Elinye lamaqhekeza olwazi esihlala silinika xa dwelisa iinkcukacha zethebhulethi bubuninzi bepixel, obulinganiswa ngeepixels nge-intshi nganye (dpi okanye ppi ye-akhronimi ngesiNgesi). Kodwa ayinguye wonke umntu oyaziyo ukuba yintoni kwaye ingakumbi ukuba iwuchaphazela njani umgangatho womfanekiso onokuthi ipaneli ithile ibonelele. Sicacisa ezinye iikhonsepthi ezingundoqo ukuze uzithathele ingqalelo kwaye sibonisa ulwahlulo kunye neetafile ngoku ezinobuninzi bepixel obukhulu.
Yintoni pixel density?
Ungayifumana inkcazo naphi na. Ubuninzi bePixel ngumlinganiselo obala inani leepixels ngaphakathi kwendawo enikiweyo, kule meko i-intshi enye. Inkulu sigqibo, ikhusi elilinganayo ubungakanani ziya kuba noxinano oluphezulu kuba inani elikhulu kufuneka lingene kwindawo enye, oko kukuthi, libe lincinci kwaye ke, kunzima kakhulu ukuliqonda kwindawo ethile. umgama. Yile nto kanye yokugqibela edla ngokungahoywa kolunye uhlalutyo.
Ngaba kukho umda kwiliso lomntu?
Ngokucacileyo ewe. Iliso lomntu njengalo naliphi na elinye ilungu lomzimba wethu lilinganiselwe. Zingaphi iipixels nge-intshi nganye esizibonayo? Kwiminyaka embalwa edlulileyo, uSteve Jobs wathi lo mqobo ubekwe kwindawo I-300 dpi kumgama we-30 cm, kwaye wakwenza esazi ezinye iingxelo zenzululwazi. Ngaba iyavakala ke into yokuba benze izikrini ezingaphezu kwe-400 dpi? Ewe kwaye hayi. Ukusetyenziswa okuqhelekileyo, asiyi kuphawula umehluko omkhulu, kuba asiqhelekanga ukusondeza isixhobo esingaphezu kwama-30 cm, kodwa kunokubakho iimeko apho lo mgangatho uvumela umgangatho ophezulu womfanekiso.
Umgangatho ophezulu we-pixel woxinaniso lwethebhulethi
- IHuawei MediaPad X1: Indawo yesithandathu yile modeli yeHuawei, evezwe ekuqaleni konyaka kunye nesikrini se-7-intshi kunye nesisombululo esipheleleyo seHD (1.920 x 1.200 pixels) efikelela kubuninzi be-323 dpi.
- i-xiaomi mipad: U-Xiaomi ungene kwimarike kwaye wenze njalo ngomnyango wangaphambili, kunye nesixhobo esivelele kumacandelo amaninzi. Phakathi kwabo isikrini se-7,9-intshi kunye nesisombululo se-2.048 x 1.536 pixels esisishiya sinobuninzi be-324 dpi.
- Apple iPad mini 3: sinokuphinda sibeke i-predecessor yayo, i-iPad mini 2. Ubungakanani obufanayo besikrini njenge-Xiaomi MiTab, isisombululo esifanayo kwaye ngoko ke, ukuxinana okufanayo: 324 dpi. I-Apple ibigcina le ingxinano kangangexesha elithile ngenxa yezizathu ebesikuxelele zona ngaphambili.
- Umlilo weAmazon HDX 8.9: singene eqongeni. Isigebenga se-e-commerce siqaqambise lo mgangatho xa sibonisa ithebhulethi entsha 2560 x 1600 pixels kwii-intshi ze-8,9 ezikhokelela kwi-339 dpi.
- Indawo yaseDell 8 7000: Eyaziwa ngokuba yeyona tablet ibhityileyo ehlabathini (6 millimeters), ikwanayo ebalaseleyo 8,4-intshi OLED screen kunye 2.560 x 1.600 pixel isisombululo 359 dpi.
- I-Samsung Galaxy Tab S 8.4: kwaye inombolo enye yesona sikrini silungileyo kwimarike ngokweengcali. I-teknoloji ye-SuperAMOLED, i-intshi ye-8,4 ngobukhulu kunye ne-2.560 x 1.600 isisombululo se-pixel esisinika uxinano olufana ne-Venue 8 7000: 359 dpi.
