These devices digitize an image or document. The digitization of the image is stored as a file that can be displayed, printed, or altered. A bar code reader is a type of scanner that reads Universal Product Code (UPC) bar codes. It is widely used for pricing and inventory information.

Plasma displays are another type of flat panel monitor that can achieve high levels of brightness, deep black levels, and a very wide range of colors. Plasma displays can be created in sizes of up to 150 inches (381 cm) or more. Plasma displays get their name from the use of tiny cells of ionized gas that light up when stimulated by electricity.

An organic LED display uses a layer of organic material that responds to electrical stimulus to emit light. This process allows each pixel to light individually, resulting in much deeper black levels than LED. OLED displays are also thinner and lighter than LED displays.

Televisions are also output devices, but may have input capabilities. A Smart TV runs an operating system which allows it to receive input from the user and connect to many content sources over the Internet and from smartphones, tablets, and other connected devices. Using a Smart TV virtually eliminates the need for a set-top box. A set-top box is a device which connects a standard TV to content sources such as a cable, satellite, or streaming.

Digital Light Processing (DLP) is a projection technology. DLP projectors use a spinning color wheel with a microprocessor-controlled array of mirrors called a digital micromirror device (DMD). Each mirror corresponds to a specific pixel. Each mirror reflects light toward or away from the projector optics. This creates a monochromatic image of up to 1024 shades of gray in between white and black. The color wheel then adds the color data to complete the projected color image.
