TFT COLOR LCD MODULE
NL10276BC26-01, 02
34 cm (13.3 TYPE), 1024 × 768 PIXELS, 262144 COLORS, INCORPORATED ONE LAMP/EDGE-LIGHT TYPE BACKLIGHT
DESCRIPTION
NL10276BC26-01, 02 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. The 34 cm diagonal display area contains 1024 × 768 pixels and can display 262144 colors simultaneously. By utilizing one lamp/edge-light type backlight, a very thin profile and low power consumption have been achieved.

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.
