Product information

Description

DAHUA DHI-LDH55-LAI400L is a 55" digital signage flat panel with a 4K UHD (3840 × 2160) IPS VA LCD optimized for continuous public-display use. The panel delivers 500 cd/m² brightness and an 8 ms response time, runs Android 11 on a built‑in quad‑core processor, and includes integrated speakers and network connectivity. Designed for retail, corporate and information signage, the unit supports VESA mounting and offers industrial‑grade durability for long operating hours.

Advantages

The high‑resolution 4K LCD and IPS VA technology provide wide viewing angles and sharp visual detail suitable for close‑range and distant viewing. Android 11 and the onboard quad‑core CPU enable native app playback and smooth 4K decoding without requiring an external player. Built‑in speakers and network support simplify installation and content delivery, while the industrial‑grade panel and continuous operation design make the display suitable for prolonged public use.

Suitable for (tasks / use cases)

Retail digital advertising and promotional screens in stores and shopping centres
Corporate reception, meeting room schedules and internal information displays
Public information boards in transport hubs, museums and municipal facilities
Menu boards and point‑of‑sale signage in restaurants and cafés

When it may not be suitable

This flat panel is intended for indoor digital signage applications; it is not designed for outdoor use or exposure to direct weather conditions. It may be unnecessary for users who only require a basic office monitor without integrated signage management features or Android app support.

Key specifications

Display diagonal: 55" (139.7 cm)
Resolution: 3840 × 2160 (4K Ultra HD)
Panel type: IPS VA LCD
Brightness: 500 cd/m²
Response time: 8 ms
Operating system: Android 11 (built‑in)
Audio: built‑in speakers (integrated output)
Mounting: VESA compatible
Network: Ethernet LAN support for content and remote management
Continuous operation: industrial‑grade design for extended daily use
Colour: Black
Energy class (SDR): G; energy consumption (SDR) per 1000 h: 100 kWh

How to use

Install the display on a VESA‑compatible bracket or wall mount following standard mounting safety guidelines and ensure adequate ventilation. Connect power and an Ethernet cable for networked content management, or use local storage and Android apps to play media. Use the device’s management interface or a compatible signage platform to schedule, partition and distribute playlists; the device supports intelligent split‑screen layouts and timed program release. Adjust brightness and audio levels through the on‑screen menu to suit ambient conditions.

What to consider before purchase

Intended installation location (indoor use only, ensure adequate ventilation and mounting support)
Need for networked remote management versus local playback using Android apps
Ambient light levels to determine whether 500 cd/m² brightness meets visibility needs
Sound requirements — integrated speakers simplify audio but may be insufficient for large spaces
Energy efficiency (SDR class G) and expected operating hours when estimating power costs

Usage recommendations

For reliable operation, set up the display in a temperature‑controlled indoor environment, use wired Ethernet for stable content delivery, and employ the device’s split‑screen and scheduling features to maximise content flexibility. For larger venues or higher ambient light, consider complementary external audio or higher‑brightness solutions.
