Chiwonetsero cha 128 × 64 Dot Matrix Lcd, Chiwonetsero cha Fstn Lcd, 128 × 64 STN Lcd Display,

1, TN LCD ndi chiyani?

TN LCD (Twisted Nematic Liquid Crystal Display) ndi mtundu waukadaulo wa LCD womwe umagwiritsidwa ntchito powonetsa pa digito, ma TV, zowunikira makompyuta, ndi zida zam'manja.Imadziwika ndi nthawi yake yoyankha mwachangu, kuwala kwambiri, komanso kutsika mtengo kopanga.TN LCDs imagwiritsa ntchito mamolekyu amadzimadzi amadzimadzi omwe amazungulira mopotoka pamene magetsi agwiritsidwa ntchito kwa iwo.Ukadaulo wamtundu uwu wa LCD umagwiritsidwa ntchito kwambiri chifukwa chakutha kwake, koma nthawi zambiri umapereka ma angles owonera pang'ono komanso kulondola kwamitundu poyerekeza ndi matekinoloje ena a LCD monga IPS (In-Plane Switching) ndi VA (Vertical Alignment).

2, STN LCD ndi chiyani?

STN LCD (Super-Twisted Nematic Liquid Crystal Display) ndi mtundu waukadaulo wa LCD womwe ndikupita patsogolo kwa TN LCD.Zimakhala bwino pamtundu ndi kusiyanitsa kwa TN LCD, komanso kupereka mphamvu zochepa.Ma LCD a STN amagwiritsa ntchito mawonekedwe opindika kwambiri a nematic omwe amalola kuwongolera bwino kwa mamolekyu amadzimadzi amadzimadzi, zomwe zimapangitsa kuti chithunzicho chikhale bwino.Kapangidwe ka nematic kokhotakhota kwambiri kumapangitsa kuti kristalo wamadzimadzi azilumikizana bwino, zomwe zimathandiza kukulitsa mawonedwe a chiwonetserochi ndikupereka milingo yayikulu yosiyana ndi kuchulukira kwamitundu.Ma LCD a STN amagwiritsidwa ntchito kwambiri pazida monga zowerengera, mawotchi a digito, ndi mafoni am'manja akale.Komabe, idathetsedwa kwambiri ndi matekinoloje apamwamba kwambiri a LCD monga TFT (Thin Film Transistor) ndi IPS (In-Plane Switching).

3, FSTN LCD ndi chiyani?

FSTN LCD (Film-compensated Super Twisted Nematic Liquid Crystal Display) ndi mtundu waukadaulo wa STN LCD.Imagwiritsa ntchito chiwongola dzanja cha filimu kuti chiwongolere mawonekedwe ake.Chiwongola dzanja cha filimu chimawonjezedwa ku STN LCD kuti muchepetse vuto la grey scale inversion lomwe nthawi zambiri limapezeka muzowonetsera zachikhalidwe za STN.Vuto la kutembenuka kwa imvi kumabweretsa kuchepa kwa kusiyanitsa ndi kuwoneka mukamawona mosiyanasiyana.
Ma FSTN LCD amapereka ma retiwolo owoneka bwino, ma angles owonera ambiri, komanso mawonekedwe abwinoko poyerekeza ndi ma STN LCD.Amatha kuwonetsa zithunzi zabwino ndi zoipa posintha voteji yomwe imagwiritsidwa ntchito ku maselo amadzimadzi a crystal.Ma FSTN LCD amagwiritsidwa ntchito kwambiri m'mapulogalamu omwe amafunikira kusiyanitsa kwakukulu komanso kowonera bwino, monga mawotchi anzeru, mapanelo owongolera mafakitale, ndi zida zamankhwala.

4, VA LCD ndi chiyani?

VA LCD imayimira Vertical Alignment Liquid Crystal Display.Ndi mtundu waukadaulo wa LCD womwe umagwiritsa ntchito mamolekyu amadzi amadzi osunthika kuti azitha kuyendetsa kuwala.
Mu VA LCD, mamolekyu amadzimadzi amadzimadzi amadzigwirizanitsa okha pakati pa magawo awiri agalasi pamene palibe magetsi.Mphamvu yamagetsi ikagwiritsidwa ntchito, mamolekyu amapindika kuti agwirizane mozungulira, kutsekereza kutuluka kwa kuwala.Kuyenda kokhotakhota kumeneku kumapangitsa VA LCDs kuwongolera kuchuluka kwa kuwala komwe kumadutsamo ndikupanga milingo yosiyanasiyana yowala kapena mdima.

Ubwino umodzi wofunikira waukadaulo wa VA LCD ndikuthekera kwake kukwanitsa kusiyanitsa kwakukulu.Mamolekyu amadzimadzi oyenda moyima komanso kuwongolera njira yowunikira kumapangitsa kuti pakhale zoyera zakuda ndi zoyera, zomwe zimapangitsa kuti pakhale mawonekedwe owoneka bwino komanso owoneka ngati moyo.VA LCDs imaperekanso ma angles owonera ambiri poyerekeza ndi ma LCD a TN (Twisted Nematic), ngakhale sangafanane ndi ma LCD a IPS (In-Plane Switching).

Chifukwa cha kusiyanasiyana kwawo kopambana, kutulutsa bwino kwamitundu, komanso kuwonera mokulirapo, ma VA ma LCD amagwiritsidwa ntchito kwambiri pama TV apamwamba komanso zowunikira zamakompyuta, komanso pazida zina zam'manja, zida zamasewera, ndi zowonera zamagalimoto.
