A key challenge in outdoor digital signage is ensuring visibility in bright ambient light, especially direct sunlight. Traditional LCDs often fall short in such conditions, relying on power-hungry backlighting to stay visible. Reflective LCD technology, however, harnesses sunlight instead of fighting against it, providing illumination naturally.

How reflective LCD technology works

Unlike conventional LCDs that rely on backlighting to display content, reflective LCDs utilise ambient light, particularly sunlight, to reflect images back to the viewer. This innovative approach produces bright, clear visuals without the need for backlighting, drastically reducing power consumption.

While a traditional LCD display may use around 200 watts to be visible in sunlight, reflective LCDs can achieve superior visibility with less than 5 watts, thus reducing power consumption by up to 40 times. This breakthrough makes reflective LCDs highly efficient and environmentally sustainable for outdoor displays.

Energy efficiency: A key to sustainable signage

Reflective LCD technology is redefining energy efficiency in digital signage, consuming just a fraction of the power required by standard displays. The low power consumption allows businesses to adopt solar-powered systems, significantly reducing both installation and operational costs.

In remote or historical areas where installing electrical infrastructure is challenging, reflective LCDs offer a practical and ecofriendly solution. Their minimal energy requirements make them ideal for locations where wiring is impractical or expensive, advancing sustainability efforts across diverse environments.

Here is a list of some of the advantages offered by reflective LCDs and the kind of use cases they enable:
