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 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. 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 conrast 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 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,CIE The test data is base on TOPCON’s
BM-5 photo detector.
Note 8. For TFT module, Gray scale reverse occurs in the direction of panel viewing angle.
