1. Tsis muaj hluav taws xob, kev siv hluav taws xob tsawg, tsis muaj cua sov dissipation
Lub hauv paus ntsiab lus ntawm LCD zaub yog thim rov qab lub deflection lub kaum sab xis ntawm cov kua siv lead ua kua molecule hauv cov kua siv lead ua pixel kom ua tiav lub teeb tom qab thiab kho cov duab. Nws tsis muaj nyob rau hauv cov khoom siv nrog ultra-siab voltage zoo li CRT, yog li cov X-ray tshwm sim los ntawm high voltage tsis tshaj tus qauv.Ntxiv mus, lub tshuab qauv thiab Circuit Court yog yooj yim, modular thiab heev integrated txaus kom txo cov electromagnetic. hluav taws xob tsim los ntawm Circuit Court thaum nws ua haujlwm. Xws li tus qauv tsim ncaj qha txo cov hluav taws xob siv hluav taws xob hauv Circuit Court thiab cov nqi calorific tsawg heev.Txawm tias LCD yuav tsim hluav taws xob me me ntawm kev ua haujlwm, nws tuaj yeem daws tau yooj yim los ntawm kev tiv thaiv Circuit Court. Vim tias qhov kev xav ntawm cov cua kub dissipation, CRT zaub yuav tsum tsis txhob tho qhov hauv cov ntaub thaiv npog kom ua rau tawg tawg.
2. Slim thiab lub teeb
Nws yog cov tsos ntawm LCD uas ua rau lub invention ntawm lub laptop ua tau. Ib yam li ntawd, cov duab LCDs loj dua qhov loj thiab qhov hnyav dua li cov laptops, tab sis lawv yog wilder dua li cov duab CRT loj.Piv nrog 15-nti zaub, CRT cov lus qhia feem ntau muaj qhov tob ntawm ze li 50 centimeters, thaum cov kua siv lead ua kua tshiab kawg NF-1500MA. los ntawm Great White Shark yog tsawg dua 5 centimeters tob. Nrog rau kev hloov pauv ntawm kev noj haus thiab kev nyob ib puag ncig, tib neeg xav tau ntau thiab ntau dua ntawm qhov ntim thiab qhov hnyav ntawm cov khoom siv hauv tsev.LCD tau dhau los ua cov khoom siv zoo tshaj plaws los rhuav tshem cov monopoly ntawm CRT zaub vim nws qhov txiaj ntsig zoo ntawm nyias thiab hnav.
3. Kho kom raug cov duab
LCD yog ib qho kev qhia ncaj qha digital chaw nyob hom. Nws tuaj yeem hloov cov teeb liab video tawm ntawm daim npav los ntawm AD, thiab tso saib cov teeb liab video ib los ntawm ib qho ntawm LCD pixels ntawm qhov screen raws li" chaw nyob" teeb liab hauv theem teeb liab. CRT qhia siv lub deflection kauj los tsim electromagnetic teb los tswj lub sij hawm scanning ntawm electron beams ntawm lub vijtsam kom ua tiav lub hom phiaj ntawm kev nthuav tawm cov duab. Vim hais tias lub trajectory ntawm lub electron beam raug cuam tshuam los ntawm ib puag ncig magnetic teb los yog geomagnetic teb, lub meej positioning ntawm lub electron beam ntawm lub screen yuav ua tsis tau. Yog li ntawd, CRT qhia yog prone rau geometric distortion thiab linear distortion, uas muaj peev xwm. tsis raug tshem tawm hauv paus. Qhov no tsis ua tau rau cov kua siv lead ua kua. LCD tuaj yeem tso saib daim duab zoo kawg nkaus ntawm lub vijtsam yam tsis muaj geometric distortion lossis linear distortion.
