         3 . The electronic display of  claim 2 , wherein the comparison comprises a difference between the current color management value and the dynamic input signal value. 
     
     
         4 . The electronic display of  claim 2 , wherein the altered color characteristic of the electronic display comprises chromaticity and luminance of the solid state lighting devices. 
     
     
         5 . The electronic display of  claim 1 , wherein the control system mode alters the chromaticity and luminance of groups of the solid state lighting devices. 
     
     
         6 . The electronic display of  claim 5 , wherein the groups of the solid state lighting devices are altered via pulse width modulation. 
     
     
         7 . The electronic display of  claim 6 , wherein the microcontroller generates the pulse width modulation responsive to the analysis of the color management signals. 
     
     
         8 . The electronic display of  claim 5 , wherein the groups of the solid state lighting devices exhibit differing chromaticity and luminance. 
     
     
         9 . The electronic display of  claim 5 , wherein the groups of the solid state lighting devices comprise tiles of the solid state lighting devices. 
     
     
         10 . The electronic display of  claim 5 , wherein the groups of the solid state lighting devices comprise strings of the solid state lighting devices. 
     
     
         11 . The electronic display of  claim 1 , wherein the LCD panel comprises a two-dimensional arrangement of liquid crystal shutters. 
     
     
         12 . The electronic display of  claim 10 , wherein an LCD controller controls an output image of the electronic display image by varying states of the LCD shutters corresponding to different pixels of the LCD panel. 
     
     
         13 . The electronic display of  claim 1 , wherein the solid state lighting devices are red, blue and green. 
     
     
         14 . The electronic display of  claim 1 , wherein the solid state lighting devices are light emitting diodes.
