Note 1: 
The data are measured after LEDs are turned on for 5 minutes. 
LCM displays full white. The brightness is the average value of 9 
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 2: 
The definition of viewing angle:

 

 

Refer to the graph below marked by 

θ 

and 

Ф

 

 

 

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

Contrast 

Ratio(CR) 

= 

Luminance When LCD is at “White” state 
Luminance When LCD is at “Black” state 

(Contrast Ratio is measured in optimum common electrode 
voltage)

 

 
Note 4: 
Definition of Response time. (Test LCD using BM-7A(2°)): 
The output signals of photo detector are measured 
when the input signals are changed from  
“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: 
Definition of Color of CIE1931 Coordinate and NTSC Ratio. 
 
Color gamut: 

S= 

Area of RGB triangle 

X100% 

Area of NTSC triangle 

 

 

 

Note 6: 
The luminance uniformity is calculated by using following formula. 

△

Bp = Bp (Min.) / Bp (Max.)×100 (%) 

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

. 

 

 
Note 7: 
Measured the luminance of white state at center point
