Isikrini se-LCD

I-Liquid Crystal Display (LCD) sisixhobo sokubonisa esisebenzisa iteknoloji yokudlulisa i-liquid crystal control ukuze kufezekiswe umboniso wombala. Inezibonelelo zobukhulu obuncinci, ubunzima obulula, ukonga amandla, i-radiation ephantsi, kunye nokuphatheka lula, kwaye isetyenziswa kakhulu kwiiTV, iimonitha, iilaptop, iitablet, ii-smartphones nakwezinye iindawo.Ngoku zininziiinkampani ukugqwesa kwicandelo leTV.

I-LCD yaqala ngeminyaka yoo-1960. Ngo-1972, i-S.Kobayashi eJapan yaqala ukwenza isiphene - esingenasiphako.Isikrini se-LCD, emva koko iSharp kunye ne-Epson eJapan zayenza yaba yimizi-mveliso. Ngasekupheleni kweminyaka yoo-1980, iJapan yazi kakuhle iiteknoloji zemveliso ze-STN – LCD kunye ne-TFT – LCD, kwaye iiTV zekristale ezingamanzi zaqala ukukhula ngokukhawuleza. Kamva, uMzantsi Korea kunye neTaiwan, iTshayina nazo zangena kweli shishini. Malunga nowama-2005, ilizwekazi laseTshayina lalandela. Ngowama-2021, umthamo wemveliso yezikrini zeLCD zaseTshayina wadlula i-60% yomthamo wokuthunyelwa kwehlabathi, nto leyo eyenza iTshayina yaba yeyokuqala ehlabathini.

Ii-LCD zibonisa imifanekiso ngokusebenzisa iimpawu zeekristale zolwelo. Zisebenzisa isisombululo sekristale yolwelo phakathi kwezinto ezimbini ezidibanisayo. Xa umbane udlula kulwelo, iikristale ziyahlengahlengiswa ukuze kufezekiswe umfanekiso. Ngokwendlela esetyenziswa ngayo kunye nomxholo wokubonisa, ii-LCD zinokwahlulwa zibe ziinxalenye – uhlobo, ichaphaza – uphawu lwe-matrix – uhlobo kunye nechaphaza – igrafu ye-matrix – uhlobo. Ngokwesakhiwo somzimba, zahlulwe zibe yi-TN, STN, DSTN kunye ne-TFT. Phakathi kwazo, i-TFT – LCD sisixhobo esiphambili sokubonisa.
