Cov keeb kwm kev loj hlob ntawm cov zaub screen
Cov keeb kwm ntawm cov ntxaij vab tshaus hnub rov qab mus rau lub xyoo pua 20th thaum ntxov thaum cathode ray hlab (CRTs) tau tsim thawj zaug. CRTs tau siv hauv TV thiab khoos phis tawj saib rau ntau xyoo lawm thiab tseem yog thawj cov khoom siv thev naus laus zis kom txog rau thaum kev nthuav qhia cov vaj huam sib luag tiaj tus hauv xyoo 1990s.
Thawj lub vaj huam sib luag vaj huam sib luag yog cov kua siv lead ua kua (LCD) uas tau tsim nyob rau xyoo 1960. Txawm li cas los xij, nws tsis yog txog thaum xyoo 1990 uas LCD thev naus laus zis tau los ua qhov zoo rau kev siv hauv cov neeg siv khoom siv vim kev nce qib hauv kev tsim khoom thiab kev tsim cov khoom tshiab.
Lwm lub vaj huam sib luag vaj huam sib luag vaj huam sib luag, plasma zaub vaj huam sib luag (PDP), kuj tau tsim nyob rau xyoo 1960. PDPs tau siv hauv TV loj hauv xyoo 2000s thaum ntxov tab sis thaum kawg tau hloov pauv los ntawm LCD thiab tom qab ntawd, cov khoom siv hluav taws xob hluav taws xob (OLED) cov lus qhia.
OLED cov duab tau tsim thawj zaug hauv xyoo 1980s tab sis tsis tau ua lag luam mus txog thaum ntxov 2000s. OLEDs muaj ntau qhov zoo dua li LCDs suav nrog lub sijhawm teb sai dua, qhov sib piv ntau dua, thiab pom dav dua. OLED cov lus tam sim no feem ntau siv hauv smartphones, TVs, thiab lwm yam khoom siv.
Nyob rau hauv xyoo tas los no, ob peb lub tswv yim tshiab tau tshwm sim suav nrog quantum dot zaub thiab microLED cov lus. Cov thev naus laus zis no muab cov kev daws teeb meem siab dua, cov xim ci dua, thiab kev siv zog ntau dua piv rau yav dhau los cov thev naus laus zis.
Zuag qhia tag nrho, keeb kwm ntawm cov ntxaij vab tshaus yog ib zaj dab neeg ntawm kev txhim kho txuas ntxiv thiab kev txhim kho, uas tau tsav los ntawm kev nce qib hauv cov ntaub ntawv tshawb fawb, kev tsim khoom, thiab cov neeg siv khoom xav tau kom zoo dua thiab muaj txiaj ntsig zoo dua.
