SUPPLY VOLTAGE SEQUENCE
(1) Logic signals (synchronous signals and control signals) should be "0" voltage (V), when V
(2) LCD module will shut down the power supply of driving voltage to LCD panel internally, when one of CLK,
(3) The ON/OFF switching of backlight should operate while logic signals are supplied.
(4) Keep POWC signal "L" more than 200 ms after the power supply (V
(5) Analog RGB inputs are independent from this power supply sequence.
(6) It is better for the timing between logic signals and V
Wrong power sequence may damage the module.
CAUTION
higher than 0.3 V is input to signal lines, the internal circuit will be damaged.
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.
If the backlight power supply (V
