Kodi LCD Viewing Modes & Polarizers ndi chiyani?

Mawonekedwe a LCD & Polarizers

Nambala iliyonse ya LINFLOR Display Devices imafuna kuti mawonekedwe a Liquid Crystal Display Viewing ndi Polarizer afotokozedwe.Gawo lotsatira la Viewing Modes ndi Polarizers lifotokoza momwe Liquid Crystal Display yoyambira idzawonekera ndi Operating Mode yosankhidwa.

Mawonekedwe a LCD

Mtundu wa chithunzi chomwe chiwonetserochi chidzapanga ndi nkhani yodzikongoletsa yomwe dipatimenti ya engineering ndi malonda imakonza.Ili ndiye chisankho chophweka chifukwa pali zisankho ziwiri zokha, ndipo tikambirana chilichonse ndi zomwe zikutanthauza:

Chithunzi Chabwino

Chithunzi chowoneka bwino pachiwonetsero cha LCD ndi pamene pixel "yozimitsa" imakhala yowonekera, pomwe pixel mu "ON" imakhala yowoneka bwino.Pafupifupi mawonedwe onse chithunzicho ndi chaching'ono kusiyana ndi chakumbuyo, kotero kachitidwe kameneka kamakonda kugwiritsidwa ntchito komwe kuwala kozungulira kumakhala kokwera kwambiri ndipo kumathandizira kusiyanitsa kwa chiwonetserocho, makamaka chowonetsera pogwiritsa ntchito Reflective polarizer yakumbuyo.Nawa mitundu ingapo yophatikizira Njira Yogwirira Ntchito & Kuwonera ndi zithunzi zomwe zatuluka (pongoganiza kuti palibe kuyatsa komwe kungapangitse chakumbuyo):
TN:Zilembo zakuda pamtundu wa Imvi
STN-Green:Zilembo zakuda za Violet / zakuda pamtundu Wobiriwira.
STN-Silver:Zilembo za Blue Blue / Zakuda patsamba la Silver
FSTN:Zilembo zakuda pa White / Gray maziko

Chithunzi Cholakwika

Chithunzi choyipa pachiwonetsero cha LCD ndi pomwe pixel ili "WOZIMA" imakhala yosawoneka bwino, pomwe pixel mu "ON" imawonekera.Popeza malo azithunzi nthawi zambiri amakhala aang'ono kuposa chakumbuyo, gawo lachiwonetsero lomwe lingawonetse kuwala ndikupereka tanthauzo la zilembo munjira iyi limachepetsedwa.Chifukwa chake, mawonekedwewa amangogwiritsidwa ntchito ngati pali chowunikira chakumbuyo ndipo kuyatsa kozungulira kumakhala kwapakati mpaka mdima.Pogwiritsa ntchito chowunikira chakumbuyo, magawo owonekera awonetsero "adzawala" chifukwa chowunikiranso chidzawoneka kokha ma pixel akayatsidwa.Kuwala kozungulira kwambiri kumatha kutsuka nyali yakumbuyo.Nawa mitundu ingapo yophatikizira Njira Yogwirira Ntchito & Kuwonera ndi zithunzi zomwe zatuluka (kutengera kuwala kwambuyo ndi mitundu yomwe yatchulidwa):
TN:Zilembo zonyezimira za Green-Yellow pazithunzi zotuwa zopepuka (Kumbuyo kwa Green-Yellow Backlight)
STN ("Blue-Negative"):Zilembo zonyezimira za Green-Yellow pamtundu wa Buluu wopepuka (Kumbuyo kwa Green-Yellow Backlight)
FSTN:Zilembo zonyezimira zoyera kumbuyo kwakuda (Kumbuyo Koyera)

LCD Polarizers

LCD iliyonse ili ndi 2 polarizers, kutsogolo ndi kumbuyo polarizers, kuikidwa moyenerera kutsogolo kwa chionetserocho kuonera pamwamba ndi kumbuyo kwa chionetserocho kudziwa mmene kuwala kulowetsera pachiwonetsero.Polarizer yakutsogolo nthawi zonse imakhala Transmissive komanso yosasankhidwa ndi wogwiritsa ntchito, komabe polarizer yakumbuyo ili ndi zosankha 3 ndi magiredi awiri pachisankho chilichonse.Kusankhidwa kwa polarizer kumbuyo kuli motere:

Polarizer yowunikira

Zowonetsera zowunikira zimakhala ndi polarizer yakumbuyo yowoneka bwino yomwe imakhala ndi chowunikira chowoneka bwino, monga aluminiyamu yopukutidwa.Chosanjikiza ichi chikuwonetsa kuwala kozungulira komwe kwalowa kutsogolo kwa chiwonetserochi kudzera mu cell ya LCD.Zowonetsera zimafunikira kuwala kozungulira kuti muwonekere.Amawonetsa kuwala kwakukulu, kusiyanitsa kwakukulu, ndi ma angles owoneka bwino.Ndizoyenera kwambiri kugwiritsidwa ntchito pazida zogwiritsira ntchito batri komwe kuwala kokwanira kumakhalapo nthawi zonse.Ma LCD owonetsera sangayatsidwenso, komabe amatha kuyatsa patsogolo pamapulogalamu ena.

Transmissive Polarizer

Zowonetsera zowonekera zimakhala ndi polarizer yomveka bwino kutsogolo ndi kumbuyo.Chowonetseracho chimadalira kuwala komwe kumabwera kuchokera kumbuyo kwa chowonetsera kupita kwa wowonera kuti awonedwe.Zambiri, koma sizithunzi zonse zomwe zimakhala ndi zithunzi zolakwika, ndipo nthawi zina timawonjezera zosefera zamitundu kumadera osiyanasiyana awonetsero kuti tiwunikire zolengeza zosiyanasiyana.Chitsanzo china cha chiwonetsero cha polarizer chodutsa chingakhale zenera lowonekera pomwe mutha kuwona magawo omwe ali pamwamba pa masomphenya anu kudzera pazenera lowonetsera (izi zimatengera kuwala kokwanira komwe kulipo mbali zonse za zenera).

Transflective Polarizer

Zowonetsera zosinthika zimakhala ndi polarizer yakumbuyo yomwe imakhala ndi zinthu zowoneka bwino zomwe zimawonetsa gawo la kuwala kozungulira, komanso zimatumiza kuwunikiranso.Monga momwe dzinalo likusonyezera, ndi kusagwirizana pakati pa njira yowonetsera ndi yowonetsera.Imagwiritsidwa ntchito powunikira, siwowala komanso ili ndi kusiyana kocheperako kuposa mtundu wonyezimira wa LCD, koma imatha kuyatsidwanso kuti igwiritsidwe ntchito pakuwala kochepa.Polarizer iyi ndiye chisankho chabwino kwambiri chowonetsera chomwe chingagwiritsidwe ntchito pazowunikira zonse ndi nyali yakumbuyo.
