Kodi khoma lamavidiyo ndi chiyani, limagwiritsidwa ntchito kuti, mitundu ndi cholinga

Makoma a kanema ndi “ma TV” osonkhanitsidwa kuchokera ku mapanelo ofanana a LCD, ma TV kapena zowunikira, zolumikizidwa muzithunzi. Tsopano amagwiritsidwa ntchito m’madera a maphunziro, bizinesi, zosangalatsa – kulikonse kumene kuli kofunika kusonyeza zambiri pawindo lalikulu.

Makoma a kanema ali ndi magawo angapo omwe amawayika:

1. Kutalika kwa swing . A diagonal 46 kapena 55 cm amadziwika ngati tingachipeze powerenga, wokhoza kugwira ntchito usana kwa zaka zingapo. Kutalika kwa nthawi yogwira ntchito kumasiyanitsa mapanelo amakanema ndi ma TV osavuta.
2. Chiwerengero cha ma module . Odziwika kwambiri ndi makoma a kanema a 2×2 mwa ma monitor anayi kapena makoma a kanema a 3×3 mwa asanu ndi anayi.
3. Kukula kwa msoko . Kusiyana kopitilira 5.3 mm kumawonedwa ngati kosatheka komanso kwakanthawi – izi sizimapangidwa lero. Zitsanzo zamakono zili ndi seam pakati pa 1.7 ndi 3.6 mm ndipo zimatengedwa ngati “zopanda msoko”.
