3. ABSOLUTE MAXIMUM RATINGS

Note: Absolute maximum ratings mean the product can withstand short-term, not more than 120 hours. If the product is a long time to withstand these conditions, the life time would be shorter.

4. ELECTRICAL CHARACTERISTICS (DC CHARACTERISTICS)

5. CTP CHARACTERISTICS

6. ELECTRO-OPTICAL CHARACTERISTICS

Note 1. Contrast Ratio(CR) is defined mathematically by the following formula. For more information see FIG 2.:
Contrast Ratio(CR) = Average Surface Luminance with all white pixels / Average Surface Luminance with all black pixels

Note 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

Note 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 9 points luminance by minimum luminance of 9 points luminance. For more information see FIG 2.

Note 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.

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

Note 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.

Note 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.

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

9. RELIABILITY TEST CONDITIONS

A. Inspection after test:

Inspection after 2~4 hours storage at room temperature, the sample shall be free from defects:

• Air bubble in the LCD;
• Seal leak;
• Non-display;
• Missing segments;
• Glass crack;
• Current is twice higher than initial value.

B. Remark:

• The test samples should be applied to only one test item.
• Sample size for each test item is 5~10pcs.
• Failure Judgment Criterion: Basic Specification, Electrical Characteristic, Mechanical Characteristic, Optical Characteristic.

10. 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.

10.1 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

10.2 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°C and normal humidity 60±15%RH)

10.3 Definition of Inspection Item.

A. Definition of inspection zone in LCD.

A diagram showing inspection zones A, B, and C on an 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)

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.

B. Definition of some visual defect

• Bright dot: Because of losing all or part function, bad pixel dots appear bright and the size is more than 50% of one dot in which LCD panel is displaying under black pattern.
• Dark dot: Dots appear dark and unchanged in size in which LCD panel is displaying under pure red, green, blue picture, or pure whiter picture.

10.4 Major Defect

10.5 Minor Defect

5.4.1 Polarizer Position

• (i) Shifting in position should not exceed the glass outline dimension.
• (ii) Incomplete covering of the viewing area due to shifting is not allowed.

5.4.2 Dirt on polarizer

Dirt which can be wiped easily should be acceptable.

5.4.3 Polarizer Dent & Air bubble

5.4.4 Polarizer scratch

• (i) If the polarizer scratch can be seen after cover assembling or in the operating condition, judge by the linear defect of 5.3.
• ( ii ) If the polarizer scratch can be seen only in non-operating condition or some special angle, judge by the following:

5.4.5 MURA

Using 3% ND filter, it's NG if it can be seen in R,G,B picture.

White/Black dot (MURA)

Visible under: ND3%; D≤0.15mm, Acceptable; 0.15mm<D≤0.5mm, N≤4; D>0.5mm, Not allowable.

6. Glass defect

• Crack
  Cracks are not allowed.
• (ii) TFT chips on corner
  A diagram illustrating TFT chips on the corner of the glass, with dimensions X, Y, Z and acceptable quantities N.
• (iii) Usual surface crack
  A diagram illustrating a usual surface crack on the glass, with dimensions X, Y, Z and acceptable quantities N. It is only applicable to the upper glass of LCD.
