Yuav ua li cas yog tus zoo ntawm cov zaub?

Imperceptibly tuaj ib lub sij hawm thaum tus saib raws li nyob rau hauv cathode txoj sab ci hlab (CRT) tau kiag li zoo los ntawm hauv txee ntawm lub computer cov khoom khw, hloov los ntawm lawv cov LCD counterparts. Txawv nrog rau qhov no technology, cov neeg feem ntau tau tsis meej pem nyob rau hauv cov nqe lus ntawm, raws li muaj ob peb lub npe ntawm cov tib kawm. Yuav kom tsis txhob muaj kev kub ntxhov, wb cia li qhia ntxiv no: LCD, LCD - tag nrho ib tug thiab tib yam kua siv lead ua technology ntau dua li sib txawv. LCD txhais tau tias kua Crystal zaub. Kov, kuj no yuav tsum tau ntaus nqi rau lub sij hawm «TFT», txhais tau tias cov kev siv ntawm nyias zaj duab xis transistors los tswj lub matrix. Txij li thaum lawv tsis siv nyob rau hauv ib tug CRT, nws yog pom tseeb tias cov kev siv TFT thiab qhia rau cov LCD.

Hloov lub qub CRT saib uas niaj hnub LCD, ntau cov tswv yuav ntsib nrog cov tsab tshwm sim - tus thawj lub sij hawm tom qab qhov kev hloov yuav pib mob lub qhov muag, thiab ib txhia txawm blushing lub ntsej muag. Li no, tus ua raws-up lo lus nug - "Yuav ua li cas kuv saib xyuas teeb rau lub qhov muag." Lub Network muab ib tug xov tooj ntawm cov tswv yim, tiam sis feem ntau ntawm lawv yog cov tsis tiav, vim hais tias qhov ua rau ntawm dab tsi tshwm sim heev cleverly overlooked. Tseeb, yog hais tias tus saib zoo thiab brightness rau LCD thiab CRT technologies zoo xws li cov tswv yim, ces los ntawm tsis xis nyob rau hauv lub ob lub qhov muag thaum ua hauj lwm nrog LCD? Tom qab tag nrho, qhov no yuav tsum tsis txhob yuav. Qhov tseeb ua ntawm qhov muag qaug zog yog tias LCD saib flicker. Cov kev khiav hauj lwm hauv paus ntsiab lus ntawm lub fluorescent teeb illumination raws li nyob rau hauv cov roj ntswg nyob rau hauv lub raj, txawm nrog niaj hnub LED-teeb kuj xam qhovkev flickering (nyeem ntawm lub PWM tswj ntawm LEDs). Nyob rau hauv tas li ntawd, lub luminescence xim raws li lub teeb thiab diodes - unnatural, nws muaj puas spectrum. "Los ntawm lub qhov muag" yog invisible, tab sis lub nrig txog kev pom receptors tsis txhob yuav fooled.

Feem ntau, tus zoo ntawm tus saib - nws yog ib tug numeric nqi uas nruab nrab yog cov piv ntawm cov brightness sib txawv ntawm cov feem ntau kaj dawb taw tes rau lub tsaus ntuj tshaj plaws dub. Cov phau ntawv hla tebchaws cov ntaub ntawv teev nyob rau hauv daim ntawv ntawm «xxx: y» saib. Nyob rau hauv qhov tseeb, qhov no yog ib txoj kev sau ntawv. Piv txwv li, cov zaub zoo ntawm lub siab tshaj plaws luminance point ntawm 300 cd / m2 thiab ib tug tsawg kawg nkaus ntawm 0.5 cd / m2 yog (300-0.5) /0.5 = 599: 1. Nws yog ntseeg hais tias ntau dua qhov zoo nqi, lub sharper cov duab. Qhov no yog tej muaj tseeb, tiam sis tsuas yog mus rau ib tug tej yam kev txwv, raws li ib tug infinite nce ua rau yus ib tug distortion ntawm daim duab (lub teeb kom meej rau ib tug dawb keeb kwm yav dhau cease yuav distinguishable). Yog hais tias tus zoo ntawm tus saib yog tsis configured kom zoo, nws yog ib tug ntawm cov yog vim li cas rau cov kev xav ntawm cov xuab zeb nyob rau hauv lub ob lub qhov muag thaum koj hloov CRT rau LCD.

Nco ntsoov tias tag nrho cov kev npaj nyob rau hauv lub network configuration tsis yog subjective. Txhua tus neeg siv yuav tsum ua ib qho kev hloov, raws li thiaj tau tuaj rau tus kheej nyiam. Muaj yuav ua tau-nyob rau hauv qhov chaw kawm qhov ci ntawm lub monitor, uas tso cai rau optimum set tus nqi ntawm cov brightness thiab sib piv, thiab gamma nyob rau hauv lub qhov rais 7 operating system.

Nyob rau lub desktop, nias rau txoj kev nas khawm, raws li nyob rau hauv lub "Screen Resolution", tus "Ua ntawv nyeem thiab lwm yam khoom loj los yog me me" thiab "calibrating xim". By txhaj "Tom ntej", raws li cov tswv yim los ntawm tus tswv (no muaj ib tug ncauj lus kom ntxaws pab). Thaum kawg koj yuav yuav prompted rau configure cov zaub ntawm fonts rau lub Clear hom technology: nyob rau hauv qhov kev kuaj qhia tias cov feem ntau leej thiab "muaj roj" kab ntawm cov tsiaj ntawv.

Tsis tas li ntawd, koj yuav tau kho tus saib nws tus kheej. Yuav kom qhia tau zoo ib tus ntawm 20-40%, thiab tau high-quality luminance duab. Nyob rau hauv tej rooj plaub, lub ci ci yuav ua tau sib npaug zos rau zero, uas yog heev tau. Xim kub (sib txawv nyob rau hauv daj los yog xiav spectrum) yuav tsum tau teev nyob rau hauv lub hauv paus ntawm tus kheej nyiam. Nws yog tau hais tias yuav ntau yam daj zas coj mus rau cov xim kub ntawm tshav ntuj (6300 K). Ntau mechanisms los txhim kho cov duab thiab cov dynamic zoo piv tsis pub kom configure tus saib, ces nws yog tsim nyog los sib piv cov enhanced thiab lub ntuj hom thiab xaiv qhov zoo tshaj plaws rau koj tus kheej.
