You need either an instrument to measure the XYZ values of the displayed chart (a colorimeter or spectroradiometer) or a characterization of the display that will allow you to convert the displayed RGB values to XYZ. You can then compute CIELAB values for both the original chart and the LCD display and from their calculate color differences using any of the recent CIE color difference equations. You might look in Berns’ “Principles of Color Technology, 3rd Ed.” for details on each of these steps.
