By the end of this guide, you’ll be ready to specify a custom EV charger LCD that delights users and supports your business growth.
Display Size
The size of an EV charger display plays a key role in how easily drivers can read information while charging. A larger screen can show clear instructions, charging status, and even helpful graphics without crowding the layout. On the other hand, an oversized display might make the charger look bulky and increase costs.
When choosing a screen size, consider the distance between the driver and the charger. If the unit will be mounted at eye level, a medium-sized EV charger LCD—around 7 to 10 inches—often strikes the right balance. This size is large enough to present clear text and simple icons, yet remains compact enough for sleek charger designs.
For unique installations or branding needs, a custom EV charger display allows you to tailor the dimensions precisely. Custom panels can fit into tight enclosures or span wider housings, ensuring your charging station looks polished and professional. By partnering with a specialized manufacturer, you can choose exactly the screen size that meets your space, style, and budget requirements.
Brightness and Visibility
A bright EV charger display ensures drivers can read information clearly, even in direct sunlight. When screens lack sufficient brightness, important details like charging status or prompts can become washed out. This leads to confusion and can slow down the charging process.
Look for displays rated at least 800 to 1,000 nits if your chargers will be outdoors. These higher nit levels help maintain legibility under bright daylight. Indoor chargers can often use lower brightness—around 400 to 600 nits—while still providing clear text and graphics.
Anti-glare coatings and matte finishes also improve visibility. Glare from the sun or overhead lights can create distracting reflections. A well-treated screen surface diffuses these reflections, making the display easier to read at a glance.
Adaptive brightness technology further enhances usability. By automatically adjusting the screen’s backlight based on ambient conditions, adaptive displays conserve energy when full brightness isn’t needed. They also prevent the display from appearing too dim in low-light situations.
Viewing Angles
Viewing angles determine how well the EV charger LCD can be seen from different positions. If a driver approaches the charger from an angle, a narrow viewing range can make the screen look dim or distorted. This risks misreading important information.
To avoid this, choose displays with wide viewing angles—typically 170 degrees horizontally and vertically. Such screens ensure text and graphics stay clear, whether you’re standing directly in front or slightly to the side. This flexibility enhances user comfort and reduces mistakes.
In busy charging stations, where multiple users may walk by, wide viewing angles also improve overall accessibility. Everyone can quickly see the screen without shifting their position, making the charging experience smooth and intuitive.
Input Methods
How users interact with the display affects both convenience and reliability. Many EV chargers use touchscreens that allow drivers to tap buttons or swipe through menus. A responsive capacitive touch panel feels familiar, like a smartphone, and works well with light taps.
However, touchscreens may struggle when users wear gloves or when the screen surface is wet. In these cases, resistive touch panels can be more reliable. They respond to pressure rather than electrical conductivity, ensuring the charger remains functional in cold weather or rainy conditions.
Physical buttons offer another option. While they add mechanical parts that can wear out over time, tactile feedback gives users confidence that their input registered. Combining a small set of buttons with a touchscreen can provide both precision and versatility in various environments.
For custom solutions, discuss the input method with your display partner. They can integrate specialized sensors, such as proximity detectors or infrared touch frames, to match your charger’s unique use cases. This tailored approach ensures drivers enjoy a smooth, frustration-free experience every time they plug in.
Durability
An EV charger display must withstand harsh conditions day after day. Outdoor chargers face extreme temperatures, rain, snow, and even direct sunlight. If the screen isn’t rugged enough, it can crack, fade, or stop working altogether.
Look for displays rated with high ingress protection (IP65 or above). This rating means the screen is sealed against dust and water jets. Tempered glass adds another layer of protection against impacts and scratches. Together, these features help your charger stay reliable through years of use.
Humidity and salt spray—common near coastal areas—can also harm electronic components. Choosing corrosion-resistant materials and seals prevents moisture from creeping inside. A durable display saves on maintenance costs and keeps your charging station online, even in challenging environments.
Bond Technology
Bond technology refers to how the display panel is attached to the touch sensor and protective glass. Optical bonding fills the air gap between layers with a clear adhesive. This process reduces internal reflections, improving contrast and clarity. Drivers will see sharper text and richer colors, even in bright light.
Displays without proper bonding can suffer from “fogging,” where moisture or dust enters the air gap. This lowers visibility and may require costly repairs. By choosing optically bonded custom EV charger LCD panels, you ensure long-term performance and a premium look.
Manufacturers may offer different bonding options, such as full-surface bonding or edge bonding. Full-surface bonding provides the best optical performance, while edge bonding can be more cost-effective. Discuss your priorities—clarity, budget, or both—with your display supplier to find the right fit.
Interfaces and Connections
A good EV charger display must communicate seamlessly with the charger’s control system. Common interfaces include HDMI, LVDS, and eDP for video signals. Each protocol has different bandwidth and cable requirements.
For simple applications, HDMI offers plug-and-play convenience. If you need higher data rates for detailed graphics or animations, consider eDP. LVDS is popular in industrial settings for long cable runs and reliable performance under electrical noise.
Touch input often uses USB or I²C connections. Using standardized interfaces simplifies integration and troubleshooting. Custom EV charger displays can be preconfigured with the interfaces you need, reducing development time and ensuring compatibility with your existing hardware.
Power Consumption
Energy efficiency matters not only for the environment but also for charger operating costs. Bright, high-performance screens can draw significant power. When selecting a display, check the manufacturer’s power specifications at different brightness levels.
Some EV charger LCD panels include power-saving modes. These can dim the backlight or enter standby when not in use. Adaptive brightness, as mentioned earlier, also contributes to lower energy use. By optimizing both hardware and firmware, you can minimize the display’s power draw without sacrificing visibility.
Choosing low-power displays helps your charging stations meet energy regulations and reduces the overall cost of ownership. It’s a smart move for sustainability and your bottom line.
