Note 3
Note 1: SPI Interface is only to set up the initial code in LCM driver IC register.
Note 2: There had been default initial code stored in LCD driver IC at Sync Mode operation, and if customer
needs to revise the default initial code to change gamma or Vcom voltage, then SPI interface is
needed.
Note 3: Different from Sync mode, there is no default initial code in driver IC in DE mode, so initial code has
to be setup via SPI interface at DE mode.

-Note 1: Definition of Contrast Ratio (CR):
The contrast ratio can be calculated by the following expression.
Contrast Ratio (CR)= L63/L0
L63: Luminance of gray level 63
L0: Luminance of gray level 0
CR=CR (10)
CR(X) is corresponding to the Contrast Ratio of the point X at Figure in Note (5)

(4) Measurement Set-Up:
The LCD module should be stabilized at a given temperature for 20 minutes to avoid abrupt
temperature Change during measuring. In order to stabilize the luminance, the measurement
should be executed after lighting Backlight for 20 minutes in a windless room.

Major defect :
A major defect is a defect that could result in failure or extremely reduction on the usability of
the product for its intended purpose.
Minor defect :
A minor defect is one that does not materially reduce the usability of the product for its
intended purple or is a departure from established standards giving no significant bearing on the
effective use or operation of the unit.
10.2.2 Inspection Conditions
10.2.2.1 The environmental conditions for inspection shall be as follows
- Room Temperature : 25±10°C
- Humidity Temperature : 45±20%RH
10.2.3 The external visual inspection
- The inspection shall be performed by using 40Watts fluorescent lamp for illumination and the
distance between LCD and eyes of the inspector shall be 30cm or more.

11.1.3 Test Method
The method of visual inspection is equal to the appearance standard. Evaluation and assessment
made two hours after return to room temperature (25 ± 5°C). The LCDs subjected to the test
must not have dew condensation.
The test pattern is gray scale and the operating voltage sweep from Vth to Vsat variable.
The non-uniformity and other appearance are checked in LCD.
11.1.4 Result Evaluation Criteria
There should be no change which might affect the practical display function when the display
quality test is conducted under normal operating condition.
11.1.5 Life time
Life time expectancy of LCD Panel is approximately 50,000 hours under the room environment. D
efinition on the termination of life time is deterioration of contrast ratio by one fifth against
initial value.
11.1.6 Basic rule for Reliability test
* Place all the samples under room temperature & humidity for 24 hours after reliability stressing.
* Room environment means 25+/-10°C, 45+/-20%RH
* There should be no condensation during the test.
* One LCD module shall be used for one test item only and once.
11.1.7 Judgment Criteria for reliability test No. 1-2
* Contrast (or Brightness) ratio variation is within 50% of the initial value.
* No abnormal function
* No extreme decay on appearance
11.1.8 Life time

12. PRECAUTIONS
12.1 Operation
Burn-in sometimes happens when the same character was displayed at along time.
Therefore, to prevent Burn-in, it is recommended to set up a Screen-saver function.
12.2 Safety
The liquid crystal in the LCD is poisonous, DO NOT put it in your mouth. If the liquid crystal to
uches your skin or clothes, wash it off immediately using soap and water.
12.3 Handling
a. The LCD module shall be installed flat,
without twisting or bending.
b. COF or FPC has narrow pattern width, so
easily become open circuit by external force.
DO NOT apply pressure to COF or FPC
especially in bending area.
c. To avoid damage in appearance or
malfunction, DO NOT subject the module to
mechanical shock or to excessive force on its
surface.
d. The polarizer attached to the display is very
easy to damage, handle it with care to avoid
scratching.
e. To avoid contamination on the display
surface, DO NOT touch the display surface
with bare hands.
f. Provide a space so that the LCD module
does not come into contact with other
components.

g. To protect the LCD panel from external
pressure, put covering glass (acrylic board or
similar board) to keep appropriate space
between them.
h. Be careful for condensation at sudden
temperature change. Condensation makes
damage to polarizer or electrical contacted
parts. And after fading condensation, smear
or spot will occur.
i. Property of semiconductor devices may be
affected when they are exposed to light
possibly resulting in malfunctioning of the
ICs. To prevent such malfunctioning of the
ICs, your design and mounting layout done
are so that the IC is not exposed to light in
actual use.
j. Strong light exposure causes degradation of
color filter. It may not recover
k. DO NOT contact with water to avoid Metal
corrosion.
l. When it is not in use, the screen must be
turned off or the pattern must be frequently
changed by a screen saver. If it displays the
same pattern for a long period of time,
brightness down/image sticking may develop
due to the LCD structure.
m. Never disassemble LCD product under any
circumstances. If unqualified operators or
users assemble the product after
disassembling it, it may not function or its
operation may be seriously affected.

12.4 Static electricity
Since a module is composed of electronic circuits, it is not strong to electrostatic
discharge.
a.
The LCD module shall be installed flat,
without twisting or bending. Ground
soldering iron tips, tools and testers when
they operate.
b. Ground your body when handling the
products.
c.
DO NOT apply voltage to the input
terminal without applying power supply.
d.
DO NOT apply voltage that exceeds the
absolute maximum rating.
e.
Store the products in an anti-electrostatic
container.
f.
Peel off protect tape, attached to polarizer,
slowly to minimize ESD damage.
12.5 Storage
Store the products in a dark place at +5 ~ +25
degree C, low humidity (50%RH or less).
DO NOT store the products in an atmosphere
containing organic solvents or corrosive gases.
12.6 Cleaning
a. DO NOT wipe the polarizer with dry cloth, as
it might cause scratch.
b. Wipe the polarizer with a soft cloth soaked
with petroleum IPA, other chemical might
damage.
12.7 Waste
When dispose of LCD module, manage it at the
production waste according to the relevant laws
and regulations.
