Fast and lightweight writing or reading of pixels of a 2d shape in an active matrix digital display

An active matrix digital display comprising:

• a plurality of pixels, each pixel comprising a static memory storing one or more values of intensity of the pixel;
• an interface configured, upon the reception of at least one command to:
• obtain an identifier of a type of the command;
• if the type of the command of the command belongs to at least one type relative to a 2D shape:
• reading, in a predefined position of a payload of the command, at least one parameter comprising at least one parameter relative to at least one pixel position in the display screen and at least one parameter relative to at least one dimension of the 2D shape, the size of the payload being dependent upon said at least one dimension of the 2D shape, and a pixel path associated to said 2D shape being parameter according to said at least one dimension of the 2D shape;
• one or more of:
• writing to the static memories of a subset of pixels of the screen from the payload of the command values of intensities of said subset of pixels based at least on said at least one parameter relative to at least one pixel position, and according to said pixel path, and
• reading from said static memories of the subset of pixels values of intensities of said subset of pixels based at least on said at least one parameter relative to at least one pixel position, and according to said pixel path.
