Note：
The parameter is slightly changed by temperature, driving voltage and materiel
Note 1: The data are measured after LEDs are turned on for 5 minutes. LCM displays full white. The brightness isthe average value of 9 measured spots. Measurement equipment PR-705 (Φ5mm)
Measuring condition:
Measuring surroundings: Dark room.
Measuring temperature: Ta=25℃.
Adjust operating voltage to get optimum contrast at the center of the display.
Measured value at the center point of LCD panel after more than 5 minutes while backlight turning on.

Note 2: 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 5: Definition of Response time. (Test LCD using DMS501):
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 timeinterval between the 10% and 90% of amplitudes.Refer to figure as below.

7. PRECAUTIONS FOR USE OF LCD MODULESPRELIMINARY

7.1 Handling Precautions
7.1.1 The display panel is made of glass. Do not subject it to a mechanical shock by dropping itfrom a high place, etc.
7.1.2 If the display panel is damaged and the liquid crystal substance inside it leaks out, be sure
not to get any in your mouth, if the substance comes into contact with your skin or clothes,
promptly wash it off using soap and water.
7.1.3 Do not apply excessive force to the display surface or the adjoining areas since this may
cause the color tone to vary.
7.1.4 The polarizer covering the display surface of the LCD module is soft and easily scratched.
Handle this polarizer carefully.
7.1.5 If the display surface is contaminated, breathe on the surface and gently wipe it with a soft
dry cloth. If still not completely clear, moisten cloth with one of the following solvents:— Isopropyl alcohol— Ethyl alcohol
Solvents other than those mentioned above may damage the polarizer. Especially, do not use
the following:— Water— Ketone— Aromatic solvents
7.1.6 Do not attempt to disassemble the LCD Module.
7.1.7 If the logic circuit power is off, do not apply the input signals.
7.1.8 To prevent destruction of the elements by static electricity, be careful to maintain anoptimum work environment.
a. Be sure to ground the body when handling the LCD Modules.
b. Tools required for assembly, such as soldering irons, must be properly ground.
c. To reduce the amount of static electricity generated, do not conduct assembly and otherwork under dry conditions.
d. The LCD Module is coated with a film to protect the display surface. Be care when peeling off
this protective film since static electricity may be generated.

7.2 Storage precautions
7.2.1 When storing the LCD modules, avoid exposure to direct sunlight or to the light offluorescent lamps.
7.2.2 The LCD modules should be stored under the storage temperature range. If the LCD
modules will be stored for a long time, the recommend condition is:
Temperature :0℃ ～ 40℃

Relatively humidity: ≤80%
7.2.3 The LCD modules should be stored in the room without acid, alkali and harmful gas.
7.3 The LCD modules should be no falling and violent shocking during transportation, andalso should avoid excessive press, water, damp and sunshine.
