Note 1: Contrast Ratio = Average Surface Luminance with all white pixels (P
Note 2: Surface luminance is the LCD surface from the surface with all pixels displaying white.
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.
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 2.
Note 5: CIE (x, y) chromaticity: The x,y value is determined by measuring luminance at each test position 1 through 5,and
then taking 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 additional information see Fig 1.
Fig.1 (Definition of Viewing Angle)
Fig. 2 (The response time is defined as the time interval between the 10% and 90% amplitudes. Refer to figure below.)
