Depth-Guided Pixel Dimming with Saliency-Oriented Power-Saving Transformation for Stereoscope AMOLED Displays

With better experience of immersive scene, the virtual reality (VR) becomes the main stream of entertainments. Featuring high chromatic displaying performance, relatively higher efficiency in power and lower latency, the Active-Matrix Organic Lighting-Emitting Diode (AMOLED) is the best-choice display technology for VR. However, AMOLED still requires the higher power consumption amongst other components on smart phones. Thus, various studies attempted to leverage the property of AMOLED to lower the power consumption while preserving the visual quality. This paper proposes a perceptually saliency-oriented transformation by incorporating the concept of how human eyes work in VR environment to provide more suitable experience while saving more power consumption. Experimental results show the proposed method preserves up to 49.33% of the power demand with high perceptual quality as other existing techniques. Furthermore, the subjective experiment demonstrates the proposed method provides a better perceptual quality for VR environment.
