Summary

Compound television screens are built by joining together small tiles that are each a separate miniature screen.

TVs with compound screens are just a few inches thick.

When the thickness of TVs with noncompound screens is held constant, the larger a screen is, the dimmer it is.

Each tile in a compound screen is small enough to retain brightness.

In compound screens, you can have an unlimited number of tiles joined together without making the screen less bright or the TV set thicker.

Notable Valid Inferences

For TVs with compound screens, having a larger screen doesn’t mean that the screen will be dimmer. These TVs can be bright and large.
