Note (2) If the PWM control duty ratio is less than 10%, there is some possibility that acoustic noise or

Note (1) Please follow the power on/off sequence described above. Otherwise, the LCD module might be

damaged.

Note (2) Please avoid floating state of interface signal at invalid period. When the interface signal is invalid, be

sure to pull down the power supply of LCD VCCS to 0 V.

Note (3) The backlight must be turned on after the power supply for the logic and the interface signal is valid.

The backlight must be turned off before the power supply for the logic and the interface signal is invalid.

Note (4) Please follow the LED converter power sequence as above. If the customer could not follow, it might

cause backlight flash issue during display ON/OFF or damage the LED backlight controller

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.

9. PRECAUTIONS

9.1 HANDLING PRECAUTIONS

(1) The module should be assembled into the system firmly by using every mounting hole. Be careful not

to twist or bend the module.

(2) While assembling or installing modules, it can only be in the clean area. The dust and oil may cause

electrical short or damage the polarizer.

(3) Use fingerstalls or soft gloves in order to keep display clean during the incoming inspection and

assembly process.

(4) Do not press or scratch the surface harder than a HB pencil lead on the panel because the polarizer is

very soft and easily scratched.

(5) If the surface of the polarizer is dirty, please clean it by some absorbent cotton or soft cloth. Do not use

Ketone type materials (ex. Acetone), Ethyl alcohol, Toluene, Ethyl acid or Methyl chloride. It might

Approval

permanently damage the polarizer due to chemical reaction.

(6) Wipe off water droplets or oil immediately. Staining and discoloration may occur if they left on panel for

a long time.

(7) If the liquid crystal material leaks from the panel, it should be kept away from the eyes or mouth. In

case of contacting with hands, legs or clothes, it must be washed away thoroughly with soap.

(8) Protect the module from static electricity, it may cause damage to the C-MOS Gate Array IC.

(9) Do not disassemble the module.

(10) Do not pull or fold the LED wire.

(11) Pins of I/F connector should not be touched directly with bare hands.

9.2 STORAGE PRECAUTIONS

(1) High temperature or humidity may reduce the performance of module. Please store LCD module within

the specified storage conditions.

(2) It is dangerous that moisture come into or contacted the LCD module, because the moisture may

damage LCD module when it is operating.

(3) It may reduce the display quality if the ambient temperature is lower than 10 ºC. For example, the

response time will become slowly, and the starting voltage of LED will be higher than the room

temperature.

9.3 OPERATION PRECAUTIONS

(1) Do not pull the I/F connector in or out while the module is operating.

(2) Always follow the correct power on/off sequence when LCD module is connecting and operating. This

can prevent the CMOS LSI chips from damage during latch-up.

(3) The startup voltage of Backlight is approximately 1000 Volts. It may cause electrical shock while

assembling with converter. Do not disassemble the module or insert anything into the Backlight unit.
