1, dab

Dab tsi yog hais txog qhov kev ntsuam xyuas tom qab hloov qhov kev tshuaj ntsuam yav dhau los yuav tsis tau sai sai maj mam tab sis tsis pom qhov tshwm sim ntawm plooj thiab lub sij hawm tshwm sim tsis zoo li qub, dab dab tsi yog ob lossis peb lub vib nas this yuav tag nrho ploj, thiab lub sijhawm ua kua yog kaum rau kaum ntawm milliseconds. Tus qauv tsim ntawm cov kua siv lead ua kua, txawm hais tias lub sij hawm ua rov qab yog 15 + 35ms, tsis tuaj yeem cia cov neeg siv pom qhov tom qab.

Tom qab cov txheej txheem me ntsis thiab feem ntau yog tib lub adsorption ntawm cov kua hluav taws xob uas muaj cov kua dej ion-siv ua kua dej ntev dhau lawm ntawm ob sab ntawm sab qaum thiab qis iav ua qhov kev tsim hluav taws xob, daim duab tom qab hloov cov ions no tam sim ntawd tso, lub kua siv lead ua kua molecules tsis tas yuav tsum tig mus rau lub kaum sab xis yuav tsum yog los ntawm. Lwm cov caij nyoog yog vim cov neeg pluag tsim ntawm cov pixel electrode, cov kua siv lead ua kua molecules nyob hauv lub xeev kev hloov kho tsis meej, qhov teeb meem no tseem tuaj yeem pom tom qab.

2, 点 ((dot defect)

Tus tuag hu ua hais txog cov kua qaub (crystal crystal display) yuav tswj tsis tau lub teeb ci lossis qhov teeb meem ntawm qhov tsaus ntuj nti yog tshwm sim los ntawm lub vaj huam sib luag LCD vim muaj ntau yam ua rau cov vaj huam sib luag, kev tswj hwm yuav tsis zoo thiab ua li ntawd. Pixels raug muab faib ua ob hom: kaj thiab tsaus. Feem ntau, ntau tshaj qhov tsaus nti tseem ceeb yuav tsis tsim nyog, ntau lub tuam txhab yuav xyuas kom meej tias tsis muaj cov ntsiab lus tseem ceeb, tab sis nws tsis pom zoo kom tsis muaj scotoma, ib txhia vaj huam sib luag manufacturers ua ntej cov zaub mov xa cov "scotoma.

Lub vaj huam sib luag manufacturers yuav muaj Huaidian lub rooj sib luag khoom muag, feem ntau tsis muaj pixels tuag A, Qib B yog qis tshaj li peb qhov qhab nia, rau cov ntsiab lus tsawg dua C li.

Muaj ntau lub tuam txhab muag ntawm lub khw tam sim no ua tiaj tiaj, nrog IPAD2, IPAD3, MINIPAD npo, thiab tom qab ntawd ces cov khoom siv dag siv coj los hais tias Apple, piv nrog cov kua, cov tuam txhab lag luam muaj kev lom zem heev. Qhov tseeb tiag, lawv siv cov tshuaj kua hauv cov txheej txheem tshuaj ntsuam xyuas tau zoo tshaj plaws, xws li apple A + A-screen, nrog A-hauv qab qib ntawm qhov screen, tag nrho rau hauv kev ua lag luam, cov ntsiav tshuaj yog khib nyiab, tab sis kuv tau ua tej no, qhov chaw tsis zoo.

3, mura

Mura yog Ameslikas cov lus Japanese, lub ntsiab lus tsis sib xws, nrog cov pob zeb, nrog Nyij Pooj lub LCD ua qauv rau pem hauv ntej thoob qab ntuj. Mura yog hais txog qhov kev ci ntsa iab ntawm cov duab tsis yog txhua yam ntawm kev tshwm sim ntawm qhov tshwm sim, qhov yooj yim tshaj yog txiav txim siab hauv qhov tsaus ntuj hloov mus rau lub vijtsam dub thiab lwm cov duab uas tsis tshuav xim, thiab los ntawm ntau cov ces kaum thiab pom, qhov teebmeem yog yooj yim pom cov duab.

4, Ncuav qab zib (xim gamut)

Xim xim yog hais txog cov xim ntawm cov xim, lub teeb liab yog xim ntsuab thiab xiav peb xim ntawm lub teeb rau txhua lub teeb xim, yog tias RGB xim muaj xim dawb, cov lus yuav hais tau cov xim ntau yog qhov dav.

5, Brightness

Brightness yog hais txog qhov ci ci ntawm cov zaub nyob rau hauv lub vijtsam dawb, chav tsev yog cd / m ^ 2, lossis nit. Luminance yog ib qho tseem ceeb uas cuam tshuam ncaj qha rau cov duab zoo. Nyob rau hauv kev kuaj, peb pheej hais ib lo lus: "ib qho kaj, npog peb npeeb." "Ib lub teeb pom kev zoo, txawm tias cov xim daj los yog xim daj thiab lwm yam kev mob, tseem tuaj yeem tshwm sim zoo nkauj dua.

Brightness muaj feem xyuam rau lub teeb, lub teeb muaj ib lub neej, tshwj xeeb tshaj yog CCFL yav dhau los, qhov ntev ntev yuav daj, qhov no yog tias lub tsev muaj cov qauv qub kuj yuav pom tseeb.

6, kev xav

Cov kua siv lead ua kua los ntawm lub cev ntawm lub cev, tso cai rau tus neeg siv pom los ntawm ntau cov ces kaum thaum daim duab zoo yuav hloov. Muab piv nrog menyuam, thaum lub siab xav pom, xav kom hloov cov duab zoo thaum nws txuas nrog lub sab xaav, hu ua qhov saib ntawm qhov khoom.

7, 色温 (xim kub):

Xim yog siv los piav qhia txog cov xim dawb, tsis tas rau LCD, tag nrho cov lus tseem ceeb, thaum cov duab xim thiab kub ntawm qhov kub siab rau qhov kub siab thaum lub teeb tawm hauv lub teeb zoo li, hu ua qhov tso xim kub yog sib npaug mus rau qhov kub thiab txias. Piv txwv li, thaum cov qauv tsim ntawm cov khoom nyob ze ntawm lub cev dub ntawm qhov kub ntawm 6500K, xim ntawm lub teeb (ze lub tshav ntuj thaum tshav ntuj) yog hu ua xim kub ntawm daim duab yog 6500K.

Cov xim kub qis dua xim tuaj yeem muaj xim daj, xim dua xim xim, xim muaj xim tshaj, xim dua kub xim hauv cov duab cov duab tag nrho cov xim xim yuav xiav.

8, Gamma Nkhaus:

Gamma nkhaus yog hais txog qhov kev sib raug zoo ntawm qhov nruab nrab ntawm qhov ntsuas grey thiab ci ntsa iab. Siv cov xoom rau 255 grey teev raws li X axis, qhov ci ntsa iab yog Y axis, thiab qhov twv raug twv yog hu ua gamma curve. Gamma nkhaus, feem ntau tsis yog ncaj nraim,

Vim hais tias tib neeg lub qhov muag muaj qhov sib txawv ntawm qhov qhia txog qhov sib txawv ntawm qhov sib txawv, piv txwv li, kev ua kom pom qhov qis qis qis qis dua (hloov me me ntsis zoo lawm).
