5. Electrical Specifications 5-1. Electrical Characteristics
The LB040Q02 requires two power inputs. One is employed to power the LCD electronics and to drive the TFT array and liquid crystal. The second input which powers the CCFL, is typically generated by an inverter. The inverter is an external unit to the LCD. Table 2. ELECTRICAL CHARACTERISTICS

Power Consumption Life Time
Note) The design of the inverter must have specifications for the lamp in LCD Assembly. 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 your instrument. * 1. VCC=3.3V, 25C, fV (frame frequency) = 60Hz condition, whereas mosaic pattern(Typ),full black pattern(Max) is displayed. [LDO output voltage(3.3V) is applied.] * 2. This frequency range means the range to keep within 10% change of electrical and optical characteristics. * 3. This frequency range means not affecting to lamp life and reliability characteristics. (The lamp frequency should be selected as different as possible from display horizontal synchronous signal (Including harmonic frequency of this scanning frequency) to avoid "Beat" interference which may be observed on the screen as horizontal stripes like moving wave.

Product Specification
This phenomenon is caused by interference between lamp (CCFL) lighting frequency and LCD horizontal synchronous signal.) * 4. The "MAX" of "Kick-Off Voltage" means the minimum voltage for inverter to turn on the CCFL . normally in the LCD module. However this isn't the values that we can assure stability of starting lamp on condition that the module is installed in your set. It should be careful that "Kick-Off Voltage" is changed by an increase of stray capacitance in your set, inverter method, value of ballast capacitor in your inverter and so on. Especially, the value of "Kick-Off Voltage" is higher in low temperature condition than in normal temperature condition, because impedance of CCFL is increased. The voltage above VS should be applied to the lamps for more than 1 second for start-up. Otherwise, the lamps may not be turned on. The used lamp current is the lamp typical current. * 5. The time needed to achieve not less than 95%brightness of the center part of lamp. The brightness of the lamp after being lighted for 5 minutes is defined as 100%. * 6. "Life time" is defined as the time that the lamp brightness decreases to 50% from original brightness at IBL=TYP; continuous lighting, Ta=25 . 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 as follows. It shall help increase the lamp lifetime and reduce leakage current. Inverter should be designed to be subject to the conditions below 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.
* Asymmetry rate: Ip
( I p - I -p |) / Irms * 100%
I -p *Distortion rate:
I p (or I -p) / Irms
C. There should not be any spikes in the waveform. D. Lamp current should not exceed the "MAX" value under the "Operating Temperature" (it is prohibited to exceed the "MAX." value even if it is operated in the guaranteed temperature). When lamp current exceed the maximum value for a long time, it may cause a smoking and Ignition. Therefore, it is recommended that the inverter have the current limited circuit that is used as a protection circuit and/or the lamp current-controlled inverter. Do not attaches 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.
5-2. Interface Connections
This LCD employs Two interface connections, a 40 pin connector is used for the module electronics interface and the other connectors is used for the integral backlight system. The electronics interface connector is a model F100-S40B-C25 manufactured by UJU

11. PRECAUTIONS
Please pay attention to the following when you use this TFT LCD module.
11-1. 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 a 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 deteriorate 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. (10) The metal case of a module should be contacted to electrical ground of your system.
11-2. 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.

11-3. 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.
11-4. PRECAUTIONS FOR STRONG LIGHT EXPOSURE
Strong light exposure causes degradation of polarizer and color filter.
11-5. 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 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.
11-6. HANDLING PRECAUTIONS FOR PROTECTION FILM
(1) 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 ion-blown equipment or in such a condition, etc. (2) The protection film is attached to the polarizer with a small amount of glue. If some stress is applied to rub the protection film against the polarizer during the time you peel off the film, the glue is apt to remain on the polarizer. Please carefully peel off the protection film without rubbing it against the polarizer. (3) 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 polarizer after the protection film is peeled off. (4) 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.
