Passage Summary: New TV screens are made of tiny tiles. Unlike regular thin TVs that get dimmer if you make them bigger, these tiled TVs can be huge and stay bright and thin.

Reasoning: Standard thin screens dim as they get larger, but compound screens use small, bright tiles that can be added indefinitely without losing brightness or increasing thickness.

Analysis: This is a 'Must be True' question, so we must treat the technical specifications as absolute facts. The key contrast is that standard technology has a size-to-brightness trade-off that compound technology lacks. Look for an inference that combines these facts—specifically, that a very large, thin, and bright screen is possible with compound technology in a way that it is not with standard noncompound technology.
