traffic control system, surgery/operation equipment monitor, disaster/crime prevention system,
etc.
The Specific: Applications as any failure, malfunction or error of the products might severe cause any
damage to death, human bodily injury or other property (Products Safety Issue) and the safety of the public
(Social Issues) and developed, designed and manufactured in accordance with the standards or quality
assurance program designated by the customer who requires extremely high level reliability and quality.
Examples: Aerospace system (except seat entertainment monitor), nuclear control system, life support
system, etc.
The quality grade of this product is the "Standard" unless otherwise specified in this document.

1. OUTLINE
1.1 STRUCTURE AND PRINCIPLE
Color LCD module NL204153AC21-17 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 data signals from a host system (e.g. 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.

Note2: The power supply lines (VDDB and GNDB) have large ripple voltage during luminance
control. See "4.3.4 Power supply voltage ripple ".
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.

*2: LVDS signals should be measured at the terminal of 100 : resistance.
Note1: If there is a voltage variation (voltage drop) at the rising edge of VDD below 10.8V, there is a
possibility that a product does not work due to a protection circuit.
Note2: LVDS signals must be set to Low or High-impedance, except the VALID period (See above
sequence diagram), in order to avoid the circuitry damage.
If some of signals are cut while this product is working, even if the signal input to it once
again, it might not work normally. If a customer stops the display and function signals,
VDD also must be shut down.
Note3: The backlight should be turned on within the turn-on period, in order to avoid unstable data
display.
Note4: After turning VDD on, terminal voltages on LVDS input terminals (*1) will rise. This is caused
by initial operation of the product.
