Patent ID: 7463252

Claim:
A method for displaying an image by activation of pixels of an array screen based on an image stored in digital form in memory point rows of a frame memory, comprising a normal display mode comprising, for the display of a frame, the steps of: (a) providing a succession of row addresses associated with rows of the frame memory; (b) successively reading the states of memory points of the rows associated with the row addresses; and (c) activating, for each row address, pixels of a line associated with said row address based on the read states of the row associated with said address, further comprising a stand-by mode comprising replacing step (c) with the steps of: (d) providing, by a dedicated circuit, at a frequency proportional to the display frequency, a cyclic succession of pixel position offset values comprising a first pixel position offset value; and (e) for each row address, providing a new row address corresponding to said row address offset by the first pixel position offset value and activating pixels of a screen line associated with said new row address, based on the read states of the row associated with said row address, and/or providing new states corresponding to the read states of the memory points of the frame memory row associated with said new row address, said read states being offset by the first pixel position offset value and activating pixels of a screen line associated with said row address based on the new states.
