiSpanishi izakuguqulela njenge "high pixel density nge-intshi nganye". Igama ekuthengiswe ngalo le teknoloji iyahluka ngokuxhomekeke kumvelisi, kunye 'neRetina' iyinguqulelo efumene eyona hype ebulela ngokuba nenkampani efana neApple ngasemva kwayo.
Ngamafutshane, i-HiDPI iza ukucacisa ukuba kukho a unxulumano olugqibeleleyo phakathi kwepikseli ebonakalayo yesikrini kunye nepixel ebonakalayo. Sukuba nexhala ukuba yonke le nto ivakala isiTshayina kuwe kuba uninzi lwabavelisi kunye nabavelisi beekhompyuter abakayiqondi le ngcamango. Kancinci kamva siza kuchaza ukuba yintoni i-HiDPI equlethwe yimizekelo emininzi apho uya kuba nakho ukuqonda le ngcamango ngokucacileyo.
I-HiDPI ibaluleke ngaphezu kwe-4K
Imarike igcwele iimveliso ezithengiswa ngesisombululo se-4K. Nangona kunjalo, ishishini alizange lenze umsebenzi walo wasekhaya kule ndawo. I-4K ayikho umgangatho, nangona sikholelwa njalo, kwaye ayinalo inani leepixels ezinikezelwe kuyo ubude okanye ububanzi, into eyenzekayo kwimigangatho yangaphambili (480p, 720p kunye ne-1080p).
Ke…Yintoni i-4K? Inkcazo yayo ayibhekiseli kubungakanani besikrini okanye isisombululo, kodwa kwi ifomati yomfanekiso emalunga nama-4.000 eepikseli ezithe tye. Ngokucacileyo, le nkcazo ivelisa okuninzi ukudideka. Umzekelo, umabonakude we-4K yenye ene-3.840 nge-2.160 pixel matrix ene-16: 9 ye-aspect ratio. Kwaye isikrini se-cinema yedijithali ye-4K yi-4.096 nge-2.160 pixels, kunye ne-17: i-aspect ratio ye-9.
ukuxinana ngumba
Ngoku siyaqonda ukuba eyona nkcazo ye-4K ibandakanya uluhlu lwezigqibo ezahlukeneyo malunga ne-4 yezigidi zeepikseli zizonke. Masithi uye kwivenkile yakho ethembekileyo kwaye uthenge ipaneli ye-3840 nge-2160 pixels. Ngaba yi-4K? Ewe. Ingaba sisikrini seHiDPI? Kuxhomekeke kubukhulu bephaneli. masihambe nabambalwa imizekelo ukuyibona ngokucacileyo:
- Ukuba uthetha nge esweni kwikhompyuter kwaye unayo 32 intshi, ngokunokwenzeka yenzelwe ukuba ibonakale kumgama omalunga nemitha. Ngamnye pixel yomzimba kwikhusi iya kuhambelana a pixel ebonakalayo yenkqubo yokusebenza. Ubungakanani besikrini buya kukuvumela ukuba ube namakhulu ee icon kwidesktop yakho. Uyakwazi ukuba nezicelo ezininzi ezivulekileyo ngokunxuseneyo kwaye awuyi kuba neengxaki zokufunda okubhaliweyo nakweyiphi na kwezi windows kuba ifonti iya kufundeka ngokupheleleyo. Kwaye hayi, besingayi kuthetha ngesikrini se-HiDPI, kodwa ye-LoDPI, kuba isikali sayo siyi-1x.
- Ukuba isisombululo sikwi a I-15 intshi yelaptop, sinokuba nengxaki yokwenyani ukuba isikali simiselwe ku-1x. Ubungakwazi ukufunda konke konke kuba bekungekho kulungelelaniswa ukuxinana kwesikrini kunye nojongano lwenkqubo. Kuya kuba ngoko xa kufuneka sivule i ipixel iphindwe kabini, oko kukuthi, i-HiDPI. Oku kuya kubangela ukuba ipixel nganye kwiscreen sethu ibe zine (enye iphinda kabini kwi-X axis yesikrini kwaye enye iphinda-phindwe kabini kwi-Y axis). Ngoku, isikwere ngasinye seepikseli ezine zomzimba kwiscreen sethu ziyakulingana nepixel ebonakalayo ka-1920 ngo-1080 isisombululo, esisisigqibo esisiqhelileyo. Ngokwenza le nkqubo, akuyi kubakho zingxaki zobukhali. Isikali kufuneka silingane ngokugqibeleleyo, okubhaliweyo kufuneka kucace kwaye akufuneki kubekho naluphi na uhlobo lwe icon enomfiliba okanye imenyu kwiscreen sethu.
- Kwaye ukuba sithetha ngekhusi a I-13 intshi yelaptop? Kwi-1x siya kuba nengxaki enkulu ngakumbi kune-15-intshi yelaptop. KUNYE ukuba siphinda kabini ipixels (okt ukuba sifumana 4 ipixels nganye pixel virtual) zonke isaza kubonakala incinci. Ke kwenzeka ntoni ukuba sithatha 3 ngo 3 pixel matrix? Asinakuyisombulula ingxaki, kuba ukuba siguqula ipixel nganye ukuya kwisithoba, siya kuba sihambe kakhulu. Kwezi meko, kuya kufuneka sikhethe isisombululo esahlukileyo somzimba. Yekhusi le 13 intshi, Isisombululo esipheleleyo seHD asifanelekanga. Abavelisi abazimisele malunga neemveliso zabo ngokwembali basebenzise imatrix ye 1.600 ngo 900 pixels. Ke ukwenza isikali esichanekileyo, ilaptop ye-intshi eyi-13 efuna ukuba nesisombululo kufutshane ne-4K kufuneka ibenendawo yolawulo eyi 3.200 by 1.800 pixels. Isenokubonakala ibudenge (ziiphikseli ezingamakhulu ambalwa kuphela ngaphandle kwe-axis nganye), kodwa ukusetyenziswa kwayo kuya kwahluka kakhulu. Izinto ezikwisikrini ziya kuba nomlinganiselo ochanekileyo, ngokungafaniyo ne-3840 nge-2160 pixel matrix, engayi kukhangeleka kakuhle. Owu, kwaye ukuba uyazibuza, isikrini se-13-intshi ene-3.200-by-1.800-pixel panel ayifaneleki njenge-4K. Kodwa ewe yiHiDPI. Unomdla, akunjalo?
Kwenzeka ntoni xa isikrini okanye inkqubo ayixhasi i-HiDPI?
Ngaphaya koko besisandul’ ukukucacisa kwisiqendu esingaphambili, kukho ingxaki eyongezelelweyo xa sithetha ngayo izibonisi ezingaxhasi i-HiDPI, leyo ngendlela, uninzi lwezikrini esizifumana kwiimarike. Ukwenza umzekelo ube lula, khawucinge ukuba sine-laptop ye-intshi ezili-15 phambi kwethu. Siyazi ukuba i-1920 ngo-108o sisisombululo esichanekileyo kwisikrini sale milinganiselo. Kwenzeka ntoni ukuba endaweni yokusebenzisa isikrini seHiDPI (oko kukuthi i3840 by 2160 pixels kumzekelo ongasentla) sisebenzisa i bonisa nge-1,5x isikali endaweni ye-2x? Ewe, ukuze yonke i-interface ihlale kwindawo enye njenge-Full HD, inkqubo kuya kufuneka ilinganiswe amaxesha ayi-1,5.
Kodwa nantsi into engadibanisiyo. Ngaba sele uqaphele? Akunakwenzeka ukuyilungisa. Siza kusondeza kwiscreen kwaye siza kubona iipixels ngokwahlukeneyo. Xa kungekho 4:1, 9:1, okanye 16:1 imaphu, ipixel nganye kufuneka ngoku. ngokomzimba hlala ipixel enesiqingatha. kunye neepikseli zemidiya azikho.
Yenza ntoni le nkqubo? Offset usebenzisa edumileyo ukuhlambalaza, engayeki ukuba a hluza isihluzo eyenza mnyama i-pixel ukulinganisa isiqingatha senqaku esilahlekileyo. Isiphumo yintlekele epheleleyo kwaye xa inikwe ngokubhaliweyo, ingqina ukuba isikrini esixineneyo asikho ngcono. U-Pirelli wayedla ngokuthi "Amandla ngaphandle kokulawula akunamsebenzi", kwaye lo ngumzekelo ocacileyo wokuba abavelisi kufuneka baqale ukubeka iibhetri zabo kunye kwaye baqale ukusebenzisa loo mandla. I-HiDPI ayithengisi, kodwa itywina eliqinisekisa ukuba isisombululo semonitha asikhethwanga ngokungqongqo.
Yintoni umahluko phakathi kwe-HiDPI kunye neRetina Display?
Ukuthetha ngenjongo, akukho nanye. 'Isiboniso seRetina' asiyonto ingaphaya kwegama lentengiso Apple ebhalisiweyo ukubhekisa kwimiboniso yakho ehambelana neHiDPI. Xa i-Apple isithengisela imveliso ene-'Retina Display', uphawu lwe-apile lubhekisa kwinto yokuba isisombululo seemveliso zayo siyilwe ngendlela yokuba. akukho miba yesikali Akukho nxibelelwano lufifi. Basebenzisa uphawu lokuthengisa olufanayo lwe-'Retina' ye-27-by-5120-pixel 2880-intshi ye-iMac njengoko benzayo nge-iPhone 4 edumileyo, eyayinomboniso we-3,5-intshi kunye nephaneli ye-960-by-480-pixel. Kuzo zombini ezi meko, ezi mveliso zimbini zinescreen esixinene ngokuphindwe kane njengabanduleli bazo.
Kutheni i-4K inyuswa kangaka kwaye ingeyiyo i-HiDPI?
Ngelishwa, ngenxa yezizathu urhwebo. Kuninzi okuthethwayo kwi-Intanethi ukuba i-Apple ihlala izama ukusithengisela ibhayisekile ngetekhnoloji yayo, kodwa inyani yeyokuba bahamba ngqo xa besithengisela iRetina Display. Ukuthatha imeko yangaphambili ye-13-intshi yelaptop njengomzekelo, ngaphezulu komenzi omnye ukhetha ukuthengisa isikrini nge isisombululo esingalunganga (okt ayihambelani ne-HiDPI) okoko nje isitsho kwileyibhile ukuba kunjalo 4K. Yiyo loo nto sithe ekuqaleni ukuba i-HiDPI ibaluleke ngakumbi kune-4K, kuba akunamsebenzi ukuba nescreen esixineneyo ukuba uya isikali esingalunganga Okanye kuya kufuneka ukrobe ukuze ujonge kakuhle iifayile ezikwidesktop yakho.
