CA 2558774

The present invention relates to an image display apparatus provided with a display section of LEDs which are the pixel elements, a correction data memory section and control and driver circuitry. The display section of LEDs are arranged in an m-line by n-column matrix. The correction data memory section stores correction data corresponding to the LED for each respective pixel. The correction data memory section is provided with a first memory bank which forbids writing to memory and holds pre-stored first correction data, and a second memory bank which allows writing to memory. The control and driver circuitry corrects input image data based on the correction data and displays an image on the display section using the corrected image data.
