Ua ntej lub projector, swb tau siv los ua cov khoom lag luam tseem ceeb hauv kev lag luam, thiab nws tau pom tias yog ib daim ntawv tshwj xeeb ntawm lub projector.Qhov tshwm sim ntawm lub tshuab swb hnub rov qab mus rau 1640 AD, lub sijhawm ntawd, ib tug pov thawj Jesuit tau tsim ib daim slide hu ua khawv koob. teeb, siv lub lens thiab daim iav qhia txog lub hauv paus ntsiab lus ntawm lub teeb, cov duab ntawm cov duab tau tshwm sim rau ntawm phab ntsa, ua rau muaj kev xav, tab sis nws yog vim qhov kev tsim kho, nws raug liam tias yog khawv koob, nyiam kev tua neeg, thiab raug xa mus rau "guillotine".
Chiser txoj kev tuag, txawm li cas los xij, tsis cuam tshuam kev nrhiav cov cuab yeej tshiab,thiab German Jewish Kischal thawj zaug tau piav qhia txog kev tsim lub tshuab swb hauv xyoo 1645.Lub plhaub qub ntawm cov swb yog hlau rau hauv lub thawv square, sab saum toj ntawm cov pa luam yeeb lub tog raj kheej zoo ib yam li lub tog raj kheej, nyob rau hauv pem hauv ntej ntawm lub tog raj kheej, lub tog raj kheej nrog lub tog raj kheej. zawv zawg convex lens, tsim ib lub lens yooj yim, muaj ib lub vaj huam sib luag ntawm kev hloov kho focal nrug ntawm lub lens thiab lub thawv hlau, lub thawv muaj lub teeb ci, lub teeb ci qub yog tswm ciab.Thaum siv, lub tshuab swb yog muab tso rau hauv chav dub. , tus swb mus rau hauv lub qhov nyob tom qab lub convex lens, teeb lub tswm ciab, lub teeb qhov chaw los ntawm daim iav reflection convergence, los ntawm cov pob tshab daim duab thiab lens, tsim ib lub teeb kem reflected ntawm phab ntsa screen.
Nyob rau hauv 1845, nrog rau cov booming ntawm lub Industrial Revolution, swb cov cav tov kuj nkag mus rau hauv lub era ntawm industrial ntau lawm, lub teeb qhov chaw kuj hloov los ntawm yav dhau los tswm ciab rau roj teeb, chav teeb, thiab thaum kawg pib siv hluav taws xob qhov chaw.
Cov slides ntxov tshaj plaws yog ua los ntawm iav, los ntawm phau ntawv tha xim, thiab los ntawm nruab nrab-19th caug xyoo, tom qab cov neeg Amelikas tau tsim cov yeeb yaj kiab celluloid, cov slides tau tsim los ntawm kev siv yees duab hloov. nyob rau hauv lub hauv paus ntawm lub xyoo pua puv 19 tshuab swb.
Tom qab Tsov Rog Thoob Ntiaj Teb thib 2, kev tsim cov khoos phis tawj, qhov tshwm sim loj ntawm kev sib xyaw ua ke thiab kev tsim kho thiab kev siv dav dav ntawm cov thev naus laus zis tshiab tau coj lub projector mus rau hauv lub sijhawm digital.Lub projector thawj zaug siv CRT thev naus laus zis, kev qhia ntxov thiab TV teeb yog CRT thev naus laus zis. , lawv lub ntsiab feature yog qhov loj loj.Tom qab ntawd, LCD technology tau tshwm sim, thiab kev loj hlob ntawm LCD technology kuj ua rau CRT pib los ua keeb kwm.
Xyoo 1968, GHHeilmeier, tus kws tshawb fawb Asmeskas ntawm RCA Corporation, tau ua cov kua siv lead ua kua rau hauv LCD raws li cov txiaj ntsig dynamic tawg, tsim cov qauv ntawm LCD kev lag luam, tab sis nws yeej tsis commoditized thev naus laus zis.Nws tsis yog txog 1973 uas Japanese Sharp ua tiav. tsim lub tshuab xam zauv thiab saib nrog LCD thev naus laus zis ua vaj huam sib luag zaub, thiab coj ntau lub tuam txhab xws li Hitachi, NEC thiab Toshiba los koom nrog cov khoom lag luam LCD tsim thiab qib ntau lawm.
Siv lub tshuab LCD rau cov cuab yeej projection yog Epson, uas siv cov kua siv lead ua kua los hloov cov txheej txheem raws li qhov kev txiav txim ntawm cov electrodes kom lub teeb ci los ntawm LCD nti tuaj yeem tsim cov duab los ntawm lub lens.Txawm tias yog cov thev naus laus zis tshiab ntawm lub sijhawm, Lub LCD projector tseem muaj kev ua tau zoo thiab xim tsis xws luag raws li cov qauv monolithic, nrog rau ob qho tib si tsis tshua muaj nqi qhib thiab daws teeb meem.Nws tsis yog txog xyoo 1995 uas ib leeg-daim LCD projectors tau raug muab tso rau hauv kev ua lag luam, ua raws li lwm yam 3LCD technology hauv 1996, Nrog kev ua tiav hauv kev ruaj ntseg thiab xim kev ua tau zoo.Sony koom nrog tsim LCD chips, tab sis tshaj tawm xyoo 2004 tias nws yuav tsum tsis txhob muab nws cov LCD chips rau kev siv sab hauv nkaus xwb.Txog tam sim no, LCD projection technology yog monopolized los ntawm Epson thiab Sony.
Xyoo 1987, Dr. Larry Hornbeck tau tsim thawj lub cuab yeej DMD.Los ntawm 1996, cov ntaub ntawv kho qhov muag ua DLP thev naus laus zis tau ua lag luam rau kev lag luam kev lag luam, thiab thawj DLP projector tau pib, tsuas yog xya xyoo tom qab LCD projector.
Thawj DLP nti muaj cov qauv kev daws teeb meem ntawm 16 * 16, thaum lub sijhawm DLP projector thaum ntxov tsuas muaj 300 lumens, txhais tau tias nws tsuas yog pom hauv qhov tsaus ntuj. Txawm li cas los xij, ob txoj kev lag luam sib txawv ntawm DLP thev naus laus zis tau ua lub luag haujlwm zoo hauv kev coj ua. nws txoj kev txhim kho thev naus laus zis, thiab tau nyob hauv kev lag luam sai sai, coj ntau lub siab rau LCD projection technology.
DLP projector nyob rau hauv lub lag luam thaum ntxov nrog qhov kom zoo dua, los ntawm 1997 tsuas yog hnyav 6 phaus InFocus LP420 rau 2005 Samsung lub hnab tshos projector, DLP projector txuas ntxiv tso tawm tshiab tshiab lub tswv yim ntawm "portable", swept lub lag luam kev lag luam nrog xav tau mobile, yog li tau txais. ib tug foothold nyob rau hauv kev ua lag luam, thiab nyob rau hauv 2006 nyob rau hauv lub ntiaj teb no kev ua lag luam yeej tshaj 20% kev ua lag luam qhia, nrog LCD technology.Ntxiv rau, peb-daim DLP projector tau siv rau high-end engineering thiab xinesmas tej yaam num, ua rau cov kev tsis sib haum. nyob rau hauv kev daws teeb meem siab thiab ruaj khov siab uas LCD projectors tsis tuaj yeem daws tau yav dhau los.
Txawm hais tias DLP thev naus laus zis ntau dua, LCD thev naus laus zis tuaj yeem tswj tau ntau dua hauv cov khoom lag luam, tus nqi, piv nrog DLP, thiab lwm yam thev naus laus zis ntau dua, tus nqi tswj tau ntau dua, kev ua haujlwm ruaj khov dua, cov peev txheej ntawm daim ntawv thov, tshwj xeeb tshaj yog tom qab kev sib kis. era, yuav dav dhau los ua cov khoom siv hluav taws xob nrov dua hauv qee lub sijhawm.
