1. OUTLINE

1.1 STRUCTURE AND PRINCIPLE

NL10276BC30-10 (S) module is 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 color-filter glass substrate.

Color (Red, Green, Blue) 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. Color images are created by regulating the amount of transmitted light through

the TFT array of red, green and blue dots.

1.2 APPLICATIONS

• Monitor for PC

1.3 FEATURES

• LVDS interface (8 bit)

• Selectable LVDS input map

• Wide color gamut

• High contrast

• Edge light type backlight (Inverter less)

• Replaceable lamp for backlight

Note1: This product consists of 2 backlight lamps, and these specification are for each lamp.

Note2: The lamp voltage cycle between lamps should be kept on a same phase. “VS” and “VBLH”

are the voltage value between low voltage side (Cold) and high voltage (Hot).

Note3: The asymmetric ratio of working waveform for lamps (Lamp voltage peak ratio, Lamp

current peak ratio and waveform space ratio) should be less than 5% (See the following figure). If the waveform is asymmetric, DC (Direct current) element apply into the lamp. In this case, a lamp lifetime may be shortened, because a distribution of a lamp enclosure substance inclines toward one side between low voltage terminal (Cold terminal) and high voltage terminal (Hot terminal).

When design the backlight inverter, evaluate asymmetric of lamp working waveform sufficiently.

|Sa - Sb| / Sb × 100  5%

Pa:

Supply voltage/current peak for positive, Pb: Supply voltage/current peak for negative

Sa: Waveform space for positive part, Sb: Waveform space for negative part

Note4: In case “FO” is not the recommended value, beat noise may display on the screen, because of

interference between “FO” and “1/th”. Recommended value of “FO” is as following.

FO = 1/4 x 1/th x (2n-1)

th: Horizontal signal period (See “4.9.2 Timing characteristics”.)

n: Natural number (1, 2, 3 ……)

Note5: Method of lamp cable installation may invite fluctuation of lamp current and voltage or

asymmetric of lamp working waveform. When design the backlight inverter, evaluate the fluctuation of lamp current and voltage or asymmetric of lamp working waveform sufficiently.

Note1: In terms of voltage variation (voltage drop) while VCC rising edge is below 3.0 V, a

protection circuit may work, and then this product may not work.

Note2: Display signals (D0+/-, D1+/-, D2+/-, D3+/- and CK+/-) and function signal (MSL) must

be “0” voltage, exclude the VALID period (See above sequence diagram). If these signals are higher than 0.3 V, the internal circuit is damaged.

If some of display and function signals of this product are cut while this product is

working, even if the signal input to it once again, it might not work normally. If customer

stops the display and function signals, they should be cut VCC. Note3: VCC should be 2.5 V or more while VCC ON period. Note4: The backlight power supply voltage should be inputed within the valid period of display

and function signals, in order to avoid unstable data display.
