Dot Correction (DC) Data

DC data are 112 bits long; the data for each constant-current output are controlled by seven bits. Each constant-

current output DC is controlled by the second control data latch. Each DC value individually adjusts the output

current for each constant-current output. As explained in the Dot Correction (DC) Function section, the DC

values are used to adjust the output current from 0% to 100% of the maximum value.

The DC data bit assignment in the first and second latches are shown in Table 8. Refer to Table 2 for a summary

of the DC data value versus set current value.

Global Brightness Control (BC) Data

Global BC data are seven bits long. The global brightness for all outputs is controlled by the second control data

latch. The data are used to adjust the constant-current values for the 16 constant-current outputs. As explained

in the Global Brightness Control (BC) Function section, the BC values are used to adjust the output current from

25% to 100% of the maximum value. The global BC data bit assignment in the first and second latches is shown

in Table 9. Table 3 summarizes the BC data value versus set current value.
