Note

1. Contrast Ratio(CR) is defined mathematically by the following formula. For more information see FIG 2.:

2. Surface luminance is the LCD surface from the surface with all pixels displaying white. For more information see FIG 2.
   Lv=Average Surface Luminance with all white pixels (P1,P2,P3,P4,P5,P6,P7,P8,P9)

3. The uniformity in surface luminance（WHITE）is determined by measuring luminance at each test position 1 through 9, and then dividing the maximum luminance of 9points luminance by minimum luminance of 9 points luminance. For more information see FIG 2.

4. Response time is the time required for the display to transition from White to black(Rise Time, Tr) and from black to white(Decay Time, Tf). For additional information see FIG 1.

5. CIE (x, y) chromaticity ,The x,y value is determined by screen active area position 5.
   For more information see FIG 2.

6. Viewing angle is the angle at which the contrast ratio is greater than a specific value.
   For TFT module, the specific value of contrast ratio is 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 3.

7. For Viewing angle and response time testing, the testing data is base on Autronic-Melchers’s ConoScope. Series Instruments. For contrast ratio, Surface Luminance,Luminance uniformity and CIE，the testing data is base on BM-7 photo detector.

8. For TN type TFT transmissive module, Gray scale reverse occurs in the direction of panel viewing angle.

INSPECTION CRITERION

This specification is made to be used as the standard of acceptance/rejection criteria for TFT-LCD/IPS TFT-LCD module product, and this specification is applicable only in the case that the size of module equal to or exceed than 3.5 inch.

Sample plan
Sampling plan according to GB/T2828.1-2003/ISO 2859-1：1999 and ANSI/ASQC Z1.4-1993,normal level 2 and based on:

Major defect: AQL 0.65
Minor defect: AQL 1.5

Inspection condition
Viewing distance for cosmetic inspection is about 30cm with bare eyes, and under an environment of 20~40W light intensity, all directions for inspecting the sample should be within 45°against perpendicular line. (Normal temperature 20~25℃and normal humidity 60 ±15%RH )

Definition of Inspection Item
A、 Definition of inspection zone in LCD.

• Zone A: character/Digit area
• Zone B: viewing area except Zone A (Zone A + Zone B=minimum Viewing area)
• Zone C: Outside viewing area (invisible area after assembly in customer’s product)
  Fig.1 Inspection zones in an LCD
  Note: As a general rule, visual defects in Zone C are permissible, when it is no trouble for quality and assembly of customer’s product.
