摘要： A display apparatus for presenting three-dimensional imagery, including an optical combiner having a first side, a second side, a third side and a fourth side. The second side is opposite to the first side and the fourth side being is opposite to the third side. Optical combiner further includes a first semi-transparent reflective portion arranged to reflect light incoming from the first side towards the fourth side and a second semi-transparent reflective portion arranged to reflect light incoming from the second side towards the fourth side. Light incoming from the third side passes through the first semi-transparent reflective portion and the second semi-transparent reflective portion towards the fourth side. The display apparatus further includes of a first display, a second display and a third display arranged at a first distance, a second distance and a third distance from the first side, the second side and the third side of the optical combiner, respectively, wherein a first image, a second image and a third image rendered at the first display, the second display and the third display are presented at a first focal distance, a second focal distance and a third focal distance, respectively, thereby creating the three-dimensional image.
