Green Display Marketing: Sustainable Practices for Screens and Displays

On LED screens, power use depends largely on how bright and how light-coloured the displayed image is. Content design can therefore make a difference:

• Avoid large bright white areas where a darker background works just as well for readability.
• Use only the brightness you need: Content designed with strong contrast stays readable at lower brightness settings.
• Keep content purposeful: Clear, simple designs often communicate better and need less brightness to stand out.

The actual saving depends on the screen, content and settings, so measure consumption where possible rather than relying on general figures.

For printed and physical displays, material choice matters:

• Recyclable or recycled materials: Such as recycled board, recycled acrylic or metals that can be reused.
• Reusable structures: Frames and stands designed for many campaigns, with only the graphics changed.
• Newer bio-based materials: Some bio-based boards and plastics are emerging; check their durability and how they can actually be disposed of locally.

Claims such as “compostable” or “carbon-neutral” should be supported by the supplier’s documentation and local disposal options.

A longer product life is one of the most effective sustainability measures:

• Choose repairable, modular hardware with available spare parts, so faulty modules can be replaced instead of the whole screen.
• Maintain equipment to extend its life.
• Redeploy screens to new locations or uses instead of discarding them.
• Recycle responsibly at end of life through proper e-waste channels.
• Reuse creative assets: Update and adapt existing visuals and videos for new campaigns instead of always starting from scratch.

One of the simplest green choices happens before purchase: buying a screen that fits the job rather than one that is larger, finer or brighter than needed. An over-specified screen uses more material to make and often more electricity to run.

• Pixel pitch: a practical rule of thumb is that the minimum comfortable viewing distance in metres is roughly equal to the pixel pitch in millimetres. A finer pitch than viewers can appreciate adds components without adding visible benefit. Our pixel pitch guide explains how to choose.
• Brightness: indoor screens typically need around 600 to 1,000 nits, while outdoor screens usually need around 4,500 to 6,500 nits for direct sun. Running an indoor screen near outdoor brightness levels wastes energy and can cause glare.
• Size: size the screen to the space and audience. A well-placed smaller screen can communicate as well as a larger one in the wrong spot.

In Pakistan, the biggest threats to a screen’s working life are heat, dust, monsoon moisture and unstable power. Protecting against them is also a sustainability measure, because a screen that lasts longer delays manufacturing and e-waste.

• Heat and ventilation: keep airflow clear around the cabinets. Running cooler is generally easier on LEDs and power supplies.
• Weather protection: outdoor screens should have at least an IP65 front rating, with seals and cable entries checked before and after the monsoon.
• Power quality: proper earthing, surge protection and a planned shutdown and restart routine for load-shedding help protect electronics from damage.
• Front-service design and spares: screens whose modules can be swapped from the front, with spares from the same batch, are easier to repair than replace.
• Smart control: controllers such as NovaStar systems can handle light-sensor dimming and schedules automatically, so savings do not depend on someone remembering to switch off.

If you plan to run a screen partly on solar, size the system using the maximum power figure from the datasheet and have a qualified electrician design the connection.

• Is the pitch, size and brightness right for the site, not more?
• Does the datasheet list average and maximum power?
• Is automatic dimming and scheduling set up from day one?
• Are ventilation, weather protection and electrical protection in place?
• Are spare modules and power supplies available for repair?
• Is there a plan to redeploy or recycle the screen at the end of its use?

Our services include help with configuration and maintenance, so efficiency settings and repairs are handled properly over the screen’s life.
