7 ntu LCD cov ntxaij vab tshaus tsis muaj ib qho "inventor." Hloov chaw, lawv yog raws li kev txhim kho ntawm cov kua siv lead ua kua siv thev naus laus zis. Kev tshawb fawb ntawm RCA tau tsim lub hauv paus, ua raws li kev tsim khoom ntawm TN-LCD los ntawm Swiss cov kws tshawb fawb. Cov tuam txhab Japanese yog thawj zaug ua lag luam thiab siv rau cov khoom siv hluav taws xob, ua lub luag haujlwm tseem ceeb hauv kev pom cov ntaub ntawv hauv cov khoom siv hauv tsev me.
Cov thawj coj ntawm cov ntxaij vab tshaus LCD ntu yog Nyiv Seiko thiab Sharp, uas tau tsim qhov tseeb 7 ntu lcd zaub rau cov saib thiab lub laij lej hauv xyoo 1970s.
Friedrich Reinitzer (kev tshawb pom cov kua muaju), George H. Heilmeier (tus qauv ntawm LCD), thiab Martin Schadt thiab Wolfgang Helfrich (tsim ntawm TN-}LCD) tau tsim lub hauv paus ruaj khov rau daim ntawv thov ntawm 7 LCD ntu cov ntxaij vab tshaus.
Nws ua ntej -tsim cov ntu ntu (xws li xya ntu ntawm tus lej 0-9, lossis cov tsiaj ntawv thiab cov cim) raws li lub tswv yim ntawm ntu ntu code cov ntxaij vab tshaus. Los ntawm kev xaiv energizing tus tsav electrodes, cov cim coj los tso tawm kom pom. Thaum peb sim ua haujlwm kom zoo, peb feem ntau siv lub tshuab kuaj simulate cov teeb liab hluav taws xob nrog AC lub zog los tso saib tag nrho cov ntu LCD.
