Kev xaiv ntawm cov chaw tsim khoom tsis yog qhov kim dua qhov zoo dua, tab sis xaiv cov khoom koj tus kheej raws li koj cov kev xav tau thiab muab koj cov kev paub zoo tshaj plaws. Hauv qab no piav qhia txog yuav ua li cas xaiv cov zaub tsim kev lag luam zoo tshaj from lub zeem muag ntawm backlight lub neej, txias cathode fluorescence, xim, thiab lwm yam.

　　 Thawj yog qhov backlight lub neej txias cathode fluorescence (CCF). Hauv cov ntawv thov kev lag luam, lub neej ntawm CCF lub teeb pom kev zoo feem ntau yog 50,000 teev, lossis qhov ci ci tsawg dua ib nrab piv nrog cov tshiab. Hauv kev siv ntau tus neeg siv khoom, nws only yuav siv sij hawm 10,000 teev rau qhov ci ntawm lub backlight los poob rau ib nrab ntawm nws qhov pib ci. Vim tias cov neeg siv cov ntawv thov tsis xav tau cov zaub txuas ntxiv mus ua haujlwm, lub neej ntawm CCF lub teeb pom kev hauv 10,000 teev yog qhov txaus, tab sis qhov no tsis yog qhov xwm txheej hauv feem ntau cov kev lag luam thiab kev kho mob. Piv nrog LCD, kev pab lub neej ntawm lub backlight yog luv heev. Cov neeg ua haujlwm sib zog ua kom tau ob lub neej kev pabcuam ntawm lub backlight, tab sis nyob rau hauv feem ntau cov ntawv thov kev lag luam, kev pabcuam kev ua haujlwm tsawg kawg nkaus ntawm 5000 teev yog suav tias yog kev pabcuam kev ua neej nyob ntawm CCF backlight

　　Thib ob, hauv cov khoom siv ua kua siv ua kua pom, cov xim sib xyaw xim nyob ntawm tus cwj pwm ntawm lub teeb nrig rov qab. CCF (Cold Cathode Fluorescent Screen) rov qab lub teeb ci yog lub thev naus laus zis zoo tshaj plaws uas tuaj yeem ncav cuag 70% thiab 80% ntawm NTSC xim saturation.

Twg cov zaub kev lag luam zoo dua?

　　 Thib peb, hauv kev tsim vaj huam sib luag, qhov kev hloov no yuav tshwm sim txhua tsib xyoo lossis ntau dua. Kev hloov tshwm sim vim tias nws yuav tsum yoog rau kev nce qib thev naus laus zis los yog muaj cov qauv tsim tau zoo. Yog li no, thaum tsim cov khoom siv kho mob thiab khoom siv kho mob, nws yog qhov tseem ceeb heev rau tswj hwm qee qhov kev kawm txuas ntxiv, suav nrog tib lub qhov sib dhos, cov haujlwm txuas, thiab txawm tias qee qhov kev ntsuas zoo ib yam. Thaum cov zaub hloov pauv hauv tsib xyoos, qhov khoom kawg tuaj yeem muaj lub neej ua haujlwm 10 xyoo. Ua ntej xaiv cov ntsuas, nws pab ua tib zoo xav txog qee cov qauv thiab kev qhia, nrog rau lub tuam txhab cov tswv yim tsim. Hauv kev sib piv, cov neeg siv khoom tuaj yeem hloov kho txhua 6 lub hlis, uas ua rau lawv nyuaj rau siv hauv kev siv uas yuav tsum tau tswj kev teeb tsa.

　　Ua ntej xaiv cov zaub lag luam, koj yuav tsum xav txog qee cov qauv kev teeb tsa thiab cov tuam txhab kev tsim qauv, thiab xaiv cov khoom lag luam tsim nyog tshaj plaws.
