TFT COLOR LCD MODULE
NL128102AC23-02A
39 cm (15.4 inches), 1280 × 1024 pixels, Full-color, Multi-scan Function Incorporated backlight with inverter
DESCRIPTION
NL128102AC23-02A 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. NL128102AC23-02A has a built-in backlight with an inverter. The 39 cm (15.4 inches) diagonal display area contains 1280 × 1024 pixels and can display full-color (more than 16 million colors simultaneously). Also, it has multi-scan function. NL128102AC23-02A is a model which mounted the CRT interface board on NL128102AC23-02.

NL128102AC23-02A
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.
