Display apparatus configured for display of lower resolution composite color subfields

A method of processing an image frame for display comprising:

• receiving image data indicative of a plurality of pixel values included in the image frame;
• deriving a plurality of initial component color subfields based on the pixel values, wherein each initial component color subfield includes pixel intensity values for a respective component color;
• deriving a composite color subfield including a plurality of common composite color intensity values assigned to respective pixel blocks based on the initial component color subfields, wherein each pixel block is associated with a plurality of pixels;
• and
• deriving a plurality of updated component color subfields based on the initial component color subfields and the composite color subfield.

A non-transitory processor readable medium storing instructions, which, when executed by one or more processors, cause the one or more processors to carry out a method comprising:

• receiving data indicative of a plurality of pixel values included in an image frame;
• deriving a plurality of initial component color subfields, wherein each initial component color subfield includes pixel intensity values for a respective component color;
• deriving a composite color subfield including a plurality of common composite color intensity values assigned to respective pixel blocks based on the initial component color subfields, wherein each pixel block is associated with a plurality of pixels;
• and
• deriving a plurality of updated component color subfields based on the initial component color subfields and the composite color subfield.
