Consider now color display mode and two pixels p0 and p1 with the horizontal coordinates 4*n+0, and 4*n+1. A
color pixel is composed of three components: {R, G, B}. Pixel p0 will be displayed sending the color components
{R0, G0, B0} to the display. Pixel p1 will be displayed sending the color components {R1, G1, B1}. Suppose that
the data read from memory and mapped to the lookup tables corresponds to shade level 10 for the three color
components of both pixels, with the dithering pattern to apply to all of them being DP2_3 = “1101 1011 0110”.

figuration, each panel data bus acts like in the equivalent single scan configuration.)
Note:
Ri = red pixel component ON. Gi = green pixel component ON. Bi = blue pixel component ON. ri = red pixel component OFF.
gi = green pixel component OFF. bi = blue pixel component OFF.
gi = green pixel component OFF. bi = blue pixel component OFF.
