Kev txhais ntawm cov ntsiab lus tseem ceeb ntawm LCD npo

1.tft - LCD

Rau cov ntxaij vab tshaus feem ntau siv, TFT: LCD feem ntau yog sau ua ntej thawj yam hauv phau ntawv tshwj xeeb.

TFT (nyias zaj duab xis transistor) yog ib zaj yeeb yaj kiab nyias nyias compender trantor. Lub yog - hu ua nyias zaj duab xis trentor txhais tau tias txhua ua kua Crystal pixel rau ntawm cov duab ua kua crystal los ntawm ib zaj duab xis clistor nyias nyias. Qhov no ua rau muaj kev kub siab - ceev, siab - ci, thiab siab - sib piv cov ntaub ntawv ntawm cov ntaub ntawv tshuaj ntsuam.

Tft yog ib qho kev nquag ua haujlwm matrix ua kua siv lead ua kua, thiab tft - lcd ua kua crystal zaub yog "xim tseeb" (tft).

2. Brightness
 

Brightness hais txog yuav ua li cas qaim daim duab yog. LCD muaj lub backlight, uas yog tsim los ntawm lub teeb - emitting diodes txuas nrog hauv series thiab parallel. Lub ci ci ntawm lub teeb - emitting diode feem ntau qhia nyob rau hauv cov nqe lus ntawm luminous siv (luminous siv), thiab chav tsev yog cdela cd, 1000UCD (microcandela) = 1 MCD (Millicandela).

Qhov ntau dua qhov ci, qhov zoo dua. Ntau dua ci ntsa iab feem ntau ua rau tib neeg tsis xis nyob. Ntawm ib sab tes, nws yooj yim ua rau kev pom kev nkees. Nws tseem yuav txo qhov sib txawv ntawm cov dawb ntshiab thiab dub dub, cuam ​​tshuam rau kev ua tau zoo ntawm cov xim thiab cov nplai grey. Yog li ntawd, thaum nce qhov ci ci, qhov sib piv yuav tsum tau nce, Txwv tsis pub tag nrho cov zaub yuav tshwm sim dawb.

3. Pixel

Daim duab peb pom yog tsim los ntawm ntau cov me me, uas peb hu rau pixels, kuj tau hu ua pixels.

Nyob rau hauv tib lub cev lub cev, cov pixels ntau, lub meej dua cov duab tso tawm, thiab tsawg dua pixels, lub plooj rau cov duab tso tawm. Piv txwv li, yog tias daim duab duab muaj 20 lab pixels, txawm tias cov ncej yuav pom kom pom tseeb. Yog tias muaj tsuas yog 1 lab pixels, lub qhov ntswg thiab lub qhov muag yuav ua plooj. Qhov no yog li cas tus naj npawb ntawm cov pixels yog siv los piav txog qhov tseeb ntawm daim duab. degree.

Qhov ntau pixels ib teev lub cev lub cev, lub siab dua lub ntsiab txhais.

4. Pixels H x V

Cov kev daws teeb meem feem ntau tau piav qhia raws li m sawv cev ntawm tus naj npawb ntawm kab rov tav pixels hauv kab rov tav kev, thiab n sawv cev tus naj npawb ntawm ntsug pixels hauv cov kev taw qhia ntsug. Qhov sib npaug ntawm ob yog tag nrho cov pixels hauv daim duab.

Piv txwv li, ib daim duab nrog kev daws teeb meem ntawm xyoo 1920 kom muab tso rau nws bluntly, daws teeb meem tseem qhia txog tag nrho cov pixels hauv ib qho duab,

Nws tsuas yog cov lus piav qhia sib txawv.

5. Xim Qhov tob

Xim tob yog xim tob. Xim xim tsis xa mus rau pes tsawg cov xim nws npog, tab sis muaj pes tsawg tus gripayscales (uas tuaj yeem nkag siab tsuas yog ci ci ntawm xim) tib xim muaj. Nyob rau hauv lub ntiaj teb ntawm xim tob, "txhua xim" txhua xim tsis yog ib xim xwb. "Vim tias txhua tus xim muaj ntau grayscales, chav tsev me ntsis.

Piv txwv li, yog tias muaj 8 - bit zaub screen muaj ib qho channel, tom qab ntawd txhua txhua lub teeb xim channel yog sawv cev los ntawm 8 yam. Qhov ntawd yog, muab peb 2 mus rau 8th fais fab sib npaug 2 mus rau lub zog 24, uas yog peb tau hais dab tsi. Qhov "muaj tseeb xim tob" muaj tag nrho cov xim tag nrho ntawm 16.7m xim. Tus qauv no yuav luag tau los ntawm cov neeg saib xyuas cov cuab yeej tam sim no.
