Apr 23, 2018
Ib qho tseem ceeb tshaj plaws hauv LCD yog ci ntsa iab. Qhov tseem ceeb tshaj plaws hauv kev txiav txim siab txog kev ci ntsa iab yog qhov kev sib txuas lus qhib. Tus aperture piv yog dab tsi?
Lub
Hauv cov ntsiab lus yooj yooj yim, qhov no yog qhov feem ntawm qhov cheeb tsam zoo uas dhau los ntawm lub teeb uas sib kis tau. Ntawm sab laug ntawm daim duab hauv qab no yog ib daim duab thaiv ntawm cov kua siv lead ua kua uas pom los saum toj lossis hauv qab. Thaum lub teeb tau tawm ntawm nws lub teeb, nws tsis yog tag nrho lub teeb yuav dhau los ntawm lub vaj huam sib luag. Piv txwv li, cov teeb liab siv los siv tsav tsheb qhov chaw tsav tsheb thiab lub rooj tsav npav thiab TFT nws tus kheej, nrog rau qee qhov kev siv cov khoom siv hluav taws xob cia, thiab lwm yam ntxiv, nrog rau kev sib kis tsis tiav, cov chaw no feem ntau Tus lub teeb kis tau los ntawm cov chaw no yuav tsis raug tswj los ntawm cov twj hluav taws xob thiab tuaj yeem tsis pom cov nplai grey. Yog li, nws yog ib qho tsim nyog yuav tau siv ib qho thaiv nris los tiv thaiv lub teeb kom tsis txhob cuam tshuam nrog qhov tseeb ntawm qhov chaw qee qhov chaw sib kis. Yog li ntawd, nws yog qhov zoo. Qhov chaw sib kis tau qes tsuas yog nyob rau thaj tsam ntawm sab xis ntawm daim duab. Qhov sib piv ntawm qhov chaw pom kev zoo thiab lub cheeb tsam tag nrho yog hu ua aperture ratio.
Lub
Thaum lub teeb tawm ntawm lub nrig qaum, nws kis tau los ntawm cov roj ntsha, iav, cov kua pleev kua, cov xim lim, thiab lwm yam. Peb xav tias qhov nkag mus ntawm txhua feem raws li qhia hauv qab no.
Lub
Polarizing phom nkag mus: 50% (vim tias nws tsuas yog pub kom dhau mus lub teeb tsis muaj lub teeb nyob rau hauv ib qho kev coj):
Lub
Iav allergic rate: 95% (qhov no yuav tsum xam lub sab saud thiab qis ob daim iav);
Cov kua siv lead ua kua dej: 95%; aperture ratio: 50% (zoo qhov chaw sib kis tau zoo tsuas yog ib nrab xwb);
Cov xim xim: 27 feem pua (Peb xav tias cov khoom siv ntawm tus kheej yog 80%, tab sis vim lub lim nws tus kheej yog coated nrog rau xim, nws tuaj yeem tsuas tso tau cov lus ntawm lub teeb tsis muaj qhov xim ntawm RGB no. ib qho ntawm peb hom no tau tso cai kom dhau, tawm hauv qhov tsuas yog 1/3 ntawm qhov ci ntsa iab, ces tag nrho tsuas yog 80% x 33% = 27% tuaj yeem dhau.
Lub
Yog hais tias koj siv cov nqi saum toj no nkag mus, ces tsuas yog 6% ntawm lub teeb ntawm lub teeb nruab nrig yuav sab laug, uas yog tiag tiag tsis zoo, uas yog vim li cas nyob rau hauv kev tsim ntawm TFT LCD npo sim Sim Qhov tseem ceeb vim li cas rau nce lub aperture piv tau yog tias ntev npaum li lub qhov qhib qhov ntxiv, qhov ci yuav nce siab ntxiv. Nyob rau tib lub sij hawm, qhov ci ntsa iab ntawm lub teeb rooj teeb meem tsis siab li, thiab kev siv hluav taws xob thiab nqi yuav raug cawm dim tau.
