Abstract
A head mounted display (HMD) includes first display pixels, second display pixels, and third display pixels. The second display pixels are disposed between the first display pixels and the third display pixels. The first display pixels and the second display pixels are within a first field of view (FOV) of a first eye of a user of the HMD and the second display pixels and the third display pixels are within a second FOV of a second eye of the user. A selectable optical element is driven to a first state and a second state to make the second display light from the second display pixels visible to the first eye during a first time period and visible to the second eye during a second time period to expand the FOV for the user.
