(1) The deviation of each output in same color group (OUTR0-15 or OUTG0-15 or OUTB0-15) from the average of same color group constant current. The deviation is calculated by the formula. (X = R or G or B, n = 0-15) GUID-682E8661-E828-41AB-94F5-D831E13928EE-low.gif

(2) The deviation of the average of constant-current in each color group from the ideal constant-current value. (X = R or G or B) :
GUID-86007FE3-078D-4E50-AC8A-94F672EB7339-low.gif Ideal current is calculated by the following equation: GUID-A3F3025E-DE5E-47D7-9000-3E84156D3499-low.gif

(3) Line regulation is calculated by the following equation. (X = R or G or B, n = 0-15):
∆ % V = I X n   a t   V L E D = 5.5   V - I X n   a t   V L E D = 2.5   V I X n   a t   V L E D = 2.5   V × 100 5.5   V - 2.5   V
