OUTLINE 1.1 STRUCTURE AND PRINCIPLE Color LCD module NL6448BC33-64E is composed of the amorphous silicon thin film transistor liquid crystal display (a-Si TFT LCD) panel structure with driver LSIs for driving the TFT (Thin Film Transistor) array and a backlight. The a-Si TFT LCD panel structure is injected liquid crystal material into a narrow gap between the TFT array glass substrate and a color-filter glass substrate. Color (Red, Green, Blue) data signals from a host system (e.g. signal generator, etc.) are modulated into best form for active matrix system by a signal processing circuit, and sent to the driver LSIs which drive the individual TFT arrays. The TFT array as an electro-optical switch regulates the amount of transmitted light from the backlight assembly, when it is controlled by data signals. Color images are created by regulating the amount of transmitted light through the TFT array of red, green and blue dots. 1.2 APPLICATION * For industrial use 1.3 FEATURES * * * * * * * * * * High luminance Wide viewing angle High contrast 6-bit digital RGB signals DE (Data enable) function Reversible-scan direction Edge light type (without inverter) Replaceable lamp for backlight Acquisition product for UL60950-1/CSA C22.2 No.60950-1-03 (File number: E170632) Compliance with the European RoHS directive (2002/95/EC) DATA SHEET DOD-PP-0163 (1st edition) 4 NL6448BC33-64E 2.

Note2: The lamp voltage cycle between lamps should be kept on a same phase. "VS" and "VBLH" are the voltage value between low voltage side (Cold) and high voltage side (Hot). Note3: The asymmetric ratio of working waveform for lamps (Power supply voltage peak ratio, power supply current peak ratio and waveform space ratio) should be less than 5 % (See the following figure.). If the waveform is asymmetric, DC (Direct current) element apply into the lamp. In this case, a lamp lifetime may be shortened, because a distribution of a lamp enclosure substance inclines toward one side between low voltage terminal (Cold terminal) and high voltage terminal (Hot terminal). When designing the inverter, evaluate asymmetric of lamp working waveform sufficiently. Pa Sa 0 Sb Pb |Pa - Pb| Pb x 100 5% |Sa - Sb| Sb x 100 5% Pa: Supply voltage/current peak for positive, Pb: Supply voltage/current peak for negative Sa: Waveform space for positive part, Sb: Waveform space for negative part. Note4: This product consists of 2 lamps. 2 lamps are contained in the 1 lamp holder, and both lamps are connected to 1 low voltage cable. Recommended lamp current is 5.0mArms typical for each lamp, and sum of 2 lamps is 10mArms typical. The lamp current should be measured by high-frequency current meter at the low voltage terminal. Note5: The inverter should be designed so that the lamp starting voltage can be maintained for more than 1 second. Otherwise the lamp may not be turned on. Note6: In case "FO" is not the recommended value, beat noise may display on the screen, because of interference between "FO" and "1/th". Recommended value of "FO" is as following. FO = 1 1 x (2n-1) x th 4 th: Horizontal cycle (See "4.9.2 Timing characteristics".) n : Natural number (1, 2, 3 ) Note7: Method of lamp cable installation may invite fluctuation of lamp current and voltage or asymmetric of lamp working waveform. When designing method of lamp cable installation, evaluate the fluctuation of lamp current, voltage and working waveform sufficiently. DATA SHEET DOD-PP-0163 (1st edition) 9 NL6448BC33-64E Note8: In case of Inverter with Ballast condenser, "VS" is the voltage lebel between Ballast condenser and Connector (Refer to the below "Example of measurement"). "VS" should be designed to be more than minimum "VS". Otherwise the lamp may not be turned on because the lamp starting voltage is less than minimum "VS". Example of measurement Probe capacity: 3pF (Tektronix, inc.: P6015A) Ballast condenser (Lamp side) VS High voltage probe Connector Transformer Inverter Probe capacity DATA SHEET DOD-PP-0163 (1st edition) 10 NL6448BC33-64E 4.3.3 Power supply voltage ripple This product works, even if the ripple voltage levels are beyond the permissible values as following the table, but there might be noise on the display image. Ripple voltage Note1 (Measure at input terminal of power supply) Unit 3.3V 100 mVp-p 5.0V 100 mVp-p Power supply voltage VCC Note1: The permissible ripple voltage includes spike noise. 4.3.4 Fuse Fuse Parameter VCC Rating Type Supplier FCC16202AB KAMAYA ELECTRIC CO., LTD. Fusing current Remarks 4.0A Note1 2.0A 32V Note1: The power supply capacity should be more than the fusing current. If it is less than the fusing current, the fuse may not blow in a short time, and then nasty smell, smoke and so on may occur.

PRECAUTIONS 6.1 MEANING OF CAUTION SIGNS The following caution signs have very important meaning. Be sure to read "6.2 CAUTIONS" and "6.3 ATTENTIONS", after understanding these contents! ! This sign has the meaning that customer will be injured by himself or the product will sustain a damage, if customer has wrong operations. This sign has the meaning that customer will get an electrical shock, if customer has wrong operations. This sign has the meaning that customer will be injured by himself, if customer has wrong operations. 6.2 CAUTIONS Do not touch the working backlight. There is a danger of an electric shock. Do not touch the working backlight. There is a danger of burn injury. Do not shock and press the LCD panel and the backlight! There is a danger of breaking, because they are made of glass. (Shock: To be not greater 539m/s2 and to be not greater 11ms, Pressure: To be not greater 19.6 N (16mm jig)) 6.3 ATTENTIONS ! 6.3.1 Handling of the product Take hold of both ends without touching the circuit board when the product (LCD module) is picked up from inner packing box to avoid broken down or misadjustment, because of stress to mounting parts on the circuit board. Do not hook nor pull cables such as lamp cable, and so on, in order to avoid any damage. When the product is put on the table temporarily, display surface must be placed downward. When handling the product, take the measures of electrostatic discharge with such as earth band, ionic shower and so on, because the product may be damaged by electrostatic. The torque for product mounting screws must never exceed 0.294Nm. Higher torque might result in distortion of the bezel. The product must be installed using mounting holes without undue stress such as bends or twist (See outline drawings). And do not add undue stress to any portion (such as bezel flat area). Bends or twist described above and undue stress to any portion may cause display mura. Do not press or rub on the sensitive product surface. When cleaning the product surface, use of the cloth with ethanolic liquid such as screen cleaner for LCD is recommended. Do not push nor pull the interface connectors while the product is working. Do not bend or unbend the lamp cable at the near part of the lamp holding rubber, to avoid the damage for high voltage side of the lamp. DATA SHEET DOD-PP-0163 (1st edition) 26 NL6448BC33-64E Properly connect the plug (backlight side) to adaptable socket (inverter side) without incomplete connection. After connecting, be careful not to hook the lamp cables because incomplete connection may occur by hooking the lamp cables. This incomplete connection may cause abnormal operation of high voltage circuit. If the lamp cable is attached on the metal part of the product directly, high frequency leak current to the metal part may occur, then the brightness may decrease or the lamp may not be turned on. When not connecting FG of the LCD module to the customer's equipment ground, inverter noise may create video noise on the LCD screen. When handling the product, use of an original protection sheet on the product surface (polarizer) is recommended for protection of product surface. Adhesive type protection sheet may change color or characteristics of the polarizer. Usually liquid crystals don't leak through the breakage of glasses because of the surface tension of thin layer and the construction of LCD panel. But, if you contact with liquid crystal for the worst, please wash it out with soap. 6.3.2 Environment Do not operate or store in high temperature, high humidity, dewdrop atmosphere or corrosive gases. Keep the product in packing box with antistatic pouch in room temperature to avoid dusts and sunlight, when storing the product. In order to prevent dew condensation occurring by temperature difference, the product packing box should be opened after enough time being left under the environment of an unpacking room. Evaluate the leaving time sufficiently because a situation of dew condensation occurring is changed by the environmental temperature and humidity. (Recommended leaving time: 6 hours or more with packing state) Do not operate in high magnetic field. Circuit boards may be broken down by it. This product is not designed as radiation hardened. 6.3.3 Characteristics The following items are neither defects nor failures. Response time, luminance and color may be changed by ambient temperature. Display mura, flicker, vertical seam or small spot may be observed depending on display patterns. Optical characteristics (e.g. luminance, display uniformity, etc.) gradually is going to change depending on operating time, and especially low temperature, because the LCD has cold cathode fluorescent lamps. Do not display the fixed pattern for a long time because it may cause image sticking. Use a screen saver, if the fixed pattern is displayed on the screen. The display color may be changed depending on viewing angle because of the use of condenser sheet in the backlight. Optical characteristics may be changed depending on input signal timings. The interference noise between input signal frequency for this product's signal processing board and luminance control frequency of the inverter may appear on a display. Set up luminance control frequency of the inverter so that the interference noise does not appear. After the product is stored under condition of low temperature or dark place for a long time, the cold cathode fluorescent lamp may not be turned on under the same condition because of the general characteristic of cold cathode fluorescent lamp. In addition, when Luminance control ratio is low in pulse width modulation method inverter, the lamp may not be turned on. In this case, power should be supplied again. DATA SHEET DOD-PP-0163 (1st edition) 27 NL6448BC33-64E 6.3.4 Other All GND and VCC terminals should be used without any non-connected lines. Do not disassemble a product or adjust variable resistors. See "REPLACEMENT MANUAL FOR LAMP HOLDER SET", when replacing backlight lamps. Pay attention not to insert foreign materials inside of the product, when using tapping screws. Pack the product with original shipping package, in order to avoid any damages during transportation, when returning the product to NEC for repair and so on.
