Notes :
1. Viewing angle is the angle at which the contrast ratio is greater than 10. The viewing
angles are determined for the horizontal or 3, 9 o’clock direction and the vertical or 6,
12 o’clock direction with respect to the optical axis which is normal to the LCD surface
(see Figure1).
2. Contrast measurements shall be made at viewing angle of
Θ=
0 and at the center of
the LCD surface. Luminance shall be measured with all pixels in the view field set first
to white, then to the dark (black) state (see Figure1). Luminance Contrast Ratio (CR) is
defined mathematically as CR = Luminance when displaying a white raster / Luminance
when displaying a black raster.
3. Reference only / Standard Front Surface Treatment Measured with green cover glass.
The color chromaticity coordinates specified in Table 4 shall be calculated from the
spectral data measured with all pixels first in red, green, blue and white. Measurements
shall be made at the center of the panel.
4. The luminance value of 400 cd/m2 means the brightness of PWM is 100%. The
luminance value of 30 cd/m2 means the brightness of lower PWM. CTF means that
measure brightness at only center point at Figure 2.
