Notes:
1. In case of below 0 ℃， the response time of liquid crystal (LC)becomes slower .
2. The color of panel becomes darker than normal one. Level of retardation depends on temperature,
because of LC's characteristics.
3. If the module is above these absolute maximum ratings. It may become permanently damaged.
Using the module within the following electrical characteristic conditions are also exceeded,
the module will malfunction and cause poor reliability.

Note1: The LED driving condition is defined for each LED module (6 LED Serial,).For each
LED:
I F =20mA, V F (1/6) =3.2V.
Note2: Under LCM operating, the stable forward current should be inputted. And forward
voltage is for reference only.
Note3: I F is defined for one channel LED. Optical performance should be evaluated at
Ta=25 ℃ only If LED is driven by high current, high ambient temperature & humidity
condition. The life time of LED will be reduced. Operating life means brightness goes
down to 50% initial brightness. Typical operating life time is estimated data.

5.1 INTERFACE TIMING
5.2 Reset Timing
Notes:
1. The reset cancel includes also required time for loading ID bytes, VCOM setting and other settings from
NVM (or similar device) to
registers. This loading is done every time when there is HW reset cancel time (tRT) within 5 ms after a rising
edge of RESX.
2. Spike due to an electrostatic discharge on RESX line does not cause irregular system reset according to the
table below:

3. During the Resetting period, the display will be blanked (The display is entering blanking sequence, which
maximum time is 120
ms, when Reset Starts in Sleep Out – mode. The display remains the blank state in Sleep In – mode.) and then
return to Default condition
for Hardware Reset.
4. Spike Rejection also applies during a valid reset pulse as shown below:
5. When Reset applied during Sleep In Mode.
6. When Reset applied during Sleep Out Mode.
7. It is necessary to wait 5msec after releasing RESX before sending commands. Also Sleep Out command
cannot be sent for
120msec.

Note 1: Definition of optical measurement system.
The optical characteristics should be measured in dark room. After 5 Minutes operation, the optical
properties are measured at the center point of the LCD screen. All input terminals LCD panel must
be ground when measuring the center area of the panel.

The response time is defined as the LCD optical switching time interval between “White” state and
“Black” state. Rise time (T ON ) is the time between photo detector output intensity changed from 90%
to 10%. And fall time (T OFF ) is the time between photo detector output intensity changed from 10% to
90%.
Note 5: Definition of color chromaticity (CIE1931)
Color coordinates measured at center point of LCD.
Note 6: Definition of Luminance Uniformity
Active area is divided into 9 measuring areas (Refer Fig. 2). Every measuring point is placed at the
center of each measuring area.
Luminance Uniformity (U) = Lmin/ Lmax
L-------Active area length W----- Active area width
Lmax: The measured Maximum luminance of all measurement position.
Lmin: The measured Minimum luminance of all measurement position.
Note 7: Definition of Luminance:

10 Precautions for Use of LCD Modules
10.1 Handling Precautions
10.1.1 The display panel is made of glass. Do not subject it to a mechanical shock by dropping it
from a high place, etc.
10.1.2 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.
10.1.3 Do not apply excessive force to the display surface or the adjoining areas since this may
cause the color tone to vary.
10.1.4 The polarizer covering the display surface of the LCD module is soft and easily scratched.
Handle this polarizer carefully.
10.1.5 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:
－ Ketone
－ Aromatic solvents
10.1.6 Do not attempt to disassemble the LCD Module.
10.1.7 If the logic circuit power is off, do not apply the input signals.
10.1.8 To prevent destruction of the elements by static electricity, be careful to maintain an optimum
work environment.
10.1.8.1 Be sure to ground the body when handling the LCD Modules.
10.1.8.2 Tools required for assembly, such as soldering irons, must be properly ground.
10.1.8.3 To reduce the amount of static electricity generated, do not conduct assembly and other
work under dry conditions.
10.1.8.4 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.
10.2 Storage precautions
10.2.1
When storing the LCD modules, avoid exposure to direct sunlight or to the light of
fluorescent lamps.
10.2.2 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%
10.2.3 The LCD modules should be stored in the room without acid, alkali and harmful gas.
10.3
Transportation Precautions
10.3.1 The LCD modules should be no falling and violent shocking during transportation, and also
should avoid excessive press, water, damp and sunshine.
