Display Device

A Display Device is an output device that presents information in visual or tactile form for human perception and interaction.

AKA: Visual Display, Electronic Display, Screen, Monitor.
Context:
- It can present Visual Information through various technologies such as LCD, OLED, LED, CRT, and projection systems.
- It can render Content in different color depths, resolutions, and refresh rates to suit various applications.
- It can provide Tactile Output in specialized devices such as refreshable braille displays for visually impaired users.
- It can convert Electronic Signals into visible images or tactile patterns that can be perceived by humans.
- It can incorporate Touch Functionality to serve as both output device and input device.
- It can reproduce Static Content like text and images or dynamic content like video and animations.
- ...
- It can often feature Adjustable Settings for brightness, contrast, color temperature, and other display parameters.
- It can often include Protective Layers such as anti-glare coatings, scratch-resistant surfaces, and blue light filters.
- It can often provide multiple Input Ports like HDMI, DisplayPort, VGA, and USB-C for connectivity with various devices.
- It can often support various Aspect Ratios and scaling modes to accommodate different content formats.
- ...
- It can range from being a Monochrome Display to being a True Color Display, depending on its color reproduction capability.
- It can range from being a Small Form Factor Display to being a Large Format Display, depending on its physical dimensions.
- It can range from being a Low Resolution Display to being a High Definition Display, depending on its pixel density.
- It can range from being a Fixed Information Display to being an Interactive Display, depending on its input capability.
- It can range from being a 2D Display to being a 3D Display, depending on its dimensional rendering ability.
- It can range from being a Standard Dynamic Range Display to being a High Dynamic Range Display, depending on its contrast ratio and color gamut.
- ...
- It can integrate with Computer Systems to serve as primary visual interfaces for user interaction.
- It can connect to Mobile Devices for content consumption and application use.
- It can interface with Industrial Equipment for monitoring, control, and status indication.
- It can support Accessibility Tools for users with various visual impairments or special needs.
- It can interact with Media Players and Gaming Consoles for entertainment purposes.

Examples:
- Consumer Displays, such as:
  - Home Entertainment Displays, such as:
    - Television Screens, ranging from compact TV to large-format displays.
    - Computer Monitors, including gaming monitors and professional grade displays.
  - Mobile Displays, such as:
    - Smartphone Screens, utilizing OLED or LCD technology.
    - Tablet Displays, optimized for portable viewing experiences.
    - Laptop Screens, balancing portability and viewing quality.
  - Wearable Displays, such as:
    - Smartwatch Screens, designed for glanceable information and compact form factor.
    - VR Headsets, providing immersive visual experiences.
    - Heads-Up Displays, projecting information onto transparent surfaces.
    - Augmented Reality Glasses, overlaying digital content on real-world views.
- Professional Displays, such as:
  - Medical Displays, such as:
    - Diagnostic Monitors, with high precision for medical imaging.
    - Surgical Displays, designed for operating room environments.
  - Industrial Displays, such as:
    - Control Panel Displays, for machinery operation and system monitoring.
    - Ruggedized Displays, for harsh environments and outdoor use.
  - Specialized Displays, such as:
    - Refreshable Braille Displays, providing tactile output for blind users.
    - E-Paper Displays, mimicking the appearance of ordinary paper.
    - Public Information Displays, for wayfinding and information dissemination.
- ...
Counter-Examples:
- Input Devices, such as keyboards and mouses, which capture user input rather than display information.
- Audio Output Devices, such as speakers and headphones, which present information in auditory form rather than visual or tactile form.
- Projection Surfaces, which are passive mediums that receive projected images rather than active display devices.
- Static Print Materials, such as paper documents and posters, which cannot change their display content electronically.
- Cameras and Sensors, which capture information rather than display it.

- A display device is an output device for presentation of information in visual or tactile form (the latter used for example in tactile electronic displays for blind people). When the input information is supplied has an electrical signal, the display is called an electronic display.
  Common applications for electronic visual displays are televisions or computer monitors.
