data sheet en0509ej1v0ds00 2 nl128102ac28-01f 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. outline of characteristics (at room temperature) display area 359.04 (h) 287.232 (v) mm drive system a-si tft active matrix display colors fullcolor number of pixels 1280 1024 pixels pixel arrangement rgb vertical stripe pixel pitch 0.2805 (h) 0.2805 (v) mm module size 424.0 (h) 337.0 (v) 41.0 (d) mm (typ.) weight 2130 g (typ.) contrast ratio 300 : 1 (typ.) viewing angle (more than the contrast ratio of 10 : 1) horizontal: 85 (typ., left side, right side) vertical: 85 (typ., up side, down side) design viewing direction optimum grayscale ( g = 2.2): perpendicular color gamut 60% (typ., at center, to ntsc) response time 40 ms (typ.), "black" (0%) to "white" (90%) luminance 200 cd/m 2 (typ.) signal system analog rgb signals, synchronous signals (hsync and vsync or composite), digital data supply voltages 12 v (logic/lcd driving), 12 v (backlight) backlight direct type: eight cold cathode fluorescent lamps with an inverter ? inverter: part no. 181pw031 ? backlight unit: part no. 181lhs03 power consumption 43.2 w (typ.) data sheet en0509ej1v0ds00 3 nl128102ac28-01f block diagram lcd module i/f board i/f r g b r g b amp sync. division pll aif amp timing controller sync. signal power controller (signal recognition) hs : hsync cs : composite synchronous signal note fg (frame ground) is not connected to gnd nor gndb. gnd is connected to gndb. on/off dc/dc converter dc/dc converter inverter luminance (on/off) hs/cs vsync v dd (+12 v) v ddb (+12 v) gndb gnd fg clk v-driver v-driver backlight h-driver 3840 lines lcd panel 1024 lines 1024 lines h: 1280 3 (r,g,b) v: 1024 v dd ledon ledoff led00 to 12 sel up down exit volsel osdsel menusel ddcclk ddcdat wprt brtvol osd data sheet en0509ej1v0ds00 4 nl128102ac28-01f general specifications item specification unit module size 424.0 1.0 (h) 337.0 1.0 (v) 42.0 (max.)

preset timing that were entered. for instance, it is displayed with presetting number 6 in the case of 640 480 dot, hs: 37.861 khz, vsync: 72.809 hz an example). adopt the evaluation, because adjustment may not fit in the case that the magnifying ratio differs if you use it with the signals other than the display timing that was preset. data sheet en0509ej1v0ds00 24 nl128102ac28-01f 4.

screen size in different resolutions. for example, the vga signal has 640 480 pixels. but if the display data can be expanded to 2.0 times vertically and horizontally, the vga screen image can be displayed fully on a screen with sxga resolution. this module automatically recognizes the timing shown in preset timings as an expansion mode. please adopt this mode after evaluating display quality, because the appearance in the expansion mode may degrade in some cases. the following table shows the display magnifications for each mode. magnification input display number of pixels vertical

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. cautions do not touch an inverter, on which there is a caution label, while the lcd module is in operation, because of high voltage. (1) caution when taking out the module a) pick up the pouch only, when removing out the module from the carrier box. (2) cautions for handling the module a) y as the electrostatic discharges may break the lcd module, handle the lcd module with care against electrostatic discharges. b) as 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 that horizontal plane. f) handle connectors and cables with care. g) when the module is operating, do not lose clk, hs or vsync signal. if any one or more of these signals is lost, the lcd panel would be damaged. h) y the torque to mounting screw should never exceed 0.451 nm (4.6 kgfcm). i) y don't push or rub the surface of lcd module please. if you do the scratches or the rubbing marks may be left on the surface of the module. (3) cautions regarding atmosphere a) dew drop atmosphere should be avoided. b) do not store and/or operate the lcd module in high-temperature and/or high-humidity atmosphere. storage in an anti-static pouch and in a room temperature atmosphere is recommended. c) this module uses cold cathode fluorescent lamps. the lifetime of lamps is shortened if the module is operated at low temperatures. d) do not operate the lcd module in a high magnetic field. (4) cautions about the module characteristics a) y do not apply a fixed pattern for a long time to the lcd module at product aging. it may cause image sticking. use the screen savers if the display pattern is fixed for a long time. b) y 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 in the high-temperature operation. data sheet en0509ej1v0ds00 34 nl128102ac28-01f c) y the light vertical stripe may be observed depending on the display pattern. this is not defects nor malfunctions. d) y the noise from the inverter circuit may be observed in the luminance control mode. this is not defects nor malfunctions. (5) other cautions a) do not disassemble and/or reassemble the lcd module. b) do not readjust variable resistors or switches, etc. c) y when returning the module for repair, etc, pack the module so it will not be broken. we recommend using the original shipping packages. d) y 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. the liquid crystal display has the following specific characteristics. these are not defects nor malfunctions. ? the ambient temperature may affect the optical characteristics of this module. ? this 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. data sheet en0509ej1v0ds00 35 nl128102ac28-01f outline drawing: front view (unit: mm) 412 0.3 424 1 4? 4.6 0.2 364 0.3 (bezel opening) 3.1 +0.2 ?
