Note 1:

Note 2:

The data are measured after LEDs are turned on for 5 minutes.

The definition of viewing angle:

LCM displays full white. The brightness is the average value of 9 Refer to the graph below marked by θ and Ф

measured spots. Measurement equipment SR-3A (1°)

Measuring condition:

- Measuring surroundings: Dark room

- Measuring temperature: Ta=25 ℃ .

- Adjust operating voltage to get optimum contrast at

the center of the display.

Note 3:

The definition of contrast ratio (Test LCM using SR-3A (1°)):

Note 4:

Contrast

Luminance When LCD is at “White” state

Definition of Response time. (Test LCD using BM-7A(2°)):

Ratio(CR)

=

Luminance When LCD is at “Black” state

The output signals of photo detector are measured

(Contrast Ratio is measured in optimum common electrode

when the input signals are changed from

voltage)

“black” to “white”(falling time)

and from “white” to “black”(rising time), respectively.

The response time is defined as

the time interval between the 10% and 90% of amplitudes.Refer to

figure as below.

Note 5:

Note 6:

Definition of Color of CIE1931 Coordinate and NTSC Ratio.

The luminance uniformity is calculated by using following formula.

△ Bp = Bp (Min.) / Bp (Max.)×100 (%)

Color gamut:

Bp (Max.) = Maximum brightness in 9 measured spots

Area of RGB triangle

S=

X100%

Bp (Min.) = Minimum brightness in 9 measured spots .

Area of NTSC triangle

Note 7:

Measured the luminance of white state at center point
