Cov kev zoo ntawm cov muaj kua ua kua dej muaj tshwm sim:
1. Nrog rau kev txhim kho ntawm cov ntxaij lim dej LCD tau ntau xyoo, lub tshuab tau dhau los lawm, thiab cov ntawv siv tau ua dhau los thiab paub tab, txuag chaw.
2, qhov sib txawv ntawm cov kev lag luam hauv LCD thiab cov tshuaj CRT yog lub hwj huam noj thiab ntim, cov 17-nti CRT, lub hwj huam ntawm 80W, thiab lub hwj huam tau siv ntawm 17-nti LCD feem ntau yog hais txog 40W, ntev lub sij hawm, LCD nyob rau hauv cov nqe lus ntawm lub zog txuag Tau piav raws li pom zoo.
3. Cov khoom siv lead ua kua dej kuj yog cov phooj ywg zoo tib yam nkaus xwb. Qhov no yog vim tsis muaj cov khoom ua hluav taws xob siab xws li CRTs nyob rau hauv cov khoom siv lead ua kua, yog li tsis muaj teeb meem ntawm X-rays ntau tshaj qhov siab qhov hluav taws xob los ntawm kev siab zog. Feem ntau hais lus, cov hluav taws xob qis dua qis dua CRT.
4. Muaj cov duab CRT muaj ib lub teb electromagnetic generated los ntawm ib tug deflection yoke kom tswj tau lub nqaj hlau electron, tab sis lub nqaj hlau electron tsis positioned ntawm qhov screen. Yog li, CRT qhia yuav muaj ntau hom kev sib txawv hauv cov duab geometric thiab kev tawm txawv. Cov kua siv lead ua kua tsis muaj ib qho teebmeem txawv txav los yog teeb meem distortion vim nws qhov teeb meem, uas yog ib qho tseem ceeb heev.
Muaj cov lus qhia feem ntau ploj, nrog me ntsis kev txawj ntse, uas yog yooj yim kho.
1, cov duab ntawm tag nrho cov tshuab tsis muaj hluav taws xob yuav tsum tau hais tias yuav yog ib qho yooj yim yuam kev, lub dav LCD saib extension fais fab mov thiab lwm fais fab mov ob, qhov ntau yog off-board, tab sis tsis muaj teeb meem dab tsi ntawm lub hwj chim, nws cov qauv zoo dua li lub hwj huam ntawm CRT saib Muaj ntau yam yooj yim, cov Cheebtsam me yog feem ntau raug rau kev puas tsuaj, xws li fuses, cov tswv yim inductors, hloov hlab, Zener diodes, etc. Qhov tsawg dua kev txhaum yog tias lub hwj huam los ntawm CPU ntawm qhov motherboard tsis tuaj yeem pib. Qhov no yog qhov yooj yim heev. Nws yog los ntawm qhov tseem ceeb tswj lub rooj tsav tsheb mus rau CPU, thiab tom qab ntawd ces tus CPU tawm kev teeb tsa kev tswj fais fab kev hloov hluav taws xob ua ke.
2. Cov duab yog dub, tab sis lub hwj huam qhia yeej ib txwm nyob. Qhov teeb meem no feem ntau yog tshwm sim los ntawm kev kub ntxhov siab. Feem ntau, tus npo LCD yog tso tawm rau hauv qhov no, uas yog "strabismus". Lub hom phiaj ntawm kev soj ntsuam yog nyob rau ntawm kev sib piv ntawm txoj kev kho. Lub plhaub loj-siab ntawm cov kua siv ua kua dej tam sim no feem ntau yog tsim los siv, thiab ob qho tib si tau ua phem rau tib lub sijhawm tsis yooj yim sua. Feem ntau, lub tshuab qub yog ib qho teeb meem nrog lub tshuab hluav taws xob tawm qauv thiab lub teeb lub raj, thiab qhov kev tiv thaiv kev tiv thaiv thiab qhov teeb meem ntawm lub tshuab tshiab kuj muaj ntau.
3, qhov screen ci ci lossis kab tsaus nti xws li ib qho teeb meem, feem ntau ntawm qhov LCD tsis ua hauj lwm. Lub kab teeb meem yog qhov teeb meem nrog cov hlua txuas rau lub npo LCD. Cov kab tsaus yog feem ntau ntawm lub cev ntawm qhov screen. Qhov saum toj no ob qhov teeb meem yog qhov raug nplua rau lub tshuab. Yog tsis muaj tus nqi txij nkawm, vim hais tias tus nqi ntawm qhov screen yog dhau Taller.
4, Huaping lossis white screen Qhov teeb meem no feem ntau yog qhov teeb meem ntawm qhov ntsuas qhov teeb meem, yog hais tias lub vijtsam cov voj voos nyob rau ntawm daim npav, ces nws yuav tsum yog lub niam txiv tsis ua haujlwm, yog tias lub vijtsam cov vijtsam muaj nyob rau ntawm LCD, Nws yuav tsum tau hloov, thiab txoj kev pheej hmoo ntawm kev txij nkawm kuj zoo heev.
5, xim tsis ua hauj lwm tsis tuaj yeem feem ntau nkag mus rau cov kev hloov kho tu kom haum.
6. Lwm yam kev cuam tshuam tsis tshua muaj tshwm sim: Nyob hauv ntau hom kev ua haujlwm, tej zaum yuav muaj kev cuam tshuam hauv cov kua siv lead ua kua, feem ntau yog qhov qub, thiab qee qhov yog coj tuaj rau hauv Circuit Court, vim hais tias qhov tshwj xeeb cov txheej txheem ntawm cov kua siv lead ua kua Tsuas yog cov teeb meem pom hauv cov qauv kev khiav hauj lwm muaj peev xwm pom tias yog cov kev ua yuam kev.
