Isikrini se-LCD

I-Liquid Crystal Display (LCD) iyithuluzi lokubonisa elisebenzisa ubuchwepheshe bokudlulisa ukulawulwa kwe-liquid crystal ukuze kufezwe ukuboniswa kombala. Inezinzuzo zobukhulu obuncane, isisindo esincane, ukonga amandla, imisebe ephansi, kanye nokuphatheka kalula, futhi isetshenziswa kabanzi kuma-TV, ama-monitor, ama-laptop, amaphilisi, ama-smartphone nakwezinye izinkambu.Manje abaningiizinkampani ukwenza kahle emkhakheni we-TV.

I-LCD yaqala ngawo-1960. Ngo-1972, i-S.Kobayashi eJapane yaqala ukwenza iphutha - elingenasiciIsikrini se-LCD, kwabe sekuthi iSharp ne-Epson eJapan bayithuthukisa. Ngasekupheleni kweminyaka yama-1980, iJapan yazi kahle ubuchwepheshe bokukhiqiza be-STN – LCD kanye ne-TFT – LCD, kanti ama-TV e-crystal acwebezelayo aqala ukuthuthuka ngokushesha. Kamuva, iNingizimu Korea kanye neTaiwan, iShayina nazo zangena kulo mkhakha. Cishe ngo-2005, izwekazi laseShayina lalandela. Ngo-2021, umthamo wokukhiqiza wezikrini ze-LCD zaseShayina wadlula u-60% womthamo wokuthunyelwa komhlaba wonke, okwenza iShayina yaba ngeyokuqala emhlabeni.

Ama-LCD abonisa izithombe ngokusebenzisa izici zamakristalu aketshezi. Asebenzisa isisombululo sekristalu ewuketshezi phakathi kwezinto ezimbili ezihlukanisayo. Lapho ugesi udlula oketshezini, amakristalu ahlelwa kabusha ukuze kufezwe izithombe. Ngokusho kokusetshenziswa nokuqukethwe kokubonisa, ama-LCD angahlukaniswa ngezigaba - uhlobo, ichashazi - uhlamvu lwe-matrix - uhlobo kanye nechashazi - uhlobo lwe-matrix. Ngokwesakhiwo somzimba, ahlukaniswe nge-TN, STN, DSTN kanye ne-TFT. Phakathi kwawo, i-TFT - i-LCD iyithuluzi lokubonisa eliyinhloko.
