在快速发展的数字标牌世界中，可折叠海报LED显示屏已成为寻求最大化空间利用和适应多种场景的企业的灵活解决方案——从零售快闪店和展览展位到临时促销活动。在众多多功能选项中，640mm×1920mm的可折叠海报LED显示屏因其平衡的比例（非常适合展示产品和品牌故事等垂直内容）和节省空间的设计而脱颖而出。本指南重点介绍如何利用这一特定尺寸，强调可折叠技术的优势，并概述如何获取详细的规格表。

Part 1: 640mm×1920mm 可折叠海报 LED 显示屏的核心优势

Before diving into selection, understanding why this size and foldable feature matter is key to unlocking its value:

1. 垂直内容的最佳比例

The 640mm×1920mm dimension follows a vertical (portrait) aspect ratio, perfectly suited for the content most businesses prioritize:

Product highlights**: Ideal for showcasing apparel, cosmetics, or electronics—vertical layout aligns with how customers naturally view single-item displays.

Promotional messages**: 纵向空间允许多行文本、高分辨率图像或短的垂直视频（例如，“限时优惠”或品牌故事）而不裁剪。

空间效率**：在零售过道、商场走廊或快闪展位角落等狭窄区域，640mm的宽度无缝适配，而1920mm的高度确保了可见性而不压迫周围空间。

2. 可折叠设计：适应动态场景的灵活性

The foldable feature addresses common pain points of traditional fixed-size displays:

易于运输**：折叠成紧凑的形状（通常减少50%或更多的体积），消除了对大型运输箱的需求——非常适合举办外部活动的企业（例如，贸易展览、路演）。

Quick setup & teardown**: No complex assembly tools required; most models can be unfolded and mounted in 15–30 minutes, saving time for temporary promotions or pop-up stores.

Storage savings**: When not in use, folded displays take up minimal space (e.g., fitting in office storage closets or retail backrooms), avoiding the clutter of large fixed screens.

Adaptable installation**: Works for both temporary setups (e.g., hanging from event tents) and semi-permanent use (e.g., retail windows)—the foldable structure doesn’t compromise stability during operation.

Part 2: Key Specifications to Check for 640mm×1920mm Foldable Models

为了确保显示满足您的需求，请关注这些不可妥协的技术规格——量身定制的640mm×1920mm尺寸和可折叠设计：

1. 像素间距：平衡清晰度和成本

Pixel pitch determines how sharp content appears, especially for the vertical 640mm×1920mm layout:

短距离观看（1-2米，例如，快闪店柜台）：选择P1.5-P2.0像素间距。这确保了文本（例如，产品描述）和细节（例如，面料纹理）清晰，即使顾客站得很近。

中等距离观看（2–5米，例如，商场走廊）**：P2.5–P3.0的点间距是最佳选择。它为路过的行人保持清晰，同时保持显示的成本效益——非常适合观众快速移动的高流量区域。

2. 亮度：匹配环境

Brightness (measured in nits) must align with where the display will be used, as the 640mm×1920mm vertical size is often placed in visible, well-lit spots:

室内低光照（例如，精品试衣间、活动帐篷）**：300–400 nits。防止眼睛疲劳，同时保持内容可见。

Indoor bright-light (e.g., retail windows, mall atriums)**: 500–700 nits. Counters ambient light (including sunlight through windows) to avoid washed-out images.

Semi-outdoor (e.g., covered market stalls, outdoor pop-ups)**: 800–1000 nits. Ensure the model has weather resistance (e.g., splash-proof coating) to pair with brightness.

3. 可折叠机制与耐用性

由于可折叠性是一个核心特征，请验证这些设计细节以避免磨损：

Folding joint material: Look for aluminum alloy or reinforced plastic joints—these resist bending damage even with frequent folding (aim for 1,000+ fold cycles without issues).

Protective layers**: 屏幕表面应具有抗划伤涂层（例如，钢化玻璃或抗划伤膜），因为折叠显示屏可能会被放在包或盒子中运输。

Weight**: A well-designed 640mm×1920mm foldable model should weigh 15–20kg. This balance ensures portability (one person can carry it) and stability during use.

4. 电源与连接性

For flexibility in temporary setups, check these practical specs:

Power options: Models with built-in rechargeable batteries (8–12小时的使用时间每次充电) are ideal for events without easy access to outlets. For semi-permanent use, AC power (100–240V) works best.

连接性：确保支持常见接口，如 HDMI、USB 和 Wi-Fi。Wi-Fi 对于远程内容更新尤其有用（例如，改变促销而无需在现场）。

Part 3: 如何获取可折叠海报LED显示屏规格表

Without brand references, focus on universal, reliable channels to get detailed specs for 640mm×1920mm foldable models:

1. 行业特定的B2B平台

Many manufacturers list foldable poster displays on global B2B platforms. To find specs:

1. 在像 Made-in-China.com、Global Sources 或 TradeKey 等平台上搜索“640mm×1920mm 可折叠海报 LED 显示屏”。

2. 通过“认证供应商”筛选结果（以确保可信度）。

3. 通过平台的消息系统联系供应商，请求“640mm×1920mm可折叠LED海报显示器的详细规格表”。明确您的需求（例如，“用于零售快闪店”或“半户外使用”），以获取量身定制的文档。

2. LED显示器制造商官方网站（一般搜索）

Instead of specific brands, use generic search terms to find manufacturer sites:

- 搜索引擎：在 Google、Bing 或 Yahoo 中输入 "640mm×1920mm foldable poster LED display manufacturer"。

- Navigate to "产品" or "可折叠显示器" sections on manufacturer sites.

- Look for "技术数据表" 或 "规格" 下载——大多数将有 PDF 文件详细说明尺寸、像素间距、亮度和可折叠特性。

3. 展会与行业活动

Attend global LED or signage trade shows (e.g., Sign & Digital UK, FESPA Global Print Expo) to connect with manufacturers directly:

- Visit booths showcasing foldable LED displays and ask for physical specification booklets for 640mm×1920mm models.

- Demo the displays in person to test foldability, brightness, and clarity—then request digital specs via email for follow-up.

Part 4: 640mm×1920mm 可折叠模型的应用场景

为了最大化此尺寸的价值，以下是其最佳使用案例：

零售快闪店：可折叠以便于运输到临时地点（例如，周末市场），然后展开以垂直格式展示新系列。

Exhibition booths: 节省了与固定屏幕相比的展位空间，同时1920毫米的高度确保品牌内容在邻近展位中脱颖而出。

Temporary promotions: Used in mall kiosks or store entrances for limited-time sales—folded and stored when the promotion ends.

Event signage: Serves as directional signs (e.g., "Workshop Hall A") or promotional displays at conferences, with battery power enabling placement anywhere.

选择640mm×1920mm可折叠海报LED显示屏的关键在于将其技术规格与您的使用案例对齐——优先考虑像素间距以适应您的观看距离，亮度以适应您的环境，以及耐用的可折叠机制以便于携带。通过使用B2B平台、制造商网站或贸易展会获取详细的规格表，您可以验证显示屏是否满足您的需求，并解锁节省空间、适应性强的数字标牌解决方案的灵活性。
