Notes 1) Larger IL causes the shorter life of a CCFL. 2) Frequency of power supply for a CCFL may cause interference with HSYNC frequency and causes beat or flicker on the display. Therefore, lamp frequency shall be as different as possibl e from HSYNC frequency in order to avoid the interference. 3) To be measured at GND terminal side 4) Starting Lamp Votage should be kept 1 sec at least. 5) The inverter should be built-in a safety circuit which detects over current, over voltage and distorted wave form of lamp current.

10. PRECAUTION
Please pay attention to the followings when you use this TFT-LCD Module with Back-light unit. 10.1 Precaution to handling and mounting (1) You should consider the mouting structure so that uneven force (ex. twisted stress) is not applied to the module. (2) To improve the strength of module against the mechanical shock the space between the module and the case should be less than 1.0mm. (3)Protection material in front of LCD's screen surface is recommended to protect a polarizer, LCD-glass and metal bezel. Please be note that the protection material should not touch them directry. (4) Acetic acid type and chloline type materials for the cover case are not desiable because the former generate corrosive gas of attacking the polarizer at high temperature and the latter causes circuit break by electro-chemical reaction. (5)Do not touch, push or rub the exposed polarizers with glass, tweezers or anything harder than HB pencil lead. And please do not rub by dustclothes with chemical treatment. Do not touch the surface of polarizer with bare hand or greasy close. (Some cosmetics are detrimental to the polarizer.) (6) When the surface becomes dusty,please wipe gently with absorbent cotton or other soft materials chamois soaked Normal-Hexane. Normal-Hexane is recommended for clearning the adhesives used to attach front /rear polarizers. Do not use acetone, toluen and alcohol because they cause chemical damage to the polarizer. (7) Wipe off saliva or water drops as soon as possible. Their long time contact with polarizer cuses deformations and color fading. (8)The module should never be opened or modified. It may cause not to operate properly. (9) Metallic bezel of a module should not be handled with bare hand or dirty gloves. Otherwise, color of a metallic frame may become dirty during its storage. It is recommended to use clean soft gloves and clean finger stalls when a module is handled at incoming inspection process and production (assembly) process. (10)When you adopt a metallic shield board on backside of TFT-LCD Module, it should not be too close to TFT-LCD Module. (11) Do not pull or do not fold the CCFL cable.

10.2 Precaution to operation (1) You should adopt radiation structure to satisfy the temperature specification. (2) Optical response time, luminance and chromaticity depend on the temperature of a TFT-LCD module. (At lower temperature it becomes longer.) (3)Response time and saturation time of CCFL luminance become longer at lower temperature operation. (4) Sudden temperature change may cause dew on and/or in the a module. Dew males damage to a polarizer and/or electrical contacting portion. Dew causes fading of displayed quality. (5) Fixed patterns displayed on a module for a long time may cause after-image. It will be recovered soon. (6) Please connect the Back-light connector to the inverter circuit directly. The long cable between CCFL and the inverter may cause the brightness drop of CCFL and may cause the rise of starting lamp voltage(Vs). (8) The module should not be connected or removed while a main system works. (9) Inserting or pulling I/F connectors causes any truble when power supply and signal datas are on-state.I/F connectors should be inserted and pulled after power supply and signal datas are turned off. 10.3 Electrostatic discharge control (1) Since a module consists of a TFT cell and electronic circuits with CMOS-ICs, which are very weak to electrostatic discharge, persons who are handling a module should be grounded through adequate methods such as a list band. I/F connector pins should not be touched directly with bare hands. (2) Protection film for a polarizer on a module should be slowly peeled off so that the electrostatic charge can be minimized. 10.4 Precaution to strong light exposure A module should not be exposed under strong light. Otherwise, characteristics of a polarizer and color filter in a module may be degraded.

10.5 Precaution to storage When TFT-LCD Modules are stored for a long time, following precautions should be taken care of: (1) Modules should be stored in a dark place. It is prohibited to apply sunlight or fluorescent light during storage. Modules should be stored at 0 to 35C at normal humidity (60%RH or less). (2) The surface of polarizers should not come in contact with any other object. It is recommended that modules should be stored in the Hitachi's shipping box. 10.6 Precaution to handle protective film (1)When the protective film is peeled off, static electricity is generated between the film and the polarizer. This film should be peeled off slowly and carefully by people who are electrically grounded and with well ion-blown equipment or in such a condition, etc. (2)The protective film is attached to the polarizer with a small amount of glue. If some stress is applied to rub the protective film against the polarizer during the time you peel off the film, the glue is apt to remain more on the polarizer. So please carefully peel off the protective film without rubbing it against the polarizer. (3)When the module with protective film attached is stored for long time, sometimes there remains a very small amount of glue, still on the polarizer after the protective film is peeled off. Please refrain from storing the module at the high temperature and high humidity for glue is apt to remain in these condition. (4)The glue may be taken for the modules failure, but you can remove the glue easily. When the glue remains on the polarizer surface or its vestige is recognized, please wipe them off with absorbent cotton waste or other soft material like chamois soaked with Normal-Hexane. 10.7 Safety (1) If module is broken, be careful to handle not to injure. (TFT-LCD and Lamp are made of glass.) Please wash hands sufficiently when you touch the liquid crystal coming out from broken LCDs. (2)As Back-light unit has high voltage circuit internal, do not open the case and do not insert foreign materials in the case. (3)The CCFL inverter should be designed to include the function of output shutdown in case the output overcurrent happen due to any backlight trouble. The shutdown function should be assured to work in abnormal condition at the actual systems.
