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 is the average value of 9 measured spots. Measurement equipment
PR-705 (Φ8mm)
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 whilebacklight 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 time interval between the 10% and 90% ofamplitudes.Refer to figure as below.

9. Precautions for Use of LCD Modules9.1 Handling Precautions
9.1.1 The display panel is made of glass. Do not subject it to a mechanical shockby dropping it from a high place, etc.
9.1.2 If the display panel is damaged and the liquid crystal substance inside itleaks 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.
9.1.3 Do not apply excessive force to the display surface or the adjoining areas
since this may cause the color tone to vary.
9.1.4 The polarizer covering the display surface of the LCD module is soft andeasily scratched. Handle this polarizer carefully.
9.1.5 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
9.1.6 Do not attempt to disassemble the LCD Module.
9.1.7 If the logic circuit power is off, do not apply the input signals.
9.1.8 To prevent destruction of the elements by static electricity, be careful tomaintain an optimum 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 properlyground.
c. To reduce the amount of static electricity generated, do not conduct
assembly and other work under dry conditions.

ATM0220B14F(ZETTLER DISPLAYS) TFT MODULE SPEC V1.0
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 begenerated.
9.2 Storage precautions
9.2.1 When storing the LCD modules, avoid exposure to direct sunlight or to thelight of fluorescent lamps.
9.2.2 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%

9.2.3 The LCD modules should be stored in the room without acid, alkali andharmful gas.
9.3 The LCD modules should be no falling and violent shocking duringtransportation, and also should avoid excessive press, water, damp andsunshine.
