1. A head mounted display (HMD) apparatus comprising:
a display;
an optical lens adjacent to a first side of the display;
at least one light source configured to emit light; and
at least one eye-tracking sensor adjacent to a second side of the display and configured to obtain gaze information about a user by receiving reflected light, the reflected light being at least a portion of the light emitted from the at least one light source and reflected from an eye of the user,
wherein the display comprises a second display region corresponding to a position of the at least one eye-tracking sensor, and a first display region other than the second display region, and
wherein the first display region comprises first pixels and the second display region comprises second pixels,
wherein a spacing between two adjacent pixels of the first pixels is less than a spacing between two adjacent pixels of the second pixels,
wherein the first display region corresponds to a region of interest that has a reference radius corresponding to a reference angle, which is predetermined based on a center of the optical lens, and a distance between the eye of the user and the optical lens, and
wherein the second display region is adjacent to the first display region and is outside the region of interest.
