Thaum ntxov, lub xov tooj ntawm tes muaj peev xwm khaws cia hauv tsev qiv ntawv thiab tib lub sijhawm uas muaj qhov loj me me tuaj yeem pom hauv qee cov dab neeg zoo heev. Tam sim no, e-phau ntawv nrog e-ink tuaj yeem yooj yim yuav ntawm yuav luag txhua lub khw muag khoom kho vajtse lossis xaj online. Lawv yog dab tsi, qhov zoo thiab qhov tsis zoo lawv muaj, qhov no yuav tau tham hauv peb tsab xov xwm.
Smart Ink
Cov ntawv hluav taws xob siv los ntawm cov ntawv e-ink hnub rov qab mus rau 70s ntawm lub xyoo pua 20th. Thawj cov cuab yeej siv tshuab no hu ua "hericon". Hauv nws, qhov chaw nruab nrab ntawm ob daim ntawv pob tshab tau ntim nrog ib txheej nyias ntawm cov pob polyethylene me me thiab tom qab ntawd ntim cov roj. Txhua lub pob tau pleev xim rau hauv ob xim: thawj ib nrab ntawm qhov chaw yog dawb, thiab lub thib ob yog dub. Nyob ntawm qhov kos npe ntawm tus nqi them, txheej txheej tig mus rau ib txoj kev lossis lwm qhov. ATRaws li qhov tshwm sim, ib qho xim dawb lossis xim dub tshwm rau saum npoo ntawm cov khoom siv no. Nyob rau hauv kev xyaum, xws li ib tug invention tsis tau dav siv, tab sis nyob rau tib lub sij hawm nws txhawb inventors rau kev tshawb fawb tshiab. Niaj hnub nimno cov phau ntawv hluav taws xob nrog hluav taws xob number case ua haujlwm ntawm lub hauv paus ntawm LCD matrix, uas muaj ib txheej ntawm pob tshab microcapsules. Txhua ntawm lawv muaj cov kua nplaum uas muaj cov xim dawb thiab xim dub. Cov qub raug them zoo thiab tom qab raug them tsis zoo. Thaum cov nqi zoo nkag mus rau hauv lub xovtooj ntawm tes, cov khoom dawb yuav thaws tawm hauv qab ntawm "daim ntawv hluav taws xob" thiab ntab mus rau saum npoo. Negatively them dub hais, ntawm qhov tsis tooj, yuav tau attracted downwards. Yog li ntawd, qhov taw tes ntawm daim duab nyob rau hauv qhov chaw no yuav tig dawb. Yog tias koj siv cov nqi tsis zoo rau cov tshuaj ntsiav, cov txheej txheem rov qab yuav tshwm sim, thiab hauv qhov chaw no pixel yuav tig dub.
txiaj ntsig
E-phau ntawv nrog tus cwj mem hluav taws xob tuaj yeem tuav lub tsev qiv ntawv zoo uas koj tuaj yeem nqa nrog koj txhua qhov chaw. Ntau tus "nyeem ntawv" muaj peev xwm nkag mus rau hauv Is Taws Nem, qhov twg koj tuaj yeem ntxiv koj cov khoom sau nrog tus muag khoom tshiab. Tsis tas li ntawd, cov khoom siv zoo li no, raws li txoj cai, muaj lub mloog pob ntseg, yog tias koj ob lub qhov muag nkees, koj tuaj yeem mloog audiobook lossis so nrog suab paj nruag. Qhov txiaj ntsig tseem ceeb tshaj plaws uas e-phau ntawv nrog tus cwj mem muaj dhau lub ntsuas yog tias daim duab tsis flicker rau nws. Qhov no txhais tau hais tias qhov muag yuav tsis nkees. Vim yog siv hluav taws xob tsawg, tus nqi yuav kav ntev li ob peb lub lis piam, thiab txawm tiastua lub zog, cov duab yuav nyob twj ywm ntawm qhov screen rau lub sijhawm ntev, txij li tus tsov ntxhuav feem ntawm lub zog tsuas yog siv rau ntawm qhov pib kos duab. Lub teeb yuag ntawm lub cuab yeej thiab kev ywj pheej ntawm cov duab zoo los ntawm lub kaum sab xis ntawm lub vijtsam yog ib qho ntxiv ntxiv uas tso cai rau cov cuab yeej zoo li no kom ua tiav kev sib tw nrog cov ntawv dawb.
Flaws
E-ink e-phau ntawv muaj peb qhov tsis zoo. Thawj qhov tsis zoo yog qhov tsawg ceev ntawm cov duab tsim. Vim li no, saib cov vis dis aus ntawm "tus cwj mem" screen yuav tsis ua haujlwm. Qhov thib ob drawback yog tias lub teeb pom kev zoo tseem xav tau rau kev nyeem ntawv. Txawm tias niaj hnub "nyeem ntawv" tsis tuaj yeem khav ntawm keeb kwm ntawm nplooj ntawv ntawm kev dawb huv. Ntawm chav kawm, nws yog lub teeb heev, tab sis kom deb li deb nws yog cov xim tsis zoo rau cov ntawv zoo tib yam thiab nyob rau hauv lub teeb qis nws zoo li me ntsis grey. Qhov thib peb thiab zaum kawg drawback yog qhov pos huab zeem muag ntawm cov ntxaij vab tshaus xim. Txog tam sim no, hom nyeem ntawv no kim dhau lawm, nplooj ntawv hloov pauv siv sijhawm ntev (txog 2-3 vib nas this), thiab roj teeb lub zog siv sai heev.
Prospects
Txawm li cas los xij, cia siab rau cov khoom siv pheej yig thiab zoo nrog cov xim "hluav taws xob" number case tseem nyob. Nws tau paub tias PocketBook tab tom ua haujlwm tam sim no, thiab thawj "nyeem ntawv" ntawm hom no yuav tshwm sim hauv CIS thaum kawg ntawm 2013. Yog li, txawm tias muaj kev sib tw los ntawm cov ntsiav tshuaj thiab smartphones, thev naus laus zis tau hloov zuj zus. Thiab hnub tsis nyob deb thaum ib phau ntawv zoo e-phau ntawv nrog cov xim number case rau ntawm lub ntsej muag dawb-dawb zoo meej yuav muaj.
