The performance of the back-light, for example life time or brightness, is much influenced by the characteristics of the DC-AC inverter for the lamp. So all the parameters of an inverter should be carefully designed so as not to produce too much leakage current from high-voltage output of the inverter. When you design or order the inverter, please make sure that a poor lighting caused by the mismatch of the back-light and the inverter(miss lighting, flicker, etc.) never occur. When you confirm it, the module should be operated in the same condition as it is installed in your instrument. Note (1) Lamp current is measured with current meter for high frequency as shown below. Refer to the block diagram of the back-light unit in the next page for more information. Specified values are for a single lamp. Hot(Red) Cold(White) Hot(Blue) Cold(Black) LCD Module A Inverter (SK1700) Hot(Red) Cold(White) Hot(Blue) Cold(Black) (2) Lamp frequency may produce interference with horizontal synchronous frequency which may cause line flow on the display. Therefore lamp frequency should be detached from the horizontal synchronous frequency and its harmonics as far as possible in order to avoid interference. (3) If an inverter has shutdown function it should keep its output for more than 1 second even if the lamp connector open. Otherwise the lamps may not to be turned on. (4) Because the inverter uses high voltage, please disconnect it from the power before assembling or disassembling. Doc . No PI004_LTM170EU-L11 Page 11/24 4.

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

General Precautions 8.1 Handling (a) When the module is assembled, it should be attached to the system firmly using all mounting holes. Be careful not to twist or bend the modules. (b) Because the inverter use high voltage, it should be disconnected from power before it is assembled or disassembled. (c) Refrain from strong mechanical shock and /or any force to the module. In addition to damage, this may cause improper operation or damage to the module and CCFT back-light. (d) Note that polarizers are very fragile and could be easily damaged. Do not press or scratch the surface using the harder than a HB pencil lead. (e) Wipe off water droplets or oil immediately. If you leave the droplets for a long time, staining and discoloration may occur. (f) If the surface of the polarizer is dirty, clean it using some absorbent cotton or soft cloth. (g) The desirable cleaners are water, IPA(Isopropyl Alcohol) or Hexane. Do not use Ketone type materials(ex. Acetone), Ethyl alcohol, Toluene, Ethyl acid or Methyl chloride. It might permanent damage to the polarizer due to chemical reaction. (h) 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, legs or clothes, it must be washed away thoroughly with soap. (i) Protect the module from static which may cause damage to the CMOS Gate Array IC. (j) Use finger-stalls with soft gloves in order to keep display clean during the incoming inspection and assembly process. (k) Do not disassemble the module. (l) Do not pull or fold the lamp wire. (m) Do not adjust the variable resistor located on the module. (n) Protection film for polarizer on the module should be slowly peeled off just before use so that the electrostatic charge can be minimized. (o) Pins of I/F connector should not be touched directly with bare hands. Doc .

It is highly recommended to store the module with temperature from 0 to 35 ℃ and relative humidity of less than 70%. (b) Do not store the TFT-LCD module in direct sunlight. (c) The module should be stored in a dark place. It is prohibited to apply sunlight or fluorescent light in storage. 8.3 Operation (a) Do not connect or disconnect the module in the "Power On" condition. (b) Power supply should always be turned on/off by 6.3 "Power on/off sequence" (c) Module has high frequency circuits. Sufficient suppression to the electromagnetic interference should be done by system manufacturers. Grounding and shielding methods may be important to minimize the interference. (d) The cable between the back-light connector and its inverter power supply should be connected directly with a minimized length. A longer cable between the back-light and the inverter may cause lower luminance of lamp(CCFT) and may require higher startup voltage(Vs). 8.4 Others (a) Ultra-violet ray filter is necessary for outdoor operation. (b) Avoid condensation of water which may result in improper operation or disconnection of electrode. (c) Do not exceed the absolute maximum rating value. ( supply voltage variation, input voltage variation, variation in part contents and environmental temperature, and so on) Otherwise the module may be damaged. (d) If the module keeps displaying the same pattern for a long period of time, the image may be "sticked" to the screen. (e) This module has its circuitry PCB's on the rear side and should be handled carefully in order not to be stressed. Doc . No PI004_LTM170EU-L11 Page 24/24
