Integrated head-up and panel display unit
First Claim
1. An integrated head-up and panel display system comprising:
- a first image source for projecting a HUD image;
a second image source for projecting a panel image;
a combiner for directing HUD image light to a system exit pupil;
a panel screen for display of panel image light; and
optical selector means arranged to substantially reflect light from said first image source toward said combiner and to substantially transmit light therethrough from said second image source toward said panel screen.

Abstract
An integrated head-up and panel display system for aircraft cockpits and the like is disclosed. The system utilizes a wavelength-sensitive fold mirror to separate the HUD image and the panel images. The system includes a monochromatic HUD image source for projecting the HUD image toward the fold mirror, and at least one panel display image source for projecting panel imagery toward the fold mirror. The transmission function of the fold mirror is notched at the wavelength of the monochromatic HUD image source. Thus, the fold mirror reflects the HUD image in the direction of the HUD optical combiner which reflects the HUD image to the system exit pupil. The fold mirror is adapted to transmit light in the visible spectra outside the narrow bandwidth of the HUD image source, so that the panel image is transmitted through the fold mirror to a look-down display screen assembly. The screen assembly may be a diffusion screen for providing an image plane at the screen, or an assembly of optical elements for providing a panel image superimposed at the system exit pupil.

20. An integrated head-up and panel display system comprising:
-
a first image source for projecting a HUD image; a second image source for projecting a panel image; a display system housing having a front panel portion facing a system user; a HUD fold mirror disposed in the housing between the second image source and the front panel portion for substantially reflecting HUD image light from the first image source; a combiner mounted on the housing adjacent the front panel portion for receiving HUD image light reflected from the fold mirror and directing it toward the system user; a panel screen mounted on the front panel portion of the housing for receiving panel image light from the second image source transmitted through said fold mirror thereof visible to the user; and wherein said HUD image and said panel image are displayed simultaneously. - View Dependent Claims (21, 22, 23)
