A method of forming a color display image to be viewed by the visual system of a human viewer, comprising: providing a large format display that includes: a) color pixels each having a first area, with each color pixel comprising a red light emitter, a green light emitter, and a blue light emitter, with each of the R, G, and B light emitters constituting a sub-pixel of the corresponding color pixel; and b) white pixels each having a second area, with each white pixel having at least one white light emitter, wherein the second area is substantially equal to or greater than the first area; sending a digital video signal representative of a color display image to the large format display through a video processor to form a processed digital video signal (SD') defining color information for the sub-pixels of the color pixels and white information for the white pixels, wherein the digital video signal is in a chroma subsampling format comprising a luminance component and chroma components, and wherein the video processor defines the white information for the white pixels by having information of the luminance component go straight to the large format display and without processing the digital video signal SD so that the white information for the white pixels is defined in terms of the color information for the sub pixels of the color pixels; and displaying the color display image on the large format display based on the processed digital video signal. providing a large format display that includes: a) color pixels each having a first area, with each color pixel comprising a red light emitter, a green light emitter, and a blue light emitter, with each of the R, G, and B light emitters constituting a sub-pixel of the corresponding color pixel; and b) white pixels each having a second area, with each white pixel having at least one white light emitter, wherein the second area is substantially equal to or greater than the first area; a) color pixels each having a first area, with each color pixel comprising a red light emitter, a green light emitter, and a blue light emitter, with each of the R, G, and B light emitters constituting a sub-pixel of the corresponding color pixel; and b) white pixels each having a second area, with each white pixel having at least one white light emitter, wherein the second area is substantially equal to or greater than the first area; sending a digital video signal representative of a color display image to the large format display through a video processor to form a processed digital video signal (SD') defining color information for the sub-pixels of the color pixels and white information for the white pixels, wherein the digital video signal is in a chroma subsampling format comprising a luminance component and chroma components, and wherein the video processor defines the white information for the white pixels by having information of the luminance component go straight to the large format display and without processing the digital video signal SD so that the white information for the white pixels is defined in terms of the color information for the sub pixels of the color pixels; and displaying the color display image on the large format display based on the processed digital video signal.
