TI DLP System Design: Optical Module Specifications
Abstract
The objective of this application note is to help product developers better understand optical module specifications and related system design considerations. This information helps expedite product development and conversations with optical module manufacturers (OMM).
This document focuses on projection optical modules that incorporate Texas Instruments' DLP Display chips and are designed to project an image onto a surface for a variety of applications, including smartphones, tablets, display projectors, smart home displays, digital signage, AR glasses, and more.
Prior to reading this application note, it is recommended to read the Getting Started with DLP Display Technology application note.
The DLP Optical Design Guidelines presentation is mentioned throughout this application note. The presentation provides a comprehensive overview of the guidelines specific to designing an optical system with DLP Products and enables customers throughout the design process.
Please note that the terms optical engine and light engine are sometimes used in the projection industry. For consistency, this document uses the term optical module.
