LCD kua siv lead ua zaub npog tsib hom zaj duab xis.

1, TN zaj duab xis hom LCD LCD npo

Segment code LCD npo, yog LCD zaub hom, LCD npo muaj ob hom cwj mem so thiab dot-matrix, ntu code tseem hu ua tus cwj mem tawg ib tus lej yog tso tawm los ntawm 8 lo lus, 8 lo lus yog tsim los ntawm 7 tus cwj mem, tuaj yeem tso saib 0~9 tus lej xws li lub laij lej, moos, tso saib cov ntsiab lus yog digital.

Cov txheej txheem ntawm segmental-code LCD npo yog qhov yooj yim dua li ntawm dot matrix, tau kawg, nws tuaj yeem tso saib cov ntsiab lus yooj yim xwb. Cov cim Suav thiab cov duab ntawm segmental-code LCD npo tsuas tuaj yeem tso tawm kom pom nyob rau hauv cov qauv ruaj khov. Cov lej tuaj yeem hloov pauv, thiab txhua qhov kev qhia ntawm dot matrix tuaj yeem hloov pauv ntawm qhov xav tau.

2.HTN zaj duab xis LCD LCD npo

Txhais: hom twisted nematic heev; Feature sib piv yog siab, zog noj yog tsawg, tsav voltage yog tsawg.

Nematic kua siv lead ua molecules yog sandwiched ntawm ob lub iav pob tshab. Nruab nrab ntawm ob txheej iav, qhov taw qhia ntawm cov kua siv lead ua kua molecules yog deflected los ntawm 110 txog 130 degrees. Cov yam ntxwv ntawm hom LCD no yog qhov kev ua haujlwm ntawm kev tsav tsheb tsis zoo, tab sis lub kaum sab xis pom dav dua li TN hom.

3.STN zaj duab xis LCD npo

STN (Super Twisted Nematic) yog lub teb hluav taws xob uas hloov cov txheej txheem ntawm cov kua siv lead ua kua molecules twisted saum 180 degrees los hloov kho qhov muag hloov lub xeev. Daim ntawv thov hluav taws xob hloov pauv hluav taws xob los ntawm txoj kev ntawm kev soj ntsuam ua tiav. Nyob rau hauv tus txheej txheem ntawm lub teb hluav taws xob pheej hloov qhov voltage, cov txheej txheem rov qab ntawm txhua qhov taw tes yog qeeb, yog li ntawd lub afterglow yog generated. Nws muaj qhov zoo ntawm kev siv hluav taws xob tsawg, uas muaj qhov zoo tshaj plaws ntawm kev txuag hluav taws xob.

Lub hauv paus ntsiab lus ntawm cov xim STN yog ntxiv cov xim lim rau ntawm cov tsoos monochrome STN LCD, thiab faib txhua pixel hauv monochrome zaub matrix rau hauv peb lub pixel sub-pixels, raws li cov xim lim kom pom peb lub ntsiab xim liab, ntsuab thiab xiav, ces cov duab xim tuaj yeem tshwm. Sib txawv ntawm TFT, STN belongs rau Passive LCD, nrog lub peev xwm siab tshaj plaws ntawm 65536 hom

Xim.

Nws feem ntau muab faib ua STN, FSTN, CSTN thiab DSTN.

Ordinary STN yog cov kua siv lead ua rotating nyob rau hauv lub LCD npo 180 ~ 270 degrees, lub LCD npo yog pasted saum toj no thiab hauv qab cov polarizer zoo tib yam, vim yog vim li cas ntawm dispersion, lub LCD screen tom qab xim yuav qhia ib co xim, ntau daj ntsuab los yog xiav, uas feem ntau hu ua daj ntsuab pwm lossis xiav pwm.

FSTN (Film plus STN), txhawm rau txhim kho cov teeb meem xim tom qab ntawm STN zoo tib yam, txheej txheej ntawm cov nyiaj them poob haujlwm tau ntxiv rau cov polarizer, uas tuaj yeem tshem tawm qhov tawg thiab ua tiav cov duab dub thiab dawb.

CSTN (ColorSTN), xim STN, raws li FSTN thev naus laus zis, ntxiv ib txheej ntawm RGB xim zaj duab xis, xim zaub, feem ntau ntau dua ntawm kev tsav tsheb.

DSTN (DoubleSTN), ob txheej STN, ib txheej ntawm kev tsav tsheb, lwm txheej rau cov txheej txheem them nyiaj, belongs rau STN dub thiab dawb thev naus laus zis, piv nrog FSTN, qhov sib piv yog siab dua, thiab tuaj yeem them tus kheej nrog qhov kub thiab txias, kom ua tiav qhov kub ntau ntawm qhov sib txawv siab.

Lub hauv paus ntsiab lus ntawm STN hom zoo ib yam li TN, tab sis qhov txawv yog tias cov kua siv lead ua kua molecule ntawm TN torsional nematic field effect tig qhov teeb meem ntawm 90 degrees, thaum STN supertorsional nematic teb cov nyhuv tig qhov teeb meem ntawm 180 ~ 270 degrees. Nws yuav tsum raug sau tseg ntawm no tias cov ntshiab TN LCD nws tus kheej tsuas muaj ob lub teeb thiab tsaus ntuj (lossis dub thiab dawb), thiab tsis muaj txoj hauv kev kom ua tiav cov xim hloov. Txawm li cas los xij, yog tias cov xim lim tau ntxiv rau cov tsoos monochrome STN LCD, thiab ib qho pixel ntawm monochrome zaub matrix tau muab faib ua peb lub pixels, thiab peb lub ntsiab xim ntawm liab, ntsuab thiab xiav yog pom los ntawm colorfilter feem, thiab tom qab ntawd. qhov piv ntawm peb thawj xim yog kho. Koj tuaj yeem tso saib cov xim hauv hom xim puv. Tsis tas li ntawd, TN typeLCD zaub yog tias qhov screen loj dua, nws qhov kev sib piv ntawm qhov screen yuav tshwm sim tsis zoo, tab sis los ntawm STN txhim kho thev naus laus zis, nws tuaj yeem ua rau qhov tsis sib xws.

Xim zaub rau cov khoom siv mobile

Nyob rau saum npoo, STNLCD tsuas yog nce lub distortion Lub kaum sab xis ntawm cov kua siv lead ua kua molecules, tab sis qhov tseeb, nws nyob deb ntawm yog li ntawd, vim tias qhov ntau dua distortion Angle ua rau lwm tus yam ntxwv ntawm cov kua siv lead ua kua tshwm sim, uas yog birefringence kuv tau hais ua ntej. Lub teeb sab nraud uas ua rau lub phaj sab sauv dhau los ua ib lub teeb ntawm cov kab hluav taws xob polarized, tab sis lub teeb linearly polarized tsis tsuas yog cuam tshuam nws cov kev taw qhia raws li nws dhau los ntawm cov kua siv lead ua kua molecular txheej. Hloov chaw, nws faib ua ob kab -- lub teeb zoo tib yam thiab lub teeb txawv txawv -- uas cuam tshuam rau ib leeg ntawm lawv txoj kev tawm. Yog li, STNLCD ib txwm nthuav tawm qee yam xim tom qab (xws li ntsuab thiab xiav) thaum nws tsis muaj zog. Yog li, peb tuaj yeem pom tias cov ntsiab lus pom ntawm STNLCD yog qhov txawv ntawm TNLCD. Nws siv lub birefringence ntawm cov kua siv lead ua kua. Cov neeg txhawm rau txhawm rau tshem tawm STNLCD tom qab xim kom xav txog ntau txoj hauv kev, qhov yooj yim tshaj plaws yog siv ib qho zoo ib yam, tab sis cov kev taw qhia ntawm ob lub STNLCD lub thawv ua ke, kom qhov cuam tshuam ntawm ob kab teeb ntawm lub teeb thiab them nyiaj ib leeg. rov qab, thiaj li ua tiav cov duab dub thiab dawb, qhov no yog DSTN (DoubleSTN), tab sis tus nqi ntawm DSTN yog siab, Lub tswv yim yog siv txheej txheej ntawm iodine molecules los simulate cov kua siv lead ua kua cell, kom nyias nyias (theem theem sib txawv phaj) es tsis txhob siv cov kua siv lead ua kua, kom ua tiav cov duab dub thiab dawb, hu ua FSTN (FilmSTN). Txog tam sim no, kuv tuaj yeem hais tias txhua lub xov tooj dub thiab dawb yog FSTNS. STNLCD yog tus cwj pwm los ntawm qhov pom dav dav thiab muaj peev xwm loj. Nws qhov tsis zoo yog qeeb teb nrawm, vim tias qhov sib piv ntawm STN yog qis dua li ntawm TN vim muaj qhov muaj nyob ntawm multiplex tsav.

Cov xim ntawm STNLCD yog qhov peb hu ua CSTN (ColorSTN). Nws yog ib qho FSTN npo nrog cov yeeb yaj kiab xim. Siv RGB peb pixels los tsim ib lub pixel zaub. Lub hauv paus ntsiab lus ntawm CSTN yog tib yam li ntawm STN, yog li nws kuj tau txais txhua qhov zoo thiab qhov tsis zoo ntawm STNLCD. Cov lus teb qeeb yog nws qhov kev raug mob tuag taus. UFBLCD, uas yog siv nyob rau hauv qee lub xov tooj Samsung tam sim no, tseem yog CSTN, tab sis nrog kev nce me ntsis hauv qhov puv npo xa tawm thiab tom qab ntawd cuam tshuam rau 65K xim, nws tseem yog ib txwm CSTN, UFB, uas tsuas yog Samsung lub tswv yim. Ntau lub xov tooj xim tam sim no nyob rau hauv kev ua lag luam yog CSTNS, tsuas yog ob peb lub high-end xim screensTETLCD yog rau cov xov tooj ntawm tes. Zoo li G88N8 thiab T108.
