Claim Text:
1. A display apparatus comprising: a display panel configured to display a first image during a first subframe and a second image during a second subframe; a light source part configured to provide backlighting light to the display panel; and a directional light projecting element disposed between the display panel and the light source part, and including a barrier part and a lens part, the lens part being disposed above the barrier part; wherein the barrier part has a plurality of selectively activateable barriers defined by a corresponding plurality of elongated first electrodes extending in a first direction and a plurality of elongated second electrodes extending in a second direction different from the first direction and thus crossing with the elongated first electrodes; and wherein the lens part has a plurality of lenses disposed in accordance with an area tessellating pattern, each of the lenses having a coverage area corresponding to a respective subplurality of the barriers, and wherein a vertical pitch of the first electrode is equal to a horizontal pitch of the second electrode, and the vertical pitch of the elongated first electrodes is defined as a center-to-center distance between the adjacent elongated first electrodes, and the horizontal pitch of the elongated second electrodes is defined as a center-to-center distance between the adjacent elongated second electrodes, and wherein the barriers have a matrix configuration defined by crossing of the elongated first electrodes and the elongated second electrodes.
