DATA SHEET
TFT COLOR LCD MODULE
NL6448AC30-12
24 cm (9.4 type), 640 × 480 pixels 4096 colors,
incorporated one lamp/edge-light type backlight (inverter-less)
DESCRIPTION
The NL6488AC30-12 is 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.
The 24 cm diagonal display area contains 640 × 480 pixels and can display 4096 colors simultaneously.
By utilizing one lamp / edge-light type backlight, a very thin profile design and low power consumption have
been achieved.
FEATURES

Description
4-bit digital signals for each of RGB primary colors
Horizontal synchronous signal
Vertical synchronous signal
Timing signal for display data. Module strobes the display data at the falling
edge of CLK.
The signal that defines the graphic data that is to be displayed on the screen.
When MODE = L, the function of this pin is ignored.
(Keep DE high or low)
When MODE = H, the period of DE = H is the display period of the module.
MODE = H : DE mode (data enable function is active)
MODE = L : fixed mode (data enable function is ignored)
VCCOFFO = H : Power on inside of the module
VCCOFFO = L : Power off inside of the module
Power supply for logic and LCD driving
Ground for VCC
