SDA 9380 - B21

Preliminary Data Sheet

System description

White control R, white control G, white control B, CATH[2:0]:

These four control items define the nominal values of the cut-off and white-

drive currents during the measurement lines. They can be calculated with the

following equations:

Icut-off = 0.00325 * (White control x + 64) / RDCI (if RDCI=0)

Icut-off = 0.00108 * (White control x + 64) / RDCI (if RDCI=1)

Iwhite-drive = Icut-off * (CATH[2:0] + 18) / 8

White control x: White control register for R, G or B (range -32...+31)

RDCI:

CATH[2:0]:

Resulting resistor to ground at DCI input

Cathode drive level (range -4...+3) in register RGB control 1
