Kana tikataura newe nezvazvo HiDPIHaiwa Jehovha, imi hamuzivi zvatiri kutaura nezvazvo, asi kana tikakurevai 'Retina kuratidza', unogona kunge uchitoziva kuti pfuti dziri kuenda kupi. Kunyange munhu wese achiziva nezveApple's high-density display tekinoroji, HiDPI inyaya isinganzwisisike nevanhu vazhinji nekuti ruzivo rwatinowana paInternet runovhiringa. Mune ino positi isu tichagadzirisa kusahadzika kuripo kwakatenderedza iyi nomenclature iri kunetseka kuve chiyero chitsva.
Chii chinorehwa neHiDPI?
HiDPI inomirira kuti "High Dots Per Inch", iyo muSpanish inoturikira se "high pixel density per inch". Iro zita rinotengeswa tekinoroji iyi rinosiyana zvichienderana nemugadziri, ne 'Retina' iri iyo vhezheni yakagamuchira yakanyanya hype nekuda kwekuve nekambani yakaita seApple kumashure kwayo.
Muchidimbu, HiDPI inouya kuzotsanangura kuti kune a kuwirirana kwakakwana pakati pepixel yemuviri yechidzitiro uye pixel chaiyo. Usanetseke kana zvese izvi zvichirira chiChinese kwauri nekuti vazhinji vanotarisa uye vagadziri vemakomputa havasati vanzwisisa pfungwa iyi. Nguva diki gare gare tichatsanangura izvo HiDPI inosanganisirwa nemienzaniso yakati wandei iyo iwe uchakwanisa kunzwisisa iyi pfungwa nekujeka kukuru.
HiDPI yakakosha kupfuura 4K
Musika uzere nezvigadzirwa zvinotengeswa ne4K resolution. Nekudaro, iyo indasitiri haina kumbobvira yaita basa rayo rechikoro munzvimbo iyi. 4K haisi chiyero, kunyange tichitenda kudaro, uye haina nhamba chaiyo yemapikisi akapihwa kwairi kureba kana kureba, chimwe chinhu chakaitika mumiyero yakapfuura (480p, 720p uye 1080p).
Saka… Chii chinonzi 4K? Tsanangudzo yaro haireve saizi yescreen kana resolution, asi kune a image format iyo inenge 4.000 pixels yakachinjika. Zviripachena, tsananguro iyi inoburitsa zvakawanda kuvhiringidzika. Semuenzaniso, terevhizheni ye4K ndiyo ine 3.840 by 2.160 pixel matrix ine 16:9 aspect ratio. Uye 4K digital cinema sikirini ndeye 4.096 ne2.160 pixels, ine 17:9 chimiro chechiyero.
density ndiyo nyaya
Isu tave kunzwisisa kuti iyo chaiyo tsananguro ye4K inosanganisira huwandu hwezvigadziriso zvakatenderedza 4 miriyoni pixels muhuwandu. Ngatiti iwe unoenda kuchitoro chako chaunovimba uye wotenga pani ye3840 ne2160 pixels. Ndiyo 4K here? Hongu. Chidzitiro cheHiDPI here? Izvo zvinoenderana nehukuru hwepaneru. handei nevashoma mienzaniso kuti uzvione zvakajeka:
- Kana uri kutaura nezve a komputa monitor uye ane zvimwe 32 inches, ingangove yakagadzirwa kuti ionekwe kubva kure nemamita. Mumwe nomumwe pixel yemuviri pachiratidziro chichaenderana nea virtual pixel ye sisitimu yekushandisa. Saizi yechidzitiro ichakubvumidza iwe kuve nemazana emifananidzo pane desktop yako. Iwe unozogona kuve neakawanda maapplication akavhurika anoenderana uye hauzove nematambudziko ekuverenga mameseji mune chero yeaya mahwindo nekuti iyo font ichave inonyoreka zvachose. Uye kwete, tinenge tisiri kutaura nezve HiDPI skrini, asi yeLoDPI, sezvo chiyero chayo chiri 1x.
- Kana sarudzo yakataurwa iri mu a 15 padiki Laptop, tingava nedambudziko chairo kana chiyero chaiswa ku1x. Hapana chawaigona kuverenga nekuti pakanga pasina kuwirirana pakati skrini density uye system interface. Zvichadaro kana isu tichifanira activate the pixel kaviri, kureva, HiDPI. Izvi zvichaita kuti pixel yega yega pachiratidziro yedu ive ina (imwe ichipetwa kaviri paX axis yechidzitiro uye imwe yakapetwa kaviri paY axis). Ikozvino, sikweya yega yega yemapikisi emuviri pascreen yedu ichave yakaenzana nepixel chaiyo ye1920 ne1080 resolution, inova sarudzo yatinoziva. Nekuita nzira iyi, hapazovi nematambudziko ekurodza. Chikero chinofanirwa kukwana zvakakwana, zvinyorwa zvinofanirwa kujeka uye hapafanirwe kuve nemhando ipi neipi yakasviba icon kana menyu pachiratidziro chedu.
- Uye kana tikataura nezve skrini ye a 13 padiki Laptop? Pa1x tichava nedambudziko rakakura kupfuura neiyo 15-inch laptop. UYE kana tikapeta mapixels (kureva kuti kana tikawana mapixels mana papixel yega yega) ese icharamba ichiita sediki. Saka chii chinoitika kana tikatora 3 ne3 pixel matrix? Hatizogadzirise dambudziko zvakare, sezvo tikashandura pixel yega yega kuita mapfumbamwe, tinenge tatoenda kure. Muzviitiko izvi, tichafanirwa kusarudza imwe sarudzo yemuviri. Kune skrini ye 13 inches, Full HD resolution haina kunaka. Vagadziri vakakomba nezvezvigadzirwa zvavo vakamboshandisa matrix ye 1.600 ne900 pixels. Saka kugadzira sikero chaiyo, 13-inch laptop inoda kuve nekugadzirisa padyo ne4K inofanira kuva nepanera iyo iri 3.200 ne1.800 pixels. Zvinogona kuita kunge zvakapusa (zvingori mazana mashoma mapixels akaparadzana pane imwe neimwe axis), asi kushandiswa kwayo kuchave kwakasiyana kwazvo. Zvinhu zviri pachiratidziro zvichava nechiyero chakarurama, kusiyana ne3840 ne2160 pixel matrix, iyo isingazotaridzi zvakanaka zvachose. Ah, uye kana wanga uchinetseka, 13-inch skrini ine 3.200-by-1.800-pixel pani haikodzere se4K. Asi hongu iHiDPI. Kuda kuziva, handiti?
Chii chinoitika kana skrini kana system isingatsigire HiDPI?
Kupfuura zvatachangobva kutsanangura mundima yapfuura, pane rimwe dambudziko rakawedzerwa patinotaura nezvaro zviratidzo zvisingatsigiri HiDPI, iyo nenzira, ndiyo yakawanda yakawanda yezvikwangwani zvatinowana pamusika. Kurerutsa muenzaniso, fungidzira kuti tine 15-inch laptop pamberi pedu. Isu tinoziva kuti 1920 ne108o igadziriso chaiyo yechidzitiro chezviyero izvi. Chii chinoitika kana pachinzvimbo chekushandisa HiDPI skrini (kureva iyo 3840 by 2160 pixels mumuenzaniso uri pamusoro) tikashandisa ratidza nechiyero che 1,5x pachinzvimbo che 2x? Zvakanaka, kuti iyo interface yese itore nzvimbo imwechete seyakazara HD, sisitimu yacho yaizofanirwa kuyerwa ka1,5.
Asi hechino chimwe chinhu chisingabatanidzi. Wazviona here? Hazvigoneki kuzvigadzirisa. Isu tiri kuenda ku zoom mukati pachiratidziro uye isu tichaona mapikseli akasiyana. Kana pasina 4:1, 9:1, kana 16:1 mepu, pixel yega yega inofanira ikozvino. muviri tora pixel nehafu. uye midhiya pixels havapo.
Saka system yacho inoita sei? Offset uchishandisa iyo yakakurumbira aliasing, iyo isingaregi kuva a bvisa firita iyo inodzima pixel kuti itevedzere iyo hafu inoshaikwa poindi. Mhedzisiro injodzi yakazara uye kana yapihwa mumavara, inoratidza kuti denser skrini haisi nani. Pirelli aiwanzotaura kuti "Simba risina simba harina maturo", uye uyu muenzaniso wakajeka wekuti vagadziri vanofanira kutanga kuisa mabhatiri avo pamwe chete uye kutanga dosing simba iroro. HiDPI haisi kushambadzira, asi chisimbiso chinovimbisa kuti kugadziriswa kwemonitori hakuna kusarudzwa zvisina kufanira.
Ndeupi musiyano uripo pakati peHiDPI neRetina Display?
Nechinangwa kutaura, hapana. 'Retina Display' haisi chimwe chinhu kunze kwekutengesa nomenclature iyo yakanyoreswa Apple kureva zviratidziro zvako zvinoenderana neHiDPI. Apple painotitengesera chigadzirwa chine 'Retina Display', iyo apple brand inoreva chokwadi chekuti kugadziriswa kwezvigadzirwa zvayo kwakagadzirwa kuti. hapana nyaya dzechiyero Hapana ma interfaces asina kujeka. Ivo vanoshandisa iyo imwe chete 'Retina' trademark ye27-by-5120-pixel 2880-inch iMac sezvavakaita neyakakurumbira iPhone 4, iyo yaive ne3,5-inch kuratidza uye 960-by-480-pixel pani. Muzviitiko zvese izvi, zvigadzirwa zviviri izvi zvine chidzitiro chakapetwa kana kuti chakakora sevakatangira.
Sei 4K ichinyungudika uye isiri HiDPI?
Zvinosuruvarisa, nokuda kwezvikonzero Marketing. Zvakawanda zvinotaurwa padandemutande kuti Apple inogara ichiedza kutitengesera bhasikoro nehunyanzvi hwayo, asi chokwadi ndechekuti ivo vanoenda kumberi apo vanotitengesera Retina Display. Tichitora iyo yapfuura kesi ye13-inch laptop semuenzaniso, vanopfuura mumwe mugadziri vanofarira kutengesa skrini ine chisarudzo chisina kururama (kureva kuti haisi HiDPI inoenderana) chero ichitaura pane iyo label kuti ndizvo 4K. Ndosaka takataura pakutanga kuti HiDPI yakakosha kupfuura 4K, nekuti hazvibatsiri kuve nedenser skrini kana uchizove ne chikero chisina kunaka Kana kuti iwe uchafanirwa squint kuti utarise zvakanaka mafaera ari padesktop yako.
