Note:
*1. This rating applies to all parts of the module. And should not be exceeded.
*2. The operating temperature only guarantees operation of the circuit. The contrast, response speed,
and the other specification related to electro-optical display quality is determined at the room temperature, T OP =25 ℃ .
*3. Ambient temperature when the backlight is lit (reference value).
*4. Any Stresses exceeding the Absolute Maximum Ratings may cause substantial damage to the device. Functional operation of this
device at other conditions beyond those listed in the specification is not implied and prolonged exposure to extreme conditions may
affect device reliability.

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
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 ):
Note 4:
Contrast
Luminance When LCD is at “White” state
Definition of Response time. (Test LCD using BM-7A):
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
