Note 1. Contrast Ratio(CR) is defined mathematically as below, for more information see  Figure 3 .

Note 2. Surface luminance is the LCD surface from the surface with all pixels displaying white. For more information, see Figure 3 .

Note 3. The uniformity in surface luminance δ WHITE is determined by measuring luminance at each test position 1 through 5, and then dividing the maximum luminance of 5 points luminance by minimum luminance of 5 points luminance. For more information, see Figure 3 .

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. The test equipment is Autronic-Melchers’s ConoScope series.

Note 5. CIE (x, y) chromaticity, the x, y value is determined by measuring luminance at each test position 1 through 5, and then make average value.

Note 6. Viewing angle is the angle at which the contrast ratio is greater than 2. For TFT module 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 Figure 4.

Note 7. For viewing angle and response time testing, the testing data is based on Autronic-Melchers’s ConoScope series. Instruments for Contrast Ratio, Surface Luminance, Luminance Uniformity, CIE the test data is based on TOPCON’s BM-5 photo detector.

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

11 Electrostatic Discharge Air: ±8KV 150pF/330Ω 5 times

Contact: ±4KV 150pF/330Ω 5 times

12 Hitting Test 1,000,000 times in the same point

Hitting pad: tip R3.75mm, Silicone rubber, Hardness: 40deg.

Load: 2.45N

Hitting speed: Twice/sec

Electric load: none

Test area should be at 1.8mm inside of insulation.

13 Pen Sliding Durability Test 100,000 times minimum

Hitting pad: tip R0.8mm plastic pen

Load: 1.47N

Sliding speed: 60 mm/sec

Electric load: none

Test area should be at 1.8mm inside of insulation.

Remark:

1. The test samples should be applied to only one test item.

2. Sample size for each test item is 5~10pcs.

3. For Damp Proof Test, Pure water (Resistance

10MΩ) should be used.

4. In case of malfunction defect caused by ESD damage, if it would be recovered to normal state after resetting, it would be judge as a good part.

5. EL evaluation should be excepted from reliability test with humidity and temperature: Some defects such as

black spot/blemish can happen by natural chemical reaction with humidity and Fluorescence EL has.

6. Failure Judgment Criterion: Basic Specification, Electrical Characteristic, Mechanical Characteristic, Optical

Characteristic.
