SCREEN CONFIGURATION FOR DISPLAY SYSTEM

摘要

An optical configuration for a display system includes a front screen, a first microlens array, and a second microlens array. The front screen has optical properties to absorb ambient light and let image light through. The first microlens array is coupled to receive the image light from a pixel array of an image generation layer. The second microlens array is disposed between the front screen and the first microlens array. The second microlens array is offset from the first microlens array by approximately a focal length of microlenses in the first microlens array. The second microlens array is coupled to direct the image light received from the first microlens array through front screen. Each of the microlenses in the first microlens array is axially aligned with a corresponding microlens in the second microlens array.
