Note (1) The supply voltage of the external system for the module input should be the same as the definition
of Vcc.
Note (2) When the backlight turns on before the LCD operation of the LCD turns off, the display may
momentarily become abnormal screen.
Note (3) In case of VCC = off level, please keep the level of input signals on the low or keep a high
impedance.
Note (4) T4 should be measured after the module has been fully discharged between power off and on
period.
Note (5) Interface signal shall not be kept at high impedance when the power is on.

Note (6) CMO wonϗt take any responsibility for the products which are damaged by the customers not
following the Power Sequence.
Note (7) There might be slight electronic noise when LCD is turned off (even backlight unit is also off). To
avoid this symptom, we suggest "Vcc falling timing" to follow "t6 spec".

Note (5) Measurement Setup:
The LCD module should be stabilized at 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.

8. PRECAUTIONS
8.1 ASSEMBLY AND HANDLING PRECAUTIONS
(1) Do not apply rough force such as bending or twisting to the module during assembly.
(2) To assemble or install module into user’s system can be only in clean working areas. The dust and oil
may cause electrical short or worsen the polarizer.
(3) It’s not permitted to have pressure or impulse on the module because the LCD panel and Backlight will
be damaged.
(4) Always follow the correct power sequence when LCD module is connecting and operating. This can
prevent damage to the CMOS LSI chips during latch-up.
(5) Do not pull the I/F connector in or out while the module is operating.
(6) Do not disassemble the module.
(7) Use a soft dry cloth without chemicals for cleaning, because the surface of polarizer is very soft and
easily scratched.
(8) It is dangerous that moisture come into or contacted the LCD module, because moisture may damage
LCD module when it is operating.
(9) High temperature or humidity may reduce the performance of module. Please store LCD module within
the specified storage conditions.
(10) When ambient temperature is lower than 10ºC may reduce the display quality. For example, the
response time will become slowly.
8.2 SAFETY PRECAUTIONS
(1) If the liquid crystal material leaks from the panel, it should be kept away from the eyes or mouth. In
case of contact with hands, skin or clothes, it has to be washed away thoroughly with soap.
(2) After the module’s end of life, it is not harmful in case of normal operation and storage.
