Understanding the Role of Displays in EV Chargers

Apart from the whole functionality of the Electric Vehicle chargers, the display can be the toughest choice, that will influence the whole user experience. This is because it serves as the primary interface between the user and the charging system. Whether it’s showing charging status, guiding payment processes, or displaying advertisements, a well-chosen display significantly enhances usability and satisfaction.

Nowadays there are many companies focused on delivering the best possible electric vehicle charging solutions to the market, but only the best ones will survive. The display is one of those crucial components that can differentiate a product in a competitive market.

Evaluating Display Size for EV Chargers

For the EV chargers the most popular sizes are 7″, 10.1″ and 15″, but some of the producers are picking even 32.1″ displays that cover almost the whole front of the machine. The choice should reflect both design constraints and user accessibility. Smaller than 7” may hinder readability for older users or those with visual impairments. Larger screens (above 15”) not only improve visibility but also lend a modern and premium feel to your charger.

At Kadi Display, options like 10.1inch IPS 1920×1200 TFT LCD with LVDS Interface or 12.3” TFT-LCD Module With High Brightness offer excellent balance between size and performance for various applications.

Brightness Requirements for Outdoor and Indoor Use for Displays in EV Chargers

Brightness directly affects readability under various lighting conditions. The choice depends on the location of the application, and the insolation there. For indoor environments such as underground parking lots, brightness levels around 300-500cd/m² are generally sufficient.

However, for chargers that are going to stand outside, the brightness should be at least in a range of 1000cd/m², but even 2000cd/m² could be recommended. Kadi Display offers high-brightness modules like 12.1” TFT-LCD Module High Brightness LVDS, which can reach up to 1000nits or more, ensuring visibility even under direct sunlight.

Importance of Viewing Angles in Public Installations of Displays in EV Chargers

Public EV charging stations are accessed from multiple angles by users of varying heights and positions. Therefore, wide viewing angles are essential. IPS matrix technology has not only most of VA’s advantages but also very good color reproduction and highest viewing angles in both axes.

Kadi Display’s IPS displays such as The IPS TFT LCD has a viewing angle of up to 178 degrees, ensure consistent image quality regardless of where you’re standing.

Choosing the Right Input Method: Buttons, Touch, or Touchless for Displays in EV Chargers

Input methods must align with user expectations and environmental conditions. Both, buttons and touch solutions are very popular, but the whole world is currently switching to capacitive touch technology. Capacitive touchscreens are intuitive and similar to smartphones—making them familiar to most users.

Kadi Display supports various touch technologies including capacitive (CTP), resistive (RTP), and even supports optical bonding for enhanced durability and responsiveness. For example: 10.1 inch 1280×800 industrial grade TFT LCD display with CTP provides excellent touch response suitable for public use.

In pandemic-conscious environments or high-traffic areas, touchless options using sensors may provide an added layer of hygiene.

Assessing Front Glass Thickness and Durability for Displays in EV Chargers

Public installations demand high resistance against vandalism or accidental damage. From our experience for sizes 7″- 10.1″ it’s recommended to use thermally tempered or chemically strengthen glass at least 4-6 mm thick.

While PMMA may seem cost-effective initially, it scratches easily—leading to poor aesthetics over time. Tempered glass is way more durable, making it ideal for long-term deployment in public spaces.

Kadi Display offers customization services where you can specify Cover Glass as your request: LOGO/Color/Shape/Thickness.

Optical Bonding vs. Air Bonding in Display Assembly for Displays in EV Chargers

Bonding impacts both visual clarity and durability:

• Air bonding is a method of gluing the touch to the display by using adhesive tape on the edges. It’s cost-effective but results in light reflection due to air gaps.

• Optical bonding is a process of putting the touch panel to the display by using liquid adhesive glue. It enhances contrast by eliminating air gaps and improves resistance against dust and moisture intrusion.

Kadi Display’s optically bonded displays like 10.1″ 1280×800 TFT LCD Display With Optical Bonding &anti-glare offer better performance under outdoor conditions while maintaining sleek aesthetics when powered off.

Interface Compatibility with Charging Station Systems for Displays in EV Chargers

Interface selection determines how easily your display integrates with existing systems:

For the EV chargers we mostly see LVDS as the most popular interface for sizes 7″-15″. It supports high-speed communication over inexpensive cables while being resistant to noise interference.

Kadi Display’s catalog includes multiple interface options such as:

• LVDS: e.g., 10.1inch IPS LCD Display with LVDS Interface

• MIPI: e.g., 7.5 inch 800 X 800 Square TFT-LCD MIPl Interface TFT-LCD

• HDMI & USB Type-C: available upon customization request
