Paub meej LCD technology
LCD kua siv lead ua yog ib yam khoom nruab nrab ntawm cov kua thiab cov khoom, los ntawm kev hloov pauv kub kom ua tiav cov txheej txheem sib txawv ntawm cov kua siv lead ua kua molecules, yog li tsim cov qib grey sib txawv thiab cov duab sib txawv. Lub tshuab LCD tam sim no feem ntau muab faib ua ib-chip LCD thiab peb-chip LCD projectors. Monolithic LCD thev naus laus zis suav nrog peb lub ntsiab xim liab, ntsuab thiab xiav ntawm ib lub vaj huam sib luag LCD, thaum 3LCD thev naus laus zis faib cov xim liab, ntsuab thiab xiav rau hauv peb lub LCD vaj huam sib luag. Los ntawm cov kev taw qhia ntawm kev pom, tam sim no ib leeg-chip LCD thev naus laus zis tau raug tshem tawm tragically, thaum peb-chip LCD txuas ntxiv siv, tab sis maj mam ua rau niche.
DLP technology qhia ntxaws
Los ntawm cov piv txwv hauv qab no, peb tuaj yeem pom meej tias lub hauv paus ntsiab lus ntawm DLP yog raws li hauv qab no:
Lub teeb-condenser lens-xim log-lens-DMD nti-projection magnifying iav-screen
Txhawm rau ua qhov piv txwv yooj yim, DMD nti zoo li siv lub teeb nyem hloov mus rau lub teeb liab, tab sis DMD yog iav ntau, thiab nws hloov 3 xim. Ntawm qhov ceev ntawm ntau tshaj 60 zaug hauv ib ob, lub qhov muag tuaj yeem sib xyaw xim tom qab duab los ua xim. .
Ib qho-chip DMD yog tsim los ntawm ntau daim iav. Txhua daim iav micro sib raug rau ib pixel. Thaj tsam ntawm lub pixel yog 16μm × 16μm (qhov tshiab yog 14μm × 14μm). Lub cev daws teeb meem ntawm DLP projector yog txiav txim los ntawm tus naj npawb ntawm micromirrors.
Kev sib piv ntawm DLP technology thiab LCD technology
Feem ntau hais lus, cov xim saturation ntawm LCD projection yog zoo dua, tab sis cov duab stability ntawm DLP technology yog heev txhim khu kev qha. Vim tias DLP thev naus laus zis siv cov khoom siv tsis zoo, lub neej tso saib ntawm DMD chips tuaj yeem ncav cuag 100, 000 teev. Lub tshuab LCD siv cov kua siv lead ua kua, yog li kev siv mus ntev yuav ua rau cov duab tsis zoo.
Ntxiv rau, DLP thev naus laus zis muaj qhov sib piv zoo dua. Qhov kev kwv yees dav dav DLP tuaj yeem ncav cuag qhov sib piv ntawm 3000: 1, thaum lub LCD projection tsuas yog 800: 1. Qhov sib txawv no kuj ua rau LCD kev ua tau zoo nyob rau hauv qhov tsaus ntuj. . Ntawm tag nrho, DLP qhov projection nrog ntau dua kev lag luam sib koom thiab tsawg dua qhov tsis txaus ntseeg yog qhov tsim nyog yuav pib nrog.
