I-Crystal ewuketshezi isebenza kanjani

Ukuboniswa kwe-Liquid Crystal (LCDS) sekuyingxenye ebalulekile yezimpilo zethu zansuku zonke, kusuka kuma-Smartphones nakumathelevishini kubaqaphi bekhompyutha kanye nezimpawu zedijithali. Lokhu kuboniswa kunikeza izithombe eziphezulu ngezixazululo ezinemibala esebenzayo nama-engeli abukwayo amahle kakhulu. Kepha wake wazibuza ukuthi ama-molecule we-LCD asebenza kanjani ukudala okubonakalayo okumangalisa kangaka?

Enhliziyweni ye-LCD yi-liquid crystal molecule, ehlukile emandleni abo okuvumelanisa ngokwabo indlela ethile lapho ibhekwe yinsimu kagesi. Lawa ma-molekyuli enziwa izakhiwo ezinde, ezifana nenduku enezinto zombili eziwuketshezi nezesiko. Esimweni sabo semvelo, ama-molekyuli e-liquid Crystal athambekele ngokungahleliwe, okuholela ekubukekeni okumnyama lapho ukukhanya kudlula kubo.

Ukuqonda ukuthi ama-molecule asebenza kanjani we-LCD, ake sihlolisise ukwakheka okuyisisekelo kwephaneli ye-LCD. Siqukethe amapuleti amabili engilazi anesendlalelo esincanyana se-liquid crywiched efakwe phakathi kwabo. Ingaphakathi leplate yengilazi ngayinye ihlanganiswe ne-electrode esobala, evumela ukuthi i-Electric Field isetshenziswe ngaphesheya kwe-Liquid Crystal ungqimba.

I-liquid crystal molecule ku-LCD ngokuvamile ye-LCD: Isontekile nematic nematic nematic angvment (VA). Ku-TN LCD, ama-molecule ahambisana ne-angle ethile, imvamisa ama-degree angama-90, phakathi kwamapuleti ama-glass amabili lapho kungekho nkambu kagesi esetshenziswayo. Lokhu kuhlela okusontekile kuvumela ukukhanya ukuthi kudlule ungqimba lwe-Crystal uketshezi futhi ufinyelele isibukeli. ( Bona ividiyo lapha )

Lapho insimu kagesi isetshenziswa ku-TN LCD, ama-molecule e-crystal awuketshezi aqala ukungalwanga, azivumelanisa ngokufana nensimu kagesi. Lo mkhakha ushintsha ubumbano lokukhanya okudlula nge-liquid crystal ungqimba, ukulivimba ngempumelelo ekufinyeleleni isibukeli. Ngokulawula insimu kagesi, inani lokukhanya okudlula nge-LCD lingaba yilungelo lokulawulwa ngokunembile, okuphumela emazingeni ahlukene okukhanya.

Ngakolunye uhlangothi, uVa LCD wenza ngendlela ehlukile. E-VA LCD, ama-molecule e-liquid crystal aqondaniswe ngokuqondile, ahlala emapuleti engilazi. Lapho insimu kagesi isetshenziswa, ama-molecule attamba, avumela ukukhanya ukuthi kudlule ungqimba lwe-crystal ungqimba. Ifana ne-TN LCDS, izinga lokutsheka lingalawulwa ngokulungisa insimu kagesi, ngaleyo ndlela kulawule ukukhanya.

Ukuthuthukisa ukuthuthukisa ukusebenza kwama-LCD, izingxenye ezingeziwe ezinjengezihlungi zemibala nezinhlelo zokukhanyisa zifakiwe. Izihlungi zemibala zisetshenziselwa ukudala i-gamut yombala oyifunayo ngokukhetha ukukhanya okukhanyayo okudlula ungqimba lwe-crystal uketshezi. Izinhlelo zokukhanyisa, ngokuvamile zakhiwa ngama-LED, zinikeza ukukhanyisa okudingekayo kwephaneli ye-LCD.

Ngamafuphi, ama-molecule e-LCD asebenza ngokukhohlisa ukuhambisana kwezinhlaka zekristalu eziwuketshezi ngokusebenzisa inkambu kagesi. Lokhu kulawulwa okulawulwayo kuvumela i-LCD ukulawula ukudlula kokukhanya, okuholela ekubonisweni kwezithombe namavidiyo. Amandla wokulawula ngokunembile ukuqondiswa kwama-molekyuli e-Crystal Molekyuli akwenzele ubuchwepheshe obudumile kakhulu bokubonisa, enikeza okubonakalayo okuseqophelweni eliphezulu kumadivayisi ahlukahlukene.
