OUTLINE 1.1 STRUCTURE AND PRINCIPLE Color LCD module NL2432HC22-40J 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 controller, 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 * PDAs 1.3 FEATURES * * * * * * Adoption of SR-NLT (Super-Reflective Natural Light TFT) (Transflective type) Backlight attached High luminance High contrast Including LCD controller and power supply 6-bit digital RGB signals DATA SHEET DOD-PP-0129 (3rd edition) 4 NL2432HC22-40J 2.

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 3,920m/s2 and to be not greater 2.5ms) 6.3 ATTENTIONS ! 6.3.1 Handling of the product Take hold of both ends without touching the FPC when the product (LCD module) is picked up from the tray. Do not hook nor pull the FPC 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 product must be installed and/or handled without undue stress such as bends or twist. Bends, twist or undue stress to any portion may cause display failures. And also do not put heavy or hard materials on the product. Do not hit or rub the surface of panel with hard materials, because it is easily scratched. (Polarizer pencil-hardness: 3H) When cleaning the panel surface, wipe it with a soft dry cloth. Do not push nor pull the FPC while the product is working. Do not fold the FPC. When the FPC is folded, pattern disconnection may be caused. In case of bending FPC, the minimum curvature (R) must be more than 1.0 mm. When installing the product, do not contact a conductor such as a metal to the FPC excluding the terminal area. There is a risk of short circuit which is caused by breakage of insulation layer of the FPC. When installing the product, apply the waterproof design to avoid going of water into the product. DATA SHEET DOD-PP-0129 (3rd edition) 25 NL2432HC22-40J 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. Circuits 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. Do not display the fixed pattern for a long time because it may cause image sticking. Optical characteristics may be changed depending on input signal timings. 6.3.4 Other All GND terminals should be used without any non-connected lines. Do not disassemble the product. Pack the product with original shipping package, in order to avoid any damages during transportation, when returning the product to NEC. DATA SHEET DOD-PP-0129 (3rd edition) 26 NL2432HC22-40J 7.
