Ngale kwesinqumo: izici zesikrini esihle kuthebhulethi

Ngaphandle uma siyayazi imigomo, kwesinye isikhathi kungaba nzima ukuzulazula kunqwaba yezibalo nama-akhronimi siphonswe kithi ngamashidi okusebenzela. Ukucaciswa kobuchwepheshe amaphilisi futhi, okubi nakakhulu, ngokuvamile awanele ukusinika umbono wokuthi kuhle noma kubi kangakanani ikhwalithi yesithombe kwedivayisi noma ukufaneleka kwayo isikrini Okwethu imikhuba. Ngakho-ke, ukukusiza ukuthi ukhethe ithebhulethi engakushiya unelisekile, namuhla sibuyekeza zonke izici lokho kungaba nomthelela wakho isipiliyoni somsebenzisi.

Naphezu kwesikhalo esingangabazeki sokuthi idizayini ihlala isebenza kithi lapho sikhetha amathebulethi (futhi okufanayo kwenzeka kuma-smartphone) kanye nokubaluleka ukusebenza kwawo okuba nakho kokuhlangenwe nakho komsebenzisi, kuvame kakhulu ukuthi isikrini igcina isingesinye sezici ezinqumayo ekugcineni futhi kwenza umqondo omkhulu ukuthi lokhu kunjalo, sicabanga ngesisindo esinqumayo esingasisebenzisa ekujabuleleni kwethu lapho siphequlula, sifunda, sidlala noma sibuka amafilimu. bona. Eqinisweni, ingesinye sezigaba lapho umehluko phakathi kwamaphilisi ayisisekelo naphakathi nendawo kanye namaphilisi aphezulu waziswa kakhulu.

Kubuye kube nengqondo ukuthi into yokuqala esiyibukayo lapho sihlola isikrini isinqumo: ngokungangabazeki kuyinkinga emaphakathi, kulula ukuyihumusha idatha futhi ihlala ikhona kumashidi ezicaciso zobuchwepheshe, ngakho kulula ukuyifinyelela. Iqiniso, nokho, ukuthi njengoba libaluleke kangakanani, ngeke kube ukuphela kwento esiyibukayo. Ngisho nalapho ukwazisa nencazelo yini esingayilindela ku-a isikrini, kuhle ukuqaphela ukuthi kunenye idatha okufanele uyicabangele, njengoba ingeyakho nje usayizi. Okuyizi izici, ke, yesikrini esihle?

Ukulungiswa kubalulekile, kodwa kuze kufike ephuzwini

Siqala ngokugcizelela ekuboneni ukubaluleka esijwayele ukunamathisela kukho isinqumo Akulungile neze: kufanele kukhunjulwe ukuthi ukulungiswa okuhle ngeke kusivumele kuphela ukuthi sibone ividiyo nezithombe eziphakeme kakhulu. detalle, kodwa kuyisici esithakazelisa kakhulu futhi ukuzulazula nokufunda, kusukela ezingeni le nencazelo ikhombisa okuningi ngemibhalo emincane. Okubalulekile ukuthi ungakucabangeli ngokweqile, njengoba iphuzu lapho usizo lokwenyuka kwesixazululo luqala ukwehla ngokuphawulekayo, ngenxa nje yokuthi iso lomuntu likuthola kunzima kakhulu ukukuqonda.

Ukulungiswa kanye nokuminyana kwephikseli

Umbuzo wesibili okufanele siwukhumbule lapho sikhuluma ngawo isinqumo, ukuthi lokhu akukwazi ukucatshangelwa ngokuhlukana, kodwa kubalulekile ukuyibeka njalo maqondana ne usayizi kwesikrini, into enethonya kakhulu ibanga kusukela emehlweni ethu lapho sizobeka idivayisi futhi ku usizi lwe-pixel okungukuthi, kalula, inani lamaphikseli iyintshi ngayinye yesikrini, idatha efaneleke kakhulu yokulinganisa ukuthi incazelo yesikrini yanele noma cha. Ngokusho kongoti, I-200 PPI (amaphikseli iyintshi ngayinye noma amaphikseli nge-intshi ngayinye) angaphezu kokwanele idivayisi ephathwayo, futhi yisibalo esifezwa ngesikrini se-HD kuthebhulethi engu-7-intshi (I-216 PPI) kanye nesikrini esigcwele se-HD ku-10.1-intshi (I-224 PPI).

4:3 noma 16:9?

Esinye isici okufanele sicabange ngaso lapho sikhetha amaphilisi ukuthi yisiphi isici esisikhethayo. Kuze kube kudala, kwakuyisinqumo esenziwe ngempela, ukuthi uyafuna noma cha, lapho ukhetha uhlelo lokusebenza, kusukela amaphilisi. Android cishe zazihlale zinefomethi 16:9 futhi i iPad ifomethi 4:3. Okwamanje asikakwazi ukukhetha ukuba nethebhulethi ye-iOS enefomethi engu-16: 9, kodwa okungenani sinawo amathebulethi e-Android anefomethi engu-4: 3 esinawo, empeleni, ayanda nangaphezulu. Uyini umehluko phakathi kokukodwa nokunye? Kalula nje ukuthi ifomethi 16:9 side kakhulu futhi ivumelana kangcono ne- ukudlala ividiyo, okusivumela ukuthi sisebenzise ngokunenzuzo cishe sonke isikrini, kuyilapho i 4:3 ilungiselelwe ukufunda futhi "intshontsha" ingxenye enhle yendawo yethu lapho sifaka imuvi, ngokuvela imigqa emibili emnyama ebanzi phezulu nangaphansi.

TFT, IPS kanye ne-AMOLED

Olunye ucezu lolwazi esingabonisana nalo kunoma yiliphi ishidi lokucaciswa kwezobuchwepheshe futhi elingathonya isinqumo sethu uhlobo lwesikrini ngokwaso, futhi sizothola u-3, ngokuyisisekelo, nakuba u-2 wawo eyizinhlobo ezincane zesinye: i I-TFT futhi i I-IPS, okuyizinto ezimbili ezihlukene zezikrini I-LCD, kanye I-AMOLED. Umehluko phakathi kwama-TFT nama-iPSs umbuzo wekhwalithi ngokuyisisekelo: Ama-IPS masha, anama-engeli wokubuka angcono, adla kancane futhi ubudala bungcono. Cishe zonke izikrini ze-LCD esizithola seziyi-IPS, ngisho naphakathi kwamaphilisi ashibhe kakhulu, kodwa asekhona ambalwa anezikrini ze-TFT. Umehluko phakathi kwezikrini ze-AMOLED ne-LCD, ngakolunye uhlangothi, uhlobene neqiniso lokuthi zinokuqhathanisa okungcono nama-engeli wokubuka, zisebenzisa kancane futhi zincane futhi zilula. Nokho, akuzona zonke izinzuzo, njengoba ngokwesiko bethambekele ekuchithweni kwe-supersaturation. Amathebulethi kuphela anezikrini ze-AMOLED ezithengiswayo njengamanje, noma ngabe yikuphi, yila I-Galaxy Tab S futhi kufanele uqaphele Samsung okuye kwayiqeda ngempela leyo nkinga.

Hlola ama-engeli wokubuka

Kumashidi ezicaciso zobuchwepheshe ngokuvamile ngeke sibe nedatha eqinisekisayo mayelana nalokhu ukubuka ama-engeli, kodwa kuyinto esingazihlola kalula uma sinethuba lokuthola izandla zethu kudivayisi ngaphambi kokuyithenga. Kumane kuyindaba yokuhlola ukuthi ikhwalithi yesithombe igcinwa kangakanani njengoba sihambisa ithebhulethi ukuze siyeke ukuyibuka ngokuphelele ngaphambili. Kungase kungabalulekile njengezinye izinkinga, kodwa uma uthanda ukubuka uchungechunge noma amafilimu kuthebhulethi enkampanini noma uma uvele ulale kusofa noma embhedeni ezindaweni ezingavamile, uzokwazisa ukuthi inama-engeli amahle okubuka. , Futhi kuyinto ngezinye izikhathi enganakwa kumathebulethi ekhwalithi ephansi.

Naka ukukhanya, okuphezulu kanye nobuncane

Olunye udaba okulula kakhulu ukulubukela phansi amazinga we kukhanye yethebhulethi, lapho ibalulekile uma sihlela ukuyisebenzisa ezimeni ezahlukene ze ukukhanya, okuyinto cishe esizoyenza. Ngakolunye uhlangothi, ukuthi ukukhanya okukhulu iphezulu ngangokunokwenzeka izosisiza kakhulu ukuthi sibone isikrini kahle ngaphandle (kanye nezinga lokucabanga), kuyilapho a ubuncane okuphansi ngangokunokwenzeka kuzokwenza kube mnandi kakhulu ukuzulazula noma ukufunda ezindaweni kumnyama, embhedeni ebusuku, isibonelo. Njengomthetho ojwayelekile, izikrini ze-LCD zinama-maximus aphezulu kanye nobuncane obuncane be-AMOLED, kodwa lena akuyona idatha evame ukutholakala kumakhasi ezicaciso zobuchwepheshe futhi ngisho nasekuqhathanisweni kwevidiyo ayiboniswa kuzo zonke izimo. Noma kunjalo, kungakhathaliseki ukuthi yini ongazibonela yona ngethebhulethi esandleni, ungahlala ubheka ukuhlolwa kokuhlaziywa kochwepheshe, njengalabo Bonisa iMate, esivame ukunanela lapho ithebhulethi enkulu yethulwa.

Izindleko mayelana nokusetshenziswa

Futhi akulimazi, ukuqeda, cabangela ukuthi ukhetho esikrinini luzoba nomunye uzakwabo ngaphezu kwentengo, futhi lokho ukusetshenziswa. Impela, kunezici eziningi ezinganxephezela isikrini esifuna kakhulu, njengebhethri elinamandla amakhulu noma izinhlelo ezihlukile zokuthuthukisa abakhiqizi abangazisebenzisa, kodwa kuzohlala kulula ukuzuza ukuzimela okwanelisayo ngesikrini esinesinqumo esiphansi. Izikrini ze-AMOLED ngokujwayelekile, kanye nalezo ze I-Galaxy Tab S ikakhulukazi, banokusetshenziswa okuphansi, nakuba benephuzu elibuthakathaka (uma siqala ukucwenga okuningi) okuwumbala omhlophe, ukuze uma sihlela ukusebenzisa ithebhulethi yethu ikakhulukazi ekufundeni, ukulondoloza cishe ngeke kube njalo. okubonakalayo.

Cabanga ukuthi sizoyisebenzisa kanjani futhi kangakanani ngempela ithebhulethi yethu

Njengoba ubona, ukubaluleka kwesici ngasinye kungahluka kakhulu kuye ngohlobo lokusebenzisa esizokunikeza ithebhulethi yethu, ngakho-ke kubaluleke kakhulu ukuthi sime sicabange ngokweqiniso ukuthi sizoyisebenzisa kanjani futhi kangakanani. Kunjalo, uma singenayo imikhawulo yesabelomali, singakucebisa kuphela ukuthi uthole okukodwa I-Galaxy Tab S (noma ulinde kancane ukuthi abalandelayo baqale) noma amanye amaphilisi aphezulu anezilinganiso ezingcono (iPad Air, Surface Pro 3…), Kodwa uma kukhona ukulinganiselwa kufanele sicabange ukuthi kukhona ukuzidela okungase kusilimaze kancane kunabanye, futhi ukulahlekelwa okuthile ekuxazululeni kungase kungabi umonakalo omkhulu kakhulu.
