data sheet en0418ej1v0ds00 2 NL10276AC30-03A structure and functions a color tft (thin film transistor) lcd module is comprised of a tft liquid crystal panel structure, lsis for driving the tft array, and a backlight assembly. the tft panel structure is created by sandwiching liquid crystal material in the narrow gap between a tft array glass substrate and a color filter glass substrate. after the driver lsis are connected to the panel, the backlight assembly is attached to the backside of the panel. rgb (red, green, blue) data signals from a source system is modulated into a form suitable for active matrix addressing by the onboard signal processor and sent to the driver lsis which in turn addresses the individual tft cells. acting as an electro-optical switch, each tft cell regulates light transmission from the backlight assembly when activated by the data source. by regulating the amount of light passing through the array of red, green, and blue dots, color images are created with clarity. outline of characteristics (at room temperature) display area 304.128 (h) 228.096 (v) mm drive system a-si tft active matrix display colors full-color number of pixels 1024 768 pixel arrangement rgb vertical stripe pixel pitch 0.297 (h) 0.297 (v) mm module size 350.0 (h) 265.0 (v) 20.0 (d) mm weight 1480 g (typ.) contrast ratio 200:1 (typ., perpendicular) best contrast ratio 350:1 (typ., down side 10 ) viewing angle (more than the contrast ratio of 10:1) ? horizontal : 55 (typ., left side, right side) ? vertical : 50 (typ., up side), 45 (typ., down side) designed viewing direction ? wider viewing angle with contrast ratio : down side (6 oclock) ? wider viewing angle without image reversal : up side (12 oclock) ? optimum grayscale ( g = 2.2) : perpendicular color gamut 42 % (typ., at center, to ntsc) response time 15 ms (typ.), white to black luminance 200 cd/m 2 (typ.) input signals analog rgb, vsync and hsync backlight edge light type: two cold cathode fluorescent lamps with an inverter inverter p/n: 150pw031 lamp holder set p/n: 150lhs03 supply voltage 12 v, 12 v (logic/lcd driving, backlight) power consumption 18.4 w (typ.)

data sheet en0418ej1v0ds00 28 NL10276AC30-03A general cautions next figures and sentences are very important. please understand these, then read the text of a book. caution this figure is a mark that you will get hurt and/or the module will have damages when you make a mistake to operate. this figure is a mark that you will get an electric shock when you make a mistake to operate. this figure is a mark that you will get hurt when you make a mistake to operate caution do not touch an inverter--on which is stuck a caution label--while the lcd module is under the operation, because of dangerous high voltage. (1) caution when taking out the module <1>pick the pouch only, in taking out module from a carrier box. (2) caution for handling the module <1> as the electrostatic discharges may break the lcd module, handle the lcd module with care against electrostaic discharges. <2> as the lcd panel and backlight element are made from fragile glass material, impulse and pressure to the lcd module should be avoided. <3> as the surface of polarizer is very soft and easily scratched, use a soft dry cloth without chemicals for cleaning. <4> do not pull the interface connectors in or out while the lcd module is operating. <5> put the module display side down on a flat horizontal plane. <6> handle connectors and cables with care. <7> when the module is operating, do not lose clk, hsync, or vsync signal. if any one of these signals is lost, the lcd panel would be damaged. <8> the torque of mounting screw should be 0.392 nm (4 kgfcm).less. (3) caution for the atmosphere <1> dew drop atmosphere should be avoided. <2> do not store and/or operate the lcd module in a high temperature and/or high humidity atmosphere. storage in an electro-conductive polymer packing pouch and under relatively low temperature atmosphere is recommended. <3> this module uses cold cathode fluorescent lamps. therefore, the life time of lamps becomes short if the module is operated under the low temperature environment. (4) caution for the module characteristics <1> do not apply the fixed pattern for a long time to the lcd module. it may cause image sticking. please use the screen savers if the display pattern is fixed for a long time. <2> this module has the retardation film which may cause the variation of the color hue in the different viewing angles. the ununiformity may appear on the screen under the high temperature operation. <3> the light vertical stripe may be observed depending on the display pattern. this is not defects or malfunctions.
data sheet en0418ej1v0ds00 29 NL10276AC30-03A <4> the noise from the inverter circuit may be observed in the luminance control mode. this is not defects or malfunctions. (5) other cautions <1> do not disassemble and/or reassemble lcd module. <2> do not readjust any variable resistors or switches in the module. <3> when returning the module for repair or etc., please pack the module properly to avoid any damages. we recommend using the original shipping packages. <4> in case that the scan converter is used to convert vga signal to ntsc, it is recommended using the frame-memory type, not the line-memory. liquid crystal display has the following specific characteristics. there are not defects or malfunctions. the display condition of lcd module may be affected by the ambient temperature. the lcd module uses cold cathode tube for backlight. optical characteristics, like luminance or uniformity, will change during time. uneven brightness and/or small spots may be noticed depending on different display patterns.
