Ibisobanuro bigufi:

LCD (ngufi ya Liquid Crystal Display) yerekana ibintu bya kirisiti.

Imiterere ya LCD nugushira selile ya kirisiti hagati yikirahure kibangikanye.Ikirahuri cyo hepfo yububiko gifite ibikoresho bya TFT (tristoriste yoroheje), naho ikirahuri cyo hejuru kirimo ibikoresho byo kuyungurura.Ikimenyetso na voltage kuri TFT byahinduwe kugirango bigenzure molekile ya kirisiti.Kuzenguruka icyerekezo, kugirango ugenzure niba urumuri rwa polarize ya buri pigiseli yoherejwe cyangwa ntugere ku ntego yo kwerekana.

LCD yasimbuye CRT nkibisanzwe, kandi igiciro cyaragabanutse cyane, kandi kimaze kumenyekana rwose.

Ukurikije urumuri rutandukanye, LCD irashobora kugabanywamo ubwoko bubiri: CCFL na LED.

Kutumva nabi:

Abakoresha benshi bizera ko ibintu bisukuye bishobora kugabanywa LED na LCDs.Ku rugero runaka, iyi myumvire iyobowe niyamamaza.

LED yerekana kumasoko ntabwo yerekana LED nyayo.Kugirango bisobanutse neza, ni LED-isubira inyuma y'amazi ya kirisiti yerekana.Ikibaho cya kirisiti iracyari LCD gakondo.Mu buryo bumwe, ibi ni uburiganya.kamere!Samsung yo muri Koreya yepfo yigeze guhamwa n’ishyirahamwe ryamamaza abongereza ko yarenze ku mategeko yo kwamamaza iki gihugu kubera ko televiziyo ya “LEDTV” LCD yakekwagaho kuyobya abakiriya.Kubintu byamazi ya kirisiti yerekana, urufunguzo rwingenzi nuburyo bwa LCD nubwoko bwurumuri, mugihe LCD paneli yerekana kumasoko muri rusange ikoresha paneli ya TFT, nimwe.Itandukaniro riri hagati ya LED na LCDs nuko ubwoko bwurumuri rwinyuma butandukanye: LED Itara ryinyuma hamwe na CCFL itara (ni ukuvuga amatara ya fluorescent) ni diode n'amatara akonje ya cathode.

LCD ni impfunyapfunyo ya Liquid Crystal Display, bisobanura "kwerekana kristu yerekana", ni ukuvuga kwerekana ibintu bya kirisiti.LED bivuga ubwoko bwamazi ya kirisiti yerekana (LCD), ni ukuvuga, ibintu byerekana ibintu bisukuye (LCD) hamwe na LED (urumuri rusohora diode) nkisoko yinyuma.Birashobora kugaragara ko LCD irimo LED.Mugenzi wa LED mubyukuri ni CCFL.

CCFL

Yerekeza kumazi yerekana ibintu (LCD) hamwe na CCFL (itara rya cathode fluorescent itara) nkisoko yinyuma.

Ibyiza bya CCFL nibikorwa byiza byamabara, ariko ibibi ni ugukoresha ingufu nyinshi.

TFT-LCD

LED

Yerekeza kumazi yerekana ibintu (LCD) akoresha LED (urumuri rusohora urumuri) nkisoko yinyuma, kandi mubisanzwe yerekeza kuri WLEDs (urumuri rwera LED).

Ibyiza bya LED nubunini buke no gukoresha ingufu nke.Kubwibyo, gukoresha LED nkisoko yinyuma irashobora kugera kumurongo mwinshi mugihe uzirikana urumuri nubunini.Ingaruka nyamukuru ni uko imikorere yamabara ari mibi kurusha CCFL, kuburyo ibishushanyo mbonera byumwuga LCDs bigikoresha CCFL gakondo nkisoko yinyuma.

Igiciro gito

Muri rusange, kugabanya ibiciro byabaye itegeko ryingenzi kugirango ibigo bibeho.Mu mateka yiterambere rya TFT-LCD, ntago bigoye kubona ko kongera ubunini bwibirahure, kugabanya umubare wa masike, kongera umusaruro wa sitasiyo fatizo n'umusaruro wibicuruzwa, no kugura ibikoresho bibisi hafi ni imbaraga zihoraho za TFT- Abakora LCD..

Ibirahuri by'ibirahure ni ibikoresho by'ibanze byo gukora TFT-LCD, kandi igiciro cyacyo kigera kuri 15% kugeza 18% by'igiciro cyose cya TFT-LCD.Yateye imbere kuva kumurongo wambere (300mm × 400mm) kugeza kumurongo wa cumi wubu (2,850mm × 3,050).mm), byanyuze gusa mugihe gito cyimyaka makumyabiri.Ariko, kubera ibisabwa cyane cyane kubijyanye nimiterere yimiti, imikorere nuburyo bwo gutunganya ibintu bya TFT-LCD ibirahuri, ibirahuri bya TFT-LCD byogukora ibirahuri hamwe nisoko bimaze igihe kinini bikoreshwa na Corning muri Amerika, Asahi Glass na Ikirahuri cyamashanyarazi, nibindi Monopolisation namasosiyete make.Mu rwego rwo guteza imbere iterambere ry’isoko, umugabane wigihugu cyanjye nawo watangiye kugira uruhare rugaragara muri R&D no gutunganya ibirahuri bya TFT-LCD mu 2007. Kugeza ubu, imirongo myinshi y’ibirahure bya TFT-LCD yo mu gisekuru cya gatanu kandi hejuru yubatswe mu Bushinwa.Hateganijwe gutangiza ibice bibiri-8.5-by-ibisekuru-by-amazi-ya-kirisiti ya substrate yumusaruro mugice cya kabiri cya 2011.

Ibi biratanga ingwate yingenzi yo gutangiza ibikoresho fatizo bigezweho kubakora inganda za TFT-LCD mugihugu cyanjye no kugabanuka kwibiciro byinganda.

Igice kinini cyibikorwa bya tekinoroji ya TFT nuburyo bwo gufotora, ntabwo ari igice cyingenzi cyo kumenya ubuziranenge bwibicuruzwa, ahubwo ni igice cyingenzi kigira ingaruka kubiciro byibicuruzwa.Mubikorwa bya Photolithography, hitabwa cyane kuri mask.Ubwiza bwayo bugena ubuziranenge bwa TFT-LCD ku rugero runini, kandi kugabanya imikoreshereze yayo birashobora kugabanya neza ishoramari ryibikoresho no kugabanya umusaruro.Hamwe no guhindura imiterere ya TFT no kunoza imikorere yumusaruro, umubare wa masike yakoreshejwe mubikorwa byo gukora uragabanuka.Birashobora kugaragara ko uburyo bwo gukora TFT bwahindutse kuva muburyo bwa 8-mask cyangwa 7-mask ya lithographie kugeza ubu bikoreshwa cyane muri 5-mask cyangwa 4-mask ya lithographie, bigabanya cyane ukwezi kwa TFT-LCD no kugiciro cyumusaruro. .
