2-2 CCA Adjustment Service Methods
CCA Adjustment is needed after changing a light engine or digital board
2-2-1 CCA
In DLP TV, even the same RGB color may differ depending on the light engine. CCA (Color Coordinate Adjustment) corrects the
color to achieve the color accuracy. CCA performs color correction after measuring and inputting the current light engine's data on
actual color coordinates for displayed Red, Green, Blue, and White color patterns, using a color coordinate measuring equipment.
At this moment, color correction is performed on the basis of previously inputted Desired Color Coordinates and Measured Color
Coordinates. Measured Data on Service Engine's color coordinates is presented on the CCA label. Input the label values to per-
form CCA color correction.
