Display apparatus

A display apparatus comprising:

• a light emitting unit which emits light;
• a light scanning unit which includes at least one light reflector reflecting light emitted from the light emitting unit and being swingably installed around a swing axis, scans the light reflected by the light reflector on a display surface where an image is to be displayed in a first direction, and scans in a second direction perpendicular to the first direction at a speed lower than a scanning speed of the first direction;
• an amplitude changing unit which changes an amplitude of the swing of the light reflector;
• and
• a light emitting control unit which adjusts a light emitting timing of the light emitting unit and an amount of light emitted from the light emitting unit,
• wherein the amplitude changing unit changes the amplitude of the swing of the light reflector, so that a first state where the light is scanned in a first region of the display surface and a second state where the light is scanned on the first region and a second region different from the first region of the display surface are switched over each other, and
• wherein the light emitting control unit allows an amount of light per unit area of the first region in the first state and an amount of light per unit area of the first region in the second state to be equalized by adjusting the amount of light emitted from the light emitting unit.
