Electronic displays are devices that visually present information using various technologies. Common types include LCD (Liquid Crystal Display), LED (Light Emitting Diode), and OLED (Organic Light Emitting Diode). These displays are widely used in televisions, computer monitors, smartphones, and digital signage, providing clear and vibrant images. The functioning of electronic displays relies on the manipulation of light and color. For instance, LCD screens use a backlight to illuminate liquid crystals, while OLED screens emit light directly from organic compounds. This technology allows for high-resolution images and energy-efficient performance, making electronic displays essential in modern communication and entertainment.
