Abstract:
1. A method for constructing a two-dimensional look up table for modifying an image to be displayed on a display: (a) displaying a two dimensional subpixel pattern on said display with red subpixels having a range of intensities and green subpixels having a range of intensities; (b) sensing said two dimensional subpixel pattern using a sensing device to obtain an XYZ spatial representation; (c) subtracting a dark leakage from the XYZ spatial representation and convert the resulting XYZ spatial representation to RGB values based upon sensed values at a maximum intensity; (d) convert said RGB values to voltage values for said display; (e) determine left crosstalk values based upon subpixels and a respective left adjacent subpixel; (f) determine right crosstalk values based upon subpixels and a respective right adjacent subpixel; (g) determine modified crosstalk values based upon said left crosstalk values and said right crosstalk values; (h) constructing crosstalk voltages based upon said modified crosstalk values.
