Which of the following characterizes LCD displays?

LCD displays, or liquid crystal displays, are characterized by incorporating separate colored pixels arranged together to form images. Each pixel in an LCD consists of subpixels that typically include red, green, and blue components. By varying the intensity of these subpixels, a wide range of colors can be produced. This technology allows for higher resolutions and better image quality compared to displays that might use a single color or a more limited method of color production.

The other options do not accurately represent characteristics of LCD technology. For example, LCDs are generally lightweight and thin, contrary to the implication that they are heavy and thick. They do not exploit only one primary color; rather, they utilize multiple colors to create the full color spectrum. Lastly, while some displays are solar-powered, traditional LCDs rely on electronic power sources, not directly on solar energy. These factors highlight why the incorporation of separate colored pixels is a defining feature of LCD displays.
