Abstract:
1. A color calibrator of a display device, the color calibrator comprising: a color estimator, receiving digital counts of a first initial color, a second initial color and a third initial color of an image signal, the color estimator comprising: an electrical driving signal generator, receiving the digital counts of the first initial color, the second initial color and the third initial color of the image signal, the electrical driving signal generator comprising: an electrical-optical inverse converter, receiving the target gray value digital count, the target mixed color digital count and the target initial color digital count and performing an inverse conversion on the target gray value digital count, the target mixed color digital count and the target initial color digital count to generate an applied gray value digital count, an applied mixed color digital count and an applied initial color digital count, wherein the inverse conversion is an inversion operation of a signal conversion and operation performed by the gray value electrical-optical converter, the mixed color electrical-optical converter, the initial color electrical-optical converter, the plurality of linear transformers and the weighting operator.
