8 Example Optical Module Specification Table

Developers can use this table to help accelerate communication with DLP Pico projection optical module manufacturers. By listing target and boundary specifications, the OMM will be able to more quickly identify the right solution. The target spec should be the ideal specification, within reason, and the boundary spec should be the minimum or maximum acceptable specification.

Included in the table is a column with example target specifications for a smartphone or tablet built-in pico projection application.
