Note2: Definition of response time:
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.

5. PRECAUTION RELATING PRODUCT HANDLING
5.1 SAFETY
5.1.1 If the LCD panel breaks , be careful not to get the liquid crystal to touch your skin.
5.1.2 If the liquid crystal touches your skin or clothes , please wash it off immediately by
using soap and water.
5.2 HANDLING
5.2.1 Avoid any strong mechanical shock which can break the glass.
5.2.2 Avoid static electricity which can damage the CMOS LSI—When working with the
module , be sure to ground your body and any electrical equipment you may be using.
5.2.3 Do not remove the panel or frame from the module.
5.2.4 The polarizing plate of the display is very fragile. So , please handle it very
carefully ,do not touch , push or rub the exposed polarizing with anything harder
than an HB pencil lead (glass , tweezers , etc.)
5.2.5 Do not wipe the polarizing plate with a dry cloth , as it may easily scratch the
surface of plate.
5.2.6 Do not touch the display area with bare hands , this will stain the display area.
5.2.7 Do not use ketonics solvent & aromatic solvent. Use with a soft cloth soaked with
a cleaning naphtha solvent.
5.2.8 To control temperature and time of soldering is 320±10℃and 3-5 sec.
5.2.9 To avoid liquid (include organic solvent) stained on LCM .
5.3 STORAGE
5.3.1 Store the panel or module in a dark place where the temperature is 25℃ ±5℃
and the humidity is below 65% RH.
5.3.2 Do not place the module near organics solvents or corrosive gases.
5.3.3 Do not crush , shake , or jolt the module.
5.4 TERMS OF WARRANTY
5.4.1 Applicable warrant period
The period is within thirteen months since the date of shipping out under normal
using and storage conditions.
5.4.2 Unaccepted responsibility
This product has been manufactured to your company’s specification as a part for
use in your company’s general electronic products. It is guaranteed to perform
according to delivery specifications. For any other use apart from general
electronic equipment , we cannot take responsibility if the product is used in
