Power dissipation has been an inevitable problem of LCD systems for years. To ease the problem, many encoding methods have been developed, such as the methods of transition minimized differential signaling, the most popular one in use for DVI to date, chromatic encoding, and limited intraword transition. In this paper, the authors present the absolute difference and low-power encoding method for the serial transmission of LCD digital DVI display interface. In regard to the LCD digital display interface with UMC 90 nm technology, the proposed method minimizes the architectural complexity and reduces the power dissipation by about 67% and 12%, respectively, compared with the transition minimized differential signaling and limited intraword transition. In short, the proposed method is an efficient bus encoding method to largely decrease the dynamic and total power dissipation of the LCD digital display interfaces.
