Abstract (en)
[origin: WO2008142301A1] The invention relates to a method of addressing a nematic bistable liquid crystal matrix screen having two stable states without electrical field applied. The switching of each pixel from one stable state to another stable state is controlled by a switching electrical voltage pulse obtained by the application of at least one row addressing signal applied to a row addressing electrode (L1 to LN) and the application of at least one column addressing signal applied to a column addressing electrode (C1 to CM). According to the invention, the characteristics of the row addressing signals and/or the characteristics of the column addressing signals are a function of the position of said pixel in said matrix screen. Application: liquid crystal display screen.
