ILLUMINANT
Notes :
1. Contrast Ratio(CR) is defined mathematically as :
Surface Luminance with all white pixels
Contrast Ratio = ----------------------------------------------------------------------------
Surface Luminance with all black pixels
2. Surface luminance is the center point across the LCD surface 500mm from the surface with all
pixels displaying white. For more information see FIG 1.
3. Response time is the time required for the display to transition from to black(Rise Time, TrR)
and from black to white(Decay Time, TrD). For additional information see FIG 3.
4. Viewing angle is the angle at which the contrast ratio is greater than 10. The angles are
determined for the horizontal or x axis and the vertical or y axis with respect to the z axis
which
is normal to the LCD surface. For more information see FIG 5.
5. Optimum contrast is obtained by adjusting the LCD Threshold voltage(Vth & Vsat)

9.Inspection Criteria:
9.1 Inspection Conditions
9.1.1 Environmental Conditions
The environmental conditions for inspection shall be as follows
Room Temperature : 23±5°C
Humidity : 50±20%RH
9.1.2 The External Visual Inspection
With 1000±200 lux fluorescent lamp as the light source, the inspection was in
the distance of 30cm or more from the LCD to the inspector's eyes .
9.2 Light Method
1. Inspection is implemented over 30cm vertical distance and 30° incidence under 1000±200 lux.
(As showed below)
2. Viewing direction for inspection over 30cm far and is 45° against from LCD
( As showed below)
9.3 Classification of Defects
9.3.1 Major Defect
A major defect refers to a defect that may substantially degrade usability for product applications.

9.3.2 Minor Defect
A minor defect refers to a defect which is not considered to be able substantially degrade
the product application or a defect that deviates from existing standards almost unrelated
to the effective use of the product or its operation.
Notes: If the LCD/LCM’s cosmetic and display performance do not specify in
“inspection criterion”, it should be based on these delivered samples.
