Abstract
Systems and methods that employ a near-eye display system including an optical assembly are described. The optical assembly may include a head-mounted display device worn by a user in which the head-mounted display device adapted to house an image projecting device and an optical assembly. The optical assembly may include, for at least one eyepiece, a first flat filter stack operable to be oriented in a first direction. and a second flat filter stack operable to be oriented in a second direction. The near-eye display system assembly may also include a display panel adapted to receive image content from the image projecting device, wherein the display panel is adapted to be oriented in the second direction.

6. A method of filtering light for a near-eye display system, the method comprising:
-
receiving a light beam at a display panel and from a display that directs light through a first linear polarizer in a first filter stack, the first linear polarizer transmitting the light beam into a first quarter-wave plate in the first filter stack, the light beam becoming circularly polarized in a first direction and being further transmitted through a beam splitter in the first filter stack, the beam splitter operable to transmit at least some of the light beam to a second quarter wave plate in a second filter stack; transmitting a first portion of the light beam from the second quarter wave plate to a polarizing beam splitter in the second filter stack to transform the first portion into a linearly polarized light beam, wherein the polarizing beam splitter is operable to reflect a second portion of the linearly polarized light beam through the second quarter wave plate to the beam splitter, the second portion becoming circularly polarized in a second direction after reflecting off of the beam splitter; and transmitting the second portion from the beam splitter through the second quarter wave plate and through the polarizing beam splitter, through a second linear polarizer in the second filter stack, and through at least one lens to provide a refracted image to an eyepiece of the near-eye display system. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)

14. A system comprising:
-
an interactive head-mounted display device worn by a user, the interactive head-mounted display device adapted to house an image projecting device and an optical assembly, the optical assembly including at least one eyepiece, at least one refracting lens; a first filter stack operable to filter and split light received from the image projecting device, the first filter stack including a first linear polarizer and a beam splitter coating on a first quarter wave plate; a second filter stack including a second quarter wave plate, a polarizing beam splitter, and a second linear polarizer, the second filter stack operable to fold an optical path between the at least one refracting lens and the image projecting device; a display panel adapted to receive image content from the image projecting device; and at least one processor for handling image content for display on the image projecting device. - View Dependent Claims (15, 16, 17, 18, 19, 20)
