TFT-LCD: description, manufa na aiki

A zamani iyali kayan yadu amfani da wani kashi kamar wani TFT-nuni. Ana amfani da daban-daban iri na'urorin: kwamfuta zaune a yanki, televisions, wayar hannu fuska, a camcorders da kyamarori, kazalika da yawa wasu na'urorin. Abin da irin fasaha, abin da suke amfanin? A cikin wannan labarin, za mu bincika abin da ya ƙunshi wani TFT-LCD, ta amfani ko rashin amfani.

Thin-film transistor (TFT) ya fassara zuwa harshen Turanci na nufin wani bakin ciki-film transistor. Wadannan abubuwa suna sanya daga bakin ciki fim kauri daga 0.1-0.01 micrometer. Ga irin transistors da kuma sarrafawa da TFT-matrix, duk da haka shi ne ake kira "aiki". M hada da ruwa crystal na'urorin. Active TFT-nuni, da bambanci ga LCD fasahar, yana da babban gudun, wani yafi hakan tsabta da bambanci na image da muhimmanci m Viewing kwana. A wadannan na'urori akwai wani allo flicker, daga abin da gaji idanu. A cikin aiki matrix pixel sa radiation haske juyi tare da wata qaddara launi, don haka TFT-nuni ne da yawa haske fiye da m matrix LCD. Duk wadannan amfanin ne saboda gaskiyar cewa da aka bayyana fasahar yana da mafi girma image Wartsakewa kudi. Wannan shi ne saboda cewa kowane batu na nuni ne sarrafawa ta mai raba bakin ciki fim transistor. Yawan irin wannan abubuwa a TFT-fasahar ne sau uku fi girma fiye da yawan pixels. Saboda haka, daya batu wasa uku canza launin Kwayoyin: ja, kore da kuma shudi (RGB tsarin). Alal misali, ka yi la'akari da matrix: nuni TFT (launi) tare da wani ƙuduri na 1280x1024 pixels, bi da bi, yawan transistors a cikin irin wannan na'urar za ta zama 3840h1024.

A farko ruwa crystal matrix bayyana a cikin shekara ta 1972. Tun daga nan, da fasahar ya ƙwarai samo asali da kuma canza. Duk da haka, duk ba zai yiwu ba ya kawar da shortcomings. Alal misali, saboda da manyan yawan pixels ne sau da yawa daga cikinsu za a iya samu "karye", da cewa shi ne ya karye. Irin wannan spoiled ma'ana ba za a iya gyara. Ya kamata a lura cewa a kan aiki matrix "karye" pixels ne kasa m fiye da m na'urorin ko nuni, dual scan. Bunkasuwar TFT-fasahar ya rage muhimmanci da kudin samar da irin wannan a yanki suna a yanzu "tsada m" ya zama sananne. An muhimmanci factor a tartsatsi aiki matrix a cikin masana'antu ya da sauƙi na amfani. Yau ba wanda yake mamakin taba garkuwa TFT-nuni, da kuma shekaru ashirin da suka wuce, shi ne wani yi. Rasprostanenie touchmonitors gabãta bayyanar model, iya aiki a cikin matsananci halin wurare. A sakamakon haka shi da wani TFT-nuni naúrar, hada wajen domin nuna gani bayanai, da kuma wani labari na'urar (keyboard). Yadda ya dace da irin wannan tsarin samar da wani serial dubawa kula. Wannan na'urar a hannu daya aka haɗa ta duba da kuma sauran - ga serial tashar jiragen ruwa (COM1 - COM4). Don sarrafa da kuma karanta sakonni daga haska, kazalika da danniya da "billa" da aka yi amfani da pic-rinjãya. Suna kuma iya samar da babban gudun da kuma daidaito a kayyade touch maki.

A ƙarshe, mun ce cewa TFT-fasahar matsayin nuni da na'urori masu auna sigina suna kewaye da mu a cikin rayuwar yau da kullum, suna amfani da kusan kowane iyali nema.
