Vcc-dip conditions
・
Hsync/Vsync need not be input so that this model may drive only by the ENAB signal.
・
The relation between the data input and the backlight lighting will recommend the above-mentioned input sequence.
When the backlight is turned on before the panel operates, there is a possibility of abnormally displaying.
The liquid crystal module is not damaged.
