Understanding Pixels and Light

The video tutorial explains how monitors display images by using pixels, which are composed of small red, green, and blue dots. Each pixel contains a backlight, color filters, and a polarizer. The tutorial further describes how light travels through these components along different planes, including horizontal and vertical planes.
