Emhlabeni wanamuhla owenziwe idijithali lapho ubuchwepheshe bugcwele kuzo zonke izici zokuphila, ubuchwepheshe be-LCD (Liquid Crystal Display) buthatha cishe ingxenye yemakethe eboniswayo, kusukela kuma-smartphone esiwasebenzisela amavidiyo amafushane, kuya kumakhompyutha omsebenzi, namathelevishini okuzijabulisa kwasekhaya. Ngaphandle kokuvela kobuchwepheshe obusha bokubonisa, i-LCD isalokhu iyingxenye ebalulekile yokuphila kwethu kwansuku zonke ngenxa yokuvuthwa kwayo, ukwethembeka, kanye nokusebenza kahle kwezindleko. Lesi sihloko sizochaza izici ezintathu ezibalulekile zobuchwepheshe be-LCD, siveze izimfihlo ezibangela ukuthandwa kwayo okuhlala njalo.
Isimiso Esisebenzayo kanye Nesakhiwo Esiyinhloko - "Izitho Ezibalulekile" ze-LCD
I-LCD imele “I-Liquid Crystal Display,” futhi ingqikithi yayo iyinto ekhethekile ebizwa ngokuthi “i-liquid crystal,” ekhona esimweni esiphakathi koketshezi nokuqinile. Kusukela ngo-1888, ososayensi bathola ukuthi ama-molecule ekristalu ewuketshezi ayekwazi ukuphinde ahleleke ngaphansi kwenkundla kagesi, asebenze “njengokushintsha kokukhanya” okungabaleki ukuze alawule ukudlula kokukhanya.
Ukuze kuzuzwe ukwakheka kwesithombe sokugcina, isikrini se-LCD sidinga izendlalelo ezinhlanu ezibalulekile ezisebenza ngokuxhumanisa okunembayo:
I-Backlight Layer: Ihlinzeka ngomthombo wokukhanya. Ama-LCD anamuhla ajwayele ukusebenzisa amalambu angemuva e-LED akhanya futhi awonga amandla.
I-Polarizer: Isebenza “njengomlindisango wokukhanya,” elawula isiqondiso sokudlidliza kokukhanya.
I-Electrode Glass Substrate: Ilawula i-engeli yokuzungezisa yama-molecule ekristalu ewuketshezi kuphikseli ngayinye ngokusebenzisa i-voltage.
I-Liquid Crystal Layer: Isendlalelo sokulawula esiyinhloko, esisebenza “njengezimpumputhe zaseVenetian,” silungisa inani lokukhanya elidlula ngokuzungeza kwamangqamuzana.
Isihlungi Sombala: Sihlanganisa imibala emithathu eyinhloko (RGB) ukuze kukhiqizwe imibala ecebile esiyibonayo.
Ukusebenza ngokubambisana kwalezi zingqimba ezinhlanu kwakha isisekelo sokuthwebula kwe-LCD kanye nesisekelo sokuthuthukisa okuqhubekayo kwekhwalithi yesithombe.
Izinhlobo Zobuchwepheshe Nokuthuthukiswa Kwekhwalithi Yesithombe- I-LCD Ecosystem Meeting Nezidingo Ezihlukahlukene
Ukuze uvumelane nezimo ezihlukene zohlelo lokusebenza, ubuchwepheshe be-LCD buguquke baba izinhlobo ezintathu ezijwayelekile:
Isikrini se-TN: Saziwa ngesikhathi saso sokuphendula esisheshayo kanye nezindleko eziphansi, iyisinqumo esivamile samadivayisi emidlalo, nakuba sinama-engeli amancane okubuka nokusebenza kombala okubuthakathaka.
Isikrini se-IPS: Sinikeza ukunemba kombala okuhle kakhulu nama-engeli okubuka abanzi, okuyenza ibe yinketho ekhethwayo yama-smartphone namamonitha asezingeni eliphezulu.
Isikrini se-VA: Sinezilinganiso eziphakeme zokugqama kanye namazinga amnyama ajulile, okusenza sithandeke kakhulu kumathelevishini namadivayisi we-multimedia.
Ukwengeza, ngokuqhubeka nokuthuthukisa ukulungiswa (kusuka ku-1080P kuya ku-8K), izinga lokuvuselela (kusuka ku-60Hz ukuya ku-240Hz nangale kwalokho), kanye nokuhlanganisa ubuchwepheshe be-HDR (High Dynamic Range) kanye namazinga ombala obanzi we-gamut, ikhwalithi yesithombe se-LCD iye yacwengwa kancane kancane, ihlinzeka ngolwazi olubushelelezi olufana nokuphila lokudalwa kwevidiyo okuphrofeshinali.
Ukuphila Okungapheli Kobuchwepheshe Abavuthiwe
Ibhekene nezinselele ezivela kubuchwepheshe obusha obufana ne-OLED ne-Mini-LED, i-LCD ayikahlehli. Ngenxa yenqubo yayo yokukhiqiza evuthiwe, izinzuzo zezindleko ezinganyakaziki, kanye nokusebenziseka kalula ezinhlelweni ezinosayizi omkhulu, i-LCD isaqhubeka nokubusa izimakethe ezivamile njengamathelevishini namamonitha. Ngokuzayo, ubuchwepheshe be-LCD buzogcina ukuncintisana kwabo okuqinile endaweni yokubonisa ngokuthuthukisa okuqhubekayo kanye nokusungula izinto ezintsha, ukuqhubeka nokuhlinzeka ngezixazululo ezithembekile zokubonisa kubasebenzisi bomhlaba.
