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 Vcc to 0 V.

Note (3) The Backlight converter power must be turned on after the power supply for the logic and the

interface signal is valid. The Backlight converter power must be turned off before the power supply

for the logic and the interface signal is invalid.

Note (4) Sometimes some slight noise shows when LCD is turned off (even backlight is already off). To

avoid this phenomenon, we suggest that the Vcc falling time is better to follow 50us Љ t7 Љ

9. PRECAUTIONS

9.1 ASSEMBLY AND 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

www.panelook.com

Issued Date: Apr, 22, 2009

Model No.: N121IB - L05

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 lamp wire.

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

9.2 SAFETY PRECAUTIONS

(1) 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.

(2) 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.

(3) After the module’s end of life, it is not harmful in case of normal operation and storage.

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.

9.4 OTHER PRECAUTIONS

(1) When fixed patterns are displayed for a long time, remnant image is likely to occur.
