## FAQs
### Q: What is an active-matrix liquid-crystal display (AMLCD)?
A: An active-matrix liquid-crystal display is a **type of flat-panel display**. It is a **kind of liquid-crystal display (LCD)**, which uses the light-modulating properties of liquid crystals.

### Q: Is AMLCD the same thing as an LCD?
A: AMLCD is **a subclass of LCD**, meaning it is a specific type within the broader category of liquid-crystal displays. Both fall under display technologies that use liquid crystals to modulate light.

### Q: What are other names for active-matrix liquid-crystal display?
A: Common alternative names include **AMLCD** and **Aktiv-Matrix-LCD**. It is also referenced by names in multiple languages, including **有源矩阵液晶显示器** and **주동/능동형 액정 표시장치** (as listed in the aliases).

### Q: Where can I find a general reference link associated with AMLCD?
A: One listed “described at” URL is an IEEE page: **https://www.ieee.org/about/news/2011/honors_ceremony/releases_nishizawa.html**. The provided metadata indicates it is in English and was accessed on **2017-10-18**.

## Why It Matters
Active-matrix liquid-crystal display (AMLCD) matters because it represents a recognized category within **flat-panel display** technology and sits within the broader family of **liquid-crystal displays (LCDs)**. As a subclass of LCD, it is part of the ecosystem of displays that rely on the **light-modulating properties of liquid crystals**, a foundational mechanism for many modern screen types. In knowledge organization terms, AMLCD is also linked (per the provided structured properties) to the classification of an **appliance/computer appliance**, which can matter for cataloging, product taxonomy, and technical documentation workflows. For information retrieval and interoperability, AMLCD’s multiple aliases across languages (including English, Chinese, and Korean forms) and its cross-database identifiers (KBpedia and Freebase) help systems map the same concept across datasets and multilingual sources. This improves search, entity linking, and consistent labeling in knowledge bases and documentation.

## Notable For
- Being explicitly categorized as a **type of flat-panel display**.
- Being a **subclass of liquid-crystal display (LCD)**, tying it to liquid-crystal light modulation as its underlying display principle.
- Having **multilingual aliases** (including Chinese and Korean forms) that support cross-language entity matching.
- Having cross-knowledge-base identifiers, including **KBpedia (ActiveMatrixDisplay)** and **Freebase (/m/017tnm)**.
- Having a dedicated Wikipedia entry titled **“Active-matrix liquid-crystal display”** with multiple language editions.
