Not so ordinary display

Relec explains how a manufacturer of EV charging stations is benefitting from a novel display design which marries ease of use with durability and energy efficiency.

Escalating EV demand has driven a corresponding and substantial need for efficient, user-friendly EV charging stations. One critical component is the charging station’s display unit, which provides information likecharging status, billing details and instructions.

In this case study, Relec analyses the application of a specific 4in 1×1 aspect ratio IPS TFT LCD display in EV charging stations, outlining its key features and benefits. The display is designed with a suite of distinctive features making it a perfect choice for EV charging stations.

Offering a wide operating temperature, the display operates effectively between -20 and 70°C, making it suitable for charging stations in a variety of climates. With a brightness of 1,000cd/m2 and a contrast ratio up to 800, the display is perfect for daytime use. Users can read the information easily, even in bright sunlight.

A near 180deg viewing angles enhances the display’s readability from different viewpoints, providing ease of use. Optical bonding reduces glare and enhances daylight readability, letting the display offer high visibility under various lighting conditions.

The custom cover glass protects the display and offers a sleek look, while the unique square design enables a compact form factor without compromising information display. Despite its high- performance characteristics, the display uses energy efficiently, aligning with EV’s sustainability focus.

Depending on specific requirements, customers can opt for mounting frames, antibacterial films and custom cabling. A globally recognised EV charging infrastructure provider recently decided to upgrade its display units to enhance customer experience and operational efficiency. After a thorough market study, they chose this display for its charging stations.

The wide operating temperature range offered by the LCD display allowed installation of the charging stations in various regions with extreme weather conditions, from hot deserts to icy tundras, without worrying about the display’s performance. The high brightness and contrast ratio, along with the near 180-degree viewing angles, enhanced the customer’s readability, even under harsh sunlight.

The optical bonding technique made the display more robust, helping it withstand day-to-day wear and tear while enhancing visibility. The unique
1:1 square design and custom cover glass made the stations aesthetically pleasing, attracting more customers. The low power consumption aligned with the company’s sustainability goals, providing a high-performance solution with minimal environmental impact.

The additional options like antibacterial films and custom cabling provided extra layers of safety and ease-of-use, significantly enhancing the overall
user experience. Since installing the displays, customer satisfaction has notably increased. Users find the displays easy to read and interact with, especially in daylight, improving the charging experience. Additionally, the display’s low power consumption has reduced energy costs at the stations. Durability from the custom cover glass and optical bonding also means less maintenance and lower operating expenses.
