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

Storage on Gate structure. Note (4): Vcom must be adjusted to optimize display quality.
