Which term describes the light-emitting components within display monitors?

• A. Picture element (pixel)
• B. Display element
• C. LED unit
• D. Luminescent cell

Answer: (A)

The light-emitting element that forms the image on a screen is called a pixel, short for picture element. A pixel is the smallest unit of a display that can be individually controlled to produce light and color, and millions of these tiny elements combine to create a full image. In color displays, each pixel typically contains red, green, and blue subpixels, and varying their brightness lets the screen show a wide range of colors. Even though some technologies use backlights or different light sources, the term pixel remains the standard way to describe the light-emitting component of a monitor. The other terms are less precise: a display element is too vague, an LED unit implies only LEDs, and a luminescent cell isn’t the conventional label used for monitor components.
