data sheet 2 NL160120AC27-01A 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 432.0 (h) drive system a-si tft active matrix display colors full-color number of pixels 1600 1200 pixel arrangement rgb vertical stripe pixel pitch 0.270 (h) module size 470.0 (h) 382.0 (v) 41.6 (d) mm (typ.) weight 3050 g (typ.) contrast ratio 250:1 (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) designed viewing direction optimum grayscale ( = 2.2): perpendicular color gamut 60% (typ., at center, to ntsc) response time 20 ms (typ.), ?black? to ?white? luminance 200 cd/m 2 (typ.) input signals analog rgb signals, synchronous signals (vsync and hsync or composite), digital data backlight direst type: 12 cold cathode fluorescent lamps with an inverter 3 nl160120ac28-01a data sheet block diagram lcd module i/f board r g b r g b amp sync. division pll aif amp timing controller sync. signal power controller (signal recognition) on/off dc/dc converter dc/dc converter inverter luminance (on/off) hs/cs vsync v dd (+12 v) gnd v dd b (+12 v) gndb clk v-driver backlight h-driver 4800 lines lcd panel 1200 lines h: 1600 3 (r,g,b) v: 1200 v dd ledon ledoff sel up down exit left right reset btnsel menusel osd note frame ground and gnd are connected in this module. gndb is not connected to frame ground. data sheet 4 NL160120AC27-01A specifications general specifications item contents unit module size 470.0 1.0 (h) 382.0 1.0 (v) 42.5 (max.)

in mind slight adjustment (multiplication value, clock delay, and display location) is required as a result of equipment variation even if input is performed with the display timing of this table. readjustment, however, is unnecessary because adjusted values are stored in memory for every preset number. display is controlled with preset timing near hs and vsync frequency even if a signal with a timing other than the preset display timing is input. 21 1600 x 1200 60.000 75.000 162.000 3 46 192 304 +,+ vesa data sheet 13 NL160120AC27-01A 2. the device may not function normally if a signal is input that differs from the timing shown in the above table by a large margin. in addition, the device will not operate normally if waveforms are distorted by rounding of hsync or vsync waveforms, noise, and others factors, even for a signal with the same timing as shown above. example for 640 480 dots, hs: 37.861 khz, and vsync: 72.809 hz, the image is displayed with preset number 6. adjustment may not be synchronized if the expansion rate (scaling factor) or other values differ when the device is used with a display timing other than a preset one. therefore, only use a non-preset display timing after careful evaluation. 3. display colors may change during sync on green (song) input. 4. song signal types: (1) song type a an equivalent hsync pulse is not present during vsync

is memorized in the lcd module every display modes and every preset timing, therefore, it is not necessary to see up the values every time when the power is turned on. however, adjusted values are not memorized in case of that the adjustment mode is changed during the set of value or the power is turned off. auto adjust is affected by the system pcs and display modes. in this case, manual adjustment is required. in case of input signals are different from the preset timing, information shows you a different resolution. the adjustment ranges of position are deviated when osd position is changed. therefore, the display position might be affected. the display is momentally disturbed during adjustment. auto adjust does not function correctly when both sync on green and separate sync signals are input. in this case, manual adjustment is required. control functions function items the input video signals to this lcd module can be adjusted by sel/up/down/left/right/reset/exit
