TFT COLOR LCD MODULE
NL10276AC24-02
31cm (12.1 type), 1024 × 768 pixels, Full color
Vertical screen expansion (Multi-scan), Incorporated backlight with inverter
DESCRIPTION
NL10276AC24-02 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. NL10276AC24-02 has
ma built-in backlight/inverter.
oThe 31cm diagonal display area contains 1024× 768 pixels and can display more than 16 million colors simul-
taneously because of analog interface.

Time
(1) Logic signals (synchronous signals and control signals) should be "0" voltage (V), when VCC is not input. If
higher than 0.3 V is input to signal lines, the internal circuit will be damaged.
(2) LCD module will shut down the power supply of driving voltage to LCD panel internally, when one of CLK,
Hsync, Vsync, DE (at DE mode) is not input more than 90 ms typically. During this period, the display data are
unstable. But the backlight works correctly even this period, and the backlight can be controlled by BRTC
signal.
(3) The ON/OFF switching of backlight should operate while logic signals are supplied.
If the backlight power supply (VDDB) is turned ON / OFF without logic signals, unstable data will be displayed.
(4) Keep POWC signal "L" more than 200 ms after the power supply (VCC) is input, if POWC signal is controlled.
(refer to PIN FUNCTION)
(5) Analog RGB inputs are independent from this power supply sequence.
(6) It is better for the timing between logic signals and VCC as follows.
