NL10276AC28-01 2 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 285.696 (h) 214.272 (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 0.279 (h) 0.279 (v) mm module size 330.0 (h) 255.0 (v) 19.0 typ.

NL10276AC28-01 6 supply voltage sequence note synchronous signal, control signals caution wrong power sequence may damage to the module. (1) logic signals (synchronous signals and control signals) should be 0 voltage (v), when vdd is not input. if higher than 0.3 v is input to signal lines, the internal circuit will be damaged. (2) lcd module will shut down the power supply of driving voltage to lcd panel internally, when one of clk, hsync, vsync, de (at de mode) is not input more than 90 ms typically. as the display data are unstable in this period, the display is disordered. but the backlight works correctly event this period. so the backlight on/off should be controlled by brtc signal. (3) the on/off switching of backlight while logic signals are supplied. the backlight power supply (vddb) is not related to the power supply sequence. however, unstable data will be displayed when the backlight power is turned on/off with no logic signals. (4) keep powc signal l more than 200 ms after the power supply (vdd) is input, if powc signal is controlled. (5) analog rgb input are independent from this power supply sequence. interface pin connection (1) cn1 part no. : mrf03-6r-smt adaptable socket : mrf03-2 6p-1.27 (for cable type) or mrf03-6pr-smt (for board to board type) supplier : hirose electric co.,ltd.

NL10276AC28-01 25 next figures and sentence 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 the lcd module will give out smoke or catch fire 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 electrostatic 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.
NL10276AC28-01 26 <3> this module uses cold cathode fluorescent lamps. therefore, the life time of lamps becomes short conspicuously at low temperature. <4> do not operate the lcd module 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. (5) other cautions <1> do not disassemble and/or reassemble lcd module. <2> do not readjust variable resistor or switch etc. <3> when returning the module for repair or 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 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.
