3. Ukusetshenziswa kokukhanyisa kwe-LED kumidiya emisha yangaphandle
Okokuqala, kunezindlela ezimbili ezihlukanisayo kumidiya entsha yangaphandle. Eyodwa iwumkhuba wokuthandwa ngabantu, kanti enye iwumkhuba wokuhlukanisa kakhulu.
Selokhu kwavela i-Focus, wonke umuntu usewamukele ngokuphelele umqondo wokuhlukaniswa, ngezinye izikhathi kuze kube sezingeni lokuchichima. Imithombo yezindaba emisha yanamuhla ngokuyinhloko iyimithombo yezindaba, etholakala ikakhulukazi ezindaweni zokuxhumana nezilaleli.
Yonke indawo yokuthinta ingase ikhiqize imidiya entsha. Kufanele kushiwo ukuthi ukuhlukaniswa ngokweqile kuye kwabangela ukunengeka phakathi kwezilaleli.
Eminyakeni emibili noma emithathu edlule, kungase kube noshintsho olukhulu kule mboni, futhi izitayela eziningi zokuhlukaniswa sezifinyelele esiphethweni esithile.
Ngaphezu kwalokho, kunomkhuba wokuduma, ikakhulukazi ezindaweni zomphakathi ezivalekile. Umkhuba wokuduma uzoba sobala kakhulu eminyakeni embalwa edlule.
Eminyakeni emibili noma emithathu edlule, ukukhiqizwa okukhulu kwemidiya emisha ehlukene kungase kuholele ekuhlanganisweni okukhulu. Lapho izinto ziba ngokwedlulele, kungase kube nenqubo yokuhlanganiswa komunye nomunye.
Okwesibili, ngokombono wokucabangela, eminyakeni eyi-10 ezayo, emadolobheni amakhulu, imithombo yezindaba yangaphandle yendabuko ingase ithathelwe indawo amafomu amasha njengevidiyo yangaphandle ne-LED yangaphandle.
Njengoba sonke sazi, izethameli zichitha isikhathi esiningi zingaphandle. Imidiya yangaphandle yendabuko imayelana nomqondo wamaphuzu. Eqinisweni, isikhathi sokukhava kanye nesethameli sokuhlala sincane uma kuqhathaniswa.
Ngesikhathi esifanayo, ubuchwepheshe obusha emkhakheni wezindaba zangaphandle busebenza ngokulinganayo futhi buthuthuka ngokushesha, okuzothuthukisa ukukhula nokuvuthwa kwemidiya emisha.
Ukukhula kokukhangisa kwangaphandle kuvela ikakhulukazi kuvidiyo yangaphandle ne-LED yangaphandle. I-TV ehambayo kwezokuthutha umphakathi inyuke ngamaphesenti angaphezu kuka-200 ngo-2007 uma kuqhathaniswa no-2006, futhi izinga lokukhula kwe-LED yangaphandle nalo lalimangalisa, lafinyelela ku-148%.
Okwesithathu, ukwahlulelwa kwabezindaba ezintsha kungase kuhluke kakhulu kulokho kwabezindaba zendabuko. Imidiya yendabuko incike kakhulu ethonyeni lokuqukethwe ukuze ithole ukukhuphuka noma impumelelo eqhubekayo.
Kunezici ezine ezithinta impumelelo eqhubekayo yemithombo yezindaba emisha yangaphandle, okuyizinsiza zesiteshi, ubuchwepheshe, imali kanye nomkhiqizo.
