  • LOCAL DIMMING SYSTEM FOR HEAD UP DISPLAY
    Publication number: 20250231438
    Abstract: A local dimming system for a head up display (HUD) according to the present invention comprises a light array, a Fresnel lens array, a lenticular lens system, and a liquid crystal display (LCD). The Fresnel lens array is operatively associated with the light array to provide a collimated backlight output to produce an image on the LCD. The Fresnel lens array focuses light from the light array while reflecting stray light, eliminating light bleed and reducing or eliminating a display-boundary or “postcard effect.” The Fresnel lens array is compact to enable HUD packaging necessary to configure the HUD for use in vehicles, while also removing the need for reflectors which create shadows on the LCD.
