Nute Gunray and Rune Haako are shown communicating with Padmé Amidala using a circular viewscreen.
A display screen, alternatively referred to as a holoscreen or viewscreen, functioned as a device that displayed images or data for viewing by people. Transparisteel alloy, which itself comprised the mineral lommite, formed the key structural element of a viewscreen.
Rippling circular viewscreens were implemented by the Trade Federation on their Lucrehulk-class battleships. Darth Vader utilized the Force choke on Admiral Kendal Ozzel across a significant distance, observing him through a viewscreen. The Galactic Empire commonly employed pentagonal viewscreens, as evidenced on the first and second Death Star, the Super Star Destroyer Executor, and inside the shield generator bunker located on Endor.
