data sheet en0416ej1v0ds00 2 NL10276AC30-03 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 1400 g (typ.) contrast ratio 200:1 (typ., perpendicular) 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.) signal system analog rgb signals, synchronous signals (hsync and vsync), clk supply voltage 12 v, 12 v (logic/lcd driving, backlight) backlight edge light type: two cold cathode fluorescent lamps with an inverter [replaceable parts] ? lamp holder : 150lhs03 ? inverter : 150pw031 power consumption 15.6 w (typ.)

(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 lcd modules, handle lcd modules with care against electrostaic discharges. <2> as lcd panels and backlight elements are made from fragile glass material, impulse and pressure to lcd modules should be avoided. <3> as the surface of polarizer is very soft and easily scratched, use soft dry cloth without chemicals for cleaning. <4> do not pull the interface connectors in or out while lcd module is operating. <5> put modules display side down on a flat horizontal plane. <6> handle connectors and cables with care. <7> the torque of mounting screw should be 0.392 nm (4 kgfcm) or less. (3) caution for the atmosphere <1> dew drop atmosphere should be avoided. <2> do not store and/or operate lcd modules in a high temperature and/or highly humid 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 conspicuously at low temperature. <4> do not operate lcd modules in a high magnetic field. (4) caution for the module characteristics <1> do not apply fixed pattern data signal to the lcd module at product aging. applying fixed pattern for a long time may cause image sticking.
