About the relation between data input and back light lighting, please base on the above-mentioned input sequence.
When backlight is switched on before panel operation or after a panel operation stop, it may not display normally.
But this phenomenon is not based on change of an incoming signal, and does not give damage to a liquid crystal
display.
