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