HUD Design Checklist and Resources#
This module provides guidelines and design checklists for new developers to evaluate and validate their custom AR-HUD designs. In addition to the hardware and optical design resources provided for the respective evaluation modules, these checklists can be used to ensure a smooth development cycle and faster release to markets.
These checklists are not final and will continue to be updated. They do, however, provide a general overview of how TI designs their automotive EVMs. TI strongly encourages its users and customers to have design reviews with our engineers during the development phase highlighted in figure below.
Electronics#
When designing a new system, it is important to follow the reference designs of TI’s EVMs in conjunction with the respective datasheets. To help with the design process, TI has also created a design checklist to use so that important design constraints and considerations are kept in front of the designer at all times during the design process.
Optics#
This section contains guidelines for designing and evaluating the AR-HUD PGU optics.
- Optical system design checklist
- System overview and operating parameters
- Optical design method
- Setup
- Surface definition and windshield model example
- Optimization method
- Optical performance evaluation
- HUD Lumen budget estimate
- VID adjustability
- Pupil matching HUD mirrors to PGU
- Sunlight and glare notes
The following documents discuss the forementioned optical design topics. Optical designers are strongly encouraged to refer to these guidelines, in addition to the information at HUD Optics Primer.
Mechanics#
This section contains the guidelines required to utilize and mount the DLP553x, and DLP462x automotive chipsets. The DMD 3D-CAD files and System mounting concept design files are located under the ‘Device Documentation’ section of each product folder.
