Thaum hais txog qhov loj me ntawm lub vijtsam TV lossis ntsuas saib, lawv qhia tsis yog qhov dav thiab qhov siab, tab sis kab pheeb ces kaum. Qee zaum qhov pom ntawm daim duab yog me dua CRT npo lossis LCD ntsuas. Txhawm rau kom paub tias lub chaw tsim khoom tau dag koj, koj tuaj yeem ntsuas cov kab pheeb ces kaum koj tus kheej.
Cov Lus Qhia

Cov raj TVs thiab saib tau sib txawv ntawm cov sib txawv hauv pem hauv ntej vaj huam sib luag tsim. Hauv qee qhov ntawm lawv, CRT npo tiv thaiv sab nraud nrog rau ib qho me me ntawm lub sab phab ntsa, thaum nyob hauv lwm tus, ib feem ntawm nws sab pem hauv ntej yog muab zais hauv qab thav duab. Hauv thawj qhov xwm txheej, qhov kev ncua deb ntawm cov fab ntawm qhov ciaj ciam ntawm phosphor (thiab tsis yog lub khob nws tus kheej) yog yuav tsum ntsuas, thiab hauv ob, ntawm qhov fab ntawm cov ces kaum ntawm cov yas thav duab.

Siv tus pas ntsuas tus qauv los ntsuas lub LCD npo lossis flat screen CRT. Yog tias CRT lub vijtsam yog convex, koj yuav tsum tau siv cov ntsuas 's hloov pauv. Lub thawv ntawv yog tseem haum, uas tuaj yeem nqa ntawm qhov muag zaub nrog cov ntawv nthuav qhia hauv qee lub khw muag khoom kho vajtse. Tsis txhob siv xov tooj hlau ntsuas - nws tuaj yeem khuam qhov screen.

Ntawm kev xa xov raj thiab qee cov raj ntsuas loj dua, lub vijtsam yog them nrog hluav taws xob zoo li qub thaum lub sijhawm ua haujlwm. Tom qab kov lub vijtsam, tus nqi hloov mus rau tus neeg. Tom qab ntawd, kov ib qho av lossis tsuas yog cov khoom siv hlau loj (txawm tias lub kav hlau txais xov ntawm tib lub TV), koj tuaj yeem tau txais cov mob hluav taws xob, thiab khaws lub xov tooj ntawm tes lossis lwm yam khoom siv hluav taws xob - ua rau nws xoob. Txhawm rau tiv thaiv qhov no los ntawm tshwm sim, tawm hauv TV lossis saib xyuas ob peb teev ua ntej ntsuas lub kab pheeb ces kaum.

Thawj txoj kev ntsuas ntsuas yog raws li hauv qab no. Siv tus pas ntsuas lossis lub ntsuas hluav taws xob ntsuas kom ntsuas qhov kev sib txawv ntawm qis dua sab laug thiab sab xis saum toj ntawm lub vijtsam. Tsis txhob siv lub zog tseem ceeb rau nws, tshwj xeeb yog tias nws yog cov kua siv lead ua kua. Hloov pauv qhov ntsuas kev ntsuas, tawm hauv centimeters lossis millimeters, mus rau hauv nti: 1 nti sib npaug 2.54 cm.

Txhawm rau siv txoj kev thib ob, ntsuas qhov dav thiab qhov siab ntawm lub vijtsam cais. Tom qab ntawd suav tus nqi ntawm kab pheeb ces kaum siv Pythagorean theorem: d = sqrt (l ^ 2 + h ^ 2), qhov twg d yog kab pheeb ces kaum, l yog qhov dav, h yog qhov siab. ob leeg ua ntej thiab tom qab lub xam.
