Isikrini se-LCD

I-Liquid Crystal Display (LCD) iyithuluzi lokubonisa esebenzisa ubuchwepheshe bokudlulisa ikristalu eliwuketshezi ukuze kuzuzwe ukuboniswa kombala. Inezinzuzo zosayizi omncane, isisindo esilula, ukonga amandla, imisebe ephansi, nokuphatheka kalula, futhi isetshenziswa kakhulu kumasethi we-TV, iziqapha, amalaptop, amaphilisi, ama-smartphone kanye neminye imikhakha.Manje abaningiizinkampani zihamba phambili emkhakheni we-TV.

I-LCD yasungulwa ngawo-1960. Ngo-1972, uS.Kobayashi eJapane waqala ukwenza iphutha - mahhalaIsikrini se-LCD, kwase kuthi i-Sharp ne-Epson yaseJapane bayithuthukisa ngokwezimboni. Ngasekupheleni kwawo-1980, iJapane yazuza ubuchwepheshe bokukhiqiza be-STN - LCD ne-TFT - LCD, kanye nama-TV - crystal TV aqala ukuthuthuka ngokushesha. Kamuva, iSouth Korea neTaiwan, iChina nayo yangena kulo mkhakha. Cishe ngo-2005, izwe laseShayina lalandela. Ngo-2021, umthamo wokukhiqiza wezikrini ze-LCD zamaShayina wedlula u-60% wevolumu yokuthunyelwa komhlaba wonke, okwenza iChina yaba ngeyokuqala emhlabeni.

Ama-LCD abonisa izithombe ngokusebenzisa izici zamakristalu awuketshezi. Basebenzisa isixazululo sekristalu esiwuketshezi phakathi kwezinto ezimbili ezihlukanisayo. Lapho amandla kagesi edlula oketshezini, amakristalu ahlelwa kabusha ukuze kuzuzwe isithombe. Ngokusetshenziswa nokuqukethwe okuboniswayo, ama-LCD angahlukaniswa abe ingxenye - uhlobo, ichashazi - uhlamvu lwe-matrix - uhlobo kanye nechashazi - umfanekiso we-matrix - uhlobo. Ngokwesakhiwo somzimba, zihlukaniswe zibe yi-TN, STN, DSTN kanye ne-TFT. Phakathi kwazo, i-TFT - LCD iyithuluzi lokubonisa elijwayelekile.
