1. What Is the NovaStar A7s Plus?
The NovaStar A7s Plus is an LED receiving card for use inside LED display cabinets. It works as the link between the sending controller and the LED modules, receiving video data through Ethernet and delivering control signals to the hub board.
In a typical LED control system, the receiving card operates at the cabinet level. Each cabinet contains one or more receiving cards, depending on its size and design. The A7s Plus is designed for general-purpose use and supports different types of LED driver ICs, which allows it to be applied across a wide range of indoor LED display configurations.

3. Core Features
The NovaStar A7s Plus focuses on keeping the image consistent and the system stable at the cabinet level. Most of its features are designed to solve common problems seen in indoor LED displays, rather than adding complex configuration options.
- Image Consistency and Color Control
The A7s Plus supports pixel-level brightness and color calibration when used with NovaStar calibration tools. This helps reduce visible differences between cabinets, especially on dark scenes or solid colors. Individual RGB gamma adjustment is also supported, which improves grayscale performance at low brightness. With 18bit+ processing, gradients appear smoother and banding is less noticeable.
- Practical Adjustment During Installation
Dark or bright lines can appear at cabinet seams after installation. The A7s Plus provides a quick adjustment function to correct these issues directly on site. It also supports multi-batch adjustment, which is useful when LED modules from different production batches are used in the same screen.
For layout flexibility, the card supports image rotation in 90-degree steps. It can also work with compatible controllers to support 3D output when required by the project.
- Stability and Basic Redundancy
For long-running displays, the A7s Plus supports dual card backup and loop backup. These features help keep the screen running if a receiving card or signal cable fails. Basic monitoring functions, such as Ethernet status detection and temperature or voltage feedback, assist with daily maintenance without adding complexity to the system.
4. Typical Applications
The NovaStar A7s Plus is typically used in indoor LED display projects where stable operation and consistent image quality are required. Common application scenarios include:
- Indoor fixed LED displays
Suitable for installations that run for long periods and do not require frequent cabinet changes, such as permanent walls or information displays.
- Commercial and corporate displays
Used in retail spaces, corporate lobbies, and conference rooms where clean images and uniform brightness are important.
- Control rooms and monitoring centers
Appropriate for environments that require stable operation, predictable performance, and easy maintenance over time.
- Screens with small to medium cabinet sizes
The loading capacity of the A7s Plus matches many standard indoor cabinet designs, making it practical for common pixel pitches and layouts.
Overall, the A7s Plus is chosen for projects that prioritize reliability, image consistency, and straightforward system management, rather than extreme resolution or frequent structural changes.
