Kusankha kwamawonetsedwe amakampani sikotsika mtengo kwambiri kuposa, koma kusankha zosankha zanu malinga ndi zosowa zanu ndikupatsirani chidziwitso choyenera kwambiri. Otsatirawa akufotokoza momwe tingasankhire chiwonetsero choyenera kwambiri cha mafakitale fRom momwe moyo wa backlight, ozizira cathode fluorescence, mtundu, ndi zina zambiri.

　　 Yoyamba ndi kuwala kwa nthawi yozizira ya cathode fluorescence (CCF). Pakugwiritsa ntchito mafakitale, nthawi yayitali ya magetsi a CCF nthawi zambiri amakhala maola 50,000, kapena kuwala kumatsika mpaka theka poyerekeza ndi zatsopano. Muzinthu zambiri zogwiritsira ntchito, izo zimapitiriray imatenga maola 10,000 kuti kuwala kwa backlight kugwere mpaka theka la kuwala kwake koyamba. Chifukwa kugwiritsa ntchito kwa ogula sikutanthauza kuti chiwonetserochi chizigwirabe ntchito, nthawi zonse ma CCF owala maola 10,000 ndi okwanira, koma sizili choncho pakagwiridwe kantchito ndi zamankhwala. Poyerekeza ndi LCD, moyo wamtundu wa backlight ndiufupi kwambiri. Anthu akugwira ntchito molimbika kuti awonjezere moyo wantchito ya backlight, koma muntchito zambiri zamakampani, moyo wocheperako wa maola 5000 umawerengedwa kuti ndi moyo wanthawi zonse wa CCF.

　　Kachiwiri, paziwonetsero zamagalasi amadzimadzi, kuyerekezera kwamtundu kumadalira kwathunthu kukopa kwakumbuyo. Kuwunika kwa CCF (Cold Cathode Fluorescent Screen) ndiukadaulo wotchuka kwambiri womwe ungafikire 70% ndi 80% ya kukhutitsa utoto wa NTSC.

Ndiwonetsero yanji yomwe ili bwino?

　　 Chachitatu, m'magulu ogulitsa mafakitale, kusinthaku kumatha kuchitika zaka zisanu zilizonse kapena kupitilira apo. Kusintha kumachitika chifukwa kumafunikira kusintha kupita patsogolo kwaukadaulo kapena kukhala ndi mapangidwe abwino. Chifukwa chake, popanga zida zamafakitale ndi zamankhwala, ndikofunikira kwambiri kutero sungani kupitiriza kwinakwake, kuphatikiza mabowo omwe akukwera, malo olumikizira, komanso kukula kwake kofananira. Chiwonetserocho chikasintha mkati mwa zaka zisanu, chomaliza chimatha kukhala ndi zaka 10. Musanasankhe chowunikira, zimathandiza kulingalira za miyezo ndi malongosoledwe ake, komanso njira yopangira kampani. Mosiyana ndi izi, mawonedwe ogula amatha kusinthidwa miyezi isanu ndi umodzi iliyonse, zomwe zimawapangitsa kukhala kovuta kugwiritsa ntchito mapulogalamu omwe amafunikira kuwongolera kasinthidwe.

　　Musanasankhe chiwonetsero cha mafakitale, muyenera kulingalira mwatsatanetsatane ndi kapangidwe kamakampani, ndikusankha chiwonetsero choyenera kwambiri cha mafakitale.
