1. A display screen for displaying a multiple-resolution image and comprising a plurality of pixels distributed on a support, wherein the display comprises a first zone of a face of the support having a first density of pixels, enabling display of a first part of the image at a first resolution, and a second zone of the face of the support having a second density of pixels, strictly greater than said first density, enabling to display a second part of the image at a second resolution, and at least another zone separating at least partially the first and second zones, and having a density of pixels comprised between the first density of pixels and the second density of pixels, the said at least one other zone enabling to display at least one other part of the image with an intermediate resolution comprised between the first and second resolutions, wherein the first and second densities of pixels and the density of pixels of the at least one other zone are selected so as to display a multiple-resolution image having a variation of resolution between the first and second parts of the image and the at least one other part of the image that is similar to a sensitivity profile of a retina of a human eye.
