Only one combination is allowed to turn the color tone correction on or off in 1 HSYNC cycle. In other words,
when multiple combinations of correction is required, repeated color tone correction with required number of
gray scale display at one time is necessary. The following is example when all combinations for color tone
correction are needed. Since the current value of the constant-current output for basic display is determined
by the brightness adjustment data plus the dot correction data, the current value for color tone correction is
determined per pixel by the color tone correction data packet based on the current value excluding the dot
correction data after brightness adjustment, although it is different by the constant-current output depending
on dot correction data. Accordingly, the current value for color tone correction is shown as follows.
OUT0 (ROUT0) = OUT1 (GOUT0) = OUT2 (BOUT0), OUT3 (ROUT1) = OUT4 (GOUT1) = OUT5 (BOUT1)
OUT6 (ROUT2) = OUT7 (GOUT2) = OUT8 (BOUT2), OUT9 (ROUT3) = OUT10 (GOUT3) = OUT11 (BOUT3)
