Systems and methods are disclosed for displaying data on a head's-up display screen. Multiple forms of data can be selectively displayed on a semi-transparent screen mounted in the user's normal field of view. The screen can either be mounted on the user's head, or mounted on a moveable implement and positioned in front of the user. A user interface is displayed on the screen including a moveable cursor and a menu of computer control icons. An eye-tracking system is mounted proximate the user and is employed to control movement of the cursor. By moving and focusing his or her eyes on a specific icon, the user controls the cursor to move to select the icon. When an icon is selected, a command computer is controlled to acquire and display data on the screen. The data is typically superimposed over the user's normal field of view.

A head-up display includes a projection system and a window having a target area where a reflective polarizer is positioned to reflect light from the projection system to a viewing area. Light from the projection system is p-polarized and strikes exposed window surface(s) at an acute angle to reduce or eliminate multiple or “ghost” images. The acute angle is closely matched to a Brewster angle of the exposed window surface(s). The reflective polarizer includes a multilayer stack with refractive indices of individual layers chosen to reflect p-polarized light substantially more than s-polarized light over a wide angular range that includes the acute angle. The reflective polarizer also can reflect infrared light to reduce cabin heating from solar radiation.

A safety critical, time sensitive data system for projecting safety / mission critical data onto a display pair of Commercial Off The Shelf (COTS) light weight projection glasses or monocular creating a virtual 360° HUD (Heads Up Display) with 6 degrees of freedom movement. The system includes the display, the workstation, the application software, and inputs containing the safety / mission critical information (Current User Position, Total Collision Avoidance System—TCAS, Global Positioning System—GPS, Magnetic Resonance Imaging—MRI Images, CAT scan images, Weather data, Military troop data, real-time space type markings etc.). The workstation software processes the incoming safety / mission critical data and converts it into a three dimensional space for the user to view. Selecting any of the images may display available information about the selected item or may enhance the image. Predicted position vectors may be displayed as well as 3D terrain.

A projection system, such as a system suitable for head-up displays in automobiles, includes a laser projection source (101) and a scanner (102). Light from the laser projection source (101) is scanned across a projection surface (104), which can be a car's windshield. The projection surface (104) includes a buried numerical aperture expander (105) capable of reflecting some light and transmitting other light. The system may also include an image projection source (551) capable of presenting high-resolution images on a sub-region (552) of the projection surface (604) that has a optical relay (650) disposed therein.

A multicolor organic light emitting device employs vertically stacked layers of double heterostructure devices which are fabricated from organic compounds. The vertical stacked structure is formed on a glass base having a transparent coating of ITO or similar metal to provide a substrate. Deposited on the substrate is the vertical stacked arrangement of three double heterostructure devices, each fabricated from a suitable organic material. Stacking is implemented such that the double heterostructure with the longest wavelength is on the top of the stack. This constitutes the device emitting red light on the top with the device having the shortest wavelength, namely, the device emitting blue light, on the bottom of the stack. Located between the red and blue device structures is the green device structure. The devices are configured as stacked to provide a staircase profile whereby each device is separated from the other by a thin transparent conductive contact layer to enable light emanating from each of the devices to pass through the semitransparent contacts and through the lower device structures while further enabling each of the devices to receive a selective bias. The devices are substantially transparent when de-energized, making them useful for heads-up display applications.

Methods and apparatus are provided for compensating a liquid crystal display for changes in brightness level. The apparatus comprises a variable brightness back-light optically coupled to a display panel whose properties depend upon back-light brightness. An electrical circuit measures back-light brightness and / or display flicker and sends this information to a controller. The controller automatically determines a display panel compensation signal based on back-light brightness and / or display flicker, and sends this compensation signal to the display panel to optimize the display panel properties for the commanded or observed back-light brightness level or flicker level so as to, for example, minimize display panel flicker and / or ghost image retention. Such automatic compensation is especially useful for head-up displays that must accommodate large variations in display brightness, e.g., from starlight to full sun, and / or for large, bright projection displays adapted to operate in different ambient light conditions where back-light brightness variation is desirable.

A heads-up display (HUD) adaptor for use in combination with an existing heads-up display (HUD) unit, wherein the HUD adaptor receives an electronic peripheral device in order to display electronic data and information from the peripheral on the screen of the existing HUD unit on a vehicle's windshield. The HUD adaptor includes a proximal end, a distal end and a cable therebetween; wherein the proximal end has a first adaptor plug; and the distal end has a second adaptor plug. The existing HUD unit includes a heads-up display screen on a front windshield of the vehicle and a heads-up display control unit is positioned within a control panel on a steering wheel of the vehicle for controlling each of the electronic peripherals. The HUD unit includes a USB panel member having a plurality of USB receiving ports for receiving one or more of the HUD adaptors therein. The first adaptor plug of the HUD adaptor is received within a receiving port of an electronic communication device; and the second adaptor plug of the HUD adaptor is received within one of the plurality of the USB receiving ports of the USB panel member for electronically connecting the HUD adaptor to the HUD control unit.
