Notes on Controller Transfer of Display Data

Since the LC75847T accepts the display data (D1 to D318) divided into three separate transfer operations when using

1/3 duty drive scheme and the data (D1 to D420) divided into four separate transfer operations when 1/4 duty drive, we

recommend that applications transfer all of the display data within a period of less than 30 ms to prevent observable

degradation of display quality.
