Green Signage: How PPDS Halves Power Consumption

Amsterdam | Last week, PPDS announced the QE-Line, a new generation of displays whose power consumption is 50% lower compared to the previous version and competing devices. With 40-50W average consumption for professional 50-65″ displays, the Philips QE-Line sets new standards. invidis was on site at TPV in Amsterdam.

How to halve the power consumption of digital signage displays? LCD displays are actually considered to be fully developed. Great innovations can no longer be expected; the huge range of displays between 32 and 98 inches is hardly distinguishable for many end customers.

The Taiwanese display manufacturer TPV shows that real leaps in development can still be achieved with its new Philips Ecoline QE series. According to the press release, electricity consumption was reduced by half. A claim that sounds almost too good to be true. We wanted to understand the background and asked Andrea Barbuti, PPDS International Product Manager – Solutions.

And indeed, the power consumption of the new QE line is unusually low and certified by EnergyStar:

  • 50”: 40.5W
  • 55”: 45.3W
  • 65”: 50.7W

Innovative backlight concept with reflective foil

The TPV subsidiary PPDS was able to achieve the greatest progress in energy efficiency through an improved backlight concept with a new reflective film. We don’t want to reveal anything more about it, except that further energy savings can also be achieved using a new power supply and an automatic brightness sensor.

Sustainable even beyond electricity consumption

Display manufacturers have also been optimizing products and packaging beyond electronics for years. PPDS uses recycled resin for the display covers on the back and does not use plastic bags for accessories or Styrofoam packaging.

The entire measures were awarded the EPEAT Silver Climate+ Ecolabel for one of the first digital signage displays. EPEAT measures the social and environmental impact of products from production to the end of their life. The QE line meets 100 percent of the climate criteria and at least 50 percent of the existing optional criteria. Additionally, it has received one of the industry’s lowest energy label ratings for a professional display, with an EU Energy Label E rating for the 50-inch model and a D rating for the 55-inch and 65-inch models.

invidis comment

Halving electricity consumption is an astonishing success in times of energy crisis and green signage. Efficiency improvements – such as those made possible by the new PPDS-Ecoline – show that there is still considerable potential for improvement in LCD displays.

Even if the QE-Line is not a brightness miracle with 300-350 nits, there are still many application scenarios in which digital signage displays are not exposed to direct sunlight and the entry-level brightness level is sufficient.
In the future, end customers will evaluate more frequently whether they prefer more performance (more brightness) or lower power consumption. With power consumption halved to 45 watts for a standard 55-inch model, energy-saving professional LCD displays are now also available.
