Patent ID: 8344996

Claim:
A method for updating a submatrix of a display matrix of a display device, comprising: in a writing waveform comprised of multiple drive frames wherein all the rows of all the drive frames between the first and last drive frames are addressed, sequentially selecting rows of the display matrix starting from an initial row of the display matrix; determining whether a selected row precedes the first row of the submatrix in the first drive frame of said writing waveform; if a condition that a selected row precedes the first row of the submatrix in the first drive frame of the writing waveform is false, then 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 writing waveform is true, then addressing the selected row for a second line address period different from said first line address period; determining whether the selected row follows the final row of the submatrix in the final drive frame of the writing waveform; if a condition that a selected row follows the final row of the submatrix in the final drive frame of the writing waveform is false, then addressing the selected row for said first line address period; and if a condition that a selected row follows the final row of the submatrix in the final drive frame of the writing waveform is true, then addressing a selected row for said second line address period.
