data sheet en0427ej1v0ds00 2 nl128102ac23-02a 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. block diagram lcd module i/f board r g b r g b amp sync. division pll aif amp timing controller sync. serial power controller (signal recognition) on/off dc/dc converter dc/dc converter inverter luminance (on/off) hsync/csync vsync v dd (+12 v) gnd v dd b (+12 v) gndb clk v-driver backlight h-driver 3840 lines lcd panel 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 note neither gnd nor gndb is connected to frame.

data sheet en0427ej1v0ds00 28 nl128102ac23-02a expansion function (reference) (1) how to use expansion mode expansion mode is a function to expand screen. for example, vga signal has 640 480 pixels. but, if the display data can expanded to 2.0 times vertically and horizontally,vga screen image can be displayed fully on the screen of sxga resolution. this lcd module has the function that expands vertical direction as shown in the following table. and expanding horizontal direction is possible by setting input clk frequency equivalent to the magnification. it is necessary to make this clk outside of this lcd module. please adopt this mode after evaluating display quality, because the appearance in the expansion mode is happened to be relatively bad in some cases. the followings show the display magnifications for each mode. magnification input display number of pixels vertical horizontal note sxga 1280 1024 1 1 xga 1024 768 1.25 1.25 svga 800 600 1.6 1.6 vga 640 480 2.0 2.0 vga text 720 400 2.5 1.7 mac 832 624 1.6 1.5 note the horizontal magnification multiples the input clock (clk). input clk = system clk horizontal magnification. example in case of sxga and vga, clk frequency can be decided as follows. sxga: (system clk (108.0 mhz)) 1.0 = 108.0 mhz. vga : (system clk (25.175 mhz)) 2.0 = 50.35 mhz.

data sheet en0427ej1v0ds00 35 nl128102ac23-02a general cautions next figures and sentence 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 a) 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 electrostatic 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 that horizontal plane. f) handle connectors and cables with care. g) 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. 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 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 fixed pattern data signal for a long time to the lcd module at product aging. applying fixed pattern for a long time may cause image sticking.
data sheet en0427ej1v0ds00 36 nl128102ac23-02a (5) other cautions a) do not disassemble and/or reassemble lcd module. b) do not readjust variable resistors or switches, etc. c) 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 backlighting. optical characteristics, like luminance or uniformity, will change during time. ? uneven brightness and/or small spots may be noticed depending on different display patterns.
