data sheet en0512ej1v0ds00 2 NL10276AC30-03L structure and function 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 back side of the panel. rgb (red, green, blue) data signals from a source system are modulated into a form suitable for active-matrix addressing by the onboard signal processor and sent to the driver lsis, which in turn address 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. characteristics (at room temperature) items description display area 304.128 (h) 228.096 (v) mm drive system a-si tft active matrix display colors fullcolor number of pixels 1024 (h) 768 (v) pixel arrangement rgb vertical stripe pixel pitch 0.297 (h) 0.297 (v) mm module size 350.0 (h) 265.0 (v) 22.5 (d) mm (typ.) weight 1680 g (typ.) contrast ratio 250:1 (typ.) viewing angle (more than the contrast ratio of 10:1) ? horizontal: 55 (typ., left side, right side) ? vertical: 45 (typ., up side, down side) designed viewing direction ? optimum gray-scale ( g = 2.2): perpendicular ? best contrast angle: down side 5 color gamut 40% (typ., at center, to ntsc) response time 15 ms (typ.), white 100% to black 10% luminance 350 cd/m 2 (typ.) signal system analog rgb signals, synchronous signals (hsync and vsync or composite) backlight edge light type: four cold cathode fluorescent lamps with an inverter lamp holder: 150lhs13 inverter: 150pw131 supply voltage 12 v, 12 v (logic/lcd driving, backlight) power consumption 28.2 w (typ.) www..net www..net

(2) if the power supply voltage is applied while up and down are connected to gnd, the input control signals become ineffective and all key inputs are neglected. to reset this mode, turn off the power once and then turn on the power while up and down are connected to gnd. the mode will be released. (3) do not change the menusel setting while the module is being operated. menusel selection (hierarchical type or toggle type) is continuously set during the power supply voltage is applied.

data sheet en0512ej1v0ds00 14 NL10276AC30-03L remarks 1: even if the one of preset timing is entered, a little adjustment of the functions such as horizontal period, clk delay and display position is required. the adjusted values are memorized in every preset number. 2: this module recognizes the synchronous signals with near preset timing of the frequency of hs, vsync, even if the signals other than the preset timing that were entered. for instance, it is displayed with presetting number 6 in the case of 640 480 dot; hs: 37.861khz; vsync: 72.809 hz. please note that using other than the preset timings may cause incorrect magnification ratios, unfitness of control functions, or other display problems. 3: the display color scale may be different between sync on green input and the others. control functions (1) expansion modes expansion mode is a function by which expand the screen size in different resolutions. for example, the vga signal has 640 480 pixels. but if the display data can be expanded to 1.6 times vertically and horizontally, the vga screen image can be displayed fully on a screen with xga resolution. this module automatically recognizes the timing shown in preset timing as an expansion mode. please adopt this mode after evaluating display quality, because the appearance in expansion mode may degrade in some cases. the following table shows display magnifications for each mode. magnifications input signals number of pixels vertical horizontal xga 1024 768 1.0 1.0 svga 800 600 1.25 1.25 vga 640 480 1.6 1.6 vga text 720 400 1.92 / 1.6 hierarchical/toggle 1.42 mac 832 624 1.2 1.2 www..net www..net

data sheet en0512ej1v0ds00 40 NL10276AC30-03L general cautions because the following figures and statements are very important, please be sure you understand their contents completely. caution this figure is a warning that you will get hurt and/or the module will be damaged if you make a mistake in operation. this figure is a warning that you will get an electric shock if you make a mistake in operation. this figure is a warning that you will get hurt if you make a mistake in operation. caution do not touch an inverter on which there is a caution label while the lcd module is in operation, because of dangerous high voltage. (1) caution when taking out the module pick up the pouch only, when removing the module from a carrier box. (2) cautions for handling the module a) as the electrostatic discharges may break the lcd module, handle the lcd module with care against electrostaic discharges. b) as the lcd panel and backlight element are made from fragile glass material, impulse and pressure to the lcd module should be avoided. c) as the surface of polarizer is very soft and easily scratched, use a soft dry cloth without chemicals for cleaning. d) do not pull the interface connectors in or out while the lcd module is operating. e) put the module display side down on a flat horizontal plane. f) handle connectors and cables with care. g) y the torque to mounting screw should never exceed 0.392 nm (4 kgfcm). h) y do not give the stress to interface connectors. the module may become function deficiency by a contact defective and damages. pay attention to handling at the time of matching connector connection and in the connection condition. (3) cautions regarding atmosphere a) dew drop atmosphere should be avoided. b) 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 in a relatively low-temperature atmosphere is recommended. c) this module uses cold cathode fluorescent lamps. the life time of the lamps is shortened conspicuously at low temperatures. d) do not operate the lcd module in high magnetic field. (4) cautions about the module characteristics a) do not apply a fixed pattern data signals to thelcd module at product aging. applying a fixed pattern for a long time may cause image sticking. www..net www..net
data sheet en0512ej1v0ds00 41 NL10276AC30-03L (5) other cautions a) do not disassemble and/or reassemble the lcd module. b) do not readjust variable resistor or switch, etc. c) when returning the module for repair, etc., please pack the module so it will not be broken. we recommend using the original shipping packages. the liquid crystal display has the following specific characteristics. these are neither defects nor malfunctions. the display condition of the lcd module may be affected by the ambient temperature. the lcd module has cold cathode tube for backlight. optical characteristics, like luminance or uniformity, will change over time. uneven brightness and/or small spots may be noticed, depending on different display patterns. www..net www..net

(note) (1) "nec" as used in this statement means nec corporation and also includes its majority- owned subsidiaries. (2) "nec electronic component products" means any electronic component product developed or manufactured by or for nec (as defined above). de0202 www..net www..net
