Title:
SYSTEM AND OPERATION METHOD FOR HOLOGRAPHIC HEAD-UP DISPLAY BASED ON MICROMIRROR ARRAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2022/107962
Kind Code:
A1
Abstract:
The present invention relates to an operation method for a holographic head-up display based on a micromirror array element, wherein a first image and a second image are formed in a holographic HUD module for an operator of the operation method to observe a hologram image in two different regions, and in order to display a short distance-long distance image, one in-depth 3D image is formed via a micromirror array element (30) by using a first image display unit (10) and a second image display unit (20) simultaneously, and the 3D image thus formed is depicted as a hologram image via a HOE element (40). In addition, the present invention relates to a holographic head-up display system based on a micromirror array element, comprising: a first image display unit (10) displaying a short-distance image; a second image display unit (20) displaying a long-distance image; a micromirror array element unit (30) placing images displayed on the first image display unit and the second image display unit such that the images are spatially different from each other; and a HOE element unit (40) transforming a 3D image formed by the micromirror array element unit into a hologram HUD image. By using the micromirror array element to display two different distances, a long distance and a short distance, according to a velocity or an environment around a vehicle, the present invention has a significant effect of providing a safe and comfortable hologram HUD image that takes into consideration a driver's focus adjustment function.
