3.2 BACK-LIGHT UNIT
Approval
The backlight system is an edge-lighting type with a single CCFT ( Cold Cathode Fluorescent Tube ). The characteristics of a single lamp are shown in the following table. Ta= 25 2 C Item Lamp Current Lamp Voltage Frequency Power Consumption Operating Life Time Startup Voltage Symbol IL VL fL PL Hr VS Min. 3.0 45 15,000 Typ. 6.5 655 4.6 1500 Vrms 0C, (5) Max. 7.0 7 5.0 1250 Unit mArms Vrms KHz W Hour Vrms Note (1) IL = 6.5mA (2) (3) IL = 6.5mA (4) 25C, (5)
Note) The waveform of the inverter output voltage must be area symmetric and the design of the inverter must have specifications for the modularized lamp. The performance of the backlight, 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 backlight 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 a high frequency current meter as shown below.

(2) Lamp frequency may produce interference with horizontal synchronous frequency and this 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) Refer to IL xVL to calculate. (4) Life time (Hr) of a lamp can be defined as the time in which it continues to operate under the condition Ta= 25 2 C and IL = 6.0 mArms until one of the following event occurs. 1. When the brightness becomes 50% or lower than the original. 2. When the Effective ignition length becomes 80% or lower than the original value. (Effective ignition length is defined as an area that has less than 70% brightness compared to the brightness in the center point.) 3. CCFL only (5) The inverter open voltage - this voltage should be measured after ballast capacitor- have to be larger than the lamp startup voltage, otherwise backlight may has blinking for a moment after turns on or not be turned on. If an inverter has shutdown function it should keep its open voltage for longer than 1 second even if lamp connector open. Samsung Secret

Non-uniformity can be occurred due to mercury distribution under 20% duty ratio. 4. Lamp life time reduction . Lamp life time can be shortened under the usage of low temperature or lower duty ratio for a long time.

Power ON/OFF Sequence
T1 : Vdd rising time from 10% to 90% T2 : The time from Vdd to valid data at power ON. T3 : The time from valid data off to Vdd off at power Off. T4 : Vdd off time for Windows restart T5 : The time from valid data to B/L enable at power ON. T6 : The time from valid data off to B/L disable at power Off.
NOTE. (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 white. (3) In case of VDD = off level, please keep the level of input signals on the 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 shall not be kept at high impedance when the power is on.

10. GENERAL PRECAUTIONS
1. Handling
www..com
Approval
(a) When the module is assembled, It should be attached to the system firmly using every mounting holes. Be careful not to twist and bend the modules. (b) 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. (c) Note that polarizers are very fragile and could be easily damaged. Do not press or scratch the surface harder than a HB pencil lead. (d) Wipe off water droplets or oil immediately. If you leave the droplets for a long time, Staining and discoloration may occur. (e) If the surface of the polarizer is dirty, clean it using some absorbent cotton or soft cloth. (f) The desirable cleaners are water, IPA (Isoprophyl 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. (g) 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. (h) Protect the module from static , it may cause damage to the C-MOS Gate Array IC. (i) Use fingerstalls with soft gloves in order to keep display clean during the incoming inspection and assembly process. (j) Do not disassemble the module. (k) Do not pull or fold the lamp wire. (l) Do not adjust the variable resistor which is located on the back side. (m) Protection film for polarizer on the module shall be slowly peeled off just before use so that the electrostatic charge can be minimized. (n) Pins of I/F connector shall not be touched directly with bare hands.

2. STORAGE
www..com
Approval
(a) Do not leave the module in high temperature, and high humidity for a long time. It is highly recommended to store the module with temperature from 0 to 35 C and relative humidity of less than 70%. (b) Do not store the TFT-LCD module in direct sunlight. (c) The module shall be stored in a dark place. It is prohibited to apply sunlight or fluorescent light during the store. 3. OPERATION (a) Do not connect,disconnect the module in the " Power On" condition. (b) Power supply should always be turned on/off by following item 6.3 " Power on/off sequence ". (c) Module has high frequency circuits. Sufficient suppression to the electromagnetic interference shall 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 shall be a minimized length and be connected directly . The longer cable between the back-light and the inverter may cause lower luminance of lamp(CCFT) and may require higher startup voltage (Vs). (e) The standard limited warranty is only applicable when the module is used for general notebook applications. If used for purposes other than as specified, SEC is not to be held reliable for the defective operations. It is strongly recommended to contact SEC to find out fitness for a particular purpose. 4. OTHERS (a) Ultra-violet ray filter is necessary for outdoor operation. (b) Avoid condensation of water. It may result in improper operation or disconnection of electrode. (c) Do not exceed the absolute maximum rating value. ( the supply voltage variation, input voltage variation, variation in part contents and environmental temperature, so on) Otherwise the module may be damaged. (d) If the module displays the same pattern continuously for a long period of time,it can be the situation when the image "sticks" 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.
