Note (1)
Definition of Viewing Angle (θx, θy):
Note (2) Definition of Contrast Ratio (CR):
The contrast ratio can be calculated by the following expression and figure
below.
Contrast Ratio (CR) = L255 / L0
L255: Luminance of gray level 255
L 0: Luminance of gray level 0
CR = CR (5)
CR (X) is corresponding to the Contrast Ratio of the point X at Figure in Note
(5).

Note (4) Measurement Setup:
The LCD module should be stabilized at given temperature for 20 minutes
to avoid abrupt temperature change during measuring. In order to stabilize
the luminance, the measurement should be executed after lighting Backlight
for 20 minutes in a windless room.

Luminance is measured at the center measurement position “C” on the
LCD panel. The optical axis of the luminance meter shall be aligned with
the normal of the panel surface. The measuring distance between the
photometer and the surface of the panel is defined as:
Md (cm) = diagonal of the panel (cm) X 1.5 with minimum distance 50
cm.
The panel is rotated around a vertical axis which passes the center of
the display by changing the azimuthal angle to +30°. The distance
between the panel and the photometer remains unchanged and the
measured point is exact the same as the previous measured point.
The photometer is then rotated by changing its azimuthal angle with the
fixed distance to the panel. Luminance at points “L” and “R” are given:
L
min, +30
°and L
max, +30
°
The LCD panel is then rotated to another azimuthal angle to -30°; and
L
min, -30
°and L
max, -30
°are obtained by using the same procedure.
The Luminance Uniformity (L R ) is calculated as follow:
L R = ((L
max, +30
°/ L
min, +30
°)+( L
max, -30
°/ L
min, -30
°)) / 2.

Note (6) Definition of TCO 99 Luminance Contrast (Angular-dependent) (Cm):
Luminance contrast is measured at the center point of the LCD panel
“C” along with the normal of the display with the same distance described
in Note 13. The display is then rotated around the vertical axis by
changing its azimuthal axis to +30°; and this gives:
L 255
G.L., +30
°and L
0 G.L., +30
°.
The LCD panel is then rotated to azimuthal angle to -30°; and L
0 G. L., -
30
°and L
255 G.L., -30
°are obtained by using the same procedure. The
Luminance Contrast (Cm) is calculated:
Cm = (L 255
G. L.
- L
0 G.L.
)/ (L 255
G. L.
+ L
0 G.L
)
For both +30°and -30°. The lower value for Cm is reported.
