2 Use Case Considerations

How the pico projection system will be used in the end product is fundamental in determining the required optical module specifications.

Table 2-1 Use Case Considerations
Use Case ConsiderationsOptical Module Specifications Impacted
Size of the product and space available for projection systemSize, power consumption, thermal management solution
Ambient lighting environmentBrightness, image size, DLP IntelliBright™algorithms
Battery-powered operation or plugged in to a power outletBrightness
Distance from the projection surface and image size targetThrow ratio
Type of video content (for example, movies, signage, PowerPoint presentations, and so forth)Resolution, brightness, contrast ratio, color management
Projection surface shape (flat or curved)Depth of focus
Orientation (distance, angle, position) between the optical module and the projection surfaceThrow ratio, keystone correction, offset
Operating environment temperatureThermal management solution
Maximum allowable bill of materials costBrightness, resolution, throw ratio

This is just a sample of the type of questions that should be answered by the product developer to better define the required specifications of a DLP Pico projection optical module.
