Abstract
A head-mounted display system including a high resolution active matrix display which reduces center of gravity offset in a compact design. The active matrix display can be either a liquid crystal display or a light emitting display.
Claims21
A method of displaying images with a head mounted display system comprising:
- providing a support frame that is mounted on a user's head;
- providing a transmissive active matrix display and a light source coupled to the display along a single optical axis and mounted on the support frame, the display comprising an array of pixel circuits formed with a silicon material, an array of pixel electrodes formed with a silicon material and connected to a pixel circuit, a row driver circuit and a column driver circuit formed with the silicon material and electrically connected to each pixel circuit such that actuation of a pixel circuit transmits light through a pixel electrode and a liquid crystal material adjacent to said pixel electrode, the display having at least 200 row lines per centimeter and a diagonal length of 1.27 centimeters or less;
- generating an image with the active matrix display;
- magnifying the image with a lens positioned along the single optical axis;
- and
- directing the magnified image through the lens along the single optical axis to an eye of the user.

A method of displaying images with a head mounted liquid crystal display system comprising;
- providing a support frame that is mounted on a user's head;
- providing a transmissive liquid crystal active matrix display mounted on the support frame, the display comprising a backlight source, an array of pixel circuits formed with a silicon material, the pixel circuits being bonded to an optically transmissive substrate with an adhesive layer, an array of pixel electrodes formed with a silicon material and that are each connected to a pixel circuit, and a row driver circuit and a column driver circuit formed with the silicon material and electrically connected to each pixel circuit the display having at least 400 row lines per centimeter and a diagonal length of 1.27 centimeters or less;
- generating an image with the active matrix display;
- magnifying the image with a lens, the lens, the backlight, and the active matrix display being aligned along a single optical axis;
- and
- directing the magnified image along the single optical axis coinciding with a line-of-sight of the user.

A method of displaying images with a direct view display system comprising;
- providing a support frame that supports the display system for viewing by a user's eye;
- providing an active matrix liquid crystal display and a display light source mounted on the support frame, the display comprising an array of pixel circuits an array of pixel electrodes formed with a silicon material and that are each connected to a pixel electrode, and a row driver circuit and a column driver circuit which are electrically connected to each pixel circuit the display having at least 400 row lines per centimeter and a diagonal length of 1.27 centimeters or less;
- generating an image with light source and the active matrix liquid crystal display;
- magnifying the image with a lens positioned along a single optical axis with the display light source and the active matrix liquid crystal display, the lens being positioned at a distance of less than 2.54 centimeters from the display;
- and
- directing the magnified image through the lens along the single optical axis coinciding with a line-of-sight of the user.
