1. OUTLINE

1.1 STRUCTURE AND PRINCIPLE

Monochrome LCD module NL256204AM15-01 and NL256204AM15-01A are composed of the amorphous silicon thin film transistor liquid crystal display (a-Si TFT LCD) panel structure with driver LSIs for driving the TFT (Thin Film Transistor) array and a backlight.

The a-Si TFT LCD panel structure is injected liquid crystal material into a narrow gap between the TFT array glass substrate and a monochrome-filter glass substrate.

Grayscale data signals from a host system (e.g. PC, signal generator, etc.) are modulated into best form for active matrix system by a signal processing board, and sent to the driver LSIs which drive the individual TFT arrays.

The TFT array as an electro-optical switch regulates the amount of transmitted light from the backlight assembly, when it is controlled by data signals. Monochrome images are created by regulating the amount of transmitted light through the TFT array.

supply voltage ripple".) during luminance control. There is the possibility that the ripple

voltage produces acoustic noise and signal wave noise in audio circuit and so on. Put a

capacitor (5,000 to 6,000PF) between the power supply lines (VDDB and GNDB) to reduce the

noise, if the noise occurred in the circuit.

4.6 LUMINANCE CONTROL

4.6.1 Luminance control methods

Method Adjustment and luminance ratio PWSEL terminal BRTP terminal

x Adjustment

The variable resistor (R) for luminance control should be 10k: r5%, B curve, 1/10W. Minimum point of the resistance is the minimum luminance and maximum point of the resistance is the maximum luminance. The resistor (R) must be connected between BRTH-BRTI

Variable resistor control

terminals.

Note1: In case of the variable resistor control method and the voltage control method, noises may

appear on the display image depending on the input signals timing for LCD panel signal processing board.

Use PWM method, if interference noises appear on the display image!

Note2: The inverter will stop working, when BRTP signal is fixed to Low while BRTC signal is High

or Open. Then the backlight will not turn on anymore, even if BRTP signal is input again. This

is not out of order. Backlight inverter will start to work when power is supplied again. Note3: These data are the target values. Note4: See "4.6.2 Detail of PWM timing".

4.13 TEN-bit LOOK UP TABLE FOR GAMMA ADJUSTMENT

Adjustment of gamma characteristics for each 8-bit LCR data is possible by using built-in 10-bit LUT

(look up table) for Gamma characteristics.

The LUT is set with the serial data. The combination of the control command determines

Random/Sequential Address WRITE and Individual/Simultaneous LCR setting.

The serial data is composed as Table1.

Note1: Initial setting of the LUT is undefined data. The LUT should be enabled by setting of the GMA after

writing the LUT data in all the 256 addresses, in order to avoid undefined data display. Note2: Transfer the data every power-on, because the LUT data isn't stored in the LCD module. Note3: When writing and reading the LUT data, a noise may appear on the display image. In order to

prevent the noise appearing on the display, following measures should be performed.

(1)The LUT data should be rewritten during invalid period of pixel data (See "4.8 INPUT

SIGNAL TIMINGS".).

(2)The LUT data should be rewritten while the LUT data is invalid.

6.3.2 Environment

཰ Do not operate or store in high temperature, high humidity, dewdrop atmosphere or corrosive gases.

Keep the product in packing box and antistatic pouch in room temperature to avoid for dusts and sunlight, when customer stores the product.

ཱ In order to prevent dew condensation occurring by temperature difference, the product packing box

should be opened after being left under the environment of an unpacking room enough. Because a situation of dew condensation occurring is changed by the environmental temperature and humidity. Evaluate the leaving time sufficiently. (Recommendation leaving time: 6 hour or more with packing state)

ི Do not operate in high magnetic field. Circuit boards may be broken down by it. ཱི This product is not designed as radiation hardened.

6.3.3 Characteristics

The following items are neither defects nor failures.

཰ Response time, luminance and color may be changed by ambient temperature. ཱ The LCD may be seemed luminance non-uniformity, flicker, vertical seam 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.

ཱི Do not display the fixed pattern for a long time because it may cause image sticking. Use a screen

saver, if the fixed pattern is displayed on the screen.

ུ The display color may be changed by viewing angle because of the use of condenser sheet in the

backlight.

ཱུ Optical characteristics may be changed by input signal timings. ྲྀ The interference noise of input signal frequency for this product's signal processing board and

luminance control frequency of inverter may appear on a display. Set up luminance control frequency of inverter so that the interference noise does not appear.

www.panelook.com

NL256204AM15-01/01A

6.3.4 Other

཰ All VCC and GND terminals should be used without any non-connected lines. ཱ Do not disassemble a product or adjust variable resistors without permission of NEC. ི See "REPLACEMENT MANUAL FOR BACKLIGHT UNIT", if customer would like to replace

backlight lamps.

ཱི Pay attention not to insert waste materials inside of products, if customer uses screwnails. ུ Pack the product with original shipping package, in order to avoid any damages during transportation,

when customer returns it to NEC for repair and so on.

ཱུ The LCD module by itself or integrated into end product should be packed and transported with

display in the vertically position. Otherwise the display characteristics may be impaired.
