An LCD screen is composed of a fixed grid of pixels. Pixels, short for "picture elements," are the smallest units of a digital image or display that can be controlled individually. Each pixel can represent a specific color and intensity, and when combined, these pixels create the images and graphics that we see on the screen.

The organization of pixels in a grid format allows for the precise rendering of images at various resolutions. The higher the number of pixels in a grid, the higher the resolution and, consequently, the sharper and more detailed the images will appear. This concept is fundamental in understanding how digital displays, including LCD screens, function and deliver visual content.

Other options like points, vectors, and cells do not accurately describe the structure of an LCD screen. Points are generally a measure of location or size in graphics, vectors are mathematical representations of direction and magnitude, and cells refer to individual compartments in a grid structure but do not specifically denote the tiny units that make up a display image. Thus, the most accurate term in the context of LCD screens is pixels.
