Note (3) The lamp frequency may generate interference with horizontal synchronous frequency from the display, and this may cause line flow on the display. In order to avoid interference, the lamp frequency should be detached from the horizontal synchronous frequency and its harmonics as far as possible. Note (4) PL = IL xVL Note (5) The lifetime of lamp is defined as the time when it continues to operate under the conditions at Ta = 25 2 oC and IL = 6.0mARMS until one of the following events occurs: (a) When the brightness becomes 50% of its original value.
www..com
(b) When the effective ignition length becomes 80% of its original value. (Effective ignition length is defined as an area that the brightness is less than 70% compared to the center point.)
Note (6) The waveform of the voltage output of inverter must be area-symmetric and the design of the inverter must have specifications for the modularized lamp. The performance of the Backlight, such as lifetime or brightness, is greatly influenced by the characteristics of the DC-AC inverter for the lamp. All the parameters of an inverter should be carefully designed to avoid generating too much current leakage from high voltage output of the inverter. When designing or ordering the inverter please make sure that a poor lighting caused by the mismatch of the Backlight and the inverter (miss-lighting, flicker, etc.) never occurs. If the above situation is confirmed, the module should be operated in the same manners when it is installed in your instrument. The output of the inverter must have symmetrical (negative and positive) voltage waveform and symmetrical current waveform.(Unsymmetrical ratio is less than 10%) Please do not use the inverter, which has unsymmetrical voltage and unsymmetrical current and spike wave. Lamp frequency may produce interface with horizontal synchronous frequency and as a result this may cause beat on the display. Therefore lamp frequency shall be as away possible from the horizontal synchronous frequency and from its harmonics in order to prevent interference. Requirements for a system inverter design, which is intended to have a better display performance, a better power efficiency and a more reliable lamp. It shall help increase the lamp lifetime and reduce its leakage current. a. The asymmetry rate of the inverter waveform should be 10% below; b. The distortion rate of the waveform should be within 2 10%; c. The ideal sine wave form shall be symmetric in positive and negative polarities.

PWM frequency does so that the frequency that is not able to divide the fixed number time, fixed number to lamp drive frequency is selected. (It is due to resonance noise occurrence prevention. ) Even the frequency that is using it for LCD avoids selecting it.

Note (2) When the interface signal is invalid, be sure to pull down the power supply of LCD Vcc to 0 V. Note (3) The Backlight inverter power must be turned on after the power supply for the logic and the interface signal is valid. The Backlight inverter 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 had better to follow t7 5 msec

8. PRECAUTIONS
8.1 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.
www..com
(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 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.
8.2 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 C. For example, the response time will become slowly, and the starting voltage of lamp will be higher than the room temperature.
8.3 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 inverter. Do not disassemble the module or insert anything into the Backlight unit.
