Abstract
A display apparatus including a display panel and a plurality of common voltage generators is provided. The display panel has a plurality of pixel regions. The plurality of common voltage generators are coupled to the plurality of pixel regions respectively and generate a plurality of common voltages, wherein each of the plurality of common voltage generators respectively maintains each of the plurality of common voltages at a first voltage, a second voltage, and a third voltage in a plurality of first timing periods in a first polarity period and respectively maintains each of the plurality of common voltages at a fifth voltage, a fourth voltage, and the third voltage in a plurality of second timing periods in a second polarity period in a narrow view mode, wherein the first voltage>the second voltage>the third voltage>the fourth voltage>the fifth voltage.
