Patent ID: 8582208

Claim:
A method of manufacturing a display device, the display device being a security document, the method comprising: providing m images of an object, m being at least equal to 2; dividing each image into sets of adjacent arrays of picture elements, spaced at a mutual distance; applying the images in an interlaced manner on an image layer in sets of interlaced arrays below a lens structure comprising line-shaped lens elements over the image layer with one line-shaped lens element overlying a corresponding set of adjacent arrays by printing or by projection or scanning an optical beam, wherein upon applying the arrays onto the image layer and/or upon providing the lens elements, each array of picture elements is provided onto the image layer in an out-of-focus manner to form a blurred array or each array is imaged by the lens elements to form a blurred array, a mutual distance of edges of adjacent blurred arrays being smaller than the mutual distance by which the adjacent arrays of picture elements are spaced, an increase in width of the arrays caused by applying the arrays in the out-of-focus manner comprising between 5% and 100%.
