Abstract:
A display screen comprising:addressing rows and columns defining, at their overlaps, a matrix of pixels, these pixels corresponding to first subassemblies referred to as intermediate subassemblies, these intermediate subassemblies having repetitive transparent areas produced in the rows and/or columns;second subassemblies, referred to as anode subassemblies, each comprising a luminescent part, at least one anode subassembly being disposed opposite an intermediate subassembly and being able to be observed by transparency through the intermediate subassemblies;this screen being characterised by the fact that each intermediate subassembly comprises elementary patterns which are repeated according to a first pitch along a first direction and according to a second pitch along a second direction, the second pitch being less than the first and being equal to a fraction of the dimension of an anode subassembly along this second direction.
