1.DESCRIPTION NL128102AC31-01E is a TFT (thin film transistor) active matrix color liquid crystal display (LCD) comprising amorphous silicon TFT attached to each signal electrode, a driving circuit and a backlight. NL128102AC31-01E has a built-in backlight with an inverter.
The 51cm(20.1" Type) diagonal display area contains 1280 1024 pixels and can display full-color (more than 16 million colors simultaneously). Also, it has wide viewing angle and multi-scan function. Therefore, this module is so called Super Fine TFT.
2. FEATURES Ultra wide viewing angle with lateral electric field. High luminance and Low reflection Analog RGB signals Multi-scan function: e.g., SXGA, XGA, SVGA, VGA, VGA-TEXT, MAC, SUN Direct type backlight (twelve lamps, Inverter) Replaceable backlight unit and inverter On Screen Display Approved by UL1950 Third Edition (File No. E170632) and CAN/CSA-C22.2 No.950-95 (File No. E170632) VESA: DPMS: DDC1: DDC2B: Video Electronics Standards Association Display Power Management Signaling Display Data Channel 1 Display Data Channel 2B
3. APPLICATIONS Engineering work stations, Desk-top type of PCs Display terminals for control system Monitors
4. 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. Sandwiching liquid crystal material in the narrow gap between a TFT array glass substrate and a color filter glass substrate creates the TFT panel structure. 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 are 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.

ATENTION
Voltage Logic signals POWC VDD 200ms < 0< 0< Time Wrong power sequence may damage the module. Note 1
100ms<
Note 1: Synchronous signals, Control signals, CLK Voltage <800ms 12.0V 10.8V BRTC
VDDB Time 0< 0<
(1) When VCC is not supplied, Logic signals (synchronous signals and control signals) should be "0" voltage (V). If these input voltages are higher than 0.3 V, 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, and Vsync is not input more than 90 ms typically. As the display data are unstable in this period, the display maybe disordered. But the backlight works correctly even this period. So the backlight should be controlled by BRTC signal. (3) Backlight should be turned on or off, while logic signals are supplied. The backlight power supply (VDDB) is not relative to the power supply sequence. However, unstable data will be displayed when the backlight power is turned ON /OFF without 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 inputs are independent from this power supply sequence. (6) 12V for backlight should be started up within 800ms, otherwise, the protection circuit makes the backlight turn off. (7)The backlight is turned off with safety circuit, when "L" period of BRTP signal is input more than 50 ms. (8) Do not input "H" ACA and PWSEL, when VDD is 0V or BRTC is "L". NEC Corporation

Note 1: The power supply lines (VDDB and GNDB) have large ripple voltage while dimming. There is the possibility that the ripple voltage produce an acoustic noise and signal wave noise in a system circuit ( e.g. audio circuit). If the noise occurred in a system circuit, please assembles an aluminum electrolytic capacitor (5000 to 6000 F) between the power source lines (VDDB and GNDB), and the aluminum electrolytic capacitor will be able to reduce the noise.

Supply voltage Part No. Supplier Ratings Remarks VDD CCP2E50 KOA 2A VDDB R451007 LITTEL FUSE 7A Remarks: When customer designs the power supply, above fuse specification should be considered. The power capacity should be more than 2.0 times of fuses rating. If the power capacity is smaller than 2.0 times of fuses rating, from safety point of view, enough evaluation is required for customer's application.

7.7.1 HOW TO USE THE ABOVE FUNCTIONS If CNTSEL is "L", the above functions( (1)-(5) )are valid. (CNTSEL is "H" or open, default values are valid.) After serial data are transferred, the data is latched by CNTSTB. Once, the data is latched, the above functions( (1)-(5) ) are effective. If ADJSEL is "L", the above functions( (6)-(7) )are valid. (ADJSEL is "H" or open, default values are valid.) After serial data are transferred, the data is latched by CNTSTB2. Once, the data is latched, the above functions( (6)-(7) ) are effective. Please keep CNTSTB/2 to be "L" during transferring data. Input data can be changed during power on, but LCD display may be disturbed. When the serial data are changed, we recommend that the backlight power is off using BRTC function.

note 2: This delay value is typical value at Ta=25 . And the value varies by the ambient temperature and the module itself. Please set up a preferable display position. See the following references. Q Variation of CLK delay by temperature drift. (only reference) The temperature constant of CLK delay is 0.2%/ . Calculated example: In case of delay time is 20ns at Ta=25 ; (a) In case Ta rising to 50 . Increase of delay time (50 25 ) 0.002 20ns +1ns So, the total delay time is 21 ns at Ta=50 . (b) In case Ta falling to 0 . Decrease of delay time (0 25 ) 0.002 20ns -1ns So, the total delay time is 19 ns at Ta=0 . R Variation of CLK delay time against each LCD module. (only reference)

DOD-M-0208 7.8 EXPANSION FUNCTIONS 7.8.1 HOW TO USE EXPANSION MODES
26/46
Expansion mode is a function of expanding an image. For example, VGA signal has 640 480 pixels. But, if the display data expand to 2.0 times vertically and horizontally, VGA screen image will be displayed fully on the screen of SXGA resolution. This LCD module has the function that expands display images vertically and horizontally as shown in below table. When each mode of input signals, which are shown at item 15. (page 34), is supplied to LCD module, display image is expanded automatically. Please adopt expansion function after evaluating image quality, because the expanded image is relatively bad depending on displayed images. The followings show magnification rate of each mode. Magnification Display Number of Mode display data Vertical Horizontal note 1 (pixels) SXGA 1280 x 1024 1 1 XGA 1024 x 768 1.25 1.25 SVGA 800 x 600 1.6 1.6 VGA 640 x 480 2.0 2.0 VGA text 720 x 400 2.5 1.7 MAC 832 x 624 1.6 1.5 SUN 1152 x 900 1.1 1.1 note 1: 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(108.0MHz) 1.0=108.0MHz VGA : System CLK(25.175MHz) 2.0= 50.25MHz

When PWSEL="L", outside control is valid. Luminance is controlled by the duty ratio of input signal of BRTP. Duty=100%: maximum luminance Duty=20%: minimum luminance BRTC must not be fixed on "L", in case of PWSEL= "L" and BRTC ="H" or "Open". Otherwise, the inverter will stop to work. Once inverter stops, even if BRTP pulse comes, the backlight will not turn on again. In this situation, please supply powers (VDDB) to the inverter again. Timing for BRTP BRTC 0tLPW50ms

8. PRECAUTIONS
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 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.
CAUTIONS
Do not touch an inverter --on which a caution label is stucked-- while the LCD module is working, because of dangerous high voltage. (1) Caution when taking out the module Pick the pouch only, when in taking out the module from the carrier box. (2) Cautions for handling the module As the electrostatic discharges may break the LCD module, handle the LCD module with care against electrostatic discharges.
As the LCD panel and backlight element are made from fragile glass material, impulse and pressure to the LCD module should be avoided. As the surface of polarizer is very soft and easily scratched, use a soft dry cloth without chemicals for cleaning. Do not pull the interface connectors in or out while the LCD module is operating. Put the module display side down on a flat horizontal plane. Handle connectors and cables with care. When the module is operating, do not lose CLK, Hsync, or Vsync signal. If any one or more of these signals is lost, the LCD panel would be damaged. Do not put front side (display surface side ) of the module on a desk or a table for a long time, because the display may become un-uniformity. Don't push or rub the surface of LCD module. If you do the scratches or the rubbing marks may left on the surface of the module. The torque for mounting screw should never exceed 0.451 N m (4.6kgf cm) Do not give the stress too much on interface connectors. The module may become function deficiency by a contact defective and damages. Pay attention to handling at the time of matching connector connection and in the connection condition. NEC Corporation

(3) Cautions for the atmosphere Dew drop atmosphere must be avoided. Do not store and/or operate the LCD module in high temperature and/or high humidity atmosphere. Storage in an Electro-conductive polymer packing pouch and under relatively low temperature atmosphere is recommended. This module uses cold cathode fluorescent lamps. Therefore, the life-time of lamps becomes short conspicuously at low temperature. Do not operate the LCD module in high magnetic field. (4) Cautions for the module characteristics Do not apply any fixed patterns data signal for a long time to the LCD module. It may cause image sticking. Use screen savers if the display pattern is fixed more than 30 minutes. The noise from the inverter circuit may be observed in the luminance control mode. This is neither defects nor malfunctions. (5) Other cautions Do not disassemble and/or reassemble LCD module. Do not readjust variable resistors nor switches etc. When returning the module for repair or etc., pack the module not to be broken. We recommend the original shipping packages. Liquid Crystal Display has the following specific characteristics. There are not defects nor malfunctions. The ambient temperature may affect the display condition of LCD module. 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.
