M'dziko lamakono lamakono momwe luso laukadaulo limalowa m'mbali zonse za moyo, ukadaulo wa LCD (Liquid Crystal Display) umatenga pafupifupi theka la msika wowonetsedwa, kuyambira pa mafoni omwe timagwiritsa ntchito pamavidiyo afupiafupi, mpaka pamakompyuta pantchito, ndi makanema apakanema osangalatsa a kunyumba. Ngakhale ukadaulo watsopano wawonekera, LCD ikadali gawo lofunika kwambiri pa moyo wathu watsiku ndi tsiku chifukwa cha kukhwima, kudalirika, komanso kutsika mtengo. Nkhaniyi ifotokoza mbali zitatu zazikuluzikulu zaukadaulo wa LCD, kuwulula zinsinsi zomwe zimapangitsa kutchuka kwake kosatha.
Mfundo Yogwira Ntchito ndi Mapangidwe Apakati - "Zigawo Zofunikira" za LCD
LCD imayimira "Liquid Crystal Display," ndipo pachimake chake ndi chinthu chapadera chotchedwa "liquid crystal," chomwe chimakhala pakati pa madzi ndi olimba. Pofika m'chaka cha 1888, asayansi adapeza kuti mamolekyu amadzimadzi amatha kusinthika pansi pa malo amagetsi, kumachita ngati "ma switch ang'onoang'ono" kuti azitha kuyendetsa bwino kuwala.
Kuti mukwaniritse kupanga chithunzi chomaliza, chophimba cha LCD chimafunikira zigawo zisanu zazikuluzikulu zomwe zikugwira ntchito molumikizana bwino:
Backlight Layer: Amapereka gwero la kuwala. Ma LCD amakono amagwiritsa ntchito nyali zowala komanso zopatsa mphamvu zowonjezera za LED.
Polarizer: Imagwira ntchito ngati "mlonda wa pachipata cha kuwala," kuwongolera komwe kumayendera kuwala.
Electrode Glass Substrate: Imawongolera kozungulira kwa mamolekyu amadzimadzi amadzimadzi mu pixel iliyonse pogwiritsa ntchito voliyumu.
Liquid Crystal Layer: Chigawo chapakati chowongolera, chimagwira ntchito ngati "makhungu a Venetian," kusintha kuchuluka kwa kuwala komwe kumadutsa pozungulira mamolekyulu.
Zosefera Zamitundu: Zimaphatikiza mitundu itatu yayikulu (RGB) kuti ipange mitundu yolemera yomwe timawona.
Kugwiritsiridwa ntchito kwa zigawo zisanuzi kumapanga maziko a kujambula kwa LCD ndi maziko a kukhathamiritsa kwake kosalekeza kwa khalidwe lazithunzi.
Mitundu Yaukadaulo ndi Kukhathamiritsa Kwa Ubwino Wazithunzi- Kukumana ndi Zosowa Zosiyanasiyana za LCD Ecosystem
Kuti zigwirizane ndi zochitika zosiyanasiyana zogwiritsira ntchito, ukadaulo wa LCD wasintha kukhala mitundu itatu yayikulu:
TN Screen: Yodziwika chifukwa cha nthawi yake yoyankha mwachangu komanso mtengo wotsika, ndi chisankho chofala pazida zamasewera, ngakhale ili ndi ngodya zocheperako komanso mawonekedwe ocheperako amitundu.
IPS Screen: Imapereka kulondola kwamitundu yabwino komanso ma angles owoneka bwino, ndikupangitsa kuti ikhale chisankho chokondedwa cha mafoni a m'manja ndi zowunikira zapamwamba.
VA Screen: Imakhala ndi milingo yosiyana kwambiri komanso milingo yakuda yakuya, ndikupangitsa kuti ikhale yoyamikiridwa kwambiri ndi makanema apa TV ndi ma multimedia.
Kuphatikiza apo, pakuwongolera mosalekeza kusamvana (kuchokera ku 1080P mpaka 8K), kutsitsimula (kuchokera ku 60Hz mpaka 240Hz ndi kupitirira), ndikuphatikiza ukadaulo wa HDR (High Dynamic Range) ndi miyezo yamitundu yosiyanasiyana yamitundu, mawonekedwe azithunzi a LCD asinthidwa pang'onopang'ono, akupereka zowoneka bwino komanso zowoneka ngati zamoyo pakupanga masewera, makanema ojambula.
Ubwino Wosatha Waukadaulo Wokhwima
Poyang'anizana ndi zovuta zamakina atsopano monga OLED ndi Mini-LED, LCD sinabwerere. Chifukwa cha njira yake yopangira anthu okhwima kwambiri, mtengo wake wosasunthika, komanso kusavuta kugwiritsa ntchito zazikuluzikulu, LCD ikupitilizabe kulamulira misika yayikulu monga ma TV ndi oyang'anira. M'tsogolomu, teknoloji ya LCD idzapitirizabe kukhala ndi mpikisano wolimba m'munda wowonetsera pogwiritsa ntchito kukhathamiritsa kosalekeza ndi zatsopano, ndikupitiriza kupereka mayankho odalirika owonetsera ogwiritsa ntchito padziko lonse lapansi.
