1. OUTLINE
1.1 STRUCTURE AND PRINCIPLE
Color LCD module NL6448BC20-21D 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. 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.

Note1: Please drive with constant current .
Note2: The Luminance uniformity may be changed depending on the current variation between 6 circuits.
It is recommended that the current value difference between each circuit is less than 5%.
Note3: See "4.2 ABSOLUTE MAXIMUM RATINGS Note4".
4.3.3 Power supply voltage ripple
This product works, even if the ripple voltage levels are beyond the permissible values as following
the table, but there might be noise on the display image.
