DOD-M-0433 1. OUTLINE 1.1 STRUCTURE AND PRINCIPLE
4/31
NL10276AC30-07 module is composed of the driver LSIs for driving the TFT (Thin Film Transistor) array with an amorphous silicon thin film transistor liquid crystal display (a-Si TFT LCD) panel structure and a backlight. The a-Si TFT LCD panel structure is injected liquid crystal material into the narrow gap between a TFT array glass substrate and a color filter glass substrate. 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 address the individual TFT cells. Working as an electro-optical switch, each TFT cell regulates transmitted light from the backlight assembly when worked by the data source. Color images are created by regulating the amount of transmitted light through the array of red, green and blue dots. 1.2 APPLICATIONS * FA monitor 1.3 FEATURES *Parallel 8bit interface (2 port) *Ultra-wide viewing angle (with lateral electric field) *Fast response time *High luminance *High contrast *Wide color gamut *Luminance control *Small foot print *Direct light type *Replaceable backlight unit and inverter

Note1: Display signals (DE, CLK, RA0 to RB7, GA0 to GB7, BA0 to BB7) must be "0" voltage (V), exclude the VALID period (See above sequence diagram). If input voltage to display signals is higher than 0.3V, the internal circuits might be damaged. Note2: The values of signals are measured at the termination resistor of 100 ohm. Note3: In terms of fall-off-potential while VDD leading edge is below 4.0V, protection circuits may work and then the module may not work. Note4: If display signals to this module are cut while this module is working, even if the signal input to it once again, it may not work normally. 4.4.2 Sequence for backlight inverter

Note1: Backlight ON/OFF should be controlled, while display signals are supplied. The backlight power supply (VDDB) is not related to the power supply sequence. However, unstable data may be displayed when the backlight power is turned ON/OFF during display signals out. Note2: Only when BRTC is Open.

Open
Note1: Luminance control may be overlap noises on the display image depending on input signal timing. In this case, keep off the interference between input signal and backlight driving signal, by PWM (Pulse Width Modulation) method. 4.6.2 Luminance control with external pulse Luminance control with external pulse activated when PWSEL is Low and external pulse signal is inputted to BRTP. This luminance control is controlled by duty ratio, and luminance is as follows. Duty ratio=100%: Max. luminance Duty ratio=30%: Min. luminance In case of BRTC = High or Open, the inverter will stop working when BRTP terminal is fixed to Low in the condition of PWSEL = Low. In this case, backlight will not turn on, even if external pulse signal is inputted to BRTP again. This is not out of order. Inverter will start to work when power is supplied again. The display image may be disturbed by luminance control with external pulse when set up frequency is interfered with internal signal frequency.

Note5: Definitions of response times are as follows. Response time is measured by photo-detector's out put level, when the luminance changes "black" to "white", or " black " to " white " on the same screen point. Ton is the time it takes the luminance to go from 10% to 90% on condition. Toff is the reverse of Ton (See the following diagram) White Luminance 100% 90%

DOD-M-0433 6. PRECAUTIONS 6.1 MEANING OF CAUTION SIGNS
26/31
The following caution signs have very important meaning. Be sure to understand following contents, respectively.
!
CAUTION
This sign has a meaning that customer will be injured himself and/or the module will sustain a damage, if he makes a mistake in operations.
This sign has a meaning that customer will get an electric shock if he makes a mistake in operations.
This sign has a meaning that customer will be injured himself if he makes a mistake in operations. 6.2 CAUTIONS
Do not touch HIGH VOLTAGE PART of the inverter while turn on. Customer will be in danger of an electric shock.
Pay attention to handling for the working backlight. It may be over 35C from ambient temperature. Do not shock and press the LCD panel and the backlight. There will be in danger of breaking, because they are made of glass. (Shock: To be not greater 294m/s2 (30G) and to be not greater 11ms, Pressure: To be not greater 19.6N (2kgf)) 6.3 ATTENTIONS (1) Handling the product x When customer pulls out products from carton box, take hold of both ends without touch the circuit board. If customer touches it, products may be broken down and/or out of adjustment, because of stress to mounting parts. y If customer places products temporarily, turn down the display side and place on a flat table. z Handle products with care and avoid electrostatic discharge (e.g. Decrease with earth band, ionic shower, etc.), because products (LCD modules) may be damaged by electrostatic. { The torque for mounting screws should never exceed 0.39Nm. Over torque may cause mechanical damage to the product. | Do not press or friction, because LCD panel surface is sensitive. If customer will clean the product surface, NEC Corporation or their supplier will recommend using the cloth with ethanolic liquid.

} Do not push-pull the interface connectors while turn on, because wrong power sequence may break down the product. ~ Connection cables such as flexible cable, and so on, are danger of damage. Do not hook cables nor pull them. (2) Environment x Dewdrop atmosphere must be avoided. y Do not operate and/or stores in high temperature and/or high humidity atmosphere. If customer store the product, keep in antistatic pouch in room temperature, because of avoidance for dusts and sunlight. z Do not operate in high magnetic field. Circuit boards may be broken down by it. { Use an original protection sheet on product surface (polarizer). Adhesive type protection sheet should be avoided, because it may change color and/or properties of the polarizer. (3) Specification for products x Do not display the fixed pattern for a long time because it may cause image sticking. If the fixed pattern is displayed on the screen, use a screen saver. y The product may be changed of color by viewing angle because of the use of condenser sheet for backlight unit. z The product may be changed of luminance by voltage variation, even if power source applies recommended voltage to backlight inverter. { Optical characteristics may be changed by input signal timings. (4) Other x All GND, GNDB, VDD and VDDB terminals should be connected without a non-connected signal line. y Do not disassemble a product and/or adjust volume. z If customer would like to replace backlight lamps, see 'REPLACEMENT MANUAL FOR BACKLIGHT'. { If customer use screwnails, pay attention not to insert waste materials in inside of products. | When customer returns product for repair and so on, pack it with original shipping package because of avoidance of some damages during transportation.
General specifications for the LCD The following items are neither defects nor failures. Response time, luminance and color gamut may be changed by ambient temperature. The LCD may be seemed luminance uniformity, flicker, vertical seam and/or small spot by display patterns. Optical characteristics (e.g. luminance, display uniformity, etc.) gradually is going to change depending on operating time, and especially low temperature, because the LCD has cold cathode fluorescent lamps.
