Aadan Koos Waxaan inta badan la kulmaa PPI-da ee ku saabsan bandhigyada taleefanka gacanta. Waa unug lagu cabbiro cufnaanta dhibcaha sawirka, ama pixels, marka ay muujinayso inta ku habboon hal inch. Oo haddii aad u maleyneyso in taleefannada casriga ah ee ugu dambeeyay ay si joogto ah u kordhinayaan lambarkan, gabi ahaanba run maaha. Hoggaamiyuhu waa aaladda laga bilaabo 2017.
Apple ayaa soo bandhigtay afar ka mid ah iPhone 13 sanadkan. 13 mini model ayaa leh 476 PPI, iPhone 13 oo ay weheliso iPhone 13 Pro ayaa leh 460 PPI iyo iPhone 13 Pro Max wuxuu leeyahay 458 PPI. Waqtigeedii, hogaamiyuhu wuxuu ahaa iPhone 4, kaas oo ahaa kii ugu horreeyay ee iPhones ee keenay calaamadaynta Retina. Marka la eego talefannada casriga ah ee maanta, waxa ay bixisay 330 PPI oo keliya, taas oo xitaa markaa Steve Jobs ku andacootay in isha bini'aadamku aanay aqoonsan karin.

Vratislav Holub Si kastaba ha ahaatee, sheegashadan dabcan waa su'aal aad u weyn. Waxay kuxirantahay fogaanta aad ka eegtay aaladda, ama muuqaalkeeda. Dabcan, mar kasta oo aad tan sameyso, si cad ayaad u arki kartaa pixels-ka gaarka ah. Guud ahaan waxaa la sheegaa in isha caafimaadka qabta ay ogaan karto 2 PPI marka la eego "sawir" fogaan ah 190 cm. Laakiin hubaal taas uma samayn doontid si caadi ah. Si kastaba ha noqotee, haddii aad u dheereyso masaafadan tan la isticmaali karo oo hadda ka badan 10 cm, waxaad u baahan tahay oo kaliya inaad haysato cufnaanta pixel ee 30 PPI si aadan mar dambe u kala soocin midba midka kale.
Sawir qaade
Markaa xalin fiican miyaan loo baahnayn? Xitaa taas ma dhihi kartid. pixels badan oo dusha ka yar ayaa si fiican u ciyaari kara midabada, hooskooda iyo iftiinka laftiisa. Indhaha bini'aadamku hadda ma kala saari karaan kala duwanaanshaha, laakiin waxaa loo malayn karaa in haddii bandhiggu uu fiicnaado, ay awood u yeelan doonto inay si fiican u muujiso isbeddellada midabka yar ee aad hore u aragtay. Natiijo ahaan, isticmaalka qalabkan ayaa si fudud u noqon doona mid aad u faraxsan.
Waa kuma hogaamiyaha marka la eego PPI
Sidoo kale halkan jawaab cad lagama heli karo. Waxaa jira farqi u dhexeeya xajmiga yar iyo kan ganaaxa, oo ka soo horjeeda mid weyn oo yar oo adag. Laakiin haddii aad waydiiso su'aasha: "Taleefankee ayaa leh PPI ugu sarreeya", jawaabtu waxay noqon doontaa Sony Xperia XZ Premium. Telefoonkan, oo la soo bandhigay 2017, waxa uu leeyahay muuqaal yar oo 5,46" ah marka loo eego heerarka maanta, laakiin PPI-giisa waa 806,93 naxdin leh.
Samsung Galaxy S21
Taleefannada casriga ah ee cusub, OnePlus 9 Pro waa in si gaar ah loo xusaa, kaas oo leh 526 PPI, halka, tusaale ahaan, Realme GT2 Pro ee dhowaan la soo bandhigay uu leeyahay hal pixel ka yar, i.e. 525 PPI. Vivo X70 Pro Plus, oo leh 518 PPI, ama Samsung Galaxy S21 Ultra oo leh 516 PPI sidoo kale wax weyn ayay qabanayaan. Laakiin markaa waxaa sidoo kale jira taleefanno sida Yu Yutopia, oo bixiya 565 PPI, laakiin wax badan kama naqaanno soo saaraha halkan.
Si kastaba ha ahaatee, waxaa habboon in la sheego xaqiiqda ah in lambarka PPI uu yahay hal calaamad oo kaliya oo muujinaya tayada bandhigga. Dabcan, tani waxay sidoo kale khuseysaa tignoolajiyadeeda, heerka cusbooneysiinta, saamiga isbarbardhigga, dhalaalka ugu sarreeya iyo qiyamka kale. Shuruudaha batteriga ayaa sidoo kale mudan in la tixgeliyo.
