“…A number of approximation techniques, targeted primarily at legacy backlit LCDs, have been developed to reduce display power dissipation [16,45]. With the advent of organic light-emitting diode (OLED) displays, a number of research efforts [23,24,30,35,53,61] have explored exploiting approximation of color content to reduce power dissipation in OLED displays.…”

We present Crayon, a library and runtime system that reduces display power dissipation by acceptably approximating displayed images via shape and color transforms. Crayon can be inserted between an application and the display to optimize dynamically generated images before they appear on the screen. It can also be applied offline to optimize stored images before they are retrieved and displayed. Crayon exploits three fundamental properties: the acceptability of small changes in shape and color, the fact that the power dissipation of OLED displays and DLP pico-projectors is different for different colors, and the relatively small energy cost of computation in comparison to display energy usage.We implement and evaluate Crayon in three contexts: a hardware platform with detailed power measurement facilities and an OLED display, an Android tablet, and a set of cross-platform tools. Our results show that Crayon's color transforms can reduce display power dissipation by over 66% while producing images that remain visually acceptable to users. The measured whole-system power reduction is approximately 50%. We quantify the acceptability of Crayon's shape and color transforms with a user study involving over 400 participants and over 21,000 image evaluations.

Abstract-Organic light emitting diode (OLED) display is a self-illuminating device that is supposed to be power efficient than liquid crystal display (LCD). However, OLED display panels consume as much power as LCD panels due to total internal refection. As the power consumption of the OLED panel depends on the pixel colors, most previous power saving methods alter the pixel colors. In practice, such OLED power saving techniques can hardly accommodate photo viewers and movie players. This paper introduces the first OLED power saving technique that dynamically changes the supply voltage of the panel. Reduced supply voltage results in both power saving and decreased pixel luminance, but model-based color correction restores the decreased luminance with minimum color distortion. This technique is similar to dynamic backlight scaling of LCDs but is based on the unique characteristics of the OLED drivers. We provide an online color compensation algorithm using the luminance histogram. Luminance quantization in the histogram also achieves resource minimization. We develop a prototype and demonstrate the proposed OLED dynamic voltage scaling (DVS). Experimental result shows that the proposed OLED DVS saves up to 74.7% of the display power for the still images and up to 35.9% for movie clips.

“…Researchers from HP Labs proposed to selectively darken part of the screen while maintaining good usability for OLED-based mobile displays [3,5,9]. IBM researchers sought to use low-power colors for more pixels and designed GUI objects, such as fonts and icons to minimize the need for high-power colors, on their Linux Wrist Watch [10].…”

“…While many have investigated the power optimization of conventional LCDs, these works do not leverage the extraordinary flexibility provided by OLEDbased displays. A recent few works did leverage such flexibility [3][4][5] but their exploitation was limited to display darkening [3,5] and color inversion [4].…”

Emerging organic light-emitting diode (OLED)-based displays have drastically different power consumption when displaying different colors, due to their emissive nature. They bring a new opportunity for power saving by transforming GUI colors. In this work, we study this opportunity using a commercial-off-the-shelf QVGA OLED module and user studies. We present techniques that adapt GUIs based on existing mechanisms as well as arbitrarily under usability constraints. Our measurement and user studies show that more than 75% display power reduction can be achieved with user acceptance.
