摘要
A head mounted display system includes a display device and an eyetracking device. The display device includes a liquid crystal (LC) panel comprising a plurality of rows of pixels, a back light unit (BLU), and a data driver. The BLU emits light during an illumination period of a frame period from an illumination start time and does not emit light for a remaining portion of the frame period. The eyetracking device determines an eye gaze area of a user in a pixel area of the display device. The illumination start time varies based on a location of the eye gaze area of the user. Liquid crystal material in a row of pixels of the LC panel outside the eye gaze area of the user transitions during the illumination period.
