DESCRIPTION
NL8060BC31-17 is a TFT (thin film transistor) active matrix color liquid crystal display (LCD) module comprising
amorphous silicon TFT attached to each signal electrode, a driving circuit, and a backlight.
NL8060BC31-17 has a built-in backlight. The backlight includes long-life-lamps and the lamps are replaceable
with a holder.
The 31 cm diagonal display area contains 800
600 pixels and can display 262144 color simultaneously.
NL8060BC31-17 is suitable for industrial application use, because the viewing angle is wide and the luminance
is high. Also, the viewing direction is selectable either upper or lower side by changing scan direction.
FEATURES

STRUCTURE AND FUNCTIONS
A color TFT (thin film transistor) LCD module is comprised of a TFT liquid crystal panel structure, LSIs for driving
the TFT array, and a backlight assembly. The TFT panel structure is created by sandwiching liquid crystal material
in the narrow gap between a TFT array glass substrate and a color filter glass substrate. After the driver LSIs are
connected to the panel, the backlight assembly is attached to the backside of the panel.
RGB (red, green, blue) data signals from a source system is modulated into a form suitable for active matrix
addressing by the onboard signal processor and sent to the driver LSIs which in turn addresses the individual TFT
cells.
Acting as an electro-optical switch, each TFT cell regulates light transmission from the backlight assembly when
activated by the data source. By regulating the amount of light passing through the array of red, green, and blue
dots, color images are created with clarity.

Notes1. The supply voltage for input signals
should be the same as V
CC
.
2. Turn on the backlight within the LCD
operation period. When the backlight
turns on before LCD operation or the
LCD operation turns off before the
backlight turns off, the display may
momentarily become white.
3. When the power is off, please keep
whole signals (Hsync, Vsync, CLK,
DE, R0-R5, G0-G5, B0-B5) low level
or high impedance.
4. Wrong power sequence may dam-
age to the module.
5. The signal should not be down dur-
ing operation. Even if signal could
recover, LCD module can not be
operated correctly, the display may
be un-uniformity. In case signal is
down, V
CC
should be turned off, and
then turn V
CC
and signal on as above
sequence.
