  • Abstract

    This paper presents a low-power bus encoding technique suitable for the digital interface to a Liquid Crystal Display (LCD). In particular, we focus on interfaces that are compliant to the Digital Visual Interface (DVI) standard, in which the three color channels are serially transmitted to achieve high bandwidth.The proposed technique exploits the well-know inter-pixel correlation that exists in typical images by serially transmitting an encoded representation of the difference between adjacent pixels. The encoding is based on the principle of clustering the 1's in the code towards either ends of the pixel data, in such a way that serial transmission of a code yields at most 1 transition per pixel.The application of the encoding to a series of standard images resulted in energy savings of around 60% on average, with respect to a plain transmission of 8-bit pixel data.
