• Balanced colors make OLEDs energy-efficient

    OLEDs are green but researchers from Simon Fraser University in British Columbia, Canada believe that there is room for more improvement. They have asserted that based on the colors chosen to make an image, OLEDs can be more energy-efficient. A well-balanced color palette can help to extend the battery life of cell phones and consume 40% less energy. Such a green tweaking is explained well – ‘One is based on a set of discrete user-named (categorical) colors, which are analyzed according to their energy consumption. The second is based on the constrained continuous optimization of color energy in the perceptually uniform CIELAB color space. The researchers quantitatively compare the two approaches with a traditional choice of colors, demonstrating that we typically save approximately 40 percent of the energy. The color sets are applied to examples from the 2D visualization of nominal data and volume rendering of 3D scalar fields.’ Since the pixels in OLED screens are a result of color emitting polymer spots, using the colors that use less energy will help to reduce power consumption. It is calculated that at the same brightness, yellow uses less energy than magenta.


    In the image above you can a map of the US rendered using both normal colors, lower half, and colors that require up to 40 per cent less energy when shown on an OLED display, upper half.
