AI Technical Summary
In the existing driving module, there is an overlapping period between the effective voltage duration period of the drive signals output by the odd-order and even-order driving circuits, which causes the data line to fail to obtain the normal data voltage during the overlapping period.
By controlling the control clock signal and output clock signal to the control circuit at all levels in the drive module, the effective voltage duration of the driving signal output of the N -level drive circuit output does not overlap each other.
The output of non -overlap dual pulse displacement is implemented to ensure that the data cable can obtain normal data voltage at all time periods.
