A visual display system includes a first image source for producing a first image containing symbological information using a vector drawing system. A second image source produces a second image containing video, graphical, and/or symbology information with a brightness lower than the brightness of the first image. A light combining optical element combines the light from the first and the second image sources. An image forming optical system receives the combined light from the light combining optical element for forming a new image comprising a superimposition of the first image and the second image at a final image plane of the system. A light receiving element, located at the final image plane of the system, receives the new image from the image forming optical system and adjusts the characteristics of the light from the new image to generate a final image for direct or indirect viewing. The visual display system is particularly adaptable for use in a Heads-Up-Display (HUD) system.

Visual display system using multiple image sources and heads-up-display system using the same

A phosphor screen for image forming including phosphor material being excitable by light in a wavelength &#x3bb;. The phosphor screen receives an optical image from an image forming optical system and produces the optical image at a second wavelength &#x3bb;. The phosphor screen includes a phosphor layer comprising the phosphor material. A short-pass reflective coating is positioned on a first side of the phosphor layer. The short-pass reflective coating transmits the wavelength &#x3bb;and reflects the wavelength &#x3bb;. A long-pass reflective coating is positioned on a second side of the phosphor layer. The long-pass reflective coating transmits the wavelength &#x3bb;and reflects the wavelength &#x3bb;. A first substrate is positioned over the short-pass reflective coating. The first substrate is formed of optically clear and thermal conductive material. A second substrate is positioned over the long-pass reflective coating. The second substrate is formed of long-pass absorptive optical filter material that transmits the wavelength &#x3bb;and absorbs wavelength &#x3bb;from ambient light to prevent the phosphor layer from being excited by the ambient light. The phosphor screen may alternatively be used for a direct-view visual display apparatus. These principles can also be utilized for backlighting and general illumination applications.

Phosphor screen and displays systems

A display system is disclosed. The display system includes a light source and a display element illuminated by the light source. The display system also includes a first liquid crystal polymer compensation film layer that is disposed adjacent to the first side of the display element. The display also includes a second liquid crystal polymer compensation film layer disposed adjacent a second side of the display element. Further, the display system includes a third liquid crystal polymer compensation film layer that is disposed adjacent the second liquid crystal polymer compensation film layer.
