Abstract
This works presents a low-power encoding techniques suitable for digital interface of Liquid Crystal Displays (LCD), an in particular for a standard interface called Gigabyte Video Interface (GVIF), which is employed in many laptop computers.
The encoding is based on the spatial correlation that exists between consecutive pixels and, exploiting the serial nature of the transmission protocol, it encodes pixel differences with limited intra-word transition codewords so that to minimize the transition activity over serial links.
Application of this idea to GVIF-encoded data shows average transition savings of about 50% with respect to plain GVIF data, with the addition of relatively simple encoding architecture.
