4 LM9E8. General Description LM9E8TLA is a Color Active Matrix with an integral Cold Cathode Fluorescent Lamp(CCFL) backlight system. The matrix employs asi Thin Film Transistor as the active element. It is a transmissive type display operating in the normally white mode. It has a 9. inch diagonally measured active display area with SXGA resolution (24 vertical by 28 horizontal pixel array) Each pixel is divided into Red, Green and Blue subpixels or dots which are arranged in vertical stripes. Gray scale or the brightness of the subpixel color is determined with a 8bit gray scale signal for each dot, thus, presenting a palette of more than 6,7M colors with AdvancedFRC(Frame Rate Control). It has been designed to apply the interface method that enables low power, high speed, low EMI. FPD Link or compatible must be used as a LVDS(Low Voltage Differential Signaling) chip. It is intended to support applications where thin thickness, wide viewing angle, low power are critical factors and graphic displays are important. In combination with the vertical arrangement of the subpixels, the LM9E8TLA characteristics provide an excellent flat panel display for office automation products such as monitors. FIG.

The performance of the Lamp in LCM, for example life time or brightness, is extremely influenced by the characteristics of the DCAC inverter. So all the parameters of an inverter should be carefully designed so as not to produce too much leakage current from highvoltage 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, TFTLCD Module has a low luminance and the inverter has abnormal action. Because leakage current is occurred between lamp wire and conducting tape.. Specified values are for a single lamp. 2. Operating voltage is measured at 25 2 C. The variance of the voltage is %. 3. The voltage above V S should be applied to the lamps for more than second for startup. (Inverter open voltage must be more than lamp starting voltage.) Otherwise, the lamps may not be turned on. The used lamp current is the lamp typical current. 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. Let s define the brightness of the lamp after being lighted for 5 minutes as %. T S is the time required for the brightness of the center of the lamp to be not less than 95%. 6. The lamp power consumption shown above does not include loss of external inverter. The used lamp current is the lamp typical current. (P BL = V BL x I BL x N Lamp ) 7. The life is determined as the time at which brightness of the lamp is 5% compared to that of initial value at the typical lamp current on condition of continuous operating at 25 2 C. Ver..

8 LM9E8 Note : 8. The output of the inverter must have symmetrical(negative and positive) voltage waveform and symmetrical current waveform (Unsymmetrical ratio is less than %). 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 %. b. The distortion rate of the waveform should be within 2 %. * Inverter output waveform had better be more similar to ideal sine wave. * Asymmetry rate: I p I p I p / I rms x % I p * Distortion rate I p (or I p ) / I rms 9. The inverter which is combined with this LCM, is highly recommended to connect coupling(ballast) condenser at the high voltage output side. When you use the inverter which has not coupling(ballast) condenser, it may cause abnormal lamp lighting because of biased mercury as time goes..in case of edgy type back light with over 4 parallel lamps, input current and voltage wave form should be synchronized Ver..

28 LM9E8 9. PRECAUTIONS Please pay attention to the followings when you use this TFT LCD module. 9. MOUNTING PRECAUTIONS () 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 electrochemical 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 benzene. Normalhexane 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. 92. OPERATING PRECAUTIONS () The spike noise causes the misoperation of circuits. It should be lower than following voltage : V= 2mV(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 not be operated its full characteristics perfectly. (8) A screw which is fastened up the steels should be a machine screw (if not, it causes metal foreign material and deal LCM a fatal blow) (9) Please do not set LCD on its edge. Ver.. Nov, 3, / 29

29 LM9E8 93. 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. 94. PRECAUTIONS FOR STRONG LIGHT EXPOSURE Strong light exposure causes degradation of polarizer and color filter. 95. STORAGE When storing modules as spares for a long time, the following precautions are necessary. () Store them in a dark place. Do not expose the module to sunlight or fluorescent light. Keep the temperature between 5 C and 35 C at normal humidity. (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. 96. HANDLING PRECAUTIONS FOR PROTECTION FILM () 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. Ver..
