Answer

Brief Explanations:

Digital television displays images using pixels that can be turned on and off to represent different colors and intensities. Vacuum - tube technology is more associated with older analog TVs. A network of stations is involved in signal transmission but doesn't define the core operation of digital TV at the display level. Showing a sequence of film over a light source is how traditional film projection creates the illusion of movement, not digital TV.

Answer:

D. uses pixels that can be turned on and off.
