Life Time
Note : The design of the inverter must have specifications for the lamp in LCD Assembly. The electrical characteristic of inverter is based on High-High Driving type The performance of the Lamp in LCM, for example life time or brightness, is extremely influenced by the characteristics of the DC-AC inverter. 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 unwanted lighting caused by the mismatch of the lamp and the inverter (no lighting, flicker, etc) never occurs. When you confirm it, the LCD Assembly should be operated in the same condition as installed in you instrument. Do not attach a conducting tape to lamp connecting wire. If the lamp wire attach to a conducting tape, TFT-LCD Module has a low luminance and the inverter has abnormal action.Because leakage current is occurred between lamp wire and conducting tape. 1. Specified values are for a Backlight Assembly. 2. Operating voltage is measured at 25 ± 2° The variance of the voltage is ± 10%. C. 3. The voltage above VS should be applied to the lamps for more than 1 second for start-up. (Inverter open voltage must be more than established starting voltage. Otherwise, the lamps may not be turned on. The used lamp current is typical value.

4. 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. 5. The brightness of the lamp after lighted for 5minutes is defined as 100%. TS is the time required for the brightness of the center of the lamp to be not less than 95% at typical current The screen of LCD module may be partially dark by the time the brightness of lamp is stable after turn on. 6. Max of power consumption is measured at initial turn on. Typical of power consumption is measured after 2hrs aging at 25 ± 2° C. 7. The life is determined as the time at which brightness of the lamp is 50% compared to that of initial value at the typical lamp current on condition of continuous operating at 25 ± 2° based on duty 100% C, 8. 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. Requirements for a system inverter design, which is intended to have a better display performance, a better power efficiency and a more reliable lamp, are following. It shall help increase the lamp lifetime and reduce leakage current. a. The asymmetry rate of the inverter waveform should be less than 10%. b. The distortion rate of the waveform should be within 2 10%. * Inverter output waveform had better be more similar to ideal sine wave.

Note : 1. Contrast Ratio(CR) is defined mathematically as : CR (Contrast Ratio) = Maximum CRn (n=1, 2, 3, 4, 5) DCR (Dynamic CR) = Maximum CRn (n=1, 2, 3, 4, 5) Surface Luminance at position n with all white pixels CRn = Surface Luminance at position n with all black pixels n = the Position number(1, 2, 3, 4, 5), For more information, see FIG 2. 2. Surface luminance are determined after the unit has been `ON' and 30min after lighting the backlight in a dark environment at 25± 2° Surface luminance is the luminance value at center C. 1-point across the LCD surface 50cm from the surface with all pixels displaying white. For more information see the FIG. 2. 3. The variation in surface luminance , WHITE is defined as : WHITE(5P) = Maximum(Lon1,Lon2, Lon3, Lon4, Lon5) / Minimum(Lon1,Lon2, Lon3, Lon4, Lon5) Where Lon1 to Lon5 are the luminance with all pixels displaying white at 5 locations . For more information, see the FIG. 2. 4. Response time is the time required for the display to transition from G(N) to G(M) (Rise Time, TrR) and from G(M) to G(N) (Decay Time, TrD).

9. Precautions
Please pay attention to the followings when you use this TFT LCD module.
9-1. Mounting Precautions
(1) You must mount a module using holes arranged in four corners or four sides. (2) You should consider the mounting structure so that uneven force (ex. Twisted stress) is not applied to the module. And the case on which a module is mounted should have sufficient strength so that external force is not transmitted directly to the module. (3) Please attach the surface transparent protective plate to the surface in order to protect the polarizer. Transparent protective plate should have sufficient strength in order to the resist external force. (4) You should adopt radiation structure to satisfy the temperature specification. (5) Acetic acid type and chlorine type materials for the cover case are not desirable because the former generates corrosive gas of attacking the polarizer at high temperature and the latter causes circuit break by electro-chemical reaction. (6) Do not touch, push or rub the exposed polarizers with glass, tweezers or anything harder than HB pencil lead. And please do not rub with dust clothes with chemical treatment. Do not touch the surface of polarizer for bare hand or greasy cloth.(Some cosmetics are detrimental to the polarizer.) (7) When the surface becomes dusty, please wipe gently with absorbent cotton or other soft materials like chamois soaks with petroleum benzine. Normal-hexane is recommended for cleaning the adhesives used to attach front / rear polarizers. Do not use acetone, toluene and alcohol because they cause chemical damage to the polarizer. (8) Wipe off saliva or water drops as soon as possible. Their long time contact with polarizer causes deformations and color fading. (9) Do not open the case because inside circuits do not have sufficient strength.
9-2. Operating Precautions
(1) The spike noise causes the mis-operation of circuits. It should be lower than following voltage : V=± 200mV(Over and under shoot voltage) (2) Response time depends on the temperature.(In lower temperature, it becomes longer.) (3) Brightness depends on the temperature. (In lower temperature, it becomes lower.) And in lower temperature, response time(required time that brightness is stable after turned on) becomes longer. (4) Be careful for condensation at sudden temperature change. Condensation makes damage to polarizer or electrical contacted parts. And after fading condensation, smear or spot will occur. (5) When fixed patterns are displayed for a long time, remnant image is likely to occur. (6) 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 minimized the interference. (7) Please do not give any mechanical and/or acoustical impact to LCM. Otherwise, LCM can't be operated its full characteristics perfectly. (8) A screw which is fastened up the steels should be a machine screw. (if not, it causes metallic foreign material and deal LCM a fatal blow) (9) Please do not set LCD module on its edge.

9-3. Electrostatic Discharge Control
Since a module is composed of electronic circuits, it is not strong to electrostatic discharge. Make certain that treatment persons are connected to ground through wrist band etc. And don't touch interface pin directly.
9-4. Precautions for Strong Light Exposure
Strong light exposure causes degradation of polarizer and color filter.
9-5. Storage
When storing modules as spares for a long time, the following precautions are necessary. (1) Store them in a dark place. Do not expose the module to sunlight or fluorescent light. Keep the temperature between 5° and 35° at normal humidity. C C (2) The polarizer surface should not come in contact with any other object. It is recommended that they be stored in the container in which they were shipped.
9-6. Handling Precautions for Protection Film
(1) The protection film is attached to the bezel with a small masking tape. When the protection film is peeled off, static electricity is generated between the film and polarizer. This should be peeled off slowly and carefully by people who are electrically grounded and with well ionblown equipment or in such a condition, etc. (2) When the module with protection film attached is stored for a long time, sometimes there remains a very small amount of glue still on the bezel after the protection film is peeled off. (3) You can remove the glue easily. When the glue remains on the bezel surface or its vestige is recognized, please wipe them off with absorbent cotton waste or other soft material like chamois soaked with normalhexane.
