## Summary
A flat-panel display is an electronic visual display device characterized by a flat form factor. It serves as an output device for the presentation of information in visual form and encompasses various technologies including liquid-crystal and plasma displays.

## Key Facts
- Classified as a subclass of electronic visual display, display device, and display technology.
- Identified by the International Electrotechnical Vocabulary (IEV) number 845-32-036.
- Includes specific technology types such as liquid-crystal display (LCD), plasma display, and field emission display.
- Utilized in consumer electronics including flat-panel TVs and LCD television sets.
- Associated with the Common Procurement Vocabulary (CPV) code 30231310.
- Recognized by major authority files including the Library of Congress (sh2005001973) and the National Library of Israel.
- Features specialized implementations like LED-backlit LCD displays and liquid crystal on silicon.

## FAQs
### Q: What technologies are used in flat-panel displays?
A: Flat-panel displays utilize several distinct technologies to produce images, including liquid-crystal displays (LCD), plasma panels, field emission displays, and liquid crystal on silicon. Some implementations also use LED-backlighting to enhance the display.

### Q: How are flat-panel displays classified?
A: They are classified as electronic visual displays and output devices. Technically, they are defined by their flat form factor and are categorized under display technology in systems like the Library of Congress and KBPedia.

### Q: What is the difference between a flat-panel display and an LCD?
A: While the terms are often used interchangeably in consumer contexts, technical classifications sometimes distinguish the general "flat-panel display" category from the specific "liquid-crystal display" technology. LCD is one specific method used to create a flat-panel form factor.

## Why It Matters
Flat-panel displays represent a fundamental shift in how visual information is presented and consumed. By moving away from bulkier form factors, these devices enabled the development of slim television sets, portable computer monitors, and high-resolution color displays. They serve as the primary interface for a vast array of modern electronics, from household entertainment systems to professional information displays.

The technology's significance is reflected in its extensive documentation across global knowledge bases, including the Encyclopedia of China, Larousse, and Britannica. Its standardization through IEV numbers and procurement codes indicates its critical role in international trade and technical manufacturing. By integrating various light-modulating properties—such as those found in liquid crystals—flat-panel displays have become the standard for visual output in the digital age.

## Notable For
- **Diverse Technology Integration:** It serves as a parent class for multiple distinct display methods, including plasma and field emission.
- **Standardized Technical Identity:** It is uniquely identified in global engineering and procurement systems via IEV 845-32-036 and CPV 30231310.
- **Broad Application Range:** It is the foundational technology for both general-purpose flat-screen TVs and specialized color flatpanel displays.
- **Global Academic Recognition:** It is featured as a "Vital Article" (Level 4) on Wikipedia and is indexed in major academic databases like JSTOR and Microsoft Academic.

## Body

### Classification and Hierarchy
Flat-panel displays are defined as electronic display devices in a flat form factor. They belong to the broader classes of display devices and electronic visual displays. Within this hierarchy, they are further categorized into specialized types:
*   **Color flatpanel display:** Electronic color devices in a flat form factor.
*   **LED-backlit LCD display:** A specific implementation of display technology.
*   **Flat-panel TV:** Television sets specifically designed with a flat screen.

### Technical Implementations
The category encompasses several distinct technological approaches to visual output:
*   **Liquid-Crystal Display (LCD):** Displays that utilize the light-modulating properties of liquid crystals.
*   **Plasma Display:** A specific type of flat panel technology.
*   **Field Emission Display (FED):** A type of display technology categorized under the flat-panel umbrella.
*   **Liquid Crystal on Silicon (LCoS):** A technology using liquid crystal on a silicon backplane.

### International Standards and Identifiers
The entity is recognized across various international classification systems:
*   **IEV Number:** 845-32-036 (International Electrotechnical Vocabulary).
*   **CPV Code:** 30231310 (Common Procurement Vocabulary).
*   **YSO ID:** 17960.
*   **Library Authorities:** Library of Congress (sh2005001973) and National Library of Israel (987007544627705171).

### Consumer and Industrial Use
Flat-panel technology is the primary component in modern television sets, specifically LCD televisions. It is also documented in various educational and reference works, such as Wikikids (under "Flatscreen") and the Encyclopedia of China (Third Edition).
