Kodi chiwonetsero cha kristalo chamadzimadzi (LCD) ndi chiyani? Tanthauzo la zowonetsera za LCD ndi momwe zimasiyanirana ndi zowonetsera za LED

Mitu Yovumbulutsidwa Onetsani

Mwachidule kwa LCD, mawonekedwe amadzimadzi amadzimadzi ndi chipangizo choonda, chosalala chomwe chalowa m'malo mwa makina akale a CRT. Chophimba cha LCD chimapereka chithunzithunzi chabwinoko komanso chithandizo chazosankha zazikulu.

Kawirikawiri, LCD imatanthauza mtundu wa zowonetsera zomwe zimagwiritsa ntchito ukadaulo wa LCD, komanso zowonetsera zowoneka bwino monga zomwe zimapezeka m'makompyuta apakompyuta, zowerengera, makamera a digito, mawotchi a digito, ndi zida zina zofananira.

Palinso lamulo la FTP lomwe limagwiritsa ntchito zilembo "LCD". Ngati ndi zomwe mukuyang'ana, ndiye kuti mungathe Werengani zambiri za izo patsamba la Microsoft , koma ilibe chochita ndi makompyuta kapena zowonetsera TV.

Kodi zowonera za LCD zimagwira ntchito bwanji?

Monga chiwonetsero cha kristalo chikuwonetsa madzi Zowonetsera za LCD zimagwiritsa ntchito makhiristo amadzimadzi kuyatsa ndi kuzimitsa ma pixel kuti awonetse mtundu wina. Makristasi amadzimadzi ali ngati kusakaniza pakati pa cholimba ndi madzi, momwe mphamvu yamagetsi ingagwiritsidwe ntchito kusintha dziko lawo kuti achitepo kanthu.

Makhiristo amadzimadzi awa amatha kuganiziridwa ngati chotsekera pazenera. Chotsekera chikatsegulidwa, kuwala kumatha kulowa mchipindamo mosavuta. Ndi zowonetsera za LCD, pamene makhiristo akugwirizana mwapadera, samalola kuwala kudutsa.

Ndi kuseri kwa LCD komwe kumayang'anira kuwunikira pazenera. Kutsogolo kwa kuwalako pali chinsalu chopangidwa ndi ma pixel amitundu yofiira, yabuluu kapena yobiriwira. Makhiristo amadzimadzi ali ndi udindo woyatsa kapena kuzimitsa fyulutayo kuti azindikire mtundu winawake kapena kusunga pixel yakudayo.

Izi zikutanthauza kuti oyang'anira LCD amagwira ntchito poletsa kuwala komwe kumachokera kumbuyo kwa chinsalu m'malo mopanga kuwala komweko monga momwe oyang'anira CRT amachitira. Izi zimathandiza owunikira a LCD ndi ma TV kuti agwiritse ntchito mphamvu zochepa kuposa za CRT.

LCD vs LED: Pali kusiyana kotani?

LED imayimira Kuwala kotulutsa diode . Ngakhale ili ndi dzina losiyana ndi Show kristalo wamadzimadzi , kupatula kuti sichinthu chosiyana kotheratu, koma kwenikweni ndi cholungama Mtundu Mitundu yosiyanasiyana ya ma LCD.

Kusiyana kwakukulu pakati pa LCD ndi LED zowonetsera ndi momwe kuwala kwambuyo kumaperekedwa. Kuwala kwapambuyo kumasonyeza momwe mungatsegule kapena kuzimitsa chinsalu, chomwe chili chofunikira kuti mupereke chithunzi chabwino, makamaka pakati pa mbali zakuda ndi zakuda za chinsalu.

Chojambula chokhazikika cha LCD chimagwiritsa ntchito nyali yozizira ya cathode fluorescent (CCFL) powunikiranso kumbuyo, pomwe zowonetsera za LED zimagwiritsa ntchito ma photodiodes ang'onoang'ono (LED). Kusiyana kwake ndikuti CCFL yowunikiranso LCD zowonetsera sizingatseke nthawi zonse zonse Akuda, momwemo ngati mawonekedwe akuda-oyera mufilimu yakuda kwambiri sangawonekere konse, pamene ma LCD a LED-backlit amatha kusankha akuda kusiyana kwakukulu.

Ngati mukuvutika kumvetsa izi, ingoganizirani za filimu yamdima monga chitsanzo. M'malo mwake muli chipinda chakuda chakuda chomwe chili ndi chitseko chotsekedwa chomwe chimalowetsa kuwala kwina kupyola pansi. Chowonetsera cha LED-backlit LCD chingathe kuchikoka bwino kuposa zowonetsera CCFL zobwereranso chifukwa zoyambazo zimatha kusewera mtundu wa gawo lozungulira pakhomo, ndikulola kuti chinsalucho chikhale chakuda kwenikweni.

Osati chophimba chilichonse cha LED chomwe chimatha kuyimitsa chinsalu kwanuko, monga momwe ndawerengera. Nthawi zambiri amakhala ma TV amtundu wathunthu (kuyerekeza ndi owala m'mphepete) omwe amathandizira kuzimiririka kwanuko.

Zowonjezera pa LCD

Ndikofunika kusamala pamene Kuyeretsa zowonetsera LCD , akhale ma TV, mafoni am'manja, zowunikira makompyuta, ndi zina.

Mosiyana ndi oyang'anira CRT ndi ma TV, owunikira a LCD alibe mtengo wotsitsimutsa . Mungafunike kusintha Tsitsaninso zosintha  Yang'anirani pa chowunikira cha CRT ngati vuto lamaso liri vuto, koma sikofunikira pa zowunikira zatsopano za LCD.

Oyang'anira makompyuta ambiri a LCD amakhala ndi chingwe HDMI و DVI. Ena amathandizirabe Zingwe VGA , koma izi ndizochepa. Ngati kanema khadi ku kompyuta yanu kuthandizira akale VGA kugwirizana, kawiri fufuzani LCD wanu chikugwirizana izo. Mungafunike kugula adaputala ya VGA kupita ku HDMI kapena adaputala ya VGA kupita ku DVI kuti malekezero onse agwiritsidwe ntchito pa chipangizo chilichonse.

Ngati palibe chomwe chikuwoneka pakompyuta yanu, mutha kuchita zomwe zili patsamba lathu lazovuta Momwe mungayesere chophimba pakompyuta chomwe sichikugwira ntchito kuti mudziwe chifukwa chake.

Malangizo
  • Kodi LCD screen burn-in ndi chiyani?

    Ma CRTs, omwe amatsogolera ku zowonetsera zamadzimadzi, anali owopsa kwambiri kuyaka pa skrini , chomwe ndi chithunzi chofooka chosindikizidwa pakompyuta chomwe sichikhoza kuchotsedwa.

  • Kodi LCD conditioning ndi chiyani?

    LCD Adaptation imathetsa mavuto ang'onoang'ono omwe amapezeka pazithunzi za LCD, kuphatikiza zithunzi kapena zithunzi za mizimu. Njirayi imaphatikizapo kusefukira pazenera kapena chophimba ndi mitundu yosiyanasiyana (kapena yoyera kwathunthu). Dell akuphatikiza Chithunzi Adaptation muzowunikira zake za LCD.

  • Vuto lomwe lingakhalepo ndi chiyani ngati muwona mawanga ang'onoang'ono oyera, akuda kapena amtundu pa LCD yanu?

    Ngati muwona malo akuda omwe sasintha, mwina ndi pixel yakufa ndipo angafunike kukonza akatswiri kapena kusintha mawonekedwe. Ma pixel okhazikika amakhala ofiira, obiriwira, abuluu, kapena achikasu (ngakhale amatha kukhala akuda nthawi zina). Mayeso a pixel akufa amasiyanitsa ma pixel wokakamira ndi wakufa.
