摘要： A scan driving method for LCD panel comprises varying of polarity pattern adaptive to column data, wherein polarity patterns are dynamically determined from row to row, based on analysis of column drive signals for present and previous rows to obtain a parametric value and determination to either keep default polarity pattern or switch to alternate polarity pattern in accordance with parametric value obtained. Columns are regarded as in one or multiple groups for consideration. A total drive differential value is used as parameter, switching from default polarity pattern to alternate polarity pattern when a threshold is exceeded, to reduce total drive differential going from row to row. Column inversion is a default and dot inversion is an alternate.

摘要： An LCD Driver System (10) includes a row decoder (38) for providing command signals to row drivers (50) and a RAM row decoder (64) for controlling a RAM (76) which supplies data to a column driver (88). The row and column drivers (50 and 88) are supplied with power by a power source (58) which can supply either high or low voltages. In normal mode, the power source (58) supplies high voltage and the row driver (50) drives both a dot matrix portion (14) and an icon portion (16) of an LCD display. In an icon mode, a disable signal disables the row decoder (38) and the RAM row decoder (64), enables only the icon row driver (54) of the row drivers (50) and the icon row of the RAM (76) and switches the power source (58) to supply low voltage so as to save power.
