I-TV ene-cathode-ray tube
Amamodeli ama-TV amaningi kunawo wonke avela ezitolo zemishini yasendlini - ejwayelekile kuwo wonke amadizayini, isithombe esisesikrinini sabo senziwa nge-tube ye-cathode ray. Ibanga ukusuka ku-TV yalesi model kuya emehlweni kumele okungenani libe ngamamitha angu-2-3. Uma ibanga lingaphansi, khona-ke ubungozi obungozi obukhulu emehlweni akho.
I-LCD, i-LED ne-TV yama-TV
I-LCD (i-crystal liquid) nama-TV ama-plasma kubhekwa njengendlela ephephile kakhulu. Uma zibukwa, amehlo awahlukunyezwa ngokuchofoza, ngoba akakho ngokuphelele. Ibanga eliphephile le-TV ye-LCD ingaba yinto engavamile, ayinayo imishanguzo enobungozi, ngakho-ke ungawabuka kusukela kunoma iyiphi ibanga elihle. Awukho umehluko phakathi kwebanga eliphephile kanye nochungechunge lwe-TV kusuka ochungechungeni lwe-LED.

Ososayensi baseNtshonalanga bafika kulo mbono emva kokuhlolwa okuningi kwamavolontiya. Naphezu kokuthi lezi zidingo zibhekiswe ikakhulukazi ezinhlobonhlobo zakudala zeTV TVs, akufanele usayinaki amehlo akho, ubukela imibukiso ye-TV eduze kwesibuko.
Umshini wokubala wokubala ibanga eliqondile lokubuka lolu hlobo lwe-TV lunikezwa etafuleni:
I-3D TV: ukubala ibanga
Ungabuka ama-movie ngefomethi ye-3D namhlanje ngaphandle kokushiya ikhaya lakho. Ukuze uzicwilise ngokuphelele ezenzakalweni ezenzeka esikrinini, kunconywa ukuthi ungahlali kude ne-TV, kodwa ngeke yini kulimaze umbono? Ochwepheshe baqinisekisa ukuthi ukubukela amabhayisikobho ngefomethi ye-3D akulimazi neze umonakalo womuntu. Ibanga elingcono le- screen TV ye - 3D yinkomba elingana namamitha amathathu, futhi i-angle enconyiwe ye-TV kufanele ibe ngaphansi kwe-60 °. Uma ulandela lezi zincomo, imiphumela yombukiso wevidiyo ku-3D izosondelana nalokho ongakubona ku-movie. Qinisekisa ukuthi ucabangela ikhwalithi (ukuxazulula) kwento yevidiyo. Uma ukulungiswa kwevidiyo kufikela ku-720p, kufanele ube khona esikrinini kude kumamitha amathathu, futhi uma ngabe ngu-1080p, ibanga elingcono kakhulu lingamamitha amabili.
