A display presents information as visual images with plural pixels, each pixel having red, green and blue OLED films that illuminate with varying intensity defined by pixel values generated by a graphics processor. An image adjuster alters the pixel values for pixels located outside the field of view of an end user so that degradation of OLED material occurs in a balanced manner, such as by reducing illumination of blue OLED material, which tends to degrade at a more rapid rate than red and green OLED material.
