Final answer:
The statement is true; individual matrix boxes on a digital display are known as pixels, which are responsible for generating the full range of colors we see on the screen by combining red, green, and blue subpixels.
Step-by-step explanation:
The statement that individual matrix boxes are known as pixels is true. Each pixel is a small unit of a digital image or display and is made up of subpixels, typically red, green, and blue, that combine to produce a full range of colors. When viewing a closeup of a flat screen, you can see the multitude of individual pixels and their color components. In modern displays, pixels are used to control the light and subsequently produce the required image for the viewer.
