data sheet en0444ej1v0ds00 2 NL10276AC28-01L 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) items description display area 285.696 (h) 214.272 (v) mm drive system a-si tft active matrix display colors full-color number of pixels 1024 (h) 768 (v) pixel arrangement rgb vertical stripe pixel pitch 0.279 (h) 0.279 (v) mm module size 330.0 (h) 255.0 (v) 19.8 (d) mm (typ.) weight 1230 g (typ.) contrast ratio 150:1 (typ.) viewing angle (more than the contrast ratio of 10:1) ? horizontal : 50 (typ., left side, right side) ? vertical : 20 (typ., up side), 35 (typ., down side) designed viewing direction ? optimum grayscale ( g = 2.2): perpendicular ? wider viewing angle with contrast ratio: down side ( 6 oclock) ? wider viewing angle without image reversal: up side (12 oclock) color gamut 40% (typ., at center, to ntsc) response time 11 ms (typ.), white 100% to black 10% luminance 200 cd/m 2 (typ.) input signals analog rgb signals, synchronous signals (hsync and vsync or composite) backlight edge light type: two cold cathode fluorescent lamps with an inverter lamp holder : 141lhs08 inverter : 141pw111 supply voltage 12 v, 12 v (logic/lcd driving, backlight) power consumption 16.0 w (typ.)

data sheet en0444ej1v0ds00 13 NL10276AC28-01L notes 1 : even if the preset timing is entered, a little adjustment of the functions such as horizontal period, clk- delay and display position, are required. the adjusted values are memorized in every preset no. 2 : this module recognizes the synchronous signals with near preset timing of the frequency of hs, vsync, even in the case that the signals other than the preset timing were entered. for instance, the module shows the display with presetting number 6 in the case of the following conditions: 640 480 dot; hs: 37.861khz; vsync: 72.809 hz. please note that using out of the preset timings may cause wrong magnification ratio, unfitness of control functions or other improper displays. 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 to expand the screen size in different resolutions. for example, vga signal has 640 480 pixels. but, if the display data can be expanded to 1.6 times vertically and horizontally, vga screen image can be displayed fully on the screen of 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 become bad in some cases. the followings show display magnifications for each mode. magnification input display 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 hiearchical / toggle 1.42 mac 832 624 1.2 1.2

data sheet en0444ej1v0ds00 34 NL10276AC28-01L general cautions because next figures and sentences are very important, please understand these contents as follows. 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 pick the pouch only, in taking out 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) when the module is operating, do not lose clk, hs or vsync signal. if any one of these signals is lost, the lcd panel would be damaged. h) the torque to mounting screw should never exceed 0.392 nm (4 kgfcm). (3) cautions for the 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 under relatively low temperature atmosphere, is recommended. c) this module uses cold cathod fluorescent lamps. therefore, the life time of the lamps becomes short conspicuously at low temperature. d) do not operate the lcd module in a high magnetic field. (4) caution for the module characteristics a) do not apply the fixed pattern for a long time to the lcd module at product againg. applying fixed pattern for a long time may cause image sticking.
data sheet en0444ej1v0ds00 35 NL10276AC28-01L (5) other cautions a) do not disassemble and/or reassemble lcd module. b) do not readjust any variable resistors, switches, etc. c) when returning the module for repair etc., please pack the module not to be broken. we recommend to the original shipping packages. liquid crystal display has the following specific characteristics. there are neither defects nor malfunctions. the display condition of 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 during time. uneven brightness and/or small spots may be noticed depending on different display patterns.
