Abstract
A system for reducing crosstalk for a display.
Claims1
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.
