Document Type and Number:

WIPO Patent Application WO/2018/080279

Kind Code:

A1

Abstract:

The present invention provides a driving voltage control circuit comprising: a first voltage generator for outputting a first voltage; a second voltage generator for outputting a second voltage having an opposite polarity to the first voltage; a first switch for selectively transmitting one of the first voltage and a ground voltage; a second switch for selectively transmitting one of the second voltage and the ground voltage; and a third switch for selectively transmitting one of a voltage selected from the first switch and a voltage selected from the second switch, wherein a plurality of the third switches are provided, and the first switch is commonly connected to the plurality of third switches.
