Nrog kev nce qib ntawm kev siv thev naus laus zis, cov khoom siv ua kua siv lead ua kua (LCDs) tau dhau los ua ib feem tseem ceeb ntawm peb lub neej niaj hnub. Los ntawm cov xov tooj ntawm tes, TVs mus rau ntau yam khoom siv hauv tsev, LCD cov ntxaij vab tshaus tau yeej ntau daim ntawv thov nrog lawv cov txiaj ntsig zoo thiab cov yam ntxwv txuag hluav taws xob. Kab lus no yuav tshawb txog lub hauv paus ntsiab lus ntawm kev ua haujlwm, qhov zoo thiab qhov chaw siv ntawm cov ntxaij vab tshaus LCD. Digital LCD zaub cov ntxaij vab tshaus ua rau cov khoom siv cov ntaub ntawv nkag siab ntau dua thiab tuaj yeem nyeem ncaj qha los ntawm cov lej, yog li nws txoj hauv kev ua haujlwm yog dab tsi?
Cov ntxaij vab tshaus LCD siv cov khoom siv hluav taws xob ntawm cov khoom siv ua kua siv lead ua kom pom cov duab. Lub hauv paus ntsiab lus ntawm kev ua haujlwm yog tswj hwm kev npaj ntawm cov kua siv lead ua kua molecules thiab hloov lawv cov kev xa mus rau lub teeb los ua cov duab. Cov txheej txheem tshwj xeeb yog raws li hauv qab no:
Backlight: LCD cov ntxaij vab tshaus feem ntau yog nruab nrog LED backlights los muab lub teeb uas xav tau los ntawm cov ntaub ntawv siv lead ua kua.
Cov kua siv lead ua kua: Cov kua siv lead ua kua molecules yuav hloov lawv txoj kev npaj raws li qhov kev txiav txim ntawm hluav taws xob, yog li cuam tshuam rau kev xa tawm ntawm lub teeb. Los ntawm kev siv cov hluav taws xob sib txawv, cov txheej txheem ntawm cov kua siv lead ua kua molecules tuaj yeem tswj tau kom ua tiav qhov sib txawv grey thiab xim.
Xim lim: Yuav kom tso saib cov duab xim, LCD feem ntau them nrog cov ntxaij lim dej ntawm peb xim: liab, ntsuab, thiab xiav. Los ntawm kev kho qhov sib xyaw ntawm peb cov xim, cov xim nplua nuj raug tsim.
2. Qhov zoo
Cov ntxaij vab tshaus LCD tau dhau los ua qhov kev xaiv tseem ceeb ntawm cov khoom siv hluav taws xob niaj hnub nrog lawv cov txiaj ntsig tshwj xeeb:
Kev daws teeb meem siab: LCD thev naus laus zis tuaj yeem ua tiav cov duab daws teeb meem siab, ua rau cov ntawv nyeem thiab cov duab pom meej dua thiab muag heev.
Kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig: Piv nrog cov tshuaj CRT tsoos, cov ntxaij vab tshaus LCD muaj kev siv hluav taws xob qis dua thiab tsis muaj hluav taws xob muaj kuab paug, uas yog ib puag ncig zoo.
Lub teeb thiab txav tau yooj yim: LCD cov ntxaij vab tshaus feem ntau yog tsim los ua lub teeb thiab nyias, thiab yooj yim rau kev koom ua ke rau hauv ntau yam khoom siv portable.
Kev pom dav dav: Tom qab ntau qhov kev txhim kho, niaj hnub LCD thev naus laus zis tau ua tiav lub kaum sab xis pom dav dua. Txawm hais tias pom los ntawm ntau lub ces kaum, daim duab tseem khaws cov xim zoo thiab ci ntsa iab.
3. Daim ntawv thov teb
Digital LCD modules tau siv dav hauv ntau qhov chaw, feem ntau suav nrog:
Cov khoom siv hluav taws xob: LCD tau dhau los ua cov thev naus laus zis tseem ceeb rau cov xov tooj ntse, ntsiav tshuaj, TVs thiab laptops.
Cov khoom siv muaj: Nws daim ntawv thov nyob rau hauv industrial tswj vaj huam sib luag thiab cov cuab yeej ua rau kev nthuav qhia cov ntaub ntawv ntau intuitive.
Kev tshaj tawm xov xwm: Cov ntawv xov xwm hluav taws xob hauv cov chaw pej xeem xws li cov khw muag khoom thiab chaw nres tsheb siv cov ntxaij vab tshaus LCD kom nyiam cov neeg siv khoom.
Cov cuab yeej kho mob: Hauv cov cuab yeej kho mob, LCD npo npo tuaj yeem tso saib cov neeg mob cov ntaub ntawv kev noj qab haus huv hauv lub sijhawm los pab kev kho mob.
