Abstract
A field emission image display is provided that can obtain a suitable white balance even when the luminous brightness of fluorescent substances is different. When an image is displayed on a field emission display (FED) panel based on input image data, correction data for correcting image data for each color is previously stored into the look-up table,to set properly the white balance in each gray scale of a display image to be displayed on the FED panel. The white balance of a display image to be displayed on the FED panel is nearly maintained to a constant value by correcting image data to be input using the correction data stored in the look-up table
