Normal colour displays have 3 differently-coloured sub-pixels (red, green and blue). What happens if we add a yellow one into the mix?


Corrections:

4:05 : It's actually called a "Chromaticity" Diagram, not a "Chromacity" Diagram.

4:39 : As Antsaboy94 pointed out, there technically can be formats that would be more accurately displayed with new subpixels of certain colors, since there exist color space standards (such as Adobe RBG) which support more colours than a conventional display.
