Abstract
This disclosure describes techniques to integrate multiple distinct modules of a display system for augmented reality eyewear into a single, monolithic unit or carrier. Per the techniques, a highly integrated, compact assembly replaces conventional multi-module systems. This is achieved through the design and manufacturing of a waveguide (WG) carrier that serves as a monolithic housing. The carrier is precisely molded to incorporate physical characteristics and features necessary for passively installing various optical and electronic components. Such components may include the waveguide, lenses for a light engine assembly (LEA), and lenses for a camera module. Active alignment (AA) of critical sensors within the integrated opto-mechanical (OM) module is performed to achieve optimal optical performance metrics of the display panel and to ensure precise internal optical alignment of the camera sensor relative to the LEA and WG components. The monolithic housing design addresses the issue of tolerance stack-up and provides more precise and consistent optical alignment. The integrated single-assembly process can also reduce manufacturing failures, improve yield, and achieve lower production costs.
