Muaj ntau ntau low-end LCD ntxaij nyob rau hauv kev ua lag luam rau kev muag khoom, thiab ntau tus neeg tau txais kev pab uas xav tias lawv yuav xav tau cov ntxig zoo LCD nrog tsawg heev. Nyob rau hauv qhov tseeb, cov lus qhia low-end LCD muaj ntau yam ua yuam kev. Peb yuav tsum ua kom zoo dua tom qab ntsuas thiab txiav txim. Dab tsi yog qhov tsis zoo ntawm cov low-end LCD zaub?
Cov low-end LCD zaub tsuas yog cov kev tsis zoo hauv qab no:
Ua ntej, lub sij hawm sib luag
Lub sij hawm teb yog ib qho kev qhia tshwj xeeb ntawm cov kua siv lead ua kua. Lub sij hawm teb ntawm cov kua siv lead ua kua yog hais txog qhov kev sib pixel ntawm txhua qhov pixel ntawm cov khoom xa mus rau lub teeb liab. Thaum lub sijhawm teb luv luv, tsis muaj duab smearing tshwm sim thaum cov duab txav tso tawm. Qhov no tseem ceeb heev thaum ua si thiab saib cov duab ceev ceev. Lub sijhawm txaus los teb kom paub tseeb tias qhov ua tiav ntawm daim duab. Tam sim no, cov kua hluav taws xob hauv cov lag luam hauv lub khw muaj kev txiav txim siab zoo tshaj plaws nyob rau hauv lub sij hawm teb nrog piv ua ntej, feem ntau ntawm 40ms. Tab sis tseem ua tsis tau raws li cov kev cai rau 3D ua si thiab kev ua yeeb yaj kiab DVD zoo.
Thib ob, qhov interface
1. Lub digital interface ntawm kua siv lead ua kua yog yooj yim. Nyob rau hauv kev tshawb xav, cov kua siv lead ua kua yog lub cuab yeej dawb huv, thiab kev txuas mus rau lub tshuab computer tseem yuav tsum yog lub digital interface. Qhov zoo ntawm kev siv lub digital interface yog nws tus kheej. Ua ntej, nws tuaj yeem txo qhov teeb liab thiab cuam tshuam rau hauv txoj kev hloov ntawm analog-rau-digital; txo qhov hloov khoom nruab nrog thiab hloov khoom; secondly, nws tsis tas yuav kho lub suab ntau zaus thiab vector.
2. Txawm li cas los xij, feem ntau ntawm cov kua qis qis qis hauv kev lag luam siv cov analog interfaces, thiab muaj teeb meem xws li cov kev taw qhia kev sib kis yooj yim rau kev cuam tshuam, yuav tsum tau ntxiv cov khoom sib txuas mus rau cov khoom sib piv hauv cov duab, thiab tsis muaj peev xwm hloov mus rau digital interfaces. Tsis tas li ntawd, yuav kom tsis txhob muaj qhov pom ntawm pixel flicker, nws yog ib qho tsim nyog kom muab qhov sib thooj lub suab ntau, vector, thiab cov teeb liab analog. Tsis tas li ntawd, lub digital interface ntawm cov kua siv lead ua kua tseem tsis tau tsim ib qho kev cai sib txuas, thiab tso tawm cov ntawv teev lus nrog cov zis tsis yog hauv cov lag luam. Yog li ntawd, qhov tseem ceeb ntawm LCDs yog qhov nyuaj rau kev paub tag nrho. Rau tam sim no, qhov tshwm sim ntawm kev noj tshuaj ntxov yog los siv tus nqi siab mus yuav khoom.

Qhov peb, qhov ci thiab qhov sib txawv
Koj puas xav mus ua si ib lub teeb tsom? Qhov no chij yog hais txog kev ci ntsa iab thiab qhov sib txawv hauv LCD monitor. Txij li cov kua siv lead ua kua molecules tsis tuaj yeem tawm qhov teeb ci ntawm lawv tus kheej, cov kua siv lead ua kua yuav tsum tau vam khom lwm cov teeb ci sab nraud los pab lub teeb emission. Feem ntau, 140 lumens ib square meter txaus. Qee cov lag luam tseem muaj qhov sib txawv ntawm cov txheej txheem parameter thiab cov qauv tseeb. Qhov no yuav piav qhia, uas yog, qee qhov ntsuas me me hauv LCD tau raug siv hauv cov computers hauv yav dhau los, siv ob lub teeb los kho, kom lawv qhov ci thiab qhov sib txawv tsis zoo heev.
Plaub, qhov pom lub kaum ntse ntse
Thaum ntxov saib cov ces kaum ntawm LCDs tsuas yog 90 degree, thiab lawv tsuas yog saib ntawm lub hauv ntej. Ntau qhov ci ntsa iab thiab xim distortion yuav tshwm sim thaum pom ntawm sab. Nta hnub no, lub qhov muag pom ntawm cov kua siv lead ua kua hauv kev lag luam yog feem ntau nyob ib ncig ntawm 140 degrees, uas txaus rau kev siv tus kheej. Txawm li cas los xij, yog hais tias muaj coob tus neeg saib tib lub sij hawm, qhov teeb meem ntawm distortion yog qhia.
