Scale Measurement Technique of LED Display Panel

The technology on scale control is becoming more maturing in LED display which has been mostly digitization these days.The original method of luminance and scale test has become an obsolete stock and the new measurement means must be developed.The paper analyzed the relation function between image data and grayscale which can indicated and gives the method for the scale measurement technic in LED display.Experimental result indicates that the method which obtained the relation function from the scale control level based on the statistics of incremental rate of gray difference can achieve the desired effect.
