Image display

Abstract

There is provided an image display including a first light source, a second light source and a modulation unit. The first light source has a plurality of first point lights arranged to form a first shape for generating a predetermined spectrum signal. The second light source has a plurality of second point lights arranged to form a second shape for generating a predetermined spectrum signal. The modulation unit is for simultaneously modulating the first point lights of the first light source with a first predetermined modulation frequency and for simultaneously modulating the second point lights of the second light source with a second predetermined modulation frequency to generate a modulated predetermined spectrum.

What is claimed is : 
     
         1 . An image display, comprising:
 a first light source having a plurality of first point lights arranged to form a first shape for generating a predetermined spectrum signal;   a second light source having a plurality of second point lights arranged to form a second shape for generating a predetermined spectrum signal; and   a modulation unit for simultaneously modulating the first point lights of the first light source with a first predetermined modulation frequency and for simultaneously modulating the second point lights of the second light source with a second predetermined modulation frequency to generate a modulated predetermined spectrum.   
     
     
         2 . The image display as claimed in  claim 1 , wherein the image display is selected from the group consisting of a television, the screen of a game machine, a monitor and a projection screen. 
     
     
         3 . The image display as claimed in  claim 1 , wherein the first and the second predetermined modulation frequencies have a multiple relationship. 
     
     
         4 . The image display as claimed in  claim 1 , wherein the predetermined spectrum signal is an IR signal. 
     
     
         5 . The image display as claimed in  claim 1 , wherein the first shape and the second shape are a line shape and a star shape respectively. 
     
     
         6 . The image display as claimed in  claim 1 , wherein the first shape and the second shape have a same shape but have different areas. 
     
     
         7 . The image display as claimed in  claim 1 , wherein the first light source, the second light source and the modulation unit are integrated on the image display or manufactured as a discrete component coupling to the image display. 
     
     
         8 . The image display as claimed in  claim 1 , wherein the first point lights and the second point lights are IR light emitting diodes. 
     
     
         9 . The image display as claimed in  claim 1 , wherein the modulated predetermined spectrum of the first predetermined modulation frequency and the second predetermined modulation frequency synchronize with each other. 
     
     
         10 . The image display as claimed in  claim 1 , wherein the first light source and the second light source are respectively disposed near different corners of a screen of the image display.
