Futhi uma ucabanga ukuthi ama-smartphones akamuva akhula njalo le nombolo, akulona iqiniso ngokuphelele. Umholi uyidivayisi kusukela ngo-2017.

Kunjalo, lapho wenza lokhu ngokuseduze, yilapho ungabona ngokucace kakhudlwana amaphikseli ngamanye. Ngokuvamile kushiwo ukuthi iso lomuntu elinempilo likwazi ukubona i-2 PPI lapho libheka "isithombe" esikude ne-190 cm. Kodwa ngokuqinisekile ngeke ukwenze lokho ngokujwayelekile. Kodwa-ke, uma unweba leli banga kokusebenzisekayo futhi manje okuvame kakhulu okungu-10 cm, udinga kuphela ukuba ne-pixel density engu-30 PPI ukuze ungabe usakwazi ukuhlukanisa komunye nomunye.

Ngakho-ke ingabe ukulungiswa okungcono kakhulu akudingekile? Awukwazi ngisho ukusho lokho. Amaphikseli engeziwe endaweni encane angadlala kangcono ngemibala, imithunzi yawo kanye nokukhanya ngokwako. Iso lomuntu ngeke lisakwazi ukuhlukanisa umehluko, kodwa kungacatshangwa ukuthi uma isibonisi sicolekile, sizokwazi ukuveza kangcono ukushintshwa kombala okuncane osuvele ukubonile.

Kuma-smartphones amasha, i-OnePlus 9 Pro kufanele iqokwe, ene-526 PPI, kuyilapho, ngokwesibonelo, i-Realme GT2 Pro esanda kwethulwa ine-pixel eyodwa kuphela ngaphansi, okungukuthi i-525 PPI. I-Vivo X70 Pro Plus, ene-518 PPI, noma i-Samsung Galaxy S21 Ultra ene-516 PPI nayo yenza kahle. Kodwa-ke kukhona amafoni afana ne-Yu Yutopia, enikeza i-565 PPI, kodwa asazi okuningi ngalo mkhiqizi lapha.
