※ Data1: CLKIN±,RIN0±,RIN1±, RIN2±, RIN3±
※ Data2: SDA, SCL, LRI
※ About the relation between data input and back light lighting, we recommend the above-mentioned input
sequence.
If the back light is switched on before a panel operation begins or after a panel operation stops, the screen may
not be displayed properly. But this phenomenon is not caused by change of an incoming signal, and does not
give damage to a liquid crystal display.
