Appendix A 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
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.
2. Measurements shall take place in a light proof room, where the
only source of illumination is the projector. Less than 1 lux of the
light on the screen shall be from any source other than the
projector.
3. All measurements shall be made on flat screens that do not provide
any advantage to the performance of the unit
4. All measurements shall be made at standard color temperature
setting, 100% white image (per ANSI IT7.228-1997), except where
noted
3.Practical Requirements
1. When measuring contrast manually, operators should not wear white clothing since
light reflected from white clothing can influence the measurement.
2. Unless otherwise specified, the projection lens is set in the widest zoom position since
zoom function can influence the measurement.
3. Measurement should be performed with Minolta Chromameter, Model CL-100, or
equivalent.
A1. ANSI BRIGHTNESS
ANSI Lumens = (L1+L2+L3+L4+L5+L6+L7+L8+L9)/9 (lux) x A(m^2)
A (Area) = W * H (m^2)
W: width of projected image (m)
H: height of projected image (m)

A2. BRIGHTNESS UNIFORMITY
Brightness Uniformity = Minimum (L10,L11,L12,L13)/ Average (L1,L2,L3,L4,L5,L6,L7,L8,L9)
A3. JBMA UNIFORMITY
JBMA Uniformity = Average (L1,L3,L7,L9)/ L5
A4. 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. Illuminance measurements shall be
made at the center of each of the rectangles.
A5. FOFO CONTRAST
FOFO Contrast = Lux value at the center of a solid white screen/the lux value at the center of a
solid black screen
A6. JBMA CONTRAST
JBMA Contrast = Average (L1,L2,L3,L4,L5,L6,L7,L8,L9) under solid white / Average
(L1,L2,L3,L4,L5,L6,L7,L8,L9) under solid black
A7. LIGHT LEAKAGE
Leakage = The maximum light leakage under a solid black pattern in or outside of the projected
image
A8. IMAGE DISTORTION
Keystone = (W2-W1)/ (W1+W2) x 100%
Vertical TV dist = (H1+H2-2xH3)/2H2 x100%
Horizontal TV dist = (W1+W2-2xW3)/2W1 x100%
W1: image width at image bottom
W2: image width at image top
W3: image width at the half image height.
H1: image height at image left
H2: image height at image right
H3: image height at half image
Note:
1. Keystone and Vertical TV Distortion are recommended for Front Projection Display
2. Vertical and Horizontal TV Distortion are recommended for Rear Projection Display
6

A9. THROW RATIO
Throw ratio = projection distance / the width of the projected image
A10. ZOOM RATIO
Zoom ratio = maximum / minimum image diagonal size at a fixed projection distance
A11. 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)
A12. COLOR
Color is expressed as (x, y) in 1931CIE chromaticity values
Note: Color is measured at the center of the screen that is entirely the measured color under
default brightness and contrast settings.
A13. ANSI COLOR
ANSI Color is expressed as (u, v) in 1976 CIE chromaticity values
Note: Color is measured at the center of the screen that is entirely the measured color under
default brightness and contrast settings.
A14. COLOR UNIFORMITY
Color Uniformity is the maximum color difference (△x, △y) between any two points out of
L1~L13
A15. ANSI COLOR UNIFORMITY
ANSI Color Uniformity: △u’v’= [(u’1-u’0)^2+(v’1-v’0)^2]^1/2
(u’0,v’0): the average color of L1~L13
(u’1,v’1): the spot with maximum deviation from (u’0,v’0)
A16. PROJECTION OFFSET
Projection Offset= Image height above projection lens optical axis / Total image height x 100%
Note: Optical engine should be kept horizontal attitude

Appendix B Design Verification Test Procedure
1. Purpose
This standard establishes the environmental specification for projector related products,
which defines the level of product performance and reliability in the field. It is not necessary the
intent of these specification to simulate a typical user environment, but rather to provide for a
level of product robustness that when applied over a wide range of manufacturing variability and
environmental usage conditions, which is recommended for product assurance testing reference.

Appendix C DMD Image Quality
1. SCOPE
This document specifies the image quality requirements applicable to the DLPTM XGA Component Set.
The Component Set provides the DLPTM XGA Projector with digital imaging functionality based on
Digital Micromirror Device (DMD) technology.
2. Definitions
2.1 Blemish
A blemish is an obstruction, reflection, or refraction of light that is visible, but out of focus in
the projected image under specified conditions of inspection (see Table 1). It is caused by a
particle, scratch, or other artifact located in the image illumination path.
2.2 Dark pixel
A single pixel or mirror that is stuck in the OFF position and is visibly darker than the
surrounding pixels.
2.3 Bright pixel
A single pixel or mirror that is stuck in the ON position and is visibly brighter than the
surrounding pixels.
2.4 Unstable pixel
A single pixel or mirror that does not operate in sequence with parameters loaded into
memory. The unstable pixel appears to be flickering asynchronously with the image.
2.5 Adjacent pixel
Two or more stuck pixels sharing a common border or common point, also referred to as a
cluster.
2.6 Streaks
Artifact resulting from locallized variation in mirror tilt angle relative to surrounding mirrors.
They are similar in appearance to window scratches but appear at the mirror level. Streaks
appear as faint diagonal or arcing patterns in the image.
2.7 Sea of Mirrors (SOM)
SOM is a rectangular array of off-state mirrors surrounding the active area.
2.8 Eyecatcher
A small localized light “spot” which has high spatial frequency and high differential
brightness. These are due to various DMD window or window aperture “defects” including:
digs, voids, particles and scratches.
2.9 Border Artifacts
All variations of these artifacts are acceptable under this image quality specification.
Border artifacts are a general category of image artifacts that may show up on screen in the
area outside of the active array. Border artifacts include: Exposed Bond Wires, Exposed
Metal 2, and Reflective Edge.
10

2.9.1 Bond Wires
Bond Wires attach the die to the superstructure. If visible, they will appear as short light
parallel lines outside of the Sea of Mirrors (SOM).
2.9.2 Exposed Metal 2
Exposed Metal 2 is due to a shift in positioning of either the die or the window aperture
which may allow light to be reflected off of the layer of metal 2 that is below the super
structure (mirrors). This defect is located at the outer edge of the SOM.
2.9.3 Reflective Edge
Reflective Edge is light that may reflect from the edge of the DMD’s window aperture onto
the projection screen. It will appear as a thin diffuse line outside of the SOM.
2.10 Two Zone Blue 60 Screen
The Two Zone Blue 60 screen is used to test for major dark blemishes. Refer to Figure 1 for
configuration. All areas of the screen are colored a Microsoft Paintbrush blue 60 (green and
red set at 0, blue set at 60).
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 blue level on the
test screen image.
2.11 Two Zone Gray 10 Screen
The Two Zone Gray 10 screen is used to test for major light blemishes. Refer to Figure 1 for
configuration. 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.
3. ACCEPTANCE REQUIREMENTS
3.1 Conditions of Acceptance
All DMD image quality defects must be determined under the following projected image
test conditions:
a. Projector degamma shall be linear.
b. Projector error diffusion shall be “off.”
c. Projector brightness and contrast settings shall be set to nominal.
