Carry gear correspondence one suitable voltage magnitude of setting.
When actually implementing, it is preferred that when turntable driving a line, the electricity of the row pulse applied on any two row electrode
The absolute value of the difference of pressure amplitude value between 0 and minimum row pulse voltage amplitude/5, with the row pulse that prevents row electrode from applying
Voltage magnitude difference causes greatly very much display abnormal.
In the present invention, when minimum row pulse voltage amplitude refers to turntable driving this journey, it is applied to the row arteries and veins on all row
Minimum value among the voltage magnitude of punching.
In the present invention, the voltage magnitude of horizontal pulse refer to horizontal pulse itself maximum voltage value subtract minimum amount of voltage that after
Divided by the magnitude of voltage obtained by 2, similarly, the voltage magnitude of row pulse refers to that the row pulse maximum voltage value of itself subtracts minimum electricity
Divided by the magnitude of voltage obtained by 2 after pressure value.In the present invention, medium voltage Umid is directed to what is applied in a line of turntable driving
The maximum voltage value of horizontal pulse plus after minimum amount of voltage that divided by the magnitude of voltage obtained by 2, and the medium voltage Umid of row pulse
Medium voltage Umid with horizontal pulse is consistent.
For example, for maximum voltage value be 80V, minimum amount of voltage that for 0V horizontal pulse, its voltage magnitude be 40V, this hair
Bright middle signified medium voltage is 40V, so that row pulse can be the impulse wave that maximum voltage value is 70V, minimum amount of voltage that is 10V
Shape.Again for example, being 40V, the horizontal pulse that minimum amount of voltage that is -40V for maximum voltage value, its voltage magnitude is 40V, the present invention
Middle signified medium voltage is 0V, so that row pulse can be 30V, the impulse wave that minimum amount of voltage that is -30V for maximum voltage value
Shape.
Actually implement when, horizontal pulse can be high-frequency and high-voltage positive negative pulse stuffing, such as dutycycle be 50% high-frequency and high-voltage just
Negative pulse, it can also be the pulse of other forms certainly, and such as unidirectional pulse is unrestricted.
