Tam sim no, kom muaj lub khoos phis tawm hauv koj lub tsev yog yuav luag qhov khoom siv uas yuav tsum tau muaj. Hauv qhov no, muaj qhov teeb meem no ua rau muaj kev noj qab haus huv txaus. Yog lawm, nws tsis yooj yim los sis nrawm los daws qhov teeb meem no kom tag. Tab sis kom tawm tsam nws tam sim no tsis yog tsuas yog ua tau, tab sis kuj tsim nyog.

Nws yog qhov tsim nyog

Ua ntej xaiv cov ntsuas tshwj xeeb, kawm ntau ntxiv txog nws lub zog

Cov Lus Qhia

Kauj ruam 1

CRT - saib xyuas lossis thawj tiam ntawm tus saib.

Lub tshuab raj cathode-txoj sab ci ua haujlwm ua lub hauv paus ntawm kinescope. Lub raj xa duab yog ib qho khoom siv hluav taws xob uas hloov cov hluav taws xob cov hluav taws xob rau hauv cov duab pom. Cias tso, peb pom cov duab ntawm CRT saib siv lub raj tshwj xeeb. Lub teeb kis tau los ntawm txoj raj no, tom qab ntawd nws tsoo rau ib qho kev cuam tshuam, thiab tom qab ntawd mam ua kom pom ib qho duab.

Cov ntsuas no loj, hnyav, thiab siv ntau lub zog. Thiab tseem, lawv cuam tshuam zoo rau kev pom kev los ntawm kev siv hluav taws xob hluav taws xob. Uas kis tau tom qab thiab ntawm ob sab ntawm tus saib ntawm qhov deb ntawm 1.5 m. Thaum siv, qhov tshwm sim xws li "flickering" feem ntau tshwm sim, uas ua rau txo qis ntawm qhov pom tseeb. Cov saib no tam sim no tawm ntawm ntau lawm, tab sis koj tuaj yeem yuav cov siv siv. Thiab txawm hais tias koj yuav siv nyiaj txog $ 50, xws li lub monitor yuav ua rau muaj kev phom sij rau koj lub cev.

LED - saib xyuas.

Cov neeg soj ntsuam siv cov LEDs siv hloov cov teeb roj taws. Lawv yog lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov ntsuas no. Cov no yog cov lub teeb me me, ua tsaug uas peb pom daim duab ntawm lub vijtsam. Cov LED tsim cov qauv siv lead ua dawb thiab xim dub rau txhim kho kev sib piv, pom meej thiab ci. Cov xim zoo li ntau dua rau ib tus neeg, yog li ua rau nws muaj kev ntseeg ntau dua.

Cov saib no haus yuav luag 50% tsawg zog dua li CRTs. Lawv tus nqi kuj tseem ntxim nyiam - txij li $ 100. Lawv yooj yim rau siv, tsis txhob coj mus rau ntau qhov chaw thiab kev xyaum tsis cuam tshuam lub zeem muag. Tsis muaj mercury nyob hauv kev tsim khoom, uas yog qhov txiaj ntsig ib puag ncig.

Saib LCD.

Cov ntxaij ua kua siv lead ua yog tsim los ntawm cov khoom siv cyanophenyl, uas yog nyob rau hauv lub xeev ua kua, tab sis khaws cov khoom ntawm cov khoom muaju ntawm cov khoom muaju, vim li no lub npe. Niaj hnub no cov no yog cov neeg saib xyuas tas li.

Cov saib pom ua haujlwm ntawm lub hauv paus ntawm cov kua siv lead ua kua. Thaum lub teeb liab tau muab, lawv hloov kho lub teeb ntawm qhov screen, yog li muab ib cov duab.

Tus nqi nyob ntawm cov kab pheeb ces kaum, tab sis nyob rau nruab nrab ntawm $ 80. Vim nws cov qauv yooj yim, tsis muaj hluav taws xob hluav taws xob thiab tus nqi tsim nyog, tus saib LCD kov yeej lub ntiaj teb.

Nws hloov tawm tias LCD saib yog qhov kev nyab xeeb tshaj plaws ntawm saib. Tab sis, hmoov tsis zoo, txawm tias nrog nws, koj tuaj yeem lwj qhov muag yog tias koj tsis ua raws txoj cai rau kev ua haujlwm ntawm lub koos pis tawj:

- cov ntsuas yuav tsum tau nruab ntawm qhov deb ntawm tsawg kawg 50 cm ntawm koj tus kheej, ntawm qib muag;

- ntxiv rau qhov tseem ceeb lub teeb pom kev zoo, nce mus rau ntxiv;

- zam qhov muab rov los saib dua;

- txhua txhua teev ntawm kev ua haujlwm ntawm lub khoos phis tawm, cuam tshuam los ntawm 15 feeb los ua kev ua si kom lub qhov muag.
