Izibani ezikhanyisa izibukeli ze- LCD zithinta ngokuqondile ikhwalithi yezithombe ezivela kuso. Uma kwenzeka ukwehluleka kwabo, lokhu kubhekene nemiphumela elandelayo:
- ukunyamalala kwesithombe esithombeni;
- vula isilonda okwesikhashana, cishe umzuzwana owodwa, bese uvala;
- ukuchofoza ngezikhathi kwesikrini nokukhanya okungazinzile;
- Shintsha isizinda sesiboniso noma ukubukeka kwamachashazi amnyama kuso;
- ikakhulukazi ezithombeni ze-shades obomvu.
Ngakho-ke, ukutholakala kwezibani ze-backlight eziphezulu kudlala indima ebalulekile ekuqinisekiseni ukusebenza kwayo okujwayelekile.
I-Fluorescent backlight i-LCD monitor
Ukuze kube nokusebenza okuqinile kwesimangalo se-LCD, umthombo wokukhanya ubaluleke kakhulu. I-flux yayo ekhanyayo yenza isithombe esikrinini. Ukuze udale ukukhanya okukhanyayo, ne-backlight ye-backlight ye-backlight nge-CFCL ebandayo. Zitholakala ezingxenyeni eziphezulu nezansi zomqapha. Inhloso yabo ukukhanyisa yonke indawo ye-matrix ye-LCD ne-matte diffusing glass.
Ungabuyisela kanjani ukubukeka kwesikrini?
Uma kwenzeka ukuthi i-backlight yomqapha we-CCFL ingalungile, kungenzeka ukuthi ukuxhumana nesikhungo sevisi akunikezi umphumela oyifunayo. Ngemva kwesikhashana, inkinga ibuyela futhi isibani sishiya ukusebenza. Kulesi simo, umbuzo uvela: kanjani ukufaka esikhundleni sesitoreji se-backlight isibani?
Okukhethwa kukho konke ukusebenzisa i-backlight LED esikhundleni sokubuyiselwa kwesikrini. Lokhu kuzokusiza ukuthuthukisa nokuthuthukisa ukubonisa kwakho.
Ngakho-ke, ukuze ukwazi ukuthola isithombe esiphezulu ngenkathi umlingo we-LCD usebenza, kuyadingeka ukuthi ukusebenza kwabo okungaphazanyiswa kuhlinzekwa ngezibani ze-backlight fluorescent. Uma kwenzeka ukwehluleka kwabo, ukukhanya kwe-LED kuzoxazulula inkinga.
