Driving method of three-dimensional display device

A driving method of a three-dimensional display device including

• an image display portion capable of being oriented in a first mode to provide a portrait-type view and in a second mode to provide a landscape-type view and adapted to time-share an image to display a left eye image and a right eye image in a time-shared manner, and
• a parallax barrier having a first electrode set and a second electrode set arranged to extend along a first direction and further having a third electrode set and a fourth electrode set arranged to extend along a second direction perpendicular to the first direction,
• the parallax barrier adapted to receive the left eye image and the right eye image from the image display portion and to direct the left eye image and the right eye image toward a left eye and a right eye of a user, respectively,
• the driving method comprising:
• in the first mode, applying a first driving voltage to the first electrode set during a first period, the first driving voltage having a first level, and applying a second driving voltage to the second electrode set during a second period, the second driving voltage having a second level different from the first level;
• and
• in the second mode, applying a third driving voltage to the third electrode set during the first period, the third driving voltage having a third level, and applying a fourth driving voltage to the fourth electrode set during the second period, the fourth driving voltage having a fourth level different from the third level.

A driving method of a three-dimensional display device including

• an image display portion adapted to time-share an image to display a left eye image and a right eye image, and
• a parallax barrier for receiving the left eye image and the right eye image from the image display portion and for directing the left eye image and the right eye image towards a left eye and a right eye of a user, respectively, by operating a first electrode set of the parallax barrier and a second electrode set of the parallax barrier,
• the driving method comprising:
• applying a first driving voltage to the first electrode set during a first period, the first driving voltage having a first level;
• and
• applying a second driving voltage to the second electrode set during a second period, the second driving voltage having a second level,
• wherein the application of the first driving voltage produces a voltage drop over a terminal electrode of the first electrode set, and
• wherein the first level is set relative to the second level to compensate for the voltage drop over the terminal electrode of the first electrode set.
