OUTLINE 1.1 STRUCTURE AND PRINCIPLE Color LCD module NL6448BC33-70D 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 board, 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 * * * * * * * * * * * Long life LED backlight type High luminance High contrast Wide viewing angle Wide temperature range 6-bit digital RGB signals DE (Data enable) function Reversible-scan direction Replaceable lamp holder for backlight Acquisition product for UL60950-1/CSA C22.2 No.60950-1-03 (File number: E170632) Compliant with the European RoHS directive (2002/95/EC) DATA SHEET DOD-PP-0955 (1st edition) 4 NL6448BC33-70D 2.

PRECAUTIONS 7.1 MEANING OF CAUTION SIGNS The following caution signs have very important meaning. Be sure to read "7.2 CAUTIONS" and "7.3 ATTENTIONS"! ! This sign has the meaning that a customer will be injured or the product will sustain damage if the customer practices wrong operations. This sign has the meaning that a customer will be injured if the customer practices wrong operations. 7.2 CAUTIONS Do not shock and press the LCD panel and the backlight! There is a danger of breaking, because they are made of glass. (Shock: Equal to or no greater than 539m/s2 and equal to or no greater than 11ms, Pressure: Equal to or no greater than 19.6 N (16mm jig)) 7.3 ATTENTIONS ! 7.3.1 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. 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, wipe it with a soft dry cloth. Do not push or pull the interface connectors while the product is working. 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 by any chance, please wash it away with soap and water. DATA SHEET DOD-PP-0955 (1st edition) 26 NL6448BC33-70D 7.3.2 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 occurred by temperature difference, the product packing box must be opened after enough time being left under the environment of an unpacking room. Evaluate the storage time sufficiently because dew condensation is affected by the environmental temperature and humidity. (Recommended leaving time: 6 hours or more with the original packing state after a customer receives the package) Do not operate in high magnetic field. If not, circuit boards may be broken. This product is not designed as radiation hardened. 7.3.3 Characteristics The following items are neither defects nor failures. Characteristics of the LCD (such as response time, luminance, color uniformity and so on) may be changed depending on ambient temperature. If the product is stored under condition of low temperature for a long time, it may cause display mura. In this case, the product should be operated after enough time being left under condition of operating temperature. Display mura, flickering, vertical streams or tiny spots may be observed depending on display patterns. 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. 7.3.4 Others 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 lamp holder set .
