Page 7: Product Overview
3. Product Overview The projector consists of DLP projector controller, Lamp controller, Power supply system, and System cooling controller. The DLP controller captures digital PC data and video data and then converts them into the DMD display device. The Lamp controller dominates the lamp’s power and synchronizes its frequency with color display sequence.

Page 44 6. IMAGE QUALITY SPECIFICATION: Scope ® This document specifies the image quality requirements applicable to the DLP .7XGA Type A and ® Series 450 Value Component Set. The Component Set provides the DLP . 7XGA Type A and Series 450 Value Projector with digital imaging functionality based on Digital Micromirror Device (DMD) technology.
Page 45 The Gray 10 screen is used to test for major light blemishes. All areas of the screen are colored a Microsoft Paintbrush gray 10 (green, red, and blue set at 10). NOTE: If linear degamma is not used then the Microsoft Paintbrush values must be adjusted to match the degamma table being used in order to generate an equivalent gray level on the test screen image.
Page 46 may not be returned to TI without prior approval by TI. Screens < Gray 10 shall not be used as a basis for rejecting a DMD for image quality.

Appendix 4 - Optical Measurement 1. Scope: This document describes critical optical related test definitions and Instructions for data or video projectors. The other general terminologies are specified in ANSI IT7.228-1997. 2. General Requirements 2.1. The unit under test should be allowed to stabilize without further adjustment for a minimum of 5 minutes, at nominal ambient room temperature of 25C, before making measurements.
Page 158 A.4 ANSI CONTRAST ANSI Contrast = Average lux value of the white rectangles/Average lux value of the black rectangles Contrast Ratio shall be determined from illuminance values obtained from a black-and-white ”chessboard” pattern consisting of 16 equal rectangles. The white rectangles shall be at 100% gray and the black rectangles at 0% gray.
Page 159 A.9 THROW RATIO Throw ratio = projection distance / the width of the projected image A.10 ZOOM RATIO Zoom ratio = maximum / minimum image diagonal size at a fixed projection distance A.11 FOCUS RANGE The minimum/maximum focus distance is the minimum/maximum projection distance (The distance between the outermost element of projection lens and screen), expressed in meter, at which the image is still at its acceptable focus level.(acceptable focus level is specified by FOCUS LIMIT SAMPLE approved by customer)
