RFN05000A4 Series: Energy-Efficient 5-Inch IPS TFT LCD Modules for Demanding Industrial Environments

As embedded systems become more sophisticated, display requirements continue to grow. Developers need displays that combine excellent readability, wide viewing angles, robust temperature performance, and low power consumption. Raystar’s new RFN05000A4 Series addresses exactly these challenges with two 5-inch TFT LCD modules designed for industrial and intelligent embedded applications.

The series consists of:

RFN05000A4A0WHDNN00: High-brightness IPS TFT LCD module
RFN05000A4A0WWDNC00: IPS TFT LCD module with integrated Projected Capacitive Touch (PCAP)

Both modules feature a 5-inch diagonal display with 800 × 480 WVGA resolution, IPS technology, a 24-bit RGB interface, and support for operation in harsh environments from -30°C to +80°C.

Key benefits of RFN05000A4 Series

Designed for Industrial and Outdoor Visibility

The RFN05000A4 Series utilizes IPS (In-Plane Switching) technology, delivering wide viewing angles of 85° in all directions. This ensures consistent image quality and color reproduction, regardless of the user’s viewing position. Combined with a Normally Black, Transmissive TFT architecture, the modules provide excellent visual performance for modern HMI and control panel applications.

For environments with challenging lighting conditions, the RFN05000A4A0WHDNN00 offers an impressive 1000 cd/m² brightness level, making it suitable for outdoor or high-ambient-light installations where display readability is critical. The module also features an anti-glare surface treatment to further enhance visibility.

Significant Power Savings for Modern Embedded Designs

One of the most notable advantages of the RFN05000A4 Series is its focus on energy efficiency.

Compared with Raystar’s previous RFF500 Series products, the new RFN05000A4 family is optimized for lower power consumption:

The high-brightness RFN05000A4A0WHDNN00 can reduce power consumption by up to 30%
The PCAP-enabled RFN05000A4A0WWDNC00 can reduce power consumption by up to 60%

This combination of high performance and reduced energy requirements makes the series particularly attractive for energy-sensitive embedded designs, portable industrial equipment, and applications where thermal management and operating efficiency are important design considerations.

Integrated Touch Functionality for Advanced HMI Systems

For applications requiring interactive user interfaces, the RFN05000A4A0WWDNC00 incorporates a Projected Capacitive Touch Panel (PCAP). The touch system is based on the GT911 touch controller and supports up to 5 simultaneous touch points via an I²C interface.

This makes the module an excellent choice for:

Smart access control panels
Industrial handheld devices
Agricultural equipment
Portable diagnostic instruments
Intelligent automation systems

The PCAP version offers the familiar smartphone-like touch experience users expect from modern HMI systems while allowing wide-temperature operation for embedded applications.

Wide Temperature Reliability

Industrial applications often expose displays to extreme environmental conditions. Both RFN05000A4 modules are engineered for reliable operation across a wide temperature range of -30°C to +80°C, supporting deployment in outdoor installations, factory automation equipment, transportation systems, and agricultural environments.

This rugged temperature performance allows system designers to standardize their display platform across a broad range of operating conditions without compromising functionality or longevity.
