Ngaphandle kwesisombululo: iimpawu zesikrini esilungileyo kwithebhulethi

Ngaphandle kokuba siqhelene nemigaqo, ngamanye amaxesha kunokuba nzima ukuzulazula kubuninzi bamanani kunye nee-akhronimi ezijulwe kuthi ngamaxwebhu okusebenzela. Ukucaciswa kobugcisa yamacwecwe kwaye, eyona nto imbi ngakumbi, zihlala zingonelanga ukusinika umbono wokuba zilungile okanye zimbi kangakanani umgangatho womfanekiso yesixhobo okanye ukufaneleka kwaso isikrini Yeyethu imikhwa. Ke ngoko, ukukunceda ukhethe ithebhulethi enokukushiya wanelisekile, namhlanje sijonga yonke into izinto oko kunokuchaphazela yakho amava omsebenzisi.

Ngaphandle kwesibheno esingathandabuzekiyo sokuba uyilo luhlala lusebenza kuthi xa ukhetha iitafile (kwaye kuyenzeka okufanayo ngee-smartphones) kunye nokubaluleka kokusebenza kwazo kumava omsebenzisi, kuqhelekile ukuba isikrini iphelela ekubeni ibe yenye yezinto ezithatha isigqibo ekugqibeleni kwaye yenza ingqiqo enkulu ukuba oku kunjalo, sicinga malunga nobunzima obunokubusebenzisa kulonwabo lwethu xa sikhangela, sifunda, sidlala okanye sibukele iimuvi kunye. bona. Enyanisweni, elinye lamacandelo apho umahluko phakathi kweepilisi ezisisiseko kunye ne-middle-range kunye neepilisi eziphezulu zixabiswa kakhulu.

Kwakhona kwenza ingqiqo eninzi into yokuqala esiyijongayo xa sivavanya isikrini sigqibo: ngokungathandabuzekiyo ngumba ophakathi, kulula ukutolika idatha kwaye ihlala ikhona kumaphepha enkcazo yobugcisa, ngoko kulula ukufikelela kuyo. Inyaniso, nangona kunjalo, yeyokuba, nangona ibaluleke kangakanani, ayinakuba kuphela kwento esigxininisa kuyo. Naxa uxabisa i inkcazo yintoni esinokuyilindela kwi-a isikrini, kuhle ukuba uqaphele ukuba kukho enye idatha ekufuneka ithathelwe ingqalelo, njengoko iyinto yakho nje ubungakanani. Zeziphi ezi iimpawu, ke, yesikrini esilungileyo?

Isisombululo sibalulekile, kodwa ukuya kwinqanaba

Siqala ngokugxininisa ekuqondeni ukuba ukubaluleka esiqhele ukuncamathela kubo sigqibo Akunjalo konke konke: kufuneka kukhunjulwe ukuba isisombululo esihle asiyi kusivumela kuphela ukuba sibone ividiyo kunye neefoto ezinomgangatho ophezulu. iinkcukacha, kodwa luphawu olunika umdla kakhulu kwakhona ukuhamba kunye nokufunda, ukusukela kwinqanaba inkcazo ibonisa kakhulu ngoshicilelo oluncinci. Eyona nto ibalulekileyo kukuba ungayibaxi, kuba inqaku apho uncedo lokunyuka kwesisombululo luqala ukuhla ngokuphawulekayo, ngenxa yokuba iliso lomntu lifumana kunzima ukuwaxabisa.

Isisombululo kunye nobuninzi be-pixel

Umbuzo wesibini emawuwukhumbule xa sithetha ngawo sigqibo, kukuba le nto ayinakuqwalaselwa yedwa, kodwa kubalulekile ukuyibeka rhoqo ngokumalunga ne ubungakanani kwesikrini, into enefuthe kakhulu kwi umgama ukusuka kwamehlo ethu apho siza kubeka isixhobo kunye nakwi uxinzelelo lwe-pixel elinani nje leepixels nge-intshi nganye yekhusi, eyona datha ifanelekileyo yokulinganisa ukuba inkcazo yekhusi yanele na okanye hayi. Ngokutsho kweengcali, 200 PPI (pixels nge-intshi nganye okanye iipixels nge-intshi nganye) zingaphezulu kokwaneleyo kwisixhobo esiphathwayo, kwaye ngumfanekiso ophunyezwa ngescreen seHD kwithebhulethi eyi-intshi eyi-7 (216 PPIkunye nescreen esigcweleyo seHD kwi10.1-intshi (224 PPI).

4:3 okanye 16:9?

Enye inkalo ekufuneka sicinge ngayo xa sikhetha iipilisi kukuba yeyiphi iaspect ratio esiyikhethayo. Kude kube kudala, yayisisigqibo esenziwe ngokwenene, ukuba uyafuna na okanye awufuni, xa ukhetha inkqubo yokusebenza, ukusukela iitafile. Android zaziphantse zahlala zinefomathi 16:9 kunye iPad ifomathi 4:3. Okwangoku asikwazi ukukhetha ukuba nethebhulethi ye-iOS enefomathi ye-16: 9, kodwa ubuncinci sinazo iitafile ze-Android ezinefomathi ye-4: 3 esinayo, enyanisweni, ngakumbi nangaphezulu. Uthini umahluko phakathi kwenye nenye? Ngokulula ukuba ifomathi 16:9 inde kwaye iqhelanisa ngcono ne Ukudlala ividiyo kwakhona, esivumela ukuba sithathe ithuba malunga nescreen sonke, ngelixa i 4:3 yenzelwe u kufunda kwaye "iba" inxalenye elungileyo yendawo yethu xa sibeka imuvi, ngokuvela imivimbo emibini ebanzi emnyama phezulu nasezantsi.

TFT, IPS kunye ne-AMOLED

Olunye ulwazi esinokubonisana nalo kulo naliphi na iphepha lenkcazo yobugcisa kwaye elinokuthi libe nefuthe kwisigqibo sethu luhlobo lweskrini ngokwalo, kwaye siza kufumana i-3, ngokusisiseko, nangona i-2 yazo i-subtypes enye: i Umbonakaliso kunye IPS, eziziintlobo ezimbini zezikrini LCD, kwaye i AMOLED. Umahluko phakathi kwe-TFTs kunye nee-iPSs ngumbuzo womgangatho: ii-IPS zintsha, zineengile zokujonga ezingcono, zidla kancinci kwaye zineminyaka engcono. Phantse zonke izikrini ze-LCD esizifumanayo sele sele ziyi-IPS, naphakathi kweepilisi ezinexabiso eliphantsi, kodwa kusekho ezimbalwa ezinezikrini ze-TFT. Umahluko phakathi kwe-AMOLED kunye ne-LCD izikrini, okwangoku, zinento yokwenza nokuba zinee-engile ezingcono kunye nokubukela, zidla ngaphantsi kwaye zincinci kwaye zilula. Noko ke, asizizo zonke iingenelo, ekubeni ngokwesithethe ziye zatyekela ekugqityweni ngamandla. Ekuphela kweetafile ezinezikrini ze-AMOLED ezithengiswayo ngoku, kuyo nayiphi na imeko, zezi Galaxy Tab S kwaye kufuneka uqaphele Samsung nto leyo eye yaphelisa loo ngxaki.

Jonga ii-engile zokujonga

Kumaphepha enkcazo yobugcisa asiyi kuba nayo nayiphi na idatha eqinisekileyo malunga ne ukujonga ii-angles, kodwa yinto esinokuzivavanya ngokulula ukuba sinethuba lokufumana izandla zethu kwisixhobo ngaphambi kokuba sisithenge. Kungumbandela nje wokujonga ukuba umgangatho womfanekiso ugcinwa kangakanani njengoko sihambisa ithebhulethi ukuze siyeke ukuyijonga ngokupheleleyo ngaphambili. Isenokungabalulekanga njengeminye imiba, kodwa ukuba uyathanda ukubukela uthotho okanye iimuvi kwithebhulethi kwinkampani okanye ukuba uphela ulele kwisofa okanye ebhedini kwindawo engaqhelekanga, uya kuyixabisa into yokuba ineengile zokubukela ezintle. , Kwaye yinto enokuthi ngamanye amaxesha ingahoywa kwiipilisi zomgangatho ophantsi.

Nika ingqalelo ekukhanyeni, ubuninzi kunye nobuncinci

Omnye umba ekulula kakhulu ukuwujongela phantsi ngamanqanaba khanye yethebhulethi, xa ziyimfuneko ukuba siceba ukuyisebenzisa kwiimeko ezahlukeneyo ze ukukhanya, nto leyo mhlawumbi siya kuyenza. Kwelinye icala, ukuba i Ukukhanya okuphezulu iphezulu kakhulu iya kusinceda kakhulu ukuba sibone isikrini kakuhle ngaphandle (kunye nenqanaba le-reflexes), ngelixa a ubuncinci okuphantsi kangangoko kuyakwenza ukuba kube mnandi ngakumbi ukuzulazula okanye ukufunda kwimo engqongileyo mnyama, ebhedini ebusuku, umzekelo. Njengomgaqo jikelele, izikrini ze-LCD zinee-maximum eziphezulu kunye nee-AMOLED ezisezantsi, kodwa ayisiyiyo idatha ehlala ifumaneka kumaphepha enkcazo yobugcisa kwaye akukho nakuthelekiso lwevidiyo luboniswa kuzo zonke iimeko. Nangona kunjalo, kungakhathaliseki ukuba unokuzibonela ntoni ngethebhulethi esandleni, unokuhlala ujonga uphononongo lohlalutyo lweengcali, ezifana nezo Bonisa iMate, esihlala siphindaphinda xa ithebhulethi enkulu isungulwa.

Iindleko ngokwemiqathango yokusetyenziswa

Kwakhona akwenzi buhlungu, ukugqiba, kuthathele ingqalelo ukuba unyulo kwisikrini luya kuba nelinye iqabane ukongeza kwixabiso, kwaye oko benzisa. Ewe kunjalo, zininzi izinto ezinokuhlawulela isikrini esifunwayo, esinje ngebhetri enomthamo ophezulu okanye iinkqubo ezahlukeneyo zokuphucula ezinokuthi abavelisi baphumeze, kodwa kuya kuhlala kulula ukufezekisa ukuzimela okwanelisayo ngescreen esinesisombululo esisezantsi. Izikrini ze-AMOLED ngokubanzi, kunye nezo ze Galaxy Tab S ngokukodwa, banokusebenzisa okuphantsi, nangona banendawo ebuthathaka (ukuba siqala ukucokisa kakhulu) ngumbala omhlophe, ukuze ukuba siceba ukusebenzisa ithebhulethi yethu ngokukodwa ekufundeni, ukugcinwa mhlawumbi akuyi kuba njalo. ebonakalayo.

Cinga malunga nokuba siza kuyisebenzisa kangakanani kwaye ingakanani ithebhulethi yethu

Njengoko ubona, ukubaluleka kwenkalo nganye kunokwahluka kakhulu kuxhomekeke kuhlobo losetyenziso esiza kulunika ithebhulethi yethu, ngoko ke kubaluleke kakhulu ukuba siyeke ukucinga ngokwenyani ukuba siza kuyisebenzisa njani kwaye kangakanani. Ewe, ukuba asinayo imiqobo yohlahlo lwabiwo-mali, sinokukucebisa kuphela ukuba ufumane enye ye Galaxy Tab S (okanye ulinde kancinane ukuba abalandela emva kwabo baqale) okanye ezinye iipilisi eziphezulu ezinomlinganiselo ongcono (iPad Air, Surface Pro 3...), kodwa ukuba kukho imida kufuneka sicinge ukuba kukho imibingelelo enokusilimaza ngaphantsi kunabanye, kwaye ukulahlekelwa yinto kwisisombululo kungabi ngumonakalo omkhulu.
