1, STN LCD npo

STN yog ib lub ntsiab lus rau "Super Teisted Nematic", Nws belongs rau passive passive matrix LCD, yuav luag tag nrho cov xim dub thiab dawb vijtsam LCD yog hom khoom no. Xim STN LCD npo yog monochromatic STN LCD npo raws li xim lim, thiab txhua pixel hauv cov duab monochromatic matrix faib ua 3 daim duab pixels, thiab peb xim liab, xim ntsuab thiab xiav cov duab tso tawm los ntawm cov ntxaij lim dej kom tau cov duab xim. Vim tias cov kev siv technology ntau tshaj, lub siab tshaj plaws STN LCD npo tsuas yog 65536 xim, thiab lawv feem ntau yog 4096 xim STN cov khoom nyob rau hauv kev ua lag luam, ces STN tseem hu ua "fake color".


2, GF LCD npo

GF yog lub npe ntawm "Ij Zoo Xim", tej zaum txhua tus neeg yog coj txawv txawv rau GF LCD npo, vim hais tias GF LCD npo cov khoom muaj qis me me nyob rau hauv kev ua lag luam. Qhov tseeb, GF yog ib hom STN. Lub ntsiab ntawm GF lub ntsiab yog tias qhov ci ntsa iab khees me ntsis lawm ntawm qhov tsis muaj hwj chim txaus, tab sis GF LCD npo yog xim me ntsis.

3, TFT LCD

TFT yog lub npe ntawm "Thin Film Transistor", hu ua "tseeb xim". Nws yog rau matrix LCD npo. Nws yog ib qho screen uas thin film transistors. Txhua pixel taw tes ntawm nws cov kua siv lead ua yog tsav los ntawm ib zaj duab xis nyias transistor. Txhua lub pixel muaj plaub ywj pheej nyias zaj duab xis transistors tsav lub teeb xim tom qab txhua pixel. Nws tuaj yeem tso saib qhov tseeb ntawm 24 xim xim tob. Nyob rau hauv cov nqe lus ntawm kev daws teeb meem, qhov siab tshaj plaws TFT LCD tau ncav cuag UXGA (1600 x 1200).


Qhov kev npaj ntawm TFT muaj kev nco, yog li qhov tam sim no yuav tsis muab txum tim rov qab tam sim tom qab tam sim no disappearing, yog li kev txhim kho qhov muag dig muag thiab plooj ntawm STN LCD npo, kev txhim kho cov nyhuv ntawm cov duab ntawm daim duab duab hauv LCD npo, thiab lub peev xwm los tso saib daim duab zoo nkauj tshaj plaws, thiab Dragon Point ntawm TFT kua siv lead ua screen yog luv dua lub sij hawm teb. Thiab muaj xim zoo nkauj, yog li nws yog siv rau hauv cov phau ntawv sau cov computers thiab DV, DC. Lub drawback ntawm TFT LCD yog tias nws nqi ntau tshaj hluav taws xob thiab cov nqi ntau dua.


4, TFD LCD npo

TFD yog lub npe ntawm "Thin Film Diode", vim tias TFT LCD npo noj siab, thiab tus nqi siab, yog li ua tau nce tus nqi ntawm cov khoom, yog li EPSON qhia tshwj xeeb uas tsim TFD technology rau txawb xov tooj. Nws kuj yog rau matrix LCD npo, txhua pixel ntawm LCD yog nruab nrog ib qho diode nkaus xwb. Txhua pixel yog tswj ib tus zuj zus kom txhua pixel tsis txhob sib cuam tshuam nrog txhua lwm yam. Qhov no tuaj yeem ua kom zoo dua qub, thiab nthuav tau cov duab zoo nkauj thiab cov yeeb yuj xim tsis muaj kev sib tw.

Nyob rau hauv cov nqe lus ntawm kev ua tau zoo, lub TFD LCD screen muaj qhov zoo ntawm TFT LCD npo thiab STN LCD screen. Lub TFD LCD npo tseem ci tshaj qhov STN LCD npo, thiab xim zoo zog. Tib lub sijhawm, lub vijtsam LCD siv hluav taws xob ntau tshaj li lub TFT LCD npo, tabsis cov xim thiab ci ntsa iab tseem tsawg tshaj li ntawm TFT LCD npo.
