戶外數字標牌的IP等級: IP44與IP65選擇指南

部署時戶外數字標牌,防止灰塵,雨水和環境暴露與顯示性能一樣重要。 對於安裝在公共場所的商用LCD標牌,選擇正確的IP等級直接影響system reliability, lifespan, and maintenance cost.

本指南解釋了IP評級如何在商業數字標牌中工作,比較IP44和IP65作為典型的參考水平,並幫助您為Qtenboard戶外數字標牌項目選擇正確的保護標準。

IP代表入口保護,由定義的標準國際電工委員會 (IEC)表明電氣設備的防塵防水性能。

An IP rating consists of two digits:
第一個數字 (防塵): 耐固體顆粒
第二位數字 (水保護): 耐潮濕和水暴露

For commercial digital signage displays, commonly referenced ratings include:
IP44: Basic protection against solid objects and water splashes
IP65: 全防塵和強大的抗雨水和水射流

在戶外數字標牌應用中-例如廣告顯示,街道引導系統和智能城市信息屏幕-IP等級確保在不斷變化的天氣條件下穩定運行.

對於企業投資戶外LCD數字標牌,圖像質量和屏幕尺寸很重要-但環境保護至關重要。

合適的IP等級有助於:
• 保護內部組件免受灰塵和濕氣的影響
• Ensure continuous operation in outdoor or semi-outdoor environments
• 減少設備故障、停機時間和長期維護成本
• 延長商業標牌系統的使用壽命

比較時IP44和IP65,區別不僅僅是技術上的-它直接影響waterproof outdoor digital signage解決方案可以在實際條件下可靠運行.

IP44和IP65只是商業顯示設備中使用的更廣泛的IP評級系統的一部分。

防塵等級 (0-6)

4-5級: 有限的防塵性能,適用於受控環境
6級: 完全防塵,recommended for outdoor digital signage

水保護等級 (0-9)

4級: 防濺,通常用於室內或遮蔽裝置
Level 5–6: Rain-resistant, 戶外LCD標牌的理想選擇
Level 7–9: Designed for immersion or extreme environments

Compared to lower ratings, IP65-rated outdoor digital signage displays provide stronger protection against rain, wind, and airborne dust commonly found in public outdoor spaces.

There is no single “best” IP rating—only the right rating for the application scenario.

Indoor or Semi-Indoor Digital Signage

For locations such as shopping malls, corridors, and covered commercial areas:
• Basic IP protection may be sufficient
• Lower protection levels help control project costs
• Suitable for indoor commercial digital signage displays

Outdoor Commercial Digital Signage

For open-air environments, including:
• Street-side advertising screens
• Smart city information displays
• Outdoor wayfinding and transportation signage
A higher IP rating is recommended. IP65-rated outdoor digital signage offers reliable performance under rain, dust, and fluctuating weather conditions, making it the preferred choice for long-term outdoor installations.

For Qtenboard outdoor digital signage solutions, IP65 is commonly adopted to ensure durability and stable operation in demanding environments.

Selecting the appropriate IP rating for commercial digital signage depends on three key factors:

Installation location

Indoor, semi-outdoor, or fully exposed outdoor environments

Environmental conditions

Exposure to rain, dust, humidity, wind, or pollution

Protection requirements and budget

Higher IP ratings offer stronger protection but involve higher costs

As an experienced manufacturer of commercial and outdoor digital signage, Qtenboard provides professional guidance to match IP protection levels with real project needs. For harsh or specialized environments, customized waterproof digital signage solutions with higher protection standards (such as IP67 or above) can be developed to meet specific requirements.
