Abstract
A display apparatus comprises a mirror assembly, a first mirror of the mirror assembly oscillating about a first axis upon excitation by a first excitation signal and the first or a second mirror of the mirror assembly oscillating about a second axis upon excitation by a second excitation signal, a light source projecting a light beam onto the mirror assembly for deflection by the mirror assembly towards an image area, the light source being controlled according to pixels of image frames, a gaze tracker detecting a user's region of interest, ROI, within the image area, and a controller modulating one of the excitation signals by a first modulation signal which is dependent on the ROI detected by the gaze tracker.
