Display devices are electronic screens that present visual information to users. Common types include LCD (Liquid Crystal Display), LED (Light Emitting Diode), and OLED (Organic Light Emitting Diode) screens. These devices are used in various applications, such as televisions, computer monitors, and smartphones, allowing users to view images, videos, and text. The primary function of display devices is to convert electrical signals into visible images. They vary in size, resolution, and technology, impacting the quality of the displayed content.
