Hom Zaub Txawb: Dab tsi yog OLED, AMOLED, Retina thiab ntau dua?

U xov tooj ntawm tes peb feem ntau tuaj hla cov ntawv sib txawv rau lawv cov lus qhia. Txawm li cas los xij, yav dhau los siv LCD thev naus laus zis tau hloov los ntawm OLED, thaum, piv txwv li, Samsung ntxiv ntau cov ntawv rau nws. Txhawm rau kom muaj qhov pom tseeb me ntsis, hauv qab no koj tuaj yeem pom cov ntsiab lus ntawm cov thev naus laus zis uas tuaj yeem siv rau hauv cov duab sib txawv. Nyob rau tib lub sijhawm, Retina tsuas yog daim ntawv lo lag luam xwb.

LCD

Cov kua siv lead ua kua yog ib qho khoom siv nyias thiab tiaj tiaj uas muaj cov xim tsis muaj xim lossis monochrome pixels nyob rau pem hauv ntej ntawm lub teeb los yog lub teeb pom kev. Txhua pixel muaj cov kua siv lead ua kua molecules muab tso rau ntawm ob lub pob tshab electrodes thiab ntawm ob lub polarizing lim, nrog cov polarization axes perpendicular rau ib leeg. Yog tsis muaj cov muaju ntawm cov lim dej, lub teeb dhau los ntawm ib lub lim yuav raug thaiv los ntawm lwm lub lim.

OLED

Organic Light-Emitting Diode yog lo lus Askiv rau hom LED (uas yog, electroluminescent diodes), uas cov khoom siv organic siv los ua cov khoom siv hluav taws xob. Cov thev naus laus zis no tau siv ntau thiab ntau zaus hauv cov xov tooj ntawm tes, txij li thaum Apple siv nws kawg hauv iPhone 11, thaum tag nrho cov ntaub ntawv ntawm 12 tus qauv twb tau hloov mus rau OLED. Tab sis txawm li ntawd los, nws siv sijhawm ntev heev, vim tias cov cuab yeej siv niaj hnub. rov qab mus rau xyoo 1987.

Raws li lawv hais hauv Czech Wikipedia, yog li lub hauv paus ntsiab lus ntawm kev siv tshuab yog tias muaj ob peb txheej ntawm cov organic teeb meem ntawm pob tshab anode thiab cov hlau cathode. Thaum lub sij hawm thaum voltage yog siv rau ib qho ntawm cov teb, qhov zoo thiab tsis zoo nqi yog induced, uas ua ke nyob rau hauv lub emitting txheej thiab yog li tsim lub teeb hluav taws xob.

PMOLED

Cov no yog cov lus qhia nrog passive matrix, uas yooj yim dua thiab pom lawv siv tshwj xeeb tshaj yog qhov twg, piv txwv li, tsuas yog cov ntawv yuav tsum tau tso tawm. Raws li nrog cov duab LCD yooj yim dua, cov pixels ntawm tus kheej raug tswj tsis tu ncua, los ntawm daim phiaj matrix ntawm kev sib txuas ntawm cov xov hlau. Vim muaj kev noj ntau dua thiab cov zaub tsis zoo, PMOLEDs yog qhov tshwj xeeb tshaj yog tsim rau cov zaub nrog cov kab pheeb ces kaum me.

AMOLED

Active matrix displays yog haum rau cov duab-intensive daim ntaub ntawv nrog siab daws teeb meem, piv txwv li, tso saib video thiab graphics, thiab yog dav siv nyob rau hauv lub xov tooj ntawm tes. Kev hloov ntawm txhua pixel yog ua los ntawm nws tus kheej transistor, uas tiv thaiv, piv txwv li, blinking ntawm cov ntsiab lus uas yuav tsum tau teeb pom kev thaum ob peb lub voj voog sib law liag. Qhov zoo meej yog cov zaub ntau dua, cov duab ua kom pom tseeb dua thiab, thaum kawg, qis dua. Conversely, qhov tsis zoo muaj xws li ib tug complex qauv ntawm cov zaub thiab yog li nws tus nqi siab dua.

FOLD

Ntawm no, cov qauv OLED tau muab tso rau ntawm cov khoom siv hloov pauv hloov ntawm iav. Qhov no tso cai rau cov zaub kom zoo dua rau qhov chaw, xws li dashboard lossis txawm tias lub visor ntawm lub kaus mom hlau lossis iav. Cov khoom siv kuj tau lees tias muaj kev tiv thaiv ntau dua, xws li kev poob siab thiab poob.

TAM SIM NO

Cov thev naus laus zis no ua rau nws muaj peev xwm tsim cov duab nrog txog li 80% lub teeb xa mus. Qhov no yog ua tiav los ntawm pob tshab cathode, anode thiab substrate, uas tuaj yeem yog iav lossis yas. Qhov tshwj xeeb no tso cai rau cov ntaub ntawv tuaj yeem tso tawm hauv cov neeg siv qhov kev pom ntawm lwm qhov chaw pob tshab, ua rau nws ze heev rau FOLED.

Retina npe

Qhov no tsuas yog lub npe lag luam rau cov lus qhia raws li IPS vaj huam sib luag lossis OLED thev naus laus zis nrog lub pixel ceev dua. Nws yog qhov tseeb txhawb nqa los ntawm Apple, uas tau sau npe ua lag luam thiab tsis tuaj yeem siv los ntawm lwm cov chaw tsim khoom hauv kev sib txuas nrog cov khoom siv.

Qhov no zoo ib yam li Super AMOLED daim ntawv lo siv los ntawm Samsung ntawm nws cov khoom siv. Nws sim ntxiv cov subpixels ntxiv thaum muaj ib daim ntawv zoo dua qub, cov duab pom tseeb dua thiab siv zog qis dua.
