1960s
Lub invention ntawm cov kua siv lead ua kua zaub (LCD) tuaj yeem taug qab mus rau xyoo 1960, tshwj xeeb, nws tau pom thawj zaug hauv xyoo 1968 los ntawm American kws tshawb fawb George Heilmeier thiab nws pab neeg.
Heilmeier pib tshawb nrhiav cov kua siv lead ua kua los kawm txog cov txiaj ntsig ntawm cov hluav taws xob sab nraud ntawm cov hluav taws xob hauv cov siv lead ua. Los ntawm sandwiching ib dye-doped kua siv lead ua ntawm ob nplooj ntawv ntawm pob tshab conductive iav thiab siv voltage ntawm ob sab ntawm cov kua siv lead ua txheej, lawv pom tias cov kua siv lead ua kua txheej hloov los ntawm liab mus rau pob tshab. Qhov kev tshawb pom no ua rau Heilmeier thiab nws pab neeg pib kawm seb qhov tshwm sim no puas tuaj yeem siv los tsim cov khoom siv. Tom qab unremitting kev rau siab, lawv thaum kawg pom tau hais tias thawj cov kua siv lead ua kua screen raws li dynamic scattering hom. 1
Tsis tas li ntawd, xyoo 1962, Richard Williams, tus kws kho mob lub cev ntawm Radio Corporation of America (RCA), kuj tau kawm txog cov khoom ntawm cov kua siv lead ua kua. Nws txoj haujlwm tau tsim lub hauv paus rau kev txhim kho tom qab ntawm cov kua siv lead ua kua. 2
Sij hawm dhau mus, cov kua siv lead ua kua siv thev naus laus zis tau txuas ntxiv txhim kho thiab txhim kho, los ntawm qhov pib dynamic scattering hom mus rau tom qab twisted nematic (TN-LCD), super twisted nematic (STN-LCD) thiab nyias zaj duab xis transistor (TFT-LCD) technologies, daim ntawv thov Scope ntawm cov kua siv lead ua kua tau maj mam nthuav dav thiab pib siv dav hauv xyoo 1990s.
