Tom qab G.Freidel, kev tshawb fawb ua kua siv lead ua tau nkag mus rau ib ntus qis. Nws kuj tau hais tias lub sijhawm txij li xyoo 1930 txog 1960 yog lub sijhawm dawb huv rau kev tshawb nrhiav kua siv lead ua kua. Yog vim li cas tej zaum tsis muaj kev siv cov kua siv lead ua kua pom nyob rau lub sijhawm ntawd. Txawm li cas los xij, nyob rau lub sijhawm no, kev lag luam semiconductor electronics tau ua tiav kev loj hlob. Txhawm rau kom muaj kev siv cov kua siv lead ua kua hauv cov lus qhia, cov qauv ntawm cov pob tshab electrodes thiab kev koom ua ke ntawm cov kua siv lead ua kua thiab semiconductor circuits-microfabrication technology yog qhov tseem ceeb. Nrog rau kev nce qib ntawm kev lag luam semiconductor, cov thev naus laus zis tau loj hlob.
Nyob rau xyoo 1940, silicon semiconductors tau tsim, siv n-hom semiconductors uas coj electrons thiab p-type semiconductors uas ua qhov los tsim pn interface, thiab diodes thiab transistors tau tsim. Ua ntej qhov no, txhawm rau kom paub txog kev kho kom raug ntawm AC rau DC hauv Circuit Court, lub diode tau siv, thiab lub transistor tau siv los ua kom paub txog kev ua haujlwm amplification. Cov khoom loj thiab hnyav no tuaj yeem hloov tau los ntawm semiconductor diodes thiab transistors. Tsis tas yuav emit electrons rau hauv lub tshuab nqus tsev. Tsuas yog nyob rau hauv cov khoom, tshwj xeeb tshaj yog cov nyias nyias, lub rectification thiab amplification zog yuav tsum tau paub, thiaj li hais tias cov hluav taws xob Circuit Court yuav miniaturized. hloov.
Tom ntej no, siv cov cuab yeej siv kho qhov muag kom ua tiav thinning thiab ultra-miniaturization ntawm cov qauv hluav taws xob hauv hluav taws xob suav nrog diodes thiab transistors. Cov txheej txheem no hu ua lithography luv luv. Nyob rau xyoo 1960, nrog rau kev txhim kho ntawm semiconductor integrated circuit technology, cov khoom siv hluav taws xob tau ua tiav ntxiv me me.
Kev nce qib ntawm cov thev naus laus zis tau hais los saum toj no yog qhov tseem ceeb rau kev siv hauv cov khoom siv ua kua siv lead ua kua. Nrog rau kev txhim kho ntxiv ntawm cov ntaub ntawv tshawb fawb thiab cov khoom siv thev naus laus zis, nrog rau kev tsim cov qauv tshiab thiab kev tsav tsheb thev naus laus zis, kua siv lead ua kua siv thev naus laus zis tau ua tiav sai.
Xyoo 1968, GH Heilmeier, uas ua haujlwm rau RCA hauv Tebchaws Meskas, tau luam tawm DS hom LCD ntaus ntawv. Tom qab ntawd, cov tuam txhab Asmeskas tau ua lawv thawj qhov kev sim siab ntawm digital LCD saib.
LCD saib hloov ntawm DS MODE rau TN MODE
Nyob rau lub Tsib Hlis 1971, Optel Corporation ntawm Tebchaws Meskas, thiab Microma Corporation tau ua tiav cov khoom siv hluav taws xob digital watches nrog DS-mode kua siv lead ua zaub rau kev ua lag luam hauv xyoo 1972. Txawm li cas los xij, cov khoom tsim tawm los ntawm ob lub tuam txhab muaj teeb meem hauv kev ua haujlwm zoo thiab lub neej ntawm cov khoom siv. kua siv lead ua kua, uas tsis tuaj yeem siv tau ntev, thiab tseem muaj teeb meem xws li kev tsav tsheb siab thiab qeeb teb ceev. Hauv qhov sib piv, txhawm rau daws cov teeb meem uas tau hais los saum toj no, Seiko Group hauv Nyij Pooj tsis tau txais DS hom tab sis hom TN zaub, uas ua tiav qhov kev siv tau zoo. TN zaub hom yog hom zaub uas tsis muaj tam sim no overcurrent, yog li cov kav ntev tau txhim kho zoo, lub zog poob kuj tseem me me, thiab nws tuaj yeem siv tsis tu ncua rau 1.5-2 xyoos txawm tias tsis hloov lub roj teeb.
Txij thaum ntawd los, cov kua siv lead ua kua siv thev naus laus zis tau tsim kho sai, thiab TFT-LCD tam sim no tau coj cov xim zoo nkauj thiab muaj yeeb yuj rau peb lub neej.
