Note (1): There is tolerance in optimum LCD driving voltage during production and it will be within
the specified range.
Note (2): VGH is TFT Gate operating voltage.
Note (3): VGL is TFT Gate operating voltage.
The low voltage level VGL signal must be fluctuates with same phase as Vcom in case of Cadd
(Storage on Gate) structure.
Note (4): Vcom must be adjusted to optimize display quality.
