Abstract
A method for updating a submatrix of a display matrix of a display device comprises sequentially selecting rows of the display matrix starting from an initial row of the display matrix. The method includes determining whether a selected row precedes a first row of the submatrix in a first drive frame of a waveform having two or more drive frames. If a condition that a selected row precedes the first row of the submatrix in the first drive frame of the waveform is false, the method includes addressing the selected row for a first line address period. If a condition that a selected row precedes the first row of the submatrix in the first drive frame of the waveform is true, the method includes addressing the selected row for a second line address period.
