Electronic visual display in the context of Display server

A flat-panel display (FPD) is an electronic display used to display visual content such as text or images. It is present in consumer, medical, transportation, and industrial equipment.

Flat-panel displays are thin, lightweight, provide better linearity and are capable of higher resolution than typical consumer-grade TVs from earlier eras. They are usually less than 10 centimetres (3.9 in) thick. While the highest resolution for consumer-grade CRT televisions was 1080i, many interactive flat panels in the 2020s are capable of 1080p and 4K resolution.

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 that is supplied has an electrical signal the display is called an electronic display.

Common applications for electronic visual displays are television sets or computer monitors.

A computer monitor is an output device that displays information in pictorial or textual form. A discrete monitor comprises a visual display, support electronics, power supply, housing, electrical connectors, and external user controls.

The display in modern monitors is typically an LCD with LED backlight, having by the 2010s replaced CCFL backlit LCDs. Before the mid-2000s, most monitors used a cathode-ray tube (CRT) as the image output technology. A monitor is typically connected to its host computer via DisplayPort, HDMI, USB-C, DVI, or VGA. Monitors sometimes use other proprietary connectors and signals to connect to a computer, which is less common.

A touchscreen (or touch screen) is a type of display that can detect touch input from a user. It consists of both an input device (a touch panel) and an output device (a visual display). The touch panel is typically layered on the top of the electronic visual display of a device. Touchscreens are commonly found in smartphones, tablets, laptops, and other electronic devices. The display is often an LCD, AMOLED or OLED display.

A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus or one or more fingers. Some touchscreens use ordinary or specially coated gloves to work, while others may only work using a special stylus or pen. The user can use the touchscreen to react to what is displayed and, if the software allows, to control how it is displayed; for example, zooming to increase the text size.

An electronic document is a document that can be sent through non-physical means, such as telex, email, and the internet. Originally, any computer data were considered as something internal—the final data output was always on paper. However, the development of computer networks has made it so that in most cases it is much more convenient to distribute electronic documents than printed ones. The improvements in electronic visual display technologies made it possible to view documents on a screen instead of printing them (thus saving paper and the space required to store the printed copies). However, using electronic documents for the final presentation instead of paper has created the problem of multiple incompatible file formats. Even plain text computer files are not free from this problem—e.g. under MS-DOS, most programs could not work correctly with UNIX-style text files (see newline), and for non-English speakers, the different code pages always have been a source of trouble.

Even more problems are connected with complex file formats of various word processors, spreadsheets, and graphics software. To alleviate the problem, many software companies distribute free file viewers for their proprietary file formats (one example is Adobe's Acrobat Reader). The other solution is the development of standardized non-proprietary file formats (such as HTML and OpenDocument), and electronic documents for specialized uses have specialized formats—the specialized electronic articles in physics use TeX or PostScript.

In computing, text-based user interfaces (TUI) (alternately terminal user interfaces, to reflect a dependence upon the properties of computer terminals and not just text), is a retronym describing a type of user interface (UI) common as an early form of human–computer interaction, before the advent of bitmapped displays and modern conventional graphical user interfaces (GUIs). Like modern GUIs, they can use the entire screen area and may accept mouse and other inputs. They may also use color and often structure the display using box-drawing characters such as ┌ and ╣. The modern context of use is usually a terminal emulator.

An articulating screen is a built-in small electronic visual display which is not fixed, but rather can be repositioned using a hinge or pivot. The articulating screen is known under different other names such as flip-out screen, flip screen, adjustable screen, articulated screen, or hinged screen. According to the way it moves, there are five main types:

1. The display moves around one axis, so that it only tilts. It is called tilting screen or tiltable screen.
2. The display tilts horizontally both up and down and also vertically. This type is called double-hinged tilting screen, two-axis tilting screen, three-direction tilting screen or screen with 3-way tilt.
3. The display moves around two axes which are at a right angle to each other, so that the screen both tilts and swivels. This type is called swivel screen. Other names for this type are vari-angle screen, fully articulated screen, fully articulating screen, rotating screen, multi-angle screen, variable angle screen, flip-out-and-twist screen, twist-and-tilt screen and swing-and-tilt screen.
4. The display is mounted on a fully-articulating hinge that itself is attached to a tilting plate. Such display can be extended out from the back of the camera, ensuring it stays clear of the camera's left-mounted ports when flipping it out to the side. This type of articulating screen is called tilt-and-articulating screen.
5. The display moves into a variety of angles; it tilts horizontally and vertically and also rotates to a certain extent while staying aligned with the lens axis. It still can not be turned all the way up, down or to the side to be seen from the front of the camera for self-portraits. This type of articulating screen is called cross-tilt screen, flexible-tilt screen or flex-tilt screen.

Articulating screens are used in a variety of electronic devices such as laptops, camcorders, digital cameras, desk phones, mobile phones, DVD players and others; also TV screens and computer monitors can be articulating screens.

Digital signage is a segment of electronic signage that uses digital display technologies to present multimedia content in both public and private environments. Content may include video, images, text, or interactive media and is typically displayed for purposes such as advertising, information dissemination, branding, or entertainment.

Digital signage systems can be either networked or standalone. Networked systems are managed through centralized content management systems (CMS), often cloud-based, enabling remote updates, scheduling, real-time data integration, and dynamic content delivery. These systems may also incorporate audience analytics, IoT sensors, or AI-driven personalization.
