Mitundu Yowonetsera Mafoni: Kodi OLED, AMOLED, Retina ndi Zambiri Zikutanthauza Chiyani?

U mafoni am'manja nthawi zambiri timakumana ndi zilembo zosiyanasiyana pazowonetsa zawo. Komabe, ukadaulo wa LCD womwe unkagwiritsidwa ntchito kale udasinthidwa ndi OLED, pomwe, mwachitsanzo, Samsung imawonjezera zolemba zosiyanasiyana. Kuti mukhale ndi chidziwitso pang'ono, pansipa mutha kuwona mwachidule matekinoloje omwe angagwiritsidwe ntchito pazowonetsera zosiyanasiyana. Pa nthawi yomweyo, Retina ndi chizindikiro chabe malonda.

LCD

Chiwonetsero cha crystal yamadzimadzi ndi chipangizo choonda komanso chosalala chokhala ndi chiwerengero chochepa chamitundu kapena mapikseli a monochrome olumikizidwa kutsogolo kwa chowunikira kapena chowunikira. Pixel iliyonse imakhala ndi mamolekyu amadzimadzi amadzimadzi omwe amaikidwa pakati pa maelekitirodi awiri owonekera komanso pakati pa zosefera ziwiri zokhala ndi polarization axs perpendicular kwa mnzake. Popanda makhiristo pakati pa zosefera, kuwala komwe kumadutsa mu fyuluta imodzi kukhoza kutsekedwa ndi fyuluta inayo.

OLED

Organic Light-Emitting Diode ndi mawu achingerezi otanthauza mtundu wa LED (ndiko kuti, ma electroluminescent diode), pomwe zida za organic zimagwiritsidwa ntchito ngati chinthu cha electroluminescent. Ukadaulowu umagwiritsidwa ntchito mobwerezabwereza m'mafoni am'manja, popeza Apple adagwiritsa ntchito komaliza mu iPhone 11, pomwe mbiri yonse yamitundu 12 idasinthiratu ku OLED mpaka 1987.

Monga amanenera mu Czech Wikipedia, kotero mfundo ya teknoloji ndi yakuti pali zigawo zingapo za organic pakati pa anode yowonekera ndi cathode yachitsulo. Panthawi yomwe voteji ikugwiritsidwa ntchito ku imodzi mwa minda, ndalama zabwino ndi zoipa zimapangidwira, zomwe zimaphatikizana muzitsulo zotulutsa mpweya ndipo motero zimatulutsa kuwala.

PMOLED

Izi ndi zowonetsera zokhala ndi matrix okhazikika, omwe ndi osavuta komanso amapeza kugwiritsa ntchito kwawo makamaka kumene, mwachitsanzo, malemba okha ayenera kuwonetsedwa. Monga momwe zilili ndi mawonedwe osavuta a LCD, ma pixel omwewo amawongoleredwa mwachisawawa, ndi grid matrix omwe amawoloka mawaya. Chifukwa chakugwiritsa ntchito kwambiri komanso kusawoneka bwino, ma PMOLED ndi oyenera makamaka mawonedwe okhala ndi ma diagonal ang'onoang'ono.

AMOLED

Zowonetsera zowoneka bwino za matrix ndizoyenera kugwiritsa ntchito zithunzi zokhala ndi mawonekedwe apamwamba, mwachitsanzo, kuwonetsa makanema ndi zithunzi, ndipo amagwiritsidwa ntchito kwambiri pama foni am'manja. Kusintha kwa pixel iliyonse kumachitika ndi transistor yake, yomwe imalepheretsa, mwachitsanzo, kuthwanima kwa mfundo zomwe zimayenera kuwunikira nthawi zingapo zotsatizana. Ubwino wodziwikiratu ndi mawonekedwe apamwamba kwambiri, kuwongolera kwazithunzi komanso, pomaliza, kugwiritsa ntchito mochepera. Mosiyana ndi zimenezi, zovutazo zimaphatikizapo mawonekedwe ovuta kwambiri a chiwonetserochi ndipo motero mtengo wake wapamwamba.

PHINDANI

Apa, mawonekedwe a OLED amayikidwa pazinthu zosinthika m'malo mwa galasi. Izi zimathandiza kuti chiwonetserochi chizigwirizana bwino ndi malo, monga dashboard kapena visor ya chisoti kapena magalasi. Zomwe zimagwiritsidwa ntchito zimatsimikiziranso kukana kwamakina, monga kugwedezeka ndi kugwa.

APO

Ukadaulo uwu umapangitsa kuti zitheke kupanga chiwonetsero chofikira mpaka 80%. Izi zimatheka ndi cathode yowonekera, anode ndi gawo lapansi, zomwe zingakhale galasi kapena pulasitiki. Izi zimalola kuti chidziwitso chiwonetsedwe m'mawonekedwe a wogwiritsa ntchito pamalo owoneka bwino, ndikupangitsa kukhala pafupi kwambiri ndi FOLED.

Chizindikiro cha retina

Ili ndi dzina chabe lamalonda la zowonetsera zochokera pa IPS panel kapena ukadaulo wa OLED wokhala ndi kachulukidwe ka pixel kwambiri. Imathandizidwa ndi Apple, yomwe idalembetsedwa ngati chizindikiro ndipo sichingagwiritsidwe ntchito ndi wopanga wina aliyense pokhudzana ndi zowonetsera.

Izi ndizofanana ndi zilembo za Super AMOLED zomwe Samsung imagwiritsidwa ntchito pazida zake. Imayesa kuwonjezera ma subpixels ambiri pomwe ili ndi mawonekedwe ocheperako, chithunzi chomveka bwino komanso kugwiritsa ntchito mphamvu zochepa.
