NL2432HC22-41K data sheet dod-pp-0307 (2nd edition) 4 1. outline 1.1 structure and principle color lcd module NL2432HC22-41K is composed of the amorphous silicon thin film transistor liquid crystal display (a-si tft lcd) panel structure wi th driver lsis for driving the tft (thin film transistor) array, touch pa nel (t/p) 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. co lor 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 and touch panel attached ? high luminance ? high contrast ? including lcd controller and power supply ? 6 - bit digital rgb signals ? compliance with the european rohs directive (2002/95/ec) www.datasheet.co.kr datasheet pdf - http://www..net/

(shock: to be not greater 3,920m/s 2 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 temporar ily, 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 any stress such as bends or twist. bends, twist or any 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 touch panel with hard materials, because it is easily scratched. (touch panel pencil-hardness: 3h) when cleaning the t/p 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 co nductor such as a metal to the fpc excluding the terminal area. there is a risk of short circuit whic h 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. www.datasheet.co.kr datasheet pdf - http://www..net/
NL2432HC22-41K data sheet dod-pp-0307 (2nd edition) 27 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 for 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. (r ecommended 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 ne ither 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. touch panel film has polarizing characteristic. a nd the polarizer characteristics differ among products. therefore, when seeing the displays through the other polarizing material (for example polarizing sunglasses), some displays can not be seen and some displays look different color darker because of polarizer characteristic mismatching between touch panel film and the other polarizing material. 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. when installing the product to customer equipment, do not apply any stress to the rear side of the product, fpc, a area, soldering area and mounting area. if not, it may cause display un-uniformity or lcd panel separation or break down of the product. www.datasheet.co.kr datasheet pdf - http://www..net/
