3-4-3 CCA Adjustment Service Methods
: CCA Adjustment is needed after changing a light engine, digital board or Color Wheel.
■ 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 color
coordinate measuring equipment.
At this moment, color correction is performed on the basis of previously inputted Desired Color Coordinates and
Measured Color Coordinates.
