prior to the determining of the position error, turning on all the light sources to allow the light from the light sources to pass through corresponding display sections;
measuring brightness of each of the display sections;
comparing the brightness of each of the display sections to a predefined value;
specifying high brightness display sections having the brightness higher than the predefined value and low brightness display sections having the brightness lower than the predefined value, based on results of the comparing; and
among the light exit sections, decreasing amounts of light that is emitted by the light sources corresponding to the light exit sections that are disposed opposite to the high brightness display sections and increasing amounts of light that is emitted by the light sources corresponding to the light exit sections that are disposed opposite the low brightness display sections so as to uniformize brightness of the display area.
