Yuav ua li cas yog cov sib txawv ntawm cov saib?

Saib xyuas - ib tug tseem ceeb ntawm tej computer system. Nws yog ib lub ntaus ntawv los ntawm qhov uas cov computer qhia ib tug neeg lub txiaj ntsim ntawm nws ua hauj lwm. Yog hais tias siv ib tug nas thiab keyboard, tus neeg siv theem cov nqaij nyoos cov ntaub ntawv, los ntawm cov duab nyob rau hauv monitor screen computer qhia qhov tshwm sim ntawm lawv suav.
Xws li yog qhov zoo ntawm kev sib tham. Nyob rau hauv sib piv rau lub me me nrog lub Cheebtsam, ntaus ntawv no yog tsis yooj yim sua tsis tau daim ntawv ceeb toom, yog li lub tswv yim xwb ntawm nws yog nyob rau txhua leej txhua tus. Nrog rau qhov no tsab xov xwm peb ntxiv cov kev paub txog lub hauv paus, ib tug los ze zog saib hom saib.

Nyob ntawm seb lub hom siv screen tag nrho xws li zaub pab kiag li lawm yuav tsum tau muab faib ua ob pawg loj - cov niaj hnub kua-siv lead ua (LCD, TFT, LCD), thiab yuav luag muab tshem tawm los ntawm loj lawm, cathode-ray (CRT, CRT). Tej zaum daim ntawv teev cov complementary peb zoo - LCDs, tab sis nws tseem zoo nkauj tej kev daws teeb meem yog tsis raws nraim ntau. Yog li, thaum koj kawm hom saib yog tas rau LCD thiab CRT.

Yeej, muaj ntau yam tseem nco ntsoov yuav ua li cas televisions saib mus rau thaum pib ntawm lub "era ntawm cov kua siv lead ua." Lawv heev loj heev ntaus ntawv, cov kev tshuaj ntsuam uas nyob deb ntawm zoo meej tus. Txawm tias nyob rau hauv xyoo tsis ntev los qhov teeb meem no nyob rau hauv no hwm tau hloov markedly. Leej twg tau muaj lub sij hawm los saib sab hauv lub cev CRT TV, paub hais tias yuav luag tag nrho cov ntim nyob los ntawm cov ib cathode txoj sab ci raj, thiab qhov luaj li cas ntawm cov kev tswj board tsis tshua zoo tshaj toj roob hauv pes cheeb tsam ntawm daim ntawv. Cov kev twb kev txuas ntawm lub monitor thiab lub TV nws tus kheej: lawv siv tib lub operating hauv paus ntsiab lus. Ntawm cov hoob kawm, nyob rau hauv tib ntau lawm tshuab.

Xav lub hom saib uas yuav tsis tau ignored nta ntawm qhov no los yog hais tias kev txiav txim siab. Yog li, peb sau qhov zoo ntawm CRT saib :

- yuav luag zoo tagnrho hloov lwm lub tsev ntawm tag nrho cov xim, txawm lub nkag teb chaws theem qauv nyob rau hauv no hwm yog nyob deb ua ntej ntawm lub kim LCD saib;

- cov tsis muaj saib cov ces kaum - daim duab ntawm qhov screen yog ib txwm pom, tsis muaj teeb meem yuav ua li cas nws ntog rau hauv txoj kab ntawm pom;

- tuag pixels, nplawm thoob plaws lub kua siv lead ua technology, ib tug CRT yuav tsis tau ua qauv;

- muaj tsis muaj teeb meem nrog lubrication cov duab thaum displaying ceev.

Tab sis LCD saib khav views ntawm sib txawv heev yam ntxwv:

- tsawg theem ntawm mains hwj chim, tus ib txwm muaj nqis yog 40 W (piv 80 thiab ib tug CRT);

- compact qhov ntev thiab tsis muaj qhov hnyav, thiab yog li ntawd mus rau qhov chaw xws li ib tug ntaus ntawv rau ntawm phab ntsa, tsis muaj yuav tsum tau nruab tua ncua kev kawm ntawv tus qauv;

- tshuam me me load rau hauv lub qhov muag: qhov tsawg kawg nkaus system illumination flicker zaus yog nyob rau hauv cov pua pua ntawm megahertz (contrary stereotype tsim, vim hais tias ntawm lub xub ntiag ntawm PWM kev cai, nws yog tseem muaj);

- zoo tagnrho cov duab clarity thiab lub tsis tuaj kawm ntawv ntawm cov teeb meem nrog nws kab teeb ntawm ib tug taw tes, raws li zoo raws li lub cev tsis distortion geometry.

Lub LCD saib muaj ib tug xov tooj ntawm cov nta uas yog tsis tuaj kawm ntawv nyob rau hauv lub CRT. Qhov no yog vim lub tsis tshua muaj neeg ntau kis nyob rau hauv technology. Piv txwv li, lub nram qab no ntawm matrices saib: Lub feem ntau TN, advanced IPS, ntau yam kev hloov kho ntawm lub VA. Txhua yam ntawm lawv tau tsuas yog nws xam qhovkev nta uas yog ib qho tseem ceeb yuav tau xav txog thaum yuav khoom ib tug LCD saib.
