1. OUTLINE
1.1 STRUCTURE AND PRINCIPLE
NL12876AC39-01 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 unit.
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.

0ms < t < 35ms
Note1: In terms of voltage variation (voltage drop) while VCC rising edge is below 4.8V, a
protection circuit may work, and then this product may not work.
Note2: Display signals (DA0+/-, DA1+/-, DA2+/-, DA3+/- and CK+/-) with 100Ω (Characteristic
impedance) must be Low or High-impedance, exclude the VALID period (See above
sequence diagram), in order to avoid that internal circuits is damaged.
If some of display 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 stop display signals,
they should be cut VCC.

Note1: These are the display signals for LCD panel signal processing board.
Note2: The backlight power voltage (VDDB) should be inputted within the valid period of display
signals, in order to avoid unstable data display.
Note3: The tr should be less than 800ms when BRTC terminal [Socket: CN202, Pin No.: 4] (See
"4.5.2 Backlight inverter".) is Open.
