NL10276AC28-01E 2 structure and functions a color tft (thin film transistor) lcd module is comprised o f a tft liquid crystal panel structure, lsis for driving the tft array, and a backlight assembly. the tft panel structur e is created by sandwiching liquid crystal material in the narrow gap between a tft array glass substrate and a col or filter glass substrate. after the driver lsis are connected to the panel, the backlight assembly is attached t o 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 l ight 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.

NL10276AC28-01E 6 (1) supply sequence note synchronous signal, control signals and clk caution wrong power sequence may damage to the module. (a) logic signals (synchronous signals and control signals) shou ld be ? 0 ? voltage (v), when vdd is not input. if higher than 0.3 v is input to signal lines, the internal circuit wi ll be damaged. (b) lcd module will shut down the power supply of driving voltag e to lcd panel internally, when one of clk, hsync, and vsync, de (at de mode) is not input more than 90 ms typi cally. as the display data are unstable in this period, the display is disordered. but the backlight works correctl y event this period. so the backlight on/off should be controlled by brtc signal. (c) the on/off switching of backlight while logic signals are su pplied. the backlight power supply (vddb) is not related to the power supply sequence. however, unstable dat a will be displayed when the backlight power is turned on/off with no logic signals. (d) keep powc signal ? l ? more than 200 ms after the power supply (vdd) is input, if powc signal is controlled. (e) analog rgb input are independent from this power supply sequ ence. vdd t1ime logic signals note voltage 200 ms < 0 ms < (f) the power supply of backlight vddb should be the rated voltage witin 80ms after turn-on. otherwise, the protection circuit makes the backlight turn off. (2) ripple of supply voltage please note that the ripple at the input connector of the mo dule should be within the values shown below. if the ripple would be beyond these values, the noise might appear on th e screen. power supply note a coaxial cable shield should be connected with gnd. example of rhe power supply connection (a) separate power supply (b) put filters vdd (for logic and lcd driver) acceptable range < 100 mvp-p vddb (for backlight) < 200 mvp-p power power power filter * filter * vdd vddb vddb vdd * filter reference value l = 10 m h to 100 m h c = 10 m f to 100 m f - - www..net www..net

NL10276AC28-01E 18 expansion function 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 1.6 times vertically and horizontally, vga screen image can be displayed fully on the screen of xga resolution. this lcd module has the function of expanding vertical direc tion as shown in table 1. and expanding horizontal direction is possible by setting input clk frequency which i s equivalent to the magnification. it is necessary to make this clk outside of this lcd module. the below image is display example, when de function is defa ult and hd and vd is set to most suitable frequency. and when de function is used, hd and vd become default. adj ustment the display to the best position by de signal. please adopt this mode after evaluating display quality, bec ause the appearance of expansion mode is happened to become bad some cases. table 10. color adjust select data (daa3 to daa0: 4 bit) daa3 daa2 daa1 daa0 function 0000 prohibit 0001 main contrast notes 1. see more detail on color control function and graph image . 0010 prohibit 0011 prohibit 0100 sub-contrast r 0101 sub-contrast g 0110 sub-contrast b 0111 sub-brightness r 1000 sub-brightness g 1001 sub-brightness b 1010 prohibit 1100 prohibit 1101 prohibit 1110 prohibit 1111 prohibit www..net www..net
