Display devices and methods for processing light

A method, comprising:

• emitting first light with a first array of light emitters having a first spacing in a first emission region of a display panel;
• emitting second light with a second array of light emitters having a second spacing distinct from the first spacing in a second emission region of the display panel, the second emission region being distinct from and mutually exclusive to the first emission region;
• changing, with a first filter region of an optical filter, distribution of the first light from the first array of light emitters impinging on the first filter region so that the first light has a first distribution after passing through the first filter region;
• and
• changing, with a second filter region, distinct from the first filter region, of the optical filter, distribution of the second light from the second array of light emitters impinging on the second filter region so that the second light has a second distribution distinct from the first distribution after passing through the second filter region.
