摘要： According to the present invention, a display driver includes a voltage and current source that drive pixels and compensate for parasitic voltage to produce row pixels having intensities that are relatively uncorrelated to the number of “ON” pixels in a given row. The voltage source that provides the pre-charge for each pixel includes a constant value and a compensation voltage determined based on the number of “ON” pixels in each row. The compensation voltage is also determined based on the characteristics of the diodes associated with each pixel and the resistance associated the common ground of each row.

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.
