Dab tsi yog qhov zoo ntawm cov ntxaij vab tshaus LCD?

Nrog kev txhim kho txuas ntxiv ntawm cov thev naus laus zis thev naus laus zis, LCD zaub screen tau dhau los ua lub vijtsam tseem ceeb nrog nws cov txiaj ntsig ntau yam. Hnub no kuv yuav qhia rau koj paub txog tsib yam tseem ceeb.

1. Tsis muaj hluav taws xob, kev siv hluav taws xob tsawg, me me cua sov dissipation

Lub hauv paus ntsiab lus ntawm lub vijtsam LCD yog los kho cov duab los ntawm kev sib tw lub kaum sab xis ntawm cov kua siv lead ua kua molecules hauv cov kua siv lead ua kua pixels siv lub teeb tom qab. Nws tsis muaj ultra-high-voltage Cheebtsam sab hauv zoo li CRT, thiab yuav tsis ua rau x-rays ntau dhau vim muaj hluav taws xob siab. Ntxiv mus, lub tshuab qauv thiab Circuit Court yog yooj yim, lub modularity thiab siab kev koom ua ke ntawm lub nti yog txaus los txo cov electromagnetic hluav taws xob generated thaum lub Circuit Court ua hauj lwm. Qhov kev tsim no ncaj qha txo qhov kev siv hluav taws xob ntawm lub voj voog thiab ua kom muaj cua sov tsawg heev. Txawm hais tias lub LCD saib yuav tsim hluav taws xob me me thaum lub sijhawm ua haujlwm, qhov no tuaj yeem daws tau yooj yim los ntawm kev thaiv lub voj voog. Vim yog kev xav txog kev tso cua sov, CRT cov saib xyuas tsis raug tso cai rau qhov tho qhov hauv qhov thaiv npog kom ua rau tawg tawg.

2. Slim thiab hnav

Nws yog qhov tshwm sim ntawm LCD zaub uas ua rau lub tswv yim ntawm lub laptop ua tau. Ib yam li ntawd, txawm hais tias lub desktop LCD saib loj dua qhov loj thiab qhov hnyav dua li lub laptop, nws daj ntseg piv rau qhov loj thiab hnyav CRT saib. Piv nrog rau 15-inch saib, qhov tob ntawm CRT saib feem ntau yog ze li 50 centimeters, thaum qhov tob ntawm lub puab tsaig 'qhov tseeb LCD saib NF-1500MA yog tsawg dua 5 centimeters! Nrog rau kev hloov pauv ntawm cov neeg siv khoom xav thiab ib puag ncig nyob, tib neeg muaj kev xav tau siab dua thiab siab dua rau qhov loj thiab qhov hnyav ntawm cov khoom siv hluav taws xob hauv tsev. Nrog nws cov txiaj ntsig zoo ntawm qhov nyias nyias thiab lub teeb yuag, LCD saib tau dhau los ua cov cuab yeej tso saib feem ntau yuav ua txhaum txoj cai ntawm CRT saib.

3. Kho cov duab kom raug

Lub LCD zaub siv cov kev qhia ncaj qha rau qhov chaw nyob. Nws tuaj yeem hloov cov teeb liab video tso tawm los ntawm daim npav duab los ntawm AD hloov dua siab tshiab, thiab tom qab ntawd ncaj qha daim ntawv qhia video teeb liab ib-rau-ib rau ntawm qhov screen raws li "chaw nyob" teeb liab hauv theem teeb liab. tso tawm rau ntawm LCD pixels. Lub CRT saib tso siab rau ntawm qhov chaw electromagnetic generated los ntawm deflection coil los tswj lub sij hawm scanning ntawm lub electron beam ntawm lub vijtsam kom ua tiav lub hom phiaj ntawm kev nthuav tawm cov duab. Txij li thaum lub zog trajectory ntawm electron beam yog yooj yim cuam tshuam los ntawm ib puag ncig magnetic teb los yog geomagnetism, lub meej positioning ntawm lub electron beam ntawm lub vijtsam yuav ua tsis tau. Yog li ntawd, CRT saib yog qhov ua rau geometric distortion thiab linear distortion ntawm daim duab, uas tsis tuaj yeem raug tshem tawm hauv paus. Qhov no yuav tsis muaj nyob nrog LCD saib. Lub LCD saib tuaj yeem nthuav tawm cov duab zoo ntawm lub vijtsam yam tsis muaj geometric distortion lossis linear distortion.
