When delivering LED display projects, LEGIDATECH will flexibly select the most appropriate Huidu product based on customer needs.

Software Systems (HDPlayer, HDSet, HD2020, etc.)

Huidu provides a comprehensive software platform that supports various operations, including program editing, remote publishing, and scheduled playback.

Its simple and user-friendly interface allows average users to quickly learn without extensive training, making it ideal for the daily operation of commercial advertising screens or indoor information display screens.

When delivering a project, LEGIDATECH also provides the corresponding software version and installation package, allowing users to immediately run and manage content.

Control Card / Asynchronous Card (HD-A Series)

Huidu’s asynchronous cards are widely used in applications such as small advertising screens and doorway displays. They support remote content updates via Wi-Fi, mobile apps, or 4G networks, significantly reducing operating costs.

For clients with limited budgets who require real-time advertising updates, LEGIDATECH recommends the A series, offering low-cost yet highly flexible content management.

Receiver Card (HD-R Series)

Receiver cards are crucial for LED screen image quality. Huidu’s R series receiver cards are renowned for their high refresh rates, stable drive, and excellent color reproduction, making them particularly suitable for high-resolution applications like LEGIDATECH’s Ehonor indoor full-color display.

By matching the display’s depth with the screen, they ensure flicker-free images with rich depth, meeting the requirements of high-end indoor environments such as conference rooms, churches, and exhibition halls.

All-in-One Player/Controller (HD-VP Series)

The Huidu VP series integrates a transmitter card, video processor, and playback functions, supporting multiple signal inputs and video wall displays.

It’s particularly suitable for medium-sized indoor stages and conference centers.

LEGIDATECH frequently recommends this series for stage rental and fixed-installation screen projects. Customers only need a single device to complete video input, switching, and playback, significantly simplifying system setup and post-production operations.

IV. Typical Application Scenarios

The Huidu control system, due to its high cost-effectiveness and ease of use, is widely used in various indoor LED display projects.

When delivering displays, LEGIDATECH will select the most appropriate Huidu solution based on the specific scenario, ensuring a stable and cost-effective system. The following are a few common application examples:

When paired with the Huidu HD-R series receiver card, it fully utilizes the display’s performance, achieving smooth visuals and stable color rendering.

Furthermore, due to the Huidu system’s competitive price, customers can enjoy high-quality display while effectively controlling project costs.

Shopping Mall Advertising Screens

In centres commerciaux and other retail environments, advertising content requires frequent updates. The Huidu HD-A series control card supports remote content updates via Wi-Fi, mobile app, or 4G network.

Mall operators can easily perform changes without on-site intervention, significantly improving efficiency.

This type of solution offers low O&M costs and high flexibility, making it a popular choice among commercial customers. Meeting Room and Church Screens.

Conference and religious venues often require multiple input sources, such as computers, cameras, or multimedia players. The Huidu HD-VP series video processor integrates a transmitter card, video switching, and playback functionality into a single device.

It can quickly switch between multiple signal inputs while maintaining high-quality output, ensuring smooth presentations and live broadcasts.

LEGIDATECH has successfully implemented this solution in numerous church and corporate conference room projects.

Teachers and administrators can easily play courseware, schedule classes, and switch between content, making them ideal for educational applications.

How to Choose the Right Huidu System for Your Project

In LED display projects, different installation scales, application scenarios, and budgets all influence the choice of control system.

When configuring Huidu solutions for customers, LEGIDATECH typically considers multiple factors, including screen size, pixel pitch, input requirements, and O&M costs. The following are selection recommendations for several typical scenarios:

Small Screens (P4/P5 Doorway Screens)

For smaller doorway screens or banners, the display content typically consists primarily of text, images, or simple videos. These scenarios prioritize ease of installation and cost control, so we recommend the Huidu HD-A series asynchronous cards.

These cards support content updates via Wi-Fi or a mobile app, allowing operators to quickly change advertisements without specialized skills, greatly improving convenience.

Indoor Medium-Sized Screens (such as Ehonor P2.5 Indoor Screen)

For indoor medium-sized screens in conference halls, shopping malls, and exhibition halls, display quality and system stability are key requirements. We recommend the HD-R series receiving card and HD-VP video processor.

The HD-R receiving card ensures high refresh rates and excellent color reproduction, while the HD-VP series video processor supports multimedia input and splicing processing, ensuring efficient operation of medium-sized screens in various application scenarios.

Multiple Input Requirements (Conferences/Stage Performances)

When projects require the integration of multiple signal sources, such as computers, cameras, and video players in conference rooms, or multiple real-time inputs in stage performances, the Huidu HD-VP series is recommended.

It integrates a sending card, video switching, and splicing processing capabilities, enabling rapid switching between multiple signal sources while maintaining high resolution and stable output. It is ideal for applications requiring high real-time performance and image quality.

LEGIDATECH’s Application Experience

For small or medium-sized screen projects focused on commercial advertising, clients are often more concerned with cost and ease of use. For these scenarios, we recommend the HD-A control card and HDPlayer software combination.

The HD-A card is affordable, and when used with HDPlayer software, it easily handles program editing and scheduled playback, meeting all daily advertising needs. It’s a cost-effective and practical solution.

In LEGIDATECH’s Ehonor series indoor LED screen projects, over 80% of the screens are equipped with the Huidu system. This choice not only ensures a stable and detailed display, but also fully demonstrates Huidu’s advantages in the small and medium-sized indoor screen market.
