NL10276AC28-01E
36 cm (14.1 type), 1024 ´ 788 pixels,
FULL-COLOR, MULTI-SCAN FUNCTION
INCORPORATED BACKLIGHT WITH INVERTER
DESCRIPTION
NL10276AC28-01E is a TFT (thin film transistor) active matrix color liquid crystal display (LCD) comprising amorphous
silicon TFT attached to each signal electrode, a driving circuit and a backlight. NL10276AC28-01E has a built-in
backlight with inverter.
The 36cm diagonal display area contains 1024 ´ 768 pixels and can display full-color (more than 16 million colors
simultaneously).
NL1276AC28-01E is a sucessor model of NL10276AC28-01.

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.
